"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

"Last year, we sought three estimates to take care of the visible mold in our attic. Of the three estimates, Enzyme Life Sciences (ELS) set themselves apart for two reasons. First, their price for the remediation alone was less than their competitors – hundreds of dollars less. Second, ELS does not perform repairs as the other companies did, which gave us the flexibility to do repairs ourselves or find our own contractor to perform the repairs at a price we found reasonable. ELS was more than happy to help us understand what improvements he thought we should perform on the attic and we made those changes after the remediation at minimal additional cost. ELS was prompt for every interaction and responsive with phone communication. I felt bad for Mike, our ELS remediation expert, as he came to perform the work at the height of last summer’s heat. He came down from the attic after the remediation sweating but maintained a positive attitude throughout the job. He even went above and beyond to take away some moldy insulation that I had piled up in the attic to dispose of myself. Mike left us with clear directions to run the whole house fan and dry out the stain remover. Minor staining remained after the service, which is not uncommon, but Mike spent as much time at our house as was necessary to ensure that the mold was dead. We recently sold the house to reduce our commute to work. The buyer’s inspector noted the remaining mold staining in the attic. Mike was extremely professional when I called him for help. He reviewed the inspection report and recognized the staining. He could have demanded an air sample to prove the accusation of live mold, but he didn’t because he cared about me, his customer, and our interest in moving through the sale of our house. Instead, Mike offered to come back out to the house and perform another treatment at no cost, which gave the buyers confidence that he was willing to stand behind his work. He also confirmed to our buyer that his guarantee would transfer to them, with a few reasonable expectations like “please do an air sample next time so that we know that there is indeed a problem.” In the end, our buyer was happy with ELS quality and customer service and we moved through the sale with no further questions or concerns about the attic."

"Matt responded quickly and did a great job. The flood was just days before Christmas, but he put in all the time and effort necessary to get the job done right. Matt is a very nice guy and we were comfortable having him and his workers in the house while we were at work. Our insurance paid for his work."

FAQs for radon gas testing projects in Windham, 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.
