Veteran owned and operated with over a decade of experience in the demolition and environmental services.
"The 1964 bulkhead I had out back was replaced a year ago, but the wood and insulation underneath (the ceiling of the walkway underground to my basement under the back living room) took in water damage and the area was very musty for years. Tom Morneault of Morneault Environmental was the only guy I could find that would not only treat the wood to remove anything growing on it/get rid of the smell, but his team also removed old wood and insulation and re-insulated for me as part of the deal, which was still hundreds of dollars cheaper than the other companies I talked to, which would only remove the old wood and insulation, they don't put anything back in. Tom's team was here by 8:30 this morning and by 2pm they were done and it looks fantastic and smells crisp and clean. They didn't even stop for breaks or have to make any trips to get supplies, they had them all in the van, including the insulation boards. Very highly recommended if anyone is in the same situation."

Providing excellent customer service and a quality end product. We continually strive to maintain a synergy of excellence and experience that is second to none. Passion for quality drives everything we do.
"Avoid this company at all costs! . Paul Davis came recommended to me by my plumber so I hired them for to do restoration work for water damage my home sustained. For starters, It took them almost 5 months to get me an accurate estimate. They needed to have people come to my home 5x to assess the damage because the right hand does not talk to the left with this company. I was given excuse after excuse as to why they couldn't give me an estimate. Eventually after many months of excuses (family emergency, weather conditions, the flu went around the office etc etc...), they finally provided me with an accurate estimate whereupon I signed an electronic contract for the work to be completed. Two days later I emailed them to say I needed to postpone the work for a few days because I was having unexpected house guests that coming during the holidays. I was told that would be no problem. When I tried to reschedule, I was ignored for a week. I continued to inquire about rescheduling my job and I was told to take me business elsewhere! So I have now invested 6 months of time having person after person come through my home to look at the damage and they will not do the work, even after I signed a contract. There customer service is terrible and they do not value your business. Save yourself precious time and go with any other company. I wish I had"

FAQs for radon gas testing projects in Dover, 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.
