"I cannot say enough about my experience with Family Home Inspections, Inc., Mike in particular. Not only did he respond to my email post within 3 minutes of submitting it (pretty late in the evening), he must have recognized the horror in my voice because he agreed to meet me that Saturday (to accommodate my schedule) even though he had a family function to attend. He said the inspection usually takes an hour: maybe a little longer depending. I knew this was going to be take more than an hour as, upon arriving at my house and looking at the roof, outcomes the ladder and he starts looking around every window and the wood roof to identify all the ways that water could get in. Cut to 3 1/2 + hours later thinking we were done, I asked him to investigate a few additional locations I hadn't originally thought of. And without hesitation, he went to his truck to grab a different piece of equipment and thoroughly documented his additional findings. He makes no extra money whether he is here for 1 hour or 5 (except maybe a few dollars if he thinks an additional sample or 2 is absolutely necessary), his only concern was making sure he thoroughly checked the whole house and I was satisfied that all the areas I was concerned about were covered. Mike was very professional, thorough, friendly, frank and honest about the job ahead yet reassuring in the process. I would recommend him 1000 times over should you find yourself in the same awful predicament as we did. Leah D."

FAQs for radon gas testing projects in Sandy Hook, CT

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.
