If your Mukilteo chimney is brick, the crown on top is the part doing the most work and usually the part in the worst shape. It's the slab that's supposed to shed rain off the top of the chimney and away from the flue tile. When it's a thin mortar wash, which is what most masons put on in past decades, it cracks, water gets into the top courses, and you start seeing loose brick, white efflorescence and rust streaks from the cap. On the factory-built chimneys in Mukilteo's newer subdivisions there's no crown; the equivalent is a chase cover, and we'll point you to that page if that's what you have.
Our crown rebuild, starting at $299, removes the cracked material, resets any loose top courses, and forms a new crown with an overhang, a drip edge and a slope, with a flexible joint at the flue tile. We'll add a cap at the same visit if you need one. Mukilteo and Picnic Point are about 45 minutes from our Renton office. We offer a free quote, a free 2nd-opinion quote on any bid you already have, and price match plus 10-25% off. If you're not happy with the crown, we're not done.

Symptoms
Signs Mukilteo 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
Mukilteo Conditions
Why this happens in Mukilteo
A crown in Mukilteo sits flat under 40.34 inches of rain a year at Sea-Tac's long-term normals, with about 73% of it arriving between October and March. Water pools in every crack, and the region's winter pattern, normal lows around 37F with roughly 60 days a year touching 32F but only about 4 staying frozen all day, freezes and thaws that water again and again. The Brick Industry Association documents that water freezing in saturated masonry pores expands and causes cracking, spalling and disintegration. A thin mortar-wash crown has no reserve against that; it breaks into plates, water gets under them, and the brick below saturates. Moss on the shaded side, which regional guidance says spreads fastest October through April, holds even more water against the top of the chimney. What we typically find on a Mukilteo masonry chimney is a crown that's gone in pieces, two or three loose top courses, and the top of the tile liner cracked. Rebuilding the crown early keeps that from becoming a partial rebuild starting at $299.
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 Mukilteo — FAQ
How can I tell if my Mukilteo chimney crown needs rebuilding or just sealing?
From the ground, look for pieces missing at the edge, brick sticking out past the top, or rust and white streaks down the side. Those point to a rebuild. A thick crown with only fine surface cracks can take a flexible sealant. We photograph it on the free quote visit and tell you which it is, starting at $299 if it's a rebuild.
When is the best time to rebuild a crown in Mukilteo?
Late summer. Sea-Tac's normals show only about 3 inches of rain from June through August, so the new crown cures without us racing a shower. It can be done in the wet season too; we schedule around the forecast and cover the work, but a dry week makes it simpler and gets it done before the November rain.
How soon can you do chimney crown rebuild in Mukilteo?
