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 Southglenn
A chimney cap and crown replacement in Southglenn typically runs $450 to $1,800 depending on whether you need a standard cap, a multi-flue cap, or full crown rebuild with waterproofing. Most jobs in Southglenn are completed in a single visit because our crews carry materials locally and know the housing stock. If you’re seeing spalling mortar, rusted caps, or water staining around your fireplace, call (980) 580-8641 and we’ll give you a written price before any work starts.
Southglenn’s dense concentration of 1960s through 1980s ranch and bi-level homes means we see the same failures repeat across the neighborhood: cracked crowns from freeze-thaw cycling, caps ripped loose by Chinook winds, and shared flue problems in attached properties that most inspectors never flag. We know these houses because we’ve worked on hundreds of them. The layout, the roof pitch, the chase construction. That local knowledge changes what we look for and what we recommend.
Why Emberly Chimney Cleaners Is Southglenn’s Preferred Chimney Cap & Crown Company
Homeowners in Southglenn call us because we document what we find. Every visit includes a camera scan down the flue and a photo record you keep. That practice has been our standard since 2009, and it’s now Clause 4 of the Haven Standard. When we tell you your crown is cracked or your neighbor’s flue is leaking into a shared chase, you’ll see it in the images. Not our opinion. The evidence.
Our technicians are background-checked and uniformed. You’ll get a named tech assigned to your job and a text when they’re on the way. Southglenn’s streets around the old Southglenn Mall corridor, along East Otero Avenue, and through the ranch subdivisions near Arapahoe Road are part of our regular service route, so we’re in the area most weeks. Scheduling is coordinated from our Denver office, but the crews serving Southglenn live and work here locally.
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and every single one included a written price before work started and a documented record when it was done. Corrine Halstead leads the team and holds the line on that standard. If a job isn’t done right, our 365-Day Done Right Promise means we make it right. No fine print, no argument.
Our Chimney Cap & Crown Services in Southglenn
Cap Installation
Most Southglenn homes either never had a cap installed or have an original cap that’s rusted through. We install caps sized to your specific flue tile dimensions, not a universal clamp-on that leaves gaps. On ranches along University Boulevard and the neighborhoods east of Clarkson Street, we regularly replace caps on chimneys that have been open to rain and snow for decades. A new cap stops water intrusion, keeps animals out, and contains sparks.
Multi-Flue Cap
This matters more in Southglenn than almost anywhere else we work. Attached and zero-lot-line ranches here often group two or more flues in a shared masonry chase. A standard single-flue cap doesn’t address the shared crown or the gaps between flues. A multi-flue cap covers the entire chase top, sealing all flues under one lid. On East Otero Avenue near the old Southglenn Mall corridor, we found a ranch built in 1972 where both units of a semi-attached pair vented through a common stack. The neighbor’s furnace flue had spalled enough to dump exhaust into the shared chase. We installed a new multi-flue cap over both flues and rebuilt the crown, then ran a Level 2 camera inspection to confirm the chase was sealed and draft was restored.
Cap Replacement
If your existing cap is loose, rusted, or missing sections, replacement is straightforward. We remove the old cap, measure the flue, and install a properly sized replacement from Gelco or Olympia Chimney. In Southglenn, Chinook winds regularly rip poorly anchored caps off short ranch chimneys. The replacement has to be mechanically fastened, not just friction-fit. We see too many caps in this neighborhood that were simply set on top and ended up in a neighbor’s yard by February.
Crown Repair and Crown Coating
The crown is the concrete or mortar slab that seals the top of the chimney around the flue. Southglenn sees over 100 freeze-thaw cycles a year, and original crowns from the 1960s and 1970s were rarely waterproofed at construction. Water soaks in, freezes, and cracks the surface. That’s how you get spalling, efflorescence, and eventually chunks of crown falling into the flue. We repair cracks with proper flex sealant, rebuild crowns that are too far gone, and apply a crown coating that flexes with thermal movement instead of cracking. For many Southglenn homes, a crown coating alone stops the white mineral staining that keeps coming back after heavy rain.

We stock and install caps and crown materials from Gelco, Olympia Chimney, and Famco. These aren’t big-box parts. They’re fabricated for specific flue sizes and local weather conditions. Our buying network through Haven keeps pricing honest, and because we carry these materials routinely for Chimney Cap & Crown work across the metro, we rarely need to order and return for a second visit. That means faster turnaround for Southglenn homeowners and fewer days with an exposed chimney.
Common Chimney Cap & Crown Problems We See in Southglenn Homes
- Chinook wind cap failures: Sudden pressure drops during downslope wind events slam cold air down open flues and lift poorly anchored caps right off the chase. Short ranch chimneys with minimal above-roofline height are especially vulnerable. We anchor caps mechanically, not by friction alone.
- Shared chase flue gas migration: Southglenn’s attached ranches and zero-lot-line builds often group chimneys on party walls. A single uncapped or spalled flue on one unit can leak exhaust into the neighboring unit’s chase, causing smoke odors and carbon monoxide even when your own cap is fine.
- Cracked and spalling crowns from freeze-thaw cycling: Over 100 freeze-thaw cycles annually at 5,500 feet elevation means original mortar crowns from the 1960s through 1980s are now failing. Water gets in, freezes, and the crown cracks from the inside out.
- Rusted chase tops on factory-built fireplaces: Many Southglenn homes have early zero-clearance inserts with metal chase covers that are rusted through. Water runs down the flue liner, delaminates the firebox, and homeowners mistake the damp smell for creosote buildup.
Pricing for Chimney Cap & Crown in Southglenn, CO
Here’s where Southglenn pricing actually lands. A standard single-flue cap installation runs $450 to $700. Cap replacement with removal of the old cap starts around $500 and goes to $800 depending on flue size and roof access. A multi-flue cap for a shared chase runs $700 to $1,200, with custom fabrication adding $150 to $400 for unusual chase dimensions. Crown repair with crack sealing and minor patching is $375 to $650. Full crown rebuild with waterproof crown coating runs $900 to $1,800 depending on crown surface area and whether we’re working from a ladder or a rooftop staging platform.
What changes the price most in Southglenn is shared chase work and custom cap fabrication. Attached homes often require coordination with a neighbor and a wider cap than off-the-shelf sizing. That’s not a surprise fee. We write the scope and the price before anyone starts. If a competitor has given you a written estimate for the same scope, bring it in. We’ll give you a free second opinion.

FAQs - Chimney Cap & Crown in Southglenn
Chinook winds cause rapid barometric pressure drops that create sudden suction and turbulence at the chimney top. The original caps on 1970s Southglenn ranches were often friction-fit or secured with lightweight brackets never designed for 60 to 80 mph gusts. Add in the relatively short chimney stacks common on the flat-to-low-pitch roofs of that era, and there’s less structure to absorb the wind load. The fix is a mechanically anchored cap sized to your flue, not a replacement of the same flimsy design. Call (980) 580-8641 and we’ll inspect what you have before it ends up in a neighbor’s yard.
Probably, yes. Southglenn’s attached ranches and zero-lot-line homes often group chimneys in a shared masonry chase. If your neighbor’s flue is uncapped or has spalled liner tiles, exhaust can migrate through the shared chase and into your side of the wall. A multi-flue cap over the entire chase can seal the gap, but first we need to camera-scan both flues to confirm the source. This is exactly the kind of problem a standard single-home chimney inspection misses. We’ll document what we find and show you the photos.
If the efflorescence is coming from water wicking through a cracked crown, yes, a crown coating can stop it at the source once cracks are properly sealed. Efflorescence is mineral salt left behind when water migrates through masonry and evaporates. Southglenn’s freeze-thaw cycling means the crown is almost always the entry point. We repair cracks with flexible sealant, rebuild any missing sections, then apply a waterproof crown coating. If water is entering elsewhere, like through the brick face or flashing, we’ll show you on camera what’s happening before recommending anything.
Short chimney stacks on Southglenn’s 1970s ranch homes already struggle to maintain adequate draft at 5,500 feet elevation. Add a Chinook event’s sudden pressure drop and gusty downslope winds, and the chimney can reverse flow entirely, pushing smoke back into your living room. The fix is usually a combination of a properly sized cap that resists wind-driven backdraft and sometimes a draft-improving cap design. You don’t have a dirty flue. You have a stack height and pressure problem. We’ll diagnose it with a camera scan and airflow readings, not guesswork.
Annually, before burning season. Southglenn’s 100-plus freeze-thaw cycles per year and periodic Chinook wind events put more stress on caps and crowns than chimneys in most of the metro. A Level 2 camera inspection every year catches crown cracks before water damage spreads and verifies your cap is still anchored and intact. It’s included on every visit we make. The photo record goes to you, so you can compare year over year and see when a crack grows. Call (980) 580-8641 to schedule. We answer the phone 24/7.
