Fix a high result
The U.S. EPA recommends fixing your home if radon is 4 pCi/L or higher, and considering a fix between 2 and 4 pCi/L. How mitigation works →
Test the right way
Short-term, long-term and real-estate tests each have their place. New Hampshire residents can also order a free kit from the state. Testing guide →
On a private well?
Radon can also come in with well water. NHDES has specific guidance on when water treatment makes sense. Well-water FAQ →
Why radon matters in southern New Hampshire
- Radon is the second leading cause of lung cancer in the U.S. and is linked to about 21,000 lung cancer deaths a year, according to the EPA. (EPA)
- NH DHHS says New Hampshire’s granite bedrock raises exposure: the state’s estimated average indoor level is around four times the national average of 1.3 pCi/L. (NH DHHS)
- In American Lung Association analysis of 2008–2017 CDC data, Hillsborough County had the most pre-mitigation tests in the state (5,528) and an estimated mean of 5.3 pCi/L — above the EPA action level. (ALA report)
- Testing is the only way to know. A neighbor’s result does not tell you yours. (NH DHHS)
How it works
- Tell us about your home. Town, test result (if you have one), foundation type, and whether you’re on a private well.
- We pass it to a local pro. Your request goes to an independent radon professional who serves your town.
- They contact you. You get answers and, if needed, a written quote. You decide — no obligation.
Before hiring anyone, it’s smart to confirm their certification yourself. Since January 1, 2015, New Hampshire has required radon-in-air mitigation designers and installers to be nationally certified (NHDES); you can look people up on the NRPP site.
