How Radon Mitigation Works in York, PA
The most common system pulls radon from under your house before it can get inside, and lets it out above your roof. It's done with a pipe and a small fan.
A Small Hole in the Floor
A certified company makes a small hole in your basement floor, down to the soil and gravel underneath.
A Pipe to Above the Roof
A pipe is sealed into the hole and runs up the inside or outside of your house.
A Radon Fan
A fan on the pipe pulls radon out from under the floor. It runs all the time.
Radon Goes Into the Open Air
The radon leaves the pipe above your roof, where it spreads out into the air.

Radon Testing After Mitigation: What Pennsylvania Law Requires
In Pennsylvania, the company that installs a radon system must make sure your home is tested afterwards. PA DEP says the test must be done within 30 days of the install, but no sooner than 24 hours after the system is running, and the rules say it must last at least 48 hours. DEP also recommends an independent follow-up test, by an independent tester or by you, so there's no conflict of interest. Read the rule (PA DEP: Pennsylvania Consumer's Guide to Radon Reduction)
1
System Goes In
The company fits the pipe and fan and switches the system on.
2
Test Within 30 Days
No sooner than 24 hours after the system is on. Your installer arranges the test, or you book an independent certified tester.
3
Check Your Result
Compare your number with EPA's levels above. If it's still 4.0 or higher, talk to your installer.
How to Choose a Radon Mitigation Company in York, PA
Check their PA DEP certification, whether they've worked on homes like yours, their reviews, their guarantee and warranty, how they handle the test after the install, and where they'll put the pipe and fan. Not every company does the job the same way, so it's worth comparing a few.
1
PA DEP Certification
Make sure they're certified by the state for mitigation, not only testing. Every listing shows each certification and its number.
2
Experience With Homes Like Yours
Ask if they've worked on homes like yours: your foundation (basement, slab, crawlspace or a mix), a finished basement, or a private well.
3
Reviews
Read what other customers say about the work and how the company treated them. Listings show Google reviews where there are any.
4
Guarantee and Warranty
Ask what result they promise and how long the system and fan are covered.
5
Retest After Install
Pennsylvania rules say the home is tested after mitigation. Ask if it's included in the price, or book an independent tester yourself.
6
Where the Pipe and Fan Go
Ask if the pipe runs inside or outside, and where the fan will sit.
