We’re the only Boulder chimney sweep with a Class A contractor’s license, general liability insurance, and workers’ comp—so you’re covered if anything goes wrong. Our work comes with a 5-year warranty on repairs and a 1-year guarantee on waterproofing. No fly-by-night operators here; just a team that stands behind every brush stroke and mortar joint.
Industry standard is to nickel-and-dime homeowners with ‘extra’ charges for ladder fees, disposal, or ‘special’ brushes. We don’t. Our quotes include labor, equipment, disposal, and cleanup—period. If you see a lower price elsewhere, ask for the fine print. You’ll find most ‘budget’ sweeps tack on $50–$150 after the job starts.
Chimney fires, carbon monoxide alarms, or a sudden realization that it’s been two years since your last sweep? We reserve same-day slots for emergencies and fill them first. Call before 10 AM, and we’ll be at your Boulder home by 2 PM. No waiting weeks for a ‘next available’ slot—just fast, reliable service when your chimney can’t wait.
We’ve serviced chimneys from Mapleton Hill to Gunbarrel, and we know Boulder’s unique challenges: altitude, freeze-thaw cycles, and the local preference for hardwoods like oak and cherry. Our crews use techniques tailored to Front Range conditions, so your chimney performs as well in January as it does in July.
At David Anderson Chimney LLC, we’re the budget-wise choice for Boulder homeowners who refuse to overpay for chimney care. Unlike big-name crews that pad estimates with hidden fees, we strip away the fluff and give you a straight quote upfront—so you know exactly what you’re paying for before we even arrive. Our team specializes in spotting costly oversights in Boulder’s older homes, where decades of creosote buildup or cracked flues can turn a small repair into a $2,000 emergency. We don’t upsell; we educate, so you can decide what’s truly necessary for your chimney’s safety and longevity.
"Called on a Friday for a Sunday sweep—David’s team showed up on time, swept my entire flue, and even spotted a cracked liner I’d missed. Fixed price was $189, no add-ons. Highly recommend."
"After two other sweeps quoted $350 for the same work, David’s $220 price was a relief. The crew was thorough, cleaned up spotless, and even explained how to burn hotter with less creosote. Saved money and got better service."
"Had a chimney fire scare last winter. David’s Level 2 inspection found the cause—a blocked flue—and repaired it the same day. His warranty gave me peace of mind, and the $299 repair beat the $1,200 estimate from another company."
"My 1970s brick chimney was falling apart. David’s waterproofing job stopped the leaks in hours, and the 10-year warranty means I won’t have to worry about spalling for a decade. Local pros who actually care—rare these days."
"Scheduled a Saturday appointment, and David’s crew arrived early. They swept, inspected, and capped my chimney for $275—half what the big chains wanted. No upsells, no drama. Just good work at a fair price."
"Living just outside Boulder, I was skeptical about same-day service. David drove out, swept my chimney, and sent photos of the creosote levels. His $169 price beat the Lafayette sweeps who wanted $250. Local loyalty matters."

Proudly serving Boulder and these nearby communities.
In Boulder, a standard chimney sweep runs $120–$180 for a single flue, while Denver averages $150–$220 due to higher overhead. We keep costs lower by serving local clients directly—no franchise fees or middlemen. Ask for quotes from both and compare the line items; you’ll often find the ‘extra’ services in Denver quotes aren’t needed for Boulder homes.
Boulder’s altitude (5,430 ft) and frequent temperature swings accelerate creosote buildup faster than Fort Collins (5,003 ft). If you burn more than two cords of wood yearly, we recommend sweeping every 6–12 months. Lower-altitude homes can wait 1–2 years, but Boulder’s climate demands more frequent attention to prevent hazardous buildup.
No—Boulder’s 2018 building code requires a Level 2 inspection for any chimney serving a wood-burning appliance, regardless of age. Older homes may have hidden damage from past earthquakes or roof leaks, but even newer builds in Boulder’s Gunbarrel or Table Mesa neighborhoods need documentation for insurance or resale. It’s a one-time cost ($150–$250) that saves you from surprises later.
A standard sweep in Boulder takes 45–60 minutes, even during peak fire season. We schedule appointments back-to-back to minimize wait times, and our crews carry extra equipment to handle Boulder’s tight driveways and steep driveways in the Flatirons area. If you’re in a rush, ask about our early-morning slots—we’re often done before 9 AM.
The $99 sweep in Boulder is often a rushed, surface-level job that misses creosote in hard-to-reach areas or cracks in the flue. Our $149 includes a full inspection with a camera, a written report, and a creosote depth measurement—critical for Boulder homes with older masonry. You’re paying for precision, not just a quick brush-through.
Yes—most Boulder HOAs, like those in Wonderland Hills or Holiday, mandate annual chimney inspections for rental units to reduce fire risks. We provide the documentation HOAs need for compliance, and our reports include photos of any violations. Skip it, and you risk fines or insurance denials.
Signs your Boulder chimney needs a liner include smoke backing into the room, a strong campfire smell indoors, or visible cracks in the flue tiles. We inspect liners during every sweep and can install a stainless-steel liner in one day for $800–$1,500—far cheaper than repairing water damage from a failed liner later.
Gas fireplaces in Boulder often require a different brush size and extra venting checks, which adds 20–30 minutes to the job. We charge $150–$200 for gas sweeps because the work is more technical, but it’s still cheaper than the $300+ some Denver companies charge. Always confirm the scope of work upfront to avoid surprises.
