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.

A Level 2 chimney inspection and cleaning in Denver typically costs $199-$289 and includes a camera-scan of the flue, written price before work starts, and a documented photo record. We’re Level Two Chimney Co., and our crews coordinate from our Denver office to serve homeowners across the metro. Call (720) 674-7312 for a written estimate you can hold in your hand before anyone picks up a brush.
Denver’s altitude, freeze-thaw cycles, and wood-burning curtailment patterns create chimney problems you won’t find in lower-elevation cities. Our Chimney Cap & Crown and Chimney Liner & Rebuild work addresses the specific failures we document here every week.
Why Denver Homes Are Different
At 5,280 feet, Denver’s air holds roughly 17% less oxygen than at sea level. Wood fires burn less completely and deposit more creosote per cord than in coastal cities. The Denver Metro Area’s formal wood-burning curtailment program compounds this: fireplaces sit cold on mandated “Red Air Quality” no-burn days, then burn heavily on every permitted “Green” day. That use-dormancy cycle hardens creosote into glazed, third-degree deposits that standard annual schedules miss.
Denver’s housing stock splits into two vulnerable eras. Capitol Hill, Baker, Highlands, Curtis Park, and Potter-Lawson hold 1890s-1930s Victorians and Craftsman bungalows, many with original unlined brick flues or cracked clay-tile liners that predate modern NFPA 211 clearance rules. The 1950s-70s ranch buildout across Harvey Park, Barnum, and Westwood added masonry fireplaces now 50-70 years old with failing mortar crowns and spalling corbeled brick caps.
Front Range temperature swings drive the structural damage. A January week in Denver can cycle from −10°F nights to 55°F afternoons, fracturing mortar joints and spalling brick faster than in stable climates. Average 57 inches of wet, heavy snowfall accumulates on crowns, then chinook-wind warm spells push meltwater into hairline cracks before the next hard freeze. We see the damage start at the top and work down.
Our Main Denver Services
Denver homeowners call us most often for these three services:
Chimney Cleaning & Sweep in Denver
We brush, vacuum, and camera-scan the flue to NFPA 211 Level 2, documenting creosote class and liner condition with photos. In Denver, we regularly find glazed deposits from altitude-impaired combustion and curtailment cycling in homes near Cheesman Park and Capitol Hill. Chimney Cleaning & Sweep in Denver includes the written price before work starts and a photo record under Haven Standard Clause 4.
Chimney Repair in Denver
We rebuild spalled crowns, repoint mortar joints fractured by freeze-thaw, and replace deteriorated flashing. Denver’s chinook-melt cycles destroy crown integrity from the top down, especially on 1960s-70s ranch chimneys in southwest neighborhoods. Chimney Repair in Denver comes with a written scope, written warranty, and the 365-Day Done Right Promise.
Fireplace Services in Denver
We service factory-built and masonry fireplaces, including damper repair, smoke chamber parging, and firebox rebuilds. Denver’s altitude affects draft calculations, and we measure actual performance rather than assuming sea-level specs. Fireplace Services in Denver includes camera documentation and a written report on every visit.

Before
AfterChimney Cap & Crown in Denver
Denver’s combination of wet, heavy snow and rapid chinook-warmth cycles destroys chimney caps and crowns faster than in any metro we serve. The 50-70 year old masonry on Harvey Park and Barnum ranch homes was never designed for this thermal stress, and original corbeled brick caps have no defense against meltwater intrusion. Our Chimney Cap & Crown work starts with a camera inspection to document whether the damage is cosmetic or structural before we quote a dollar.
Cap Replacement
Signs you need it
Rust streaks down the flue tile, visible mesh deterioration, or a cap that rattles loose after every wind event along the Front Range.
What it costs in Denver
Cap replacement runs $180-$340 for standard single-flue stainless models, with multi-flue custom caps ranging $340-$620 depending on flue count and mesh specification.
How we do it
We measure the flue tile and crown footprint, fabricate or source the cap from Olympia Chimney or Gelco through our Haven buying network, and secure it with masonry screws and high-temp sealant that survives Denver’s freeze-thaw.
Crown Repair
Signs you need it
Hairline cracks widening after winter, concrete spalling that exposes aggregate, or pooling water on the crown surface after snowmelt.
What it costs in Denver
Crown repair with poured concrete or CrownCoat application ranges $280-$480; full crown rebuild on deteriorated 1960s-70s ranch chimneys runs $680-$1,200.
How we do it
We grind out cracked material to sound substrate, form and pour new concrete with proper slope and drip edge, or apply flexible CrownCoat for minor cracking, then document the repair with photos under Haven Standard Clause 4.
What Chimney Cap & Crown Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Cap replacement (single-flue) | $180-$340 |
| Multi-flue custom cap | $340-$620 |
| Crown repair / coating | $280-$480 |
| Full crown rebuild | $680-$1,200 |
Do I need a new cap or just a repair?
If the mesh is intact and the base flange isn’t rusted through, we can often reseat and seal the existing cap. We camera-inspect to confirm before quoting.
How long does a crown repair last in Denver’s climate?
A properly poured concrete crown with correct slope and overhang lasts 15-20 years even in Front Range freeze-thaw; coatings need refresh at 5-8 years. We warranty our crown work for 365 days under the Done Right Promise.
Chimney Liner & Rebuild in Denver
Denver’s 1890s-1930s housing stock in Capitol Hill, Baker, and Curtis Park contains thousands of unlined brick flues and fractured clay-tile liners that predate NFPA 211. At altitude, incomplete combustion produces more acidic condensate that accelerates liner deterioration, and the corrosive byproducts eat exposed mortar joints. Our Chimney Liner & Rebuild work installs stainless or flexible liners rated for Denver’s specific venting demands, with camera documentation before and after.
Stainless Steel Liner
Signs you need it
Flue tiles with visible cracks or missing pieces on camera inspection, or a chimney that fails NFPA 211 Level 2 due to gaps exposing combustible framing.
What it costs in Denver
Stainless steel liner installation ranges $1,800-$3,400 for a standard fireplace flue, with DuraFlex or Olympia Chimney materials sized to your appliance BTU rating and Denver’s altitude-adjusted draft.
How we do it
We drop a video camera first to map flue condition and obstructions, then install a continuous stainless liner with proper top plate and bottom connector, insulating when required by code and documenting every joint with photos.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, a leaning stack, or mortar joints you can probe with a screwdriver after winter freeze-thaw cycles.
What it costs in Denver
Partial rebuild of the upper chimney structure runs $1,200-$2,800 depending on courses replaced, scaffolding needs, and whether the crown is salvageable.
How we do it
We dismantle to sound masonry below the roofline, replace spalled brick with matching units, repoint with Type N mortar rated for Denver’s thermal cycling, and pour a new sloped crown before camera-documenting the completed stack.
What Chimney Liner & Rebuild Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Stainless steel liner | $1,800-$3,400 |
| Flexible liner (gas appliance) | $1,400-$2,600 |
| Partial rebuild (upper stack) | $1,200-$2,800 |
| Full chimney rebuild | $4,500-$8,500 |
Can I just use my unlined brick flue?
Unlined brick flues in Denver’s pre-1940 housing fail modern NFPA 211 clearance requirements and accelerate creosote buildup at altitude. We won’t certify an unlined flue for wood-burning use; a stainless liner is the standard repair.
Does a liner installation require a permit in Denver?
Most liner replacements and rebuilds require a Denver building permit; we pull it as part of our scope and schedule inspection. The permit cost is itemized in your written price before work starts.

FAQs About Chimney Cleaning in Denver
Denver’s 17% lower oxygen content produces more incomplete combustion and heavier creosote deposits per cord burned. We adjust our inspection criteria and cleaning frequency recommendations based on actual flue conditions, not a generic annual calendar.
Most liner installations, rebuilds, and structural repairs require a Denver building permit; we handle the application and inspection scheduling. Routine Level 2 sweeps and cap replacements typically do not.
We typically book sweep appointments within 3-5 business days during peak season, and rebuild or liner work within 5-7 days to allow permit processing. Call (720) 674-7312 for current availability.
