The average radon mitigation system costs between $800 and $2,500, depending on your home’s foundation type, layout, location, and required system complexity. Most U.S. homeowners pay around $1,200 to $1,500 for professional installation.
What’s Included in Radon Mitigation Costs?
A professional radon mitigation system typically includes:
- System design and site evaluation
- Labor and materials
- PVC piping and sealing of entry points
- Radon vent fan (with power supply and external venting)
- Post-installation testing to confirm effectiveness
- Warranty and inspection (varies by contractor)
Most systems are installed in 1 day and begin reducing radon levels immediately.
Factors That Affect Radon Mitigation Pricing
| Factor | Impact on Cost |
|---|---|
| Foundation Type | Homes with basements, crawlspaces, or slab-on-grade each require different mitigation techniques. |
| Home Size & Layout | Larger homes or homes with multiple foundation types may need more complex systems. |
| Existing Sump or Drainage Systems | Can reduce installation complexity—or add costs if sealing is needed. |
| Local Radon Levels | Higher levels may require more powerful fans or dual systems. |
| Electrical Access | If electrical work is needed to power the fan, this adds cost. |
| Aesthetic Considerations | Hidden or custom system installations cost more than standard exterior runs. |
How to Save on Radon Mitigation
- Compare certified contractors in your area for competitive quotes.
- Ask about warranties—some companies offer 5- to 10-year coverage.
- Check for local or state grants—some areas offer rebates or financial assistance.
- Bundle with home improvements like basement sealing or insulation.
- Test during home purchase—you may negotiate for the seller to cover mitigation.
Is Radon Mitigation Worth the Cost?
Yes—radon mitigation is a one-time investment that protects your family from a known carcinogen. It also:
- Increases your home’s value
- Makes your home safer for resale
- Helps with real estate transactions in radon-prone zones
- Reduces long-term healthcare risk, especially for children or smokers
The cost of mitigation is small compared to the health risks of long-term radon exposure.
