Winter Weather, Ice Dams – And Mould In Your Home

Since mould occurs wherever there is moisture, you may be under the impression that the freezing cold temperatures of winter mean you can relax about at least one common household hazard.

Unfortunately, your optimism would be misplaced.

Freeze/Thaw/Freeze
This winter, Toronto and the GTA has seen its fair share of nasty weather, including mounds of snow, followed by days of freezing and liquid rain, followed be a re-freeze.

  • As the ice melts and rain falls, it can develop into streams running around – and sometimes very close – to your home.
  • Water may drain right into your basement.

Along with what’s occurring outdoors, your home creates its own environment.

  • Where there is heavy snowfall, followed by days of cold temperatures, the warmer air in your home may leak out through the attic.
  • This causes the snow and ice on your roof to melt.
  • The melted water will drain underneath the rest of the snow, along your roof, but is likely to re-freeze as it reaches the edge, forming icicles and ice dams.
  • Ice dams can actually damage the roof, causing water to leak into your attic.

Now that moisture is in your home, mould growth becomes a distinct possibility.

  • Where there is lingering moisture, mould can develop within 48 hours.
  • Mould can develop in the walls, floors, and ceilings, where you don’t see it.
  • Mould spores can also enter your HVAC system, spreading throughout your home.

Prevention
The general rule of thumb when it comes to mould prevention is this: maintenance.

  • Keep an eye on the area around your home, and remove whatever ice you can.
  • Make sure that any snow and ice formations flow away from your home – not towards it.
  • Make sure your attic is properly insulated to prevent heat leaks.
  • Make sure there are no other pathways for warm, moist air to leak to the attic through stairways, walls, or other areas.
  • Vent your dryer and stove to the outside of the building and not into the attic.

Asbestos Lessons To Be Learned From Social Housing Woes West of GTA

A social housing situation just west of the GTA puts the spotlight on maintenance when it comes to avoiding problems with asbestos and other potential hazards in your home.

The Situation
Residents of a public housing development in Hamilton have to relocate for periods of weeks to months as the building undergoes asbestos removal procedures. It will affect hundreds of people.

The building was constructed in the 1970s, when asbestos was commonly used in a variety of areas in residential and industrial construction.

  • Annual inspections found that leaky plumbing had caused the situation to occur on several floors of the building.
  • The asbestos became a problem when water damage issues caused ceilings to peel.
  • The building, like many of its era, featured popcorn – or textured – ceilings, where the texture was provided by none other than asbestos fibres.

The Work
Naturally, the project will be disruptive, but a city official quoted in a newspaper article said, “It’s a health and safety issue, not discretionary spending.” Air quality experts have gone through the building to determine asbestos levels for the safety of residents. Continuous monitoring will be crucial throughout the process.

  • It’s a 10-story apartment building, and the work will be done on one floor at a time.
  • Residents will be moved around to empty unit on other floors in the interim.
  • Vents and negative air pressure flows will be sealed off to prevent asbestos fibres from spreading as the work is ocmpleted.

What About Your Home?
There are a few key take-aways from this situation, whether you live in an apartment or condo, or own your own home.

  • Maintenance is key – asbestos and asbestos containing materials that are intact are not considered a risk.
  • The risk comes from dust or inhalable fibres, which can be caused by water damage, along with wear and tear over the years.
  • Great care must be taken in protecting you, your family, your neighbours, and even contractors working on your home from asbestos exposure.
  • Regular maintenance and inspection of your home’s major structures can find potential problems before they become a widespread and disruptive issue.

Old Home? – An Asbestos Horror Story

Just before the end of 2018, a homeowner in Winnipeg got a nasty surprise for the holidays – asbestos in the walls.

It was a water leak in an upstairs bathroom that led to a cascading series of woes. Unfortunately, the leak on a connector to the toilet tank began overnight, and by morning, had flooded the entire second story of the home, leaked into some of the first floor, and into the forced air vents of the HVAC system. A nightmare under any circumstances, to be sure.

The damage was so extensive, the family called in their insurance company, and the clean-up crew found something they weren’t expecting: asbestos. What they found specifically was asbestos within the drywall compound that had been in their walls.

Asbestos in Older Homes
The home was built in 1970, and was occupied by the same couple and their family since then. Like many people, they had a “if it’s not broke, don’t fix it” mentality, and so the home went with only a few necessary upgrades through the decades. It was a wake-up call the family won’t forget.

While the family may have been taken aback, the restoration crew was already on the alert.

  • Any homes built before 1990 have the potential for asbestos and asbestos containing materials (ACM) literally from floor to ceiling;
  • Asbestos or ACM may be found in floor and ceiling tiles, insulation, wall panels, even window caulking, textured paints, and carpet glue;
  • If the materials are intact and undisturbed, they are not considered a threat to health, but once major renovations or – as in this case – damage has occurred, it can cause the asbestos dust which can be inhaled.

That’s when the problem occurs.

Before You Renovate…
The lesson here is clear: if you own a older home, or if you are buying an older fixer upper, you need to find out what and where the asbestos may be located. Once you open walls and begin working – even if it’s something like a home theatre or alarm system installation – you are potentially creating inhalable asbestos dust.

  • If you are using contractors, you may be liable for their health and safety, including possible asbestos exposure;
  • If you are doing the work yourself, you are putting you, your family, and your neighbours at risk.

Asbestos: Can You Shrinkwrap Your Way To Safety?

The recent headline from upstate New York was nothing short of comical:

Ithaca woman wraps houses in plastic, fears asbestos from former library

The idea behind it, though, wasn’t a joke at all.

A Dangerous Demolition?
Scratch behind the surface of most headlines and you’ll find a more complicated version of the truth. Here’s the scoop: a woman in Ithaca, NY, did indeed seal up several properties she rents out with plastic because she was afraid of the risk of asbestos exposure and other harmful substances emanating from the demolition of an old library across the street.

The woman wrapped entrances and doors in thick plastic to protect the residents from friable asbestos dust and hazardous chemicals from the demolition project.

Is she right?

The project, involving the former Tompkins County Public Library, is a complicated one. The roof of the building is compromised, as verified by a structural engineer. Therefore, the city decided to do the asbestos remediation procedures and demolition at the same time – rather than removing the asbestos first.

  • Because of the simultaneous demolition/asbestos removal, all of the material from the demolition will be considered contaminated debris, and will be disposed of accordingly.
  • The demolition will be a controlled one. It means the building will go down one small area at a time to control debris, which should not disperse throughout the neighbourhood.
  • The area will be sprayed throughout the process to control dust.
  • Debris will be sprayed and covered nightly.
  • The water used for spraying will be filtered to prevent spreading asbestos and other substances.

In fact, the entire process resembles an asbestos removal procedure, with the added bonus of taking down the entire building as you do it. Controlling the dust and debris is the key component of safe asbestos removal and demolition work involving any hazardous substances. As long as those procedures are followed, we think the woman should feel secure that the risk of asbestos exposure has been minimized.

It’s an interesting look at a complicated case.

Marijuana, Mould & You

Mould – it’s not really what comes to mind first when you think about the legalization of marijuana. It was the top story throughout the country in fall 2018, and this in a year you wouldn’t describe as uneventful. But, the focus of attention has been on the buying and consuming end. The legislation, however, allows for Canadians to grow up to four marijuana plants themselves for personal use, and that’s where a little information on mould prevention comes in handy.

The Marijuana-Mould Connection
Marijuana can, in theory, be grown indoors or outdoors. The connection between marijuana cultivation and mould is all about humidity. Marijuana plants require high levels of humidity to thrive and grow.

  • Marijuana cultivation requires, at different stages of growth, humidity levels between 40 and 70 percent.
  • Humidity levels above 55 percent are associated with mould growth, particularly at 70 percent or above.

Here’s what you need to keep in mind.

  • First & foremost: if you can possibly grow it outside – including on a balcony – then that is the way to go, avoiding any increased risk of mould in your home. An online search will find you a reliable guide to its cultivation outdoors.

If you don’t have that option, then here is food for thought.

  • Marijuana grow-op operations have destroyed many homes. In a bid to prevent any of that due to legalization, Manitoba and Quebec have already banned any home growing operations.
  • In addition to high humidity levels, powerful grow lights may present a hazard.
  • Whether the humidity levels required for just four plants is enough to cause permanent damage may be arguable, depending on the size of the room, ventilation, and other factors.
  • If you do make the decision to go ahead, constant monitoring is essential.

The risk of mould is always present where there is increased humidity.

What About Insurance?

Most real estate and insurance experts advise against in-home marijuana cultivation because of the potential for mould and other damage. You may know there is a big difference between the four small plants in your back room and a huge commercial operation, but will future buyers of your home make that distinction – or will they pass you by just to be sure?

  • Most home insurance companies have already included a clause in their policies that specifically voids coverage on any property that is used for marijuana cultivation.
  • Companies may choose to make exceptions for the much smaller four-plant grows allowed under the new law, but that step has yet to be taken.

Insurance lawyer Jennifer Huneault (Hughes Amys LLP) was quoted in Gobalnews.ca on the subject.

“Insurance companies don’t tend to do home inspections before issuing policies, so that’s where we run into stigma,” she said. “Everyone has this idea of a grow-op, so it’ll be an uphill battle.”

House Fires And Asbestos – What To Do

House fires are devastating enough, what with the loss of property, and in some cases, irreplaceable items, not to say the overall trauma of the experience. But safety should always be a paramount consideration, and asbestos may pose a risk that you need to consider.

Asbestos in the home
Asbestos may be present in a home constructed before the mid-1980s. Absestos, and asbestos containing materials such as asbestos cement sheeting or asbestos vinyl tiles, may be found in a wide variety of places from floor to ceiling.

But asbestos is fire proof! you might be thinking, and you’d be right. That, and the fact it is virtually indestructible, is the main reason why it became known as a miracle material. However, the structures around it, and the materials it is mixed with, are not.

Putting Your Home Back Together
Potential asbestos exposure comes during the renovation process after a fire. Once the firefighters have gone, and told you it’s safe to return to your home, new dangers may emerge.

  • Any broken or damaged materials that cause dust, including exposed insulation, broken floor tiles, and even old appliance wiring in the walls, is a potential hazard that may contain asbestos dust.
  • It is tempting to think you can save money by sorting through everything, and doing the repairs, yourself, but you may be exposing yourself to asbestos dust.
  • Professionals use respirators equipped with high efficiency particulate air filters, and other specialized equipment to protect themselves.
  • A simple dust mask is not sufficient protection. Airborne asbestos fibres are extremely small, and will not be hindered by a dust mask.

Leave it to the professionals = that’s the best advice. A professional home inspector will be able to test for asbestos and any other hazardous materials.

Don’t Steal That Asbestos Removal Machine

A recent headline from the west coast couldn’t help but attract our attention: Richmond RCMP say stolen asbestos removal machine presents health risk.

Wait, what? Someone stole an asbestos removal machine, and we have to wonder why. A rogue asbestos removal outfit? Are things really that wild out west?

Whatever the motive, it was a dangerous move, both for the thieves, and anyone else who comes into contact with the equipment. If it isn’t being stored properly, it may pose a danger to anyone in the vicinity.

Asbestos Removal – It’s Complicated
The piece of equipment in question is called an OmniAire 2000, a device used to filter the air on demolition sites. Asbestos and other airborne contaminants are filtered out and away from workers. That means asbestos particles may be present in the machine itself.

We’re really hoping that the perpetrators of the theft aren’t intending on using the asbestos removal machine to do shoddy, unlicensed work. It’s a danger to anyone in the area because of one simple fact:

  • Asbestos dust is dangerous because it can be inhaled.

Because of that fact, asbestos removal procedures are complex and involve several steps. The type of job, based on the scope and extent of existing asbestos or asbestos containing materials, falls under a series of classifications numbered 1 through 3, with stipulations at every step of the way.

While the details may differ he basic steps in an asbestos removal operation remain the same,

  • Proper preparation of the area to be worked on;
  • Control of asbestos dust;
  • Use of specific equipment, including personal protective clothing;
  • Proper removal of waste and clean-up of the area once work is done.

Materials and equipment such as the air filtration machine are used to make sure the work can be completed while protecting workers as well as anyone living or working in the vicinity.

In other words, it’s a complicated job for experienced professionals. That’s where we come in.

Canada’s Asbestos Ban: Update

As our national asbestos ban in Canada takes its final shape, there are some details that have changed along the way. Recently, the federal government took the final steps to put the asbestos ban into place. Here’s a current update on the situation.

The Asbestos Ban
Canada was the biggest exporter of asbestos before the industry collapsed a few years ago, and our country has more than a century year old history or asbestos mining. There’s a lot left, too. There are more than 800 million tons of asbestos waste – containing up to 40 percent asbestos – in Quebec alone.

The new law will ban the importation, sale, and use of asbestos fibres, and the manufacture, import, sale, and use of any products containing processed asbestos fibres. But, that’s not the whole story.

• The government just awarded a $12 million contract to extract magnesium from the asbestos waste.
• Federal and Quebec regulations were, essentially, set by the asbestos industry itself, and currently allow exposure to workers at levels 10X higher than the US or in Europe.
• The federal government moved quickly to tighten the allowable asbestos exposure rates tenfold, to bring them in line with other Western nations. However, the Quebec provincial government has not done so, despite the endorsement of all 17 of the province’s directors of publish health, the Quebec Medical Association and other organizations.

In fact, the Quebec government’s directors of public health, and National Public Health Institute, called for including those millions of tons of asbestos waste in the new asbestos ban, but Environment Minister Catherine McKenna rejected their please.

“I am satisfied that these proposed regulations, along with existing provincial controls, will address the health risks associated with asbestos mining residues.”

A Double Standard
In essence, it creates a double standard, where those people who work on the existing asbestos waste will not receive the same protections under the law as anyone else. There are other exemptions under the law.

• Military and nuclear facilities will be allowed to continue to use asbestos until 2022.
• Chlor-alkali plants, which produce chlorine and sodium hydroxide for industrial purposes, are also exempt for a period of several years to come. It will be phased out by 2029.

Another exemption allows for use of asbestos containing materials where they “are required to protect the environment or human health where there is no technically or economically feasible alternative available.” In those cases, a one-year permit will be issued, with strict reporting requirements.

The law also says nothing about existing structures that contain asbestos.

Asbestos in the Storm

In late September, the Ottawa region suffered storm damage, including
a verified tornado. But, when old buildings are damaged, there is a
risk of asbestos exposure along with any other issues that arise.

Storm Damage
Many of the buildings in the Ottawa and Gatineau areas were
constructed prior to the 1980s, and that means they most likely
contain asbestos in one form or another. Subjected to the fierce winds
of the tornado, the building materials themselves were damaged.

“Part of the building’s roof was torn off, leaving a trail of dust
behind it,” said a spokes person for L’Office municipal d’habitation
de Gatineau (OMHG) in a radio interview, referring to one of the
buildings managed by OMHG, which is known to include asbestos.

Parts of the building were closed off to prevent the dust – and
asbestos fibres – from spreading. According to the report, the
organization will likely reconstruct the building rather that demolish
it.

The one saving grace? The rain likely meant that the dust didn’t
spread very far, even with the high winds.

What About Your Home?
If your home was built before the 1980s, it most likely contains
asbestos, and it may be found virtually anywhere from floor to
ceiling. When the material is intact, it is not considered a risk.

However, once the material has been damaged, it can release asbestos
dust. Once inhaled into the lungs, it never leaves, and can cause
serious health issues in the future, including lung cancers and deadly
mesothelioma.

There are many events which may damage asbestos and asbestos
containing materials and create friable – or inhalable – asbestos
dust. These include;

  • Renovations;
  • Fires, tornadoes and floods;
  • Installing home theatre or alarm systems that involve cutting into
    walls;
  • Replacing old piping or attic insulation;
  • And more.

If you plan on having any work done on your home, you need to know if
there is asbestos in the mix.

Asbestos in Roofing Materials

A recent remediation project at a daycare centre in Southwestern Ontario can serve as a reminder that asbestos really can appear virtually anywhere in a home from floor to ceiling – and even on top of that.

A Historical Problem
The daycare centre in Wingham, Ontario, has been housed in a building that has proved to be problematic over the years. Among other issues, it is believed that the roofing material – which was last replaced in 1976 – may contain asbestos. The county will pick up most of the costs of the roofing project.

The good news is that the authorities looking for a bid on the contract are already factoring in the possibility of asbestos removal into their call for tenders. As a home or property owner, if the building in question was constructed before the mid-1980s, there is a strong possibility it contains asbestos in one form or another. You need to take that into account whenever you are considering renovations or any installation that involved cutting into walls, ceilings, or floors.

When it comes to roofing tiles, asbestos is most often mixed with other materials. You may find asbestos or ACM (asbestos containing materials) in many areas of roofing.

  • Roofing Felt – a sheeting material made of thick compressed asbestos that can be used under shingles, or to build up a flat roof, often with asphalt
  • Roofing Shingles – often mixed with concrete in corrugated tiles, or with asphalt in flat tiles
  • Roofing tar – asbestos was often added to roofing tar mixtures to improve waterproofing and add a fire retardant
  • Sealants – no matter what type of tile or shingle was used, caulking and other roofing and window sealants may have also contained asbestos

The good news is that ACM used as roofing material is generally rated with a low friability rate, meaning that it is made to be durable and not deteriorate over time into inhalable dust. However, these materials were last used between the 1920s and the late 1970s, meaning they are already more than four decades old. The materials mixed with the asbestos may be deteriorating, leaving the asbestos itself to crumble.

What About Your Old House?
You love your old home, but there’s no denying that older buildings do require regular maintenance and, even though asbestos and ACM may have been installed decades ago, and have remained intact until now, the clock is ticking on all the materials and structures around the asbestos. How will you know exactly when it starts to crumble and create dust?

Don’t take the chance.
