Program Overview

Efficiency Maine Insulation Rebate Program

The Efficiency Maine Home Rebate Program helps Maine homeowners offset the cost of home insulation improvements. Through the Home Energy Savings Program (HESP), homeowners at any income level can receive rebates that cover a significant percentage of their insulation project.

The program works through a network of Registered Vendors like Mattra. We perform an energy assessment, identify where your home is losing heat, and recommend the scope of work that qualifies for the highest rebate. After the installation, we submit the documentation and you receive the rebate.

For most Maine homes, insulation and air sealing are the two upgrades with the fastest return on investment. The rebate reduces the upfront cost. The energy savings reduce your heating bills every year after that.

Any-Income Rebates Available

Every Maine homeowner qualifies for at least the 40% rebate tier. No income verification required. Income-eligible households can access 60% or 80% tiers for even greater savings.

Eligibility

Who Qualifies for Efficiency Maine Insulation Rebates?

The rebate program is available to most Maine homeowners. Below are the requirements and exclusions.

You Qualify If:

  • Your home is owner-occupied
  • Your home is located in Maine
  • The home is your primary, year-round residence
  • Your home is heated by a thermostat-controlled system (oil, propane, natural gas, electric, kerosene, or wood pellets)

Does Not Qualify:

  • Rental properties (tenant-occupied)
  • Seasonal or vacation homes
  • New construction
  • Homes heated solely by cord wood
  • Commercial or business-use properties

Entry Point: Energy Upgrade Bundle

Before insulation rebates apply, the program requires an Energy Upgrade Bundle (energy assessment plus basic air sealing). The exception is homes that have been previously weatherized through Efficiency Maine or a Community Action Agency. Mattra walks you through which step applies to your situation.

Any-Income Tier

Maine Insulation Rebates at Every Income Level

You do not need to be low-income to benefit from the Efficiency Maine rebate program. The any-income tier is available to every qualifying homeowner in Maine, with no income verification required.

What the Any-Income Tier Covers

  • Air Sealing — up to $500 as part of the Energy Upgrade Bundle. Sealing air leaks around framing, plumbing, and electrical penetrations is the foundation of any insulation project.
  • Insulation — up to $4,000 (40% of project cost). Covers attic, wall, and basement insulation upgrades including blown-in insulation, spray foam, and dense-pack cellulose.

Combined potential: up to $4,500 in rebates for any-income households. Moderate- and low-income households receive higher percentages, and the insulation rebate cap increases accordingly.

Lifetime Limits Per Area

The program allows one rebate per area per property: one attic insulation rebate, one wall insulation rebate, and one basement insulation rebate. If you have multiple areas that need upgrading, each qualifies separately.

Covered Upgrades

Insulation Upgrades That Qualify for Maine Rebates

The Efficiency Maine program covers multiple types of insulation work. Each addresses a different part of your home's thermal envelope.

Air Sealing

The required starting point. Sealing air leaks around plumbing, wiring, ductwork, and framing penetrations stops the heat loss that insulation alone cannot address. Included in the Energy Upgrade Bundle.

Learn About Air Sealing

Attic Insulation

The largest single source of heat loss in most Maine homes. Blown-in cellulose or fiberglass brings attic R-values up to current standards, reducing heating costs and preventing ice dams.

Learn About Attic Insulation

Wall Insulation

Older Maine homes often have minimal or compressed wall insulation. Dense-pack cellulose and blown-in insulation methods upgrade thermal performance for residential insulation contractors projects without major renovation.

Learn About Wall Insulation

Basement Insulation

Cold basement walls and rim joists let heat escape from the entire house above. Spray foam and rigid board insulation seal the basement envelope and improve comfort on every floor.
