Efficiency Maine Rebates

Home insulation is a highly important aspect of home ownership, and it's one that many people don't think about until they're already in the thick of it. If you're thinking about insulating your home to keep you warm in the winter, then we've got some good news for you: efficiency Maine rebates are here to help!

What is Efficiency Maine?

Efficiency Maine is a program that helps homeowners improve the energy efficiency of their homes. The program offers rebates on insulation, air sealing, and heating systems.

What is a Efficiency Maine Rebate?

Efficiency Maine is a statewide energy efficiency program that helps homeowners and businesses reduce their energy costs by making their homes and buildings more efficient. They offer rebates to help with the cost of installing new, high-efficiency equipment in your home or business.

Why is home insulation so important?

Insulation keeps your home comfortable and safe by reducing heat loss through the walls, ceiling, and floors. It also helps to keep moisture from getting into your home through those same areas. A leaky home can lead to mold growth and other problems that can be dangerous for you and your family.

What types of things are covered by an Efficiency Maine rebate?

A variety of things are covered by an Efficiency Maine rebate: installation of new windows; installation of new doors; installation of new siding; installation of insulation in attics or walls; installation of air sealing between floors; and much more.

Who can participate in the Efficiency Maine program?

Anyone who owns a home can apply for efficiency Maine grants. The property must also be your primary residence or place of business. You can be a homeowner of any income to qualify. The building or home must be:

  • A single-family home, or
  • A Townhouse, or or
  • A 1- to 4-unit residential building located in Maine. Larger buildings, including 5 or more attached condominiums, are not eligible.
  • Space heated the entire heating season
  • Upgrade cannot be part of a new home construction project or an addition.
  • Lifetime Limits:
  • One $500 air sealing rebate per building or townhouse
  • $4,000 in insulation rebates per building or townhouse


What projects can I get Efficiency Maine rebates for?

There are a variety of projects that increase energy efficiency:

Air Sealing - Efficiency Maine Rebate

Air sealing is a process that improves the energy efficiency of a home.


It involves installing weatherstripping around doors and windows and using caulk to seal cracks in the walls and ceiling, which reduces unwanted air infiltration into the house.


The result of air sealing is more comfortable and efficient living spaces, which means you don't have to turn up the thermostat as much on a cold day or crank up your air conditioning system as high on a hot summer night. This can save you money over time by reducing your heating and cooling bills.

Basement Insulation - Efficiency Maine Rebate

Basement insulation is a great way to gain efficiency in your home. By insulating the basement, you can prevent heat from escaping through your foundation and keep it in your home. This will save you money on heating costs as well as help you feel more comfortable.


Basement insulation is easy to install and can be done by anyone with basic knowledge of how to use tools. If you are interested in installing basement insulation in your home,

Wall Insulation - Efficiency Maine Rebate

Wall insulation is a great way to make your home more efficient. It helps with temperature control and can save you money on your energy bill.


Wall insulation works by creating an airtight seal between the inside and outside of your house. This keeps warm air from escaping during the winter, and keeps cool air from escaping during the summer. Because it's an airtight seal, it also helps keep moisture out of your home.


This helps reduce heating bills in the winter, because less heat is needed to keep the house at a comfortable temperature—saving you even more money!

Attic Insulation - Efficiency Maine Rebate

Attic insulation is one of the most important parts of a home's energy efficiency. A home with good attic insulation will stay cooler in the summer and warmer in the winter, saving you money on your utility bills.


Attic insulation is a material that helps keep heat from escaping through your roof and walls. There are two main types: blown-in fiberglass and batts (also known as rolls).


Blown-in fiberglass is lightweight and easy to install, making it ideal for DIYers. It's also fairly cost-effective. Batts are more expensive upfront, but they're more durable than blown-in fiberglass and require less maintenance over time. 


Both types are effective at keeping heat inside your house during the winter months and outside during the summer months!

September in Maine: It's Time to Get Ready for the Cold The air is getting crisp, the days are getting shorter, and that first real chill of September is a reminder that winter is right around the corner. If you're anything like us, you're not exactly looking forward to those high heating bills. You’re probably picturing a drafty living room, cold floors, and that thermostat you keep nudging higher and higher just to feel comfortable. But what if you didn't have to? This isn't about just surviving another Maine winter; it’s about thriving. It’s about being truly comfortable in your own home, without the constant stress of watching your energy costs climb. The secret? Proper insulation and air sealing. Investing in your home's insulation now is the smartest thing you can do. It’s like putting money in the bank. You spend a little up front to save a lot later. We’ve seen it time and again—homeowners can slash their energy consumption by as much as half. Imagine what you could do with that extra cash every month. Our Solutions for a Warmer, Cozier Home At Mattra, we know what a Maine winter demands. That’s why we offer solutions that actually work. Closed Cell Spray Foam - This is our top-tier solution, and it’s a game-changer for a home’s efficiency. When applied, this foam expands into a dense, rigid material that creates an incredible air and moisture barrier. We use it to seal crawl spaces, basements, and exterior walls. Think about that cold basement feeling—spray foam completely eliminates it. By sealing those critical areas, you prevent a tremendous amount of heat loss and stop cold, damp air from entering your living space. This is more than just insulation; it's a complete building envelope upgrade that also adds structural integrity and helps prevent moisture issues and mold growth. It's the ultimate defense against the Maine elements. Blown-In Cellulose - Made from recycled paper products, blown-in cellulose is one of the most eco-friendly insulation options available. We use a powerful hose to blow the material into attics and enclosed wall cavities. The tiny paper fibers pack together to form a seamless blanket of insulation, leaving no gaps for air to escape. It's especially effective in attics, where heat naturally rises and escapes. A properly insulated attic can be the single biggest factor in lowering your heating costs. Beyond its thermal performance, cellulose also has excellent sound-dampening qualities, making your home quieter and more peaceful by blocking out exterior noise. Dense Packing Walls - For older homes that were built without any wall insulation—a common issue in Maine—dense packing is a perfect solution. Instead of tearing down all your interior walls, we can drill small holes and inject cellulose or other materials directly into the wall cavities. This fills every empty space behind your drywall or plaster. The material is packed in so tightly that it significantly reduces drafts and heat loss. It's a non-invasive way to bring an old home's energy performance up to modern standards, drastically improving comfort and saving you money without the mess and high cost of a full renovation. Targeted Air Sealing - Insulation is only half the battle. You could have the best insulation in the world, but if air is leaking in and out of your home, you're still wasting energy. We specialize in using foam to meticulously air seal the two biggest culprits for drafts: your basement and your attic. We target the penetrations where pipes, wires, and framing meet, which are often the main pathways for air leakage. By sealing these critical areas, we prevent the "stack effect," where warm air rises and escapes from the top of your house, pulling cold air in from the bottom. Sealing these areas with foam is a fundamental step that makes all other insulation work more effectively, ensuring your home holds onto the heat you’re paying for. This Is Where It Gets Even Better: Rebates! As a licensed vendor with Efficiency Maine , we can help you access substantial rebates for your weatherization project. This isn't just a small discount—we're talking about real money that makes a huge difference. You are entitled to at least $4,000 in rebates for your project, with the potential for even more depending on your income. We will personally guide you through the process, ensuring you receive every dollar you're entitled to from these incredible programs. This makes an already smart financial decision an absolute no-brainer. Don't wait for winter to sneak up on you. Let's make this year different. Reach out to us at Mattra today for a free consultation. We’d love to help you make your home the comfortable, energy-efficient sanctuary it should be.

That musty smell. The faint water stains on your attic ceiling. Maybe you’ve even spotted some unwelcome dark spots. If you’re a Maine homeowner, especially in our older homes, these could be signs of a serious problem brewing in your attic: condensation leading to mold growth. It's a more common issue than you might think, and it can have significant consequences for your home’s health and your wallet. Why is your Maine attic suddenly feeling like a rainforest? The culprit is often a perfect storm of factors we see frequently here at Mattra: a lack of proper air sealing and insufficient insulation. Think of your warm, humid indoor air rising into the colder attic space. Without proper air barriers, this warm, moisture-laden air sneaks through cracks and openings around wiring, plumbing, and light fixtures. Once this warm, moist air hits the cold surfaces in your uninsulated attic – like the roof sheathing – it cools rapidly. Just like water beading on a cold glass on a summer day, this cooling air releases its excess moisture in the form of condensation. And in a Maine winter, those surfaces stay cold for a long time! Several other common issues exacerbate this problem. That uninsulated attic hatch? It’s a direct pathway for warm, humid air to escape. An uninsulated chimney acts as another cold surface where condensation can form. And those bathroom and dryer vents that aren’t properly ducted to the outside? They’re pumping even more moisture directly into your attic – a recipe for disaster. So, what happens when all this condensation builds up? That’s where mold enters the picture. Mold spores are everywhere, both indoors and out. They thrive in damp, dark environments with organic materials to feed on – like the wood in your attic. Consistent condensation provides the perfect breeding ground. As mold grows, it doesn't just create unsightly stains and that telltale musty odor. It actively deteriorates the materials it grows on. Over time, mold can weaken the structural integrity of your roof sheathing and rafters, leading to costly repairs. It can also damage any stored items in your attic. Beyond the structural damage, mold growth can also impact your indoor air quality. Mold spores can become airborne and circulate throughout your home, potentially triggering allergic reactions, asthma symptoms, and other respiratory issues for you and your family. As a licensed vendor with Efficiency Maine , we understand the importance of a healthy home environment. The good news? These attic issues are often fixable! Proper air sealing prevents that warm, humid air from entering the attic in the first place. Adequate insulation helps maintain a more consistent temperature in the attic, reducing those cold surfaces where condensation forms. Insulating the attic hatch and chimney are crucial details often overlooked. And ensuring your bathroom and dryer vents are correctly ducted to the exterior is essential for removing excess moisture from your home. Addressing attic condensation and mold growth is an investment in your home's long-term health and your family's well-being. If you suspect you have an issue in your Maine attic, don't wait for the problem to worsen. Contact the experts at Mattra right here in Lewiston. We can assess your attic, identify the sources of condensation, and recommend the best solutions for mold remediation and preventing future problems through proper air sealing and insulation.
