Balcony & Porch Repair in Kenmore, WA
We make balconies and porches solid again and keep water out of the house. 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 Kenmore and nearby Bothell and Lake Forest Park.

Why balcony and porch repair comes up so often in Kenmore
Balconies on Kenmore view homes and newer townhomes face rain and wind with little protection, and failed decking or membranes let water into the framing. Covered porches on older homes have posts and columns that rot at the base and steps that soften where they meet the ground. We replace rotted posts, beams and joists, rebuild porch floors, steps and balcony decks, and detail every base and connection so wood stays off concrete and drains properly.
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.
Our crew comes out from our Woodinville office, and we also work in nearby Bothell, Lake Forest Park, Kirkland and Woodinville.

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.
