Crown rebuilds in Bonney Lake are mostly a Lake Tapps job. The plateau subdivisions along SR 410 and in Tehaleh have prefab chimneys with metal chase covers rather than crowns, but the older lakefront homes, the cabin-era places around the lake and the scattered older properties out toward Victor Falls typically have masonry chimneys, and many are faced in river rock or stone. Their crowns were often a mortar wash troweled over the top, sometimes with stone set into it, and after decades of plateau weather that wash has cracked and let water into the core of the chimney. Loose stone near the top and white efflorescence on the face are the usual signs.
We rebuild the crown as a formed, reinforced slab that overhangs the masonry, slopes away from the flue and has a bond break around the liner so it can move without cracking, and we reset any loose stone at the top course while we are there. Our crown rebuild starts at $299 with a free quote. Bonney Lake is about 40 minutes from our Renton office via SR 167 and SR 410. The crown needs a dry window to cure, so we watch the forecast and schedule a clear day, easiest from late spring into early fall.
Symptoms
Signs Bonney Lake 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
Bonney Lake Conditions
Why this happens in Bonney Lake
Lake Tapps chimneys face open water and open plateau, so their crowns catch wind-driven rain from several directions. The region receives 40.34 inches a year by the Sea-Tac 1991-2020 normals, and the October-to-March wet season carries about 29.65 inches of it. A cracked crown fills through that whole stretch and the core of a stone-faced chimney stays saturated.
Then the plateau cold goes to work. Regional winter lows average 37 to 38F and the area touches freezing on about 60 days a year, so the water in the crown and the top courses freezes and thaws over and over. The Brick Industry Association documents that saturated masonry expands when frozen and that repeated cycles cause cracking, spalling and disintegration. That is why loose river rock at the top of a lakefront chimney almost always traces back to a failed crown, and why a summer rebuild in the 0.60-inch dryness of July holds up.
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 Bonney Lake — FAQ
The stone cap on my Lake Tapps chimney is loose. Is that a crown problem?
Almost always. On stone-faced chimneys around Lake Tapps the decorative stone at the top is set into the crown, and when the crown cracks and takes on water, the freeze-thaw cycle pops the stone loose. We rebuild the crown starting at $299 and reset the stone into it. The free quote shows whether any of the top courses need relaying too.
My Bonney Lake home has a metal chimney. Does it have a crown?
No. A factory-built chimney in a framed chase, which is what most homes along SR 410 and in Tehaleh have, is topped with a metal chase cover instead of a masonry crown. If yours is leaking or rusting, see our chase cover replacement, which starts at $299. A crown rebuild applies only to brick, block or stone chimneys.
