“I called and got my current radon level and it came in at only 1.6. Happy Days!
Recall that I had previously had levels of 37 and 45 downstairs. You were great to work with. Very thorough in finding the best layout for the extraction holes, explained everything, and worked with my house layout to make the mitigation unobtrusive. Thanks much.”
