Insulation & Air Sealing
Making air sealing and insulation upgrades are two of the most cost-effective ways to boost efficiency and save money.
Insulation and air sealing work hand in hand to save energy, money, and increase your comfort at home. Air sealing is usually the first step—eliminating leakage points in your home, like attics, basements, and between joists.
Benefits of insulation and air sealing improvements include:
- Lowering heating and cooling costs by up to 15 percent
- Decreasing drafts to improve comfort and humidity all year long
- Minimizing outside noise for a quieter, more peaceful environment
- Reducing the chance of ice dams—protecting your home from potential damage
The Sponsors of Mass Save also offer no-cost insulation and air sealing upgrades to income-eligible residents.
Schedule a no-cost Home Energy Assessment with trusted lead vendor, {{HLA}}. Call 866-527-SAVE or schedule online.
You can also choose a participating Home Performance Contractor to complete your no-cost Home Energy Assessment. The same contractor can also complete any recommended insulation and air sealing work during a follow-up visit.
If you already know what upgrades you’re looking to make and you are looking to access quick incentives, you may access direct incentives for insulation and/or air sealing upgrades. You can skip the assessment and work with a Direct Weatherization Independent Installation Contractor to scope out your project and access incentives.
For heat pump installations, you can contact a Heat Pump Installer Network Contractor to receive a quote.
Your municipal utility is not part of the Mass Save program. Please contact them directly for energy efficiency program information.
