What’s different about Washington
Washington's Cascadia seismic risk, wet maritime climate, and high Seattle-area labor costs combine to raise exterior project pricing.
- Earthquake codes can require extra bracing and reinforcement.
- Moisture management and rot-resistant materials add cost in humid air.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
Expect quotes toward the higher end in Washington’s larger metros — Seattle, Spokane, and Tacoma — where labor and permit costs run above the state average, and lower in rural areas.
How the cost is built
Siding cost is driven by wall area, material (vinyl is the budget option; engineered wood and fiber cement cost more), the number of stories, and trim around windows and doors. Tearing off old siding and repairing sheathing underneath adds to the total.
Resale value
New siding is one of the highest-return exterior projects — fiber-cement siding recoups roughly 80–88% of its cost at resale, per the annual Remodeling Cost vs. Value report.
