What radon level needs fixing?
The EPA action level is 4.0 pCi/L, and Pennsylvania DEP recommends a reduction system at or above it. The EPA also suggests considering a fix between 2 and 4 pCi/L, since no level is completely safe.
Does Pennsylvania require radon testing?
No state law requires homes to be tested, but DEP recommends testing every home. Many buyers ask for a radon test during a sale.
Does the installer have to be certified?
Yes. Pennsylvania law requires professional radon testers, mitigators and labs to be certified by DEP.
Can I install a system myself?
DIY kits exist, but a system installed wrong may not lower radon or can cause other problems. A certified mitigator also provides paperwork that home buyers trust.
