Double-hung windows in Westchester, New York
Two vertically sliding sashes; both the top and bottom sash open. For Westchester's older housing stock (82.1% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR North-Central zone, the number that matters most is a low U-factor (≤ 0.25) to keep heat in.
Short answer
Double-hung windows in Westchester typically cost $790–$3,585 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 Westchester 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 Westchester's climate
Westchester sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Westchester County), where the priority is a low U-factor (≤ 0.25) 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 North-Central zone, prioritize a well-built unit and a low U-factor (≤ 0.25) to offset that.

What Double-hung windows cost in Westchester
Double-hung window replacement in Westchester runs $790–$3,585 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. Westchester runs expensive, and the drivers are structural rather than seasonal. The prevalence of pre-1980 homes — many with original wood frames that are out of square, settled, or rot-damaged at the sill — pushes installers toward full-frame replacement over a cheaper pocket (insert) install on a meaningful share of jobs, which raises the per-window price but addresses the surrounding wood. On top of that, the market's preference for wood and clad-wood units to match Tudor, Colonial, and Victorian architecture costs more than the vinyl that dominates newer metros, and downstate New York labor rates sit above national averages. Where a village architectural review applies, matching an approved profile or material can further limit the cheapest options. National cost ranges (such as NREL and industry survey data) are a starting point, but Westchester quotes tend to land at the higher end for these reasons. Get itemized bids that separate the window unit from labor and from any frame, sill, or trim repair, and be cautious of a single low number that hides scope.

Rebates & incentives in New York
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.
New York runs IRA Home Energy Rebate programs through NYSERDA; whole-home efficiency retrofits can include windows within a modeled-savings project. Confirm current availability first. See our Westchester guide for the full program list.
