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.
Holly was wonderful to work with, always responsive to our concerns and questions. Easy to schedule and on time. Alejandro (Radon installer) was awesome. Very responsive to our questions, willing to work with us as far as where we wanted the radon installed. Great, Great over all. Definitely recommend them! Thank you!
Did an excellent job of routing the exhaust pipe through the attic to outside.
From getting a quote to scheduling an install to project completion and payment/issuance of warranty! It couldn’t have been easier! Absolutely no games. I’m lucky to have found them and I will be recommending to anyone.
Radon Safety LLC provided excellent service for a very competitive price. The work included installation of a radon mitigation system in our basement with an exterior vent to above the roof line. The work was done exactly as promised. I’m very satisfied and can enthusiastically recommend this company.
Great experience with Radon Safety LLC, they were quick with response and got my mitigation system installed in 2 hours. Quality and professionalism was top notch. Don't settle for another company just because it's cheaper! These guys know their stuff! Thanks Randon Safety!
Have a great price and then the services was even better. You will get a no hassle price followed by a great system install and customer service experience. The best!
Company office has excellent scheduling/communication processes in place and we had a very high quality install by friendly service tech. I love that they guarentee re-test will pass or additional work will be done free of charge until tests pass.
Holly was great and extremely helpful getting me set up and Mark the tech did a perfect job installing the system.
Radon Safety LLC installed a radon mitigation system in my home today, and the workmanship was excellent. From the start, the whole process of getting a mitigation system installed was very professional. I contacted their company through their website, and they sent me a reply within 24 hours. In the reply they…
Radon mitigation? Best company ever!! No nonsense business that did everything they said they would at the price they quoted. No surprising extra fees or charges. If you need radon mitigation call Radon Safety and get a quote. Their installer Mark arrived on time and completed the work under the expected time. He…
The process was clear and everyone was helpful. We needed to get additional appoval from HOA and Holly really worked with us. Nick was awesome at install. He didn't rush and took the time to help figure out the best place to put things.
Last week I had a Radon Mitigation done on my basement. From Jason's on time arrival to his finishing at his estimated time the installation was thorough with the unit installed being quiet and unobtrusive. Holly in the office followed through with all scheduling and final paperwork arriving in a timely manner. I…
Ryan performed wonderful work on this radon mitigation project! He was such a hard worker, overcoming some challenges of our site without complaint. The final product was reasonably priced and beautifully installed! He takes great pride in his work, obviously!! We appreciate Ryan and the entire team!
Great service. Competitive pricing. Professional and responsive.
Great experience overall and the installation with Jesse was very smooth and quality of work was excellent!
They were wonderful! Very friendly, skilled and responsive. I highly recommend this company.
These guys rock so hard I don't know how else to say it. A+++ Went out of their way to think outside the box to install an exterior radon system without making it look like an eyesore. The best.
We needed a radon fan installed before we sold our house. Jordan came over right on time, had the exact fan that we needed, took care of it very quickly and very efficiently! Great employee! I'd use them anytime!
I completed an online form to get an estimate for radon mitigation from Radon Safety LLC and I received an estimate within 12 hours! Once a decision was made to move forward with getting the work done, Holly was able to get us scheduled again in less than 12 hours. We had Nick come out and install a week later. He…
I had a great experience with Radon Safety, LLC. Easy quoting process, easy scheduling, very fair prices, & great work. Highly reccomend!
I used Radon Safety for the installation of my home radon system. I was actually blown away by the professionalism of their team. The fit and finish of the final product is top notch. I couldn't have had a better experience.
Holly and Jesse were fantastic to work with. Holly provided very detailed scope of work, always responded super promptly, was very patient with my HOA delay issues. Jesse showed up on time both days, also provided very detailed information on the work to be done, was helpful with answering questions to the HOA. Great experience! Thanks!!
Super quick and easy install, maybe two hours start to finish and placed in a very discreet manner through basement/garage/roof. You’d never know it was there!
Holly and Jason were both great to work with. Holly ensured all my questions were answered and provided my quote in a very timely manner. Jason did a great job with the installation. I would recommend Radon Safety to anyone needing a radon system installed.
Service performed was installation of a radon mitigation system. Radon Safety responded promptly to my request for a proposal and estimate and completed the work fast. The installer was able to put the whole exterior pipe and fan inside an attached tool storage closet and there is only a short piece of PVC pipe…
The Radon Safety LLC team knocked out a radon mitigation system in less than 2 hours - top notch install, couldn't be happier with the service today - thanks gents!
Great company. Our level was rather high to start with. Radon Safety LLC continued to work with us until the level was below 4. We never had to get ahold of them about the test results…..Holly always emailed us with the results and, in our case, to set up another appointment(s) to continue to get the levels down.…
Just overall easy to work with. They were on time and very professional. They had given us a quote over the phone and while we were okay with the price they had given, we ended up saving on install since we already had a passive Radon system and they just had to add the fan to make it active. We didn’t know that…
Totally happy with the installation. The Technician was able devise a way to get around a number of obstacles and still provide an aesthetically pleasing solution. Process from quote to installation was quick and painless. Good experience, good value, would definitely recommend you check them out.
This is a great company to work with! Very professional! If you need a radon system look no further. Best quality and value all at one place.
The customer service was top-notch! My emails were always promptly answered with detailed responses. The technician called when he said he was going to call, the work was completed in a very timely manner and there was no mess for me to clean up!
Contacted Radon Safety to have our system checked and updated. Holly was super helpful and very responsive throughout the whole process. And, Alejandro did a great job with the install. Would definitely recommend!

Mark did a fantastic job on the installation. It was both quick and professional and in addition he left everything as clean or cleaner than it was. He was completely non disruptive to the family and very few if any body would even notice any changes either inside or out to our home. Would highly recommend.
