Massachusetts Insulation Rebates & Mass Save® Weatherization Incentives | Revise, Inc.
Insulating and air sealing your home is one of the smartest energy investments you can make — and in Massachusetts, you don’t have to pay full price to do it. Through the Mass Save® program, eligible homeowners can get up to 75–100% off qualifying insulation upgrades, no-cost air sealing, and 0% financing on top of it all. Here’s everything you need to know.
What Are Mass Save® Insulation Rebates?
Mass Save® insulation rebates are financial incentives that cover up to 75–100% of the cost of qualifying insulation upgrades for Massachusetts homeowners. The Mass Save® program is a collaboration of the state’s electric and gas utilities and is available to all Massachusetts residents. Program delivery happens through certified Mass Save® partners like Revise, Inc.
How Much Can You Save?
Insulation Rebates: Up to 75%–100% Off
All Massachusetts residents qualify for up to 75% off insulation upgrade expenses, capped at $2,000 in recommended improvements. Income-eligible households can qualify for up to 100% off. Rebates are applied directly at project completion — no reimbursement forms, no waiting. Common qualifying upgrades include attic, exterior wall, and basement insulation.
No-Cost Air Sealing
Air sealing is provided at 100% no cost through Mass Save®. It stops conditioned air from escaping through gaps around pipes, outlets, and attic hatches, keeping your home more comfortable while reducing energy waste year-round.
0% HEAT Loan Financing
The Mass Save® HEAT Loan offers 0% interest financing for up to $25,000 over 84 months for qualifying improvements, including insulation, air sealing, heat pumps, heat pump water heaters, and replacement windows. It can be stacked with rebates — so you can reduce your project cost with a rebate and finance any remaining balance interest-free.
What Is a No-Cost Home Energy Assessment — and Why Does It Unlock Your Rebates?
A Home Energy Assessment is the required first step to accessing Mass Save® insulation rebates — and it comes at no cost. Think of it as your key to unlocking everything above.
When you schedule a Mass Save® No-Cost Home Energy Assessment conducted by Revise, Inc., here’s what you receive:
- A customized home energy report identifying where your home is losing energy
- No-cost sealing of air leaks discovered during the visit
- Access up to 75%–100% off recommended insulation improvements (up to $2,000)
- 0% financing on qualifying improvements
- Rebates on high-efficiency heating, cooling, and water heating equipment
The assessment ensures you only invest in upgrades that will genuinely improve your home — and that you don’t leave a single rebate dollar on the table.
Weatherization 101: Insulation + Air Sealing Working Together
Insulation and air sealing aren’t competing upgrades — they’re a team. Insulation slows heat transfer through walls, ceilings, and floors. Air sealing stops air from moving freely through gaps and cracks, regardless of how much insulation is in place. Think of insulation as a winter coat and air sealing as zipping it up.
Together, they deliver benefits well beyond lower energy expenses, including more consistent temperatures room to room, reduced moisture and mold risk, better indoor air quality, and less wear on your HVAC system.
A note on spray foam insulation: Although Mass Save® doesn’t cover spray foam insulation upgrades, it is a great option to consider for improving your home’s energy efficiency. Your Revise, Inc. Home Energy Manager can walk you through all available materials and help identify the right solution for your home.
Are You Income-Eligible for Extra Savings?
Income-eligible Massachusetts households can receive up to 100% off the cost of insulation upgrades — meaning a full upgrade at no out-of-pocket cost. Eligibility is based on household income and size, and it’s broader than many homeowners expect. The easiest way to find out is during your Mass Save® No-Cost Home Energy Assessment conducted by Revise, Inc., where your Revise, Inc. Home Energy Manager will review your eligibility at no charge.
