If you have a home in Calgary that was built before 1990, there’s something important you need to know before you touch your popcorn ceiling.
That rough, textured surface, also called a stipple ceiling or acoustic ceiling, was common in Canadian homes from the 1950s to the late 1980s. Many of the ceiling texture products back in the day had asbestos in them. It was added for better fire resistance, durability and sound absorption.
Asbestos is one of the most dangerous health hazards within older Calgary homes today. And the danger is not in having it; it is in disturbing it not knowing it is there.
In this guide, we’ll cover what Calgary homeowners need to know before starting any popcorn ceiling removal, repair or ceiling texture smoothing project.
Why Asbestos Was Used In Popcorn Ceilings
Asbestos is a naturally occurring mineral fibre that was widely used in construction for decades due to its fire-resistant and insulating properties. It was cheap and tough and efficient.
According to JSE Labs, a certified asbestos testing lab, popcorn ceiling products manufactured before the late 1970s often contained 1% to 10% asbestos.
In 1977 the U.S. Consumer Product Safety Commission (CPSC) banned asbestos in new spray-on ceiling products. Canada also instituted similar regulatory restrictions. But stocks of asbestos-containing products already on the market were not immediately recalled, meaning that in some cases they continued to be used in construction into the early 1990s.
As a result, many homes built or renovated in Calgary between 1950 and 1990 may still have original popcorn ceilings that contain asbestos.
Which Homes in Calgary Are at Risk?
The short answer: Any home built before 1990 should be assumed to have asbestos until tested.
The periods of major residential development in Calgary correspond directly to the era of asbestos. If you live in a neighbourhood that saw a lot of building in the 1960s, 1970s and 1980s – like many of the older inner city communities, established suburbs and many bungalows in NW and SW Calgary – chances are popcorn ceilings are still intact.
Calgary Restoration, a certified asbestos abatement contractor, says here are some signs:
- Your home was built or renovated before 1990
- The ceiling has never been touched since it was built in the first place
- The texture is thick, rough and very bumpy – typical of spray on material of the time
- The ceiling is starting to crack, chip or show water staining
Important: You cannot visually identify asbestos. Popcorn ceilings with asbestos are indistinguishable from popcorn ceilings without asbestos. Visual inspection tells you nothing. The only way to know for certain whether asbestos is present is to have it laboratory tested by a professional.
Why Asbestos Is Dangerous in Popcorn Ceiling
Asbestos that is in a completely intact and undisturbed condition is generally considered low risk. The danger arises when the material is disturbed – because that releases microscopic fibres into the air.
Popcorn ceilings are considered a friable material, meaning they can crumble or break apart with very little force. Even minor contact – such as installing a light fixture, hanging something from the ceiling, sanding, or scraping – can be enough to release asbestos fibres.
When airborne, asbestos fibres are invisible to the naked eye. They can stay in the air for hours and are easy to carry through the HVAC system to other parts of the house. They will not be removed by regular cleaning, such as vacuuming and wiping.
Long-term breathing in of asbestos fibres is associated with:
- Mesothelioma (a rare and aggressive cancer of the lung lining)
- Asbestosis (scarring of lung tissue)
- Lung cancer
These diseases have a latency period of 10 to 50 years, according to Mesothelioma.com (last updated March 2026). That means someone exposed in a 1990s do-it-yourself ceiling scraping project may only now be seeing health consequences.
The same source also published a documented case study of a woman who lived with worsening asbestos popcorn ceilings for 30 years. Over time, water damage caused the ceiling to fall apart. By the 1990s she had lung cancer and asbestosis.
Legal Requirements for Handling Asbestos in Alberta
If you live in Calgary, and your home was built prior to 1990, you are directly affected by asbestos regulations.
Under Alberta regulations,
- All homes built before 1990 must have professional asbestos testing performed before any renovation or removal work can legally begin.
- If testing confirms the presence of asbestos, provincial law requires hiring a licensed asbestos abatement professional. Homeowners are not legally permitted to perform DIY removal of asbestos-containing materials, regardless of the quantity.
- All asbestos waste must be double-bagged and sealed and taken to designated areas of approved Calgary landfills. Standard residential waste services won’t take it.
Non-compliance carries serious consequences. According to Calgary’s Popcorn Ceiling Removal resource (March 2025), homeowners who fail to follow Alberta’s asbestos regulations may face fines of up to $50,000 and could be held liable for health issues affecting workers or future occupants.
How the testing process works
Testing your popcorn ceiling for asbestos is a straightforward process when carried out by a professional. A certified Environmental Testing Technician will:
- Seal and contain the sampling area to prevent fibre release
- Wear full protective clothing, including a disposable suit and respirator
- Cut a small sample of the ceiling texture, typically 1–2 square centimetres
- Send the sample to an accredited laboratory for analysis
- Provide a certified written report confirming whether asbestos is present and at what concentration
Do not try to take a sample yourself. When you scrape the ceiling without the proper protective equipment and containment the fibres are released directly into your living space.
There are a number of certified environmental testing services in Calgary. Professional sample & lab analysis usually takes 3-7 business days for test and results.
Your Choices After You Test
Once you have a certified test result, you have three primary options:
1. Leave It Alone (If Not Damaged)
If the ceiling tests positive for asbestos but is completely intact with no cracking, chipping or water damage, the safest short-term option may be to leave it alone. An undisturbed asbestos ceiling will not emit fibres.
However, this is only acceptable if you are not planning any renovation, the ceiling is in excellent condition and you will keep a regular eye on it for any signs of deterioration.
2. Encapsulation
Some homeowners choose popcorn ceiling restoration instead of full replacement when the existing ceiling texture is still structurally sound.
Encapsulation is the process of applying a special sealant or thick paint to the asbestos ceiling that binds the fibres in place and prevents them from being released.
This is a band-aid. This method only works if the ceiling surface is smooth, whole and dry. Encapsulation doesn’t get rid of the asbestos – it just cuts down the risk of fibre release. If the ceiling is ever sanded, drilled or otherwise disturbed at a later date, the asbestos risk reappears.
This is the usual option for rental properties or for homes where finances are tight and renovation is not on the cards.
This is where popcorn ceiling restoration and professional ceiling texture smoothing become important after safe asbestos removal.
3. Professional Removal (Best for Most Calgary Home Owners)
The safest and most permanent solution is to hire professionals for popcorn ceiling removal which Calgary homeowners can trust. That completely removes the asbestos risk and gives you the ability to modernise your ceiling texture, refinish, or do any other upgrade you want.
Licensed abatement contractors adhere to a rigorous process:
- The room is completely sealed off with plastic sheeting
- Negative air pressure equipment keeps fibres from escaping
- Workers are in approved respirators and full protective gear
- All material is wet when removed to reduce fibre release
- Asbestos waste is double bagged, sealed and taken to an approved disposal site
- After removal, air quality testing is performed to make sure the space is clean before the area is opened
Once the asbestos-containing material has been removed, your drywall ceiling is repaired, smoothed and prepped for a fresh modern finish – flat paint, knockdown texture or some other modern look.
Ceiling Texture Smoothing and Refinishing: The Process After
After the asbestos is removed, popcorn ceiling restoration and ceiling texture smoothing come into play.
Many of Calgary’s popcorn ceiling era homes have drywall that was never finished to a high standard – the textured coating was specifically applied to hide imperfections.
Once removed, the drywall underneath may show:
- Nail pops
- Exposed tape joints
- Cracks
- Irregular surfaces
- Water damage stains
Professional ceiling texture smoothing creates a clean, modern finish and improves the overall appearance of your ceiling. For rooms with intense ambient or raking light, a Level 5 drywall finish is recommended – the highest standard available, where even the smallest surface imperfections become visible under such conditions.
From there, you can select your preferred ceiling finish:
- Flat smooth ceiling is the modern standard; it maximisees light reflection and works with any interior design style
- Many Calgary homeowners also choose popcorn ceiling refinishing using modern asbestos-free materials for a cleaner updated appearance.
- Popcorn ceiling refinishing – for homeowners looking to get a similar look with modern, asbestos-free materials (often found in rental properties or to match neighboring ceilings)
Bottom Line for Calgary Homeowners
If your home was built before 1990 and has original popcorn ceilings, the only responsible first step before any ceiling work is to have the ceilings tested professionally for asbestos.
This is for your health, your family’s health and your reputation in the eyes of the law as a home owner. It also includes any contractor who works inside your home.
The good news is that once the testing is done and the asbestos is properly dealt with, popcorn ceiling removal is a pretty quick renovation with a big visual pay-off in Calgary. Ceiling texture smoothing also improves lighting reflection and makes rooms feel larger, brighter as well as more contemporary.
Calgary Popcorn Ceiling Removal (March 2025) shares that homes with popcorn ceilings typically sell for 3–5% less than comparable homes with modern ceilings, and 78% of Calgary homebuyers request ceiling upgrades during purchase negotiations.
That’s an important number with where Calgary home values are at today.
