Pennsylvania DEP certified radon contractor 2

When we bought our old stone house in Pennsylvania, the home inspector said we needed a Pennsylvania DEP certified radon contractor to test and mitigate our radon levels. I found a local guy who's been certified for over a decade and knows the geology of our area. He explained the process, installed the vent system, and made sure our levels were safe. It's peace of mind knowing someone with real expertise handled it, not just a handyman with a test kit.
