"George and his entire company were amazing! George sat down with us and explained every detail of the work, and left us with material that gave us an education on Radon itself. This was very helpful for many reasons.. The work itself was conducted in an effective, clean, respectful and thoughtful way by his crew., and he came by to ensure completion and satisfaction. The crew even helped us with something adjacent to their job for no extra charge. I cannot recommend this company enough!"

"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."

"DO NOT USE THESE PEOPLE!!!! Marc Pressman came to my house and brought his looseleaf with him. He had all kinds of docs saying that he was the best. I took him down to my newley finished basement and showed him exactly where the water was coming from. He said "no problem, we are experts and can fix this guaranteed". He took my deposit and sent his team down. Michael was the man working on the job. Super nice guy, very clean and looking to do minimal damage to the floor ( he would be better off starting his own company). They installed the drain and the pump and told me my water problems were over. A couple of months later we had a couple of days of solid rain and the basement was flooded again!! I thought maybe the pump didn't work so I took the cover over the tank and it was bone dry!. The water never even went into the tank. Immediately I called the company and got a message " Due to severe weather conditions no one is available to take your call...leave a message." Three days later my message was returned . They sent someone to the house and he said ,well everything is dry now so I cant really tell where the water came in from. Lets wait till it happens again and then I"ll come back. Sure enough last week it rained like crazy and my basement was flooded again. Immediately I called Marc Pressman and he said I cant help you, you need to call the office. I told him I guess you only take the peoples money otherwise you cant help. So I called the office right away sent them pictures, and told them to send someone down asap so they can trace the water. Its been 5 days now and they never called back and of course the water subsided by now. DO NOT USE THESE PEOPLE!!! THEY WILL TAKE YOUR MONEY AND WON"T SERVICE YOU WHEN THINGS DON"T WORK!!!.... I WILL CONTINUE TO POST NEGATIVE REVIEWS AND REPORT THEM TO BBB AND CONSUMER AFFAIRS UNTIL THEY MAKE THINGS RIGHT."

FAQs for radon gas testing projects in Elmira, NY

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
