David Silver, IEP/LMA; holds New York State licensing as a mold assessor, he also has first hand personal experience with molds affecting the health of loved ones in not one but two homes. He has undergone the process of water damage and mold discovery countless times and had his own home undergo extensive demolition, removal of molds, cleaning and rebuilding. He brings a much needed level of empathy to those who are embarking on this kind of endeavor. He recognizes and is sensitive to the high level stress and financial cost this can bring.

"David was not only proficient and professional with a high level of expertise but had such deep heartfelt compassion and empathy for my situation. It was a refreshing and comforting experience to work with David. Given all the unknowns, David's patience and ability to educate me on the potential outcomes really helped to settle me down. I like to know what I'm facing and I feel like David and First Stop Environmental gave me life affirming choices. Thank you."

"Assessment done for mold found near crawl space. Gary was fabulously helpful, even helped move some boxes out of the closet where the crawl space entrance is. He took the time to explain everything, had a sensor that can detect moisture through the wall (drywall in this case), had helpful suggestions, was very thorough in checking the nearby rooms and garage with the sensor. And he's just a nice man, a mensch. I would absolutely hire him again if needed. Thank you, Gary!"

"It went great. Alex brought the test kit to my house on a Saturday morning (!) as planned at the time he said he would arrive and placed it in a good position. He gave me clear instructions for the test. They were very easy to follow. He emailed information about the test beforehand and also gave me status on the test results. He also gave me the test report as soon as they were available. I did not have to follow up at all. I am very pleased with the service provided. I would definitely use him again and recommend him to anyone."

"My house had excessive levels of radon in our lower level. The Lance Dorfi team installed a pump to pump out the radon and release it up above the roof of the house. Since then, radon levels in that part of the house have been very low, so the problem was resolved. The work was done on budget, and they did an excellent job with scheduling and customer service. I recommend them for dealing with radon."

Radon Detection and Reduction questions, answered by experts

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.
