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.

AfterChimney Cleaning in Denver, CO
Chimney cleaning in Denver costs between $189 and $329 for a standard sweep with a Level 1 inspection, and most jobs are completed in 60 to 90 minutes. What makes Denver different is the altitude: at 5,280 feet, wood fires burn cooler and less completely, which means creosote builds faster here than in lower cities. Add in pre-1950s brick bungalows from Capitol Hill to Baker that were originally built for coal, and you get flue conditions that require a camera, not just a brush. Call (980) 580-8641 for a written price before anyone sets foot on your roof.
Why Denver Homes Are Different
Denver’s chimney work is shaped by three things most other cities never deal with at once: altitude, temperature swings, and housing stock older than the state itself. The freeze-thaw cycle here crosses the freezing threshold roughly 60 times per year, and Chinook winds can shove temperatures 40 to 50 degrees in a single afternoon. That constant expansion and contraction spalls brick faces and blows out mortar joints on masonry chimneys faster than almost anywhere in the country. A chimney in Harvey Park or Barnum that looked fine in October can show fresh spalling by March.
The altitude compounds it. Thinner air means wood fires burn cooler and less completely, which increases the rate of creosote deposition and raises the likelihood of glazed third-degree creosote forming in a single season. And in the older core neighborhoods like Sunnyside and Berkeley, pre-1950s homes were built with coal-burning fireboxes. Those fireboxes were later converted to wood or gas, but the oversized clay tile liners remain, creating chronic draft problems. We see it on nearly every cleaning visit in those zip codes.
There’s also the regulatory layer unique to Denver. The Regional Air Quality Council issues mandatory wood-burning curtailment days across the metro each winter when temperature inversions trap particulates in the basin. On those days, burning is legally restricted. A clean flue and an efficient fireplace mean you get maximum legal use out of the limited burn windows you do have. That’s not a convenience issue; it’s a compliance one.
Our Main Denver Services
Most Denver homeowners call us for one of two things: fireplace work inside the firebox and chimney protection at the top. Here’s what each involves locally.
Fireplace Services in Denver
Denver’s older homes often have fireboxes sized for coal, not wood, which changes how a fire burns and how much heat actually reaches the room. We inspect the firebox, damper, smoke shelf, and hearth, then address what’s actually wrong: a warped damper, cracked firebrick, or a smoke chamber that’s pulling poorly. In converted coal-burning bungalows around Congress Park and Whittier, oversized flues paired with undersized wood fires are common, and they coat liners with glazed creosote faster than most owners expect. Our Fireplace Services in Denver page covers what we check, what it costs, and what can safely wait.
Chimney Cap & Crown in Denver
The crown is the concrete slab at the top of your chimney, and in Denver it takes a beating. Chinook-driven freeze-thaw cycles crack crowns within a few winters, and once water gets in, it works its way through mortar joints all the way down the stack. A cracked crown also invites rain, snow, and the occasional raccoon into the flue. We install and replace caps and crowns across Denver, including multi-flue caps for older duplexes in Baker and Berkeley. Read the specifics on our Chimney Cap & Crown in Denver page, including what a replacement crown costs.

BeforeAfterChimney Sweep in Denver
Chimney sweep in Denver runs $189 to $329 for a standard job, and the altitude changes what we find. At 5,280 feet, wood burns cooler and deposits creosote faster, especially in pre-WWII homes where coal fireboxes were converted to wood with liners sized for a much bigger fire. That combination, common in Congress Park and Whittier, produces glazed third-degree creosote at a rate that surprises owners who assumed annual cleaning would be enough. Glazed creosote is the hardest form to remove and the most likely to ignite; we remove it with rotary tools when a standard brush won’t cut it. Our full Chimney Sweep hub covers the process end to end.
Creosote Removal
Signs you need it
You’ll smell a sharp, campfire-like odor in the room even when the fireplace is cold, or you’ll see shiny, tar-like buildup on the flue walls when you shine a flashlight up from the firebox.
What it costs in Denver
Creosote removal in Denver ranges from $189 for light first-degree deposits to $450 for heavy glazed third-degree creosote requiring rotary tools.
How we do it
We run a camera up the flue to identify the creosote class, then use the appropriate tool, a nylon brush for first-degree, a wire brush or rotary whip for second and third-degree, and finish with a camera re-scan to confirm the flue is clear.
Level 2 Inspection
Signs you need it
You’ve had a chimney fire, you’re buying or selling the home, you’ve made a fuel change, or it’s been more than three years since anyone looked at the flue with a camera.
What it costs in Denver
A Level 2 inspection in Denver costs between $250 and $500, and it includes the camera scan, attic and crawlspace access checks, and a written report with photos.
How we do it
We run a camera from the firebox through the full flue length, inspect the accessible attic and crawlspace portions of the chimney structure, document everything with photos, and hand you a written report on the spot.
What Chimney Sweep Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Standard sweep with Level 1 inspection | $189 - $329 |
| Glazed third-degree creosote removal | $350 - $450 |
| Level 2 camera inspection | $250 - $500 |
How often should I have my chimney cleaned in Denver?
Every 30 to 60 burn fires, or at least once per heating season. Denver’s altitude accelerates creosote buildup, so if you burn weekly from October through March, schedule a sweep each fall.
Is chimney cleaning messy?
No, when it’s done with a HEPA-filtered vacuum and drop cloths. We run the vac from the firebox while we sweep from the top or bottom, and the room is left cleaner than we found it.
Chimney Repair in Denver
Chimney repair in Denver is driven by one word: water. The freeze-thaw cycle crosses the freezing threshold roughly 60 times per year, and every cycle opens mortar joints a little further, letting water into the brick, where it refreezes and spalls the faces off. Homes in Capitol Hill, Sunnyside, and Baker, most of them built before 1950 with original masonry, take the worst of it. A repair we handle correctly now costs a fraction of what a full rebuild costs three winters later. Our Chimney Repair hub walks through every repair type we do.
Mortar Repointing
Signs you need it
You can see gaps or missing mortar between bricks, or you find sandy grit on the hearth or at the base of the chimney after a storm.
What it costs in Denver
Mortar repointing in Denver runs $900 to $2,500 depending on the height of the stack and how many joints have opened.
How we do it
We grind out deteriorated mortar to a consistent depth, mix a color-matched mortar, tuck and compress it into the joints, then brush the surface clean so the repair blends with the existing brick.
Chimney Waterproofing
Signs you need it
You see dark, damp staining on the chimney brick, white efflorescence deposits on the masonry, or water pooling inside the firebox after rain.
What it costs in Denver
Chimney waterproofing in Denver typically costs $300 to $800, with the higher end covering taller stacks and multi-flue chimneys.
How we do it
We repair any damaged mortar first, then spray the masonry with a vapor-permeable waterproofing treatment that keeps water out while letting moisture that’s already inside escape.
What Chimney Repair Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Mortar repointing | $900 - $2,500 |
| Chimney waterproofing | $300 - $800 |
| Spalling brick repair | $150 - $450 |
Can you repair a chimney in winter in Denver?
Yes, with cold-weather mortar and waterproofing rated for low-temperature application. However, freeze-thaw cycles are hardest in January and February, so we schedule the most weather-dependent repointing work between March and November when possible.
How long does chimney repair last in Denver’s climate?
Properly repointed mortar and a good waterproofing treatment typically last 15 to 20 years. Denver’s freeze-thaw cycling shortens that window compared to milder climates, which is why we recommend a camera inspection every few years.
Chimney Liner & Rebuild in Denver
Chimney liner and rebuild work in Denver often traces back to the same root: pre-1950s homes were built with clay tile liners sized for coal fires, and those liners are now cracked, oversized, or both. Once a liner cracks, flue gases and heat reach the surrounding masonry, and in a city with Denver’s freeze-thaw cycling, that accelerates structural damage from the inside out. We replace liners with properly sized stainless steel, using materials from DuraFlex and Olympia Chimney, and we rebuild stacks when the masonry itself has gone too far. Our Chimney Liner & Rebuild hub covers the full scope.
Liner Replacement
Signs you need it
Your camera inspection shows cracked or missing clay tile sections, or you’re seeing pieces of tile in the firebox after a storm.
What it costs in Denver
Liner replacement in Denver ranges from $3,500 to $6,000 for a standard single-flue home, with the higher end covering taller stacks and more complex installations.
How we do it
We measure the flue, select the correct diameter stainless steel liner from DuraFlex or Olympia Chimney, insulate it, and pull it through the existing flue from the top down, then connect it to the appliance and seal the crown.
Full Chimney Rebuild
Signs you need it
You see leaning or visibly bowing masonry, bricks crumbling to the touch, or a structural report from an inspector recommending rebuild rather than repair.
What it costs in Denver
A full chimney rebuild in Denver runs $7,000 to $15,000 from the roofline up, depending on height, brick type, and whether the flue liner is replaced at the same time.
How we do it
We take the stack down to sound masonry, rebuild with new brick and color-matched mortar, install a new flue liner if needed, and pour a new crown with a proper drip edge.
What Chimney Liner & Rebuild Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Liner replacement (standard single-flue) | $3,500 - $6,000 |
| Partial rebuild (above roofline) | $4,000 - $7,000 |
| Full chimney rebuild | $7,000 - $15,000 |
Do I really need a new liner, or can the old one be patched?
A cracked clay tile liner cannot be safely patched. The crack lets heat and gases reach the masonry, and in Denver that’s a fire hazard and a structural problem. Liner replacement is the correct fix, and it’s less expensive than a rebuild later.
How long does a liner replacement take in Denver?
Most single-flue liner replacements take one full day, including the camera re-scan and written documentation. A full rebuild takes two to four days depending on height and weather windows.
Brands We Service in Denver
We work on and install liners and caps from DuraFlex, Olympia Chimney, Gelco, and Copperfield. Our Denver crew stocks the most common liner diameters and cap sizes locally, so most liners and caps go in within a week of the written quote. See our brands for the full list.

What pushes a Denver price toward the top of these ranges is altitude and access. A three-story stack in Capitol Hill with steep roof pitch takes longer to work on than a single-story ranch in Harvey Park. Glazed creosote, common here because of cooler burns at elevation, requires rotary tools and more time. Every job gets a written price and written scope before work starts, no exceptions.

FAQs About Chimney Cleaning in Denver
Sweeps and inspections are typically scheduled within 5 to 7 days across the Denver metro. Liner replacements and rebuilds are quoted in writing first, then scheduled once you approve; those run one to three weeks out depending on weather and materials.
Routine cleaning and inspections do not require a permit in Denver. Structural work like a full rebuild or liner replacement may, depending on the scope and whether the work changes the flue configuration. We handle the permitting conversation during the quote process and put everything in writing.
The Regional Air Quality Council issues mandatory curtailment days during winter inversions, and burning is legally restricted on those days. Your best move is a clean flue and an efficient fire: call (980) 580-8641 to get the flue inspected before burning season starts, and check the RAQC’s daily status before you light a fire.
