September in Maine: It's Time to Get Ready for the Cold

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.

Maine Attic Nightmares: Condensation, Mold, and Protecting Your Home

By Mattra Inc • August 18, 2025
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. Protecting your Maine home starts from the top down!

Blower Door Test

By Mattra Inc • April 3, 2025
Is Your Home Under-Insulated and Leaky? A Blower Door Test Can Tell You Many Maine homeowners don’t realize just how much money is flying out the window—literally. Drafty rooms, cold floors, and rising energy bills are often signs of poor insulation and hidden air leaks. But how do you know where your home is losing heat? A blower door test is one of the most effective tools to identify under-insulated and under-sealed areas in your home. Let’s explore how it works, why it matters, and what steps you can take to improve your home’s energy efficiency—and unlock valuable Efficiency Maine rebates in the process. What Is a Blower Door Test? A blower door test uses a powerful fan, mounted into an exterior doorway, to pull air out of your home and lower the indoor air pressure. This forces outside air in through any cracks or gaps in the building envelope. The result? A clear picture of where your home is leaking air. This test measures air changes per hour (ACH) and identifies weak points in insulation and air sealing. It helps assess how well your home keeps conditioned air in—and the outdoor elements out. An experienced technician can use this data to recommend targeted upgrades, saving you money on heating and cooling costs. How to Pass a Blower Door Test: Key Air Sealing Tips Passing a blower door test doesn’t require a full renovation—it’s about sealing the right places effectively. Here are the most common areas to focus on: 🪟 Windows and Doors Install weather stripping Use caulk or foam sealant around frames Check for gaps in thresholds or broken seals 🧱 Attics and Ceilings Seal around light fixtures and access hatches Insulate attic floors and rafters Use foam board or spray foam in hard-to-reach corners 🧰 Basements and Crawlspaces Seal rim joists with spray foam Insulate basement walls and floors Cover and seal crawlspace vents and doors 🧹 Floors and Walls Fill gaps around pipes, wiring, and ducts Seal baseboards and floor edges Add insulation in wall cavities if accessible By addressing these common problem areas, you can drastically improve your blower door test results and the overall comfort of your home. Why Blower Door Testing Matters Blower door tests aren’t just for code compliance—they’re a diagnostic tool to understand your home's efficiency. When performed by professionals, these tests: Reveal hidden air leaks Provide data for insulation and air sealing improvements Help reduce energy bills Improve indoor comfort and air quality Support home energy audit documentation During the test, technicians record the building's air leakage rate using calibrated gauges. Smoke pencils or infrared cameras may also be used to visualize the leaks. This ensures your energy upgrade dollars go exactly where they’re needed most.
