He is committed to doing his best for his customers and giving them the best sense of the home they are about to potentially purchase.

"Chuck and Noah, are amazing to work with. They communicate extremely well and are honest. They did a home inspection Saturday morning for me. Thankfully I asked them to do a full septic inspection, not just a dye test. They found the septic system, needing major work. To the point, my bank won't approve the loan. the house failed before they even got inside it. When trying to explain to the home own, (who is also the listing agent) what was wrong, and why it needed to be fixed. All this lady did was rudely speaking over him, to the point she was mad at him for finding it. She would ask why it failed and as soon as chuck would begin to explain, she would start yelling over him, how it was fine. She must of ask half a dozen times for him to explain, for her to start arguing as soon as he spoke. I don't know how Chuck was able to be so calm and professional. I would have hit the lady, getting in my face like that. Chuck, was instead calm,kind and professional. "

FAQs for radon gas testing projects in Valhalla, 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.
