5 Environmental Hazards from Building Renovations and Demolitions

With all the renovation shows on television these days and an endless stream of DIY guides online, it’s more tempting than ever to tackle home improvements yourself. Unfortunately, there are many things that are best left to the professionals when it comes to construction waste. Demolition services and environmental waste management are often seen as “nice-to-haves” from ambitious homeowners, but they are almost always a better option than tackling the problem on your own.


If you are renovating an old home, mould is almost guaranteed to present problems for you during removal. Spores from household mould can be extremely toxic and damaging to human health. Even with the proper equipment, many DIY-type will commit tragic errors in removal and disposal. Remediating mould is a professional skill that requires extensive training. If you have mould-ridden building materials, it’s a good idea to hire a trained and experienced specialist to tackle the job.


If you don’t know already, asbestos is one of the top concerns when renovating or demolishing an older home. Asbestos was extremely common as a fireproof insulator and building material that you will find in thousands of common products used in the past. Manufacturers would put it in all sort of different things – tiles, insulation, drywall, and many more. Before you start swinging your sledgehammer, you should strongly consider the services of an asbestos abatement specialist. They will quickly audit your home and let you know where any asbestos may be. Exposure to asbestos is a known cause of cancer, so it’s very important that you rely on professional help for removal and disposal.


Vermiculite is a common household building material used for decades before it fell out of favour in the 1990s. Vermiculite product manufacturers sourced most of the world’s vermiculite from a single mine, contaminated by high levels of asbestos. If you have vermiculite in your home, you should treat it just like any other asbestos materials. Leave it to the professionals, and let the experts worry about safe removal and environmentally-friendly disposal.

Dust and Airborne Particles

Any renovation or demolition project will feature a lot of airborne dust and particulate matter. While it’s tempting to tackle the problem yourself, you should rely on a professional team to minimize the cleanup required and reduce the risk of human health problems. Many people are extremely sensitive to dust and other allergens, and the professional services of a demolition expert will help you keep your family safe.

Glass, Nails, and Other Sharps

When you watch a renovation show on television, there is a lot going on behind the scenes that you don’t see. One of the most common hazards from demolition is sharp edges and protruding metal such as nails or bolts. It’s all too easy to cut yourself or injury your garbage collector with improper disposal of sharp materials. A professional-grade demolition company will safely and quickly remove any hazardous material, and you can rest assured that your construction waste won’t harm anyone.

The lowdown on mould spores

Black mold in the corner of room wall

With the wrath of weather we have seen in the Caribbean and Southern United States, now is a great time to talk about mould. Let’s take Hurricane Harvey for instance. We all saw the widespread flooding, the issues of low lying areas and of course the wind, but one thing that the news did not talk about is the widespread mould growth in the Houston area. As soon as flooding receded, the mould started to appear. It is well known in the remediation community that mould can grow within a single 24-hour period, but how is that even possible, and more importantly, what can you do to prevent it?

How mould works

You may be asking yourself who would mould be appearing a mere 24-hours after a flood, would it not take longer?! Well, the answer to that will take a little explaining. Let’s start with how mould works. Mold spores can be best described as an organism that is similar to pollen. They are very tiny and are in fact naked to the human eye, but they also are light as a feather and are able to float on air. Combine this with its ability to live a long time without a food source, and you can quickly see why mould is a bit of a problem. It also thrives outdoors, and while it cannot be active during winter, a spring thaw allows the mould spurs to be released from their dormant mode and mould will quickly become a threat once again. To survive, mould needs three things, oxygen, standing moisture and food. Their food source can be anything organic, but mould spores love cellulose which can be found in a number of textiles and carpets that are within the home. Mold is a serious concern, and you need to remember a few things about this dangerous spore and how to prevent it:

–    Repair any leaks in plumbing, roof, windows, or other sources of water as soon as possible to limit the possibility of mould growth

–    Mold will peak during the late summer and early fall due to the abundant wet vegetation that can be found throughout your area.

–    Use a dehumidifier to control excess moisture and high humidity when needed during the warmer months

–    Ensure that your home has adequate ventilation including an exhaust fan in your bathroom or any room with a shower.

–    Use a vacuum with a HEPA filter to help remove mould spores before they flare up

Why is it important

Mold is something to take care of immediately, and if left unattended will spread rapidly. Once a mould patch is large enough, it will produce more mould spores which will enter into your HVAC system and spread throughout the home, causing a true infestation. This is an issue as mould can cause a variety of issues that include:

–    A persistent cough or a dry throat

–    Irritation of the eyes

–    Stuffy nose

–    Respiratory issues

There is help on the horizon, and the first thing that you need to do is to call the team at Urban Environmental. We have been handling mould remediation services to the Greater Vancouver for years and will be able to get rid of your mould quickly and before it spreads to the rest of the house.


7 things to spot when looking for in a house that has a grow-op

Water leaks on the ceiling Causing damage, the ceiling tiles and cement.

Rental properties continue to be a popular method for a family to bring in a second income, and yet these properties are not without their risks. Damage to the property is possible as well as incidental costs that can add up are a regular occurrence. But, the worst possible scenario for a homeowner is dealing with a marijuana grow-op in the property. With this in mind, here are 7 things to look for in your property if you suspect a marijuana grow-op.

–    Ductwork

If you have never noticed ductwork before, now is the time to take a look up. Ductwork that is irregular and seemingly does not make sense in its current state could be a big hint that something is up with the property.

–    Circular holes in joists or ceiling

While looking up for the ductwork, make sure to check for patched circular holes. These holes will be where ductwork or ventilation would have been utilised for a grow-op on the property.

–    Changes to the exterior of the home

When taking your initial walk around the property, is there new siding, or new brickwork that has been completed without talking to you? Outside access is always necessary when growing plants inside, and the side of the house is normally the fastest way out for grow-ops.

–    Bald spots on the roof during winter

If you are lucky enough to live somewhere with an actual Winter, looking judgingly at your Vancouver, bald spots on the roof during the summer will be a huge red flag. Ventilation will either go through the roof or the side of the house, both of which will melt snow in a distinct pattern.

–    Modified wiring

Seasoned electricians will not make a mess of an electrical panel, and when hastily setting up a grow-op people do not care about the tidiness of their work. Look for bare wires, and a jerry-rigged electrical

–    Toxic Moulds in the basement or interior walls

Growing a plant indoors creates a humid environment, and with that comes mould. Look on the inside of windows, ventilation systems and of course the roof. Mould can be deadly and will be needed to be taken care of by professionals.

–    New plumbing in the basement

If you are the homeowner, you know your plumbing system, and if something seems off, it probably is. Make sure to look for water supply lines as well as drainage coming in and out of the room.

If you have spotted any of the above issues, especially toxic mould, you need to contact Urban Environmental immediately. We are the proven solution for those facing hazardous material removal issues in the Greater Vancouver area. If you have any questions about grow-ops or any other issues you may be facing contact us today.


Five of the best reasons to demolish a house

Demolishing a house can be a great thing when making room for a new home to go in its place. Whether it’s bigger, better or just plain new, it can be a great thing. With that in mind, here are the best reasons why demolishing your home to make room for a new one is a solid idea.

  1. Location:

    When someone owns a plot of  land on a lake, it is sometimes easier to remove a house and rebuild on the same spot. Whether it’s a bigger house that’s needed, or just the location that is perfect, by demolishing the house and building the perfect one in its place, demolition makes things much easier.

  1. Efficiency:

Using the land more efficiently is another reason to demolish a home as well. If the property lines change or the land erodes, it can open up or remove a lot of land, completely changing the layout of the system. By demolishing the home and rebuilding, it can use the land way more efficiently and improve the property value.

  1. The Perfect Home:

    Sometimes people have unrealistic expectations about their dream home. And sometimes instead of forcing a home to grow into the dream home, or letting the dream change, demolishing the original house to rebuild the dream home is easier than taking it one step at a time. By doing it all at one, and getting it right the first time it saves time, money and a whole lot of hassle.

  1. Safety.

Older homes have tons of little cracks and ticks that can leave a family in trouble. Sometimes, instead of waiting for that wall to fall, or the ceiling to come crashing in, it’s easier to plan it, demolish the home and take care of the family. When a home becomes unlivable and seems to be coming apart on its own accord, it just helps to do it before it can be done to you.

  1. Wildlife

    A very specific and dangerous reason to demolish a home can be because it is infested with wildlife. Whether it’s racoons, squirrels, or something like termites or ants, this can cause huge problems for a homeowner. Bugs like termites or ants can ruin a home, and are very difficult to get rid of, even with extermination. Once termites damage the structural integrity of the home, it is cheaper sometimes to break down the old home and build up a new one that will save time and money at the same time.

    There are many reasons to demolish a home and these are the top five. Saving the headache and the money, in the long run, gives great reason for the homeowners to demolish. By demolishing once, early, and making it count, they can maximise the value of the property while building their dream home or getting rid of the bugs. As extreme as it may seem, it follows the one and done mentality. By demolishing, the house, you something right the first time and it will pay off in the long run.

7 Way to Make Your Roof Last Longer

Man cleaning the rooftop from pine

Your roof is a principal component of your home, and if you live in a single family dwelling – it’s your roof alone. You’ve bought it,paid for it, and we imagine you’d like to get as many years out of it as possible. Needless to say, re roofing a home is an expensive venture. But when you get to that point, it’s not an optional one. You have to replace it!

As a premiere home restoration service provider here in Vancouver, those of us here at Urban Environmental have learned a thing or two (or two hundred) about what it takes to properly maintain a roof, so we’ll share some of that with you today.

All of this is particularly relevant given the fact that we live in the Lower Mainland of BC, which is a rain forest and gets a LOT of precipitation in the winter, not to mention the constant dampness that means your roof may still be wet long after the rain has stopped. There’s nothing you can do stop Mother Nature’s fondness for the wet stuff, so you’re only option is to be proactive in maintaining your roof

Here are seven tips and insights on how you can make your roof last for decades.

  1. General Inspections

If you want your roof to serve you for decades, you need to inspect your roof on a regular basis to see if there is no definitive structural damage occurring. Moreover, you need to do a thorough check-up before the onset of winter and after the wet season has passed. You will probably notice cracks and other points of breakage. Make sure you start your inspection at the ceiling. Keep an eye on rust when checking metallic materials on the roof. Ensure the flashing is in good condition. The general examination is important because it tells you if the roof needs repair.

If you notice something that looks damaged or not quite right in any way, now is definitely the time to move on it and prevent it from degenerating further.

  1.   Frequent Gutter Cleaning

Your gutters are hard working fellas, and if they don’t ever get a reprieve from all the debris and whatnot that accumulates there then you’re going to eventually have problems. Clean them – thoroughly and regularly.

It ‘s not a good idea attempting to clean from the top of the roof. What you need to do is to stand firmly on a ladder, making sure to avoid the top three rungs. You will need two buckets; one for the debris and another for the tools you will use. It is safe to use wire hooks when attaching the buckets to the ladder, and the best place to start cleaning is the downspout. A trowel is essential in removing large debris. For finer materials, a hose can be used to flush them. If you see the water not draining after cleaning, it may be a sign of the downspout clogging. Take the time to carefully remove the downspout and clear it before re-affixing it. Take the time to do it correctly – it’s well worth it in the long run

  1. Repair Broken Gutters

Yes, this is a more tedious task than cleaning, but if you do in fact have broken or damaged gutters you definitely want to be putting in the work now rather than later. If after you flush the gutters there is standing water remaining, it is a sign that the gutter needs repair. If the gutter doesn’t slope well, you should detach the hangers and fix the drain. Check if the hooks are missing and replace them. If the channel lengths are not tight, repair the seams. Apply some paint to cover any rusting so that the circuit may look desirable. There is usually a close connection between the gutters and the roof. If water is not flowing well, the water may overflow from the gutters, and later spread on the roofs.

Long story short, water and debris that linger in a gutter can (and likely will) become a threat to your roof’s structural integrity. Be proactive in repairing your gutters to

  1. Get Rid of Moss

Nip this problem in the bud. As soon as moss growth appears, get up there and remove it thoroughly. If you get after it right away it won’t take long or be a particularly laborious job. Moss affects asphalt and wood in particular. Moss starts growth as a thin layer between and on the shingles. With time, they lift the shingles and water can seep through, which can then lead to wood rotting. Don’t use a pressure washer – it can damage the shingles. Many home renovation and supply stores sell a moss remover product.

To prevent moss from returning, you can install copper or zinc coated metal sheets beneath the top ridge on either side of the roof.

  1. Trim Overhanging Branches

Overhanging tree branches aren’t harmless. Not only do they let wildlife access your house with greater ease, they can actually damage the roof themselves. While trimming tree branches, you need to take more care, especially while dealing with the large ones. The safest process is to cut the branches into small sections. It allows for easier removal without the risk of damaging the roof. Don’t hesitate to call in a tree trimming service if you think the job is going to be too much for you. Cut branches that tumble onto your roof can actually cause the damage you’re working to prevent.

  1. Remove Rust Spots on Flashing

Any iron or steel component that’s directly exposed on a roof top is going to rust. That’s just how it is. The rust will then stain – and degrade – your shingles or other roofing material. Keep the spots clean  by hosing them several times a year. Also considering using an additional sealant coating on the shingles that are in the path of the rusty water as it trickles away from the metal. Again it’s time consuming, but again it’s worth it.

  1. Replace Blistered Shingles

There are two primary reasons why shingles blister. The first is when moisture becomes trapped and then exterior temperatures vary. The other problem is when the roof is installed poorly and not properly ventilated. Blistering shingles are not a concern to many people if they still keep granules, but if allowed to continue unchecked they will eventually pop. When this occurs, it dislocates the granules. The shingles then become exposed to the UV rays, and the loss rate for the granules increases rapidly. Which eventually leads to – you guessed it – leaking. To prevent blistered shingles from progressing to this stage, replace them when you see the first signs of blistering. Replacing during the warmer months of spring or summer is highly advisable.

This is only an introduction. There’s much more you can do to maintain your roof long-term, so feel free to do some online research of your own. And of course, for any property restoration needs in Vancouver or the surrounding areas, you’re always in the best hands with Urban Environmental.


Homeowners Can – And Should – Be Proactive in Preventing Flooded Basements

mold and water damage from basement leak

It’s that time of year again in the Lower Mainland, and with this year’s recurring snowfalls that are often followed by rain when the temperatures sneaks back above zero (a very common trend in the Southwest corner of BC) there’s going to be more than a few flooded basements before spring arrives. We understand the concerns. We’re property restoration experts in Vancouver, but most of us are homeowners ourselves.

Naturally, homes in low-lying areas with subterranean basements are going to be most at risk, and we imagine the owners of those types of homes really don’t need to be appraised of this fact. There’s nothing we can do to convince Mother Nature to cease with blankets of snow followed by the deluges of rain, but smart homeowners will be proactive in taking steps to ensure their basement isn’t flooded. Or is flooded much less significantly than if they were to do nothing at all.

Let’s discuss these tips here.

The key word here in all of this, again, is proactive. You should be aiming to prevent or minimize flooding damage before it occurs. Let’s start with what you can do for the exterior of your home.

Exterior Considerations

  • Sealing cracks or openings in walls, floors, windows and foundations, and seal all window wells. If you don’t know how to effectively seal cracks and the right products to do so, learn it or hire a professional to do it for you (recommended of course)
  • Clearing eavestroughs and downspouts of leaves and other debris that prevent proper drainage. This one is doable for anyone, so get on it and complete the job thoroughly and regularly
  • Disconnecting your downspouts from the sewer system – this is also not particularly difficult or time consuming, and can be done right at the beginning of the season
  • Ensuring the grading around your home slopes away from the foundation wall to help drain water away from your home
  • Increasing the green space around your home with native plants and shrubs, and installing porous pavement to help absorb rainwater and melted snow
  • Repairing or replacing damaged weeping tile systems, which can magnify the volume of a flood in big way, particularly if the driveway lies flat or slopes down inwards
  • Ensuring drainage swales (shallow ditches) between properties are maintained and clear of obstructions

Now to the interior of your detached home

Interior Considerations

  • Ensuring plumbing and drainage systems are in good working condition. Keep in mind that homeowners are responsible for the plumbing, from the property line to the inside the home
  • Understanding how your plumbing and foundation drainage systems work, and how to maintain them. Every home is different and homes over time have been built with different building practices and building codes
  • Installing a backwater valve and a properly-sized sump pump and piping. If your home is in a high-risk area, having a sump pump on site and ready to go in event of an emergency is truly a very smart decision
  • Sealing cracks or openings in walls, floors, windows and foundations, and seal all window wells
  • Do not keep valuable possessions in subterranean areas of the home. A simple one, yes, but still worth mentioning.

Most homeowners in BC will have homeowner’s insurance. While it’s nice to know that you’re covered in the event of a flood, it’s still a particularly upsetting experience for most people. Being on top of everything you can do to prevent or minimize flooding is highly recommended, and particularly so these days with the trend towards more and more instances of flooding with our increasingly wild weather.

Here’s to your success with your preventative measures, and be sure to call us first for all your property restoration needs in Vancouver and surrounding areas.

Effectively Identifying and Remediating PCBs in Building Materials

UrbanEnvironmental.caAsbestos continues to be public-enemy #1 when it comes to building material contaminants that property owners want to quickly identify and be thoroughly rid of when it comes to their properties and the air quality within it. That’s perfectly natural given the health risks associated with breathing in asbestos fibres, but there’s another potentially airborne contaminant that was incorporated into building materials in far previous decades that needs some attention paid to it as well.

 PCBs, or Polychlorinated Biphenyls, were found in building materials used between roughly 1950 and 1979 in North America, both in Canada and the USA. As is the case with asbestos, one of the more common locations for them was in schools and other public-utility buildings and offices.

 Potential PCB Trouble Spots

 Here at Urban Environmental, we are equally experienced and adept with testing for and remediating PCBs in building materials. Let’s take a look at where they are most commonly found:

  •  Caulk put in place between 1950 and 1979 may contain as much as 40 percent PCBs and can emit PCBs into the surrounding air. PCBs from caulk may also contaminate adjacent materials such as masonry or wood.
  •  Fluorescent lighting fixtures that still contain their original PCB-containing light ballasts and have exceeded their designated lifespan have an increased chance of rupture and emitting PCB. Sudden rupture of PCB-containing light ballasts may result in exposure to the occupants and may also result in the addition of significant clean-up costs
  •  Some building materials – paint and masonry walls most notably – and indoor dust can absorb PCB emissions and then become potential secondary carry sources for PCBs. When the primary PCB-emitting sources are removed, the secondary sources often emit PCBs.

When it comes to removing contaminated caulk, it is preferable to use and electrical joint cutter with oscillating blade rather than any manual implement. A big reason for this is that the oscillating blade creates a low volume of dust and there is typically a low risk of damage to joint faces when the work is conducted by a skilled and experienced tradesperson.

A rotary cutting tool can be used too, and some remediation technicians will use dry ice blasting, which is also very effective but expensive and comes with complex requirements for protective measures.

 Like any remediation process when contaminants that pose health risks may be present, it must be undertaken by industry professionals. Property owners can be proactive in identify the possibility of it though, and in particular by identify products by their manufacture date or classification.  With fluorescent lighting, look for the following indicators:

  •  A black, tar-like substance inside the small capacitor within the FLB or in the potting material. If an FLB fails or over heats, the capacitor may break open resulting in release of its oils and potting materials
  •  A yellow, oily liquid or in the tar-like potting material that leaks from the FLB

 The capacitor does not always leak when the FLB fails, and a leaking capacitor does always cause FLB failure. A leaking or rupturing FLB may increase PCB levels in the air, therefore, measures should be taken to limit or avoid personal exposure. 

 Airborne contamination stemming from degrading paint and masonry walls is measured by a Toxic Organic Compounds in Ambient Air test, with one of 2 tests determined by a high or low air volume. This approach is usually paired with wipe sampling testing from the suspected source material(s), and between them we are extremely reliable at identifying and then removing all PCBs via the offending building materials.

 Urban Environmental is Greater Vancouver’s premiere home and commercial property remediation service provider, and we’re proud of our nearing 2 decades of meeting and exceeding customer expectations and maintaining an ‘A’ rating with the Better Business Bureau. If you have any reason to suspect airborne contaminants in your home or business property, please call or email us without delay.


Tips and Tricks to Prevent Mold in your home

Mold, it is one of the biggest issues that many homes face on the West Coast, and yet you can avoid this expensive and dangerous issue. We here at Urban Environmental have brought together some of the top tips on how to avoid getting mold, and how to deal with water within the home.

  • Remove those items that may cause mold

This seems simple, but yet many who have mold tend to forget to remove problem items from their home. Take a look in your basement, and make sure to limit the amount of stored materials within it. If you have badly damaged items or ones that reek of must, throw them out. Avoid storing firewood within the home; try the side of the house, or a simple shed to place it in. If you have carpet that is damp, remove it and that goes for bathrooms and basements especially. Finally, do not store things in cardboard boxes on your basement floors; it just simply avoids future issues that may arise.

  • Maintain a dry and clean home

This is a very simple point. If you have a clean and dry surface that gets wet, make sure to take care of it. Whether you need to add drip pans for air conditioners, refrigerators and dehumidifier, or make sure to take care of the walls around your shower or toilet.  Keep your home dry and clean and you will enjoy a mold free house.

  • Limit indoor moisture sources

Moisture loves to get inside the home, and you need to work hard to keep it out of the home. Try to avoid airing your laundry indoors, and make sure to remove dryer lint after each use. Watch for signs of mold on plants, and make sure to take out garbage regularly. Some simple changes and you will enjoy a mold free home for the future.

  • Prevent water from entering the home

Make sure to install downspout extensions throughout the home to take rainwater and melted snow away from your foundation. Ensure that your eaves troughs and roof gutters are connected, and do not leak. A clean gutter that takes water away can make a world of difference for your home, and ensures your home is mold free.

However, if water does come into your home, you will need to take some very important steps in a short amount of time.

  • Disconnect the power

On top of this, you will also need to unplug and remove your portable electronics, and clear the area of furniture and movable items.

  • Remove the water

There are a number of ways to do this, but the most popular are: manual work with towels, buckets and mops, or with machines, whether it be a shop vac or a sump pump.

  • Start to dry the affected area

Fans and dehumidifiers are going to be your best friend in this step, and you will need to work hard to ensure the entire area is truly dry.

  • Disinfect the area

This includes walls, baseboards, floors and every other surface that might have microbes on it. Make sure to work hard and use an industrial or tough disinfectant to ensure it works.

  • Prevent Mold Growth

Follow the aforementioned steps above to ensure you do not have a future mold problem!

If you do happen to have a mold problem, and you need it taken care by professionals, call the team at Urban Environmental for their amazing mold removing service. We have been dealing with mold for years, and know how to best remove and destroy the mold for good.  Call us today, and enjoy a mold free environment for your home or office.

Common Asbestos Myths

UE-AsbestosMyths-bThese days, almost all of us are aware of the dangers asbestos can pose, we realize the importance of having a specialist deal with any job which may involve disturbing or removing asbestos. However, the general public’s awareness has not always been as good, which has led to some peculiar myths about asbestos. Here are some of the most common:

1) New build properties are free from asbestos.

Don’t assume that because your house or office is a new build that you’re not at risk. A 2014 HSE survey showed that only 15% of people knew that asbestos was still used in buildings up until the year 2000.

2) You can remove asbestos from your system if you act quickly.

 An HSE survey showed that 14% of people believe that if they had a drink, after exposure to asbestos dust, they weren’t at risk from asbestosis. Another 27% thought they’d be okay if they opened a window in a room with asbestos dust. This is not true. Anyone handling asbestos must follow strict guidelines to protect themselves, which involves protective clothing, face masks and specialist sealants.

3) Mesothelioma is contagious.

You can’t catch mesothelioma from an afflicted person. However, it is possible to contract it if you share a home with someone who works around asbestos, who unintentionally brings home items which are contaminated with asbestos fibres.

4) If you find asbestos in your home, you must remove it immediately.

As long the material containing asbestos is not damaged, there is no immediate risk to your health. In fact, panicking and ripping it out can cause more harm than good. It is strongly advised to hire a licensed asbestos contractor, who can provide further advice.

5) Wearing a mask means you won’t breathe in any asbestos fibres.

Asbestos contractors wear specialist face masks with filtration, designed specifically to protect them from breathing in the fibres which cause mesothelioma. Simple masks from the DIY shop cannot provide adequate protection.

6) How to really protect yourself from breathing Asbestos:

Asbestos fibers can enter the body through the air we breathe, which is why it’s important to have respiratory protection in case of asbestos exposure. A respirator is a device designed to provide clean oxygen to the people who are wearing or surrounding the device. Here are three examples of respiratory devices used to protect against the dangers of asbestos exposure.

– Air Purifying Respirators

Air purifying respirators clean the air by passing it through a filter before it reaches you. They generally come in the form of a mask that the wearer puts over their face. These respirators either have a mechanical filter for fumes, a chemical filter for vapours, or a combination of both. In order to be effective against asbestos, air purifying respirators must have a minimum efficiency level of 99.97% as certified by the National Institute for Occupational Safety and Health (NIOSH).

– Supplied Air Respirator

These respirators provide clean air to the wearer through a mask that is connected by a hose to an external air source. A supplied air respirator is more secure than an air purifying respirator and thus is worn in more severe cases of asbestos exposure. All supplied air respirators must meet relevant health and safety standards if they are to be used.

– Self-Contained Breathing Apparatus

These respiratory devices involve a portable oxygen supply that is placed on the wearer’s back. Oxygen is supplied directly to the wearer via a portable tank. While this respiratory device is the most effective against airborne toxicity, it is also more cumbersome and therefore not always suitable for asbestos abatement procedures.

When asbestos is disturbed, particles are released into the air that can affect anyone who breathes them. While respiratory devices may provide temporary relief, the only permanent solution to asbestos exposure is to have it professionally removed. For more information about our professional asbestos abatement procedure and/or to have your property inspected for asbestos, contact Urban Environmental today at Certified Asbestos Removal and Restoration.

On average, about 200 people per week are currently falling victim to asbestos related diseases. Thankfully, as awareness about the danger of asbestos grows, and knowledge of risk reduction increases, the number of fatalities should fall.

Urban Environmental has fully trained and experienced staff to help you deal with asbestos in your British Columbia office or home, leaving you to enjoy your environment with the peace of mind you deserve.

Asbestosis and Other Remaining Major Asbestos Diseases


This is a continuation article on on asbestos-related disease listing, detailing some of the most debilitating and deathly asbestos-caused diseases.

Many thousands of scientific & medical publications have chronicled the understanding of the plethora of hazards of asbestos to human and other air-breathing, and even aquatic life.  The development of today’s level of  understanding began during the industrial revolution -most notably from the textile factories and mineral mines of Great Britain, Canada and the United States

This body of knowledge is frequently referred to in mountains of asbestos related litigation that has been taken to the courts since.   Related medical publications have been used for determining if an asbestos using company acted within the bounds of negligent behavior.

The following list of diseases regarding asbestos fibers as it pertains to humans:

Asbestosis was given that name as it is the most common asbestos-caused chronic lung disease.   Generally Asbestosis implies scarring of the lung tissue; which results from prolonged exposure to asbestos. It’s other longer definition is “diffuse interstitial pulmonary fibrosis’.   The lungs are directly affected and the disease typically manifests after 15+ or more years from initial and prolonged exposure to airborn fibers.

Asbestos-related fibrosis is “progressive” because it continues to progress in the lung tissue; even if no further asbestos is inhaled.  Scar tissue hardens the lungs, limiting elasticity.

The sharp jagged fibers scars the lung tissue and causes the alveolar walls to thicken, which reduces lung capacity and leads to the patient experiencing shortness of breath (dyspnea).

Breathing even becomes painful as the condition progresses. Scarring also impairs the lungs’ ability to supply oxygen to the blood stream; therefore patients often need oxygen tanks and pain medication to control symptoms.

There is no cure for asbestosis and its progression can’t be halted, but most symptoms are minimized with medication and oxygen supplementation. Sufferers have an increased risk for cancerous malignancies and for heart failure.

Asbestos-related lung cancer

Asbestosis often leads to lung cancer; which identical to lung cancer from smoking. Exposure to asbestos is associated with all major histological types of lung carcinoma:   small-cell carcinoma, adenocarcinoma, squamous cell carcinona, and large-cell carcinoma.

The time period between exposure and development of lung cancer is typically 20 to 30 years. Estimations average between 3%-8% of all lung cancers are related to asbestos. The risk of developing lung cancer depends on the amount, duration, and frequency of asbestos exposure (cumulative exposure).  Smoking is a contributing factor towards lung cancer; smokers who have been exposed to asbestos are at far greater risk of lung cancer.  Smoking and asbestos exposure have a multiplicative/synergistic effect on the risk of lung cancer.

Symptoms of lung cancer include chronic cough, chest pain, breathlessness, haemoptysis, (coughing up blood), vocal hoarseness and wheezing, weight loss and fatigue. Treatment involves surgical removal of the cancer, chemotherapy, radiotherapy, or a combination of procedures. Prognosis is generally poor unless the cancer is detected in its early stages. Out of all patients diagnosed with lung cancer, only 15% survive for five years after diagnosis.

Thanks to informational commercials and infrequent news reports, most people have become aware that asbestos exposure causes mesothelioma and lung cancer. However it is less generally known that asbestos also causes/promotes cancer of the voice box (larynx) and female ovaries.

Also asbestos actually causes more benign conditions than cancerous ones. Familiarity with these other asbestos-related diseases helps those previously exposed know what symptoms to watch out for as signs of a developing condition.

Noncancerous asbestos conditions range from mild & nonthreatening to severe & life-threatening. Modern treatments and medications have improved quality of life for people coping with these conditions.
Some of the asbestos diseases listed below are life-threatening. However, an early diagnosis can make all the difference in terms of survival.

Laryngeal Cancer

Laryngeal cancer is rare and most often caused by smoking in combination with alcohol consumption. Yet a 2006 report sponsored by the National Institutes of Health proved that asbestos exposure causes cancer of the larynx, known as the voice box. In 2012 the IRAC confirmed the connection in a scientific review of all evidence to date.

Researchers suspect that inhaled asbestos fibers lodge in the voice box on the way to the lungs. Treatment varies by cancer stage and involves surgery, chemotherapy and radiation therapy. The prognosis for small tumors that haven’t spread to lymph nodes is good with cure rates between 75 and 95 percent. If caught early enough, radiation therapy may offer a cure and preserve the patient’s voice.

Ovarian Cancer

Though it only represents 3 percent of female cancer diagnoses, ovarian cancer causes more deaths than any other female reproductive cancer. In 2012, a IARC study confirmed that asbestos exposure causes ovarian cancer. Many cases were documented in women whose father or husband worked with asbestos.

Though the exact mechanism for how asbestos fibers reach the ovaries is under debate, researchers theorize the fibers are transported by the lymphatic system. Some cases were associated with talcum hygiene products that were contaminated with asbestos.

Ovarian cancer is treated with surgery, chemotherapy, radiation therapy, hormone therapy and targeted therapy. The overall survival rate for all types and stages of ovarian cancer is 45 percent. A fortunate 15 percent of cases are diagnosed in stage I and have a 90 percent survival rate.

Benign Pleural Diseases

While conditions like asbestosis and lung cancer affect lung tissue, other conditions affect the lining of the lungs known as the pleura. Mesothelioma is the only cancerous disease that affects the pleura, yet asbestos can cause several benign conditions to develop in the lung lining.

The pleura contains two layers: An inner layer that lines the lungs, and an outer layer that lines the ribs. The presence of asbestos fibers can cause these layers to inflame and rub against each other, a condition called pleuritis. Medication is effective at controlling pain.

As scar tissue accumulates on the lining of the lungs, collagen deposits called pleural plaques can develop. Plaques most often form on the outer layer of the pleura that lines the rib cage. Between 5 and 15 percent of plaques become calcified and harden as a result. They rarely cause symptoms, but some plaques may cause pain and could require medication.

Inflammation caused by asbestos can weaken blood vessels, causing them to leak fluid. This fluid builds up within the pleural layers, called pleural effusion, and can interfere with breathing and cause pain if left untreated. A procedure called talc pleurodesis can permanently prevent fluid buildup.

Pleural effusions often precede extensive scarring and thickening of the pleura, known as diffuse pleural thickening. As the pleura becomes rigid and thick with scar tissue and lung function is compromised, pain may develop. Medications for pain, bronchial dilation and steroids offer relief from symptoms.

If you have a history of asbestos exposure and develop any abdominal, pelvic or pulmonary pain or dysfunction, visit a primary care doctor or specialist immediately. Prognosis is improved and treatment is more effective for all asbestos-related conditions when diagnosed early.

Non-malignant asbestos-related pleural diseases

Benign asbestos-relatedpleural abnormalities encompass four types of pleural changes:

·    Pleural plaques
·    Diffuse pleural thickening
·    Benign asbestos pleural effusions
·    Rounded atelectasis (folded lung)

The pleura appears to be more sensitive than the lung parenchyma to the effects of asbestos fibres. Thus asbestos-related pleural diseases can result from much lower doses than the fibrotic changes in the lung.
Pleural plaques

Pleural plaques are the most common manifestation of asbestos exposure, affecting up to 58% of asbestos-exposed workers. The prevalence among the general population exposed environmentally ranges from 0.53 to 8%. Pleural plaques are discrete circumscribed areas of hyaline fibrosis (patches of thickening) of the parietal pleura and rarely the visceral pleura; which develop 20 to 40 years after first exposure. Over time, usually more than 30 years, they often become partly calcified. They consist of mature collagen fibers arranged in an open basket-weave pattern and are covered by flattened or cuboidal mesothelial  cells.They have a white or pale yellow shaggy appearance and are typically distributed on the posterolateral chest wall, diaphram, and mediastinal pleura. The number and size varies. Pleural plaques are typically asymptomatic, however, there is still some controversy on this topic.

An association between pleural plaques and chest pain has been reported.  Similarly, an association between pleural plaques and a restrictive impairment with diminished diffusing capacity on pulmonary function testing has been observed.  This has not been a consistent finding and it has been postulated that this might be related to undetected early fibrosis.  The pathogenesis of pleural plaques remains uncertain. The most likely explanation is that asbestos fibres reach the parietal pleura by passage through lymphatic channels where they excite an inflammatory reaction. The chest X-ray is the usual tool for diagnosing pleural plaques but chest CT scans are more sensitive and specific in this regard. Pleural plaques are evidence of past asbestos exposure and indicate an increased risk for the future development of other asbestos-related diseases. Pleural plaques in themselves are not pre-malignant. Individuals with pleural plaques are usually not compensated in most compensation systems.

Benign asbestos pleural effusion

Benign asbestos pleural effusion is an exudative pleural effusion (a buildup of fluid between the two pleural layers) following asbestos exposure. It is relatively uncommon and the earliest manifestation of disease following asbestos exposure, usually occurring within 10 years from exposure. Effusions may be asymptomatic but rarely, they can cause pain, fever, and breathlessness.  Effusions usually last for 3–4 months and then resolve completely. They can also progress to diffuse pleural thickening. Diagnosis relies on a compatible history of asbestos exposure and exclusion of other probable causes.

Clubbed Fingers

About half of all people with severe asbestosis develop a condition known as clubbed fingers. The tips of fingers become misshapen, swollen and may take on a box-like appearance. The condition appears to be caused by the biological effects of asbestosis rather than directly by asbestos fibers.

Clubbed fingers tend to develop early and don’t go away once developed. It is a sign of more severe asbestosis and is associated with higher mortality and likelihood of disease progression.

Rounded atelectasis

Rounded atelectasis (also known as Blesovskys or folded lung syndrome) develops from infolding of thickened visceral pleura with collapse of the intervening lung parenchyma.  It presents radiographically as a mass and may be mistaken for a tumour. On a CT scan of the chest it appears as a rounded mass like opacity in the peripheral lung adjacent to thickened pleura and with curvilinear opacities which are the bronchi and vessels (comet tail).

Rounded atelectasis is the least common asbestos-related benign pleural disease. Exposure to asbestos is the most likely cause today but it can occur following other medical conditions. It is a chronic condition and usually asymptomatic.

In Summary:

Asbestos is perpetually and persistently dangerous.  It should have never been used in building material for homes and offices.
