Montréal
An independent Laval lab for Montréal homes, condos and buildings. Send or drop off a sample, or book an at-home visit anywhere on the Island. Results in 24–48 hours.
Local · In-house
Our lab is in Laval, a short drive from the Island of Montréal, and every sample is analyzed there by our own specialist, not shipped to a third-party lab. That is how results come back in 24–48 hours with a report that shows micrographs of your own sample.
Montréal homes bring their own questions: damp basements, older plexes, condo units after a water leak. We test and report; we do not sell remediation, so you get an independent reading.
Areas we serve : the Plateau, Rosemont, Villeray, Côte-des-Neiges, NDG, Verdun, Outremont, Ahuntsic, the West Island and the rest of the Island of Montréal.
How it works
Step 1
Collect a sample yourself, or book an at-home visit anywhere in Montréal.
Step 2
Drop-off box in Laval (3780 boulevard de la Concorde Est), open 24/7, or ship from anywhere in Québec.
Step 3
A specialist-verified report with annotated micrographs, in English or French, typically within 24–48 hours.
Results describe the air or surface sampled, at the spot and time it was taken. They are a screening and preliminary assessment, not a medical diagnosis, a certification or a building-safety determination.
FAQ
How much does a mold test cost in Montréal?
Samples you collect yourself: $50 per sample, with results typically in 24–48 hours. At-home assessment: $500. Our specialist comes to you, at your home or building, so you don't have to go anywhere. You choose one package: air microscopy (spore traps, compared with an outdoor reference and analyzed in our Laval lab) or air chemistry (VOC, formaldehyde, CO₂, air humidity, fine particles and surface moisture readings). Want both? Add the second package for $250 ($750 total). Air-chemistry readings are screening-grade measurements, not laboratory chemical analysis. We serve Montréal, Laval, the North Shore and the South Shore.
Do you come to my home in Montréal?
Yes. A specialist visits your home or building, takes air and surface samples with an outdoor reference, and analyzes them in the Laval lab. We also serve Laval, the North Shore and the South Shore.
How fast are results?
Typically 24–48 hours after the sample arrives at our Laval lab.
Can a tenant or condo owner order a test?
Yes. Many requests come from tenants and condo owners after a leak or a musty smell. The report describes what was found in the air or on the surface at the time of sampling and explains next steps.
Do you also remove mold?
No. DétectAir only tests, so our results carry no conflict of interest.
