Seattle Deck Builders Who Build to Code
Custom decks, composite decking, and repairs engineered for Seattle's wet climate. We handle permits, ledger board ties, and structural work your deck actually needs.
Decking Services Built for Seattle's Climate
Seattle's constant moisture and shade demand decks that drain fast and resist rot. We build with proper joists, footings, and material choices that stand up to decades of drizzle.
Composite Decking: Low-Maintenance Outdoor Living
Capped composite decking eliminates splinters, rot, and annual staining cycles—critical in Seattle's wet climate. We install premium 4-sided capped products with 25+ year fade and stain warranties, so your deck stays beautiful without the maintenance burden of traditional wood.
Custom Deck Building for Seattle Homes
From steep Magnolia lots to view corridors in Queen Anne, we design and build decks that fit your home's architecture and terrain. We handle permits, structural calculations, and material selection—ensuring your deck meets IRC code and performs through Seattle's rainy seasons.
Deck Staining & Sealing: Protection & Renewal
Seattle's moisture and shade accelerate mildew and gray weathering on wood decks. Our brightening process uses oxalic acid to neutralize tannin stains, followed by professional sealing to protect against the 37 inches of annual rainfall and sustained humidity.
New Deck Installation Built to Code
We build new decks from footings through finish, following IRC Section R507 standards for ledger attachment, joist spacing, and post depth in Seattle's marine clay soil. Proper flashing and ledger connection prevent the rot and collapse risks that plague improperly installed decks.
Pergola & Patio Cover Installation
Extend your outdoor season with a cedar or composite pergola, or add a solid roof cover for year-round shade. We design covers to handle Seattle's snow load requirements and ensure proper drainage so water doesn't pool on joists during winter rains.
Deck Repair & Structural Restoration
Rotting boards, soft joists, and corroded fasteners are common on older Seattle decks exposed to constant moisture. We identify structural issues early and repair ledger connections, replace damaged framing, and restore railings to safe, code-compliant standards.
Deck Railing Installation & Upgrades
IRC R312 requires 42-inch railings on decks over 30 inches high. We install wood, aluminum, cable, and glass railings that meet code, complement your home's style, and withstand salt air corrosion in neighborhoods like Alki and Magnolia Bluff.
Pergola Installation: Design & Structure
Custom pergolas add character and defined outdoor space to Craftsman bungalows and modern Northwest homes alike. We build attached and freestanding designs in cedar or composite, with proper post footings for Seattle's soil conditions and slope challenges.
Why Seattle Homeowners Choose Deck Doctor
We understand Seattle lots—steep grades in Queen Anne and Magnolia, tree canopy in Ravenna, salt air on Alki. Every deck is engineered to IRC Section R507 and sized for your specific site.
Licensed & Insured in Washington
We hold a current Washington State contractor license and carry full liability coverage on every Seattle-area project. Your deck work is protected from start to finish, and we handle all permit filings with King County and your local jurisdiction.
Code-Compliant Design & Planning
We handle permit requirements, span calculations, footing design, and ledger board tie-in from the start. Your custom deck plan accounts for Seattle's wet climate, marine clay soil conditions, and structural requirements—no surprises during inspection.
Warranty That Transfers to Owners
Our engineered framing and installation work carry a transferable warranty that protects future homeowners. This matters in Seattle's market, where deck durability directly affects resale value and buyer confidence.
Inspection-Ready Framing & Fasteners
We build to code the first time. Proper footing sizing, ledger board anchoring, joist spacing, and coated or stainless fasteners (critical for salt-laden air near Puget Sound) mean your deck passes municipal inspection without callbacks or corrections.
Before & After: Seattle Deck Replacements
From rotted ledger boards to sagging joists, we've restored and rebuilt decks across Ballard, Capitol Hill, and West Seattle. See how proper footings and tie-ins transform problem decks.
