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

Why chimney chase repair comes up so often in Redmond
Wood-framed chimney chases with factory-built fireplaces were very popular in Redmond subdivisions from the 1980s on. Their flat metal caps rust over time, and once water gets in, it rots the chase framing and siding from the inside. Shaded roofs on Education Hill and in Bear Creek keep chases damp, accelerating the decay. Our crew swaps the cap for a pitched, correctly fitted cover, rebuilds the chase framing and sheathing where it has softened, and install new siding to match the house. Step and counter flashing at the roof line are redone so the chase sheds water from every side.
Redmond grew quickly from the 1970s onward, and its housing reflects that. Education Hill and Grass Lawn are full of 1970s and 80s two-story homes and split-levels, many with cedar or hardboard lap siding and attached wood decks. Idylwood and the slopes toward Lake Sammamish have a mix of older cabins converted to year-round homes and newer view houses. Bear Creek and the hills to the east have larger 1980s through 2000s homes on wooded lots. Downtown and Overlake have added many townhomes and apartments in the last two decades, often with small balconies and mixed siding materials.
The Sammamish River valley runs through the middle of Redmond, and cool air and fog settle there on winter mornings, keeping lower walls and decks wet longer. The surrounding hills, especially Education Hill and the Bear Creek area, are heavily wooded, so many homes sit in shade for most of the day. Rain comes in long, steady stretches rather than short bursts. Wood that never fully dries between storms is the pattern behind much of the rot we find, along with moss on roof edges and decks.
Our crew comes out from our Woodinville office, and we also work in nearby Sammamish, Woodinville, Kirkland and Bellevue.

Neighborhoods and permits in Redmond
Education Hill homes stay shaded under big trees, and the damage concentrates at north walls, fascia and decks. Grass Lawn and Overlake have more sun but older flashing details, so window sills and roof-to-wall joints fail first. Idylwood, close to Lake Sammamish, sees moisture at lower siding and docks or stairs near the water. Out toward Bear Creek, larger homes with tall walls and big decks carry the most exposed surface.
Swapping out a few rotted siding boards or a small section of trim like-for-like often doesn’t need a permit. Replacing joists, posts or wall framing, building a new deck, or residing a large wall is a different story. Our office contacts the City of Redmond ahead of time, files what is required, and lines up inspections so the homeowner isn’t stuck chasing paperwork.
