Radon Testing & Mitigation in Levis, QC
If you own or manage property in Levis, radon testing and mitigation is one of those obligations that stays invisible right up until an inspector, insurer or buyer makes it urgent.
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
Jurisdiction matters: in Quebec, the Quebec Construction Code (Chapter I, Building) governs, and the power to inspect, approve or prosecute rests with the municipal building department. We scope every job against their current requirements.
Radon Testing & Mitigation for Levis properties
What makes Levis specific: Lévis pairs commuter subdivision growth with a historic riverside core, and RBQ contractor licensing governs all significant work.
In Levis we handle this for private landlords, property managers, condo and strata boards, commercial tenants, and homeowners who just received a requirement they did not expect.
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
We keep the sequence simple:
- 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.

Frequently asked questions
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.
What radon level requires action?
Health Canada recommends remediating above 200 Bq/m³ — within 2 years at 200–600, within 1 year above 600. There is no “safe” floor; many owners mitigate below 200 for occupied basements.
Who enforces radon testing and mitigation requirements in Levis?
In Levis 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.
