A crown rebuild in Woodinville is often a bigger job than the same repair in a city neighborhood, simply because the chimneys are bigger. The masonry and stone-veneered stacks on the larger homes toward Cottage Lake, Wellington and the Woodinville-Duvall Road corridor are typically wide, sometimes serving two flues, and set on steep roofs well above the eave. When the crown on one of those cracks, the water that gets in has a lot of brick and veneer to damage on the way down, and loose stone at the top of a tall stack is a safety issue as well as a leak. The older brick chimneys in the Sammamish valley typically have the thinner mortar-wash crown that simply crumbles with age.
We remove the failed crown, form a new one, and pour it reinforced and sloped, with an overhang and drip edge past the stone or brick and a bond break around each flue tile. Crown rebuilds start at $299, the quote is free, and we price match a written bid and take 10-25% off. Woodinville is about 35 minutes from our Renton office. On a multi-flue crown we plan the staging during the quote visit so the pour happens in one trip. If you are not happy, we are not done.
Symptoms
Signs Woodinville 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
Woodinville Conditions
Why this happens in Woodinville
What breaks Woodinville crowns is water that sits and then freezes. The Sea-Tac 1991-2020 normals put the October-through-March wet season at about 29.65 inches, about 73 percent of the annual 40.34, and a flat crown on a shaded lot under firs does not dry between storms. Regional roofing guidance is consistent that Western Washington moss spreads fastest October through April on tree-shaded surfaces that dry slowly, and a moss mat on a crown holds even more water in the cracks.
The area touches freezing on about 60 days a year while winter lows average 37-38F, so that saturated crown freezes and thaws repeatedly. The Brick Industry Association documents that moisture in saturated masonry expands when it freezes and that repeated cycles cause cracking and spalling. A thin, flat crown has no margin; a thick, sloped, overhanging crown sheds the water before it can freeze, which is why the rebuild holds up on a wooded Woodinville lot where a patch does not.
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 Woodinville — FAQ
My Woodinville chimney has two flues. Does that change the crown rebuild?
It makes the crown larger and means two bond breaks instead of one, so each tile can move independently without cracking the pour. The process is the same otherwise. Wide two-flue crowns are common on the larger homes toward Cottage Lake and Wellington, and we quote them after measuring on the roof. The quote is free.
Will a new crown stop the stone veneer from coming loose?
Usually it is the main fix. On stone-veneered chimneys, loose pieces near the top almost always trace to water getting behind the veneer from a cracked crown and then freezing. A sloped crown with an overhang keeps that water off the face. We re-set any stone that has already let go as part of the same visit.
