Repairs, rebuilds and new composite decks, built on solid framing with the flashing done right. Soft boards, wobbly railings and a dark line where the deck meets the house usually mean water has reached the joists or the ledger. We check the whole structure first, repair what can be saved and rebuild what cannot, with flashed ledgers, taped joists and posts that stay dry. We serve homeowners across Seattle and nearby Shoreline and Lake Forest Park.
Why deck repair comes up so often in Seattle
Backyard decks on Seattle city lots tend to be small, low and tucked into shade, which is hard on wood. Many were built decades ago by a previous owner and bolted or nailed to the house with no ledger flashing, so the rim joist behind the deck stays wet. Townhome rooftop decks bring their own issues with membranes and drains. We check framing, ledger connections, stair stringers and railings, repair what can be saved, and rebuild in cedar or composite when the structure is past saving. Seattle railing and stair rules matter here, so we build to them.
Most of the Seattle homes we work on are north of the Ship Canal. Ballard, Wallingford, Greenwood and Ravenna are full of Craftsman bungalows and foursquares from the early 1900s, along with brick-and-stucco Tudors from the 1920s and 30s. Many still wear their original old-growth cedar lap siding or shingles, nailed straight to board sheathing with no house wrap behind. Farther north, Lake City, Northgate and Maple Leaf filled in after the war with ramblers and daylight basements. Narrow city lots, alleys and tight side yards are the norm, and newer three-story townhomes with rooftop decks and mixed siding have replaced many older houses near the commercial streets.
Seattle’s winters are long, gray and drizzly rather than stormy, so exterior wood rarely gets a full drying day from October into spring. On homes near the water, wind off Puget Sound or Lake Washington pushes rain sideways into the exposed walls. Tight lot spacing works against drying too, because a wall that faces a neighbor five feet away almost never sees direct sun. The result is slow, steady decay at window sills, siding butt ends, deck ledgers and porch floors rather than one dramatic failure.
Our crew comes out from our Woodinville office, and we also work in nearby Shoreline, Lake Forest Park, Edmonds and Kirkland.

Neighborhoods and permits in Seattle
Conditions change block to block. Magnolia and the Ballard bluffs take open wind off the Sound, so west and south walls weather fastest. Laurelhurst and View Ridge face Lake Washington with similar lake-driven rain. Ravenna and the Thornton Creek corridor through Lake City sit under big trees in damp ravines, where moss and shade keep siding wet. Phinney Ridge and Queen Anne get more sun but more wind, while dense Fremont and Wallingford blocks shade each other.
Small like-for-like repairs often don’t need a permit, but structural work, new decks, and larger siding or window replacements usually do. The City of Seattle handles permits through its Department of Construction and Inspections, and homes in historic districts may need extra review. We check with the City of Seattle before starting and tell you up front if a permit is part of the job.

Deck contractor in Seattle: cost and timing
Most common causes
Posts sitting in water
Posts buried in soil or set flat on concrete wick water up and rot from the base.
Ledger without flashing
Water runs behind the board that ties the deck to the house and rots both the ledger and the rim joist.
Old hardware
Rusted nails, hangers and bolts lose their hold, which makes railings and stairs loose and unsafe.
What drives the price in Seattle
Deck work in Seattle is priced by size, height, the condition of the framing and the materials you choose. Replacing boards and railings on solid framing costs much less than a full rebuild, and composite costs more up front than wood but saves on upkeep. After the free inspection you get a written price with options.
Typical timeline
Board and railing repairs usually take a few days. A full rebuild or new deck typically takes one to three weeks, plus any permit time.
