Test Came Back High? Here's What Happens Next.
If your radon test in York, PA came back at 4 pCi/L or higher, the EPA says to fix your home. A radon mitigation system is the fix. It pulls radon from the soil under your house and sends it outside, above the roof, before it can build up indoors.
Most York homes get a system called sub-slab depressurization. We drill a small hole through the basement floor or slab, seal a pipe into it and connect a fan. The fan runs all the time and keeps the air under your floor at a lower pressure than the air in your home. Radon follows the easy path into the pipe and out.
Most radon mitigation system installation jobs in York take one day. The EPA says today's systems can bring most homes to 2 pCi/L or below. We re-test after every install and give you the result in writing.

What Every Radon System Installation Includes
A good radon system is more than a fan on a pipe. Here is what goes into each install.
A Pressure Test Before We Drill
We check how air moves under your slab before we pick a spot. This tells us if one suction point is enough or if your home needs two.
A Sealed Suction Point
We dig a small pit under the slab, set the pipe and seal it tight to the floor. Open cracks and gaps near the pipe get sealed too, so the fan pulls from the soil and not from your basement.
Pipe Vented Above the Roof
The pipe vents above the roofline, away from windows and doors. It can run inside through a closet or garage, or outside along a wall.
An Inline Radon Fan
The fan sits outside your living space, in the attic, garage or on an outside wall. That keeps it quiet and helps it last.
A U-Tube Manometer and Labels
This small gauge on the pipe shows the fan is pulling air. We mark the starting reading on it. The fan's breaker and the system also get labeled.
A Re-Test After Install
The post-install test starts at least 24 hours after the fan turns on and no later than 30 days. You get the before and after results in writing.
Radon Systems for Every Kind of York Home
York County has stone basements, slab homes, crawl spaces and mixes of all three. Each needs a slightly different plan.
Basement Homes
This is the most common setup in York County. A single suction point through the basement floor handles most basements. Big basements or floors with footings in the middle may need a second point.
Slab-on-Grade Homes
Homes with no basement sit on a concrete slab. The system works the same way. The pipe often runs through a closet or the garage to reach the roof.
Crawl Space Homes
Bare dirt in a crawl space lets radon in freely. We lay a heavy plastic sheet over the soil, seal it at the walls, and pull air from under the sheet. This is called sub-membrane depressurization.
Homes With a Sump Pit
An open sump pit is a direct path from the soil into your basement. We fit a sealed, clear lid so you can still see the pump.
New Construction and Passive Systems
Some new York homes are built with a passive radon pipe but no fan. If a test after move-in comes back at 4 pCi/L or higher, the EPA says a fan can be added to the pipe. We can turn a passive system into an active one, often in a few hours.
Radon Mitigation System Installation Cost in York, PA
Most radon mitigation systems in York cost between $875 and $2,200. Where your home lands in that range depends on the foundation, the size of the home and how the pipe has to run.

| Two suction points or a large home | Middle to high end of the range |

Radon Mitigation System FAQ
How long does a radon system installation take?
Most radon mitigation systems in York homes go in within one day. Homes with a crawl space or more than one foundation type can take a little longer. The follow-up test starts at least 24 hours after the fan turns on, so final results come a few days after install day.
Does radon mitigation work in a crawl space?
Yes. We cover the dirt floor with a heavy plastic sheet, seal it at the walls and pull air from under the sheet with a fan. This is called sub-membrane depressurization. It works the same way as a basement system, with the plastic sheet acting like the concrete floor.
How long does a radon mitigation system last?
The pipe and seals can last for decades. Radon mitigation systems generally last between 10 and 30 years, depending on the setup and upkeep. The fan is the part that wears out. Most quality radon fans last 5 to 12 years, and a new one can be swapped in quickly.
Will I hear the radon fan?
Most owners barely notice it. The fan sits outside your living space and makes a low hum when it is sized right. If it gets loud or starts to rattle over time, it needs a check.
