I am buying or selling a home
Radon, lead, and well water are the usual testing items in a sale.
Home transactions commonly involve radon, which is a leading contributor to lung-cancer risk, lead in paint or plumbing for homes built before 1978, and a water test when the home is on a private well. Short-term radon kits and mail-in water tests cover most needs. Confirm that any lab you use is accredited.
What to do
- Test for radon with a short-term kit or a continuous monitor.
- If the home was built before 1978, check for lead in water and be aware of lead paint.
- On a private well, run a broad drinking-water panel.
Where to go next
Short-term kits and continuous monitors to check radon, a leading indoor cause of lung-cancer risk.
Mail-in and at-home kits plus certified labs to test drinking and well water for PFAS, lead, bacteria, nitrate, hardness, and more.
