What Our Customers Say About Our Radon Services

Adam was very responsive and his installation team did a great job. Top notch work. Follow-up service and questions were also excellent!

Angela T.

This company is wonderful to work with. They put a radon system in for my daughter and then came and tested my home for free.

Adam O.

Our experience was great throughout the entire process. The system has been installed and levels are down substantially.

These guys are great. Highly recommend! Mitch and David explained everything to me. We found a great place to vent the system through the garage and now the levels are below 1.0 pCi/L.

Kathy K.

A-1 was so professional and easy to work with. The system was installed fast and the clean up was outstanding. I strongly recommend them for radon mitigation.
