Benefits of Mass Save Air Sealing for Your Home
Air sealing your home has many benefits. One of the best? With Neeeco and the Mass Save program, you can qualify for no-cost air sealing plus insulation rebates worth up to 100% off the cost of an insulation installation. Insulation and air sealing work best together, so take advantage of both these rebates from Mass Save and enjoy benefits like:
What Is Air Sealing?
Most homes are not airtight—they’re full of small gaps and cracks that let air move into and out of the home. This is called air leakage and it leads to a lot of energy waste. Wasted energy means wasted money, so it’s important to seal those leaks up!
Air sealing involves plugging the cracks where air is leaking from the home. Depending on the size and location of the leak, different materials are used for this purpose. We typically use caulking and weatherstripping to create a tight seal around windows, doors, and pipes, where air leaks are often located.
Air sealing is best handled by a professional air sealing contractor, like Neeeco. With a no-cost Mass Save energy audit, we can pinpoint the exact location of air leaks in your home and help you qualify for air sealing rebates! Schedule a no-cost Mass Save energy assessment to see if you’re eligible for no-cost air sealing.
Where Are the Air Leaks in Your House?
Air leaks can be located almost anywhere in a home, though some areas are more prone to leakage than others. Air leakage is a byproduct of home construction. During the assembly process, thousands of materials are joined together, and there is almost always a small gap between the place where two materials meet. By the time construction is complete, there are leakage points all over.
Up to 40% of Energy Loss in a Home Is Due to Air Leakage
In an average home, 25-40% of the energy used for heating and cooling is lost due to air leakage. This means you’re likely spending a lot more than you need to on energy costs.
Basements Air Leaks
Most basements have multiple air leak locations. Cracks in the foundation, gaps where floor joists are bolted together, and holes drilled to accommodate water lines, plumbing, electrical, and dryer vents all contribute to air leakage in a basement. These holes suck external air in and let heated or cooled air leak outside.
Attic Air Leaks
Sealing the attic is an important first course of action against air leakage. This is because rising heat forms a convection current that draws air up into the attic and then out through whatever openings exist. This creates a phenomenon called the stack effect, which draws air from below, creating a negative pressure that sucks in outside air through basement air leaks.
By sealing the attic, air is not allowed to escape, which then stops the upward airflow from transferring energy out of the house. Air sealing your attic will help you save energy year-round.
How Much Does Air Sealing Cost?
Air sealing is one of the most cost-effective ways to stop energy loss in a home. Thanks to Neeeco and the Sponsors of the Mass Save Program, air sealing is available at no cost to Massachusetts homeowners. Have questions about Mass Save rebates? Visit our Mass Save FAQs page.
