How Income Tiers Affect Your Rebate
Any Income
Every Maine homeowner who installs qualifying insulation through a certified contractor is eligible for 40% of their project cost back, up to $4,000. No income verification required. This is the baseline rebate that applies to all qualifying projects.
Moderate Income
Homeowners who meet the Efficiency Maine moderate income threshold qualify for 60% back on their project cost, up to $6,000. Income verification is required. Contact Efficiency Maine directly or ask us during your assessment — we can help determine whether you are likely to qualify.
Low Income
Homeowners who participate in HEAP (Home Energy Assistance Program) or SNAP (Supplemental Nutrition Assistance Program) qualify for 80% of project costs back, up to $8,000. This is the most generous tier and can cover the large majority of a full home insulation project for eligible households.

Rebate Calculator: Frequently Asked Questions
The calculator uses typical Maine installation cost ranges to estimate your project cost, then applies the Efficiency Maine rebate percentage for your income tier. It is designed for budgeting and planning — not for exact quotes. Your actual rebate will be based on your verified project cost, measured R-value improvement, and Efficiency Maine approval. We will give you exact numbers after your free in-home assessment.

Yes. We prepare all required Efficiency Maine documentation as part of every project — R-value completion certificates, pre and post measurements, project photos, and the rebate claim form. You do not need to navigate the process on your own. We have done it hundreds of times.
Efficiency Maine insulation rebates are funded on an ongoing basis, but program funding is subject to availability and can change.
