He showed up early and took the time to explain the whole process to me. He worked efficiently and had the job done in less then 2 hours including cleaning up after the job. He then took the time to explain how the system worked and how to maintain it as well as how to retest the radon levels.

Very good regarding the installation. Billing and payment : I was told initially they accept credit cards but was required to pay by check This should be changed! also, AL should provide a SEPARATE feedback section for reviewers to comment on just that topic.

Above and beyond for our job. The technician had to drill through a concrete wall (no small task!) to route the PVC to the outside. Very clean and professional! Radon levels were averaging around 8 pCi/L (before the install) and are now at 0.2pCi/L!

The guys were prompt and friendly, and even uncovered a crawl space in our new house that we didn't even know was there. The device meter was explained to us, and we happily received our radon results shortly after. All is well and we would definitely hire them again.
Description of Work: We purchased an old house with high radon levels. Accordingly, we needed a radon mitigation service.

John responded to my call within minutes, quoted a price on the phone, and scheduled the work for the following week. John's tech arrived on time (he called ahead to make sure I was ready) and explained what he needed to do. He showed me his test setup and confirmed that the system would work as expected. The work was completed quickly and he cleaned up afterwards. The results came back as 1.8. I couldn't be happier.
Description of Work: We are selling our house in Shrewsbury and the buyer required a radon test. Unfortunately, it came back at 5.5 and needed to be mitigated. My realtor recommended John Spokis at Radon Systems LLC. I checked him out on Angies List and saw the great reviews.

Our appointment was for 8AM and a 7:45, the door bell rang. The technician introduced himself and we took a look at the area. He assured me that there would be no problems, told me how long he would be there to complete the job. Once finished, he showed me how the system operates, where it was located and what we needed to do next. Everything went exactly as planned. No issues. No call backs. No worries.
Description of Work: During the sale of our home, the radon testing showed significant amounts of the gas and a full remediation was necessary, After speaking with referrals from our real estate brokers and having other companies visit for estimates, this company was the clear choice not only on price, but a quick response and prompt service.

Very easy to book an appointment. The person came and did the estimation seems knowledgeable. He tried to find the best spot to hide the system out of sight. On installation day, the installer showed up on time. He has been briefed and knew exactly what to do. The work took about 3.5hr, slightly longer than he originally estimated. The fan used is very quiet. I'm satisfied with the result, also appreciate he took effort to protect carpet in my finished basement.

Excellent. Just as described. Great responsiveness, excellent installation, good followup. Charged the standard price with small fee for much more aesthetic internal piping. Another individual wanted $1000 more and did not even understand what I was asking for when I asked if could be piped internally. One caveat: they are not electricians so possible you could need to have one on hand to complete power supply to unit, depending on your basement configuration.

They installed a fan in December 2016 and we re-tested. They had guaranteed a level of 2 pCi/L and it came in higher. They came back in February and did some additional work at no cost and we will retest. They were friendly and very professional. We would definitely refer them.

It went pretty well. A technician came out, on time, and did the work in an efficient, professional manner. The technician was polite and agreeable, and cleaned up thoroughly when he was done. Unfortunately, the test they gave me to run after the work was done showed the radon levels were still too high, so the owner of the business came out himself and added to the mitigation system, again doing a great, professional job, then left me with a couple more test kits. Those tests both came back with very low radon levels.
Description of Work: I needed radon mitigation for my home.
