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.

AfterFast, Reliable Fireplace Services Across Boulder
Fireplace service in Boulder runs $180-$450 depending on whether you need a standard gas fireplace tune-up or full firebox repair on an unlined mid-century chimney. Our crews are dispatched from the Denver metro office and typically reach Boulder homes within 45-60 minutes, with same-week booking available most of the year. Call (970) 598-0453 for a written estimate before any work starts.
We’ve worked on chimneys from Mapleton Hill Victorians to the 1960s tract homes in Table Mesa and Martin Acres, and the problems we find are rarely what the homeowner expected. That’s why every Fireplace Services visit starts with a camera down the flue and ends with photos you can see, a written price you agreed to, and a 365-Day Done Right Promise stamped on the invoice.

Why Emberly Chimney Cleaners Boulder Is Boulder’s Preferred Fireplace Services Company
Emberly Chimney Cleaners has completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented photo record when it was done. In Boulder specifically, we’ve built our reputation on not upselling full liner replacements when a wind-directional cap or crown repair is the actual fix.
Our reviews from Boulder customers consistently mention the camera footage - being able to watch the inspection live on screen, then receiving the photo archive afterward. Clause 4 of the Haven Standard requires this documentation on every job, and we’ve operated that way since founding.
Response time to Boulder averages under an hour from dispatch. Scheduling is coordinated from our Denver office, with background-checked, uniformed technicians who text when they’re en route. License information is displayed on every page, and a named tech is assigned to your job, not a rotating subcontractor.
What separates us in this market is knowing Boulder’s specific failure modes: the Chinook wind dynamics that push smoke back down clean flues, the unlined clay-tile chimneys in 1950s-1970s neighborhoods, and the freeze-thaw crown damage that accelerates at 5,430 feet. A technician who doesn’t understand these local conditions will sell you a cleaning you don’t need or miss a crown crack that’ll cost thousands in water damage by spring.
Our Fireplace Services in Boulder
Wood Burning Fireplace Service
Wood burning fireplace service in Boulder runs $220-$380 for a standard sweep and Level 2 inspection, or $1,800-$3,200 if we find spalling firebrick, deteriorated smoke chamber mortar, or a compromised flue liner that needs HeatShield resurfacing or full replacement. The thinner air at Boulder’s 5,430-foot elevation produces cooler, less complete combustion than at Denver’s 5,280 feet - more unburned hydrocarbons, faster Stage 2 and 3 creosote buildup. Annual cleaning is more urgent here than in lower-altitude Front Range cities with identical usage patterns.
We see original unlined or single-wythe clay-tile flues constantly in Table Mesa, Martin Acres, and Gunbarrel homes built 1955-1975. Many were never designed for the output of modern EPA-certified stoves or inserts. Our camera inspection shows you exactly what you’re venting into before we recommend any modification. Clause 1 of the Haven Standard - Have it in writing - means you get a written scope, written price, and written warranty before anyone lights a torch.
Gas Fireplace Service
Gas fireplace service in Boulder typically costs $180-$280 for a standard tune-up: burner cleaning, pilot and thermocouple testing, gas pressure verification, and venting inspection. In newer Boulder construction - particularly Gunbarrel and parts of North Boulder - we service direct-vent and B-vent units from major manufacturers. The same Chinook winds that damage masonry chimney caps can dislodge direct-vent termination hoods or crack their seals, creating CO risk that a standard appliance check won’t catch. We inspect the exterior termination as standard, not as an upsell.
Fireplace Insert Installation & Service
Fireplace insert installation in Boulder ranges $2,800-$5,500 depending on liner requirements, hearth modification, and whether your existing chimney needs a new stainless steel liner system or can accept a direct-connect kit. This is where the industry’s worst upselling happens: companies quoting full liner replacements on chimneys that only need a properly sized connector and a cap upgrade.
We drop the camera first. If your existing clay-tile liner is intact and properly sized for the insert’s BTU output, we’ll show you the footage and recommend the simpler, less expensive connection method. Our materials come through Haven’s buying network - DuraFlex for stainless liners, HeatShield for resurfacing - specifically to keep customer prices honest. The 365-Day Done Right Promise applies to every insert installation.
Damper Repair & Replacement
Damper repair in Boulder costs $180-$340 for a standard throat damper adjustment or replacement, or $650-$1,200 if you’re upgrading to a top-sealing damper that also functions as a chimney cap. On Boulder’s older homes - Mapleton Hill, Whittier, parts of University Hill - we find rusted cast-iron throat dampers frozen open or missing entirely, letting heated air escape and cold downdrafts enter. A top-sealing damper with a wind-directional cap solves both the energy loss and the Chinook backdraft problem in one installation. We stock Famco and Copperfield hardware for same-day repair when possible.
BeforeAfterTrusted Brands We Service in Boulder
We source materials through Haven’s buying network: DuraFlex stainless steel liners, HeatShield cerfractory resurfacing, Famco and Copperfield caps and dampers. For Boulder customers, this means replacement parts that don’t wait on freight from out of state. When a Chinook event tears a cap off a Martin Acres chimney or cracks a crown on Mapleton Hill, we can often source and install the correct component same-week rather than leaving you with a tarped flue through the next freeze-thaw cycle. Every part is documented in your photo record with manufacturer and model noted.
Common Fireplace Services Problems We See in Boulder Homes
- Chinook-induced backdraft mistaken for creosote blockage. On heavy Chinook days, the leeward pressure drop along the Flatirons forces smoke back down even clean, structurally sound chimneys. Homeowners call for emergency cleanings they’ve already paid for, when the real fix is a wind-directional cap upgrade. Our techs carry pressure meters and know how to read Boulder wind data to separate these conditions.
- Unlined mid-century clay-tile flues with appliances they were never designed for. In Table Mesa and Martin Acres, we regularly find original 1960s fireplaces now venting high-output inserts or stoves into single-wyhe clay tile with no stainless liner. The camera shows the gap between what the chimney was built for and what it’s handling now. Sometimes the fix is a liner. Sometimes it’s a smaller appliance. You see the footage before we recommend either.
- Freeze-thaw crown and flashing deterioration on rubble-stone chimneys. Mapleton Hill and Whittier homes with late-Victorian or Craftsman-era rubble-stone construction face dramatic thermal cycling. A Chinook day can swing temperatures 40°F in hours, opening hairline crown cracks into water pathways. Our Level 2 inspection catches these before water reaches the smoke chamber and requires rebuild-level repair.
- Missing or inadequate chimney caps after wind events. Boulder’s 100+ mph Chinook gusts destroy flat caps and standard weather caps that would survive normal Colorado conditions. We install wind-directional and pressure-differential caps rated for these specific loads, not the hardware-store grade that’ll be in your yard by November.

Call (970) 598-0453 to schedule.
A homeowner in the Table Mesa neighborhood called us after a 90 mph Chinook day backed smoke into their living room despite a recent cleaning. Our crew found original unlined clay-tile flue, spalling mortar in the firebox, and a missing chimney cap. We dropped a camera, showed the footage on screen, and installed a wind-directional cap alongside HeatShield resurfacing rather than selling a full liner they didn’t yet need. That’s the difference between a company that names what it found and one that sells what it hoped you’d buy.

FAQs - Fireplace Services in Boulder
It’s almost certainly a Chinook-driven pressure differential, not creosote. Boulder’s position at the mouth of the Flatirons corridor creates leeward downdrafts that can overcome normal chimney draw even in clean, structurally sound flues. Our techs carry pressure meters and cross-reference Boulder wind data to distinguish this from a blockage. The fix is usually a wind-directional cap upgrade, not another cleaning. Call (970) 598-0453 and we’ll diagnose it with the camera - estimates are free.
Yes. Thinner air means less oxygen per volume, cooler combustion temperatures, and more unburned hydrocarbons condensing in the flue as Stage 2 and 3 creosote. The physics is straightforward: a fire at 5,430 feet burns less completely than the same fire at 5,280 feet. Boulder homeowners with identical burning habits to Denver neighbors need more frequent cleaning, not less. We see the difference in our camera footage - thicker, harder creosote deposits at comparable usage hours. Call (970) 598-0453 to schedule and we’ll show you your flue condition on screen.
It shows the condition of every clay tile joint, any mortar loss between tiles, spalling or cracked tiles, creosote buildup by stage and location, and whether the flue is properly sized for whatever appliance is venting into it. On Table Mesa homes built 1960-1975, we typically find original construction with no stainless liner, sometimes with clay tiles shifted by decades of thermal cycling. The footage lets you watch as we find it, and your photo record documents it for insurance or future sale. Nothing is recommended without this evidence - Clause 4 of the Haven Standard requires it. Call (970) 598-0453 to book.
You don’t tell - we camera-inspect and tell you, with footage you can see. Mapleton Hill and Whittier rubble-stone chimneys from the 1880s-1920s were built for coal or small wood fires, not modern high-output inserts or stoves. The camera reveals whether the mortar between stones is intact, whether the flue gasses are channeling through unintended gaps, and whether the chimney has ever been lined. We will not clear a rubble-stone chimney for high-output use without documented evidence of liner integrity or proper sizing. The risk is real: unlined rubble stone can allow flue gasses to migrate into wall cavities. Call (970) 598-0453 for inspection and written assessment.
It can increase the urgency. Because Boulder County restricts wood burning to certified devices on action days, many residents burn infrequently but at high intensity when conditions allow - hotter, shorter fires that produce more thermal shock to aging fireboxes and can accelerate Stage 3 creosote formation. The “I only use it occasionally” homeowner sometimes has worse flue conditions than the daily user. Annual inspection is the baseline; if you’re burning on restricted days with an older appliance, we’d recommend checking mid-season. Call (970) 598-0453 and we’ll schedule around Boulder’s burn forecast.
