Drennan did a great job when they came to mitigate our radon. They were very professional and explained everything well.

We had a great experience initially when we used Drennen to install our radon mitigation. Then 18 months later when we had to troubleshoot after a roof replacement they were so kind and helpful. Couldn’t recommend more!

Drennen installed radon mitigation in our home. The guys were courteous, professional and knowledgable at a competitive cost. I would recommend them to anyone needing to address radon issues.

Drennen Custom Contracting did an incredible job. They were friendly, warm, and understanding, and they took my concerns very seriously. They worked with me to determine the best place to implement my radon mitigation system, and took a ton of care to install it out of the way. My initial radon results are still pending, but a cheap radon sensor is indicating that my radon is resolved completely. Please consider them for your radon mitigation needs!

Service has been excellent from estimate to completion of installation. Seth and his crew showed up on time, hit the ground running, were extremely professional and thoroughly cleaned the site when finished. Seth kept me informed throughout, explained how he would find the best location(s) for the installation, involved me throughout and ultimately gave me excellent information and advice so that I could choose the installation location that worked best for us. Highly recommend.

Their tech was friendly and professional, very efficient. He replaced the faulty fan and re-wired the system in less than an hour. Thank you Drennen for great service!

We had Drennen provide radon mitigation for our mountain home and the results were excellent. As owners, we appreciated how the company and crew listened to our requests as to how they could work around existing structures for the installation and still provide the necessary protection. They also discussed our options for the installation and how to minimize any associated outside fan noise given the solitude of the mountain setting (the end result was indeed very quiet). We also felt more comfortable knowing that the crew and company have major roofing experience as they installed the exhaust pipe up through the roof to again minimize associated noise. I can 100% recommend Drennen for its people, quality installation and cost.

We have absolutely loved working with Drennen! They made the radon installation process such a breeze that we didn’t have to worry about a single thing. Plus with being in the middle of closing they made it super easy to have the installation done with the buyers in the home already. Pricing was very reasonable and by far the best installation plan out of all the companies we checked with.
Thank you so much for all your work! We will continue recommending your services to others.
