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.

Why Emberly Chimney Cleaners Is Lafayette’s Preferred Chimney Cap & Crown Company
Lafayette homeowners deal with a specific set of chimney problems that just don’t show up the same way in Boulder or Broomfield. Old Town’s late-1800s worker cottages were built for coal. Modern appliances retrofitted into those flues create undersized vents, heavy creosote rings, and backdrafting conditions we catch with a camera scan on nearly every inspection. Up in the Indian Peaks and Waneka Landing subdivisions, the issues shift to prefabricated zero-clearance fireplaces with caps that don’t survive the first 80 mph Chinook wind of the season.
Our Chimney Cap & Crown in Lafayette work has built a reputation from Old Town to Baseline Road because we document everything. You get photos of your flue before and after, a written scope, and a written warranty. Clause 4 of the Haven Standard requires a photo record on every job, and we’ve done it that way on 38,000+ chimneys since 2009. When a Lafayette homeowner calls us about a neighbor’s gas furnace venting into their shared stack, we don’t guess. We run the camera and show you exactly what’s happening.
Our Chimney Cap & Crown Services in Lafayette

Every cap and crown job starts with the same question: what’s actually wrong up there? We inspect first, document what we find, and put the fix in writing. Here’s what we handle most often across Lafayette:
Cap Installation
A missing or damaged cap on a Lafayette chimney isn’t cosmetic. Open flues take in rain, snowmelt, birds, and in wildfire season, embers. We install single-flue and custom-fit caps sized to your existing flue dimensions, which matters when you’ve got a 1905 clay tile flue that’s narrower than anything manufactured today. Old Town chimneys often need a custom measurement and a custom cap, not an off-the-shelf universal fit.

Cap Replacement
Chinook downslope winds moving 60 to 100 mph through the Lafayette corridor will tear a loose single-flue cap right off the flue. We see it every winter off East Simpson Street and along Emma Street. When we replace, we check the flue tile beneath the cap for cracks or spalling first. No point putting a new cap on a failing flue.

Crown Repair
At 5,200 feet, Lafayette’s freeze-thaw cycle works hard against mortar. Sunny afternoons warm the crown, overnight freezes crack it, and after a few seasons, water migrates into the flue and dissolves the firebox smoke shelf mortar. We rebuild crowns with proper overhang and use a flexible coating to keep water out. This is the repair that prevents the four-figure liner replacement later.

Crown Coating
For crowns that haven’t failed yet but show hairline cracking, coating adds years. We use Gelco flexible sealant on Lafayette masonry crowns, which gives under thermal expansion and doesn’t crack the way a rigid mortar patch will. This is the highest-value maintenance step for Old Town chimneys that haven’t been touched in decades.

AfterTrusted Brands We Service in Lafayette
We stock and install components from Copperfield, Famco, and Gelco, chosen because they hold up to Front Range wind and freeze-thaw stress. For Lafayette homeowners with multi-flue chimneys, Famco’s multi-flue caps are our standard recommendation. For crown work on older masonry, Gelco’s flexible sealants handle the expansion and contraction that rigid products can’t. We keep common cap sizes and crown materials on our trucks, so most Lafayette jobs don’t wait on a parts order.
Common Chimney Cap & Crown Problems We See in Lafayette Homes

These aren’t hypotheticals. They’re what we document on Lafayette rooftops every week:
- Wind-lifted caps on Old Town cottages. An 80 mph Chinook gust off the foothills will lift a single-flue cap that was never mechanically fastened. The open flue then takes in rain, birds, and in wildfire season, embers. We see this every winter on coal-era homes between Public Road and the railroad corridor.
- Freeze-thaw spalling on crown edges. Lafayette’s elevation and dramatic temperature swings crack crown mortar fast. Water gets in, freezes, expands, and the crown edge breaks off in pieces. Left alone, the water migrates down into the flue and starts dissolving smoke shelf mortar.
- Shared-flue backdrafting in attached Old Town homes. Row houses and close-set cottages often share chimney stacks. When a neighbor’s gas furnace vents into a shared stack and your flue is uncapped or mis-sized, their exhaust pushes back into your living space. A properly sized and sealed cap is the fix, and it’s a safety issue, not a comfort issue.
- Undersized flues retrofitted for modern appliances. Coal-era flues were cast for coal’s lower-temperature exhaust. Put a modern gas insert or wood stove on that flue and you get accelerated creosote glaze and backdrafting. We catch this with a camera scan and show you the evidence before recommending any work.
We capped a two-story 1902 worker cottage off East Simpson Street in Old Town where the original clay tile liner had spalled into fist-sized chunks after decades of Chinook-driven freeze-thaw. Our crew pulled the old single-flue cap, rebuilt the crown with a Gelco flexible sealant, and installed a Famco multi-flue cap. The homeowner had complained of downdraft smoke whenever a neighbor’s gas furnace vented into the shared stack. The camera footage showed exactly why, and the fix stopped the backdrafting that day.

FAQs - Chimney Cap & Crown in Lafayette

Old Town chimneys were built for coal combustion, which means narrower flues, older clay tile liners, and proportions that don’t match modern wood stoves or gas inserts. A cap on one of these chimneys often needs custom fabrication because off-the-shelf caps don’t fit the original flue dimensions. The crown work is also different: older mortar is more porous and more vulnerable to Lafayette’s freeze-thaw cycles, so we use flexible sealants rather than rigid mortar patches. A 1990s Indian Peaks home with a prefab zero-clearance fireplace uses a completely different cap system, typically a manufactured cap matched to the specific unit. The inspection protocol is different, too. For an exact assessment of your chimney, call (980) 580-8641 and we’ll put a camera on it.
It very often is. In dense Old Town attached homes, chimneys sometimes share a stack. If your neighbor’s gas furnace vents into that shared stack and your flue is uncapped or mis-sized, their exhaust can backdraft into your living space. A properly sized and sealed cap with the right flue separation stops it. We diagnose this with a camera scan so you see the exhaust path rather than guess. This is a carbon monoxide concern, not just an odor issue. Call (980) 580-8641 and we’ll inspect it with the camera.
Every winter. Wind gusts over 80 mph are routine through the Lafayette corridor, and any cap that isn’t mechanically fastened to the flue is at risk. We replace wind-lifted caps every season, mostly on Old Town cottages where the original cap was installed decades ago with no mechanical attachment. If you hear rattling from your chimney during a wind event, that’s your warning sign. The fix is a proper mechanical connection plus a cap design rated for high wind. We can check yours. Call (980) 580-8641.
Yes, indirectly. A cracked crown lets water into the flue. Water hitting a warm flue lining creates a cooling effect that causes creosote to condense and adhere faster than it otherwise would. It also degrades the flue tile, creating rough surfaces where creosote accumulates. In Lafayette’s freeze-thaw climate, crown cracks are common, and we regularly find creosote buildup above the damaged crown area when we run the camera. Fix the crown, slow the creosote, protect the flue. For a documented inspection, call (980) 580-8641.
Yes. Zero-clearance fireplaces vent through a metal flue that terminates at the roof, and that termination point needs a cap just like a masonry chimney. Wind, rain, birds, and debris get into an uncapped metal flue and damage the unit. These caps are brand- and model-specific, not generic. We carry and order caps for the common prefab brands across Lafayette’s post-1970s subdivisions. If you’ve lost yours or it’s dented, call (980) 580-8641 and we’ll identify the right replacement.
