Does Home Insurance Cover Radon Mitigation?

Key Takeaways

Homeowners insurance excludes radon mitigation and testing because insurers classify radon as a maintenance issue, not a covered peril.

The US Environmental Protective Agency recommends mitigation for any home testing at or above 4.0 pCi/L.

The EPA recommends testing your home for radon every two years, and radon mitigation systems using sub-slab depressurization can reduce indoor radon levels by up to 99%.

Does Homeowners Insurance Cover Radon Mitigation?

Homeowners insurance does not cover radon mitigation under any standard policy. Radon is a radioactive gas with no color or odor, created by the natural decay of uranium in soil and rock. It seeps into homes through cracks in foundation slabs, gaps around utility pipes and construction joints, and it's present in all 50 states. Both radon testing and mitigation are out-of-pocket costs, and home warranties exclude radon as well.

Radon is the second leading cause of lung cancer in the U.S. and the leading cause among nonsmokers, according to the Environmental Protection Agency. The agency recommends mitigation for any home testing at or above 4.0 pCi/L.

Why Doesn't Homeowners Insurance Cover Radon Mitigation?

A home insurance policy covers sudden and accidental losses from named perils like fire, windstorm, burst pipes and theft. Radon accumulates gradually over months and years, which places it in the same policy category as termite infestations, wear and tear and slow-developing mold.

Radon mitigation is a preventable maintenance, with DIY test kits and professional testing widely available. Since homeowners have affordable detection tools, insurers treat mitigation the same way they treat servicing an HVAC system or repairing a deteriorating foundation.

RADON AND YOUR HOME SALE

If you are buying or selling a home, radon test results may be required during the transaction. Some lenders, particularly for FHA and VA loans, require radon testing before approving the mortgage. If high radon levels are detected, the buyer can negotiate for the seller to install a mitigation system or reduce the sale price. A functioning mitigation system can add value to a home and speed up the closing process.

How to Protect Your Home From Radon

Because homeowners insurance does not cover radon, testing and mitigation fall on the homeowner. These steps reduce radon levels in your home:

1
Test Your Home for Radon Levels
Purchase a short-term charcoal canister test kit from a hardware store or order one from your state radon office. Place the kit in the lowest livable level of your home (usually the basement) for 48 to 96 hours with windows and doors closed. If results come back at or above 4.0 pCi/L, the EPA recommends mitigation. Retest every two years.
2
Hire a Licensed Radon Mitigation Professional
Contact a contractor certified through the National Radon Proficiency Program (NRPP) or the American Association of Radon Scientists and Technologists (AARST). Many states require radon mitigators to hold a state license. Ask for references and a written estimate before work begins.
3
Install a Sub-Slab Depressurization System
The most common residential radon mitigation method involves drilling a suction point through the basement slab, running PVC piping to the exterior and attaching a fan that vents radon gas above the roofline. Most systems are installed in one day and begin working immediately.
4
Seal Foundation Cracks and Entry Points
Caulk visible cracks in basement floors and walls, seal gaps around utility pipes and cover exposed sump pits. Sealing alone does not replace active mitigation but improves the system's performance.
5
Retest After Installation
Run a follow-up radon test 24 hours after the system is operating and again at 30 days. The post-mitigation test confirms the system is reducing radon to safe levels. Keep records of all test results.
6
Maintain Your System Annually
Check the fan indicator gauge or U-tube manometer monthly to confirm the system is running. Replace the fan when it fails, roughly every eight to 10 years. Annual maintenance keeps the system effective.

Is Radon Mitigation Covered in Home Insurance: Bottom Line

Standard homeowners insurance does not cover radon testing or radon mitigation systems. Insurers classify radon as a gradual, naturally occurring hazard that falls under the maintenance exclusion, not a covered peril. Test your home for radon, and if levels exceed 4.0 pCi/L, hire a licensed professional to install a sub-slab depressurization system.

Radon Mitigation & Home Insurance: FAQ

Does any type of home insurance cover radon mitigation?

No standard homeowners insurance policy covers radon mitigation or testing. Radon is classified as a naturally occurring environmental hazard, not a sudden or accidental event caused by a covered peril. Some home warranty plans also exclude radon. The cost of testing and mitigation falls entirely on the homeowner. If a covered peril (fire, windstorm or burst pipe) damages your foundation or destroys an existing mitigation system, the structural repair or equipment replacement may be covered under dwelling coverage, but the radon system installation itself is not.

Will testing my home for radon affect my homeowners insurance rates?

Radon testing alone does not affect your homeowners insurance premiums or appear on your claims history. Only filed claims are tracked through CLUE reports.

How often should I test my home for radon?

The EPA recommends testing your home for radon at least every two years and after any major renovation that disturbs the foundation. If you have a mitigation system installed, retest annually to confirm the system is working effectively.
