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 Westminster
If your Westminster home was built between 1975 and 1995, there’s a good chance your chimney cap and crown have quietly outlived their design life. Most chimney cap installations and crown repairs in Westminster run $215-$680 depending on whether we’re sealing a simple masonry crown or fabricating a custom chase cover for a prefab fireplace. Our crews work throughout Westminster weekly, from the Federal Boulevard corridor to the neighborhoods around Standley Lake, and we bring a camera down every flue before quoting anything. Call (980) 580-8641 and we’ll schedule a written-price inspection, not a flashlight look.
Why Emberly Chimney Cleaners Is Westminster’s Preferred Chimney Cap & Crown Company
Westminster’s housing stock isn’t like Denver’s. Most of the city’s 1970s through 1990s ranch and split-level homes were built with factory-made zero-clearance fireplaces inside framed wood chases, not traditional brick chimneys. That means the cap and crown problems we see out here are different: corroded galvanized chase covers, failed prefab termination caps from Majestic and Heatilator, and flashing that pulls away from the shingles where the chase meets the roof. If your tech has only worked on masonry chimneys in older Denver neighborhoods, they’re going to misdiagnose what’s happening on your roof.
Our Westminster customers consistently tell us the same thing: they wanted the price in writing before anyone started, and they wanted to see the damage themselves. Clause 4 of the Haven Standard requires a photo record on every job, and that’s been our practice since 2009, when Corrine Halstead founded the company. We photograph the chase cover, the flue, the cap, and the crown, then we sit down and show you what we found. You decide what gets fixed.
Response time to Westminster is typically 2-4 business days for non-emergency cap and crown work. If a Chinook wind event has pushed smoke back into your living room, call (980) 580-8641 and we’ll treat it as urgent. Our techs know the neighborhoods around 92nd Avenue, the subdivisions off Sheridan, and the newer builds near Legacy Ridge. We’re not guessing at your chimney’s construction; we’ve seen it before.
Our Chimney Cap & Crown Services in Westminster
Here’s what we actually do on Westminster roofs, and what it tends to run. Every job starts with a Level 2 camera inspection and ends with written documentation of what was repaired and why. No exceptions.
Cap Installation
A missing or undersized chimney cap in Westminster isn’t just a water problem, it’s a Chinook problem. Those winter wind events create rapid pressure drops that pull smoke and soot down the flue and into your living room, and a properly sized cap with the right mesh makes a measurable difference. Standard cap installation on a masonry chimney in Westminster typically runs $180-$320, including the cap and labor. For zero-clearance prefab units, the cap assembly is often a manufacturer-specific part, and we source those through our supplier network so the fit isn’t an “almost.”
Cap Replacement
Most cap replacement calls in Westminster come from homeowners who looked up at their roof and saw a rusted mess where the cap used to be. On prefab fireplaces, the thin galvanized termination caps installed in the 1980s and 1990s have a 20-30 year service life, and Westminster’s freeze-thaw cycle at 5,300-5,500 feet shortens that. We typically replace those with heavier-gauge stainless or powder-coated caps that are sized to the unit, not generic hardware-store adapters. Expect $240-$450 for standard replacement, more if the chase cover itself has rotted out and needs to be fabricated.
Crown Repair
If you have one of the older masonry chimneys in Westminster, the crown (the concrete slab that seals the top of the chimney around the flue) is your first line of defense. Freeze-thaw cycling cracks the thin mortar wash, water seeps into the flue liner, and before long the bricks below the cap start spalling: flaking, crumbling, and losing their face. We repair crowns by removing failed material, re-sloping the surface so water drains away from the flue, and sealing with a quality crown coat. Crown repair in Westminster generally runs $325-$600 depending on crown size and how much failing material needs to come off.
Crown Coating
For crowns that are structurally sound but starting to show hairline cracking or surface wear, a crown coating is a cost-effective way to buy a decade or more of service life. We use a flexible, breathable coating that expands and contracts with Westminster’s temperature swings, so it won’t crack the way rigid mortar does. Crown coating runs $195-$380 for most Westminster chimneys and can be quoted and completed in a single visit when the crown is in otherwise good shape. We’ll show you the crown on camera before and after.

BeforeAfterTrusted Brands We Service in Westminster
Westminster’s prefab fireplace stock runs heavily toward Majestic, Heatilator, and Superior units, and those manufacturers use proprietary cap and termination parts that don’t swap cleanly across brands. We keep Copperfield and Famco components in our local inventory rotation because they’re built for the kind of weather Westminster throws at a chimney, and we can fabricate custom chase covers when a galvanized original has rusted beyond repair. If your HOA requires a specific cap appearance, we can match the original profile rather than bolting on whatever’s on the truck.
Common Chimney Cap & Crown Problems We See in Westminster Homes
- Rusted galvanized chase covers. The thin steel covers installed on prefab fireplace chases in Westminster homes built from the 1970s through the 1990s routinely rust through at the folded seams after 30-40 years of UV exposure and snowmelt. When they collapse, water pours directly onto the firebox and damper.
- Failed prefab termination caps. The factory caps on zero-clearance units corrode where the collar meets the flue. We’ve pulled off caps near 92nd and Federal where the collar had corroded completely through, letting snowmelt run straight down the flue liner.
- Chinook-driven draft reversal. Westminster’s position along the Front Range means rapid pressure drops during Chinook wind events can force smoke and soot back through the damper. This isn’t a cleaning problem; it’s a cap sizing and obstruction problem that requires a specific diagnostic look.
- Spalling brick below a cracked crown. Older Westminster homes with masonry chimneys (more common in the few pre-1970s pockets of the city) suffer from freeze-thaw damage at 5,400 feet. A cracked crown lets water in, and the bricks below the cap flake and crumble within a few seasons.

FAQs - Chimney Cap & Crown in Westminster
Yes, and here’s why: the chase cover and termination cap on those factory-built units have a 20-30 year design life, and your home is now 30-35 years old. The fireplace may burn fine while the chase cover quietly rusts through at the seams, letting water run down the flue and into the firebox. We see this constantly in Westminster ranch and split-level homes built along the Federal Boulevard corridor and around 92nd Avenue. A camera inspection takes about an hour and will show you exactly what’s still solid and what’s ready to fail. Call (980) 580-8641 to book one.
Chinook winds cause real, measurable draft reversal in Westminster chimneys. The rapid pressure drop that accompanies a Chinook event changes the pressure differential between the flue interior and the living space, and smoke that would normally rise gets pushed back down. A cap that’s undersized, partially clogged, or obstructed by nearby rooflines makes this worse. If you’ve had smoke blow back into your living room during a wind event, the fix usually involves a different cap style or size, not more sweeping. We diagnose this specifically because Westminster’s position along the Front Range makes it a recurring issue that barely registers in cities farther from the mountain front.
In most cases, yes. Crown repair means removing the failed mortar, re-sloping the surface so water sheds away from the flue, and sealing with a quality crown coat. It’s a roof-level repair that doesn’t require touching the firebox, the flue liner, or the chimney structure below the crown. The exception is when water intrusion has already caused significant spalling in the bricks below the cap, which may require more extensive masonry work. We’ll show you the crown on camera before we recommend anything, so you can see the difference between a crown that can be saved and one that can’t.
Yes. We fabricate custom caps and chase covers that match the original profile your HOA approved, but in heavier-gauge material that will actually survive Westminster’s UV exposure and freeze-thaw cycles. The original caps on 1980s and 1990s prefab units were thin galvanized steel; the replacements we order through Copperfield and Famco are built to a different standard. We’ll give you a written spec sheet to take to your HOA if they need documentation. Call (980) 580-8641 and we’ll walk you through it.
Ask if they’ll put a camera down the flue before quoting. Ask if the price comes in writing before work starts. Ask if you’ll get photos of the existing damage and the finished repair. If the answer to any of those is no, you’re setting yourself up for a surprise invoice after the tech is already on your roof. Clause 1 of the Haven Standard requires a written price before work starts; Clause 4 requires a photo record. We’ve operated that way since 2009 and we’ll show you our license info on request.
