Trusted Chimney Cleaning for Denver Homeowners
Denver Chimney Cleaning typically costs between $180 and $420 for a standard inspection and sweeping, with most homes falling in the $220 to $320 range depending on creosote buildup and chimney height. The job usually takes 60 to 90 minutes. We’ve been serving Denver homeowners since 1998, and every visit includes photographic evidence of what we found before and after the sweep.
Denver’s elevation and cold winters mean your fireplace works harder than almost anywhere else in the country. The combination of pine, aspen, and occasional cottonwood burned at 5,280 feet produces a dense, sticky creosote that coats the flue liner fast. We’ve cleaned chimneys in Washington Park, Cherry Creek, Park Hill, and Berkeley where the buildup was thick enough to require specialized glazing tools. A dirty chimney isn’t a maintenance footnote here. It’s the leading cause of chimney fires in the metro area, and the fix is a phone call to (970) 725-6025.
What Our Chimney Cleaning Service Includes
Full Chimney Sweeping
A full sweep removes creosote, soot, and debris from the flue liner, smoke chamber, damper, and firebox. Denver chimneys accumulate creosote differently than sea-level homes because the thinner air at altitude changes combustion temperature, which accelerates condensation inside the flue. We use rotary wire brushes and HEPA-filtered vacuums to contain every particle inside your home, with drop cloths and shoe covers standard on every job.
You need a sweep at least once per burning season, and more often if you burn pine or firewood that hasn’t fully seasoned. The National Fire Protection Association recommends an inspection and cleaning when creosote reaches 1/8 inch thickness. Under the Haven Standard, we photograph the creosote level with a measurement reference in the frame, so you see exactly what we saw. The price is in writing before we start, and the photos go into your report before we leave.
Chimney Inspection
A chimney inspection checks the structural integrity of the flue, crown, cap, mortar joints, and firebox. We perform visual inspections with a video camera that reaches the full height of the flue, documenting cracks, spalling, animal entry points, and deteriorated mortar. In Denver, freeze-thaw cycles stress brick chimneys more than most climates because temperatures swing across the freezing line dozens of times each winter.
We recommend a camera inspection with every sweep, or at minimum once per year before the burning season starts. What the camera finds determines whether your chimney needs a simple cleaning or masonry repair. A hairline crack that looks cosmetic on a visual check can be a chimney fire risk when it opens slightly during the first hard freeze. Our technicians document every finding photographically and explain what needs attention now versus what can wait.
Chimney Cap Installation and Repair
A chimney cap keeps rain, snow, birds, squirrels, and leaves out of your flue. Denver’s afternoon thunderstorms and heavy spring snows push water into uncapped chimneys, which erodes the flue liner from the inside and causes premature deterioration. We install stainless steel and copper caps sized to your flue dimensions, and repair or replace damaged caps during the same visit.
Most Denver homes built before 1990 either never had a cap or lost the original one to one of our famous wind events. The cost of a cap is small compared to the masonry repair bill from years of uncontrolled water entry. Every cap we install is photographed in place, and the price was agreed before we ordered or installed anything.
Fireplace and Stove Cleaning
Fireplace and stove cleaning covers the firebox, ash removal, glass door cleaning, and interior chamber surfaces. Wood-burning fireplaces and stoves in Denver collect ash, fine dust, and creosote residue that impedes airflow and reduces efficiency. We remove the old ash, clean the firebrick surfaces, and restore the glass to clear using products formulated for ceramic fireplace glass.
Gas fireplaces need this service less often for creosote, but more often for dust, pet hair, and soot accumulation on the logs and burner assembly. Denver’s dry winter air means dust moves through homes at higher rates than humid markets, and that dust settles into gas log sets where it can cause ignition problems. We clean gas fireplace media, check the thermocouple and thermopile, and photograph the before and after state of the burner.
Smoke Chamber Cleaning
The smoke chamber is the area above the firebox where smoke compresses before entering the flue. This is the most overlooked part of chimney maintenance, and in Denver it’s where we find the heaviest glazed creosote deposits on older homes in neighborhoods like Congress Park and Montclair. Glazed creosote in the smoke chamber is a leading cause of chimney fires because it sits directly above the hottest part of the fire.
Our technicians use chain flails and chemical treatments to break up glazed creosote, then sweep and vacuum the chamber to bare surface. The process takes an additional 20 to 30 minutes beyond a standard sweep, and we document the before and after condition with photos and a written thickness measurement. If creosote has glazed to the point where mechanical removal risk damaging the masonry, we’ll recommend a chemical treatment and schedule the follow-up before the season starts.
Dryer Vent Cleaning
Many Denver homeowners don’t connect dryer vent cleaning to chimney safety, but the two systems share the same principle: airflow obstruction creates fire risk. Lint builds up in dryer vents over time, and in Denver’s dry winter air, that lint is tinder-dry and ready to ignite from one spark of static or heat. We use rotary brush systems that reach the full length of the vent run and remove the entire blockage.
A clogged dryer vent shows symptoms before it becomes dangerous: clothes take longer to dry, the dryer exterior feels hot, and the laundry room smells musty when the dryer runs. We recommend dryer vent cleaning annually, especially in Denver homes where long vent runs through finished basements and crawlspaces make access difficult. The same photographic evidence standard applies, and the price was in writing before we started.

Brands We Service for Chimney Cleaning
We work on chimneys and fireplaces connected to every major brand, including Craftsman fireplaces and accessories. Craftsman’s masonry fireplace tools and prefabricated firebox units are common in Denver’s mid-century and split-level homes, and our technicians understand the specific combustion characteristics and clearance requirements of those installations. We’ve cleaned hundreds of Craftsman-equipped fireplaces across the Denver metro and stock the replacement parts those systems need most often: damper plates, refractory panels, and cap assemblies.
We also regularly service Chimney brand and Superior brand prefabricated fireplace systems found in Denver’s newer construction from the 1990s forward in neighborhoods like Stapleton and Lowry. Prefabricated fireplaces have different flue lining requirements and inspection protocols than masonry chimneys, and our team knows the difference. Whether you have a Craftsman, a Superior, or any other make, the Haven Standard is identical: price in writing, photos in the report, and the license number on the page before anyone enters your home.
Before
AfterSigns You Need Chimney Cleaning Right Now
- Visible creosote buildup on the damper or firebox walls. Creosote is the black or brown residue that clings to everything above your fire. If you can scrape it with a fireplace tool and it’s thicker than an eighth of an inch, the flue is carrying more of the same, and that’s a fire hazard waiting for one hot fire to ignite it.
- Smoke enters the room instead of going up the flue. A draft problem in Denver is usually caused by creosote restriction, an animal nest, or a closed or broken damper. Smoke backing into your living room isn’t just annoying, it’s carbon monoxide entering your home, and it needs a professional diagnostic immediately.
- You smell a campfire-like odor when the fireplace isn’t in use. That odor is creosote off-gassing inside your home, which usually means there’s enough buildup that it’s releasing volatile compounds. In Denver’s frequent barometric pressure swings, this odor gets worse before and after snowstorms because pressure differentials pull air down the chimney.
- Animals or debris have been in or around the chimney cap. Denver squirrels, raccoons, and chimney swifts all try to nest in chimneys during the spring and fall. A nest blocks airflow and a dead animal creates an odor that gets worse with every burning cycle. We remove nests and install caps that prevent recurrence.
- It’s been more than one year since the last cleaning. The National Fire Protection Association’s minimum standard is an annual inspection for any wood-burning chimney, and Denver’s altitude and fuel types push creosote production faster than most markets. If you can’t remember the last cleaning, that’s your answer.
Our Chimney Cleaning Process - Step by Step
Step 1: Visual and Camera Inspection
We start by examining the firebox, damper, smoke chamber, and chimney crown from the ground and from the roof. Then we run a video camera up the flue to document creosote thickness, liner condition, and any obstruction. Every finding is photographed, and we review those photos with you before any work begins.
Step 2: Work Area Protection
Before the first brush touches the flue, we seal the fireplace opening and lay drop cloths from your entry door to the hearth. Our HEPA-filtered vacuums run continuously during the sweep to maintain negative pressure and keep soot from entering your living space. Shoe covers are worn throughout, and we protect your floors and furniture as if they were our own.
Step 3: Mechanical and Rotary Sweeping
We use rotary wire brushes sized to your flue dimensions to dislodge creosote and soot from the liner walls. For glazed creosote, we apply specialized chemical treatments and use chain flails to break through the hardened surface without damaging the masonry. The smoke chamber gets dedicated attention because this is where Denver homes accumulate the heaviest deposits.
Step 4: Debris Removal and Final Inspection
After sweeping, we vacuum the entire system from top to bottom, remove the firebox debris, and run the camera again to verify the flue is clean to the liner surface. We check the damper operation, test the draft, and confirm the chimney cap is seated correctly. You see the before and after photos side by side.
Step 5: Report and Recommendation
You receive a written report with photos, measurements, and any recommendations for repairs or maintenance items. If we found something that needs attention, we explain what it is, what it costs, and when it needs to be done. There is no upsell at the door, and the price for everything we recommend is on the page before you decide.
How Much Does Chimney Cleaning Cost in Denver?
A standard chimney cleaning in Denver runs $220 to $320 for most homes with a single flue and accessible roof. Homes with steep roofs, multiple flues, or heavy glazed creosote can push the total to $420 or more because the additional labor and chemical treatment are billed at standard rates. Chimney inspections with video camera documentation typically add $75 to $150 when done as a standalone service, and chimney cap installation ranges from $150 to $450 depending on flue size and material.
| Service | Typical Price Range |
|---|---|
| Standard chimney sweep (single flue) | $220-$320 |
| Video camera inspection | $75-$150 |
| Chimney cap installation | $150-$450 |
| Smoke chamber cleaning (add-on) | $80-$160 |
| Dryer vent cleaning | $90-$180 |
What affects the price most is creosote condition. Light soot is fast to remove. Glazed creosote takes longer and requires chemical products. Roof access matters too: steep pitches on Denver neighborhoods like University Hills and Harvey Park require additional safety equipment and a second technician on some jobs. The Haven Standard requires that your price is in writing before any work begins, and that the person who arrives has a license number you can verify before they cross the threshold. A free estimate is always available by phone, and the number you call is answered by a live person, not an automated system. Call (970) 725-6025 for an exact quote based on your chimney’s condition.

Frequently Asked Questions - Chimney Cleaning in Denver
Chimney cleaning is the removal of creosote, soot, and debris from the flue liner, smoke chamber, damper, and firebox. In Denver, this is an annual maintenance requirement because burning wood at 5,280 feet creates creosote faster than at sea level, and a dirty chimney is the top cause of chimney fires in the metro. A clean chimney drafts better, burns more efficiently, and reduces carbon monoxide risk during the burning season.
A standard chimney sweep and inspection takes 60 to 90 minutes for a single flue on an accessible roof. Glazed creosote removal, smoke chamber cleaning, or a camera inspection adds 20 to 30 minutes per component. We work efficiently and cleanly, with the entire work area protected and vacuumed throughout.
The typical cost is $220 to $320 for a standard sweep, with video inspection adding $75 to $150, cap installation at $150 to $450, and smoke chamber work at $80 to $160 when added to a sweep. The final price depends on creosote condition and roof access. Under the Haven Standard, your price is in writing before any work begins, so you know exactly what you’re paying before we start.
