Questions to ask a mitigator before you sign

  • Is a system monitor (manometer or alarm) included so I can see the fan is working?
  • Do you carry liability insurance, and will you put the full scope in writing?
  • What is your PA DEP certification number, and will you show your DEP photo ID? (Certified people must show it on request under 25 Pa. Code Chapter 240.)
  • Will you do diagnostic (sub-slab suction) testing before choosing fan size and suction points?
  • Where will the pipe run (inside or outside), and where will the fan and exhaust go?
  • What post-mitigation level do you guarantee, and what happens if the retest is high?

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.

ItemTypical range (national)

Buying or selling in Greensburg? 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.
