Get matched with top radon gas testers in Nashua, NH

"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"Marcel performed a flawless installation of a Radon Mitigation system in my home. He thoroughly explained and shared testing results as he proceeded with the installation. He continually checked and rechecked his measurements and cuts making sure everything was level and plumb. I'm a very meticulous customer and I was completely satisfied with my new system. He left an instrument to monitor my radon levels for a few days just to be absolutely sure that everything is performing as it should be. If you need Radon Mitigation...I HIGHLY recommend Airtight Radon Solutions."

"Jon was incredible. He inspected the entire house, from attic to basement, for moisture with a special instrument that allowed him to detect what was behind the walls. He found that the basement was just above the maximum acceptable dampness - and that there was mold on the wood paneling, the kind of mold that makes you sick. He explained that the mold in the basement could easily travel to my bedroom located on my second floor. He said that this was a job I could handle myself, and told me exactly what to do. He would not accept a fee for this consultation."

"Although my relationship with ARM started a bit rocky, in the end I was very happy with the service provided. After a ARM technician replaced a fan, the noise level in the surrounding rooms increased to a point where I wondered if I could sell the house. I got the impression from the technician who installed the fan and was told by another company's technician there probably wasn't anything I could do. But, Mike G, from ARM, was able to lower the noise to a tolerable level by reducing the vibration from the attached pipe by making small adjustments including re-positioning the fan, removing old clamps and adding foam. He patiently answered all my questions and explained what he was doing throughout the diagnostic. Although the noise problem was resolved, the radon level was still 10.8 pCi/L so ARM returned (with the original technician and Keith to add a second suction point. . I was very happy with their work. The pipes were placed in a way that is an unobtrusive as possible, are securely fastened and as I learned, have the right pitch. Before the installation, Keith explained what they did to determine where they thought the suction point should be, and after must have been a long day for them, made me feel it was important that all my questions were answered. My radon level is now .6 pCi/L! My only complaint is that it takes a long time to get appointments and for two of the visits they were a few hours late.. The cost of service is for the 3 visits which were 11/9/18, 12/26/18, and 1/30/19 and includes the cost of the fan."

"The two techs were very professional and courteous. They installed a high performance radon fan and 3" pvc pipe with two different points of extraction in my basement. They had to work partially in a crawl space which made the install more difficult. They cleaned up all debris and left the work areas immaculate."
