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.

Chimney cap and crown work in Denver runs $340-$1,800 depending on whether we’re sealing hairline cracks or replacing a spalled crown after a hard freeze. At 5,280 feet with Chinook winds that swing temperatures 40°F in hours, Denver’s brick and mortar take a beating that lower-altitude cities simply don’t see. We inspect the crown and cap on every visit with a camera down the flue, and we put the price in writing before any work starts. Call (720) 439-4666 for a free estimate.
Why Denver Homes Are Different
Denver’s thinner air means incomplete combustion and faster creosote buildup than at sea level. The city’s Air Pollution Control Division enforces no-burn days, so homeowners skip weeks then burn heavily when permitted, converting soft creosote into glazed Stage 3 that standard brushes won’t touch. In Highlands, Baker, and Curtis Park, 1890s-1940s brick Victorians have original unrelined masonry chimneys sized for coal, not modern appliances. Postwar ranches in Park Hill and Harvey Park harbor zero-clearance metal fireplaces past their 25-year service life. The Front Range’s freeze-thaw cycling and dry, erosive climate chew through mortar and crowns faster than humid markets. Capitol Hill chimneys adapted from coal boilers to gas without relining create chronic draft failures and condensate damage we flag on first inspection.
Our Main Denver Services
Most Denver calls start with a sweep and inspection, then branch to cap, crown, liner, or repair work once we show the homeowner what the camera found.
Chimney Cleaning & Sweep in Denver
We run a rotary system with poly or wire brushes matched to your flue liner type, vacuum-sealed for dust control. In Denver, Stage 3 creosote from altitude-induced incomplete combustion often requires mechanical treatment before the sweep. Every job includes NFPA 211 Level 2 camera inspection and a documented photo record under Haven Standard Clause 4. Chimney Cleaning & Sweep in Denver

AfterChimney Cap & Crown in Denver
Denver’s semi-arid climate and aggressive freeze-thaw cycling dry out and erode mortar faster than humid markets, making annual crown and cap inspection more clinically necessary here. We replace or repair crowns and caps across the metro, from the original soft-brick chimneys of Curtis Park to the suburban prefab units in Montbello, always with a written price before work starts and a photo record after. Chimney Cap & Crown work is our most frequent follow-up service after a Level 2 inspection finds water intrusion or spalling.
Crown Repair
Signs you need it
Visible cracks, pooling water, or spalling concrete on the crown surface that lets moisture into the chimney stack.
What it costs in Denver
Crown repair runs $340-$680 for crack sealing and resurfacing, while full crown replacement ranges $850-$1,800 depending on chimney width and access.
How we do it
We grind out cracks, apply a bonding agent, and pour new high-strength concrete with a proper drip edge and slope for water runoff.
Crown Coating
Signs you need it
Hairline cracks under 1/8 inch with no structural spalling, typically found on crowns less than 15 years old in Denver’s dry climate.
What it costs in Denver
Crown coating with a flexible elastomeric sealant runs $340-$550 for standard residential chimneys.
How we do it
We clean and prime the crown surface, then brush or spray two coats of UV-stable elastomeric coating rated for freeze-thaw cycling.
What Chimney Cap & Crown Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Crown coating (elastomeric) | $340 - $550 |
| Crown repair / resurfacing | $340 - $680 |
| Full crown replacement | $850 - $1,800 |
How long does a chimney crown last in Denver?
A properly poured concrete crown with overhanging drip edge lasts 15-25 years in Denver’s climate, but crowns without adequate slope or sealant often fail in 8-12 years due to freeze-thaw cycling. Annual inspection catches early deterioration before water reaches the flue.
Can a cracked crown wait until next season?
Hairline cracks can be coated if caught early, but open cracks that pool water will expand through winter freeze-thaw and accelerate spalling. We document the crack width and depth with photos so you can see whether the repair is preventive or urgent.
Chimney Liner & Rebuild in Denver
Capitol Hill and Curtis Park chimneys converted from coal to gas or wood without relining have oversized flues that cause chronic draft problems and corrosive condensate damage. We install stainless steel and flexible liners sized precisely to the appliance, with a written price before work starts and a documented photo record under Haven Standard Clause 4. Chimney Liner & Rebuild work in Denver also addresses heat-warped zero-clearance fireboxes in postwar ranches that have exceeded their safe service life.
Stainless Steel Liner
Signs you need it
Cracked clay tiles, condensate stains on the smoke chamber walls, or draft complaints in a chimney serving a wood stove or insert.
What it costs in Denver
Stainless steel liner installation runs $1,200-$2,800 depending on flue height, diameter, and whether the chimney needs a new top plate.
How we do it
We measure the flue with a video scan, drop a properly sized 316Ti stainless liner, insulate with ceramic blanket where required by code, and seal the top with a custom plate.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning stack, or mortar loss deep enough to expose the flue liner to weather.
What it costs in Denver
Partial rebuild of the stack above the roofline runs $1,500-$3,500 depending on height, scaffolding needs, and matching historic brick.
How we do it
We dismantle to sound masonry, salvage matching brick where possible, and rebuild with Type N or Type S mortar rated for Denver’s freeze-thaw exposure.
What Chimney Liner & Rebuild Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Stainless steel liner (installed) | $1,200 - $2,800 |
| Flexible liner for gas appliance | $900 - $1,800 |
| Partial rebuild (above roofline) | $1,500 - $3,500 |
Do I need a liner if my chimney was built for a wood stove?
Original masonry chimneys in Denver’s 1890s-1940s housing stock were sized for coal or open fireplaces, not modern stoves. An oversized flue cools smoke too quickly, causing creosote buildup and poor draft. We measure with a camera scan and size the liner to the appliance’s listed requirements.
How long does a stainless steel liner last?
316Ti stainless steel liners carry a lifetime warranty when properly installed and maintained with annual sweeping. We document the installation with photos and a written warranty under Haven Standard Clause 1.

FAQs About Chimney Cleaning in Denver
Most chimney repairs and liner installations require a Denver building permit; cap and sweep work typically do not. We handle permit applications as part of our scope for rebuild and liner jobs, and we note permit status on your written estimate.
Denver’s Air Pollution Control Division calls no-burn days during high particulate events. The start-stop burning pattern this creates produces harder, more glazed creosote that needs professional removal. We factor burn history into our sweep approach and document creosote class in your photo record.
Standard inspections and sweeps are typically scheduled within 5-7 days during peak season (September-January), and within 2-3 days in off-peak months. Emergency inspections for suspected blockages or post-storm damage are prioritized. Call (720) 439-4666 to check current availability.
