Braeden M. was awesome! Super knowledgeable, quick, and clearly knows what he’s doing—he swapped out my equipment and ran a water test without any issues. He’s such a polite young man and handled everything professionally, quickly, and efficiently. What really stood out was how smooth and stress-free he made the whole process—you can tell he genuinely takes pride in his work. Honestly one of the best service experiences I’ve had. Highly recommend!

We had a great experience with Protect Environmental / RAdata. It was easy to get an estimate for our radon system, and Charif did quick, clean work installing it. Rocco finished the job by hooking up the electrical and made sure our breaker was labeled and we knew how to ensure the fan was working properly. System runs quiet and is unobtrusive inside and outside. Would definitely recommend this crew.
Response from the owner:Hi David, Thank you for the thoughtful review and recommendation. We’re glad the estimate process was easy, Charif completed the installation quickly and cleanly, and Rocco made sure everything was connected, labeled, and explained clearly. We truly appreciate your trust in RAdata. — RAdata, a Protect Environmental company

Every individual I interacted with was fantastic, from the office personnel, installer and testers. All appointments are confirmed via text and adhered to. You’re also notified via GPS Tracking when they’re on the way which is especially helpful when service involves an empty house on the market. Highly recommended.
Response from the owner:Hi Ellen, Thank you for such a thoughtful review and recommendation. We’re glad every part of the process, from the office team to the installers and testers, was smooth and reliable. We’re also happy to hear the text confirmations and GPS tracking were helpful, especially for a home on the market. — RAdata, a Protect Environmental company

Rock stars! Dave Letcher and his team did a great job installing a new radon unit. We had such a nightmare with the work done on an old unit and were days before closing on our home. His knowledge of radon systems saves me from having a unit that was not up to code. His team’s installation was flawless. If you want a company that is professional, thorough and honest chose this one. Thanks again ,Dave! You are a true asset to your company
Response from the owner:Hi Lorraine, Thank you so much for the wonderful review and recommendation. We’re glad Dave Letcher and the team were able to step in, install the new radon unit properly, and help give you peace of mind before closing. We truly appreciate your trust and will be sure to pass your kind words along to Dave and the team. — RAdata, a Protect Environmental company

I will give a 5 stars Joe that came to service was excellant and I felt safe with him in my house at this stressful time. As far as the test not being in his truck would have preferred skipping the come back a second time. Think that could have been skipped this year but all done now lets hope we are all well for years to come!
Response from the owner:Thank you so much for the 5-star review, Sue. We are very glad to hear Joe made you feel safe and comfortable in your home, especially during a stressful time. We also appreciate your honest feedback about the missing test and the extra return visit. That is helpful for us as we work to improve the experience. We are glad everything is taken care of now, and we truly appreciate your trust. — RAdata, a Protect Environmental company

Waited a few years to post this to make sure I see consistent results from the radon mitigation system these guys installed and basically this install cut my radon in the basement where my office is by more then half to very safe and acceptable levels. I have a radon counter in my office measuring daily, weekly and long term average and all of those are showing safe levels now for the past nearly two years. The overall process was easy , professional, clean, fast, efficient and affordable. Highly recommended!
Response from the owner:Hi Mark, thank you for taking the time to share this and for the great 5-star review. We’re glad to hear the mitigation system has consistently kept your radon levels in the safe range over the past two years. It’s great knowing the installation made a real difference in your office space. We truly appreciate your recommendation! — RAdata, a Protect Environmental company

Excellent radon mitigation service. They installed an attic fan, sealed the sump pump, added a pressure gauge, and provided a self retest kit to confirm levels were reduced. The person was knowledgeable, supportive, and accommodated our schedule. Everything was handled professionally and on time. We also appreciated the 5-year fan warranty and 1-year labor warranty. Highly recommend for reliable and effective radon solutions. Slightly expensive compared to competitors but worth for the services , permit and warranty provided.
Response from the owner:Hello Simar, Thank you so much for your thoughtful 5-star review! We’re glad to hear the mitigation process met your expectations and that our team was able to provide a thorough, professional installation. Thank you for your recommendation and for trusting us with your home’s safety. – RAdata, a Protect Environmental company
