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 Sweep Across Denver
A standard chimney sweep in Denver typically costs $189 – $329, and the work includes a full firebox and smoke chamber cleaning, creosote removal, and a written photo report of what we found. We dispatch background-checked, uniformed techs from our Denver office to neighborhoods across the metro, from Berkeley to Wash Park to Montclair. Call (830) 251-4560 for a written price before we ever put a tool on the truck. That’s the Flint way: the number you approve is the number on the invoice.
Denver homes sit at 5,280 feet, and that changes how a chimney actually behaves. Thinner air means your fireplace or stove has to work harder to establish draft. Add in the freeze-thaw cycles that chew up chimney caps and crowns, plus the number of older bungalows and mid-century ranches still running original flue tiles, and a sweep here isn’t a cosmetic wipe-down. It’s preventive maintenance for a system that vents fire out of your living room. If you’ve been burned by a no-show or a price that moved at the door, Hank Delano and the Flint crew run a different operation. We put everything in writing, and we stand behind it for a full year.
Why Flint Chimney Sweep Is Denver’s Preferred Chimney Sweep Company
Flint Chimney Sweep is part of the Garrison Partners family, founded in 2002, and every location operates under the same written standard: a price in writing before work starts, a background-checked and uniformed technician on every call, and a 365-Day Done Right Promise on every repair. Denver homeowners get the same discipline whether they’re in a 1908 foursquare in Baker or a 1970s split-level in Virginia Village.
Our Denver customers tend to mention the same three things: the tech showed up inside the window we gave them, the work area was left cleaner than we found it, and the bill matched the quote to the dollar. That last one matters. A chimney sweep is only worth what you can verify, and we send a camera inspection report with still images so you’re looking at the same flue we are. Nothing gets recommended on our word alone. If the photo doesn’t show a problem, we say so.
We answer the phone with a live person 24 hours a day, seven days a week. No callback forms. If a covered repair fails within a year of the service date, we come back at no charge. That’s the Garrison Standard in writing.
Chimney Maintenance in Denver
Chimney maintenance in Denver is a seasonal discipline, not an optional upgrade. The mix of freeze-thaw cycles, hail, and high-efficiency appliances alongside traditional wood fireboxes means a chimney here sees more stress in one year than a chimney in a milder climate sees in three. A maintenance visit typically runs $160 – $260 and includes damper operation checks, a visual crown and cap review, smoke chamber cleaning, and creosote stage assessment.
Annual Sweep and Fireplace Cleaning
For wood-burning fireplaces in Denver, one sweep per cord of wood burned, or once a year minimum, keeps first- and second-degree creosote from hardening into something a brush can’t remove. We clean the firebox floor, the smoke shelf, the damper frame, and the connector pipe where accessible. Gas log sets get cleaned too: corrosive byproducts collect on the logs and can block the flue even though there’s no visible soot.
Soot and Creosote Removal
First-degree creosote looks like flaky soot and brushes off with a standard sweep. Second-degree creosote is the bubbly, tar-like glaze that forms when chimney temperatures run low, common in Denver because thinner air slows combustion heat. When we see hardened, shiny third-degree creosote, a brush won’t cut it. That requires chemical treatment or mechanical removal, and we show you the camera footage before recommending anything.
Chimney Sweep Services in Denver
Chimney sweep services in Denver from Flint run $189 – $329 for a standard wood-burning fireplace with an accessible roof and a liner in serviceable condition. The sweep includes the firebox, smoke chamber, damper deck, and full vertical flue brushing. You’ll get a written price before the tech starts, a camera inspection photo report when it’s done, and a one-year guarantee on any repair work we perform.
Level 1 and Level 2 Inspections
A Level 1 inspection is a visual check of the readily accessible parts of the chimney, the firebox, and the flue. Level 2 adds camera scanning of the entire flue liner, which is what you want after a chimney fire, before buying or selling a house, or after a hail event in Denver. A Level 2 on a typical Denver home runs $189 – $285 when done with a sweep. If the house changed hands recently and you inherited a fireplace with no service records, get the camera in there.
Fireplace and Flue Liner Work
When the camera shows cracked flue tiles or gaps in the mortar joints, we talk through relining options using DuraFlex or Copperfield stainless liners, specifying the brand by the job rather than by margin. A liner isn’t something we sell you on. If the photos don’t support it, we’ll tell you to wait. The Garribone Standard means recommending work only when it’s documented, not when it’s convenient.

Trusted Brands We Service in Denver
We keep our trucks stocked for the equipment Denver homeowners already have: Famco chimney caps, Copperfield dampers, DuraFlex stainless steel liners. That means when a hailstorm dents a cap near Cheesman Park or a damper seizes in a Montclair ranch, we’re not ordering parts and making you wait. We install what we bring, and we specify the brand before the job starts so you can look it up yourself. We’ll also service HeatShield components where they’re already installed, including resealing joints the camera shows have opened up.
Common Chimney Sweep Problems We See in Denver Homes
- Third-degree creosote hiding behind a “clean” looking flue. From the roof, a chimney can look fine while the mid-flue is glazed with hardened tar. We camera-scan every sweep so that condition doesn’t go unnoticed until a chimney fire gives it away.
- Dented chimney caps and cracked crowns from Denver hailstorms. A creased cap lets water drip straight down the flue liner, and a cracked crown lets it soak into masonry. Freeze-thaw does the rest: water freezes, expands, and spalls brick faces. We see this constantly across west Denver’s older housing stock.
- Draft failures at altitude. Homes in the Denver metro, especially anywhere east of I-25 where the air is already thinner and stack effect weaker, often struggle with smoke backdrafting on startup. Sometimes it’s a simple damper issue. Sometimes the flue is oversized for the fuel actually being burned, and the smoke can’t get moving.
- Flue tiles spalled and missing. Original clay tile liners in 1920s through 1960s Denver homes crack from decades of thermal cycling. A sweep that skips the camera misses this. A Level 2 inspection catches it before combustion gases find a path into the wall cavity.

FAQs About Chimney Sweep in Denver
Every 30 to 50 fires, or once a year minimum if you burn regularly. In Denver, the thinner air means fires often run cooler, which produces creosote faster, so the once-a-year schedule is the right one for most homes. If you’re unsure, call (830) 251-4560 and we’ll tell you straight what your fireplace actually needs.
A Level 2 inspection sends a camera through the entire flue liner so we can see cracks, gaps, or hidden creosote that a brush and a flashlight from the roof won’t reveal. After a chimney fire, before a home sale, or after a Denver hailstorm, it’s the baseline. You’ll see the still images yourself before any repair is recommended.
No. Hardened, glazed creosote won’t come off with a brush and needs a chemical treatment or mechanical removal method. Attempting to brush it is a waste of your money and leaves the fire risk in place. We’ll show you the camera image, tell you what we’re seeing, and quote the removal separately if it’s needed.
At 5,280 feet, the flue has to overcome thinner, colder air to establish draft, and a cold liner on a winter morning makes that harder. A damper that isn’t fully open is the other common culprit, and cracked caps pulling cold air down the chimney make it worse. We’ll diagnose which one is yours during the sweep.
We don’t promise same-day service. A chimney sweep is scheduled, and the urgency should be seasonal, not manufactured. Book before burning season in Denver and you’ll get a written price and a firm arrival window. Call (830) 251-4560 for scheduling and a free estimate.
