Straight answers
The three things Markham callers ask first
"Short conditional period."
Same-day sampling plus a 24-hour lab cycle usually clears well inside the window, with the seller's permission to sample.
"Renovation budget depends on the answer."
Exactly why testing first pays: a negative result removes Type 3 containment cost from the quote entirely.
"Attic has grey pebbly insulation."
That is vermiculite — sampled from a sealed access point rather than by crawling the attic.
Thornhill, Unionville, Milliken and Markham Village were largely built between 1955 and 1985, before the 1990s eastern expansions.
We collect and test material. ClearGuard does not sell removal work, keeping the finding independent.

Kitchen remodel never lost a day
Inspector was here the same afternoon, pulled three samples and the lab report landed in my inbox before the crew showed up the next morning.

Straight answer on our popcorn ceiling
1969 ceiling texture and no idea what was in it. The report was plain English with a photo of every sample point, and the $50 came off without me asking twice.

Fast and professional
Booked at nine, sampled by one. They sealed every spot they touched and vacuumed the area before leaving.

Insurance wanted documentation
Our carrier asked for lab documentation after a water loss. The chain-of-custody paperwork was exactly what the adjuster needed.

Good value, quick turnaround
Two-minute phone quote with no runaround. Results back inside a day as promised. Only wish weekend slots were easier to grab.

Peace of mind before demo
We were taking out a load-bearing wall in a 1976 house. Negative result and the written report kept the permit moving.

Honest, zero upsell
They never pitched me removal work. Just testing, results and a clear explanation of what the numbers actually meant.

Patient with a nervous homeowner
I was worried about my kids being in the house. The inspector walked me through containment and what was genuinely a risk.
