"Lenny and Lisa are great. During the demolition phase, Lenny took great care to cover our hardwood floors and cleaned thoroughly while removing the countertops and backsplash which really helped to keep the dust level down. Lisa recommended vendors for our granite, tile backsplash and sink - they were all so helpful. We have never done a kitchen renovation before and were a little anxious about the process and making choices. Lenny allayed our fears and was spot on with suggestions. Lisa was always available for communication and answering questions. The sub-contractors were all excellent, personable and professional. The whole job was finished ahead of schedule which allowed for our 18 month old granddaughter to come for an earlier visit! Overall we are thrilled with the outcome and will definitely use Apple Wood for future projects!"

FAQs for radon gas testing projects in Merrimack, NH

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.
