Chimney Chase Repair in Lake Forest Park, 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 Lake Forest Park and nearby Kenmore and Shoreline.

Why chimney chase repair comes up so often in Lake Forest Park
Contemporary homes from the 60s and 70s in Lake Forest Park often have wood-framed chimney chases sided to match the house. Under heavy tree cover, needles collect on the chase cover, hold water, and speed up rust. Once the cover leaks, the framing inside the chase rots out of sight. We replace the cover with a sloped, sealed one, rebuild the chase framing and sheathing, reside it, and flash the chase where it meets the roof so needles and rain shed off cleanly.
Lake Forest Park was laid out as a residential community on the hills above the north end of Lake Washington, and it still feels like a neighborhood built into a forest. Homes range from a few older cottages and 1920s to 1940s houses near the lake to mid-century ramblers, split-levels and contemporaries from the 1950s through the 70s on steep, winding streets. Lots are large and irregular, often sloping sharply toward a creek or the road. Cedar lap siding, board-and-batten and vertical panel siding are common, and many homes have multi-level decks built out over the slope.
Tree cover is the defining condition in Lake Forest Park. Tall firs, cedars and maples shade roofs, siding and decks so heavily that some walls never dry between November and April. Needles and leaves pile into gutters and onto deck boards, and moss grows on anything horizontal. Steep lots send groundwater and surface runoff toward the uphill side of houses, so lower siding and sill plates stay wet. Homes near Lake Washington add morning fog and lake moisture to the mix.

Neighborhoods and permits in Lake Forest Park
Sheridan Heights and Horizon View sit higher on the hills, with steep lots, view decks and wind on the exposed edges. Brookside and homes along Lyon Creek and McAleer Creek sit lower in wooded ravines where shade, moss and runoff dominate. Properties near the Town Center and along Bothell Way are flatter and closer to the lake, with more fog and less slope. Uphill walls on almost any lot here tend to be the wettest side of the house.
Like-for-like repairs on a small scale often don’t need a permit, but structural work, new decks and larger replacements usually do. The City of Lake Forest Park issues building permits, and work near creeks or steep slopes may get extra review. We check with the City of Lake Forest Park before starting so there are no surprises mid-project.

Chimney chase repair in Lake Forest Park: 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.
