Frequently Asked Questions
How much does radon testing cost in Pennsylvania?
Professional radon testing in Pennsylvania typically costs $150 to $300. Short-term tests (48 hours) are standard for real estate transactions. Long-term tests (90+ days) provide a more accurate annual average. The PA DEP also offers free DIY radon test kits to Pennsylvania residents through their website.
Why is radon testing so important in Pennsylvania?
Pennsylvania has some of the highest indoor radon levels in the United States. The PA DEP estimates that about 40% of homes exceed the EPA's recommended action level of 4 pCi/L. Every county in the state has homes with elevated radon. The PA DEP and EPA strongly recommend testing every home, regardless of location.
Are radon testers required to be certified in Pennsylvania?
Yes, Pennsylvania requires radon testers to be certified by the PA DEP under the Radon Certification Act. Certified testers must complete approved training, pass an exam, and follow PA DEP testing protocols. For real estate transactions, only a PA DEP-certified tester's results are accepted by lenders.
What happens if my home has high radon levels?
If radon levels exceed 4 pCi/L, the EPA recommends installing a radon mitigation system. The most common approach is sub-slab depressurization, which uses a fan and pipe to vent radon from beneath the foundation to the outside. Mitigation in Pennsylvania typically costs $800 to $1,500 and reduces radon levels by up to 99%.
When should I test for radon in Pennsylvania?
Test when buying or selling a home, after major renovations that alter the foundation, if you've never tested, or if your last test was more than 2 years ago. Testing is best done during the heating season (October through March) when windows are typically closed and radon levels tend to be highest.
