Double-hung windows in Boston, Massachusetts
Two vertically sliding sashes; both the top and bottom sash open. For Boston's older housing stock (73.6% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR Northern zone, the number that matters most is a low U-factor (≤ 0.22) to keep heat in.
Short answer
Double-hung windows in Boston typically cost $760–$3,450 installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Double-hung window right for a Boston home?
Both sashes slide vertically and typically tilt inward for cleaning.
Where it fits:
- Traditional and historic home styles
- Rooms facing walkways, porches, or patios (no outward projection)
- Easy cleaning from inside on upper floors
What to weigh:
- More potential air-leakage paths than hinged styles at equal quality
- Half the opening ventilates at any one time
Double-hung windows and Boston's climate
Boston sits in the ENERGY STAR Northern zone (IECC zone 5A (cool, moist), Suffolk County), where the priority is a low U-factor (≤ 0.22) to keep heat in.
Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the Northern zone, prioritize a well-built unit and a low U-factor (≤ 0.22) to offset that.

What Double-hung windows cost in Boston
Double-hung window replacement in Boston runs $760–$3,450 installed. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand. Boston sits at the expensive end of the national range, and the drivers are structural rather than mysterious. Labor costs in Greater Boston run well above national averages, and the housing stock — median build year 1947 — means installers routinely encounter out-of-square openings, weight-and-pulley pockets that need insulating, rot in sills and frames, and lead-safe work practices required on pre-1978 homes. Full-frame replacement is often the honest recommendation over a cheaper insert, and historic district projects that require true divided lites or wood sashes can cost a multiple of a standard vinyl job. Two things push the other way: Mass Save's no-cost home energy assessment gives you a free, independent read on whether windows are actually your biggest problem before you spend, and its 0% HEAT Loan can finance qualifying work. Get itemized bids that separate the unit, the labor, and any frame or trim repair.

Rebates & incentives in Massachusetts
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
Massachusetts' Department of Energy Resources (DOER) is delivering IRA Home Energy Rebates through the existing Mass Save infrastructure rather than as a separate application, with funds prioritized for income-eligible households. As of mid-2026 the rebates had not fully launched for general homeowner applications. Confirm current status through Mass Save. See our Boston guide for the full program list.
