The toxic threat of “Chinese drywall” to homes in Canada

While the risk of asbestos in home construction has been long recognized and action taken to stop it, a less well-known recent threat is the use of an extremely toxic drywall that was imported from China during the U.S. housing boom of 2004-2007 to satisfy the drywall shortage, and in response to natural disasters such as Hurricane Katrina. Many thousands of homes in the U.S. have been irreparably damaged by this substance, and the homeowners sickened, leading to extensive lawsuits.

Although there was no similar shortage in Canada, the defective drywall found its way into the country through Vancouver and has reportedly spread to the Prairies and eastward to Toronto. By 2009, many homeowners in British Columbia had reported illnesses linked to its use. The full extent of the toxic drywall crisis in Canada has yet to be revealed.

The effects of “Chinese drywall” are devastating

The devastating effects of this drywall are caused by the toxic sulphide gas it emits. When the gas comes into contact with household humidity, it gives off a noxious odour as it erodes any exposed copper or lead in the home, with the following effects:

scorched and blackened wiring behind wall plugs and switchplates
corroded coils on air conditioning units
malfunctioning of light fixtures and other electrical equipment
blackened wiring in cable televisions and converters
ruining of personal property such as jewelry and silverware
As well, affected homeowners may develop respiratory problems, eye irritation, headaches, fatigue, dizziness, sore throat, and nosebleeds. Pets have died from exposure.

No repair is possible

Only a few sheets of the drywall can render homes unsafe and uninhabitable. The contaminated home cannot be repaired. The only possible recourse is to move out, gut the house, and rebuild the interior.

The drywall can be identified by the manufacturing label of KNAUF PLASTERBOARD TIANJIN (KPT). If it is discovered in your home, then promptly seek legal advice to ensure that your right to future financial compensation for your potential losses is protected.

Understanding Black Mold and Condensation Issues in Houses

As the summer heat sets in, many homeowners find themselves dealing with a hidden adversary: black mold. While it’s often associated with damp, dark conditions, black mold can thrive in warm, humid environments, making summer a prime season for its growth. Let’s explore how condensation contributes to this issue and what you can do to prevent mold problems in your home. The Science of Condensation Condensation occurs when warm, humid air comes into contact with cooler surfaces, causing moisture to form. This is particularly common in the summer when the outside temperature is high, but the inside of your house may be cooler due to air conditioning. Common areas where condensation accumulates include: Windows : The temperature difference between the outside air and the glass can lead to moisture forming on the surface. Walls and Ceilings : Poorly insulated walls may cool down significantly, allowing condensation to form on them. Bathrooms and Kitchens : Areas that generate steam from s...

How Fire and Smoke Affect Air Quality: Understanding the Impact

Fires, whether wildfires, controlled burns, or residential incidents, have a profound impact on air quality. The smoke produced by these fires contains a complex mixture of gases and fine particles that pose significant health risks. Understanding how fire and smoke affect air quality is crucial for both public health and environmental management. This blog post delves into the components of smoke, the effects on air quality, and the measures one can take to mitigate these impacts. Components of Smoke and Their Impact on Air Quality Smoke is composed of a variety of pollutants, each with specific properties and effects: Particulate Matter (PM) : Fine Particles (PM2.5) : These particles are smaller than 2.5 micrometers in diameter and can penetrate deep into the lungs and even enter the bloodstream. PM2.5 is particularly harmful as it can cause respiratory and cardiovascular issues. Coarse Particles (PM10) : Larger particles that can still cause respiratory problems but are genera...

When should I call a Mold Removal Specialist?

Housecleaning can be fun if you’re just dealing with dust and grime. With household cleaners, towels, a broom, a mop, and a vacuum cleaner, you might have a clean house by the end of the day and feel amazing. Housecleaning with mold, however, is an entirely different story. No amount of mopping or vacuuming will help you get rid of mold. If the mold growth covers an area of more than 10 square feet (the size of a bath towel), you should consider calling a mold specialist. Cleaning large areas of mold can can be tricky. Mold spores are airborne and very hard to keep contained. For cleaning small amounts (10 square feet or under), we recommend using a specifically mold or mildew cleaning product. There are several different brands that will work fine at your local Home Depot or Lowe's. BUT WHY SHOULD I CALL MOLD REMEDIATION SPECIALISTS Mold removal professional are trained and equipped to deal with all sorts and sizes of mold growth in the most systematic manner possi...
