Asbestos, mould and restoration services in Markham
Asbestos testing, mould remediation and water-damage restoration in Markham — Unionville, Markham Village, Thornhill and the newer communities.
What we see in Markham
Markham pairs two preserved nineteenth-century main streets — Unionville and Markham Village — with a very large modern build-out that began in earnest in the 1980s and hasn't really stopped. There's also a substantial corporate and commercial belt along Highway 404 and Woodbine. The heritage streets and the late-1970s and early-1980s subdivisions are where our asbestos work is concentrated; the rest of the city is mostly water, mould and renovation support.
Asbestos likelihood here
Mostly newer, with well-defined older pockets. Markham Village, Unionville and Thornhill hold genuinely historic housing, and there's a band of 1970s–80s construction that can still contain asbestos in finishes and adhesives even though it looks modern.
This is context from the age of the local housing stock, not a finding about your property. Only a laboratory test on a sample can confirm whether a material contains asbestos — so nothing should be cut, sanded or removed on the strength of a guess.
Common jobs in this area
Heritage-street renovations
Houses on and around the old main streets are old enough for plaster, original insulation and layered finishes, and they're renovated often.
Late-1970s and early-1980s homes
The easiest ones to misjudge. They can look contemporary but still predate the full phase-out, so floor levelling compound, adhesives and textured finishes are worth testing before a gut.
Finished-basement flooding
Common across the newer subdivisions, where a failed sump, appliance or supply line soaks framing behind finished walls.
Commercial tenant turnovers
Office and flex units along the 404 corridor need a survey before a strip-out if the building is old enough.
Getting the work done here
Straightforward almost everywhere: private driveways, garage access and space for a bin. Heritage-district properties are the exception — tighter lots, conservation considerations, and sometimes restrictions on what can be staged out front.

Do I need an asbestos test before renovating in Markham?
If the building predates roughly 1990 and the work will cut, sand or break into walls, ceilings or floors, yes — a laboratory test on a sample is the only way to know what is being disturbed. In Ontario, asbestos work is classified Type 1, 2 or 3 under O. Reg. 278/05, and which type applies depends on that result. Nothing should be removed on the strength of a guess.
