Window, Door & Trim Repair in Shoreline, WA
Exterior trim, window and door repair that looks right and sheds water. Paint cracks at a trim joint, water runs behind the casing, and the sill and framing underneath slowly go soft. We replace rotted sills, jambs and trim with rot-resistant material, add head flashing and sill pans, and keep your windows whenever they are still in good shape. We serve homeowners across Shoreline and nearby Seattle and Lake Forest Park.

Why window and trim repair comes up so often in Shoreline
Shoreline homes have often had their original windows swapped for vinyl at some point, and many of those replacements were set into old openings with no new flashing or sill pan. Water gets around the frame, and the trim and sill below quietly decay. We also find sliding patio door thresholds rotted on homes with decks at floor level. We remove the soft trim and sill, check the framing underneath, rebuild the opening, flash it properly, and install new exterior trim primed on all sides.
Shoreline is mostly a postwar city. Neighborhoods like Ridgecrest, Briarcrest, Parkwood and Meridian Park filled in during the 1950s and 60s with ramblers, split-levels and daylight basement homes on generous lots. Many still have original cedar or hardboard lap siding, single-pane windows long since replaced without new flashing, and attached decks added in the 70s or 80s. Richmond Beach and Innis Arden have larger custom homes, some with view decks toward Puget Sound. Newer townhomes and apartments are rising near the light rail stations and along Aurora Avenue, which brings modern siding systems into a city of mostly older houses.
Shoreline’s west side faces Puget Sound, and storms coming down the Sound drive rain hard into west and south walls near Richmond Beach and Innis Arden. Inland, the challenge is shade and damp rather than wind. Mature evergreens, ravines along Boeing Creek and Thornton Creek, and wet winters keep decks and lower siding damp for months. Low-slope roofs on 1950s ramblers shed water close to the walls, and short eaves give siding little protection from steady rain.
Our crew comes out from our Woodinville office, and we also work in nearby Seattle, Lake Forest Park, Edmonds and Mountlake Terrace.

Neighborhoods and permits in Shoreline
Richmond Beach and Innis Arden sit on bluffs above the Sound, so wind exposure and salt air wear down paint, flashing and deck railings fastest there. Ridgecrest and North City are flatter and more suburban, with rot driven by age and short eaves. Echo Lake and Ballinger-area streets near Lake Ballinger see more morning dampness. Lots bordering Shoreview Park and the Boeing Creek ravine stay shaded and mossy, especially on north-facing walls.
Simple like-for-like repairs often don’t need a permit in Shoreline, while structural work, new decks, and larger siding or window replacements usually do. Permits are issued by the City of Shoreline. We check with the City of Shoreline before starting so the scope, the paperwork and the inspections are all lined up.
