The short answer for Des Moines homes

Angi's October 2026 data, drawn from 17,857 projects, puts the national average window project at $7,348, with most between $3,436 and $11,838, and the average window at about $750. The 2025 Cost vs Value report's Des Moines page lists $20,569 for its model vinyl window replacement and $25,571 for wood. Cost vs Value prices one defined model project, so compare it with care. The spread comes down to how many openings you replace, the frame, the glass and how much of the old frame comes out. Your actual price comes from a free estimate on your windows.

Cost by frame material

Angi's 2026 guide lists per-window costs of $100 to $900 for vinyl, $150 to $1,300 for wood, $300 to $1,200 for composite and $500 to $1,500 for fiberglass, plus $100 to $300 per window for labor. Complex jobs such as upper-story or resized openings can run $600 or more per window in labor, according to Angi. We install Alside vinyl windows and Marvin windows, so we can price both a vinyl and a fiberglass-clad option for the same opening. Your actual price comes from a free estimate.

Insert or full-frame replacement

An insert, also called a retrofit, sets a new window inside the old frame. A full-frame replacement takes the window out down to the rough opening, so we can check the framing, replace rotted sills and flash the new nailing fin to the house wrap. Angi's 2026 guide lists retrofit work at $100 to $300 per window and full-frame at $180 to $1,500. Inserts suit sound frames. Full-frame is the right call when there is rot, water damage or siding work happening at the same time. Your actual price comes from a free estimate.

Cost by window style

Angi's 2026 style table lists double-hung windows at $150 to $650, casements at $150 to $1,000, bay windows at $900 to $7,100 and bow windows at $1,500 to $6,500. Sliding and garden windows vary with size. Basement egress windows are their own project, because they often mean cutting the foundation and adding an egress well, and the City of Des Moines has a separate basement egress window policy. Your actual price comes from a free estimate.

Glass packages for Iowa winters

Glass is where Iowa homes spend money well. ENERGY STAR places Polk County in its Northern climate zone, where version 7.0 windows need a U-factor of 0.22 or lower with SHGC of 0.17 or higher, or an equal-performance option. Angi's 2026 guide lists double-pane glass at $500 to $2,000 per window and triple-pane at $1,000 to $4,000. The U.S. Department of Energy says windows can account for 30 to 40 percent of a home's winter heat loss. Our double vs. triple pane guide compares the two. Your actual price comes from a free estimate.

Permits in Des Moines

The City of Des Moines Minor Repair Permit Exemption Policy (effective July 1, 2023) lists window replacement as exempt only when every condition is met, including that the rough opening size does not change, the egress opening is not reduced and the window is not required to be safety glazing. Exempt work must still meet current code. Resizing an opening, adding an egress window or working near fire separation lines changes the answer. West Des Moines, Ankeny, Altoona and other suburbs set their own rules, so check with your city first.

Resale, lifespan and the end of the tax credit

The 2025 Cost vs Value report's Des Moines page lists vinyl window replacement at 70.3 percent of cost recouped at resale and wood at 54 percent. Angi says most properly installed windows last 15 to 20 years, with fiberglass lasting up to 40. One change for 2026: the IRS says the federal 25C credit is not allowed for property placed in service after December 31, 2025, so do not count on a tax credit this year. Our 2026 tax credit guide explains what changed.
