"Radon mitigation is not listed in the business catagories, rather surprising given Colorado's high levels . Armond of NortherColoradoRadon came to the house to give an estimate, the others gave estimate over phone by google maps. He showed up, charged less, did it well, and the radon went down from 9.97 to under 2. After the heavy rains, for some reason the numbers increased, and i am going to get a stronger fan. I highly reccommend this company. Also , get a decent radon detector that gives digital readings such as AirThings."

"All Colorado Radon tackled a particularly difficult radon mitigation that other companies refused to mitigate. They were very thorough and knowledgeable. Most of all, they were successful in reducing radon levels to well below government standards. We would use them again."
