They did a great job installing our radon mitigation equipment!
I was able to easily contact Adam, initially, and schedule a consultation. Mitch was extremely helpful providing logical suggestions and solutions as he developed a plan. He was able to schedule us within a very reasonable time.
Ryan and his colleague arrived on time, knew exactly what needed to be done, and expertly completed the project in a little over two hours.
I would highly recommend this Company!

Ryan from A-1 Radon was prompt on installation day. He did a great job of explaining what he intended to do and asked for permission to proceed. He was careful and the installation was very neat. He did a great job explaining how the radon remediation system operated and what i had to do to maintain it. Adam in the home office also explained very plainly what they intended to do and what it would cost. We are very pleased.

Working with Adam and his crew was as easy as easy gets. They were able to come out quickly determine the best course of action to get this resolved install a system for me, even took care of making sure it was placed exactly how I wanted it exactly where I wanted it and took the time to run a full test and show me what to look for if I wanted to inspect it myself. The price was extremely fair and I’m very happy with the service in the product that I received. The radon levels in the house before the system was installed were much higher than I would’ve liked to see them, since the system has been installed, the radon levels have been so low...Working with Adam and his crew was as easy as easy gets.

Couldn’t be happier.

We had A-1 Radon system in our previous two homes. In our current new homes we have been dealing with a mold issue and decided to check the Radon just to be sure and comfortable. As it turns out we had high reading and made our appointment to have a system installed. Notified our neighbors as well. Turns out we all had passive radon piping in our homes but builder didn't mention it to any of us. A-1 Radon is a reputable company in our opinion, we even had a central vacuum in our last place.
You won't regret using A-1 Radon and Vacuum in your home.
