What Is Radon Mitigation?
Radon mitigation reduces radon gas levels inside your home to safe levels. The most effective method is Active Sub-Slab Depressurization (ASD) — drawing radon from beneath your foundation and venting it safely outdoors.
A professionally installed ASD system reduces radon levels by 80–95% in most homes. Our systems routinely achieve below 30 Bq/m³.
What We Install
Sub-Slab Depressurization
The gold standard. A pipe through the concrete slab + fan system draws radon out from beneath the floor and vents it above the roofline.
Sub-Membrane Depressurization
For crawlspaces with exposed soil. A specialized membrane and fan system seals and depressurizes the crawlspace to prevent radon entry.
Sump Pit Sealing
Airtight sump covers prevent radon from entering through open sump pits — code-required in new BC construction for radon safety.
Foundation Crack Sealing
We seal all accessible cracks, cold joints, and floor-wall joints with approved materials to improve overall system efficiency.

How It Works
Diagnostics
We perform sub-slab pressure testing to determine the ideal suction point and correct fan sizing.
Installation
We drill, route pipes, install the fan, and seal visible cracks — typically in one day.
Verification
A post-install test confirms your radon levels are below 200 Bq/m³. Results guaranteed.
Our Guarantee
We guarantee every mitigation will bring your radon levels below Health Canada's 200 Bq/m³ action level. Our systems typically achieve under 30 Bq/m³. If levels don't drop below 200 Bq/m³, we return at no charge.
1-year labour warranty. 5-year manufacturer warranty on all fans.
Post-installation test included on every job. Results within days.
Systems run 24/7 automatically. Visual pressure indicator for easy monitoring.
