"If you are looking for radon mitigation or radon testing dont look beyond clay radon services.I was amazed by his service the way he explain me the whole process and then sending out the contract having all the warannty details and other info.And on the work perspective he made it look so simple and flawless that i was not even knowing that something was going on in my basement.He work one step ahead and seal all the basement cracks plus took care of replacing sump pump lid too and sealing it. From exterior also he install it in such a way that I dont even feel that something extra has been installed in my house. Good job.And on the price I don't think anyone can beat him on price with the qaulity of service he is providing.cheers."
