How to Handle High Radon Levels When Selling Your Home

May 6, 2025      

If you're selling your home (essentially anywhere in Mass.) and discover high radon levels, don’t panic — you can handle it! While radon is a serious health concern, addressing it properly can help maintain your home’s value and keep the sale on track. Here’s how to manage the situation:

1. Understand Radon Risks

Radon is a naturally occurring gas that can seep into your home through the foundation. It’s the second leading cause of lung cancer, but the good news is that radon levels can be lowered with proper mitigation. A high reading doesn’t mean the end of your sale, especially if you handle it proactively.

2. Test for Radon Early

Before listing your home, it’s smart to test for radon. If you find high levels, you can address them early and avoid surprises. A professional radon test gives you an accurate reading, so you’ll know if mitigation is needed.

3. Mitigate Before Listing

If radon levels are high, consider installing a radon mitigation system before you list the home. These systems reduce radon levels and make your home more attractive to buyers. The process is quick, affordable, and helps protect future homeowners.

4. Be Transparent with Buyers

If you’ve already tested for radon, let potential buyers know. Share test results and show that you’re taking steps to address the issue, whether by installing a mitigation system or adjusting the sale price.

5. Provide Documentation

If you've installed a radon mitigation system, keep all relevant documentation, including post-mitigation test results. This transparency builds trust with buyers and ensures they know the issue has been professionally resolved.

6. Radon Disclosure

Check your state’s laws on radon disclosures. You may need to inform buyers about radon levels in the home. If you’ve mitigated, include system details and test results to show buyers that the home is safe.

7. Be Prepared for Negotiations

Buyers may ask for a price reduction if mitigation hasn't been done. Installing a system yourself before listing could help avoid this negotiation and make your home more appealing to buyers.
