Just had our Radon Mitigation System installed and Guardian tech's were AWESOM! The installation was completed in a very efficient manner and met high quality standards. The technicians were very informative and shared all key information and operational details. any disruption was maintained at a minimum and cleanup was excellent. My wife and I are very pleased with the entire job and would recommend Guardian to any/all new clients.

Very Happy Customers

Chris, Mary Ann, Taylor and the whole team were wonderful.

Very professional, knowledgeable kind and thorough with the radon mitigation process. They worked with us diligently and the installation of the system was super quick and easy. They answered all our questions and provided us with very useful information for the future. They are very used to the process of radon mitigation for a real state transaction so they also provided all the parties with the paperwork needed, avoiding delays or last minute hurdles. I would definitely recommend it to anyone looking to install a mitigation radon system.

So many good things to say about the company. From your first call to Mary Ann, then your first inspection from Chris, and finally your installation from Tyler and Caleb. EVERYTHING went smoothly and my radon reading went from 3.14 to 0.32 overnight! So peace of mind is well worth the very competitive price and the easy process.

Every encounter with the employees of this company has been great. We recently purchased a home that had very high levels of radon, when I called them to get a quote Mary Anne was extremely helpful and informative. We have a gravel crawl space and she explained the whole process including the type of material they used as well as the sealing products. Then when they came out to give the estimate it was very quick and Chris was very informative as well. The day of installation they arrived at 7 am on the dot and were actually quicker than they originally told me. Once they were done the guys that installed the mitigation system they showed me everything they did, how to read the monitor and what issues would sound/look like. There was open communication the entire time and overall I was very happy with their services. I would recommend them to anyone in the area!

Higher than average radon levels in your home is never good. With all the radon mitigation companies out there, it can be very challenging knowing who to choose. I don't normally write reviews, but I'm hoping this review helps you with your decision about choosing the best company for radon mitigation. I had a few estimates for radon mitigation and was very pleased that I hired Guardian for the job. Pricing is fair and the team is helpful and friendly. It was a very positive experience from start to finish.
I first spoke with Mary Ann who quickly responded to my email inquiry about an estimate and scheduled one right away for me. She proactively and thoroughly explained who would be coming out to the home, what to expect, and was always prompt with replies to my questions. Mike was
the gentleman who came out to estimate the project quoting a very fair price, provided good information and options, and answered all my questions and concerns. The team of Mike and Matt came out to install the radon mitigation system today and were on-time, efficient (3-hour install), personable, polite, and conscientious about clean-up. Mike even helped troubleshoot and fix one of my garage lights after the install- BONUS! I'm so glad to have found Guardian , and I would recommend them to anyone.
Thank you so much Mary Ann, Mike, and Matt for your great service!!

Great craftsmanship and attention to detail. More importantly though, the radon levels have drastically dropped in our home. Before, the level in our home was greater than 8 pCi/L (double the recommended limit). Since the system was installed, we reran the test and now have a very safe level of 0.7 pCi/L (only slightly higher than outdoor radon levels). Amazing work!

Superb company and experience! They are on time, professional, knowledgeable, friendly and clean! And their price is fair. They got us in on their schedule quickly. That’s why they have the perfect review rating! Highly recommend.
