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 Commerce City
A chimney cap and crown in Commerce City typically costs $425 to $1,750 depending on what we find, and most repairs can be scheduled within a week. We’re Emberly Chimney Cleaners, and we’ve been documenting chimney conditions with camera scans since 2009, well before insurers started asking for that kind of evidence. If your crown is cracked or your cap is missing, call (980) 580-8641 for a written quote before any work starts.
Older homes in Commerce City’s southern neighborhoods, the ones built between the 1940s and 1960s near what’s now the Suncor refinery, have chimneys that age differently than anywhere else in metro Denver. Industrial particulates settle into mortar, wind drives moisture into every crack, and freeze-thaw cycles do the rest. Our Chimney Cap & Crown crews know exactly what those conditions do to a masonry crown. We see it every week on blocks around Dahlia Street, 72nd Avenue, and Rose Hill.
We coordinate scheduling and dispatch from our Denver metro office, but the technicians who show up live and work in this area. They know Commerce City’s housing stock, its wind exposure, and what a chimney on the open plains actually needs to hold up.
Why Emberly Chimney Cleaners Is Commerce City’s Preferred Chimney Cap & Crown Company
Homeowners in Commerce City don’t want a flashlight inspection and a vague handwave about “moisture issues.” They want to see the cracks for themselves. That’s how we’ve always worked. Every visit includes a camera scan through the flue, a documented photo record of what we find, and a written price delivered before any work begins, a practice that became Clause 4 of the Haven Standard. You don’t have to take our word for anything. We show you the evidence.
Corrine Halstead has led Emberly Chimney Cleaners through more than 38,000 inspections and cleanings since 2009. Every single one came with a written price before tools came off the truck. We don’t believe in “call for a quote” because the number should already be on the page, and the technician should already be assigned when you book. Background-checked and uniformed, with a text sent when they’re on the way.
We answer the phone 24/7 with a live person. Not a voicemail. Not a web form. When you call about a cracked crown on a January afternoon in Commerce City, someone picks up, asks what you’re seeing, and gets you scheduled. That matters here more than people realize. A crown that’s been letting water into the flue for two seasons doesn’t wait for a callback.
Our Chimney Cap & Crown Services in Commerce City
Cap Installation
A properly installed cap keeps rain, snow, birds, and wind-driven debris out of the flue. In Commerce City, where northwest chinook winds push rain nearly horizontally across the open plains, an undersized or poorly fitted cap is almost as bad as no cap at all. We install Famco and Copperfield caps with proper sizing for the flue, not just whatever’s on the truck. Multi-flue systems on older bungalows get a different approach than single-flue caps on Reunion tract homes.
Cap Replacement
Rust dissolves a cap faster than people expect. Wind-loaded rain and industrial particulates in Commerce City accelerate that. When the old cap has rusted through, the wire mesh is pulling away, or the fasteners have failed, we remove and replace. We won’t patch a cap that’s already compromised, especially on a wood stove flue that sees regular use during heating season.
Crown Repair
The crown is the concrete slab at the top of the chimney. In older Commerce City homes, crowns crack early because airborne particulates from the industrial corridor settle into the mortar and weaken it. Add freeze-thaw cycles and 60 mph chinook winds, and a hairline crack becomes a full split in two winters. We cut out failed sections, rebuild with proper expansion joints, and form a drip edge so water sheets off instead of running down the brick. Crown repair in Commerce City typically runs $800 to $1,600 depending on the extent of the damage.
Crown Coating
When the crown’s still solid but showing early craze cracking, a quality coating can buy years before a full rebuild. We use Gelco crown sealant. It’s flexible enough to bridge hairline cracks, and it holds up against the UV and wind exposure Commerce City gets. Coating is not a substitute for structural repair. We’ll tell you plainly if the crown needs cutting out instead, and we’ll put that in writing.
BeforeAfterTrusted Brands We Service in Commerce City
We stock and install parts from Famco, Copperfield, and DuraFlex, so Commerce City customers aren’t waiting on shipping when a cap or crown component fails. These aren’t decorative add-ons. The materials hold up to Front Range wind loads and industrial air exposure better than the generic parts we sometimes pull off older chimneys in this area. We choose them because they’re proven, not because they’re convenient.
Common Chimney Cap & Crown Problems We See in Commerce City Homes
- Crowns spider-webbed by industrial particulates. The chimney wasn’t struck by a hammer. Years of airborne particulate settling into porous mortar, then freeze-thaw expanding those pores, created a maze of hairline cracks that now channel water into the flue.
- Missing or undersized caps on wood stove flues. In the older ranch homes south of 72nd Avenue, we regularly find active wood stoves venting through uncapped flues. Sparks, rain, and debris all pour in. A properly sized stainless cap fixes it.
- Wind-driven rain saturating cracked crowns. Commerce City has no topographic wind break. Chinook winds push rain sideways. When a crown has even a quarter-inch crack, that water gets driven deep into the flue and accelerates creosote glazing.
- Clay tile flues spalling under the crown. The visible crown crack is often the tip of it. Underneath, clay flue tiles are flaking and dropping debris. We document that with the camera scan so you see it before we quote.

FAQs - Chimney Cap & Crown in Commerce City
You need a cap even for occasional burning, and in Commerce City the reason is stronger than elsewhere: wind-driven rain enters an uncapped flue and mixes with creosote, forming a corrosive slurry that accelerates liner breakdown. Birds and rodents also nest in uncapped flues year-round, not just during burning season. A cap costs a fraction of the liner replacement you’ll need if water keeps pouring in. Call (980) 580-8641 and we’ll give you a written price for the right cap, not a generic one.
Because the homes south of the refinery were built in the 1940s through 1960s, with masonry chimneys and mortar that’s now 60 to 80 years old, they’ve absorbed decades of airborne industrial particulates. Those particulates accelerate mortar deterioration. Reunion homes, built from the 2000s onward, use prefabricated zero-clearance fireplaces or direct-vent gas units, not full masonry chimneys, so the crown problem mostly doesn’t exist there. The age of the structure and its exposure to industrial air are the two factors overwhelming everything else.
A custom cap is sized and fabricated for your specific flue dimensions and wind exposure, rather than being a stock part adapted to fit. On Commerce City’s open, flat terrain with strong northwest chinook winds, a stock cap can be undersized for the wind load, letting rain drive in around the edges. A custom cap, fabricated through our Copperfield or Famco network, seals the flue properly and stays put. You get a written scope and warranty before fabrication starts, under Haven Standard Clause 1.
If the cracks are hairline and the crown is structurally sound, yes, a Gelco crown coating will seal them and buy years of service. That’s a $350 to $600 job in Commerce City. If the crown has shifted, if pieces are missing, or if the cracks have widened into full splits from freeze-thaw, coating it would just be hiding the problem. We’ll show you the camera scan, tell you which category you’re in, and put the recommendation in writing. If a competitor quoted you a full rebuild and you’re not sure, bring us that written quote and we’ll give you a free second opinion on paper.
A damaged crown won’t make the fire dirtier, but it will absolutely make creosote more dangerous. Water entering through crown cracks mixes with creosote deposits and drives them deeper into the flue. Repeated wetting and drying turns first-degree creosote into third-degree glaze, the hard, tar-like substance that’s hardest to remove and most likely to ignite. We see this pattern repeatedly in older Commerce City homes where wood stoves are the primary heat source. The fix starts with the crown. Call (980) 580-8641 and we’ll document the full condition with photos, not opinions.
