How Much Does It Cost to Replace Windows in Washington State?
Most homeowners in Washington spend between $600 and $1,200 per window for replacement, including materials and labor. Costs vary based on window size, frame material, glass efficiency, and local labor rates. Wet weather and energy codes also influence which windows perform best — and how much they cost.
The table below shows average installed costs for popular metro areas using energy-efficient vinyl or fiberglass windows.
| City or Region | Average Cost per Window |
|---|---|
| Seattle Metro | $750 to $1,300 |
| Tacoma | $700 to $1,200 |
| Spokane | $650 to $1,100 |
| Yakima–Pasco–Richland–Kennewick | $600 to $1,050 |
| Everett and North Sound | $700 to $1,200 |
Seattle Window Replacement Costs
Seattle-area homeowners often pay more due to higher labor rates and demand for premium, moisture-resistant windows. Energy-efficient glass is especially important for year-round comfort.
Tacoma Window Replacement Costs
Tacoma pricing is slightly lower than Seattle, though coastal moisture still drives demand for durable frames and low-E glass.
Spokane Window Replacement Costs
Colder winters make insulation a priority in Spokane. Triple-pane or upgraded double-pane glass is more common, affecting overall cost.
Yakima–Tri-Cities Window Replacement Costs
Hot summers and cold winters mean homeowners often choose energy-efficient windows designed for temperature swings rather than moisture resistance alone.
