I could not be more pleased with the finished product and their customer service from the first inquiry to installation. From start to finish, the team was responsive (within hours, and often within minutes) to all of our questions. Their work is very well done - I was involved in the decision-making for placement of the system, and for a radon mitigation system, it's as subtly placed as it could be. I wish I could remember the name of the gentleman who did the work here - he was friendly, collaborative/communicative about everything he was doing, and gave me updates on how it was going. SO PLEASED!

We had a great experience! Zach was prompt and was able to come early in the morning to work around our schedules. He also was quick and efficient and cleaned up the work space when he was finished, we highly recommend these guys! Amazing service!

5280 Radon Mitigation is a phenomenal company to work with and rely on to get the job done! They have saved several of my real estate transactions from falling apart due to their high quality work, customer service, and ability to get the installation done quickly. They are my go-to radon mitigation company! Thanks for providing such fantastic service!

Our amazing realtor recommended these guys for our radon mitigation. Couldn't be happier. They were so friendly (albeit, they showed up a bit late). They stayed to get the job done. Our camper was in the way of where we wanted the mitigation to come out, but the tech made it work so we didn't need to reschedule. 5280 was WAY less expensive than other companies, and they weren't trying to rip us off with unnecessary mufflers, or anything else. I highly recommend these guys. You won't be disappointed!

Bryan was very helpful and explained in detail our radon mitigation options. He charged us a very fair price and completed the job quickly, despite some setbacks. I would definitely use them again!

It has been about six months since we received our radon mitigation system. Everything is running smoothly. I was very specific in saying how I wanted the pipes to be run up through the attic and out the roof. They followed my wishes spot on! It was not an easy job for them, but they never complained or tried to change my mind. They just made it happen. We had initially hired another company, they had come out and drilled holes in our slab, ran into some difficulties, left at lunch and we never saw or heard from them again. 5280 was the exact opposite kind of experience. They faced the difficulties and came up with great solutions. Only thing I would suggest is that they use a little better adhesive for attaching the plastic in the crawlspace to the foundation. I have never asked 5280 to come back out to patch the few little areas but I am sure if I did that they would be here in a heartbeat. They are that kind of company.

5280 Radon has done multiple installations in our neighborhood -- Heritage Todd Creek in Thornton. Had only heard good things about them so gave them a call. Three days later I've now got their mitigation system in my basement.

The whole process was super easy. Installer was very professional. Phoned in advance. Arrived as scheduled. Very pleasant and efficient fellow. Appears to have done a good job. Painted the exterior vent to match the rest of the house-- I supplied the paint. Cleaned up everything. Explained everything.

They installed a nifty little air pressure gauge that lets me tell the system is working.

Price was very competitive.

I recommend them.

Brian from 5280 Radon came to our home today to diagnose a problem that our builder could not seem to fix. He was able to locate and resolve the issue in 5 minutes, and our system is once again silent. Brian was on time, professional, well mannered, and was very knowledgable. He explained what had happened, how he fixed it. I would very highly recommend 5280 Radon to anyone who needs service for their Radon system. It's great to see business owners who genuinely care about their customers like Brian does. Keep up the great work!

They were fast, clean, friendly and easy to work with. Chris got back to me within at least 1 day for all email correspondence and Sandy did an excellent job on installation. He was professional, cleaned up after the job and even accepted the even more difficult task of wedging the fan between two close buildings. I didn't look at other companies to compare prices but I was told by friends that the price was super reasonable.

Chris took his time explaining everything to me overt the phone. Did not try to up sale me. In fact advised me honestly that doing some things were not necessary. He patiently accepted me cancelling an appointment (with plenty of notice of course), and honored the quote he originally gave to me when I rescheduled. They serviced my area way out on the I70 Corridor without any extra charge. They upgraded part of my system upon my request for no additional charge. The technician was a true pro. He worked fast but accurately and with high quality workmanship. I expressed my desires to him for the system to go through the attic. Even though it would have been way easier to go outside and up. He made the attic happen for me even though I know it took him 2 to 3 hours longer to do it. Then he answered all my questions to a T! I wish more companies were this good. Oh by the way, the Radon Mitigation not only works awesome but my windows no longer have dripping condensation building every morning in the winter. Very fairly priced for the degree of professionalism you get with these guys. Go with no-one else!

I am 71 years old and have owned a home since I was 26. In that time, I have employed general contractors, electricians, HVAC, plumbers, carpenters, sheet-rockers, carpet layers, roofers, gutter guys, and landscapers. Some were good and some very bad.

This is my first experience with radon mitigation. My radon level in my basement was 11.

Prior to engaging 5280 Mitigation, I did extensive reaserch on radon, and on companies doing mitigation.

Chris and Bryan own 5280. Chris is easy to talk to, very helpful, and very knowledgeable. He also returns calls promptly.

When I contracted with Chris, he setup the installation in a timely manner. The contract calls for reducing the radon level to 4.0 or lower. The installer, Sandy, arrived on time and was very professional and took extra time and effort to dig out the pit to make it large enough to provide sufficient suction.

A week after installation, I retested the radon level. It came back at 7.5 which is above the 4.0 standard.

I have had some awful experiences with trying to get contractors to come back and correct work. I was expecting the worse when I called and left a message for Chris. To my delight, he called right back and setup up an appointment to correct it. Bryan came out and installed a larger fan (in a snow storm).

This time, the reading came back at 4.6...still too high. I was wondering if Chris might say something like "well that's close enough". Nope, Chris said he will send Bryan back to figure a way to drop it to 4 or under.

It is a pleasure to work with a company who does what they say and returns calls. I will do an update on this review when I get the next test back. I highly recommend this company if you need radon mitigation.

Update as of July10, 2017.

Bryan came out as scheduled.

He drilled a secondary pit and attached it to the main pit via 4" piping. I retested about a week later. The result came back at 1.1

Great!!

This is a highly reliable and effective company..

We had high radon levels in our 1920s bungalow and wanted to get it fixed as soon as we realized it. I appreciated the ease of scheduling and getting our radon mitigation system completed. Everyone I talked to was so kind and helpful. And they were not trying to up-sell me at all. I appreciated their honesty in what my home really needed.

5280 Radon was great to work with! Everyone I worked with was very helpful answering all of my questions and helping me through this process. The technicians were efficient in their testing and they got our system installed very quickly after finding high levels of radon in our basement. I would definitely recommend them to all my family and friends. Thank you for your help, 5280 Radon!

Our realtor had suggested other Radon companies but they lacked the "first call warmth". Chris emailed an estimate within 10 minutes, once again our agent tried pushing bigger companies at closing...We didn't listen to the buzz and neither should you. Have Brian take care of this. He was awesome what a gift of customer service and pride of business ownership!!. He had us smiling throughout the entire process, as 1st time home owners with a vintage house this is very appreciated.

Very very fair price and guaranteed work done by locally proud business owners. Too bad this is one of those things that is a one time thing, Id look forward to a quarterly visit from Brian if not, sooo friendly!. Don't hesitate book it!!!

Courteous, fast service. Was given a quote over the phone (very reasonable). The guys came out the very next week and we were all set with a simple installation. They even let me dictate where the piping went on the side of our house (they were super patient with me). They even identified that my sum pump was broken and so we got that fixed too. Quality all around. I will report back with the degree to which our radon was mitigated though since they have a warranty that it will be below 3.0 we will be good to go one way or another.

I needed help making sure installing a new sump pump didn't jeopardize the effectiveness of my radon mitigation unit. I was very lucky to find 5280 Radon Mitigation. Although 5280 didn't originally install the unit, 5280 treated me as if they did. Chris took time to answer all of my questions and Bryan did a great job putting the pit back together after the pump was put in. I will definitely call these guys in the future if I have any further needs.

5280 Radon is a great company to work with. Chris explained the process and paperwork. Bryan came out and surveyed our basement. He listened to our thoughts and wishes, and made it work. The radon levels did not drop as expected, and he came out two additional times to make improvements to get the radon down to 2.1 pCi/L. He was also able to mitigate the fan noise with a muffler. We are very happy with our radon mitigation system.

I found out I had a real radon problem after doing 2 home tests, so I called these guys to install a radon mitigation system. They were able to work with my schedule and arrived on time with more guys than they really needed to get the job done. After reviewing the inadequate system the builder put in my home, they gave me a few options on best location for the proper system to provide maximum effectiveness with minimal noise level. The system was installed in a few hours and you would never know it was there. The pump is almost completely silent and in a place where you can't hear it even with the windows open. The installer spent some time explaining to me what he did, and if there was a problem, what simple things I could check before calling them out for service. Overall its was a great experience for a reasonable price, and my radon level dropped to almost nothing with the new system. I would definitely use these guys again if I needed another radon reduction system.

I can't say enough good things about this company. Chris explained everything in detail and was patient with my concerns. Brian came out an extra time to go over the outside placement of the vent. The tech who did the installation arrived on time, worked efficiently, and left the work area looking spotless. The customer service was excellent and the results of the mitigation beyond expectations. I recommend 5280 Radon Mitigation without reservation.

Great service from 5280 Radon. Affordable service in comparison to competitors, but not short on quality of installation or explanation. Flexible scheduling and timely with installation when onsite. Walked through our property, discussed the various options of installation to assure the best mitigation with the best appearance. Highly recommend 5280 Radon to anyone looking for the same service.

As a Realtor in West Metro Denver for 12 years, I have ordered many radon mitigation systems. 5280 Radon is my "Go-to" source for mitigation. They are responsive, reliable, and their pricing is super-competitive and simple. They don't play pricing games with upgrades and add-ons, just straight forward good service. I've had them install 4 systems in the last couple months, nothing but outstanding experiences.

Highly recommend 5280 Radon Mitigation. Chris and Bryan were VERY professional thru the entire process. From initial phone call to installation. The know what they are doing and it shows. They explained everything thoroughly and indicated if they have to come back out everything is under warranty. Can't thank them enough for putting my mind at ease that our Radon issue is now being addressed properly.

I called a few companies and the price was the same as 5280. What impressed me the most initially was how quickly they followed up on the qoute and the amount of time Chris spent explaining the system. The installers also were on time and even though it was more work they vented thru the garage. Very impressed with the workmanship of the system and I know that I received a competitive cost. Will recommend in the future. A small price to pay for piece of mind knowing that I dont have radon in my house.

After several bids, I had 5280 Radon come out before we put our house on the market. I had a choice as to how to vent the system without a price increase like everyone else had been quoting. We got to run up the garage rather than out the side of the house so now it is just another stack rather than an eye sore. The guys not only did a great job and walked me through the system, but offered to come out to MT if I needed radon mitigation up there!
