Newcastle's subdivisions are mostly framed chases with metal chimneys, so a crown rebuild here is a job for the older part of town: the brick chimneys on homes around Lake Boren, along the May Creek valley, and in the neighborhoods near the old Coal Creek townsite that predate the 1980s building boom. Those chimneys were typically topped with a thin mortar wash that has cracked after decades of Cougar Mountain weather, and the crack is where the water gets in. We remove the failed wash, form and pour a new crown that overhangs the brick with a drip edge, and leave an expansion gap around the flue tile so the new crown does not crack when the tile heats.
A crown rebuild starts at $299, the quote is free, and if you have been quoted a full top-of-chimney rebuild we will give you a free second-opinion quote, since on many of these chimneys the brick under the crown is fine. We price match and take 10 to 25 percent off. Newcastle is about 10 minutes from our North Renton office, so we can often look at the crown the same day and pour it the next dry day.
Symptoms
Signs Newcastle 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
Newcastle Conditions
Why this happens in Newcastle
A crown on a Newcastle brick chimney lives under trees. The lots around Lake Boren Park and down the May Creek ravine kept their fir canopy, and a crown in the shade of that canopy stays wet from October through April. The area's 40.34 inches of annual rain land mostly in those months, and measurable rain falls on roughly 150-156 days a year, so a flat mortar wash gets very little time to dry between storms.
The freeze does the rest. Newcastle sees about 60 days a year that touch 32F while lows average 37-38F, so water in a crown crack freezes overnight, thaws by midday, and freezes again, widening the crack each time and pushing moisture into the top courses of brick. A poured crown with an overhang and drip edge sheds that water off the brick instead of holding it, and that is the only kind we build.
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 Newcastle — FAQ
When is the best time of year to rebuild a chimney crown in Newcastle?
Summer. July and August average only 0.60 and 0.97 inches of rain, so the new crown cures without cover. We do rebuild crowns in the wet months when we can find a dry window, and we can seal a cracked crown temporarily to get you through a winter. Free quote either way.
Is a cracked crown on my older Newcastle chimney worth fixing, or should I rebuild the top?
Usually the crown alone. We give a free second-opinion quote on any bid that calls for tearing down the top courses, and more often than not the brick under the crown is sound once we look. A crown rebuild starts at $299, which is a fraction of a partial chimney rebuild.
How soon can you do chimney crown rebuild in Newcastle?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Newcastle and the rest of King County.
