Chimney Chase Repair in Bellevue, 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 Bellevue and nearby Sammamish and Redmond.

Why chimney chase repair comes up so often in Bellevue
Wood-framed chimney chases are common on 1970s through 90s Bellevue homes, especially in Newport Hills and the Eastgate area. The steel caps on top were usually flat, so water pools, rust eats through, and the chase framing below rots quietly for years. By the time a homeowner sees stains near the fireplace, the siding and plywood around the chase are often soft. A new pitched cover with a drip edge goes on top, softened framing and plywood are rebuilt, and the roof-to-chase joint gets fresh flashing. Chase siding is replaced to match the house.
Bellevue’s housing grew outward from the lake in waves. Lake Hills and Crossroads filled with 1950s and 60s ramblers and split-levels, many still wearing original cedar lap or board-and-batten siding under several coats of paint. Somerset and Newport Hills added 1960s and 70s daylight-basement homes built to catch views, often with tall decks hung off the downhill side. Bridle Trails has larger wooded lots and custom houses, while West Bellevue and Enatai have seen many older homes replaced by large rebuilds. Remodels are everywhere, so a single house can mix original wood siding, newer fiber cement on an addition, and a composite deck from the last decade.
Bellevue sits between two lakes, and the weather on a given wall depends a lot on elevation and tree cover. Hilltop homes in Somerset and on the Cougar Mountain side catch wind-driven rain and the occasional hard freeze, while lower lots near Mercer Slough and Kelsey Creek stay cool and damp. Long gray winters mean wood rarely dries between October and spring. Big conifers drop needles that clog gutters and hold moisture against roof edges and deck boards, which is where much of the decay we see begins.

Neighborhoods and permits in Bellevue
Lake Hills and Crossroads ramblers sit low to the ground, so rot shows up at sill plates, lower siding courses and entry steps. Somerset and Newport Hills homes face exposure instead: view-side windows, tall deck posts and ledgers take the brunt of storms. In Bridle Trails, deep shade and big trees keep roofs and trim wet. Near West Lake Sammamish and Enatai, lake moisture and sloped lots stress decks, stairs and retaining areas below the house.
Small like-for-like repairs, such as replacing a few rotted boards or a section of trim, often don’t need a permit. Structural work, new decks, larger siding replacements and changes to framing usually do. Before any of that begins, we confirm the requirements with the City of Bellevue and handle the paperwork when a permit is required, so inspections fit into the schedule rather than stalling it.

No cricket behind wide chases

Siding without a barrier
Many chases were sided without house wrap, so any leak reaches the sheathing.
Flat or rusted chase cover
Water pools on top and leaks into the chase through rust holes and seams.
