New Leaf Construction is the best small contractor that helps home owners take care of their homes. We are a company built on the core values of Integrity, Service, and Excellence, with a focus on quality and open honesty. Our work comes with a guarantee and we stand behind it every day. All of our services are provided under the umbrella of a full insurance policy (available in writing to any client upon request) and we are pleased to offer free estimating as well. We feel the rapidly-increasing number of families who depend on New Leaf Construction to take care of their needs speaks to the calibre of our company and the characteristics of our work.

"Our experience with New Leaf Construction in December led us back to hiring them again for a few additional projects we wanted completed outside this spring. The remodel of our firm over the winter was very successful and it was a pleasure to work with their crew. Their professionalism showed throughout the entirety of the project, from the quality of their work, sensitivity to our timeline, accommodating the needs of our business with as little interruption as possible, cleanliness of their work area, attention to detail, and staying on budget. I highly recommend New Leaf Construction."

Home Snuggers specializes in improving home insulation in Maine and features RetroFoam, the best choice for insulating an existing home. Every home is unique so our estimators determine the best insulation for each and every customer individually. Each area of your home may require a different type of insulation which may be a blown in insulation, spray in insulation, foam insulation, cellulose, or other type of home insulation foam. How do we help you save money? We help you identify the type of insulation that will pay for itself the fastest. RetroFoam, one of our most popular products, works well for homes with poor wall insulation or walls with no insulation at all. RetroFoam is an eco-friendly, nonflammable foam that quickly acts to seal gaps and cracks, keeping precious heat inside on cold days and cool air in summer months. Installation is done from outside so it’s quick, clean, and hassle free. Did you know that, for Maine, foam insulation surpasses fiberglass or cellulose? It also reduces outside noise, stops drafts, and is guaranteed never to settle. Home Snuggers installers are trained professionals who can work on any home and answer all your questions about Maine foam insulation. Our customers will tell you how comfortable, effective, and affordable it can be. Insulation is much more affordable than the rising cost of heating of a poorly insulated house over time. Don’t let a leaky house put a drain on your wallet. Contact Home Snuggers today to arrange for a free estimate.

We have been in the building trade for 25 years and added specialty weatherization 6 years ago. We are certified contractors for Maine State Housing Authority and Efficiency Maine. We are EPA Certified Lead Safe Renovators and fully insured. BPI Certified.

"Horrible Job! This outfit changed their appointment times at least five times before actually starting the job. They blew cellulose insulation into our east bedroom attic, but had complete disregard for the mess they created. They ran the discharge hose up through an open ceiling hatch with no attempt at sealing the opening. As a result, cellulose debris & dust was EVERYWHERE! It took my wife and me several hours of vacuuming, washing items, shaking out blankets and rugs, and serious dusting to get the spaces back somewhat civilized."

New England Spray Foam is a registered Efficiency Maine Partner that services the entire state of Maine.

"It took two weeks and many calls & emails for Mark to respond to the problem of a leak in the system which caused damage to the ceilings & floor. When he called back we were told that his company didn't have the time to come out. He referred us to another company that does work for him. Two weeks later, someone came to look at the system, said they think they found the problem and told us if it leaked again to call back because we might need a new pump. Well, it leaked. We called. They didn't return the call. So, we called a local guy who was willing to come out that day. When my husband explained what we were told, he said there was no pump involved. And, he was right because with the information we got from the local guy, my husband was able to fix the problem in ten minutes. Very disappointed in the lack of and quality of service from New England Spray Foam."

Energy Efficiency Auditing questions, answered by experts

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Yes, including optimizing settings and suggesting upgrades if needed.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.
