Double-hung windows in Spokane, Washington
Two vertically sliding sashes; both the top and bottom sash open. For Spokane's older housing stock (68.6% 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 Spokane typically cost $700–$3,195 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 Spokane 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 Spokane's climate
Spokane sits in the ENERGY STAR Northern zone (IECC zone 5B (cold, dry), Spokane 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 Spokane
Double-hung window replacement in Spokane runs $700–$3,195 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. Spokane quotes are shaped less by labor rates than by product and prep. The dominant driver is glass: because the state energy code and the cold-dry climate push toward low U-factor units, many honest local bids assume triple-pane or high-end double-pane, which sits above the basic double-pane that national averages often reflect. The second driver is the age of the stock — homes from around the 1961 median frequently have out-of-square openings, old aluminum frames, or prior remodel work that turns a simple insert into a full-frame replacement. Where quotes vary most is on which of these a contractor assumes, so it is worth confirming pane count, the NFRC U-factor, and whether the bid is an insert or full-frame before comparing numbers. One offset worth pricing in: Avista's residential window rebate pays more for lower U-factor glass, which narrows the gap between a code-minimum window and a better-performing one.

Rebates & incentives in Washington
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.
Washington runs IRA Home Energy Rebate programs; whole-home efficiency retrofits can include windows. Confirm current status and funding availability before promising rebate money. See our Spokane guide for the full program list.
