Radon mitigation & testing in Nashua, NH

Buying or selling a home in Nashua

In Nashua, radon often comes up for the first time during a home inspection. This page focuses on getting through that process calmly.

Radon during a Nashua home sale

1. Test correctly. NH DHHS describes real-estate testing with two devices side by side and an averaged result. (NH DHHS)
2. Read the number against the EPA guideline. At 4 pCi/L or higher, the EPA recommends fixing the home. (EPA)
3. Get a written mitigation quote quickly. Buyers and sellers often negotiate a credit or a seller-installed system. A quote with a post-mitigation test included gives both sides something concrete.
4. Confirm certification. NH requires national certification for radon-in-air mitigation installers. (NHDES)

If you’re the seller

Installing a system before listing can remove a surprise from the inspection period. Keep the post-mitigation test report for buyers.

If you’re the buyer

Ask whether an existing system has a recent post-mitigation result and a working fan (most have a pressure gauge called a manometer). If the house uses a private well — less common inside the city, more common in surrounding towns — consider a water test as well.
