Radon FAQ

Who actually does the work?

Is radon really a concern in Massachusetts?

One estimate (SOS Radon) puts about 650,000 Massachusetts homes above the EPA guideline. Levels vary house by house, so the only way to know is to test.

What level should I worry about?

The EPA recommends fixing at 4 pCi/L or higher and considering a fix between 2 and 4 pCi/L.

Do new homes have radon problems?

They can. Massachusetts requires some radon-resistant construction in new homes in the highest-risk counties, but that doesn’t guarantee low levels, so new homes should be tested too.

Is a test required to sell my house?

How much does a system cost?

Which towns do you cover?
