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

  1. Test for radon with a short-term kit or a continuous monitor.
  2. If the home was built before 1978, check for lead in water and be aware of lead paint.
  3. On a private well, run a broad drinking-water panel.
