They did a great job - quick, respectful, professional, and reasonable! Highly recommend. We had a new radon mitigation system installed on an existing home.
Radon Safety and their staff are excellent!
Really satisfied with service they provided. Price, communication, professionalism of installers - 5 stars. I couldn't believe they installed membrane in my less than 2 feet high crawl space in one day. They provided test kit for checking radon level after job done. I ordered another one from the company I did…
Fast, efficient, flexible, and friendly. Thanks for installing the radon system so that the new family buying my dad's home will be safe.
10/10 recommend! We needed to get a raddon mitigation system installed and when we reached out to shop quotes, they were easy to work with and the turn around time was wonderful. At the time of service, it was quick, and he was very informative. They made the process very easy and stress free! Thank you!
Very professional. Got the job done quickly and without any extraneous issues.
The company and Amanda were great and very professional. The installer, Nick was the best, easy to talk to, described process, very efficient and the completed work was wonderful. Easy to give 5 plus stars
Robert Lang was great - our home is older and he was able to install the mitigation system into a trickier situation in less than a day. He also discounted our total because of the challenges. Would highly recommend!
I've worked with Radon Safety on perhaps 5-10 projects over the last approx 10 years. The most recent project was my home. For many years my business brought me into contact with 50+ service companies. While I did come across a few home service and contractor businesses that demonstrated legitimate care and concern,…
Working with Radon Safety was amazing! They did a great job, listened to our requests for placement and worked with us to troubleshoot any potential issues with our OLD house. They took the time to understand our wants and needs where other radon companies did not.
Absolutely amazing experience. There is not a single thing I can think to complain about. The price was excellent compared to the others I got quoted by, the communication was great, the mitigation professionals were kind, knowledgeable and very skilled and the results were far beyond my expectations. Honestly…
Do yourself a favor and hire them! Great service...Amanda is amazing. Very knowledgeable...Alejandro is the best! They are trustworthy and get the job done.
I don't know why anyone would use anyone else. This was an installation on a 28 year old house with many basement areas finished. The installer identified an installation (not using the sump) that had no impact on finished areas and was totally effective. Radon rates were reduced by almost 90%. They offer a…
The tech was on time and very efficient. Had the job done in three hours. Good price and great service.
Radon Saftey did an amazing job with my radon mitigation install. Their installer, Alejandro, took his time to discuss with me the plan and made sure I was happy with were ducting was going to be placed. They were careful, detailed, and the final installation looks professional with no corners cut. The cost was…
Great company!! Fast installation, very knowledgeable and thorough!!
They showed up early in the 2-hour window. They completed it in about 4-5 hours. I am happy with their work. Highly recommend Radon Safety LLC.
I had a great experience with this company! It was so easy and smooth to get a quote, plan a date, and have one of their technicians get out to my place. Very clean, and unobtrusive installation at a great price. Highly recommended
Nick the installer showed up on time, was very professional and installed the system very quickly. The site was kept clean and when he finished, he explained what I need to know to ensure the system is operating efficiently. I would highly recommend using Radon Safety to anyone in need of a radon mitigation system. Well done!
Great working with them! The tech was knowledgeable and helpful throughout the process.
Great people did an excellent job for me. On time, friendly, finished early and cleaned up really nice. Best of all my radon reading went from 10 (4 being unsafe) to 1 in one week.
outstanding company, very professional and cooperative. Easy to work with, quality work
We have purchased systems for three different houses. They are responsive, helpful, and reliable. I’ll use this company forever! They even came through when we had a short turnaround after an inspection.
Professional job, Nick did a great job and answered all my questions. The extended 11 year warranty on the blower / exhaust fan was a great selling point.
Amanda was fantastic, she made the whole process very easy and helped with all of my questions. Nickolas is a true expert in the installation of Radon systems and did an excellent installation. I can highly recommend Radon Safety LLC to anyone wanting a Radon system.
Had a unit installed last year in Aug, took a while for us to get to a good level (May) timing on both ends didn't help, but overall responsive and took the time to come out a few times at no additional cost
Great company, service and price. Highly recommend!
Nextdoor reviews were good so I called Radon Safety. Holly was very helpful and provided a quote after I answered a few emailed questions. Nick came out a few days later, discussed the process, and a few hours later, was done with the install. Professional job and it looks good. Glad to get this done.
Radon Safety is the best! They did a super job, my radon level started dropping immediately after they installed a fan on my "passive" radon system. And with the best warranty in the business, I'm very happy I chose Radon Safety!
The installer was friendly and explained everything throughly. The office staff was super helpful.
Very easy to work with, quality material, and great installation. The installer was very polite and explained everything very clearly. Would definitely use again if I have any other issues with Radon.
Had a great experience! The installer was patient and courteous as we discussed all options for install location. He offered input without being pushy, and helped us make the best decision. Install did not take long, looks professional, and did a good job cleaning up after. Would. definitely use again, and recommend.
Everything was up front and discounts were honored. Service was quick, professional, and on-time. Our radon results immediately dropped to safe levels. I would absolutely work with them again or recommend Radon Safety LLC to friends and family.
Radon Safety and Nick were super professional, efficient, and very flexible with my schedule and my HOA requirements. Nick had to make some changes to the original plan once he arrived on site, but I would have never known. He was very competent and professional and explained everything to me. I would recommend them…
The installer was early and did a good job. He painted the outside to match the house for an extra $99. The whole job turned out great.
I used Radon Safety for two of my houses and I cannot be happier. The radon levels went way lower in both houses than it was and now at 3 pCi/L and lower on a commercial indicator. The installer Alejandro found a leak in my kitchen drain as well that got it fixed in time with minimal cost. That leak would have…
Nick from Radon Safety was fantastic. We walked through the house and talked through several places the Radon Mitigaion System could go, the best spot and we landed on the Laundry Room. He walked me through how their system works, then was prompt, clean, and mindful of me working from home while he performed the…
Excellent!!
The radon mitigation system works great! I would definitely recommend This business.
Holly was very quick and responsive when getting a quote and setting up the installation. Ryan the installer was on time, did a very clean professional install and explained everything very well. This was one of the easiest contractors I have work with. Pricing was very competitive for radon mitigation systems.
