Not every Covington chimney has a crown. The sided chases on most of the 1980s-2000s homes off Kent-Kangley Road, Timberlane and Covington Way are topped by a metal chase cover, and if that is what you have, the fix you need is a chase cover replacement starting at $299, not a crown. A crown is the concrete slab on top of a brick chimney, and in Covington those are on the older homes: the acreage properties toward Lake Sawyer and the Black Diamond side, the scattered 1960s-70s ramblers along SR 516 that predate the subdivisions. Those crowns were typically troweled flat from mortar, and after decades of plateau rain they crack and shed chunks.
We remove the failed crown, form a new one and pour it in crown mix, sloped to shed water, with a drip edge past the brick face. Crown rebuilds start at $299. We give a free quote with photos, a free second opinion if you have another bid, and we match any written price and take 10-25% off. Covington is about 20 minutes from our Renton office, and because a poured crown needs dry weather to cure, we schedule rebuilds around the forecast. If you are not happy, we are not done.
Symptoms
Signs Covington 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
Covington Conditions
Why this happens in Covington
A Covington crown spends most of the year wet. The Sea-Tac 1991-2020 normals put 40.34 inches of rain on the region annually, with about 29.65 inches, roughly 73%, falling October through March. A flat mortar crown on a brick chimney near Lake Sawyer holds that water in a film instead of shedding it, and the fir canopy over most Covington lots keeps the sun off it. Western Washington moss spreads fastest October through April on exactly that kind of shaded, slow-drying surface, and moss rooted in a crown crack keeps the crack wet.
Then it freezes. December, January and February lows average 37-38F, and about 60 days a year dip to freezing, so the saturated crown freezes at night and thaws by afternoon repeatedly. The Brick Industry Association documents that saturated masonry under repeated freeze-thaw cracks and disintegrates, and a crown, being the flattest and most exposed masonry on the house, goes first. A sloped crown with a drip edge dries in hours instead of days and gives moss nothing to hold onto.
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 Covington — FAQ
How do I know if my Covington chimney has a crown that can be rebuilt?
If the chimney is brick all the way up, it has a crown. If it is wrapped in siding to match the house, as most homes in the Timberlane and Kent-Kangley Road plats are, it has a metal chase cover instead, and a replacement starts at $299. Send us a photo from the yard or we will check during a free quote.
Can a crown be rebuilt in Covington during the winter?
It can during a dry stretch of a few days, and we cover the fresh pour, but the crown cures best from late spring through early fall. July is the driest month at 0.60 inches. If a cracked crown is actively leaking in winter, we can do a temporary seal first and schedule the rebuild for the next dry window.
How soon can you do chimney crown rebuild in Covington?
