"Olivier was terrific. He was incredibly thorough and left no detail out of his inspection or his report. He took the time necessary to inspect all elements of the inside and outside of the home, he was patient in explaining what he found, and he was able to put all his comments within a helpful perspective. I would recommend him 100% and would use him again without hesitation."

"Phil was excellent! We are first time home buyers. We hired him for general inspection and oil tank sweep. He arrived on time and was pleasant to deal with. He was through, precise and took his time to explain all the things that needed immediate repairs and that were hazardous in the house. He did not rush through the inspection and tested all the electrical and plumbing, attic, boiler etc. He even checked the shingles on the roof and questioned the seller as to why they were different colors. Also, he advised us to check that the sellers had all proper permits for the renovations done on the house, which we did not know we had to do. Phil sent us a very detailed report within 2 days with digital photos showing all the repair work needed to be done on the house. He helped us by providing honest feedback despite the seller being present at inspection. In short, he saved us from buying a home with major repairs. He also honored the Angie's list coupon. We are very glad that we hired him and will definitely use him again. We highly recommend him!"

"I hired Andy to inspect 2 separate houses I was interested in purchasing. Being a first time home buyer, I was very cautious and had a lot to learn about home maintenance, repair and what to look out for. Andy did a great job. He walked me through all aspects of the home inspection, he explained everything clearly and answered all my questions. He is extremely thorough, testing every door hinge, window lock, electrical socket- no stone goes unturned. I would definitely recommend Andy and Poseidon Home Inspection, and I would no doubt hire him again."

"As first time home-buyers, Chuck made the inspection process a pleasant one. I'm a bit of an anxious person who asks a gazillion questions in one breath. Chuck dealt with that better than most, he took the time to inform me of what he saw every step of the way. He arrived early, worked on the outside while we waited for the agent to open the house. He checked every room thoroughly, top to bottom, I mean this guy was like looking for any possible thing that could be wrong. This made me feel very secure of my investment in him and his time. The best part is he used the device to check for any signs of water leaks!!! my biggest fear is a water issue and mold, so this certainly put me at ease. I especially loved his reaction when he saw the foam insulated attic! he was so proud - and having an A Grade home inspector that proud meant everything to us!! he also set up the radon testing all reasonably priced. The report arrived within 24 hours, clear, coherent and professional. This guy is awesome, knowledgeable and we especially appreciated his fantastic sense of humor through the process. He is well-rounded and knows more than just home inspections, he knows the market and he brings all the right connections in Orange County, NY. Thank you Chuck!"

FAQs for radon gas testing projects in Chester, 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.
