"Matt and his crew of Jacob and Christian went far above anything I expected. I called Matt on Saturday afternoon because my sump pump broke and basement had water everywhere. Within 5 minutes of submitting request for a quote he called. Within 30 minutes he was here assessing. Within an hour he had dryers and dehumidifiers set up. He called to check in on Sunday and was here Monday morning. Tuesday morning Jacob and Christian arrived and emptied everything that was damaged by water (and more). They filled a giant dump truck. They were so polite and careful. Right down to the sweeping! I felt like I was dealing with service the way it was years ago. I could not have asked for anything more."

"After Healthy Homes did such a great job on my rental apartment, decided to see if they could help me with the cigarette smell in my car. Was sold a small handheld fog machine and some Un-Odor product. Fogged the entire interior of my vehicle, sprayed the product on all surfaces. After washing the windows with Windex and wiping everything down with a dry towel, the car was free from odor and looked and smelled clean and fresh! Fantastic Products!!!"

"We started with a free estimate. He arrived on time and answered all questions in minute detail, and clearly. We chose him over another company and have no regrets. The service could not have been better. The work was done on the days promised and gave us photographic updates as the work was done. The workers were neat and clean. The work would have been completed one day early but for the fact that one supplier sent a wrong part, which was promptly corrected. DeWitt was personable, friendly, extremely knowledgeable and very informative. We could not have had a better experience. We recommend this business highly."

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.
