"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."

"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."

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."

Radon Detection and Reduction questions, answered by experts

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

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.

Through air sampling devices and surface swabs in key areas of concern.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.
