Massachusetts insulation and air sealing rebate checklist
Drafty rooms, cold floors, ice dams, and high heating bills can point to insulation or air sealing opportunities. In Massachusetts, the first step is usually understanding how a home energy assessment and program rules apply to your home.
Important: Get Rebate Ready is informational only. We are not Mass Save, a utility, a government agency, or a contractor. Verify all requirements before authorizing work.
1. Start with the home energy assessment question
Mass Save describes insulation and air sealing offers tied to residential efficiency programs, and income-eligible residents may qualify for additional no-cost upgrades. Ask whether you need an assessment before work starts.
2. Identify the problem areas
- Attic insulation depth and air leaks
- Basement or rim joist sealing
- Exterior wall insulation gaps
- Drafty rooms, uneven temperatures, or high energy bills
- Moisture, ventilation, knob-and-tube, or safety issues that could affect eligibility
3. Ask contractors these rebate-readiness questions
- Are you approved for the relevant Mass Save insulation or air sealing work?
- What incentives apply before vs. after income verification?
- What work must be completed before heat pump rebates or financing?
- Will I receive documentation showing scope, materials, and program compliance?
- What parts of the quote are not covered by incentives?
