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 Inspection Across Fort Collins
A chimney inspection in Fort Collins typically runs $189 – $460 depending on the level, and most inspections take under two hours from setup to summary. That’s the straight answer. We’re Alcott Chimney Sweep, led by Ruben Castellano, and we’ve inspected chimneys across Larimer County long enough to know that Fort Collins is not a Denver suburb in terms of how chimneys behave. The elevation, the Chinook wind corridor, the Old Town brick stock, the prefab units ringing CSU: those are local conditions, and they change what an inspection needs to find. Call (336) 863-3889 and you’ll get a live person, not a queue.
You’ll also know exactly who’s coming to your door. Every tech is background-checked, identity-verified, and sent to you by name and photo before arrival. When the doorbell rings, the person on the other side is the person you approved.
Why Alcott Chimney Sweep Is Fort Collins’s Preferred Chimney Inspection Company
We’ve been at this since 2002, as part of the Threshold Group family of home-service companies. In Fort Collins, that longevity matters because the housing stock here is genuinely tricky. Old Town’s late-Victorian brick homes carry original clay-tile flue liners that have absorbed a century of freeze-thaw cycling. Post-1970s rentals near CSU are full of prefabricated zero-clearance fireplaces that previous tenants never maintained. A chimney company that treats every house the same misses the findings that matter here, and we don’t do that.
Every Alcott technician passes a background check and identity verification before ever stepping onto a Fort Collins property. That’s the Threshold Standard, not an optional add-on. You get the tech’s name and photo before the truck rolls, and that tech shows a photo ID badge at your door. No exceptions, ever. If you’re home alone, or you’ve got kids napping, or you’re just done opening the door for strangers, that changes the entire experience.
We carry professional trade materials DuraFlex liner systems and Olympia Chimney caps among others, the brands chimney pros specify, not box-store substitutes. And every inspection comes with a written price before any work starts. No surprise line items at the end.
Chimney Leak in Fort Collins
A Chimney Leak in Fort Collins is never just a roof problem. It’s flue integrity, crown condition, and flashing performance under the kind of wind load that Old Town brick and newer stucco both struggle with. When we get a leak call, we don’t start caulking. We run the scope first because water entry through a chimney almost always tracks back to a structural breach, not a cosmetic one. In Fort Collins, a chimney leak inspection runs $229 – $380, and that includes the camera pass plus a written finding report with photos.
Chinook Wind-Driven Water Entry
The same downslope gusts that backdraft smoke also drive rain sideways into chimney crowns and chase covers. After a hard Chinook cycle, we see water stains on the flue interior that weren’t there three months prior. If your chimney is leaking only during wind events, that’s a flashing or crown path, not a liner crack.
Old Town Flashing Failures
On the 1900s-to-1930s brick stock, the original flashing was often set into soft mortar that’s now crumbling. The chimney looks fine from the ground. The leak starts where the masonry meets the roofline and then travels. We document it with the camera so you can see the exact path before you spend anything.
Chimney Camera Inspection in Fort Collins
A Chimney Camera Inspection in Fort Collins is the only real way to know what’s sitting inside a flue, especially a flue that’s been through decades of coal-to-gas conversion work. A camera inspection here runs $229 – $340 on its own, and it’s included in every Level 2 inspection we perform. You watch the screen as we do. If we tell you a liner needs work, you’ve already seen the cracks with your own eyes. Nothing gets recommended without visual evidence you can verify from your couch.
Coal-to-Gas Dead Flue Sections
This is the Fort Collins finding we flag more than any other. When Old Town homes converted from coal to gas in the 1950s through the 1970s, the upper flue sections were sometimes abandoned without relining or capping. The camera rolls past the active gas insert and finds intact creosote sitting in a dead section directly above it. That’s not a gas chimney that’s safe. That’s a fire hazard in a part of the chimney nobody looks at.
Clay-Tile Freeze-Thaw Fractures
At 5,000 feet on the Front Range, the temperature swing cycle is violent. A 40-degree Chinook warm spell after a hard freeze pushes water into micro-cracks and then freezes again within hours. Clay tile liners in Old Town homes show spalling and full-width fractures that lower-elevation chimneys don’t. The camera catches those early, before the flue gas escapes into the wall cavity.
Trusted Brands We Service in Fort Collins
We install and service DuraFlex liner systems, HeatShield resurfacing, Gelco, Olympia Chimney caps, Famco, and Copperfield components across the Fort Collins metro. Because we stock DuraFlex and Olympia parts locally, a liner repair or cap replacement in Old Town or midtown doesn’t wait on a backorder from Denver. If the inspection shows a failing liner, we can often schedule the fix within the week. We don’t improvise substitutes. We use what chimney professionals specify.
Common Chimney Inspection Problems We See in Fort Collins Homes
- Abandoned coal-era flue sections with intact creosote above active gas inserts. Fort Collins’s Old Town converted hundreds of chimneys from coal to gas mid-century, and many upper flues were never relined or capped. The camera finds creosote in sections the homeowner was told were dead.
- Spalled and cracked clay-tile liners from Chinook freeze-thaw cycling. Fort Collins sits in a wind corridor where temperature swings of 40 degrees or more within hours are normal. Old Town clay liners absorb that stress and crack faster than liners in more thermally stable cities.
- Underserviced prefab zero-clearance fireplaces in CSU-adjacent rentals. Tenant turnover means these units rarely get inspected. A tenant may never burn, but flue liner and firebox condition still degrade through sheer neglect, and the next tenant inherits it.
- Downdraft and backdraft conditions on Chinook days. Sixty-mile-per-hour downslope gusts push combustion gases and creosote fumes backward into living spaces. A chimney that drafts fine on a calm day can become a real problem when the wind shifts. That’s not a nuisance; that’s a safety finding.

FAQs About Chimney Inspection in Fort Collins
That smell is almost always creosote sitting in a dead flue section above a coal-to-gas conversion, and it’s a Fort Collins signature finding. The gas insert vents into a liner that was never connected to the upper flue, and the abandoned section still holds creosote from decades ago. On Chinook days, downdraft pushes those fumes into your living space. A camera inspection confirms it in under an hour. Call (336) 863-3889 and we’ll show you the source on screen.
Yes, and in Fort Collins specifically, you need it more than most. Coal-to-gas conversions left upper flue sections unlined and uncapped in many Old Town homes. The gas insert below looks clean. The dead section above still holds creosote, or its clay-tile liner is cracked from years of freeze-thaw. A camera inspection is the only way to know. We do Level 2 inspections on converted chimneys regularly, and we’ll show you exactly what’s up there before any repair is recommended.
Elevation reduces the density of air, which changes draft dynamics. Appliances tuned for sea level run dirtier here, and that deposits creosote faster than most homeowners expect. On top of that, Fort Collins is in a Chinook corridor where 60+ mph downslope gusts backdraft combustion gases into living spaces. A flue that performs adequately at lower elevation can be actively unsafe here. Our inspections account for both the altitude and the wind regime, not just the firebox.
The camera should look for spalling, full-width fractures, displaced tile sections, and creosote glaze in any dead flue section. Fort Collins clay tiles absorb freeze-thaw stress from Chinook cycles, and the damage often sits higher in the stack, invisible from the roofline. We document every finding in a written report you can hold in your hand. If we recommend a liner, you’ll have seen why on the screen.
Fort Collins sits inside the Northern Front Range Air Quality Control Region, where CDPHE enforces mandatory no-burn days during air quality events. Those days don’t stop inspections; we sweep and inspect regardless of burn restrictions. But they do change how homeowners think about the chimney. You get a limited window to legally burn, and a dirty flue or compromised liner means you’re wasting that window or, worse, backdrafting fumes inside. A clean, camera-verified flue maximizes every approved burn day.
