One of the most common questions we get: how much does radon mitigation cost in BC?

The short answer: most Fraser Valley residential mitigation systems cost between $2,500 and $3,800. Here’s what drives that price and what you get.

What’s Included in a Standard Mitigation

A professional radon mitigation includes:

Pre-installation site visit and diagnostic — Sub-slab pressure field testing to determine the best suction point location and fan sizing
System installation — Drilling, pipe routing, fan installation, exterior exhaust (typically one day)
Sealing — Caulking visible cracks, cold joints, and sump penetrations
Post-installation short-term verification test — Confirms the system is working
Documentation — Before/after readings, system specs, warranty paperwork

What Affects the Price

Factors that increase cost

Multiple suction points — Some homes with poor sub-slab communication need 2–3 entry points
Crawlspaces — Sub-membrane depressurization is more labour-intensive than slab work
Complex routing — Long pipe runs, finished basements, or challenging exhaust paths
In-floor heating — Requires GPR or thermal imaging to avoid hydronic lines
Commercial buildings — Larger footprints require multiple systems

Factors that keep cost down

Simple slab with good sub-slab communication
Direct exterior wall exhaust route
Accessible utility room for fan placement

What About Radon Testing?

Testing is separate from mitigation:

Long-term alpha track test (91+ days): $40–$75 for a DIY kit, or included with professional monitoring
Short-term professional test (96 hours): $200–$350 (C-NRPP certified, includes report)

Is Radon Mitigation Worth It?

Absolutely. Consider:

A standard mitigation costs $2,500–$3,800 — similar to a hot water tank replacement
Systems last 20+ years (fan warranty typically 5 years)
Reduces lung cancer risk from prolonged radon exposure
Increases home value and saleability
Many buyers now request radon testing as a condition of purchase
