What this site does

Practical radon guidance first. Local quote routing only when you ask.

Lancaster Radon Help was built for homeowners who need a plain-English answer before they talk to a contractor.

This website is intentionally independent. We are not pretending to be a radon mitigation company. If you request help, your information may be forwarded to a local provider serving your area so they can contact you directly.

What Lancaster County homeowners should know

Radon is a naturally occurring radioactive gas that can enter homes through cracks, gaps, sump pits, crawl spaces, floor drains, and other openings in the foundation. You cannot see it, smell it, or taste it. The only way to know your home's level is to test.

A radon mitigation system is designed to reduce the amount of radon entering the living space. In many local homes, that usually means an active soil depressurization system: a pipe, fan, and venting setup that pulls radon from beneath the foundation and vents it above the roofline.

Before requesting an estimate

Gather the test result, test location, foundation type, basement/crawl space details, sump pit information, and any inspection or settlement deadline.

Before hiring anyone

Confirm PA DEP certification, ask where the fan and piping will go, review the warranty, and ask whether post-mitigation testing is included or recommended.
