Radon Testing reviews in Saint Louis

  • I called and asked about installing a mitigation system, as the radon levels were 4.1 pl per million (limit is 4.0). Provider name locked. inquired about features of the basement. He recommended sealing the covers of the two sump pumps in the basement, and sealing the drainage channels and retesting prior to purchasing a mitigation system. He also provided information about how to obtain a free test from the state.

  • My home was for sale and narrowly failed the radon test requested by the buyer.  Provider name locked. was available to promptly come to my home and install a mitigation system that was guaranteed to reduce radon to acceptable levels.  Although I paid the bill, they worked with the buyer to design and install the system in a way that would be the least obtrusive.  The price they charged for their services was reasonable and they were very flexible in working with me and the buyer.

  • We called because we thought the fan had stopped working and to look into the issue of water dripping from the pipes in our garage during the winter. It turns out the fan still worked as the power was turned off. It was good to know that they were honest and stated the fan did not need to be replaced at this time. They determined the reason water dripped from the pipes in the winter was due to having the wrong flange on the roof. They did a good job of fixing it. I can't wait to see if working this winter so I don't have to scrape the ice off my windshield on my car that is in a garage. Note: they are not the same company who put the system in place.
