John and his team did an amazing job of reducing our radon from 10+ to 0.3 in only a few days. From the beginning of this process, the initial phone call, to the final install everything was explained and transparent. The day of the install the weather was questionable however the team arrived on time. I was concerned with our newly refinished flooring and all the salt and sand that the workers could bring in but John was on it covering the floor in a drop cloth. The job was done quickly and absolutely no mess was left behind. I would 100% recommend this company for all radon mitigation! A wonderful group of people ⭐⭐⭐⭐⭐
We had a great experience working with John. Great communication. Patience for all of my questions and concerns. Knowledgeable, flexible, and a get 'er done attitude. I highly recommend him.
Very pleased with the work John and his team did for me. They were prompt, efficient and clearly knew what they were doing. At first he estimated that I would need a more extensive system but once he was able to get to work realized that he could do a simpler system so we actually came in under the estimate.
John is very professional, honest, and helpful. Installed a radon in water system and went above and beyond in the process. 10/10 would recommend to family and friends!
Excellent service. They were prompt and efficient. They also came in below their original quote. I am also very pleased at how quiet the motor sounds, as it was a concern of mine. I highly recommend them.
