Fast, Reliable Chimney Cleaning & Sweep Across Boulder
Chimney cleaning and sweep in Boulder typically runs $180-$320 for a standard Level 1 cleaning with inspection, and most appointments are completed in a single visit. Our technicians are familiar with the specific challenges of Boulder’s aging housing stock and high-elevation burn conditions, from Mapleton Hill’s historic masonry chimneys to the terra-cotta flue liners common in Table Mesa ranch homes.
We’ve been driving to Boulder from our base for over 42 years. We know the difference between a chimney that needs a routine sweep and one that’s been stressed by Boulder’s Chinook winds or compromised by decades of freeze-thaw cycling at 5,430 feet. When you call (844) 803-1545, a live person answers, day or night. We’ll give you a real arrival window, not a four-hour guess. And we’ll show up when we say.
Why Hearthstone Chimney Co. Is Boulder’s Preferred Chimney Cleaning & Sweep Company
Boulder homeowners tend to stay put. They’ve owned their houses long enough to know which contractors return calls and which ones don’t. We’ve earned repeat business here through steady work, not flashy marketing. Our Chimney Cleaning & Sweep team documents every inspection with photos you can see and a plain-English verdict you can understand.
Our reviews from Boulder customers consistently mention the same things: the technician arrived on time, explained what was actually wrong, and left no mess behind. We don’t subcontract. Our background-checked, uniformed technicians complete most jobs in a single visit, with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Response time to Boulder is typically same-day or next-day for standard appointments, and we prioritize calls from the 80322, 80323, 80328, and 80329 ZIP codes. We understand Boulder’s air-quality wood-burning restrictions and schedule accordingly during burn season. When Stage 1 or Stage 2 no-burn days are called, a clean, draft-efficient chimney matters even more, because your legal burn window is already narrow.
Local knowledge makes a difference here. We know that a chimney cap blown off in a 100-mph downslope wind event needs more than a replacement; it needs proper securing for Boulder’s specific conditions. We’ve replaced enough caps on Baseline Road homes to know which mounting methods hold.
Our Chimney Cleaning & Sweep Services in Boulder
Level 1 Inspection
A Level 1 inspection is the standard annual check for chimneys with no known changes or problems. In Boulder, we perform these most often for homeowners in south and east Boulder neighborhoods like Table Mesa, where 1960s-70s ranch homes with original terra-cotta flue liners need regular monitoring for cracking. We examine the readily accessible portions of the chimney structure, flue, and connections, and we document our findings with photos. A Level 1 inspection paired with a sweep in Boulder runs $180-$240.
Level 2 Inspection
Level 2 inspections are required when a property changes hands, after a chimney fire or weather event, or before installing a new appliance. This is where our camera inspection becomes essential. We run a high-resolution camera through the full flue length, and the footage goes straight to you with a plain-English verdict. In Mapleton Hill and other historic districts, we frequently find that a modern insert was dropped into an original 1910s-1920s flue with no relining, creating a dangerous diameter mismatch that pools condensate and creosote. Our Level 2 inspection in Boulder is $280-$380, and it includes the full video documentation.
Creosote Removal
Boulder’s elevation produces slightly lower combustion efficiency in wood-burning appliances, which increases unburned particulate and accelerates creosote buildup, especially in older, oversized masonry chimneys that were never relined. Stage 1 creosote (sooty, brushable) and Stage 2 creosote (shiny, hardened flakes) are what we remove in routine sweeps. Stage 3 creosote, the tar-like glaze that requires chemical treatment or rotary removal, is more common in chimneys that haven’t been serviced in multiple seasons. Creosote removal in Boulder ranges from $180-$320 for routine buildup, and $380-$520 for heavy Stage 3 glazing requiring specialized treatment.
Soot Removal and Fireplace Cleaning
Soot accumulation isn’t just a fire hazard; it restricts draft and reduces the efficiency of your entire system. In Boulder, where temperature inversions already limit your burn days, you can’t afford a chimney that’s drawing poorly. We remove soot from fireboxes, smoke chambers, and flues, and we clean the fireplace surround without damaging original tile or brickwork, which matters in historic homes. Fireplace cleaning and soot removal in Boulder typically runs $160-$260. We also handle Fireplace Services in Boulder for more extensive restoration needs.

Trusted Brands We Service in Boulder
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, and Copperfield, so most repairs that surface during a cleaning can be completed on the spot without a return visit. For Boulder homeowners, that means faster turnaround and no waiting on parts shipments from out of state. When we find a cracked flue liner in a Baseline Road ranch home or a deteriorated crown in Mapleton Hill, we have the right materials to fix it correctly the first time. Done right, and we stand behind it.
Common Chimney Cleaning & Sweep Problems We See in Boulder Homes
- Chimney caps blown off by Chinook winds. Boulder’s documented 100-mph downslope gusts rip off poorly secured caps and damage mesh screens. We find this most often after wind events in homes near the mouth of Boulder Canyon, and we reinstall with proper mounting for local conditions.
- Freeze-thaw mortar damage on historic chimneys. Mapleton Hill’s 1880s-1920s masonry chimneys suffer accelerated mortar joint failure from Boulder’s rapid temperature swings. We spot this early during camera inspections before water intrusion requires a full rebuild.
- Oversized flues with modern inserts. A common scenario in Boulder’s protected historic districts: the homeowner upgraded to an efficient insert but left the original 12×12 flue unlined. The resulting draft mismatch pools condensate and creosote in dangerous quantities. Our Level 2 inspection catches this before it becomes a hazard.
- Cracked terra-cotta flue liners in 1960s-70s ranch homes. Table Mesa and similar neighborhoods are dense with these now 50-60-year-old liners. The clay becomes brittle from decades of thermal cycling at elevation, and cracks allow flue gases into wall cavities.
