Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Cap & Crown Across Seattle
A chimney cap or crown failure in Seattle isn’t a cosmetic issue. It’s water entering your flue, creosote turning to glaze, and on the wrong November day after a burn ban lifts, it’s a chimney fire waiting for a hot fire. Emberly Chimney Cleaners repairs, replaces, and coats chimney caps and crowns across Seattle, from Wallingford to Capitol Hill, with a written price before any work starts and a camera record of the flue before and after. Call (980) 580-8641 to schedule a cap and crown inspection with Corrine Halstead’s team.
Why Emberly Chimney Cleaners Is Seattle’s Preferred Chimney Cap & Crown Company
Seattle homeowners deal with a specific problem: damp marine air, 100-year-old brick chimneys, and shared flue stacks on attached Craftsman houses. What we see on a Ballard roof is not what a sweep sees in Spokane, and that’s why local knowledge matters. Since 2009 we’ve inspected more than 38,000 chimneys, enforcing the Haven Standard on every job: written scope before work starts, written warranty when it’s done, and a documented photo record under Clause 4. That record includes camera footage of the flue itself, not just the cap you can see from the street.
Our crews know the tight rooflines in Fremont, the shared stacks in Phinney Ridge, and the way a Queen Anne foursquare’s crown wears differently than a mid-century rambler in Northgate. Every tech is background-checked, uniformed, and shows up with a license number you can verify. When you call, a live person answers, 24 hours a day. Corrine Halstead runs the Seattle office herself, and the person who picks up the phone knows the difference between a crown repair and a crown coating.
Our Chimney Cap & Crown Services in Seattle
We handle caps and crowns as part of a complete chimney system, not as isolated fixes. Here’s what that means on a Seattle roof.
Cap Installation
A new cap keeps rain, birds, and debris out of the flue, and in Seattle the rain part matters more than anywhere in the state. We install Copperfield and Gelco stainless and copper caps sized to the flue, not adapted to it. On a 1910 Craftsman in Wallingford, we found the original terra cotta crown spalling along the back edge where rain had pooled for decades. We pulled a cracked copper cap, mixed a Crown Coat repair to reset the wash angle, and installed a Gelco multi-flue cap, then ran a Level 2 camera check on the shared stack because the neighbor’s water heater vent terminated three feet below our crown. We wanted zero path for its exhaust to draft back into the bedroom flue.
Cap Replacement
Caps rust through, crack, or get lifted by wind off the Sound. When we replace one in Seattle, we inspect the flue it was protecting. A cap that fails on a rained-on, century-old chimney has usually been letting water sit inside for months. Replacement runs us through the same written-price protocol as any other job: scope, materials, warranty, all before we touch the roof.
Crown Repair
The crown is the concrete or mortar slab that seals the top of the chimney structure around the flue. Original Craftsman-era crowns on Seattle’s shared stacks spall from decades of damp marine air, opening channels that let rain run down two flues at once and soak creosote into a sticky glaze. We see this constantly in Wallingford, Ballard, and Fremont, where the housing stock dates between 1905 and 1935. When a crown fails on a shared stack, it fails for both units, and repair means rebuilding the wash so water sheds away from every flue.
Crown Coating
When a crown is structurally sound but porous or hairline-cracked, we apply a Crown Coat resurfacing treatment that seals the surface and resets the slope. In Seattle, where crowns stay damp from October through April, coating buys years before a full rebuild is necessary. The coating is not a patch job, it’s a cementitious seal designed for exactly the moisture load Puget Sound delivers. We use materials from Gelco and DuraFlex, and every coating job gets the same camera-scan before and after so you see what changed.
Multi-Flue Cap
Attached Seattle homes, especially rows of Craftsman bungalows in Wallingford and Phinney Ridge, frequently share a single chimney stack with two or more flues. A multi-flue cap covers the entire stack with one continuous weather barrier. When your neighbor’s appliance vents into the same stack and their flue cap is missing or their crown has failed, the exhaust has a path into your flue on low-pressure damp days. We recommend multi-flue caps on almost every attached Seattle home we inspect, because the cross-draft risk is real and the fix is straightforward.
Custom Cap
Some Seattle chimneys were never built to a standard flue dimension, especially on older homes with odd terra cotta tile sizes. We fabricate custom caps, often in copper, to fit the actual flue opening. The price is quoted in writing before fabrication, so you know the number before we order material.
BeforeAfterTrusted Brands We Service in Seattle
We stock and install caps and crown materials from Copperfield, Gelco, and DuraFlex, sourced through the Haven buying network specifically to keep customer prices honest. That means when we quote a Gelco multi-flue cap on a Seattle roof, we’re quoting the actual cap that goes on, not a generic part that might arrive in two weeks. Custom copper work, which fits the look of a Capitol Hill foursquare better than a stainless unit, is fabricated to order and we tell you the lead time before work is scheduled.
Common Chimney Cap & Crown Problems We See in Seattle Homes
- Spalled crowns on original Craftsman chimneys. The mortar and concrete crowns poured between 1905 and 1935 were never designed for Seattle’s damp, freeze-thaw-light climate. We see crowns with the back edge gone, open channels running rainwater straight down two flues at once.
- Neighbor appliance vents backing into adjacent flues. On a shared stack, when a water heater vent terminates below a failed crown or missing cap, the exhaust can draft back into the next flue over. Seattle’s low-pressure damp days in November and December stack these conditions up, and carbon monoxide follows the path of least resistance.
- Creosote glaze from burn-ban firing patterns. Seattle homeowners who only burn on legal days after Puget Sound Clean Air Agency restrictions often run hot, long fires in flues that haven’t been swept in two or three seasons. The sticky creosote deposited by years of low-temperature damp burning flashes on that first intense fire.
- Rusted or lifted caps from Sound wind and salt air. Metal caps fail faster near the water. A cap that’s held by two screws and rusted through at the base will lift in the first real wind, and the flue below it is suddenly open to every rain event between October and April.

FAQs - Chimney Cap & Crown in Seattle
On a shared Seattle Craftsman stack, does a failing crown on my neighbor’s side affect my flue?
Yes. The crown is one continuous slab across the top of the stack. When it fails on one side, water channels into both flues and, in the worst cases, the adjacent flue becomes a drain path for the entire crown’s runoff. We’ve pulled camera footage from a Wallingford home where the flue serving the primary bedroom was soaked through because the crown failed entirely on the neighbor’s side. On a shared stack, the crown is shared infrastructure. Call (980) 580-8641 and we’ll run a Level 2 camera check to see what’s actually reaching your flue.
Do I need a multi-flue cap if my neighbor’s appliance vents into the same stack?
Almost always. When a neighbor’s water heater or furnace vents into a stack you share, that appliance exhaust has a path into your flue whenever the crown or individual caps allow it. Seattle’s persistent low-pressure damp days in late fall and winter make backdrafting more likely, not less. A multi-flue cap covers the entire stack as one system and cuts that cross-draft path off completely. If you’re not sure how your stack is configured, we’ll show you on camera before we recommend a single part.
I only burn on legal days after Puget Sound Clean Air Agency burn bans. How does that affect my crown and cap?
The pattern of long, hot fires after several days of no burning is the single biggest combustion risk we see on Seattle chimneys. A crown that has been quietly letting rain into the flue for months now has a creosote-soaked liner waiting for that first legal fire. The heat doesn’t care whether the creosote came from years of low-temperature damp burning, it just ignites it. Before you light that first fire after a ban, have the crown and cap checked. It’s the difference between a working fireplace and a fire in the flue. Free estimates at (980) 580-8641.
How much does a crown repair cost in Seattle compared to Bellevue or Kirkland?
Seattle crown repairs run $640 to $1,150; Bellevue and Kirkland run slightly higher on average, mostly because roof access on hillside lots is more complex. The materials are the same, the labor is the same, and the written-price guarantee applies everywhere. What changes is what we find once the camera goes down the flue, and that’s why we give you a written scope before any repair number is final.
What does the warranty cover on a cap or crown repair in Seattle?
Every cap installation, crown repair, and crown coating we do is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right. You get a written warranty with the final invoice, and the photo record from the camera inspection is your evidence of what was there before and what we left after. That’s the whole point of the Haven Standard, and it’s been that way since 2009.
If you live in Seattle and you’re looking at a rainy season with a cracked crown or a missing cap, call (980) 580-8641. Corrine Halstead and our Seattle team will put a camera on it, show you exactly what we found, and give you a written price before any work starts.
