The crown is the first thing rain hits on a masonry chimney, and on Arlington's older brick chimneys near downtown, along the Stillaguamish and on the rural properties east of town, the original crown was typically a thin mortar wash that cracked long ago. Once a crown cracks, water runs down into the brick and the flue instead of off the edge. A crown rebuild removes the failed material, forms a new crown thick enough to last, slopes it away from the flue, extends it past the brick with a drip edge, and seals it. Arlington is about 60 minutes from Renton, and because a new crown needs a dry window to cure, we schedule it against the forecast.
Crown rebuild starts at $299. You get a free quote with photos of the existing crown so you can see what we see, a free second-opinion quote if another company has already priced it, and price match plus 10 to 25 percent off. We use safe, green materials, we are certified and insured, and if you are not happy, we are not done. Call 206-453-2045. If the chimney is also leaking inside, see chimney leak repair, since a crown is typically only part of the fix.
Symptoms
Signs Arlington 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
Arlington Conditions
Why this happens in Arlington
Arlington crowns fail from water and freeze-thaw, not age alone. Sea-Tac's NOAA normals, the regional reference, show 40.34 inches of annual precipitation with about 73 percent between October and March, and winter lows that average just above freezing. Water sitting in a crown crack in Arlington typically freezes overnight and thaws by noon many times each winter; the region sees roughly 60 days a year that touch 32 F but only about 4 that stay frozen all day. The Brick Industry Association documents that moisture in saturated masonry expands as it freezes and that repeated cycles cause cracking and spalling, which on a crown means pieces breaking off the edge and the crack opening to the flue.
Shade makes Arlington crowns wetter for longer. Regional guidance says Western Washington moss spreads fastest October through April on tree-shaded surfaces that dry slowly, and many Arlington chimneys sit under evergreens. A mossy crown typically stays saturated for weeks, so the shaded side of an Arlington chimney is typically where the crown fails first.
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 Arlington — FAQ
Can you rebuild an Arlington crown during the wet season?
We can, but we prefer a dry window so the crown cures properly. Summer is easiest; Sea-Tac's June through August normals total only about 3 inches of rain. In the wet season we watch the forecast, book Arlington crown rebuilds into dry stretches and cover the work while it cures. Call 206-453-2045 for the next window.
Does a new crown fix a leaking Arlington chimney by itself?
Sometimes, not always. A crown rebuild, starting at $299, stops water entering from the top, but if the flashing, cap or brick face is also letting water in, the leak continues. Our free quote covers the whole chimney top so you know whether the crown alone will solve it before you commit.
How soon can you do chimney crown rebuild in Arlington?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Arlington and the rest of Snohomish County.
