How we make money

Radon Compass is free to use. To pay for it, we may earn money when you buy something or request quotes through the site. Money never changes the data we show.

Right now

The site doesn't earn anything yet: there are no affiliate links, ads or paid referrals. We'll list each way we earn money here as it's added.

Our rules

• Test results, costs and other figures come from the public sources named on each page. No one can pay to change them.
• We say when a link earns us money, next to the link, not only on this page.
• Paid placements are labeled as sponsored or featured, and never ranked as if they weren't.
• Our advice is the same whether or not we earn from it. The EPA recommends testing every home, and we recommend a certified professional for any fix.
