Chimney Chase Repair in Snohomish, WA
We rebuild the box around your chimney and stop the leak at the top. 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 Snohomish and nearby Lake Stevens and Everett.

Why chimney chase repair comes up so often in Snohomish
Most historic homes in Snohomish have brick chimneys, but many houses built since the 1980s, along with some remodels, use a wood-framed chimney chase. Their flat metal covers rust over time and let water pour into the framing, often rotting studs and sheathing well before anyone notices. We replace the damaged framing and sheathing, install a sloped cap with drip edges that clear the siding, renew the roof flashing, and re-side the chase to match the house. On rural lots with tall trees, we also check for branch damage and debris buildup at the top of the chase.
Snohomish has one of the oldest housing stocks in the county. The historic downtown and nearby streets are lined with Victorian and Craftsman homes from the late 1800s and early 1900s, many with original wood siding, decorative trim and wraparound porches. Outside the core, you will find mid-century ramblers, 1990s and 2000s subdivisions, and farmhouses and newer custom homes on acreage in Machias, Cathcart and Clearview. Siding ranges from old-growth lap and shingle on historic homes to hardboard and fiber cement on newer houses, and covered porches are common.
The Snohomish and Pilchuck river valleys hold fog and cold, damp air, especially in fall and winter. Homes near the river and on low ground stay wet for long stretches, and many older houses sit close to the soil with siding near grade. Open farmland around town lets wind push rain into exposed walls. Rural homes with outbuildings also deal with tree shade and long driveways where water drains toward structures. That steady moisture slowly works into old-growth wood, paint and trim joints.

Neighborhoods and permits in Snohomish
Homes in the historic district near First Street and the river are the oldest and sit lowest, with the most moisture. Neighborhoods up the hill toward Avenue D and Blackman Lake have a mix of older and mid-century homes with better drainage. Newer subdivisions toward Three Lakes, Cathcart and Clearview face different issues, often flashing defects, while rural homes in Machias and the Pilchuck area deal with shade and outbuildings.
Replacing a damaged board with the same kind of board rarely triggers a permit, though structural work, new decks and larger replacements usually will. Inside city limits we confirm with the City of Snohomish, and homes in the historic district may also need design review for visible exterior changes. Rural addresses outside city limits fall under Snohomish County, which we confirm before starting.

Flat or rusted chase cover
Water pools on top and leaks into the chase through rust holes and seams.
No cricket behind wide chases
Water and debris pile up behind the chase on the uphill side of the roof.
Siding without a barrier
Many chases were sided without house wrap, so any leak reaches the sheathing.
