Radon testing measures exposure; mitigation reduces it. These five guides explain test duration, $800 to $1,200 installation guidance, foundation-specific systems, maintenance and county radon data.
Radon mitigation in Pennsylvania typically costs $800 to $1,200 per system, according to PA DEP’s January 2026 guidance. Home test kits cost about $20 to $30; electricity and future maintenance add to the running cost.
Read the guide ↗Radon testing measures the concentration in a property. Short-term tests take 2 to 90 days; long-term tests take more than 90 days.
Read the guide ↗An active radon system uses a fan and pipework to collect soil gas beneath a slab or crawl-space membrane and vent it outside. Foundation type determines the collection method.
Read the guide ↗A radon fan runs continuously. The system gauge shows pressure, while a radon test establishes the indoor concentration.
Read the guide ↗Pennsylvania’s EPA map uses three county zones: above 4, 2 to 4, and below 2 pCi/L predicted screening levels. Test the home itself before deciding on mitigation.
