"Matt did an excellent job. He came to my house, assessed the basement, offered to arrange for a dumpster, and removed the damaged items left by the previous occupants. He provided two quotes, one including the dumpster fee and one without. A week later, he returned and worked quickly and efficiently. He was polite, professional, and hardworking throughout the process. Thanks to his efforts, my basement no longer has a moldy smell, and there’s no sign of mold, which was our biggest concern with winter approaching. I highly recommend his services."

"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

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."
