Boulder homeowners trust Daniel Thompson Chimney because we’re the only licensed chimney sweep in the area with CSIA-certified crews, transparent pricing, and a focus on first-time homeowner safety. Unlike unlicensed crews, we inspect for hidden risks like creosote buildup or cracked flues, common in Boulder’s older homes, before cleaning. Our free estimates and 100% satisfaction guarantee remove the guesswork, so you can book with confidence.
1. A licensed chimney sweep in Boulder means safety, especially for older homes
Hiring a certified chimney technician in Boulder is much more than just checking a box. The city’s mix of historic homes (like those in Pearl Street or the Flatirons area) and newer builds with wood stoves creates unique risks. Creosote buildup, a flammable tar from wood smoke, is far more dangerous in Boulder’s dry, windy climate, where embers can ignite faster. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that 9 out of 10 chimney fires start from creosote. Our crew carries CSIA certification, insurance, and a Colorado state license, so you’re protected if something goes wrong. Unlike unlicensed crews, we also check for cracked flues (common in Boulder’s older masonry chimneys) and blocked caps, both fire hazards. Ask us how we inspect for these risks before cleaning.
2. They answer ‘Why does my chimney smell after sweeping?’ with a clear explanation (not just ‘it’s fine’)
Here’s a red flag: A chimney sweep who tells you a lingering smell after cleaning is ‘normal’ is lying. In Boulder, where homes often have older, unlined chimneys, leftover odors usually mean residue wasn’t fully removed or moisture is trapped in the flue. Our process includes brushing all three creosote stages (from dry powder to hard glaze) and using high-efficiency vacuums to capture every particle. We also check for water damage, a Boulder-specific issue, thanks to our sudden rain-snow cycles, which can leave a musty smell. If your chimney still smells after sweeping, it’s a sign the crew didn’t do a thorough job. We’ll show you exactly what we found during your inspection.
3. They explain chimney inspections in plain terms, no jargon, no upselling
A chimney inspection is a visual and instrumental check of your chimney’s structure, connections, and flue to spot hidden damage. In Boulder, where masonry chimneys (common in older homes) and modern stainless-steel liners (in newer builds) behave differently, this step is critical. Our Level 2 inspections (the most thorough) include: - Checking for cracks or spalling (where bricks chip away, common in Boulder’s freeze-thaw cycles). - Testing draft flow (to ensure smoke exits properly, not into your home). - Inspecting the smoke chamber (where fires start; often overlooked by cheaper crews). We’ll never recommend repairs you don’t need, but we’ll always explain what we find, like why your Boulder-built brick chimney might need repointing after 20 years. See our inspection process step-by-step.
4. They charge by the job, not the hour, with no surprise fees for Boulder’s tricky chimneys
Pricing transparency is a dealbreaker for Boulder homeowners. Some crews quote $120–$250 for a sweep but hit you with $50–$100 “travel fees” for steep driveways (like those near Chautauqua Park) or $30–$50 “extra charges” for stubborn creosote. We price by chimney type and condition, not time. Here’s what you’ll pay in Boulder: | Chimney Type | Typical Cost Range | What’s Included | |------------------------|-----------------------|---------------------------------------------| | Wood stove (small) | $120–$180 | Full sweep, inspection, debris removal | | Masonry chimney (avg.) | $180–$300 | Brushing all creosote stages, cap check | | Stainless-steel liner | $150–$250 | Specialized tools, no damage to liner | | Inspection only | $80–$120 | Level 1 or 2, no cleaning | Get a free, no-obligation quote for your Boulder home, we’ll even factor in your chimney’s age and local conditions.
5. They’ll tell you if your Boulder home’s chimney needs repairs, without pressuring you
A trusted chimney sweep doesn’t just clean; they spot problems early before they become costly. In Boulder, cracked crowns (the top of your chimney) and deteriorating mortar joints are common after winter storms. We’ll explain: - Minor issues (like a loose cap) can often be fixed for $50–$150. - Major repairs (like relining a chimney) might cost $1,500–$4,000, but we’ll refer you to a licensed mason we trust, never upsell you ourselves. For example, if your 1920s home on Pearl Street has a brick chimney with spalling, we’ll show you photos and options. We partner with local masons for honest referrals, no hidden commissions.
6. They arrive on time, clean up thoroughly, and leave your home (and chimney) better than they found it
Boulder homeowners hate wasted time. We schedule appointments in 1–2 hour slots (not all day) and arrive within 15 minutes of your start time. Our crew: - Covers floors with drop cloths (no soot on your hardwood or carpet). - Vacuums debris from your fireplace, hearth, and even the roof area. - Washes tools on-site to avoid tracking dirt into your home. After we leave, your chimney should look cleaner than before, no lingering dust or missed spots. See our before-and-after photos from local Boulder homes.
7. They’re local, licensed, and backed by Boulder’s homeowners (not just reviews)
We’ve served Boulder since 2001, and our crew lives in the area, so we know the quirks of your home. For example: - Flatirons homes often have tall, narrow chimneys that require special tools. - North Boulder neighborhoods (like Gunbarrel) see more condensation issues from newer builds. - Historic homes downtown need gentler cleaning to preserve original masonry. We’re also insured and bonded, so if an accident happens (like a tool slipping on your roof), you’re covered. Meet our team and see our certifications, no generic stock photos.

Frequently Asked Questions
Is it too late to book a fall appointment for the fireplace in my new Boulder house?
No, it’s never too late, but the sooner you book, the safer your home will be. Boulder’s fall weather brings cooler nights and wind, which can push smoke back into your home if your chimney has creosote buildup. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends sweeping at least once a year, but if you’ve never had it done, we’ll do a full inspection first to check for hidden damage. Fall is our busiest season, so schedule now to avoid delays.
Why does my fireplace smoke more after a chimney sweep in Boulder? Is the sweep to blame?
Smoke after sweeping usually means one of three things: 1) Your damper isn’t fully open (common in older Boulder homes with manual dampers), 2) Creosote was pushed deeper into the flue (our crew uses rotating brushes to prevent this), or 3) Your chimney needs a liner (if it’s older than 30 years, like many in Boulder). We’ll test the draft and show you how to adjust the damper. If the issue persists, it might be time for a chimney relining, we’ll explain your options. Smoke issues often fix with a quick adjustment, we’ll walk you through it.
I found black soot on my fireplace glass after burning wood in my Boulder home. Is this normal, or did the sweep miss something?
Black soot on glass is normal if you’re burning unseasoned or resinous wood (like pine, which is common in Colorado). However, thick, tarry buildup on the glass, and inside the chimney, means creosote wasn’t fully removed. Our crew uses high-velocity vacuums to capture fine particles, but if you’re still seeing soot, it could mean: - Your fire isn’t hot enough (Boulder’s dry air helps fires burn cleaner, aim for 300°F+). - Your wood isn’t dry enough (store it under cover, not in your garage). We’ll check your chimney’s efficiency during your next sweep. Learn how to burn wood safely in Boulder’s climate.
Should I rebuild the chimney on my historic Boulder home or just stick to regular cleanings?
Older chimneys can be saved with proper maintenance, but masonry chimneys over 50 years old often need repointing, tuckpointing, or even a full rebuild. Signs it’s time to upgrade: - Cracks wider than 3/8 inch (common in Boulder’s freeze-thaw cycles). - Brick spalling (flaking bricks). - Water stains inside your home near the chimney. We’ll inspect your chimney’s structure and give you cost estimates for repairs vs. replacement. Older Boulder homes often need chimney upgrades, we’ll help you decide.
