Chimney Chase Repair in Mountlake Terrace, 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 Mountlake Terrace and nearby Lynnwood and Edmonds.

Why chimney chase repair comes up so often in Mountlake Terrace
Most original Mountlake Terrace ramblers had simple masonry chimneys or none at all, but many later additions and remodels brought prefab fireplaces housed in wood-framed chases. Those chases often have flat or poorly sloped metal caps that rust and leak, letting rain soak the plywood and lumber inside. Inside, the studs are often punky and the living room wall next to the insert shows stains. We replace the decayed framing, apply house wrap and metal flashing, re-clad the box to blend with the original siding, and fit a peaked cover whose hemmed edges keep water off the chase walls.
Mountlake Terrace was built quickly after World War II as an affordable planned community, and its core is still made up of modest 1950s ramblers on regular grid lots. Most started as small single-story homes on crawlspaces or slabs, with cedar or plywood siding and simple gable roofs. Over the decades, owners added bedrooms, second stories, converted carports and back decks, so many houses now combine original walls with several generations of additions. Around Town Center and the light rail station, newer townhomes and apartment buildings are going up, while the Lake Ballinger area includes some larger and newer homes.
Mountlake Terrace sits on flat to gently rolling ground east of Edmonds, away from direct Sound exposure but within reach of the convergence zone showers that often settle over south Snohomish County. Rain falls steadily through fall and winter, and the low, flat terrain does not always drain quickly. Homes near Lake Ballinger and along creek corridors deal with a higher water table and occasional flooding. Ramblers built close to grade suffer from splashback, and additions tied into older walls create seams where water finds its way in.

Neighborhoods and permits in Mountlake Terrace
Around Lake Ballinger, low ground and higher groundwater keep crawlspaces and lower walls damp. Near Town Center, older ramblers sit beside new construction, and changes in grading can redirect runoff toward neighboring lots. Terrace Creek Park and the streets around it are more wooded, keeping roofs and decks shaded. Along Cedar Way and the I-5 corridor, many homes have had multiple additions, and the seams between old and new walls are where leaks usually start.
Small in-kind repairs, like replacing a few boards or a section of trim, frequently need no permit. Structural work, new decks, additions and larger siding replacements usually do, and properties near Lake Ballinger or creek corridors may involve extra review. Our crew checks with the City of Mountlake Terrace up front and files for a permit whenever one applies.

Chimney chase repair in Mountlake Terrace: 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.
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.
