Chimney Chase Repair in Woodway, WA
Rotted wood-framed chimney chases rebuilt, sided and flashed so they stay dry. 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 Woodway and nearby Edmonds and Shoreline.

Why chimney chase repair comes up so often in Woodway
Larger Woodway homes often have more than one fireplace, and those built from the 1970s on frequently use wood-framed chases with metal flues. Under tall trees, chase caps collect needles and hold water, rusting through and sending moisture down into the framing. On the western bluff, wind also drives rain into the joints where the chase meets the roof. We remove damaged siding, rebuild rotted chase studs and plates, wrap and flash the box, and re-side it in cedar to match the house. A custom-bent metal top with a crowned center and overhanging hem finishes the job.
Woodway is a small residential town of custom homes on large, heavily treed lots tucked between Edmonds and Shoreline. Houses here were mostly built one at a time rather than as tracts, ranging from 1950s and 60s ranch homes and Northwest contemporaries to sizable two-story designs from the 1980s and 90s, plus newer estate homes. Cedar siding in lap, shingle or board-and-batten patterns is common, often stained rather than painted. Many homes have expansive decks, terraces and covered outdoor rooms facing the woods or the Sound. Long driveways, steep grades on the western side and mature landscaping mean most houses sit well back from the street.
Woodway occupies a high bluff above Puget Sound, and its western edge faces open water toward Kingston and the Olympics. Storms moving up the Sound strike those homes with wind-driven rain and salt. Farther inland, the defining condition is shade: a tall canopy of Douglas fir, western red cedar and bigleaf maple keeps roofs, siding and decks damp long after the rain stops. Needles and leaves pile up on roofs and in gutters. The result is moss, slow drying and rot that develops quietly beneath stained cedar and along roof edges.
Our crew comes out from our Woodinville office, and we also work in nearby Edmonds, Shoreline, Lynnwood and Mountlake Terrace.

Neighborhoods and permits in Woodway
Homes along the western bluff take the strongest weather from the Sound, so view-side decks, windows and siding fail first. Interior lots off Woodway Park Road are more sheltered but sit under the densest canopy, keeping roofs, fascia and lower walls wet. Near the town’s eastern edge by Firdale Village, lots are somewhat smaller and get more sun. Properties on the slopes dropping toward the shoreline face drainage and access challenges that affect decks, foundations and lower framing.
For homes inside town limits, permits go through the Town of Woodway rather than Edmonds or the county. Replacing a few siding boards or trim pieces with matching material often needs nothing, but a new deck, framing repairs or a big re-siding job usually requires approval, and wooded or steep lots can involve tree or slope review. We check with the town before starting.
