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 Boulder, CO
Chimney cap and crown work in Boulder runs $450-$2,800 depending on whether we’re installing a new cap, rebuilding a crown, or addressing Chinook wind damage that’s left your flue exposed. The 100 mph gusts coming off the Flatirons destroy poorly secured caps and crack mortar crowns through rapid freeze-thaw cycling, which is why most calls we get from Table Mesa and Martin Acres start with water stains on the ceiling or birds in the flue. Call (970) 598-0453 and we’ll send a camera down, show you what the wind and elevation have done, and give you a written price before any work starts.
Why Boulder Homes Are Different
Boulder sits at 5,430 feet with the Flatirons funnelling Chinook winds that regularly exceed 100 mph. That combination tears off chimney caps and creates pressure differentials that push smoke back into living rooms on days when the chimney is structurally sound. The city’s strict growth-management policies have preserved thousands of mid-century masonry fireplaces in neighborhoods like Table Mesa, Martin Acres, and Gunbarrel, many built without liners and never updated. Mapleton Hill and Whittier hold late-Victorian and Craftsman rubble-stone chimneys that need careful camera inspection before any high-output use.
The thinner air here means cooler combustion and faster creosote accumulation than at Denver’s elevation. When Boulder County calls a wood-burning action day, residents who burn infrequently tend to overload their fires, accelerating liner deterioration. Freeze-thaw swings amplified by Chinook temperature spikes of 40°F in hours destroy mortar crowns between annual visits.
Our Main Boulder Services
Most Boulder homeowners who call us need one of these three services, each with its own local page and pricing.
Chimney Cleaning & Sweep in Boulder
We clean and inspect masonry and factory-built systems in Boulder with an NFPA 211 Level 2 camera scan included every time.

BeforeAfterChimney Cap & Crown in Boulder
Cap and crown work is what we get called for after every major Chinook event in Boulder. The wind gusts that tear through the Flatirons foothills corridor rip off lightweight caps and hammer crowns with debris, while the 40°F temperature swings in a single day open hairline cracks in mortar that let water straight into the chase. In neighborhoods like Table Mesa and Gunbarrel, we’re often working on mid-century chimneys that have never had a proper cap installed, leaving the flue open to water, animals, and the pressure differentials that cause backdrafting. Chimney Cap & Crown work here requires understanding both the wind dynamics and the housing stock, or you’ll be replacing the same cap every other winter.
Cap Replacement
Signs you need it
Your cap is missing, visibly bent, or you’ve found debris or bird nests in the flue after a wind event.
What it costs in Boulder
Cap replacement in Boulder typically runs $450-$850 for a standard single-flue stainless unit, with wind-directional and custom sizes running higher.
How we do it
We measure the flue opening, photograph the existing flue condition, install a cap sized to local wind load with proper fastening, and document the finished work.
Crown Repair
Signs you need it
You see cracks in the mortar crown, water staining on the ceiling near the chimney, or pieces of crown material in the fireplace or on the roof.
What it costs in Boulder
Crown repair in Boulder ranges from $650 for crack sealing and resurfacing to $1,800-$2,800 for full crown rebuilds on larger or severely deteriorated chimneys.
How we do it
We grind out damaged material, form and pour new crown concrete with proper overhang and drip edge, and apply a waterproofing seal rated for high-elevation UV exposure.
What Chimney Cap & Crown Costs in Boulder
| Item | Typical range in Boulder |
|---|---|
| Standard cap replacement | $450 - $850 |
| Crown crack repair / coating | $650 - $1,200 |
| Full crown rebuild | $1,800 - $2,800 |
Can Chinook winds really rip a chimney cap off?
Yes, we’ve replaced caps after 100 mph gusts in Table Mesa and Martin Acres that tore off poorly secured units and dented heavier ones. Wind-directional caps with proper through-bolt fastening solve this.
How do I know if my crown is cracked or just dirty?
We camera-scan from the top down during every cap and crown estimate; cracks visible to the camera that hold moisture are documented in your photo record with a written repair scope and price.
Chimney Liner & Rebuild in Boulder
Liner and rebuild work in Boulder is driven by two realities: the unlined mid-century masonry stock in Gunbarrel and Martin Acres, and the accelerated deterioration that comes from cooler, less complete combustion at 5,430 feet. Many fireplaces here were built without liners or with clay liners that have cracked after decades of thermal cycling. When we find a compromised liner, we explain exactly what the camera shows, quote a stainless or flexible liner system in writing, and install to NFPA 211 standards with materials from Chimney Liner & Rebuild suppliers like DuraFlex and Olympia Chimney.
Stainless Steel Liner
Signs you need it
The camera shows cracked clay tiles, gaps between flue sections, or Class III creosote buildup that has adhered to damaged liner surfaces.
What it costs in Boulder
Stainless steel liner installation in Boulder typically runs $2,500-$4,500 depending on flue height, diameter, and whether the smoke chamber needs parging.
How we do it
We measure the flue with a video scan, drop a properly sized DuraFlex or Olympia Chimney stainless liner with insulation where required, and connect to a new top plate and cap.
Partial Rebuild
Signs you need it
Spalling brick, deteriorated mortar joints above the roofline, or a leaning chimney stack that the camera shows is structurally separating from the house.
What it costs in Boulder
Partial rebuilds in Boulder range from $3,500-$7,500 for above-roof work, with full rebuilds starting higher depending on height and access.
How we do it
We scaffold to height, dismantle damaged courses to sound masonry, rebuild with matching brick and proper crown and flashing integration, and photograph every stage.
What Chimney Liner & Rebuild Costs in Boulder
| Item | Typical range in Boulder |
|---|---|
| Stainless steel liner installation | $2,500 - $4,500 |
| Flexible liner (factory-built chase) | $2,200 - $3,800 |
| Partial rebuild (above roofline) | $3,500 - $7,500 |
Do I really need a liner if my chimney has worked fine for 50 years?
Unlined masonry in Boulder’s mid-century housing was common but is not safe for modern high-output fires; the NFPA 211 Level 2 camera inspection shows exactly what condition your flue is in and whether a liner is required.
Can a liner fix a chimney that backdrafts on windy days?
A liner improves draft but cannot overcome extreme Chinook pressure differentials; we diagnose whether the issue is flue sizing, liner condition, or wind dynamics, and specify a wind-directional cap if that’s the actual problem.
