What is a safe radon level in York, PA?
The EPA says to fix your home if radon is 4 pCi/L or higher. That is the action level. The EPA also says no level is risk-free, and you may want to fix your home if it reads between 2 and 4 pCi/L. Outdoor air has about 0.4 pCi/L, so no home will ever read zero. Modern systems can bring most homes to 2 pCi/L or below.
Is radon really high in York County?
Yes. York County is in EPA Radon Zone 1, the highest risk group. PA DEP test records put the average York basement near 10 pCi/L, well above the action level. Across Pennsylvania, about 40% of homes tested come in above 4 pCi/L. Levels vary a lot from house to house, so the only way to know your number is to test.
How much does radon mitigation cost in York?
Most radon mitigation systems in York cost between $875 and $2,200. A single-suction system on a basement or slab sits at the low end. Large homes, crawl spaces and homes with more than one foundation type cost more. The fan also adds about $30 to $300 a year to your power bill. We give you a written price after we see your home.
How long does radon mitigation take?
Most systems go in within one day. Homes with a crawl space or a mix of foundations can take a little longer. The follow-up radon test should start at least 24 hours after the fan turns on and no later than 30 days after. You get the before and after numbers in writing.
How do I know if my radon system is working?
Look at the U-tube manometer, the small gauge on the radon pipe. If one side of the liquid sits higher than the other, the fan is pulling air. If both sides are level, the fan has stopped. The gauge can't measure radon, so the EPA also says to re-test every two years and after any fan work.
Can I buy or sell a home with high radon in Pennsylvania?
Yes. High radon is common in York County home sales, and it is fixable. Buyers often ask the seller to install a system or give a credit for one. Sellers can test before listing and fix the problem on their own time. Either way, get a re-test after the install so everyone sees the new number.
Do radon contractors need to be certified in Pennsylvania?
Yes. Pennsylvania's Radon Certification Act says anyone who offers radon testing, mitigation or related services to the public must be certified by the PA Department of Environmental Protection. You have the right to see proof of certification. You can check any tester or mitigator by calling the PA DEP Radon Hotline at 800-237-2366.
Should I test my well water for radon?
If your home uses a private well, a water test is a good idea once your air test is done. Radon in water escapes into the air when you shower or run the tap. The EPA says the risk from breathing radon in air is much larger than the risk from drinking it, so test the air first. If both are high, each has its own fix.
