Kitchen gut in a Killarney home, what should be tested first?

If your Killarney home was built before 1990, Alberta OHS bulletin ASB004 says there is a higher risk that some materials used in its construction may contain asbestos. Get a hazardous materials assessment done before any demolition work begins, not after.

What to have tested in a kitchen gut

A pre-renovation survey covers the materials the gut will disturb. In a kitchen, those include:

• Drywall joint compound and plaster (the Alberta Asbestos Abatement Manual adds stipple and acoustic finishes to the list)
• Vinyl sheet flooring and vinyl floor tiles (the Manual notes vinyl floor tiles usually contain about 10 per cent asbestos by weight)
• Ceiling tiles and any textured or stippled ceiling finish
• Pipe insulation on supply or drain lines running through the space
• Duct tape and wrap on any heating ducts

If the home was built before 1960, Health Canada says it probably contains lead-based paint, and exterior surfaces built between 1960 and 1990 may also contain it. Ask the assessor to include a lead check on painted surfaces you plan to sand or strip.

A qualified assessor takes bulk samples and sends them to a lab for polarized light microscopy analysis. Published Calgary-area prices for bulk sample lab testing run $65 to $145 per sample, with packages of several samples costing less per sample. A full pre-renovation hazardous materials assessment is quoted per building; few Calgary firms publish a flat price, so ask each contractor for a written quote.

Do not cut, drill, sand or pry any surface until you have results back. The Alberta Asbestos Abatement Manual notes that joint compound and stipple may not have been mixed evenly, so asbestos content can vary within a single home. A small hole in the wrong spot is not a low-risk task.

Once results are back, the picture becomes clearer. If asbestos-containing material is confirmed, the contractor working in your home is bound by Alberta OHS Code Part 4: they must file a 72-hour notification with Alberta before any work that may release fibres, every worker entering a restricted area must carry a current government-approved Alberta asbestos worker card, and all waste must be stored in sealed, impervious, labelled containers. For disposal in Calgary, asbestos goes to Shepard landfill only, by permit and appointment, at $220 per tonne since February 2026. The City of Calgary also requires an Asbestos Abatement Information Form before it releases a building or demolition permit, so have the assessment report ready when you apply.

Ask for clearance air testing done by a consultant independent of the abatement crew, and confirm which lab will count the samples.

If you want to reach local Calgary abatement contractors directly, the request form on this page sends your details to contractors listed in the Calgary Construction Network directory.

Before you commit to any abatement scope, ask the contractor to show you the 72-hour notification confirmation number so you know the filing was actually made.
