Eric with Radon Defense was professional, courteous and very knowledgeable in his expertise. He diagnosed the issue quickly and completed the work (replacing my broken radon fan) very quickly as well. I highly recommend Radon Defense for any radon fan issues.

I highly recommend! Eric is very flexible, punctual and friendly. I had to change the schedule last minute and he was cheerful and easygoing. He is efficient and thorough.

Linda arranged the details and scheduled the work as soon as possible for them and me. Eric, the technician who did the work was amazing. Friendly, knowledgeable, very professional. Was a good experience and I’m glad the repair is finished.

The woman on the phone, Linda, was quick to take down my information and get me on the schedule. She was very professional and efficient. Unfortunately, the installer tried two Radon Fans when he was here, both very noisy. I complained to the company and they corrected the situation with a quieter fan after a few days. Problem resolved.

Radon Defense did an excellent job with replacing my impaired existing system. The team was focused and professional and I really appreciate how they answered all my inquiries in detail, teaching me about the system overall.

They came and were respectful of my space and time. They did a good job with the installation. One area of improvement is in explaining the installation process for plugin vs hardwired fans and the fact that it is best to write a check to avoid credit card surcharge fees.

Ed was great. Professional, courteous, explained everything. He was thorough and timely.

They are the best. They don't connect to the sump pump, which can cause problems down the road. They use a licensed electrician. Caulk all the cracks. The fan they put in is so quiet. They position everything as much out of sight as possible. Their work is top notch.

Great Work!

My house is older and has a tough crawlspace to work in but their team was able to identify and implement a solution quickly and for less than I expected to have to pay. I'm very pleased with the mitigation system and my Radon levels began falling within days. I will continue to use Radon Defense in the future and as a bonus I found a good electrician through them as well.

These guys installed a low profile radon mitigation system and did a terrific job. Our radon in the basement before installation was around 3.8. After installation it’s now 0.4! These guys know what they’re doing! I highly recommend!
