Siding is your home’s primary defense against moisture intrusion, and in the Pacific Northwest, that job never stops. Seattle’s combination of wind-driven rain, persistent dampness, and seasonal temperature swings means your siding must perform year-round. When siding fails, moisture reaches the sheathing and framing behind it, leading to rot, mold, and structural damage that is far more expensive to fix than the siding itself.

Systems & Options
Siding Systems We Install
Vinyl Siding
The most affordable option with a wide range of colors and profiles. No painting needed, low maintenance.
Fiber Cement (James Hardie)
The gold standard for Seattle. Resists moisture, rot, insects, and fire. Holds paint exceptionally well.
Cedar Siding
Natural beauty and the classic PNW aesthetic. Naturally rot-resistant but requires regular staining every 3 to 5 years.
Engineered Wood
LP SmartSide and similar products deliver real-wood looks with much better moisture and impact resistance.
Composite Siding
Combines wood fibers and polymers for durability and low maintenance. Resists moisture, insects, and UV fading.

Built for Pacific Northwest Conditions
Siding in Seattle's Climate
37+ inches of annual rain, 150+ overcast days, salt-air drift off Puget Sound, freeze-thaw at higher elevations. Every siding project we deliver is spec'd for what Seattle actually throws at it.
Built to Shed PNW Rain
Seattle averages 37+ inches of rain per year. We install house wrap, flashing, and lap details engineered to channel water away from sheathing instead of trapping it behind your walls.
Moisture and Rot Resistance
Fiber cement and engineered composites resist swelling, warping, and rot in our damp climate. We pair the right material with proper kick-out flashing and weep details to keep framing dry.
Mold and Mildew Defense
Shaded, north-facing walls in the PNW are mold-prone. We specify primed, factory-finished products and maintain proper clearances at grade and roof intersections to slow biological growth.
UV Fade and Wind Exposure
Color-locked Hardie ColorPlus and premium vinyl finishes hold up to summer UV without fading. Fasteners and overlap patterns are spec'd for gusty waterfront and ridge-line exposures.
