Radon Help for Hanover Homes
If you live in Hanover, 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.
Hanover, in western York County, is known as the Snack Food Capital of the World. Its borough streets have many older homes with stone or block foundations, which often need extra sealing. 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 Hanover and across York County. Call (717) 714-3616 to get started.

How Radon Mitigation Works in Hanover
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 Hanover 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 Hanover
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.
