Double-hung windows in Davenport, Iowa
Two vertically sliding sashes; both the top and bottom sash open. For Davenport's older housing stock (70.2% 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 Davenport typically cost $625–$2,840 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 Davenport 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 Davenport's climate
Davenport sits in the ENERGY STAR Northern zone (IECC zone 5A (cool, moist), Scott 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 Davenport
Double-hung window replacement in Davenport runs $625–$2,840 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. Davenport quotes follow the same drivers as anywhere — the number of openings, frame material, glass package, and whether the crew does a simple insert or a full-frame tear-out — but the age of the stock is the local wildcard. With a 1966 median and better than seven in ten homes built before 1980, out-of-square openings, tired wood or early aluminum frames, plaster returns, and prior remodel work are common, and any of them can turn a straightforward insert into a full-frame replacement. Floodplain homes add another consideration: bringing an old below-grade basement window up to egress code can mean a larger opening and an exterior window well, which adds cost but adds real safety and resale value. Because Iowa's rebate landscape is thin right now, plan the budget assuming you pay full price. Rather than trust a headline per-window figure, get itemized written quotes from multiple local installers and compare the same glass spec, pane count, and installation method line for line.

Rebates & incentives in Iowa
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.
Iowa's Home Energy Rebates are administered by the Iowa Economic Development Authority alongside the Iowa Finance Authority, with roughly $120 million split across the HOMES and HEAR tracks. As of mid-2026 neither program had launched to the public — the state had applied for funds but the rollout stalled amid federal DOE funding uncertainty, and no firm start date had been set. Windows would qualify only through the whole-home HOMES modeled-savings track rather than as a standalone rebate; confirm current status before counting on it. See our Davenport guide for the full program list.
