ARadon Abatement Services
I called 3 companies to ask about having a radom remediation system installed. When I first called to get information from Radon Abatement Services, John was in the middle of an installation. He explained that it would be better if he could call me back when he could talk without distractions, and he called me back within the hour. He assessed my situation over the phone, asked very appropriate questions about radon level, age of the house, layout, type of basement, etc., and immediately gave me a feeling of confidence in his knowledge and abilities. John also told me exactly how much it would cost ($800) and emailed me a written fixed price quote (as opposed to cost-based, which can fluctuate based on variations in the job). I was able to schedule my radon mitigation system installation within days. On the day of installation, Martin and his assistant arrived within 10 minutes of the schedule time, which I found impressive considering they had to commute around the beltway in rush hour. Martin did a walk-thru of the basement and exterior of the house to determine the most appropriate location for the pipe and fan. Once the location was determined, they did their thing without any issues. It took about 3 hours. My only TINY complaint was that I wasn't warned that the cracks were sealed with sticky stuff, and I stepped in it...maybe give customers a heads up about that. I have no idea if the radon system actually works at reducing the radon in the house because I have not had it re-tested yet. I hope to never need this service again personally, but I would definitely recommend Radon Abatement Services to family and friends.

Mr. Jim Humphreys provided an estimate for radon mediation that was competitively priced and consistent with other highly rated company?s designs.  Once I selected the bid from Radon Abatement Services we agreed to a mutually agreeable date and time for the mitigation system installation.  I should note, Mr. Humphreys arrived for each scheduled meeting within 15 minutes of the agreed time, and he went one step beyond by telephoning me in route to advise me of his expected arrival times.  Once they arrived and started the installation, it was immediately clear to me that they know their business, and that I had selected the right radon contractor.  The system installation was made in an unobtrusive location in my house, the workmanship was first rate, which actually provided for a good looking installation.  In summary Radon Abatement Services did what they proposed to do, on time and on cost, and the initial post mitigation radon test results show radon levels well within the government recommended safe levels for occupied residential spaces.

We got their information from our friend. When we were making an appointment, Mike gave us his professional advice based on the house details. They arrived on time and Mike's team is extremely professional and friendly. They did a wonderful job for us. We are really impressed and pleased with their work. Will highly recommend anyone who wants to do radon mitigation.

ABoulder Edge Inc
We are very happy with Boulder Edge and warmly recommend them. The company is professional, reliable, and of high quality. Our house was difficult to handle because the vent pipe from the basement was badly hidden in the walls. Boulder Edge was patient and work through the complications. Tom and team took time to explain all actions, and next steps. In every regard we are pleased with their service and work. Our home radon level is now about 0.6!

Mike and team were very knowledgeable and patiently answered all of my questions (and I always have a lot of them when dealing with contractors). They know their stuff and didn’t oversell or make false promises. I already had a mitigation system in place over my sump pit that came with the house, but it wasn’t adequate to service the multiple slabs that make up my foundation. Mike suggested a stepped approach to deal with the “hot spots” in the house and then re-assess whether additional action was necessary. They installed a clear lid over my sump and fixed the trap in my pit so that the existing fan was actually pulling suction on the foundation (and not the open drain from my exterior stairs). They also installed a second system that serviced two slabs and vented out through the back of the roof. Finally, they sealed up some cracks and holes around the foundations. Mike found a solution that was sensible from an aesthetics perspective as well as functional. The pipe runs through my entryway closet, and is as hidden and cleanly installed as I could have hoped for. We had a difference in opinion on how the finished roof flashing should have been done (more from an aesthetics perspective), but it’s on the back of the house behind the chimney so I wasn’t overly concerned about it. The system has reduced my levels to around 1pc/l down from a previous average of about 8 pc/l. So definitely within acceptable levels. I’m only a month in, so will continue to monitor over the next year to determine if any seasonal impacts require further action. I would definitely recommend them and plan to use them again if I need to (although I hope I don’t have to). If you are looking at this and don’t have your own continuous radon monitor, I recommend picking one up.

Very well. Mike, the president of the company, explained what needed to be done to correct our radon problem. The crew arrived on time, installed the system, explained how it all worked and left absolutely no mess behind. They arranged for a follow-up by a testing company to insure the system was working properly. Everyone involved was very knowledgeable and professional. We highly recommend this company.

I cannot say enough good things about how this went. During the initial phone call, I was asked a lot of questions about the living spaces, unfinished areas in the basement, etc., etc. We must have spent 15-20 minutes on the phone. Then I received their proposal, with specific information about warranties, estimated annual operating cost, etc. – the kind of information that helped me make an informed decision. The installer showed up on time and was simply awesome. He was professional, clean, and more than willing to explain what he was doing and answer my questions. It was a pleasure to have someone like that working around my home.

Ric did an excellent job. He definitely knows the in's and out's of Radon remediation and is a careful craftsman who pays attention to the details. I did recommend him to a friend and she was also very happy with his work. My Radon level in the living space had a 3 month average of 3 PiC/L with peaks as high as 5, and after remediation it fell to a seven day average of .27 which is roughly the outside Radon level.

John was extremely responsive.  He came out to look at the house a few hours after our first contact.  He was very professional and gave us a clear quote.  He answered all of our questions in a non-patronizing way.  His team came out and installed the system a day early (storm-related) and were done in a few hours.  No mess.  Very efficient.

John and his employees were very professional and responsive.  John scheduled the installation quickly and his his crew arrived on time and had it completed within 2 hours of their arrival.  They placed the radon mitigation system right where I wanted it even though it was not the easiest location to install it in.  Now all that is left to do is to conduct a post mitigation test to see if it is working properly.

D(202) 667-0707 SWAT Radon Mitigtn Washington D.C.
Poor communication and poor customer service. Worker was unprofessional (using inappropriate language; talking on phone) - I have children so this was much more of an issue that it otherwise would've been. There was no communication about the work to be completed (other than a basic sketch that didn't provide much context). I had no idea there would be a huge, unsightly monstrosity installed in a very visible portion of the back of my house. (The man said he probably could've put it elsewhere, but he basically took the easiest path (and didn't consult with me about it). Poor clean-up of job site; worker left behind a couple of large pieces of PVC. When I called to have the materials picked up, it became clear that they have a terrible customer service department and seem to not really care. I called and didn't receive a callback within 24 hours so I called again. Finally they said they could have someone pick up the materials the next day (which makes it three days after the job was completed). I emailed my agent and asked her to reconsider recommending SWAT to future customers. Everything about this experience is highly unacceptable.

Our Radon inspection report came back with a 12 pCi/L result, which we needed to immediately resolve.  I contacted John from Radon Abatement Services for mitigation services.  He was very professional and informative.  He asked me questions about my home and then was given a quote based on my description.  The work crew showed up on time and was very professional.  The work was completed in the allotted time and for the exact price quote.  I would definitely recommend to family and friends.

It was very professionally done.  The report said I needed mitigation.  The mitigation project (done by others) was very successful.

Recent Review: The system was installed and reduced our level from 5.1 to 0.6. Ken took time to explain the system and how to monitor it. The installation was clean and neat and the work area was left spotless. Scheduling was efficient and the process explained. Ken and has assistant arrived on time and after assessing the work, accurately estimated when the work would be complete. He respected our house by laying a drop cloth all along the walking path.

Recent Review: This is one of the best contractors I have ever worked with-professional, respectful and accommodating! Truly cannot not say enough positive about Mike Sr. ,son Mike and John. Needed to remediate radon for a home that is going on sales market very soon. Mike was flexible -adjusting to fit my crazy work schedule. That was very much appreciated! Then on the day of our appointment, my vehicle needed work and I was running behind schedule. Again Mike Sr. worked with me. When Mike, Jr. and John arrived- they quickly surveyed the location of the installation, explained again what was going to be done, and started to work. They worked efficiently, work was neatly done and clean-up was excellent. I would highly recommend this company- for their fair pricing, professionalism and efficient work. Thank you for an excellent job.
