Independent verification testing after radon mitigation system installation — confirms that the installed system has reduced indoor radon below the EPA action level of 4 pCi/L.
The final confirmation step. Industry best practice (and Pennsylvania standard) is verification testing within 30 days of system activation and again at 2 years.
Post-Mitigation Verification Testing for Pennsylvania homeowners is performed by an NRPP-certified, PA DEP-certified partner contractor from our network. Pennsylvania Radon Experts routes your project request to the appropriate certified specialist within 4 business hours of submission.

Pennsylvania post-mitigation verification testing typically costs $100 – $250 all-in. Final pricing depends on home size, foundation type, and accessibility for venting or test deployment. Our partner contractors provide free on-site assessments and itemized written quotes within 48 hours of the site visit.
Pennsylvania's average indoor radon is 8.5 pCi/L — the highest in the United States. 2 in 5 Pennsylvania homes test above the EPA action level of 4 pCi/L. The cost of mitigation is typically recovered through reduced long-term health risk, increased home value, and compliance with Pennsylvania real estate disclosure law.
Yes. Pennsylvania's cold winters intensify radon entry through the stack effect — heated indoor air rising creates negative pressure in basements that pulls soil gas into homes at higher rates than warmer climates. That makes post-mitigation verification testing especially important in Pennsylvania homes — winter readings are typically 30–50% higher than summer readings.
Our partner contractors install systems engineered for year-round Pennsylvania conditions: fans rated for sub-zero operation, piping rated for thermal cycling, and post-mitigation verification testing performed under closed-house conditions for accurate baseline readings.
If your radon test came back above the EPA action level of 4 pCi/L, mitigation is the EPA-recommended response. Most Pennsylvania homes test elevated.
Pennsylvania Real Estate Seller Disclosure Law (68 Pa. C.S. § 7301-7315) requires sellers to disclose known radon test results. Buyers often request testing and mitigation contingencies. Closing-timeline projects accommodated.
Pennsylvania home inspections increasingly include radon testing. Pre-purchase mitigation negotiation with sellers is common. We coordinate test + quote within the inspection window.
Radon Resistant New Construction (RRNC) builds passive mitigation into the foundation during construction — far cheaper than retrofitting later. Pennsylvania builders increasingly include this.
Apartments, condos, and townhomes require unit-by-unit testing and building-scale mitigation. HUD-funded properties have mandatory compliance requirements.
Pennsylvania law (Title 28 Pa. Code § 27.31) recommends schools test to test all ground-contact occupied spaces every 5 years. Our network includes specialists certified for school and public-building radon work.
