Chimney Chase Repair in Bothell, 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 Bothell and nearby Kenmore and Woodinville.

Why chimney chase repair comes up so often in Bothell
Many two-story homes in Bothell subdivisions have wood-framed chimney chases with metal covers. After 25 or more years those covers rust, sag and leak, and water rots the framing and siding inside the chase. We replace the cover with a sloped, sealed one, rebuild rotted chase framing and sheathing, reside the chase to match the house, and flash it properly where it meets the roof.
Bothell has a small historic core around Main Street with older homes from the early 1900s, but most houses here date from the 1970s through the 2000s. North of I-405, Canyon Park, North Creek, Thrasher’s Corner and the Queensborough area are full of two-story subdivision homes with hardboard or fiber cement siding, attached decks and builder-grade trim. Westhill and Maywood have more 60s and 70s split-levels and ramblers on wooded lots. Many homes have tight side yards and backyards that slope toward greenbelts. Newer townhomes and apartments are concentrated near downtown, Canyon Park and the North Creek business parks.
Bothell sits in the Sammamish River and North Creek valleys, with hills rising on both sides. The valleys hold fog and damp air on winter mornings, while the hillsides have heavy tree cover and greenbelts that keep walls and decks shaded. Tight lot spacing in many subdivisions means side walls rarely dry out. Long, wet winters soften hardboard siding and trim, and builder-grade flashing from the 80s and 90s is reaching the end of its useful life.
Our crew comes out from our Woodinville office, and we also work in nearby Kenmore, Woodinville, Mill Creek and Lynnwood.

Neighborhoods and permits in Bothell
Canyon Park and North Creek on the Snohomish County side have big 80s and 90s subdivisions where hardboard siding and nailed decks are aging out. Westhill and Maywood, south of downtown, are hillier and older, with mature trees and shaded lots. Homes near the Sammamish River and in the valley get more fog and dampness. Thrasher’s Corner and Queensborough have newer homes on tighter lots, often backing onto greenbelts with heavy shade.
Small like-for-like repairs often don’t need a permit, but structural work, new decks and larger replacements usually do. Permits come from the City of Bothell for homes in both the King County and Snohomish County parts of the city. We check with the City of Bothell before starting so your project is handled correctly.

Chimney chase repair in Bothell: cost and timing
Most common causes
Flat or rusted chase cover
Water pools on top and leaks into the chase through rust holes and seams.
Missing step and counter flashing
Where the chase meets the roof, water runs into the framing.
Siding without a barrier
Many chases were sided without house wrap, so any leak reaches the sheathing.
What drives the price in Bothell
Chimney chase repair in Bothell depends on the height of the chase, roof pitch and access, how much framing is rotted and whether a new cover and cricket are needed. You get a written price after the free inspection.
