A lot of the radon phone numbers you find for York County ring at a call center that sells your name to whoever pays for it. The Radon Enforcer is the opposite of that.

Radon in York County PA, by the Numbers
If you’re wondering whether this is worth the call, here’s what the state’s data says about York County

A Note on How This List is Put Together
This list isn’t static, and it isn’t for sale. Companies get added when the research supports it, and they get removed if they close, lose certification, or draw a pattern of serious complaints. For each one, we look for Pennsylvania DEP certification, since that’s a legal requirement for anyone performing radon testing or mitigation in this state, not just a nice-to-have. Beyond that, we look at what a homeowner would want to know before hiring: how long the company has been around, what customers say about the install and the follow-up, and whether it backs the work with a written warranty. Use the list as a starting point, then check the DEP number yourself and get the quote in writing.
If you’re weighing radon testing for the first time, or you already have a number back from a test and aren’t sure what it means, what radon mitigation actually involves is worth a read before you make any calls. If you want to understand the certification requirement in more detail, what PA DEP certification actually means breaks that down too.

Questions About Hiring a Radon Company in York County
Is radon a problem in York, PA?
Yes. York County is EPA Zone 1, and PA DEP’s test data shows basement averages around 10 pCi/L in both York and Hanover, more than double the action level. The limestone and shale under the county give soil gas easy paths into homes, and two houses on the same street can test very differently. Radon By York Zip Codes
How much does radon mitigation cost in York, PA?
Most standard sub-slab systems in York County run $800 to $1,500. Historic stone foundations, finished basements that require opening walls, and tight ground that needs more than one suction point push the cost higher. Fan replacement later on runs $250 to $500. Read More About Costs
Does a radon contractor in Pennsylvania need to be certified?
Yes. Anyone testing or mitigating radon for pay in Pennsylvania must hold current PA DEP certification. National credentials like NRPP do not count on their own, and neither does a home improvement contractor number. Ask for the DEP number and check it against the state’s directory. Read More
How does a radon mitigation system actually work?
A fan pulls soil gas from beneath the foundation through a sealed PVC pipe and vents it above the roof, so the pressure under the slab is lower than inside the house and gas flows to the pipe instead of your basement. A properly installed system typically cuts radon by 50 to 99 percent. Read More
My new home has a radon pipe. Does that mean I’m protected?
Not necessarily. Most builder-installed pipes are passive rough-ins with no fan, and in a Pennsylvania winter that usually isn’t enough. Test your air. If it’s over 4.0 pCi/L, a certified mitigator can add a fan and seal the slab, typically for $300 to $600. Read More
Do I have to disclose radon when selling a house in Pennsylvania?
You have to disclose what you know. Pennsylvania’s seller disclosure form asks about hazardous substances, including any known radon test result or mitigation system. You aren’t required to test before listing, but most buyers will test during the inspection period, so knowing your number first is the stronger position. Read More About This
Know a company that should be on this list?
If you run or have hired a radon mitigation company in York County that deserves consideration, get in touch and let us know. Companies are looked at directly, and being suggested is not the same as being listed. Homeowners with questions about a test result or a quote are welcome to reach out too.
