"Matt was awesome to work with! We found him after having some serious issues with another radon company. Matt was quick to respond to us and came to take a look at our system right away. After the first company we hired could not fix our radon issue (they came back again after missing a broken rubber cufflink around our fan) Matt returned and performed a thorough evaluation of our basement and current mitigation system. After only a few hours, Matt was able to find the best suction points in our basement. He took apart our system, created an additional suction point via brand new pipes, and installed a larger fan. The system ended up working flawlessly and the radon significantly decreased to normal levels within a day or so. We'd been dealing with this radon issue for months and it honestly seemed like lost cause but Matt was able to fix the issue with ease. We now have complete peace of mind and we're happy to say we can finally enjoy our basement again. Thank you Matt (and Steve!)!"

We signed a contract and will retest levels for verification before proceeding. I was very impressed with Chuck and recommend his services for any inspection issues."

"They were reasonably priced but I'd recommend skipping and saving yourself the heartache. I was having issues with the radon mitigation system they installed. After a few days of calling and leaving messages I had no response. Then we finally figured out when they installed the system it only received power when the light switch was on...instead of wiring it to run all the time. Still no response back from them and I am paying to fix the issue myself. Do not go with them."

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

FAQs for radon gas abatement projects in Windham, NY

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.
