Chimney Chase Repair in Kenmore, WA
Chimney chase rot repair: framing, sheathing, siding, flashing and a new chase cover. It is a tall box exposed to weather on every side, and a rusted cover or missing roof flashing can let water run inside it for years. We strip the chase, rebuild the framing and sheathing, and finish it with new siding, flashing and a sloped cover that sheds water. We serve homeowners across Kenmore and nearby Bothell and Lake Forest Park.

Why chimney chase repair comes up so often in Kenmore
Kenmore homes from the 70s and 80s frequently have wood-framed chimney chases with a metal cover on top. After a few decades those covers rust through or sag, and water drains into the chase where it rots the framing and the siding from the inside. We replace the chase cover with a sloped, sealed one, rebuild any rotted framing and sheathing, reside the chase to match the house, and flash the joint where the chase meets the roof.
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.

Most common causes
Flat or rusted chase cover
Water pools on top and leaks into the chase through rust holes and seams.
Siding without a barrier
Many chases were sided without house wrap, so any leak reaches the sheathing.
Missing step and counter flashing
Where the chase meets the roof, water runs into the framing.
