Siding Replacement Cost in Washington (2026)

Re-siding a 1,500 sq ft home in Washington typically runs $12,000–$30,500, with fiber-cement plank (Hardie or LP SmartSide-style) the dominant residential cladding choice. Puget Sound and Pacific coast salt-haze plus Olympic Peninsula sustained rainfall (Forks 100+ inches/year) corrode galvanized fasteners on shoreline re-sides within 7-10 years, mandating stainless on all coastal cedar and fiber-cement — and Cascade WUI overlay across Chelan, Okanogan, and Yakima counties drove Class A ignition-resistant cladding adoption after the 2014 Carlton Complex and 2015 Okanogan Complex wildfires.

How siding replacement costs vary in Washington

State-specific code or insurance rule: Washington L&I requires every contractor performing residential or commercial work to register as a General Contractor or Specialty Contractor under RCW 18.27 — and unique to Washington, the Specialty Contractor registration is restricted to specific scope categories (Roofing, Plumbing, HVAC, Electrical) but not siding, meaning Washington siding contractors register under the General Contractor classification with a $12,000 surety bond and $250,000 liability insurance.
