Pricing
What does radon work actually cost in Windsor-Essex?
No mystery, no upsell. Below are the typical price ranges for radon testing and mitigation in Southern Ontario, based on Health Canada guidance, the Take Action on Radon program, and current 2025–2026 pricing from C-NRPP certified contractors across the region.
Typical price ranges
Three steps. Three price points.
Most homes in Windsor-Essex move through one or two of these stages. You only pay for what your home actually needs.
DIY Test Kit
$30 – $60
one-time
Lowest-cost way to find out if you have a radon problem.
- Alpha-track or charcoal long-term detector
- Minimum 91 days of measurement (Health Canada protocol)
- Lab analysis and emailed results
- Best deployed October – April
No professional setup or interpretation. You place it, you mail it back.
Professional Test
$150 – $300
per home
C-NRPP certified placement, calibrated devices, and a written report.
- On-site assessment of your foundation type
- Calibrated long-term or short-term device
- C-NRPP certified protocol
- Written results with clear next-steps recommendations
- Required for many real-estate transactions
Short-term real-estate tests (4–7 days) are typically priced at the higher end.
Full Mitigation System
$2,300 – $3,800
installed, most Windsor-Essex homes
Active soil depressurization (ASD) — the gold-standard fix.
- Site inspection and custom system design
- Sub-slab suction point(s) through your foundation
- Sealed PVC piping routed outside
- Quiet, energy-efficient continuous radon fan
- U-tube manometer to monitor performance
- Post-mitigation radon test to verify the result
- Workmanship guarantee
Older homes, large basements, crawlspaces, or sub-slab obstructions can push pricing higher — we'll quote precisely after a site visit.

What changes the price
Why two homes on the same street can quote differently
Foundation type
A poured-concrete basement with an accessible sump is the easiest scenario. Block walls, multiple slabs, finished basements, or crawlspaces add labour and materials.
Number of suction points
Most Windsor-Essex homes need one suction point. Larger floor plans, additions, or homes with a poorly connected sub-slab gravel layer may need two — adding roughly $400–$800.
Pipe routing
Running the radon stack up through an interior chase looks cleaner but takes more labour than an exterior wall route. We'll show you both options.
Fan model
A standard quiet inline fan is included. Homes with very high starting radon levels or restrictive sub-slab conditions may need a higher-static-pressure fan ($150–$300 upgrade).
Sealing & finishing
Sealing floor cracks, the sump cover, and the slab-to-wall joint is part of every install. Restoring drywall, paint, or finished ceiling tiles is quoted separately if needed.
Crawlspaces
Crawlspaces almost always require a sealed polyethylene membrane in addition to ASD. Expect $500–$1,500 above a standard basement install, depending on size.
Cost in context
How radon mitigation compares to other home upgrades
| Project | Typical Windsor-Essex cost | Health impact |
|---|---|---|
| Radon mitigation system | $2,300 – $3,800 | Removes the #1 cause of lung cancer in non-smokers |
| New high-efficiency furnace | $4,500 – $8,500 | Energy savings, comfort |
| Roof replacement (asphalt) | $7,000 – $14,000 | Weather protection |
| Basement waterproofing | $3,000 – $15,000 | Prevents water damage |
| Whole-home humidifier | $700 – $1,500 | Comfort |
Radon mitigation is one of the most affordable major home-health upgrades — and it's the only one that directly protects your family from a known carcinogen.
FAQ
Common pricing questions
Do I need to test before I get a mitigation quote?+
Yes — a long-term radon test (minimum 91 days) confirms whether you actually need mitigation and tells us how aggressive the system needs to be. We won't install a system without a confirmed test result.
Is there a government rebate for radon mitigation in Ontario?+
There is no province-wide rebate program in Ontario as of 2026. The federal Canada Greener Homes program does not currently cover radon mitigation. Some private insurers and employer wellness programs offer partial reimbursement — ask your provider.
What does the radon fan cost to run?+
A typical mitigation fan draws 40–90 watts continuously. At Windsor-Essex electricity rates, that's roughly $5–$12 per month — about the same as a single LED bulb left on 24/7.
How long does a mitigation system last?+
The PVC piping and sealing should last the life of the home. The fan typically lasts 10–15 years and is a $150–$400 replacement when it eventually fails.
Does mitigation affect home resale value?+
In most cases yes — a documented mitigation system with a post-install test result below 100 Bq/m³ is increasingly viewed as a positive disclosure, especially in Windsor-Essex where buyer awareness of radon is growing.
Can I install a mitigation system myself?+
It's legal but strongly discouraged. An incorrectly designed system can fail to lower radon, or worse, create back-drafting issues with combustion appliances. C-NRPP certification exists for a reason.
