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 Lafayette
A chimney cap and crown replacement in Lafayette typically runs $400 to $1,400 depending on flue count, crown condition, and whether you’re dealing with a coal-era masonry stack or a newer prefabricated chase. Most Lafayette jobs are quoted, scheduled, and completed within five to seven business days. That’s the short answer. The longer one matters more here than in most towns, because Lafayette’s housing stock is split between late-1800s worker cottages and post-1970s tract homes, and each demands a different cap and crown approach. Call (980) 580-8641 and we’ll walk you through what applies to your chimney.
We know Lafayette’s chimneys because we’ve spent fifteen years inside them. Our Chimney Cap & Crown team runs camera inspections before touching anything, which means you see the crown cracks and cap damage on screen before a dollar changes hands. That matters in a town where half the chimneys predate the First World War and the other half were built with 1990s prefabricated components that fail in their own way. Dispatch and scheduling for Lafayette run through our San Francisco Bay Area office; crews are local, background-checked, and assigned by name.
Why Emberly Chimney Cleaners Is Lafayette’s Preferred Chimney Cap & Crown Company
Lafayette homeowners call us for two reasons: evidence and pricing. Both are written down before work begins. The 365-Day Done Right Promise, stamped on every job under the Haven Standard, means if a cap installation or crown repair isn’t done right, we make it right. No arbitration, no fine print.
Our reputation in Lafayette comes from showing homeowners what we found. Clause 4 of the Haven Standard has required a documented photo record on every job since 2009. That’s not a recent add-on. It’s the reason Old Town residents with coal-era shared flues trust us to explain what’s actually happening inside a stack they’ve never seen. Corrine Halstead, who leads our team, made camera-scan documentation the default inspection standard years before insurers or regulators asked for it.
When a Lafayette homeowner books a cap or crown job, they get a named tech, a text when that tech is on the way, and a written scope with a line-item price. No one shows up and announces a surcharge. No one “discovers” a problem you can’t verify. The camera footage is yours to see.
Our Chimney Cap & Crown Services in Lafayette
Cap Installation
A new cap on a Lafayette chimney does more than keep rain out. On Old Town cottages with original multi-flue masonry stacks, the right cap prevents backdrafting during those 60 to 100 mph Chinook gusts that sweep down from the Front Range through the Lafayette corridor. We size caps to the flue, not the chimney, because a cap built for one flue on a shared stack can choke the draft of an adjacent flue. Materials come from Copperfield and Olympia Chimney through our buying network, which keeps pricing honest. Typical cap installation in Lafayette runs $450 to $950 installed.
Cap Replacement
Wind-hammered caps are a Lafayette specialty of ours. The downslope winds that hit this part of the Front Range physically loosen multi-flue caps and lift flashing, exposing crowns to rain, animals, and freeze-thaw cycling. We replace caps that have lost their grip, rusted through at the mounting legs, or been bent by a fallen branch from one of Old Town’s mature cottonwoods. A replacement cap in Lafayette runs $500 to $1,100, including removal of the old cap and a camera check of the flue below it. You get a written warranty before work starts, not after.
Crown Repair
Lafayette’s crown problems follow a pattern: sunny 60 degree afternoons followed by hard overnight freezes. That swing forces moisture into hairline cracks, which freeze, expand, and spall the concrete. Older Old Town chimneys with original soft mortar degrade even faster. We repair crowns with Gelco’s CrownCoat system, which bonds to the existing crown and bridges cracks up to a quarter inch. Full crown rebuilds are quoted when the existing crown has crumbled past the point of coating. Crown repair in Lafayette runs $600 to $1,400 depending on crown size and access.
Crown Coating
When a Lafayette crown is cracked but structurally sound, we coat rather than rebuild. Gelco CrownCoat is engineered for exactly the freeze-thaw cycling Lafayette gets at 5,200 feet. The coating seals hairline cracks, waterproofs the crown surface, and buys ten to fifteen years before a rebuild is needed. We apply it after cleaning and profiling the crown surface. Coating runs $350 to $700 on a single-flue chimney, $600 to $1,000 on a multi-flue stack like those in Old Town. The price is written before we mix anything.

We stock and install parts from Copperfield, Olympia Chimney, and Gelco, sourced through the Haven buying network specifically to keep customer prices honest. That means Lafayette homeowners aren’t waiting on a parts truck from Denver for a standard cap replacement or crown coating. Copperfield caps and dampers are in our Lafayette stock. Gelco CrownCoat is on the truck. When a custom cap is needed for a coal-era flue with odd dimensions, we fabricate to spec, and you approve the drawing before anything is ordered.
Common Chimney Cap & Crown Problems We See in Lafayette Homes
- Shared-stack cross-contamination. Old Town’s attached coal-era cottages often share a masonry chimney mass, with one flue per original coal stove. When we cap or repair one flue in a shared stack, we check the adjacent flue’s draft before and after, because a cap that disrupts airflow in one flue can pull a neighbor’s appliance exhaust into living spaces during Chinook gusts.
- Freeze-thaw crown spalling. Lafayette’s 60 degree afternoons and sharp overnight freezes crack concrete crowns disproportionately fast. By the time a homeowner notices water staining on the ceiling joists near the chimney, the crown has usually been compromised for two or three winters.
- Wind-lifted caps and flashing. Downslope wind events through the Lafayette corridor routinely gust 60 to 100 mph. That’s enough to lift a multi-flue cap off its mounting, loosen sheet-metal flashing, and expose the crown to rain. We see caps missing entirely after hard wind events, usually found in a neighbor’s yard a block over.
- Undersized flues after retrofits. In Old Town, older flues were sized and angled for coal combustion. When a homeowner retrofits a wood insert or gas appliance, the flue is often undersized for the new heat output. That produces heavy glazed creosote rings or visible CO-risk gaps we find on camera. A cap or crown job on a retrofitted Lafayette chimney should always include a flue sizing check.

FAQs - Chimney Cap & Crown in Lafayette
Probably not. An unlined, unused flue in a shared Lafayette stack still affects draft dynamics inside the masonry mass. When we capped a two-flue chimney on a late-1800s Old Town cottage, the unused second flue had no liner at all, and it was silently pulling smoke from the active stove into the shared stack. Capping only the active flue would have made it worse by increasing pressure in the adjacent void. The fix was a custom multi-flue cap from Olympia Chimney sized to both flues. A Level 2 camera inspection is the only way to know what’s happening inside the stack before you spend on a cap. Call (980) 580-8641 for a free estimate.
Lafayette’s position on the Front Range puts it in a stronger downslope wind corridor than Broomfield, with gusts routinely hitting 60 to 100 mph. That physically loosens multi-flue caps and lifts flashing faster. We replace wind-failed caps in Lafayette at roughly twice the rate we see in lower-elevation cities to the east. The same winds drive negative-pressure backdrafting in fireplaces, which a properly sized cap can reduce. A cap that survives Broomfield winds may not survive a Lafayette Chinook season. Call (980) 580-8641 and we’ll look at your cap’s mounting before the next wind event.
Yes. Crown cracking is not caused by use; it’s caused by water and temperature cycling. Lafayette gets sunny 60 degree winter afternoons followed by hard overnight freezes. That freeze-thaw cycling forces moisture into micro-cracks in the crown’s concrete, expands, and spalls the surface. Every cycle widens the cracks. A fireplace that sits unused all winter still has a crown exposed to those conditions. Coating with Gelco CrownCoat is the cheapest way to stop the cycle before it becomes a rebuild. Call (980) 580-8641 for a free estimate.
Lafayette’s coal-era flues were sized for coal, not wood inserts. When a homeowner retrofits, we often find the flue is undersized for the new heat output, producing heavy glazed creosote rings or CO-risk gaps. In that situation, a custom cap has to address both weather protection and draft performance. We size the cap to the flue as-is, fabricate it to spec, and in some cases rebuild the crown with Gelco’s CrownCoat to create a proper drip edge. You approve the drawing before fabrication starts. Call (980) 580-8641 and we’ll camera-scan the flue first so the cap matches what’s actually there.
In most cases, yes. Old Town’s attached coal-era cottages often have multiple flues in a single masonry chimney, originally one per coal stove. When separate households share that stack, a cap sized for one flue can block the draft of an adjacent flue and push a neighbor’s appliance exhaust back into living spaces during high-wind events. A multi-flue cap solves that by covering all flues with a single engineered unit sized to each flue’s dimensions. We install multi-flue caps from Olympia Chimney and Copperfield. Call (980) 580-8641 for a free estimate on your specific stack.
