Radon Abatement Services

Excellent service and responsiveness from A - Z. We managed the project from overseas and the company worked with our property manager and us to install and test. Highly recommended.

The head guy came over a week ahead of the service date, inspected the area where work was to be performed, and provided an estimate of the cost. He also brought up potential scenarios that could come up, and how they would be dealt with. The workers performing the service arrived on time; they had called to confirm the precise arrival time several hours before arriving. They were very good about explaining what they were doing and how they were going to do it. They provided an estimate of the time it would take to complete the work, which turned out to be spot-on, about 2.5 hours. When the work was complete, the foreman gave me a complete rundown on the work they performed and how the equipment operated. They did a great job cleaning up after they were done. When we used the follow-up radon test, we were surprised by the results. Our radon level plunged from about 8.0 pc/L to 0.4 pc/L, which is basically the level in the atmosphere. So to recap, the project was completed on time, on budget, and was a complete success.

The company representative explained the process over the phone and provided a cost estimate. The technician arrived on time and completed the work as scheduled. He was friendly and organized.

They arrived on time and got right to work. They were very quick. All the work was done very cleanly and with a minimum of intervention by me.

Radon Abatement Services was very professional through our entire experience. The person who answered the phone when I first called to request an estimate was very knowledgeable and asked the necessary questions to get me a quality estimate quickly. I received a proposal in writing that same day. Our work was scheduled within a week of accepting the proposal, and the installer called personally to confirm the appointment and any relevant details. He arrived on time for our scheduled appointment and did an excellent job with the installation. We are very pleased with this company. My only other comment is that we should have asked how long the installation would take because it took longer than I expected (about 4 hours) and that would have been nice to know for planning purposes. Definitely not the company's fault as I did not ask the question, but just some advice if you are planning to have this service performed.

A team of two workmen showed up at 9 am. The lead reviewed what I had discussed with the contractor and then began work. One workman drilled the hole in the concrete floor of the basement and inserted the exhaust tube. He then drilled a hole in the basement wall to run the tube out and up through the deck. He had to drill through both the deck and the overhang on the roof to run the exhaust pipe to a level that would release the gas exhaust at a safe location away from windows and doors. A small fan was installed in the exhaust pipe to ensure consistent flow. They sealed up around the hole in the floor where the pipe was installed, and sealed a number of small cracks in the foundation and floor so that the exhaust would be drawn from under the concrete pad. When the work was completed, the lead showed me the pressure gauge on the exhaust pipe that indicated that the system was working properly and what to check for on a regular basis. He then showed how they had hooked the fan into the electrical system and which fuse controlled the fan. They cleaned up everything and were on the road in about 4 and a half hours after leaving me two test kits and instructions on how and when to place them in the basement. The workmen were very professional and thoroughly knowledgeable about the work they needed to perform. They went to work immediately after arriving and worked quickly and nonstop until the job was done. It couldn't have gone smoother. And the results have been ideal.

I didn't have to have the work done due to the owner's honesty.

Radon Abatement Services did an excellent job installing a new radon reduction system in our house. The estimator was timely, John explained how the system would work and what would be involved and provided a quote in a timely fashion. The installer's were on time and did a great job with the installation. The work looks professional and the system is quiet.

The job was finished efficiently and our radon levels are down to acceptable levels.

Great experience. We had received two quotes prior to selecting this company. The gentleman who had come out to provide the cost estimate had literally done over 50 homes in my neighborhood, including one across the street, so he knew what he was working with in terms of what was underneath the home's foundation. On the day of the installation, Marvin and two other gentlemen arrived. They checked in with me and my husband throughout the process to confirm that we were aware of what they were doing, and to get responses from us during certain decision points in the process. They were professional, well-coordinated and cleaned up upon completion of the project. They even applied concrete over a small but unsightly plumbing hole that we found in the basement foundation. My husband and I would happily recommend them to others.

The installer arrived a few minutes ahead of time. He went about his work with no disruption to the household. When he finished in 3 hours he showed me the installation, explained how it worked and what to watch for. He was polite, cleaned up after himself and appeared to be very competent.

The installers were running a little behind in their schedule but other than that the installation was flawless. It took close to an hour and a half from their arrival until their departure to perform the services. Before the service, my radon measurements were above 2 and sometimes as high as 3.9 in my basement. I spoke with John Swett and he told me that a blower/fan in my attic should be all I need to get the readings down below 2. I was happy to hear that and John explained what would be done by his employees and that I would be getting 2 test kits to evaluate the installation results. Now, using my meter, the readings are in the low 1 to 1.2 measurement range. The 48 hour measurement reading was 0.4 as measured by AccuStar labs. I look forward to finding out what the long-term test reading is when the time arrives. I would highly recommend John's company for radon abatement.

Before finishing my basement, I needed to install a radon remediation system. I found Radon Abatement Services via Angie?s List and submitted a request for quote via their website. Within 24 hours John Swett called me to discuss my needs, and within another 24 hours I received an email estimate. The estimate was a one-page itemization of proposed work: Sub-slab ventilation system through basement floor or custom made sump cover out left side/rear wall of building to a radon fan and continuing up exterior of building to above roof line; sealing of sumps or floor drains if necessary; sealing of large cracks and slab to wall joint if necessary; and, for Angie?s List members, a complimentary long-term Alpha Track test kit. The estimate also has a bullet list of guarantee and terms, which answers many of my questions of what to expect. I accepted their proposal and scheduled work. On the day of installation, Mr. Humphrey arrived and spent a good four hours installing the system. I was very impressed with the care he took in everything. He made sure the pipe going up along the house was straight and neat, the fan was level, and the pipes inside the house as unobtrusive as possible. When he was done, the system was a thing of beauty. There is just something to a quality installation that you can see, where all the parts fit together so well the result looks as if it?s sprung fully formed and always been there. At the end he walked me through the operation of the system, how to read the monitor, what to do if we have to ever cut the seal to the sump pump cover, and how to use the radon detection kit he left behind. I was extremely happy with the work and can heartily recommend Radon Abatement Services and especially Mr. Humphrey.

Overall, I was very very pleased with the installation, the installers, the equipment. All staff were professional, communicative, helpful, friendly, and very neat. Everything was cleaned up. Would recommend them with no hesitation. Thanks!

The overall installation was excellent. The crew came exactly as scheduled with all the equipment and supplies which they need. They worked both efficiently and effectively and completed the installation within about 2 hours. The installation was very neat and clean and complete. The work area inside and outside the house was cleaned up. Finally, they provided instructions on how to operate and maintain the system.

Radon Abarement Services accommodated my limited schedule due to health issues and arranged for an expedited appointment over the phone. Mr. Jim Humphreys arrived on time, worked four hours to install the system, was professional and competent and tested the system for me before cleaning up and departing. He left me with both short term and long term test kits, as well as a guarantee that the radon reduction system would bring my radon levels to below 2.0. This was not an easy install, because it involved drilling through the framing boards over the basement cinder blocks to access the garage from the basement. I was very pleased with the entire performance of this company.

Owner, John Swett, came to look at my setup after my house tested very high for radon. He told me what his guys would do to remove radon from the house, described the process & the system in great detail, spoke about two possible options, depending on what they found under the ground. He said that most likely, there would not be gravel due to the age of my house (100 + years) and the cost if that was indeed true would be slightly higher ... they had to dig two holes in basement floor instead of one. (I think I have that right ... Not exactly my area of expertise!!) The workmen came right on time, did a perfect job, were personable, professional, easy to have around, and cleaned up after everything. Truth be told, this is the kind of workers I wish I could find in every home repair/improvement category. After several days, I retested with the kit provided, sent it off to the lab to be tested. The results were excellent. Radon levels were almost non-existent. When I called John to tell him, he already had the results as well, and though he was quite pleased, he didn't just take the money & run. He told me the importance of retesting in the fall. This guy represents Integrity with a capitol I. I am truly impressed, and that is not easy to do ;) I HIGHLY RECOMMEND THIS COMPANY WITHOUT RESERVATION!!!

The process went very well. John Swett was exremely helpful and knowledgeable when I called and very reachable. We devised a Plan A and Plan B in case Plan A didn't solve the problem. Plan A was very successful, with very low levels of radon in the reteting, well below the guaranteed results and well below recommended limits. John knew the Barcroft neighborhood from prior work there and the typical foundation designs there from the 1950's.The company was busy so there was a two week wait for the installation. But they came on time and finished the work in a very timely manner, and very cleanly and with minimum intrusiveness.

The company came out and replaced the pump as promised. Market price.I am very pleased with the results and the service.

No glitches, The system works.

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.

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.

They were prompt and professional. They did what needed done and did it neatly and we were pleased.

This was as close to perfect as it gets with a contractor. The three-man RAS crew showed up earlier than expected (traffic on the beltway wasn't bad). They quickly got to work and were completely finished in less than an hour and a half. All three were true professionals who knew what they were doing and did it very well. They also cleaned up the job site after they were finished. I highly recommend Radon Abatement Services to anyone who needs a radon mitigation system. The owner was very responsive to my email request for an estimate and worked with me to schedule the work quickly. This is a first rate company. They do not do radon testing so they do not try to sell you more than you need.

John came to the house assessed what needed to be done. Knew exactly what he was looking for. Told me what the cost would be and why. Promptly Sent a detailed estimate. His crew arrived two days later draped the floors in my home,were professional, respectful and efficient in their install of the abatement system. Processed my payment and left. Couldn't have smoother. So glad we had this done.
