How a radon system works
The standard fix is called sub-slab depressurization. It runs on a small, quiet fan, and it's the method certified installers use most.
- A pipe draws gas from the soil under your basement floor
- A fan keeps it moving out of the house
- It vents above the roofline, where it disperses

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.
I'm selling and failed the radon test. How fast can it be fixed?
Put your closing date in the quote form so your deadline is clear. Most systems can be installed in a day or less once the work is scheduled.
