Buying or selling in Doylestown? Radon timing tips
- Pennsylvania sellers must give buyers a property disclosure statement before an agreement of sale is signed. The Real Estate Commission's minimum form asks whether the seller knows of hazardous substances "including... radon" and whether the property has been tested (49 Pa. Code § 35.335a; 68 Pa.C.S. Chapter 73).
- Sellers aren't required to test, but must not hide known defects (68 Pa.C.S. § 7308).
- Real estate radon tests by certified testers follow DEP anti-tampering rules, including a signed non-interference agreement (25 Pa. Code Chapter 240). Book the test early in the inspection contingency window, because short-term tests run at least 2 days plus lab time.
- If a result is high near closing, ask certified mitigators for written quotes. Buyers and sellers often negotiate who pays for a system.

Questions to ask a mitigator before you sign
- What post-mitigation level do you guarantee, and what happens if the retest is high?
- Who does the follow-up test, and is it an independent certified tester?
- What warranty covers the fan and the work, and is it transferable if I sell?
- Will you seal the sump, cracks or floor-wall joints, and is that in the quote?
- Is a system monitor (manometer or alarm) included so I can see the fan is working?
What a typical Pennsylvania radon system install involves
Most systems use active soil depressurization (EPA Consumer's Guide to Radon Reduction). The installer drills a suction point through the basement slab (or seals a crawlspace with a membrane), runs PVC pipe to an inline fan, and vents the exhaust above the roofline. Then they seal major openings and add a pressure gauge. A follow-up test should confirm the level dropped. PA DEP describes the confirm-then-mitigate steps on PA DEP: Radon in the Home.
