Radon Testing & Mitigation in Brossard, QC
We arrange radon testing and mitigation for property owners across Brossard — matched to the rules that actually apply in Quebec and to trades who work in the area every week.
Radon — the radioactive soil gas — is the second-leading cause of lung cancer in Canada, and the only way to know a building’s level is to measure it. Health Canada’s guideline is 200 Bq/m³; large swaths of the Prairies, interior BC, New Brunswick and pockets of every province routinely test above it. Workplaces are increasingly expected to test under occupational health duties, and daycares in several jurisdictions must.
How it works in Quebec
Quebec frames this under the Quebec Construction Code (Chapter I, Building). In practice, the standards your documentation must meet come from the municipal building department — and meeting them first time is exactly what our partners are for.
Radon Testing & Mitigation for Brossard properties
Local knowledge changes the job. In Brossard, REM-driven tower construction around Quartier DIX30 brings a wave of new buildings into Quebec’s facade, elevator and fire testing cycles.
Typical Brossard clients for this service: landlords answering municipal or insurer letters, buyers in due diligence, condo boards keeping their statutory calendar, and business owners fitting out or renewing leases.
Mitigation that works
Above-guideline results are fixed reliably: active sub-slab depressurization — a sealed suction point and fan discharging above the roofline or per code — typically cuts levels by 80–90%+ for $2,000–$4,000 in most homes. Certified mitigators verify with post-installation testing. New construction in radon-prone areas already ruggedizes for this under the building code’s radon provisions.
The process
The path from enquiry to closed file usually looks like this:
- Tell us the building type, occupancy and whether a transaction deadline exists.
- Approved long-term detectors are placed (or a certified measurement pro attends).
- The lab result determines whether mitigation is indicated.
- A certified mitigator designs and installs the system.
- Post-mitigation testing verifies the reduction and documents it.
One enquiry gets you the requirement mapped, the right Brossard-area specialist matched, and the documentation handled end to end.
Frequently asked questions
Does a radon system hurt resale?
The opposite, increasingly: a documented low result or an installed, verified system is a selling point — the house with the unknown is the risky one.
Do apartments need testing?
Ground-contact and basement units, yes; upper floors test lower but towers with parkades can surprise. Landlords testing proactively hold the strong position with tenants and regulators.
Which authority handles this in Brossard?
In Brossard the front line is municipal — building department, fire prevention, by-law enforcement — backed provincially by the municipal building department under the Quebec Construction Code (Chapter I, Building). We prepare files to satisfy whichever level is asking.
