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

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

There are several indications of an overloaded electrical panel, such as frequent circuit breaker tripping, burn marks, or flickering or dimming lights.

If you’re observing any warning signs, turn the circuit breaker off, then shift some devices from the overloaded circuit to a different one. If there are still signs of overload after turning the circuit break back on, contact a professional electrician to help you fix the issue.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
