Mass Save pays $75 per window in 2026, and only when ENERGY STAR Most Efficient windows replace single-pane windows after you complete the weatherization recommendations from a Home Energy Assessment.

Replacing double-pane windows earns no rebate. The 0% HEAT Loan can finance ENERGY STAR replacement windows, but only alongside completed weatherization recommendations.

Do you need a permit for replacement windows or doors in Nantucket?

Plan on one. Window and door replacement is not on the Massachusetts building code's list of permit-exempt work, and the Nantucket Building Department decides whether a same-size swap counts as an ordinary repair. 43% of Nantucket's homes were built before 1980 (Census ACS 2018-2022), and work that disturbs paint in a home built before 1978 has to follow the lead-safe renovation rules.
