Window replacement cost in Washington

Window replacement: what moves the price in Washington

• Frame material

  Vinyl windows run $350-$1,500 each installed, fiberglass $400-$2,000, composite $400-$2,300, and wood $800-$3,800 (HomeGuide).

• Window type

  Single-hung and picture windows are cheapest; bay and bow windows can reach $3,000-$8,000+.

• Count

  Replacing 10 to 15 windows runs $4,500-$22,500; at 25 windows it is $11,250-$37,500.

• Permit

  Window permits are $50-$200 each, or $400-$600 total for a multi-window job, and are often only needed when you change the opening (HomeGuide). No permit fee is included here because many cities do not ask for one on same-size replacements.

Window replacement cost by metro in Washington

2 of the 7 metros sit above the statewide midpoint of $10,600, and the top-to-bottom gap is 8%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

Washington labor market for windows

Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.19 for Washington.

For glaziers (47-2121, weighted 50%) the local median is $32.14 an hour, which is 17% above the national $27.44. The middle half of them earn between $28.49 and $51.36 an hour. BLS counts 1,460 of them working in the state, 4.1 for every 10,000 jobs (US: 3.8), so the local bench is about average.

For carpenters (47-2031, weighted 40%) the local median is $35.67 an hour, which is 22% above the national $29.12. The middle half of them earn between $29.15 and $44.55 an hour. BLS counts 26,960 of them working in the state, 75.9 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.

General maintenance and repair workers (49-9071), 10% of the weighting: a median of $28.44 an hour, 19% above the US median of $23.84. The middle half of them earn between $23.20 and $34.78 an hour. About 32,450 work in the state. That is 91.4 per 10,000 jobs, compared with 98.4 nationally, so the supply of crews looks typical.

A crew paid at the 75th percentile for glaziers ($51.36 an hour) would add about $930 to the statewide midpoint; one at the 25th percentile ($28.49) would take off about $180. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

BLS counts 3,550,970 jobs across Washington (May 2025), which is 2.3% of US employment.

When Washington weather lets you replace

Season matters for windows. For each Washington metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.

Seattle has the longest comfortable season of the metros we cover in Washington at 12 months; Kennewick has the shortest at 8 (February through June and September through November). Rainfall runs from 8 inches a year in Kennewick to 57 inches in Bremerton.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
