My neighbor just had her basement tested and needed a DEP certified radon contractor to install a mitigation system. I found one through the state's list, and he explained how radon seeps through soil and can build up to dangerous levels. He measured, sealed cracks, and put in a vent pipe with a fan to pull the gas outside. It's reassuring knowing the work meets state standards for safety.
