My radon contractor near me came highly recommended when I bought this old house with a basement. He set up two test canisters in the lowest living area, waited the required days, then mailed them off. His report explained the results clearly and even included a simple sketch of where to seal cracks. Straightforward, no upselling, just honest work.
