Why Asbestos Still Matters in Older Calgary Homes
We don’t usually think about hidden dangers in the walls or ceilings of our homes. However, if you live in an older home in Calgary, there’s a good chance asbestos might still be present. We’ve seen it more often than you’d expect. During renovations or repairs, what looks like a harmless ceiling panel or old duct wrap could actually be contaminated with asbestos. That is to say, the danger is usually invisible.
Asbestos was once common in building materials across Canada. Consequently, many homes built before the late 1980s still contain asbestos in materials like insulation, ceiling tiles, flooring, and drywall compound. We know homeowners want to be safe. At the same time, most people aren’t sure what to look for, or when to take action.
Common Places Where Asbestos Might Be Hiding
We’ve inspected hundreds of Calgary properties, and certain materials come up repeatedly. Firstly, popcorn ceilings are a big one. They often contain asbestos, especially if installed before 1990. On the other hand, even newer ceilings aren’t always safe if old materials were reused during repairs.
Secondly, vinyl floor tiles can be a hidden source. The backing and adhesive of 9×9 or 12×12 tiles may contain asbestos. This becomes a concern during floor removal or sanding. In addition, we often find asbestos in attic insulation, especially vermiculite. This material looks like small, pebbly granules and was commonly used for decades. If disturbed, it can release asbestos fibers into the air.
Lastly, drywall compound and joint tape from older renovations can be a problem. While the drywall itself may be safe, the mud and tape used to finish it often contained asbestos. That is why renovation projects involving demolition or sanding walls should always begin with asbestos testing.
Warning Signs That Asbestos May Be Present
There is no obvious visual cue for asbestos, which makes it especially tricky. That said, we can spot risk factors based on the age of the home and condition of the materials. For instance, if you notice discolored insulation in your attic or ceiling texture starting to flake, those are signs to proceed cautiously.
Above all, if your home was built before 1990 and you plan to do any renovations, we strongly suggest a proper inspection. Even untouched asbestos is dangerous once it gets disturbed. For instance, drilling into a ceiling tile or cutting into a wall during a remodel can release microscopic fibers into the air. These fibers are not only harmful but very difficult to remove once airborne.
We’ve also come across many homes where past renovations left behind layers of both safe and hazardous materials. In other words, just because a wall looks new doesn’t mean it’s free of asbestos underneath.
Why Testing Is the Only Reliable Way to Know
Unfortunately, you can’t rely on guessing or visual inspection alone. Therefore, the only reliable way to determine whether a material contains asbestos is professional testing. We collect samples using proper containment methods and submit them to certified labs for analysis. As a result, you get clarity without unnecessary risk.
Testing is especially important before starting demolition, sanding, or cutting into any material that might contain asbestos. Many homeowners are surprised to learn that even a simple flooring replacement can trigger exposure. Similarly, plumbing or electrical work in older homes often cuts through drywall or ceilings that may have asbestos in the compound.
If you’re unsure where to start, we recommend exploring asbestos removal in Calgary services to understand how testing fits into the larger safety plan.
What to Do If Asbestos Is Found
If testing confirms asbestos is present, the next step depends on its location and condition. In some cases, we can encapsulate it if it’s in good condition and not at risk of disturbance. However, if it’s damaged or in an area that will be renovated, removal is often the safest option.
We always advise against disturbing it yourself. For example, scraping off a popcorn ceiling without proper precautions can create a major health hazard. Likewise, using regular shop vacuums or dust masks isn’t effective in preventing fiber spread. Specialized vacuums and full containment are required.
Removing asbestos involves sealing off the area, creating negative air pressure, and following strict disposal protocols. In short, it’s not a DIY job. We follow regulations set by Alberta’s occupational health and safety standards to ensure everything is handled safely and legally.
Hidden Asbestos Risks You Might Not Expect
Most homeowners expect asbestos in ceilings or insulation, but we’ve seen it in more unexpected places too. For example, boiler wrap, duct insulation, and even old caulking have tested positive. That is to say, homes don’t have to look outdated to contain asbestos.
Likewise, many homes with partial renovations may contain a mix of safe and hazardous materials. You might have a freshly painted wall layered over old drywall compound that contains asbestos. This makes partial demolition especially risky without testing. We’ve also encountered cases where fireplaces were renovated without removing the asbestos board behind them.
If you’re unsure whether an area might contain asbestos, it’s always best to ask. For peace of mind, don’t wait until work has started to get it checked. That’s when most exposure happens.
Who Needs Asbestos Testing the Most
While any homeowner in an older Calgary house should consider testing, certain situations make it even more important. Firstly, if you plan to do renovations, testing before starting is critical. Further, if you’ve already started and noticed materials that could be asbestos-containing, stop and get an assessment immediately.
Additionally, landlords and property managers should take asbestos seriously. In rental properties, tenant safety becomes your responsibility. Likewise, anyone buying an older home should consider testing part of their inspection checklist. Finding asbestos after you’ve moved in often means delays, costs, and health concerns that could have been avoided.
We offer easy ways to contact us for professional advice on how to arrange a safe assessment. Whether it’s for a single room or an entire home, we’ll help make sense of the next steps.
Tips to Stay Safe Until Removal Happens
If asbestos is found but cannot be removed right away, there are a few ways to stay safe. Firstly, avoid touching or disturbing the area. Do not vacuum or sweep it, as this spreads fibers into the air. Secondly, limit access to the space. For instance, if asbestos is in your attic insulation, don’t store or retrieve items there until removal is done.
Moreover, we suggest sealing doors or vents near the contaminated area with plastic sheeting to prevent fiber migration. In some cases, temporary encapsulation with specialized sealant can reduce short-term risk, but this must be done by professionals.
Above all, do not cut, drill, or scrape any suspicious materials. The fibers are too fine to see and can remain in your home’s air for a long time if disturbed.
Realistic Cost Expectations and Timeframes
Homeowners often ask about cost and how long the process takes. It varies depending on the type of material and the size of the space. Testing typically takes a few days to complete and receive lab results. As for removal, smaller jobs can be done in one to two days, while full-home abatement projects may take a week or more.
Costs depend on material type and complexity of access. For example, removing pipe insulation in a crawl space costs more than removing a small patch of drywall. We’re always transparent with pricing, so you know what to expect before work begins.
Planning ahead helps. Therefore, if you think asbestos might be present, schedule a test well before your renovation is set to begin. That way, there are no delays.
