Aaron Woodfield was a pleasure to work with. He inspected my house for radon, gave me a reasonable quote and resolved the issue expediently, ahead of schedule and under budget. He is very professional, hard working and is very knowledgeable. I recommend him for anyone who needs a property reviewed for radon.

Alan Erickson

These are the radon guys you’re looking for. I had high radon levels in the crawlspace and measured the level at 9 in a bedroom. After adding an exhaust system to the sump pit, the bedroom level dropped to less than 1. Just as Aaron predicted.

Matt Carson

Not just competitive pricing, but in my case, half the price. Other companies wanted to charge us for stuff that didn’t need to be done. Great job. I would recommend to anyone.
