Radon Mitigation in Stewartstown, PA
Radon Help for Stewartstown Homes
If you live in Stewartstown, your home sits in one of the highest radon areas in the country. All of York County is in EPA Radon Zone 1. PA DEP test records put the average York basement near 10 pCi/L, more than twice the EPA action level of 4 pCi/L.
Stewartstown is a small borough in southeastern York County, close to the Maryland line. Rural homes nearby often use private wells, so a water test may be worth adding. Radon levels can swing a lot from one house to the next, so the only way to know your number is to test. Keystone Radon Mitigation tests, fixes and re-tests homes in Stewartstown and across York County. Call (717) 714-3616 to get started.

We handle every step, from the first test to the last re-test.
How Radon Mitigation Works in Stewartstown
Radon is a gas that rises from the rock and soil under your home. You can't see it or smell it. The Surgeon General calls it the second leading cause of lung cancer in the United States, after smoking. The good news is that a radon system can bring most homes to 2 pCi/L or below.
Most Stewartstown homes get a sub-slab system. We seal a pipe into the floor, run it up above the roof and add a quiet fan. The fan pulls radon from under the house before it can get inside. Crawl spaces get a sealed plastic sheet with a suction point under it.
Most installs take one day. The follow-up test starts at least 24 hours after the fan turns on, and you get the before and after numbers in writing. Call (717) 714-3616 to book.
Radon Testing in Stewartstown
Every fix starts with a test. A short-term test runs 2 to 7 days, and a long-term test runs more than 90 days for a better yearly average. If you already have a result from a home inspection or a hardware store kit, send it to us and we'll tell you what it means.
If your home uses a private well, ask about a water test too. Radon in well water escapes into the air when you shower or run the tap. The EPA says to test the air first, since breathing radon is the bigger risk.
