Radon Mitigation in York, PA — Guaranteed Below 4.0 pCi/L
York County is an EPA Zone 1 radon area, and most basements we test here come back above the 4.0 pCi/L action level. We design and install sub-slab depressurization systems for York homes in a single day, with a post-mitigation test included and a written guarantee on the result.
A York County Radon Company, Not a National Call Center
York PA Radon Mitigation is a local crew that does one thing: gets radon out of homes in York County. We don't do home inspections on the side, we don't sell water softeners, and we don't route your call through a national dispatch line. When you call (717) 899-9148 you get a certified mitigator who has worked in the limestone belt around York, the slate country down toward Delta and Peach Bottom, and the red-shale ground north of the city toward Dover and Etters.
That geology matters. York County sits on the Piedmont carbonate belt — limestone and dolomite under the central plain — with the Peach Bottom slate belt to the southeast and Triassic red shale toward the Gettysburg basin. All three produce soil gas, but they don't produce it the same way, and a system that works on a poured slab in a Manchester Township subdivision is not the same system you need under a 1920s stone-foundation rowhome in the city. We diagnose the foundation and the ground before we quote, not after.
Why · choose · us
Why Choose Us
There are two national radon franchises and a handful of home inspectors selling mitigation in York. Here is what is different about working with a dedicated local mitigator.
We diagnose before we quote
Pennsylvania rules require a visual inspection before a bid, but many companies quote from a phone script. We do a communication test under the slab to find out how well air moves through the fill beneath your home, which tells us whether one suction point is enough or whether a York County block-wall basement needs a second tap.
Sized for York County soil, not a national average
Limestone ground in East York, Springettsbury and Manchester is porous and usually needs modest fan power. The dense, fractured slate in southern York County and the tight red shale near Dover can require higher-suction fans. We carry both on the truck so you get the right fan the first time.
Post-mitigation test on every install
A pipe and a fan don't prove anything. We run a follow-up test after the system has operated for 24 hours and give you the written result. If it's not below 4.0 pCi/L — and we aim for under 2.0 — we adjust the system at no cost.
Clean, quiet, code-compliant installs
Schedule 40 PVC, sealed slab and wall penetrations, a sealed sump lid with a radon-resistant drain where needed, a U-tube manometer, a system label, and an exhaust that terminates above the eave line and away from windows. That is what the DEP expects and what a home inspector will look for when you sell.
Real-estate deadlines respected
If a buyer's radon test came back high and the contingency clock is running, tell us the date. We can usually quote within a business day and install within the week across York County.
Straight pricing
Most York homes fall between $900 and $2,000 for a standard active system. We tell you what drives the price — foundation type, number of suction points, fan size, routing — so a quote is a number you understand, not a mystery.

How · it · works
What to expect, start to finish
1. Review your test result
Send us the number from your test kit, home inspection or continuous monitor. Anything at or above 4.0 pCi/L should be mitigated; the EPA suggests considering it between 2.0 and 4.0. If you haven't tested, we can run a 48-hour continuous monitor test first.
2. On-site diagnostic visit
We inspect the foundation, sump, crawl space, slab cracks and floor-wall joint, then drill a small test hole and measure sub-slab pressure and airflow. This tells us where the suction point goes and how big the fan needs to be. You get a written quote on the spot.
3. One-day installation
We core the slab, excavate a suction pit, run sealed PVC through the basement or garage to an exterior or attic-mounted fan, seal every entry route we can reach, and terminate the exhaust above the roofline. Most York County homes are finished in four to six hours.
4. Post-mitigation test and guarantee
After the system runs for at least 24 hours we place a follow-up test. When the result is below 4.0 pCi/L you get the report, the system label and manometer reading, and our written guarantee. Retest every two years or after any major renovation.
