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."

"Tim was excellent to work with. He was quick to respond and quote. Tim handled all the details, coordinating with the Plumbers, Designers, and Permits. While installing the Septic system, he was also hired to do some grading of the property and install a foundation for a large addition. His quotes were fair, he stayed on budget, and his subcontractors were excellent. Most importantly he answered all of my concerns and questions throughout the job. I will definitely recommend his company. "

"Derrik removed a fair amount of sand box sand that i was having a hard time disposing of, then dug out 5 cement footing to our old playground and finally leveled and landscaped a section of our back yard. I couldn't be more pleased with his work. He even discounted his original estimate because we did not need top soil and I and my neighbor assisted ( if you want to call it that) some of the raking. I highly recommend Derrick and Northen Edge phil and beth"
