  • Coletta Radon Systems was the most professional company I've ever had install anything on my property. In today's generation it's nice to see companies that still pride themselves on their work and customer relations. Thank you Coletta Radon. - J. Starks, Epping, NH

    Absolutely amazing. Thank you guys for coming out so quickly and helping with our sump pump. The changes you made to our old setup have made a world of difference. We finally have a dry basement! Thank you Coletta! - A. Murphy, NH

  • Who knew I had so much harmful gas in my house. I really appreciated all your knowledge about radon and your taking the time to help me better undertand my risks and my options. I can sleep better at night knowing my children are not breathing in that terrible gas anymore.

    I haven't dealt with a lot of radon companies in my life, thankfully, but my experience with Coletta Radon was second to none. Your service was professional and your attitude was friendly, I will definitely call you again if anything else arises.

  • Best in the business, bottom line. Coletta was the second company I called regarding my radon and thank god I did. The first company, who shall remain nameless, wanted to charge me 30% more and gave me false information. It's good to know there are still some honest folks out there. Thanks guy. - B. Tomlin, Haverhill, MA.

    Radon is a scary thing the more you learn about it, but thankfully you guys helped me understand how to deal with it. The house just feels safer knowing that we have proper ventallation now. Thank you so so much. - Helen, Hampstead
