Montreal Neighborhoods We Serve
Montreal’s mold risks vary by neighborhood. Plateau triplexes hide moisture behind century-old plaster. West Island waterfront homes battle humidity from the lake. South Shore suburbs deal with spring thaw basement floods. Our mold inspection and mold removal teams know what to look for, block by block.
Island of Montreal
Plateau Mont-Royal
Century-old triplexes and duplexes with hidden moisture behind original plaster walls. Attic mold is common; we use thermal imaging to confirm before opening anything.
Westmount
Luxury stone homes where basement humidity and estate-era foundation cracks drive most mold issues. Detailed reports accepted by high-end insurers.
Outremont
Mixed-era residential housing. Advanced moisture detection finds problems early, often before visible signs appear.
NDG (Notre-Dame-de-Grâce)
Multi-unit buildings with bathroom and ceiling mold in shared spaces. We coordinate with building managers and tenants.
West Island & West Montreal
West Island
Waterfront homes from Pointe-Claire to Beaconsfield, where proximity to water drives humidity and mold patterns. We have inspectors who know the area well.
Pointe-Claire & Dorval
Suburban homes with basement and attic seasonal issues. Spring thaw and summer humidity create recurring problems.
Lachine
Industrial-adjacent and older residential buildings. Moisture intrusion and crawl-space mold are the most common findings here.
LaSalle
1960s–70s housing stock with concrete basements and crawl-space risks. Our team knows the typical failure points.
South Shore & Laval
Longueuil
South Shore hub with suburban bungalows and basement moisture from the area’s water table. We serve most of Longueuil within same-day.
Saint-Lambert & Brossard
Mixed-era residential with HVAC-driven mold risks in newer builds. We do both inspection and air-quality testing.
Laval
Suburban homes across Chomedey, Fabreville, and Sainte-Rose. Carpet mold, crawl-space moisture, and attic condensation expertise.
Old Montreal & Downtown
Historic stone buildings and high-rise condos. HVAC condensation and shared-system mold are our specialty here.

Air Quality Testing in Montreal
Visual inspection catches what you can see. Air quality testing catches what you can’t. When someone in your home has unexplained allergy symptoms, when you’ve had a flood, or when you’re buying a property with a “damp” smell you can’t pin down — airborne spore testing tells you whether there’s a hidden problem, and how serious it is.
Who Needs It
- Homes with unexplained allergy or asthma symptoms
- Post-flood and water damage assessments
- Real estate transactions (buyer due diligence)
- Rental disputes and tenant health complaints
- Commercial spaces with occupant complaints
- Homes with persistent musty smells but no visible mold
What We Test
- Airborne spore counts (indoor vs outdoor baseline)
- Species identification (Aspergillus, Stachybotrys, Cladosporium, etc.)
- HVAC duct sampling for distributed contamination
- Surface swab testing for visible suspect growth
- Basement and crawl-space air quality
- Bathroom and high-humidity zones
What You Get
- Accredited lab results, typically within 48 hours
- Plain-language interpretation of what the numbers mean
- Bilingual report (English or French)
- Insurance-ready documentation with methodology notes
- Remediation recommendations prioritized by risk
- Baseline data for post-remediation clearance testing
Air quality testing pairs naturally with the Complete Assessment tier above — you get the visual inspection, the lab data, and the bilingual report in one package. Read more about how air sampling works.
Bilingual Service & Quebec Compliance
Montreal’s regulatory landscape is different from the rest of Canada. French-language reports aren’t a nice-to-have — they’re what insurers, lawyers, and the Régie du logement expect. Our team delivers Quebec-specific expertise, in the language that works for your situation.
French Inspection Reports
Complete inspection reports available in French for insurance claims, legal proceedings, real estate transactions, and regulatory filings. Rapports complets d’inspection de moisissure en français, prêts pour les assurances et les procédures juridiques.
BNQ 3009-600 Aligned

Our inspectors speak English and French fluently. Comfortable with tenant disputes, landlord documentation, real estate transactions, and health-symptom investigations — in whichever language makes the situation clearest for your family.
If you need a test d’air pour moisissure, an inspection de moisissure Montréal, or a full bilingual report for a landlord-tenant dispute, we’ve handled it before. Call (514) 700-6838 or book a free virtual assessment.
Montreal Mold Problems We’ve Solved

Third-floor tenant reported recurring allergy symptoms in a century-old triplex near Mont-Royal. Previous owner insisted the building was mold-free.

Frequently Asked Questions
How quickly can you detect mold in my Montreal home?
Certified inspectors can identify visible mold immediately during the visual assessment. Hidden mold detection using thermal imaging and moisture meters typically takes 2–3 hours on-site. Laboratory results for species identification and spore counts are available within 24–48 hours, and your full bilingual report is delivered shortly after that.
What makes Montreal properties more vulnerable to mold?
Montreal’s climate creates near-perfect mold conditions year-round. Spring thaw causes basement flooding, summer brings high humidity, and winter condensation from heating systems drives hidden moisture behind walls. Historic buildings in areas like Plateau Mont-Royal and Old Montreal add another layer of risk — aging roofs, century-old plaster, and legacy foundation systems all trap moisture in ways newer builds don’t.
Do you provide bilingual services and French reports?
Yes. Our inspectors are fully bilingual in English and French. All inspection reports are available in French to meet Quebec requirements for insurance claims, legal proceedings, and regulatory compliance. Rapports d’inspection de moisissure disponibles en français.
What’s the difference between air testing and visual inspection?
Visual inspection identifies mold and moisture problems you can see — stains, growth, water damage, active leaks. Air quality testing detects airborne spores from hidden contamination you can’t see, whether behind walls, inside HVAC ducts, or beneath finished flooring. For most comprehensive assessments — especially real estate transactions or post-flood situations — we recommend combining both methods.
Are your inspectors certified for Quebec regulations?
Our team holds IICRC, IAC2, NAMP, ACAC, InterNACHI, and NORMI certifications. We understand Quebec’s BNQ 3009-600 standards for mold remediation and the RBQ registration requirements that apply to Quebec contractors. All inspections meet provincial regulatory standards, and reports are formatted to be accepted by Quebec insurers and legal proceedings.
What happens if you find mold — do you handle removal too?
Yes. We provide certified mold removal services directly, alongside inspection and testing. For small problems under 10 square feet, some careful DIY cleanup may be appropriate, and we’ll tell you if that’s the case. For anything larger — or anything involving Stachybotrys (black mold) or HVAC contamination — we coordinate professional remediation with our certified remediation partners and follow up with post-work clearance testing.
