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.
Fast, Reliable Chimney Cap & Crown Across Des Moines
Chimney cap and crown work in Des Moines runs $340-$1,850 depending on whether we’re sealing a cracked crown or replacing a corroded cap with stainless steel. Homes along Marine View Drive and near the Des Moines Marina need this service more often than almost anywhere else in South King County, because salt-laden winds off Puget Sound eat galvanized caps and dissolve crown mortar years before the same components fail inland. We’ve been documenting open-chimney crown and cap failures in Des Moines since 2009, and every job starts with a written price before work begins. Call (980) 580-8641 for a free estimate at your Des Moines home.
Chimney caps and crowns are what keep Puget Sound rain out of places it should never be: your flue, your smoke chamber, your firebox. Cap failure is fast and visible. Crown failure is slow and nearly invisible until water has already worked its way into the brick-and-mortar stack and, eventually, into the house. See Chimney Cap & Crown for the full service picture.
Why Emberly Chimney Cleaners Is Des Moines’s Preferred Chimney Cap & Crown Company
We’re not the oldest name in Des Moines, and we don’t pretend to be. We’re the company that has inspected more than 38,000 chimneys since 2009, every one with a written price before work started and a documented photo record when it was done. In Des Moines specifically, that photo record matters. When salt air has been eroding a cap and crown for years, you want to see the before and after images yourself, not take someone’s word for it.
Our crews know the streets here. We’ve worked bluff-top homes along Marine View Drive, ranch-style houses near Saltwater State Park, split-levels in the Woodmont area, and 1970s builds near the Des Moines Creek basin. Corrine Halstead leads our team, and she’s made one thing a condition of every job we take in Des Moines: no camera footage, no recommendation. If we can’t show you the failure on a screen, we won’t charge you to fix it.
We coordinate dispatching and scheduling from our Seattle office, but the crews we send to Des Moines are trained specifically on coastal chimney failure patterns. Salt corrosion, moss-driven spalling, wind-driven rain intrusion. Those aren’t abstract concepts out here. They’re the job.
Our Chimney Cap & Crown Services in Des Moines

Des Moines homes need four things more than anything else on the chimney cap and crown front: cap replacement, crown repair, crown coating, and custom caps for multi-flue stacks. Here’s what each involves when you live this close to Puget Sound.
Cap Replacement
If your cap is galvanized and more than eight years old, there’s a good chance salt air has already done serious damage. On bluff-top Des Moines homes, we routinely find caps rusted through at the mounting ring or along the mesh, even when the chimney itself looks fine. We replace with stainless steel as standard, sized to the flue opening, and sealed so wind can’t whip water sideways through the gap.

Cap Installation
New caps on existing flues, or a code-compliant cap required by an insurance company after an inspection, are straightforward work. In Des Moines, we typically install stainless, mesh-protected caps sized for the tile or liner. We’ll confirm the flue diameter, verify the crown is sound, and document the placement with photos on every install.

Crown Repair
A crown is the concrete or mortar slab that tops the chimney stack, sloped to shed water away from the flue. In Des Moines, crowns crack and spall without the freeze-thaw cycles that alert homeowners in colder climates. What happens here is different: persistent marine moisture keeps the mortar saturated, moss takes hold, roots widen hairline fractures, and the crown essentially starts dissolving from the top. We evaluate the crown by camera, identify the failure perimeter, and rebuild or recast it.

Crown Coating
If the crown is structurally in good shape but hasn’t been waterproofed, we’ll apply a flexible crown coating that stays bonded through the region’s damp winters. This is especially worth doing on Des Moines chimneys that see direct southwest wind exposure. Without a coating, a sound-looking crown can still soak up enough water to keep the brick shell underneath damp for months at a time.

Multi-Flue Cap
Homes with multiple appliance flues, or a fireplace and a furnace sharing one chimney chase, need a cap sized to cover both openings. In Des Moines’s 1950s through 1970s housing stock, multi-flue chimneys are common. We set a cap that spans the full crown width, with proper clearance for flue gases and cross-wind stability for exposed bluff-top exposures.

Custom Cap
When the crown dimensions or flue spacing don’t match stock caps, we order a fabricated cap. Copperfield and Olympia Chimney are both manufacturers we source through our buying network specifically to keep customer prices honest in Des Moines. Your written price covers the cap, the fabrication lead time, and the installation; it’s all delivered in writing before anyone starts work.

Before
AfterMaterial Reality on the Bluff: What Salt Air Does to Your Chimney
Here’s the piece of information most Des Moines homeowners never get until a sweep tells them: the air near the Sound carries enough salt and moisture to turn a galvanized steel cap into rust-bound scrap in under a decade. Inland cities like SeaTac or Federal Way might get twenty years out of a galvanized cap. On Marine View Drive, six to eight years is common; we’ve seen four. If your home sits within a few blocks of the water or faces southwest, stainless steel is not an upgrade. It’s the baseline. Corrosion on standard galvanized caps starts at the weld points and clips, then spreads to the mesh and screening. Once holes open up, rain and embers get through, and the cap is doing nothing.
Common Chimney Cap & Crown Problems We See in Des Moines Homes

- Salt-corroded galvanized caps. The mounting ring rusts through first, and wind rattles the cap loose. The result is an open flue that also lets leaves and rain into the flue.
- Crown spalling without freeze-thaw. Saturated mortar doesn’t need ice to crack. Moss roots push apart hairline fractures from the inside, and chunks of crown wash away over time.
- Chimney crowns saturated with moss. Moss on a roof is a nuisance. Moss on a chimney crown is a structural problem. It holds water directly against the masonry seam and widens every fracture it touches.
- Sheet metal flashings degraded by wind-driven rain. The flashing at the roofline is a cap and crown problem too. When it fails, water tracks down the outside of the chimney and into the smoke chamber inside.
On a ranch-style home near the Des Moines Marina, our crew found the original galvanized chimney cap rusted through and the crown mortar spalling from decades of salt air exposure. We installed a stainless steel multi-flue cap and rebuilt the crown with a waterproof coating, cutting off the moisture path that had begun to damage the flue liner. That house wasn’t a worst case. It was a Wednesday.

Why Emberly Documents Everything in Des Moines

Our name is the inspection standard we work to: NFPA 211 Level 2, camera down the flue, written scope, documented photo record. Since 2009, we’ve made camera-scan documentation the default on every job, not an optional add-on. That’s Haven Standard Clause 4. In Des Moines, where cap and crown failures are more frequent and more severe than inland, the photo record is the difference between a homeowner who can verify the problem and one who can’t. We take photos before, during, and after. You keep them. If there’s a warranty claim, there’s a record. If you’re selling the house, you have evidence the chimney was maintained.
And because we source materials through our buying network, using brands like DuraFlex and Copperfield, we’re not marking up parts at retail. You pay for the component, the labor, and the documentation. Nothing else.

FAQs - Chimney Cap & Crown in Des Moines
Every year, and every two years at minimum. Homes with direct southwest exposure to Puget Sound wind and salt air should be inspected annually, because cap and crown failures progress much faster out here than they do inland. An annual visual check plus a camera-scan inspection every two years catches crown deterioration before water reaches the flue liner or interior walls. Call (980) 580-8641 to book your Des Moines inspection.
In Des Moines, galvanized caps fail in six to ten years due to salt air and marine moisture; stainless steel caps typically last two to three times longer on bluff-top exposures. The price difference is real, but replacing a galvanized cap twice costs more than installing stainless once. We default to stainless for all marine-adjacent work, including Multi-Flue and Custom Cap jobs.
Yes. Moss holds moisture directly against the crown surface, and its root structure widens hairline fractures in the masonry. In Des Moines’s perpetually damp climate, moss is one of the primary drivers of crown failure, even without freeze-thaw cycles. We remove moss, evaluate the crown, and apply a waterproof coating when the structure is still sound.
In Des Moines, crowns corrode from the outside in. Persistent moisture keeps mortar saturated, and the surface begins to spall or crumble while the interior is still intact. You won’t necessarily see a leak yet. The crumbly crown is the warning that water is working through the top layer, and once it reaches the brick shell underneath, repair costs go up quickly. A camera inspection during a crown repair can tell you if the flue liner has already been affected. Call us before it gets worse.
Not always. If the flue openings are spaced normally and the crown is in good shape, a multi-flue cap works. If the spacing is irregular or the crown width calls for a non-standard fabrication, we order a custom cap built to the exact dimensions. Des Moines’s older ranch and split-level homes often have non-standard chimney tops, so we measure on site and include fabrication lead time in the written estimate.
For any of these services, call us at (980) 580-8641 or use the line-item estimate option on our site. Before you ever commit to anything, we’ll show you the condition of your cap and crown on camera, tell you exactly what the repair involves, and reduce it all to writing.
