Radon Mitigation for York County, PA Homes
Radon has no smell, no color, and no warning light. We find out what your house is doing, pull the gas out from under it, and test again so you can see the number drop.


Meet David, the Man Behind The Radon Enforcer
David Brockelhurst has spent his whole working life inside other people's houses. First in water and fire restoration, where a homeowner's worst day was where his day started. Then years running jobs and crews for a painting company. Then managing radon mitigation projects right here in York County.
He started The Radon Enforcer because of what he kept seeing on Google: radon companies with no truck, no address, and no one who ever shows up. Some are just websites that sell your phone number to whoever pays. Reach out here and you get David, a straight answer about your number, and a plan written in plain English.
- You talk to the owner, not a lead seller
- Free same-day estimates, Monday to Saturday
- A follow-up radon test after every system we install

What Makes The Radon Enforcer Different
Radon work happens under your floor and inside your walls. You should know exactly who is doing it.
A real company you can find
A street address in Red Lion, the owner's name on the website, and an email that goes straight to him. We don't buy leads and we don't sell yours.
We read the house before we drill
A 1920s brick row home in Hanover and a new poured basement in Springettsbury need different systems. We check the foundation, the sump, and every addition first.
We prove the number came down
Every system gets a follow-up radon test. We also show you how to read the gauge on the pipe, so you'll know if the fan ever quits.
Straight talk, no scare tactics
Radon is a real lung cancer risk, and it's also a very fixable problem. We explain your result calmly and tell you what it takes.

Radon in York County Is a House-by-House Problem
About 40% of Pennsylvania homes tested come in above the EPA’s 4 pCi/L action level, according to the Pennsylvania Department of Environmental Protection. York County sits right in that picture. That does not mean your house is high. It means you have no way to know without a test.
Two houses on the same street can come back with very different numbers. One might sit on tight clay, the other on broken rock that lets soil gas move freely. One has a sealed sump, the other has an open pit in the corner. The only number that matters is the one from your house, which is why we start every job with a real result, not a guess.
If you haven’t tested yet, start with radon testing. If you already have a high number, radon mitigation is the fix.
Where Radon Gets Into York County Homes
York County has houses from almost every era, and each one lets radon in a little differently.
- Stone foundations in the old boroughs, like Red Lion, Hanover, and Glen Rock. Rubble stone walls leave hundreds of small gaps, and some still have dirt or thin concrete underfoot.
- Block basements in the postwar ranches and Cape Cods. Hollow concrete block can carry soil gas up inside the wall itself.
- Split-levels with a basement, a slab, and a garage slab side by side. One suction point doesn’t always reach all three.
- Farmhouses with additions built decades apart. A stone basement, a crawlspace under the kitchen addition, and a slab family room is a common York County mix.
- New poured basements in subdivisions. They look tight, and they can still test high.
Why a Tight New House Can Still Test High
Heat rises. In a closed-up house during a York County winter, warm air leaks out the top floor and the house pulls replacement air in low, including soil gas through the slab. Kitchen and bath fans pull the same way. The Pennsylvania DEP is clear that radon shows up in new homes and old ones, drafty homes and sealed ones, with or without basements.
That’s why we don’t sell anyone a system based on the age of the house. We sell it based on the test.
Silent, Not Scary
The EPA ranks radon as the leading cause of lung cancer in people who have never smoked. For smokers, radon and smoking together raise the risk far more than either one alone. That’s worth taking seriously.
It’s also worth keeping in perspective. The risk builds over years of breathing it, and the fix is routine work: a fan, some sealed pipe, and a follow-up test. You don’t need to panic. You need to test, and if the number is high, you need a system that’s built for your house. That’s the whole job, and it’s the only thing we do. If you want to know who you’d be dealing with, meet David first.


From Your Number to Proof It's Fixed
Here is the order we work in, from your first call to the test that proves it worked.
You reach out
Call, email, or send the form. Reach us during business hours and we'll set up your estimate that same day.
We look at the house
We check the foundation types, the sump, any crawlspace, and where the pipe and fan can go without wrecking a finished room. Then you get a written price.
We install the system
Suction point, sealed piping, a fan outside the living space, a sealed sump lid if you have one, and a gauge you can read.
We test it again
A follow-up radon test shows the level after the system is running. You keep the result for your records or your buyer.
Facts You Can Verify Before You Hire Us
A fake radon company can't fill in this list. We can.
What York County Homeowners Ask Us
What radon level is too high?
The EPA says to fix your home at 4 picocuries per liter (4.0 pCi/L) or higher, and to think about fixing it between 2 and 4. There is no known safe level, so lower is better. If your test came back at 4.0 or above, a mitigation system is the standard fix.
We failed the radon test and we close next week. Can you help?
Yes. Call or send the form during business hours and we'll set up your estimate that same day. Tell us your closing date up front so we can plan the install and the follow-up test around it. Your realtor will want that follow-up result in writing.
Is it safe to stay in the house until the system goes in?
Radon risk comes from breathing it over years, not days. A high test means get it fixed, not move out tonight. If it helps you feel better while you wait, spend less time on the lowest level of the house.
Can't I just seal the cracks in my basement?
Sealing helps a system work, but the EPA says sealing alone hasn't been shown to lower radon much or reliably. Radon comes through joints, pipe openings, and the concrete itself. An active system that pulls soil gas out from under the slab is what brings the number down.
Do you work on stone basements, crawlspaces, and finished basements?
Yes. York County has all three, often under the same roof. Stone walls and dirt floors need extra sealing, crawlspaces get a sealed membrane with suction under it, and in finished basements we plan the pipe route so it doesn't cut through your family room.
What does a radon mitigation system cost?
It depends on the house. The foundation type, how well air moves under the slab, how many separate slabs or crawlspaces there are, and where the pipe has to run all change the price. We give you a written price after we see the house, and the estimate is free.
What towns do you cover?
All of York County. We work from Red Lion and regularly cover Hanover, Dover, Dillsburg, Spring Grove, Shrewsbury, New Freedom, Glen Rock, Delta, Wrightsville, Springettsbury Township, and West Manchester Township, plus the towns in between.
