Shoreline is mostly brick chimneys, but not entirely. Plenty of the city's mid-century ramblers have picked up a second fireplace in a family-room addition or a remodel, and nearly all of those are factory-built units in a framed, sided chase rather than brick. Newer infill houses and townhomes along Aurora and in North City use the same construction. Those chases are topped with a sheet-metal chase cover, and a galvanized cover from the 1980s or 90s is typically rusted through by now: ponding in the middle, streaking rust down the siding, and dripping into the firebox when it rains. If your Shoreline fireplace has a metal pipe and a cap instead of a brick stack, this is the repair you need.
We measure the chase and fabricate a new cover in stainless or a color-matched finish, with a cross-break so water sheds, a drip edge that clears the siding, and a sealed storm collar at the pipe. Chase cover replacement starts at $299, the quote is free, and we price match plus 10–25% off. If it turns out you have a brick chimney and a cracked crown instead, we'll say so; crown rebuilds start at $299.
Symptoms
Signs Shoreline homeowners notice
- Rust-colored streaks down the siding below the top of the chimney
- Standing water or rust pooling on top of the chimney after rain
- Water dripping onto the fireplace or staining the ceiling beside it
- Soft, swollen, or peeling siding and trim near the top of the chase
- A cover that rattles or lifts at the edges in wind
- Visible rust holes or a sagging center in the metal lid
Shoreline Conditions
Why this happens in Shoreline
A chase cover on a Shoreline addition gets the same 40.34 inches of rain a year as the brick chimney beside it, with about 29.65 inches of that falling October through March. Additions are often single-story, tucked behind the main house and under the big trees Shoreline is known for, so the chase sits low, shaded and slow to dry, the conditions under which Pacific Northwest moss spreads fastest, October through April. A galvanized cover that stays wet and mossy for six months rusts from the center out, and because the chase below is wood framing and siding rather than masonry, the water that gets through typically causes rot quickly.
Winter lows averaging about 37°F with roughly 60 days touching freezing don't hurt metal the way they hurt brick, so on a prefab chase the fix is simpler: a correctly fitted stainless cover that sheds water and outlasts the original.
How It Works
Our chimney chase cover replacement process
Measure the chase
We measure the chase, the flue pipe diameter and position, and the skirt height so the new cover fits without gaps.
Fabricate the cover
The replacement is made from stainless steel or aluminum with a cross-break, raised collar, and a drip-edge skirt over the siding.
Remove the old cover
The rusted lid comes off and we inspect and dry out the top plate. Minor wood damage is addressed before the new cover goes on.
Set and fasten
The new cover is fastened through the skirt into the sides of the chase, never through the top, and the collar is sealed to the flue pipe with high-temperature sealant.
Cap and check
We reinstall or replace the flue cap, confirm the storm collar is sealed, and photograph the finished top for you.

Chimney Chase Cover Replacement in Shoreline — FAQ
How can I tell whether my Shoreline fireplace has a chase cover or a brick crown?
Look at the outside. A brick stack with a concrete top has a crown. A boxy structure covered in siding with a metal pipe and cap sticking out of a flat metal top has a chase cover. Many Shoreline homes have one of each: the original brick fireplace and a later prefab addition. Send us a photo from the yard and we'll tell you, free.
Is stainless worth it over a galvanized replacement in Shoreline?
In this climate, yes. Galvanized covers are what rusted out in the first place, and a shaded Shoreline chase stays wet most of the winter. Stainless doesn't rust through, and the cost difference is small compared with redoing the job later. Replacement starts at $299 either way, and if you're not happy with the result, we're not done.
