Radon Gas Abatement
Tim did an absolutely outstanding job installing the radon mitigation system in my home. From start to finish, he was professional, knowledgeable, and incredibly easy to work with. He arrived exactly when he said he would, communicated clearly throughout the entire process, and took the time to explain everything in a way that was easy to understand. What really stood out to me was the quality of his work and attention to detail. The installation was done neatly, efficiently, and with obvious care and expertise. On top of that, Tim was extremely polite, respectful of my home, and genuinely pleasant to talk to. His pricing was also very fair and reasonable, especially considering the level of service and craftsmanship he provided. It is rare to find someone who combines professionalism, punctuality, honesty, and high-quality work so well. I would highly recommend Tim to anyone needing a radon system installed. I couldn’t be happier with the service and the results!

Very skilled and experienced technician who worked despite snow out of doors to install the system for our protection. rates fell over a day to expectations. he caulked all the cracks in the cement floor of my shop which was the source of the leak of radon gas. Charge for the labor was reasonable He had experience with installing gas mitigation in Ryan Homes where we live

Tim Stoll is a true craftsman: he responded quickly to my Angie request in person with a competitive price. He explained what he would do, why and finished on schedule. My basement is 40 yrs old, but he was able to find to provide a perfect solution that mitigated my radon levels to 25% of code limit. I recommend him for your project if you want a guaranteed enduring solution.
