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."

Insulation questions, answered by experts

Periodic checks for moisture or pest issues ensure consistent performance.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

You don’t need to remove old insulation before adding new insulation. As long as the old insulation is still in good shape—not wet, physically damaged, or moldy—then you can stack new insulation on top of old insulation to get a compounding effect. You can also mix different types of insulation, like adding blown-in insulation around existing fiberglass batt insulation or installing rigid insulation boards over rafters in your attic that already have batt insulation installed. If your existing insulation is very old or damaged, though, you’ll likely see more benefit from removing it and replacing it instead.
