Window, Door & Trim Repair in Kenmore, WA
We repair the rot around windows and doors and fix the leak that caused it. 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 Kenmore and nearby Bothell and Lake Forest Park.

Why window and trim repair comes up so often in Kenmore
Wood window and door trim on Kenmore homes takes a beating, especially on lake-facing walls and on shaded walls under trees. Sills hold water, trim with unprimed backs soaks it up, and sliding door thresholds rot where decks meet the house. Replacement windows installed without new flashing are common culprits. We remove the failed trim, sills and thresholds, repair the framing underneath, re-flash the openings, and install new trim primed on all sides to handle Kenmore’s wet winters.
Kenmore wraps around the north tip of Lake Washington where the Sammamish River flows in. Most of its homes were built from the 1960s through the 1980s: split-levels, ramblers and two-story houses on wooded slopes in Inglewood, Arrowhead, Moorlands and Uplake, with lakefront and view homes along the Juanita Drive side. Cedar lap, hardboard and T1-11 siding are common, and many homes have large decks facing the lake or the woods. Newer townhomes and apartments have gone up near downtown Kenmore and along Bothell Way, mixing modern construction into an older housing stock.
Kenmore gets weather from two directions. Homes near the lake catch wind-driven rain and fog rolling off Lake Washington, which hits lakeside walls and decks hard. Up the hills, tall evergreens keep siding and decks shaded, and moss grows quickly on north-facing surfaces. The Sammamish River valley at the city’s low end holds morning fog and damp air. Steady winter rain on wooded slopes means many Kenmore homes stay wet on at least one side from fall through spring.

Neighborhoods and permits in Kenmore
Homes along Juanita Drive and the lakefront take wind and spray off Lake Washington, so view decks and lakeside walls wear quickly. Inglewood and Arrowhead are hilly and heavily treed, with shade and moss on north walls and decks. Moorlands and Uplake are steep in places, sending runoff toward the uphill side of houses. Neighborhoods near Saint Edward State Park have mature forest close to the homes, while downtown has newer, denser construction.
Small like-for-like repairs usually don’t require a permit, while structural work, new decks and larger replacements usually do. The City of Kenmore handles residential permits, and lakefront or steep-slope lots can involve extra review. We check with the City of Kenmore before starting and keep you informed about what the job needs.
