Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterCreosote Removal in Austin, TX
Creosote removal in Austin typically costs between $250 and $600 for a standard single-flue chimney, depending on how heavy the buildup is and whether you have a wood-burning fireplace or a wood stove. Left alone, creosote is the tar-like residue that causes the vast majority of chimney fires. At Alcott Chimney Austin, we remove it thoroughly, show you what we found, and back the work with a written guarantee. If you’re seeing thick black flakes or a shiny, tarred surface inside your flue, call us at (361) 420-8585 and we’ll give you a straight answer about what it’ll take to clean it.
Our full-service Chimney Cleaning & Sweep in Austin work always includes a creosote assessment, but removal isn’t a generic sweep. When creosote hardens into what chimney professionals call Stage 2 or Stage 3 glaze, a standard brush won’t touch it. That’s where the job becomes specialized, and that’s where a lot of Austin homeowners get caught off guard by companies that quote a low sweep price and then walk away without actually removing the dangerous buildup.
When You Need Creosote Removal
Creosote builds up every time you burn wood, but some situations make it accumulate faster and become genuinely hazardous. Here’s what we tell Austin homeowners to watch for:
- You see black, flaky deposits falling into the firebox. That’s Stage 2 creosote shedding from the flue walls. It means the buildup is already thick enough to be a fire hazard.
- The inside of your flue looks shiny or glassy, not dusty. That’s Stage 3 glaze creosote, the most flammable form. It’s common in Austin homes where fireplaces get used in short, hot bursts during our brief cold snaps, then sit dormant and let the residue bake in place.
- Your fires burn well but you smell a strong, acrid odor when the fireplace isn’t in use. Creosote off-gasses as the chimney warms and cools, and that smell is stronger on humid Austin days, which we get plenty of.
- It’s been longer than a year since your last sweep. The National Fire Protection Association recommends an annual inspection and cleaning. In Central Texas, where fireplaces get sporadic use, homeowners often skip years, and creosote hardens in ways that make the eventual removal more involved.
- You bought the house and don’t know the chimney’s history. We see this a lot in older Austin neighborhoods like Hyde Park, Travis Heights, and Allandale, where fireplaces have decades of layers from previous owners. If you can’t confirm when it was last cleaned, assume it needs attention.
- Your wood stove pipe has visible tar streaks near the seams. This is creosote weeping, and it means the internal temperature of your flue has been cycling in exactly the range that produces heavy buildup.
If you’re checking off more than one of these, don’t wait. A chimney fire doesn’t give you a warning. It burns hot, it can crack the flue liner, and in the worst cases it spreads into the framing of the house. The cost of removal is a fraction of what a chimney fire costs to repair.
Our Creosote Removal Process
We don’t just scrape at your chimney and call it done. Here’s exactly how we work, step by step, so you know what you’re paying for:
- Visual inspection and creosote staging. Ruben Castellano founded this company in 2002 on the principle that a customer should never pay for work they don’t understand. We start by showing you the creosote stage, one through three, using a camera or a mirror and a bright light if the flue has hard angles. Stage 1 is light soot, Stage 2 is flaky tar, Stage 3 is the shiny glaze that needs chemical or mechanical treatment.
- Written price before any work starts. After we see the flue, you get a written quote. No verbal estimate that balloons later. The price covers the full removal, the creosote treatment if glaze is present, and a final sweep to clear the loosened material. You approve it before our tools come off the truck.
- Containment and protection. We seal the fireplace opening with an industrial-grade barrier and run a HEPA-filtered vacuum system, so the creosote dust we dislodge doesn’t end up on your mantel, your floors, or in the air your family breathes. This matters in Austin, where many homes have open floor plans and drywall that hangs onto soot smells for months.
- Mechanical removal with rotary tools. For Stage 1 and 2 creosote, we use professional chimney sweeping equipment, including rotating loops and chains that break the buildup off the flue walls. For Stage 3 glaze, we use chemical treatments from manufacturers like Gelco that soften the hardened tar, then follow with rotary cleaning. This is not the stuff you buy at a big-box hardware store. We use trade-grade materials specified by chimney professionals.
- Flue inspection and liner assessment. Once the creosote is gone, we inspect the exposed flue liner for cracks, gaps, or damage. Creosote hides liner problems, and a lot of Austin homeowners only learn their liner is compromised after a removal exposes it. If we find damage, we’ll show you photos and give you a separate written quote for repairs, with no pressure and no obligation.
- Cleanup and a written guarantee. We leave the firebox cleaner than we found it. Every creosote removal comes with a written guarantee. If the buildup returns abnormally fast or we missed something, the second visit is free during the coverage period. That guarantee is part of our 365-Day Done Right Promise. It’s included on every job, not an add-on.
From start to finish, a standard creosote removal takes about 90 minutes to two hours. If you have a heavy Stage 3 glaze situation, plan for a longer visit, because the chemical treatment needs time to work before the mechanical removal phase.
Creosote Removal Pricing in Austin
We give real numbers because you deserve a real answer. Here’s what creosote removal in the Austin market looks like based on the condition of your flue:
| Creosote Condition | Typical Price Range | What’s Involved |
|---|---|---|
| Stage 1 (light soot) | $250 – $350 | Standard sweep, brush removal, inspection |
| Stage 2 (flaky tar) | $350 – $500 | Rotary cleaning, extra vacuum containment, post-removal inspection |
| Stage 3 (glaze) | $500 – $700+ | Chemical treatment (Gelco), rotary removal, possible liner assessment |
| Wood stove pipe (single) | $200 – $400 | Pipe disassembly, creosote removal, reassembly, seal check |
What moves the price in Austin specifically? First, the age of the house. Homes built before the 1980s, especially in neighborhoods like Bouldin Creek, Rosedale, and Crestview, often have larger flues or older masonry that’s absorbed creosote deep into the brick. That takes longer to clean properly. Second, roof access. A steep pitch or a clay tile roof line can add time and risk. Third, whether you have a fireplace insert or a wood stove, which requires disassembly. Fourth, whether prior owners burned unseasoned wood. Austin’s humid climate means firewood stored outside without cover often carries high moisture content, and wet wood produces significantly more creosote per fire.

FAQs – Creosote Removal
How much does creosote removal cost in Austin?
Creosote removal in Austin costs $250 to $700 or more, depending on the creosote stage and the type of chimney you have. A standard single-flue fireplace with Stage 2 buildup runs $350 to $500, while Stage 3 glazed creosote typically requires chemical treatment and costs $500 to $700 plus any liner repair that’s uncovered. Call (361) 420-8585 for a written quote based on your actual flue condition. Estimates are free and we give you the number before any work begins.
Can you remove creosote the same day?
Yes, in most cases we can complete creosote removal the same day we arrive, and we offer 24/7 live-answer phone support for urgent situations. The exception is heavy Stage 3 glaze, which may require a two-visit process when the chemical treatment needs extended dwell time. When you call (361) 420-8585, you’ll talk to a live person who can tell you what your situation likely requires.
Is it cheaper to remove creosote or replace the flue liner?
Creosote removal is almost always cheaper, costing $250 to $700, while a new flue liner in Austin typically runs $2,500 to $6,000 depending on the liner material and chimney height. But the two aren’t substitutes. Removal addresses the flammable buildup. A liner replacement addresses structural damage. If your liner is cracked or rusted through, removal alone won’t fix the underlying safety issue. We’ll show you what the flue looks like after removal and give you an honest recommendation either way.
How often should I have creosote removed in Austin?
For wood-burning fireplaces in Austin, plan on a creosote inspection and cleaning every year, or after every cord of wood burned, whichever comes first. Our humid climate and sporadic burning patterns mean creosote can harden during long dormant stretches, which makes annual attention more important, not less. If you use your fireplace infrequently, you may get two seasons between removals, but the only way to know is an inspection. We’ll tell you if you can safely wait and we’ll put that in writing.
Who handles my creosote removal, and how do I know I can trust them?
You’ll know the technician’s name and see their photo before anyone shows up at your door. Every Alcott Chimney Austin technician is background-checked and identity-verified through the Threshold Standard, and they carry a photo ID badge that they’re required to show at the door, every time, no exceptions. This isn’t an optional upgrade. It’s how we’ve operated since 2002. Ruben Castellano built this company for homeowners who want certainty about who’s entering their home, and that standard applies to every visit, from a simple inspection to a full creosote removal.
