What Radon Mitigation Costs in York, PA in 2026

York County homeowners ask the same question every heating season: what will a radon system cost?

The Pennsylvania DEP typical range for a standard sub-slab depressurization system in 2026 is $800 to $1,200 installed. That includes diagnostic testing to place the suction point, 3 or 4 inch PVC routing, an inline centrifugal fan with a 5-year manufacturer warranty, a gasketed sump lid, slab crack sealing and a U-tube manometer for monitoring.

Two factors move the price. First, slab access: a finished basement or crawl space adds prep work. Second, fan selection: larger footprints or heavy soil gas loads need bigger fans.

Every system we install includes a post-mitigation retest to confirm levels below the EPA 4.0 pCi/L action level. If your home tests at or above 4.0 pCi/L on a 48-hour charcoal kit, mitigation is the EPA-recommended response.
