If you're a homeowner in Central Maine, you already know what winter heating bills look like. Between oil, propane, and electric costs, keeping your home warm from November through April can easily run into thousands of dollars. The good news? The single most effective way to reduce those costs isn't a new furnace or heat pump — it's upgrading your home's insulation and sealing the air leaks that let your heated air escape.
At Nason's Home Solutions, we've helped hundreds of homeowners across the Bangor area transform their homes from drafty and expensive to comfortable and efficient. Here's why insulation and air sealing should be at the top of your home improvement list.
The Hidden Problem: Air Leaks
Most homeowners focus on their heating system when they think about energy efficiency. But even the best furnace can't keep up if your home is leaking air. Common trouble spots include attic hatches, recessed lights, plumbing penetrations, electrical outlets on exterior walls, and gaps around windows and doors.
Our air sealing service targets these hidden leaks using professional-grade materials and diagnostic tools. We start with a thorough assessment of your home to identify exactly where air is escaping, then seal every gap systematically. The result? Your heating system works less, your home stays warmer, and your bills drop — often by 20-30%.
Insulation: Your Home's Thermal Barrier
Even with air leaks sealed, inadequate insulation means heat transfers right through your walls, attic floor, and basement ceiling. Many older Maine homes were built with minimal insulation by today's standards, and what's there may have settled, compressed, or deteriorated over the decades.
Our insulation services include spray foam, blown-in cellulose, and fiberglass options depending on your home's needs and budget. Spray foam is particularly effective because it insulates and air seals simultaneously, creating a continuous thermal barrier that dramatically reduces heat loss.
Don't Forget Your Basement and Crawlspace
Your basement and crawlspace are often the biggest sources of energy loss and moisture problems in a Maine home. An uninsulated basement can account for up to 30% of a home's total heat loss. Cold floors, damp air, and musty odors are all signs that your below-grade spaces need attention.
Crawlspace encapsulation seals your crawlspace from ground moisture and outside air, creating a clean, dry, conditioned space that improves your home's comfort and air quality. For basements, our waterproofing solutions address water intrusion at its source, protecting your home's foundation and creating a healthier living environment.
The Mold Connection
Poor insulation and air sealing don't just waste energy — they create the conditions for mold growth. When warm, humid indoor air meets cold surfaces (like an under-insulated exterior wall), condensation forms. Over time, that moisture feeds mold and mildew, which can damage your home's structure and affect your family's health.
If you've noticed musty smells, visible mold, or unexplained allergic symptoms, you may have a moisture problem that's directly related to insulation deficiencies. Our mold removal service is performed by IICRC-certified technicians who not only eliminate existing mold but help identify and correct the underlying moisture issues that caused it.
Efficiency Maine Rebates: Up to $8,000 Back
Here's where the investment gets even smarter. Efficiency Maine offers substantial rebates for insulation and air sealing projects — up to $8,000 for income-eligible homeowners. Even at the standard tier, rebates of $4,000 are available for qualifying upgrades.
An energy audit is the first step to qualifying for these rebates. Our BPI-certified team performs comprehensive energy assessments that identify the most impactful upgrades for your specific home. The audit itself is often subsidized by Efficiency Maine, making it an easy first step toward significant savings.
The Basement Finishing Bonus
Many homeowners who start with insulation and waterproofing end up discovering they have usable space they never considered. Once your basement is dry, insulated, and properly sealed, basement finishing becomes a practical option that adds living space and home value without the cost of an addition.
What to Expect from the Process
Every project starts with a free assessment. We visit your home, evaluate your current insulation and air sealing, identify problem areas, and provide a clear estimate with no hidden fees. If rebates apply, we help you navigate the paperwork so you get every dollar you're entitled to.
Most insulation and air sealing projects can be completed in one to three days depending on the scope of work. We take care to protect your home during the process, clean up thoroughly, and walk you through the completed work so you can see exactly what was done.
Real Results for Maine Homeowners
The homeowners we work with in Bangor, Hampden, Old Town, Orono, Brewer, and across Central Maine consistently report the same things after their projects are completed: warmer floors in winter, more even temperatures throughout the house, lower heating bills, and a home that just feels better.
That's not marketing — it's physics. When you stop losing heat through your walls, attic, and basement, your home holds its temperature the way it was designed to. Your heating system runs less, you use less fuel, and you spend less money. It's that straightforward.
