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."

Radon gas testings FAQs
Radon gas is a serious health hazard, as it is the second leading cause of lung cancer in the United States. When inhaled, radon breaks down into radioactive particles that can damage lung tissue. Because radon is odorless and invisible, regular testing every two years is crucial to detect its presence. If you have recently remodeled or started using different areas of your home, like the basement, additional testing is essential to ensure your family's safety.
Yes, you need a radon test to ensure your home is safe. The EPA recommends testing your home for radon every two years and after any renovations. Since about one in every 15 homes has elevated radon levels, regular testing is essential. Including a radon test in your home inspection is crucial when buying or selling a property, and some areas require disclosure of radon levels by law. Don't rely on neighboring homes or regional data; the only way to know your home's radon levels is through testing.
Certified professionals conduct radon testing, including accredited home inspectors and specialized radon mitigation companies. These experts follow strict EPA guidelines and use calibrated instruments to accurately measure radon levels throughout your home. Choosing a certified provider ensures you receive reliable results that protect your family's health and property.Professional testing is crucial for accurate detection and effective mitigation if needed.
Radon inspectors typically specialize in testing and assessing radon levels but may not perform mitigation services themselves. If your radon inspector identifies elevated levels of radon in your home, they will recommend a qualified radon mitigation specialist to address the issue. These mitigation experts install systems designed to reduce radon concentrations effectively, ensuring your home is safe.
No, air purifiers are not effective in removing radon gas from your home. Air purifiers are designed to filter out particles like dust and pollen, but radon is a radioactive gas that cannot be captured by standard air filters. To reduce radon levels, you need a specialized radon mitigation system that removes the gas from your home, ensuring your indoor air remains safe.
While opening windows may temporarily reduce radon levels by allowing some gas to escape, it is not an effective long-term solution. Radon continuously enters your home from the soil, and relying on open windows is not practical or sufficient to reduce levels significantly. To effectively lower radon concentrations, you need a professional radon mitigation system that actively removes the gas, ensuring consistent and safe indoor air quality.
