ARadon Abatement Services
Jim Humphryes of Radon Abatement Services installed radon mitigation systems for my single family home in Sterling.  The original/prior radon level was 5.8 in the basement, I ran couple of short-term radon testings a week after Jim installed the system, and now the reading is 0.4 which is normal.  I strongly recommend Jim and Radon Abatement Services for any radon mitigation work.  Jim and John are very professional, the price is very reasonable at $800, and quality is exceptional.  Best of all, my radon level is now normal, and moldy smell in the basement is gone.  I am so happy to use their services and will recommend them to all of my friends and neighbors.  5-star company.  Keep up the good work.

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.

Radon Abatement Services (RAS) had certain, correct radon tests performed, demonstrated sound experience and good judgment in developing radon abatement plan, demonstrated good workmanship, dealt intelligently with special problems that arose, and stubbornly refused to give up its efforts to solve my radon problems.  An honorable, intelligent, experienced and highly capable company.

AReliable Radon
Reliable Radon was able to schedule quickly, and Robert did a very neat job activating my existing passive radon pipe. It was a challenging job, with the pipe tucked in a corner behind an HVAC unit, but Robert did it very cleanly. The included re-test gave us a high reading, so Reliable dropped off another test, which showed that the actual radon levels had been remediated quite well by the work.

ARadon Abatement Services
Outstanding.  Could not have asked for anything more. We had been experiencing high levels of Radon in  our basement area. I measured levels above 6 pCI/L using a a very good electronic radon detector. I located Radon Abatement Services on Angie's List and received an on-line quote from them after answering a number of questions about my home. The quote was very reasonable and well within the range that I expected to pay. They met all of the qualifications you should look for in hiring a radon abatement service. They do no radon testing to preclude any conflict of interest with their clients. The installer  was outstanding, knew what had to be done and completed the installation to my satisfaction in about 6 hours for the quoted price. I'm pleased to say that my radon level has dropped to 1.2 pCI/L since the system was installed a little less than 2 months ago. If you need a radon abatement system definitely call Radon Abatement Services.

United Radon Sciences were great. They put up two fences and they track the radon. I chose them because of the Big Deal. They were quick and responsive.

I highly recommend Ric for his ability to think outside the box to solve a complex problem that I had. We were told it was almost impossible to fix but Radon Installers saved the day. After looking around for 40 minutes Ric figured out how to install the migration system. Not only were the radon testers who came by afterwards to retest my radon levels impressed with his work but my home owners association took his business and want to use him for any other radon problem that may arise in the future. That is QUALITY work.

ARadon Abatement Services
I met the team at the door. Walter the team leader presented me with a business card and introduced his other team member Mario. They had their own foot covers to protect the floors and were so very courteous. Walter assessed what work had to be done ... this was after John Swett the owner had been to the house previously to provide and estimate. Walter explained every step of the way on what they would be doing ... how the system would look outside of the house and where it would be placed. They worked very hard and diligently with smiles on their faces. I knew they had a very long day and I was their last appointment for the day.  Walter and Mario finished the project had the entire area cleaned up and were just great guys. Once completed, Walter went over the entire system to show how it worked. The electricians that conducted work in our house prior left electrical wires hanging out of a box and the box on a shelf. Walter happily put the box back in place once it was discovered. The work started a few hours later than I had expected but seeing how much work goes into this ... I was not offended as anything can change on a job. All I can say is a great job ... well done!!!

AEnvironmental Testing & Research Laboratories, Inc
That was excellent. That worked really well. It showed that it was negative, which is good. I had it tested by a different company before and they found radon. The builder put on an active radon fan system so I hired this company to do a post radon test. They were excellent. I’ll give them a top rating. They were prompt. I had the lab results within a week.

Mr. Parry of United Radon Sciences was professional, thorough and punctual. When I forgot to set out the box for him to pick up he even came back the next day, without any hassles! He explained the process to me so that I understood exactly what was happening during the test and answered all of my questions. My husband and I decided to do our radon test after purchasing our house and we are so glad that we did it with United Radon Sciences!

ARADON TESTING
I did get it off of Angie's List. They came just before the 4th of July and set it up, and they came on time and everything and everything was fine. A nice woman came, and then she came back picked up everything and then, by that afternoon, I had the results. I just called one person and I don't know about the price but it was fine. I didn't check it out because it was hard to find anybody. Most of them put in the device that solves the problem of the Radon and the first company I called didn't do the testing. A couple of them said they didn't do testing, so I was just glad to find them. They were here exactly when they said they would. I had to leave earlier and so I called them and asked if they could come an hour earlier, and they did.

ARadon Abatement Services
Professional from beginning to finish of the job!!  Installed Radon system from the basement and had it run outside the house on the side corner where the system is not noticable.  Technican was quick but thorough and cleaned up after himself.  He explained how to monitor the system and showed me everything he did.  I have told my neighbor about Radon and that they should get their home tested and referred Radon Abatement Services to them. True professionals!!

ARadon Abatement Services
During the first visit, my property was inspected, an approach for radon abatement was recommended, and a cost estimate was provided. During the second visit, the system was installed.  The work was performed very skillfully and the area was cleaned afterwards. Two radon test kits were provided for post-installation testing.

The guy who came out, worked within my schedule,  was pleasant, arrived in the time frame agreed upon, explained everything, and came to pick up the machine that tests the Radon within my schedule too.   I was very happy with the process, and the big deal.   No Radon in my house.

AFerraro Real Estate Service, LLC
Michael Ferraro designed and installed a radon mitigation system. He surveyed the home and installed a quality system that looks great. Our home in Leesburg had an average radon level of 12.  After Michael installed his system we have an average of 0.50. Highly recommended.

Kevin was very responsive on providing a quote and answering our questions via text. The price was very reasonable and payment was easy. He arrived for the home inspection on time, was very personable and easy to talk to. Kevin provided a very professional-looking report with pictures and detailed descriptions of potential issues.

ATarget Radon Mitigation
Scheduling was simple and I had a very informative, low pressure initial call. The crew was able to come out only a couple days later, and were on time, efficient, friendly, and informative. They replaced the radon fan and gave me a professional review of my overall basement situation. Great experience!

Recent Review: These guys did a great job and were professional, polite, efficient and punctual.  When we bought our house we had high, but non-actionable levels of Radon, around 3.8, in the finished basement.  My kids started playing in there more so I bought a radon monitor.  Some days we had radon in the 2s and other times it would jump past 4.  We hired these guys to install the sump pump radon mitigation system, but my wife thought it was worth paying the extra amount to do a system where the pipes would run through our garage attic/roof to avoid having a big pvc pipe running up the back of our house.  Things seem to be working great, with our radon monitor consistently reading below 0.5, which I believe is roughly the level of radon outdoors.  Pretty pleased and happy I don't have to worry about my kids playing down there for extended periods of time!
