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."

Energy Efficiency Auditing questions, answered by experts

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.
