5280 has to be the best. These men are quick, efficient and know what they are doing.
They put the system in the most inconspicuous place and were happy to do so.
I didn’t think installing a radon removal system could turn out to be an «enjoyable
experience» but because of their attitudes, it was!

True professionals. The first question you should ask your provider is if they are certified! After another provider (who has great Unilocal reviews-​lookout!) danced around that question, gave us what I suspect was a falsely high reading after a second test came back 3 points lower-​and was generally unprofessional, finding Chris and his team at 5280 was a huge relief. They were not pushy, gave us solid advice and were knowledgeable, certified professionals who take pride in their work. Would definitely recommend 5280. Be careful out there, radon mitigation is the Wild West!

I found 5280 on Unilocal,and they had very good reviews, so I contacted them. They were very professional and helpful in answering all the questions I had. They were also the cheapest among all I contacted. I am very satisfied with the job they did. I highly recommend them for Radon mitigation.

Reasonably priced compared to other vendors. Showed up on time. Most importantly, the intervention reduced radon levels to below the suggested threshold.

I contacted contacted a total of three companies to install a mitigation system for me. the largest one said they did phone quotes but since my house is brick they could not guarantee the quote because of issues they might run into and without coming out could not give me an option of installing a system that would not be unsightly. The other one sent me an e-​mail in reply to my e-​mail and told me to call them. Chris quickly called me back and Brian came to my house, looked around at places to put the system, went over each option with me. I immediately scheduled an install date. He came out two weeks later and installed the system He showed up on time, were very efficient and cleaned up. I have not used my radon test he left but I don’t expect any problems. A great local businesses.

Chris emailed us a same-​day quote, which helped us close our home sale. We ended up giving the buyers a credit for the installation, so I’m not sure who did the work but I hope it was 5280, they were very responsive and professional.

I found 5280 Radon on Servicemaster. They came out to the house, looked around gave me options on where to place a system, which no other company did. Other companies asked me to take measurements for them, and gave me a price over the phone!
After getting the initial test back, 5280 Radon came out and installed a mitigation system. They were very professional, on time, and very reasonably priced.
After the system was put in, I sent the tests in for the new Radon numbers. There was an issue with the mail, and my test did not arrive at the testing facility on time. Chris took it upon himself to have a testing company come to the house, re– do the testing over48 hours, and when it was done I got the results that afternoon. Chris went above and beyond to make sure I was happy with my system. The numbers were fantastic! I would highly recommend 5280 Radon.

Couldn’t have been happier with these guys. They work really hard to make sure you’re happy. Use fair and upfront pricing. And are extremely responsive on phone calls, emails, etc.
I had previously had radon mitigation installed when my home was purchased. We needed ours re-​routed for a deck project. They were super thorough, presented several options, and helped us do some additional testing to ensure our re-​routing wouldn’t be adding to an existing radon problem. After we got test results back they came the next day and did the project beautifully. Well… as beautiful as PVC attached to a house can be :)

This company contacted me within a couple of hours requesting a quote — Check.
They were at my home that afternoon to provide explanation of their service and estimate — Check.
They spent time discussing the options for the best installation — Check.
They didn’t tack on additional fees beyond similar low priced initial bids we received, the price was the price — Check.
They came back in two days and the service was completed within the time quoted — Check.
They spent time explaining what to expect after installation and how and when to use the follow up self test — Check.
They were neat, cleaned up after themselves and are very friendly — Check.
If you want a quality job, for an fair price then get in touch with 5280 Radon and you will be pleased!

Having been in Real Estate for 35 long years, I am always looking for good contractors. Bryan Coy, at 5280 Radon is one of the best. Honest, hard working and very knowledgeable.
I have used Bryan for quite a while for radon mitigation.
They are affordable, and offer a guarantee, so it is easy to order it and not have to worry.
I have had him repair older systems too, and he has been on time and finished the job. If an older system is not drawing 1 atmosphere, it is not working very well and should be checked.
Highly recommended.
