"The installer (Davis) arrived on time, installed the system in about two hours, and showed me everything I needed to know about the system. The “before”and “after” test results were right in line with my own test measurements, which I took with a portable radon detector. The radon level dropped to a safe level after the system was installed, and that level has been maintained since it was installed in July of 2020, about 10 months ago. Overall, I was extremely pleased with A & R and I highly recommend them for radon mitigation work."

"Radon mitigation isn't cheao, Especially if you are treating well water and basement air. Because we were doing both we got a discount. They showed up on time, worked quickly and performed final tests."

"Fernando was very accommodating when scheduling both the initial meeting to provide an estimate and to work on the job. He arrived promptly both times and his quote was on target and did not deviate after the job was completed. The area of the basement wasn't completely cleared for him to start work when he and his son arrived, but he even helped to move things. Both of them kept things neat and clean, which made it easy for them to clear out quicker with no mess for us to pick up after. I'm picky about installation and didn't want the utility side of the house to look like an industrial area, so Fernando was able to install the exhaust up to the roof alongside the downspout. He also answered any questions on his the written proposal and his price was as stated for the work that was needed for my particular job. We needed 2 locations in the basement floor where they had to install PVC pipe to draw out the radon to a single fan attached to the outside of the house, that exhausted up to the roof. Really clean install. Also got another test kit from him, so that we can test for basement radon levels within the next 2 weeks to see if levels have been reduced to below the maximum allowed. Fernando said he will come back should we need any adjustments and advised us to remember to call him for annual service. His company is listed by the CT Dept of Health as one of the few qualified radon mitigation professionals as of July 21, 2016 - there's only a total of 6 qualified in Fairfield County, so that's definitely a positive sign that we selected the right guy for our job."

"Spoke to Mark who dispatched a technician to check out water situation. Tyler was very thorough looking over current water softener and recommending an additional tank to remove rust and other impurities. Additional tank installed next day by Tyler, who then spent a lot of time testing to ensure water was clear. He returned another time or two to fine tune the process and to make sure I was pleased."

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

FAQs for radon gas abatement projects in Madison, CT

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
