Radon Testing & Mitigation in Nanaimo, BC
Getting radon testing and mitigation done in Nanaimo is mostly about sequencing — the right assessment first, the right trade second, the right paperwork filed at the end. We run that sequence for you.
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 British Columbia
British Columbia frames this under the BC Building Code. 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 Nanaimo properties
Nanaimo has its own compliance texture: the harbour city’s older downtown rentals sit under active property standards enforcement, and Island buyers routinely commission oil tank scans on pre-1970 lots.
In Nanaimo 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
Here is how the engagement typically runs for Nanaimo properties:
- 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
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.
My neighbour tested low — am I fine?
No. Radon varies house to house on the same street depending on soil contact, foundation cracks and pressure dynamics. Only your own test answers it.
Who enforces radon testing and mitigation requirements in Nanaimo?
Day to day, enforcement in Nanaimo runs through the municipal officials (building, fire prevention, by-law) with the municipal building department as the provincial authority behind them under the BC Building Code. Our local partners deal with both routinely.
