Crown rebuilds in Bothell are a downtown job. The city's brick chimneys are concentrated in the small historic core along Main Street and on the older houses around it; the subdivisions that make up most of Bothell have framed chases with metal chase covers, not crowns. On a brick chimney, the crown is the sloped cap of concrete on the top course that sheds water away from the flue. When it cracks, separates from the tile, or was never more than a mortar wash to begin with, rain runs straight down inside the stack. We remove the failed crown, form a new one with an overhang and drip edge, slope it to shed, and leave an expansion joint around the flue tile.
Crown rebuilds start at $299, the quote is free, and we price match plus 10–25% off. If you're not sure whether you have a crown or a chase cover, a photo from the yard settles it: a brick stack with a concrete top is a crown; a sided box with a flat metal top is a chase cover, and that replacement starts at $299. Bothell is about 35 minutes from our Renton office, and we schedule crown work for dry windows so it cures. If you're not happy, we're not done.
Symptoms
Signs Bothell homeowners notice
- Pieces of concrete or mortar missing from the top edge of the chimney
- Cracks wide enough to see daylight or fit a coin into
- The crown is flat or dished in the middle so water pools on it
- No overhang: the slab ends flush with the brick faces
- The top two or three courses of brick are spalling or loose
- A previous crown sealant is peeling off and the cracks underneath have reopened
Bothell Conditions
Why this happens in Bothell
The brick chimneys in Bothell's historic downtown are older than the city's 1992 median suggests, and their crowns have been taking the region's rain the longest. Sea-Tac normals put 40.34 inches a year on them, about 73% of it October through March, and a crown with a crack holds water through that whole stretch. The region's winter, with December lows averaging 37.1°F, about 60 days a year touching 32°F and only about 4 staying below freezing all day, means the water in that crack freezes overnight and thaws by afternoon again and again; brick industry guidance identifies repeated freeze-thaw of saturated masonry as the cause of cracking and spalling.
Downtown Bothell's mature trees keep many of these chimneys in shade, where Pacific Northwest moss spreads fastest October through April and roots into crown cracks. A cast crown with an overhang keeps the brick below it dry, and the dry season (July: 0.60 inches) is the time to pour one.
How It Works
Our chimney crown rebuild process
Remove the failed crown
We break out the old slab or mortar wash down to solid brick, protecting the flue opening so debris does not fall into the chimney.
Repair the top courses
Any loose or spalled brick in the top courses is reset or replaced so the new crown sits on sound masonry.
Form with overhang and slope
We build a form that projects past the brick faces on all sides and slopes the surface away from the flue so water runs off instead of sitting.
Pour and finish
The crown is poured in a single placement with a bond break around the flue tile so heat expansion does not crack it, and a drip edge is formed on the underside of the overhang.
Cure and seal
Once cured, we apply a breathable water repellent and, where useful, a flexible sealant at the flue joint. A new cap goes on if the old one is damaged.

Chimney Crown Rebuild in Bothell — FAQ
My Bothell home is in Canyon Park. Do I need a crown rebuild?
Probably not. Almost all Canyon Park and North Creek homes have prefab fireplaces in framed chases, which use a metal chase cover rather than a concrete crown. If water is getting in at the top, it's the cover or storm collar, and that replacement starts at $299. Send a photo or call 206-453-2045; we'll tell you which repair you need, free.
How long does a crown rebuild take on a downtown Bothell chimney?
Usually one visit to remove the old crown and form the new one, then a dry stretch for it to cure before it sees heavy rain. We schedule around the weather, which in Bothell means summer and early fall are ideal; we can work between storms in other seasons. Crown rebuilds start at $299, and we price match plus 10–25% off.
How soon can you do chimney crown rebuild in Bothell?
