We also appreciated how Tim kept us updated via email and text regarding our appointment. He is very easy to communicate with.

I recently decided to tackle our radon levels and purchased a monitoring device. Initially, I found…read morethat the readings fluctuated between 2 pci/l and 4 pci/l, especially with the basement window open. After a heavy rain, I was alarmed to see the levels spike to 9 pci/l. Since we have a room converted into a remote office in the basement, resolving the radon issue became a priority. After doing some research, I discovered that Ric had a remarkable number of 5-star reviews compared to other companies, so I reached out to him and set up an appointment. Ric showed up right on time at 8:00 AM and got straight to work. The first thing he did was identify the best spot in our unfinished basement for drilling a hole. He chose a discreet location behind the laundry room door, ensuring it wouldn't be noticeable. Ric then carefully brought in several buckets of gravel and soil under the slab, installed a white PVC pipe, and extended it into the garage. From there, he routed the pipe up into the attic and out through a small hole drilled in the siding of the house. He worked diligently for six hours and did an impressive job. Ric made sure to clean up thoroughly after finishing, and he sealed the slab crack with specialized radon chalk. The next day, with the basement door and windows tightly shut, I was thrilled to see the radon levels drop to sub-zero. I monitored the readings for three weeks, and they remained consistently low. I can't believe Ric doesn't have even more 5-star reviews; he truly did an outstanding job!

Tommy from Atlantic Real Estate Services installed a radon mitigation system in my home. I was very…read morepleased with both the system and their professionalism. I would strongly recommend this company. I contacted several NRPP certified radon service providers, and Tommy's initial response stood out. He followed-up with both a phone call and an email, asking detailed questions about my home. He also said that he had installed a radon system in a house on my street, which told me he stood by his work. Tommy visited the house to provide a free estimate, and he found that we happened to have a "passive" radon mitigation system which the previous owners had apparently installed. Tommy took a day to think about the project, and he offered two estimates: one to convert the passive system to an "active" system, and another to install a new system altogether. I appreciated that Tommy carefully evaluated my house, to the point that he found the passive system and offered that cheaper conversion option in addition to the altogether new system. We ended up going with the new system to avoid any unexpected complications, and because we knew the new system was fairly priced. I needed the work to be done quickly and during a specific time period, which Tommy accommodated. Tommy and his crew (his father-in-law and brother-in-law) left the house the way they found it, and the radon ventilation gutter on the outside of the house is as aesthetically pleasing as possible. As far as post-testing, they left a monitor in the house for a couple of days, and then they sent me results which showed a significant reduction. In addition, I also own my own radon monitor (an Airthings), which had shown an eight-week average above 4.0 before the system was installed. Within days of the radon mitigation service being turned on, the average had gone down to just above 1.0. These guys were a pleasure to work with and talk to, they offered a fair price which I ran by other contractors, and they did good work which I independently verified with my own monitoring device. I fully endorse Atlantic Real Estate Services.

John thought through the situation effectively, identified a good spot for and installed a Radon mitigation system and did some other sealing work in the basement. Radon levels dropped dramatically after he finished and are now consistently way below the 4 pCi/L level that requires mitigation. I would strongly recommend him if you have a Radon problem.
