Beware of the extra charges from this company. I purchased a new home and per the inspection, one of the items that the sellers agreed to take care of was to have a radon system installed. Radon Safety LLC quoted the sellers $1398.00 for the installation. I received the check at closing for the work to be completed. When the radon company tech came out, he said it would be an additional $300.00 because he had to hire another company to core a hole in my foundation. He then had to make a call to coordinate with the other company to set up another appt when they were both available. I had to take another day off of work, but they both showed up and the job was completed in about 2 hrs. At the very least, they should have requested what type of foundation the home had before quoting the work. I called the office to tell them they should honor the quote, and I was told by Amanda that the extra cost was "unavoidable". It was ABSOLUTELY AVOIDABLE had they quoted the job accurately! Not happy that I had to pay the added charge out of my pocket when I could have received the entire amount from the sellers. Beware of the extra charges from this company. read more

I received a quote from Radon Safety back in January. At the time, I was not quite ready to book the service, but Holly let me know they would honor the rate quoted when I was ready. Fast forward to September, I called and Holly scheduled me an install for two weeks later. The installer, Alejandro showed up right when I expected him between 8 and 9 AM. He could not have been kinder and asked me where I would like the system set up and let me know it was going to take about four hours to complete the job. Post install, we were left with a radon tester and were told to give them a call if we experienced any issues (such as the system making a loud noise). I followed up with Holly later in the day and settled up my balance and she emailed me the warranty. From start to finish this company delivered... Amazing customer service, professionalism, and a fair price. I could not be more pleased read more

Needing to install a new radon mitigation system in our home, we reached out to three companies for their quotes. Radon Safety was the first to respond and the company with the lowest quote. Holly was my main point of contact. She is fast in her replies, clear spoken in her explanation of the quote, work required and timeline, and generally cheerful on the phone. Within 20 minutes of the work completion, she called me with the final cost (exactly what I was quoted, truly no strings attached) and had the receipt emailed to me only moments later. Alejandro actually did the installation of the radon mitigation system. He was 15 minutes early, very polite and engaging, and worked with me to find the best spot possible to ensure low-visibility outside of the home with the least amount of eye-sore in our finished basement. I think I picked the most complicated spot to install the pipe, but Alejandro said it was no problem and that he would make it work. And he did so very quickly. The work was completed in about 3 hours (we were quoted 3-5). Despite my home being completely empty as we haven't moved in yet, he took off his shoes outside the door every time he had to enter the house. I really appreciated the gesture to help keep our home clean. He really was awesome, so thank you for sending him! I am 100% satisfied with their work and highly highly highly recommend them to anyone looking to install or repair a radon mitigation system. read more

I don't like to post negative reviews, but in this case, I thought Radon Safety deserved one. I doubt if all the positive reviews posted on Yelp are legit. After receiving a quote based on my responses online, I sent an email asking for a further explanation of their quote and how it was that they could quote me a price without actually coming out to further clarify my situation. A reply answering my concerns might have been satisfactory, but there was no response, no wanting to set an installation date, nothing, nada. I can only ascertain that a company that can't even take the time to try to get my business, outside of sending a boilerplate iniitial response, would not be very responsive if I needed the follow-up services that it touts and bad-mouths other companies about. read more

Absolutely terrible customer service! I reached out on 3/31/2022 for information and got an email explaining why their prices were so high. I responded with a few questions to "Holly" on the same day and never hear back. On 4/28/2022, I called again and "Holly" claimed she had no emails from that day, then hung up! When I tried calling back, my call was routed to voice mail. Not only is the company's customer service rude and incompetent, their prices are much higher than any of the other radon mitigation services. Needless to say, I DO NOT recommend this company and would never do business with them. By the way, they expect the customer to do all the work on determining square footage, partitions, etc in crawl spaces and they quote based on that. They DO NOT come out and provide estimates themselves. read more

Radon Safety was great to do business with! Professional, honest, and reliable! Starting with Holly who was kind and fantastic getting my appointment set, and all communications! The installer (whose name has slipped my mind) was also very professional and kind. He showed up on time(rare in Colorado in my experience)and had completed the install of the radon equipment in only 2 hours! Radon Safety was also the best quote my Realtor had received of the three quotes she got from other radon companies! Thank you Radon Safety! read more

For the second time in two years (last house and this current house) I have used Radon Safety LLC to put in a mitigation system. And they have been consistent with doing an AWESOME job. They were on time, professional, efficient and courteous. And of course, they brought my radon levels way down! I was over 5 and now it is less than 2! Radon Safety LLC 303-462-5000 radonsafety@gmail.com 8 Years BBB Gold Star Winner read more

The initial test came back at 7.7. I chose Radon Safety because, being a consultant myself, I could tell from their marketing that they really cared about doing things correctly. And when I asked for other quotes they all came back at the same numbers. Their initial quote ended up being off by a couple hundred dollars because of an unforeseen construction issue that required concrete drilling rather than wood drilling. But that's fine. Afterward, the test came back at 0.3. Which is basically the margin of error in these tests. Less than a week between calling them and the installation being finished. read more

So I had Radon Safety come out to my house to modify a cluster install from when we bought our house. Was still getting high readings and felt duped by the previous installer. Holly & Alejandro actually listened to my problem & were super helpful in coming up with a very nice minimally invasive solution to an already finished basement. Very professional & very nice (not easy to find nowadays) & I'd recommend them to anyone with a radon issue. read more

We had Radon Safety LLC install our mitigation system shortly after building our new home in 2014. Every aspect of their service was A+. Holly is super helpful and the technician did a very nice and clean install. The system worked well and we were very pleased all around. We were so pleased, here we are about 5 years later, and they will be installing a new system at our new home. I would highly recommend Radon Safety to anyone in need of this type of service. In a day of big promises and small returns, it's nice to deal with a company who goes out of their way to do things the right way. read more

Top notch! I contacted a number of Radon Mitigation companies to decide who I would hire to do the needed work at my home. Radon Safety's proposal was by far the best. Not only cost, but information with inclusions/exclusions. It left no questions except when they could do the installation. The installer (Alex Goble) came at the specified time and was efficient at his trade. What was superb was the information he provided. I have never lived in an area that had basements and the need for radon gas mitigation, so I asked a ton of questions. Alex was thorough and clear on his answers and how everything worked. Couldn't ask for a nicer installer and I have full confidence in the system and installation. read more

I am a real estate broker in the area and I refer all my clients in need of a radon mitigation system to Radon Safety. I used to use a different company, but when the buyers of my own home I was selling requested Radon Safety, I figured "why not?" Tiffany in the office was very helpful and quick to respond for my own home, and now I'm a convert and use them for everything. Scheduling installs has never been an issue and the pricing has been among the best I've found. They also cover all areas of the Metro area. My own home was in Brighton, I've had them do installs in SE Aurora, Westminster and a few different areas of Denver. There might even be some more I can't remember! read more

Rarely do I ever write reviews, but these guys were so great I couldn't help but get on and hopefully help you homeowners out there who need mitigation done. These guys were top-notch, home-run hitters. Sure, if you compare quotes from around the metro area theirs may be a tad more, but seriously, it's because they do it right the first time and they don't cut corners, like I've heard of a couple other companies in the area do. They were quick to get us a quote, Alex (our installer) was incredible from the moment he knocked on our door to the last handshake, following the completion of the project. He was courteous, professional, and worked his butt off to get the job done right. Listen, their work involves the wellbeing and safety of your family ... don't skimp or be cheap and go with the other (maybe less expensive) guys. I sleep real well at night knowing that my system, my family is safe because I know our system is doing it's job right, especially following our test results (from a third-party company) after Alex completed the mitigation install. Have I said enough to convince you all to choose Alex and Radon Safety? Do it, it's worth it. read more

I was very cautious. The weird marketing and putting down other installers was a big red flag to me, but it seems ever one in this business does the same. So I took the leap. The installers are all contractors and that also had me a bit Leary, but it seems they screen them well. Brian spent about a 1/2 hour with me walking around the house, and looking for the best place to install it. I really didn't want it near a window. We went around a few options, then thought about it some more. We didn't want to run it through the garage because the run was too long. But then he realized he could get it out fairly easily if he just put it straight out. I had been thinking on where I wanted it for literally years and hadn't thought of that option. He was done in 3 hours, clean, nice install. 4" PCV. Very happy with it, can't hear the fan or the exit sound inside the house as it's on the side of the garage. Price was competitive, Perfect! Thank you Brian! My only regret is that I hadn't seen this option for the install, because if I had, I would have done it myself. Well, at least after 7 years of procrastinating, it's done! read more

Several weeks ago I wrote a review stating that there had been some miscommunication, but I thought Radon Safety was probably a good company. After a call from the owner clearing things up, I had them do the radon mitigation work. The job turned out great and subsequent tests showed the radon levels at 1.9 and 1.6 respectively, well below the EPA guidance of 4.0. Another huge point for this company was their "no strings" warranty. Another company I was talking to required a radon test every two years by a certified radon tester to keep the lifetime warranty in effect. That would cost about $125 every two years and the results had to be sent to the contractor. Radon Safety had a straightforward lifetime guarantee with no gotcha conditions. The workmanship was first rate and it was clear he knew what he was doing. read more

Wonderful. They go above and beyond to get the job done. Sarah in the office is great at scheduling and is always friendly. Alejandro called when he was on his way to our house. I really liked that. He also went out of his way to make sure the job was done right and explained what was being done. I can't hear the fan. Amazing! read more

I have had at least 4 systems installed in different houses over the years, and I have to say, without hesitation, that Radon Safety was by far, the best experience I have ever had! 1. Friendly helpful staff (even talked to the owner), 2. Simple and easy to understand estimate 3. Prompt and accommodating scheduling 4. Polite, courteous and professional installer 5. Friendly follow-up inquiry about the experience. Couldn't be happier. Great company! read more

Radon Safety LLC is great . They installed her unit today and everything went so smoothly even from day one when we first contacted them so we would highly recommend them and their prices are the best around and they give five-star customer service !! read more

We shopped around for a radon mitigation expert and found Radon Safety. The quote was competitive and timely. While the house had not been seen by them before the quote, we were assured that they had done many homes in the area and the quote was solid. Once we gave them the go-ahead, we were scheduled for the next week and the technician Mike was a few minutes early. Mike asked us if we had ideas about where to install this, and he really listened to our concerns and ideas. Mike answered our questions, and offered his expertise on how to not only get the best results, but how to install it in the most aesthetic manner. He took the time to explain how the radon builds up under the foundation, how it is pumped out, and how it does not build up again after the radon pump is functioning. Mike did the work quickly and cleanly, left no mess, and made a change when we realized that the pipe may interfere with a garage door. Nice guy and very professional. If you are concerned about the one bad review, please know that the owner's reply to Elly's review may have came across as a bit defensive, but I realize it is more that he is passionate about his work and his business. I am glad that we were swayed by the other five star reviewers and not the one reviewer who didn't give them a fair chance. read more

I had to have a radon mitigation system installed in my house so I found Radon Safety LLC. EXCELLENT WORK! Alex came in, he was super professional, efficient, explained everything and was done quickly. He even got along with the dog and when he had to turn off power, he asked to make sure my WiFi was not affected. HIGHLY RECOMMEND read more

I am a local realtor who refers Radon Safety to my buyers and sellers. They are fast, courteous, have reasonable prices, and Holly is just amazing! She takes the brunt of all of my questions and has become a true expert resource for me and all things radon. I have never had an issue with their services, especially when I have a client who is very particular how and where the system is installed, the installers gladly oblige clients to the best of their ability. read more

After comparing prices between companies and what was included with Radon Safety we knew it made the most sense to choose them. The staff was professional and walked me through exactly what would happen. The work was clean and I'm happy to say the radon levels in our house went from 6.0 pCi/l to 0.3 pCi/l. read more

If ever there is a need for reputable, honest companies, the time is now; Radon Safety is one of those companies. So professional and competent - they stand behind their workmanship and do what they promise. I highly recommend this company - affordable, quality work and very professional from start to finish. read more

We recently purchased a home in west Arvada. During the inspection we learned our radon levels were way too high. We made arrangements with the sellers to deal with the actual work providing they paid for it. Our realtor recommended we use Radon Safety. We found Holly to be very efficient, friendly and easy to work with and Allejandro was a fantastic technician who did an amazing job installing our radon mitigation system. Our radon went from 7.6 (over 4 is too high) to a 1.3. The company also offered painting of the exterior system at a nominal fee. We were extremely pleased with our dealings with Radon Safety and highly recommend them! read more

I did my research and price comparison to other companies and Radon Safety was not only one of the better priced option but they didn't try to up-sell me on anything. One flat fee is rare and was a breath of fresh air. They were great to work with from start to finish. I changed my install date and they gladly accommodated my schedule. The installer (Alex) showed up on time, walked through the house with me and went over the install options. He even jumped into my attic to assess a possible location. He was friendly and easy to work with. Overall, was a great experience and pain-free. I would absolutely recommend!!! read more

Radon Safety installed a radon mitigation system in our home and it was a smooth process. Their prices are very competitive with other companies. Holly, who is the one you talk to if you call, is friendly and helpful. Tim, the installer, was fabulous. He was friendly, extremely knowledgeable, very neat, and he loved our pets. (That's always a big plus for me!) Once he arrived he discovered he would have to drill through concrete, which was not in the original estimate. They were very good about working with us on the added cost for that even though it wasn't their fault. I would highly recommend Radon Safety if you need to have a mitigation system installed! read more

I am a Realtor, and often times we find ourselves in a situation that we need someone dependable to install radon mitigation system. Day before yesterday, I called, needed it NOW... got in-touch with Radon Safety, the pricing was right and had a quote within 5 minutes sent to my email. My clients called and they were out the next and had it installed. I am impressed with Radon Safety professional team and work ethics. They are #1 on my list. read more

Wow! Really, just wow! The installers arrived on-time, completed the work in less time than initially expected and the work was clean. Once it was installed, they walked me through the process, they were not afraid nor did they seem to mind that I was watching them work. In fact, once it was done, they showed me what was done, how to turn on and off the system (if ever needed), and asked me if I had any questions. Both installers were very professional and courteous. No debris was left behind, nothing for me to clean up (including dust) and they even made sure to re-seal the vapor barrier in the basement with white tape so that it was unnoticeable that they had to break it to access the electrical. Even further, the noticed a problem with the sump pump and the dirt that had collected in it (we just bought the house from out of state and I've never lived in a house with a sump pump or even a basement). Instead of just telling me about the problem, they actually cleared out the sump pump area (removed the dirt) to ensure the system would work as expected. Amazing job!! Thank you! read more

So dissapointed with this company, I hired them with weeks in advance to complete a job they cancelled 1/2 hour before the work was supposed to be completed. They don't have enough help to have somone else step in and complete the work. They're very irresponsible I don't recommend them, they were anxious to get me off the phone and take my business elsewhere. This job involved a real estate transaction so needles to say they put many people in a real predicament. read more

Did not deliver! Through our realtors at Coldwell Banker, we got 3 estimates for radon mitigation at our 4000 sf ranch home that had a small 400 sf finished basement. Mike at Radon Safety gave us a $995 quote for radon mitigation, saying they only needed to do the finished room to mitigate. We got 2 additional estimates for approximately $3000 to mitigate the entire crawl space and finished basement. We decided to try Radon Safety. When Radon Safety came to do the work, they said they had underestimated the scope, it would now be $2000 and that they had to do the entire crawl space and finished basement room. They set up another time a few days later to do the project. When they came to do it, they said 'we had estimated the square footage in the crawl space to be 1800, now we see that it is 3800. They gave us a verbal quote of $4000 to complete it. When we said we were not willing to pay that, they pulled off the job. Mike told me, as well our realtor that they could not do it for the 2nd estimated price, leaving us scrambling to schedule another contractor 3 days before closing the sale of our house. Nobody was available at such short notice, we had to make other arrangements with the buyers at closing. Our realtors were the intermediary in this contract with Radon Safety and can provide documentation if needed. read more

Love these guys. They gave me a great price and did great work. There are a lot of scams with radon companies and this isn't one of them. Highly recommend! read more

Excellent! John was professional. Described everything we needed to know about the installation. Helped us find the best place to build the system so that it did not interfere with any pipes or ventilation ducts. And was extremely concerned with performing a job worthy of his skills in that he wanted everything to be aesthetically pleasing as well as effective. I wish more people had as much pride in their work. Thank you John. Would definitely highly recommend. read more

Recommended. We hired Radon Safety after comparing prices and reviews of radon companies. They installed a mitigation system which reduced the radon level, but not enough to be safe. They returned to install a larger fan, which reduced the radon level again, but still not enough. They returned to install a second "core" (hole in the foundation to pump contaminated air out), which reduced the radon to a safe level. Throughout the process, they returned phone calls and emails promptly and listened to understand my concerns. There was one communication gap that resulted in the installer not showing up one day, but otherwise they did well, seeing the project through until the radon level was safe. read more

Radon Safety did an excellent job! They are fast, professional and willing to do whatever it takes to correct a problem!

I live in a new construction neighborhood and we had 10 homes on our street that was looking into a radon mitigation system. We just had our install yesterday. Tim was awesome! He called before he showed up and came at the beginning of the time window, was open to any questions, patient and was very professional. I contacted 6 different companies, each referred to me and compared apples to apples. It was a month or so of research! You get what you pay for. Ultimately, I went with my gut and paid slightly more because of their track record, longevity in the business, customer service of Holly who answered questions from me over 3 weeks. After seeing several installs of mitigation systems on various homes in our neighborhood, I genuinely believe that they would do a great job. I am so glad I went with my gut and picked Radon Safety. The work was aesthetically pleasing (something I care about) nice and neat including the PVC, caulking, etc. I am confident that they will take care of any issues should any should come up. One of my best experiences in hiring trade services. Tim and Holly-Thanks so much, I will refer Radon Safety to anyone in my network. read more
