Balcony & Porch Repair in Seattle, WA
Rotted balconies, porches, columns and railings rebuilt safely and waterproofed. A small leak can rot both the structure and the wall behind it. We make it safe first, then rebuild framing, columns, railings and the walking surface with the flashing and waterproofing that keep it solid for years. We serve homeowners across Seattle and nearby Shoreline and Lake Forest Park.

Why balcony and porch repair comes up so often in Seattle
Covered front porches are part of nearly every older Seattle house, with tapered columns, wood floors and wide steps facing the street. Porch floors that get wind-driven rain, column bases sitting in standing water and stair stringers resting on concrete all decay from the bottom up. We lift the loads safely, replace rotted posts, beams and joists, rebuild floors and steps with proper drainage gaps, and detail column bases so they can dry. On Seattle townhomes we also repair balconies whose framing has taken on water through failed membranes.
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.
