Every Maine homeowner qualifies for 80% off insulation and air sealing through Efficiency Maine. Income-eligible households can get up to $8,000. Smooth is a Registered Vendor — we apply the rebate directly to your invoice.
Efficiency Maine is an independent state agency (not a utility program). It rebates energy-efficiency measures for every Maine electricity customer. The program is funded by a system benefits charge on Maine electric and gas bills — you've already been paying in.
For insulation and air sealing:
Efficiency Maine requires an "Energy Upgrade Bundle" (air sealing + basic weatherization measures) before issuing insulation rebates, unless your home was previously weatherized. For most homes, this is the first visit — we scope both the bundle and the insulation in one proposal.
Federal Section 25C tax credits expired December 31, 2025 — no federal credit is available for 2026 insulation work. Efficiency Maine rebates are unaffected and remain the primary Maine incentive.
Not for the base 80% tier — every Maine homeowner qualifies. Income documentation is only needed if you want the higher moderate-income or low-income tier.
No. Efficiency Maine rebates approved insulation materials (cellulose, fiberglass, rigid foam) and air sealing. Spray foam is an out-of-pocket premium measure — we often combine it with rebated work in the same job.
For most projects, no. As a Registered Vendor, we can scope the project directly. An assessment is required if you're pursuing the low-income tier or the HESP/LIHESP bundles.
No. The property must be your primary year-round residence (occupied at least 6 months per year). Vacation homes, seasonal rentals, and second homes are not eligible.
Registered Vendors apply the rebate to your invoice up front — you never wait for a reimbursement check. We also handle all rebate paperwork on your behalf.
Yes — Efficiency Maine partners with several banks on home energy loans. PACE financing is available in participating municipalities. MaineHousing offers income-qualified loans.
