"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."

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!"

Radon Detection and Reduction questions, answered by experts

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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).

Mitigation reduces radon levels, protecting your health and complying with safety standards.
