Asbestos gets most of the attention when people talk about hazards in older homes, but it is not the only one hiding behind the walls. Lead-based paint was common in Canadian homes for much of the twentieth century, and homes built before the 1980s can still have layers of it under newer coats. For most of the year that paint sits harmlessly. The risk appears the moment a renovation starts sanding, scraping, or demolishing surfaces that contain it.
Why Lead Paint Is Still a Concern in Calgary
Lead was added to paint for durability and colour for decades before its health effects were fully understood and its use in consumer paint was restricted. Many older Calgary homes still have lead paint on window frames, door trim, baseboards, railings, and exterior surfaces, often buried under several newer layers. Intact, well-maintained paint is generally low risk. The danger comes from lead dust and chips created when that paint is disturbed.
Renovation is the classic trigger. Sanding a windowsill, scraping old trim, or demolishing a wall can release fine lead dust that settles on floors, furniture, and surfaces, where it is easily ingested or inhaled, especially by young children.
Who Is Most at Risk
Lead exposure is particularly harmful to young children and pregnant women. Small children are more likely to put hands and objects in their mouths, and their developing bodies absorb lead more readily. This is why timing and containment matter so much during renovations in family homes. Our article on lead paint and young kids and when to act fast at home covers the warning signs and the situations that call for quick action.
When a Renovation Turns Risky
The problem is rarely the paint sitting on the wall. It is the renovation activity that disturbs it. Watch for these higher-risk scenarios in a pre-1980 home:
- Dry sanding or scraping painted surfaces, which creates fine dust
- Demolishing walls, trim, or windows coated in old paint
- Using heat guns or open flame on old paint, which can release fumes
- General renovation dust spreading through living areas
- Disturbing exterior paint that then contaminates soil around the home
If your home predates the 1980s and your project involves any of these, it is worth confirming whether lead is present before you begin. You can learn more about the specific dangers on our lead paint risks in older homes page.
The Safe Approach: Test, Contain, Remediate
Handling lead paint safely follows the same logic as asbestos: identify it first, then control it.
Testing
Confirming whether paint contains lead removes the guesswork and lets you plan the renovation properly. Testing is straightforward and gives you a clear basis for deciding how to proceed.
Containment
If lead is present, the work area should be sealed off, dust controlled, and living spaces protected. This prevents contamination from spreading through the home during the work.
Professional Abatement
For significant disturbance, professional lead paint abatement is the safest route. YYC Asbestos Removal & Renovation offers lead paint abatement alongside its asbestos services, using proper containment and cleanup so that the renovation does not leave hazardous dust behind.
Why Combine Lead and Asbestos Awareness
Older homes that contain lead paint very often contain asbestos as well, because both were common in the same eras of construction. Planning a renovation in a pre-1980 or pre-1990 Calgary home is the ideal time to consider both hazards together. Addressing them in a coordinated way, with one experienced team, is more efficient than discovering each problem separately mid-project.
YYC Asbestos Removal & Renovation is equipped to assess and handle both, which means a single point of contact for the two most common hidden hazards in older homes. That coordination keeps your project moving and your household safe.
Frequently Asked Questions
How do I know if my home has lead paint?
Homes built before the 1980s are the most likely to contain it, often under newer paint layers. Testing is the reliable way to confirm whether lead is present before you disturb any painted surface.
Is it safe to sand old paint myself?
Dry sanding old paint in a pre-1980 home is risky because it can create lead dust. If you are unsure whether lead is present, have the paint tested first and consider professional abatement for significant work.
Can I just paint over lead paint?
Intact paint that is sealed and undisturbed may be stable, but any renovation that scrapes, sands, or demolishes it can release lead dust. A professional can advise whether managing it in place or removing it is appropriate.
Do you handle both lead and asbestos?
Yes. YYC Asbestos Removal & Renovation offers lead paint abatement along with asbestos testing and removal, so both hazards can be addressed by one experienced team.
Renovate Older Homes the Safe Way
A renovation should improve your home, not expose your family to a hidden hazard. If your Calgary home was built before the 1980s, take lead paint as seriously as asbestos before the demolition begins. YYC Asbestos Removal & Renovation can assess and safely address both.
