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

Why Alcott Chimney San Antonio Is Boerne’s Preferred Chimney Sweep Company
Boerne homeowners don’t want a stranger at the door. They want to know who’s coming, what they’ll see, and what it will cost before the work starts. That’s exactly how we’ve operated since 2002. Every Alcott technician is background-checked and identity-verified under what we call the Threshold Standard. Before the truck pulls into your driveway, you’ll get the technician’s name and photo so you know who to expect. They’ll show a photo ID badge at the door. No exceptions, ever.
Ruben Castellano leads our team, and he’s built Alcott around a simple rule: nothing gets recommended unless we can show you camera evidence. We don’t do mystery diagnoses. If we tell you a flue liner is cracked, you’ll see the image from our inspection camera. If we say the crown is spalling, we’ll point to the photo. Boerne homeowners tell us this is the difference between trusting a sweep and wondering if they’re being upsold. We also put a written price in your hand before any work begins, and every repair carries a written guarantee. If that repair fails within the coverage period, the second visit is free. That’s our 365-Day Done Right Promise.
Styles & brands we work with
Chimney Sweep Certified in Boerne
Chimney Sweep Certified work across Boerne means a full mechanical and manual cleaning of the firebox, smoke chamber, damper assembly, and flue liner, followed by a Level 1 visual inspection of all accessible areas. For most Boerne homes, this runs $189 – $289 for a single fireplace. On sprawling Hill Country properties with multiple masonry chimneys, we sweep and inspect each flue separately, and we’ll quote a flat per-flue price before we start so the total is never a surprise.
Soot and Creosote Removal on Hill Country Oak
Boerne sits in the heart of oak country. When you burn live oak or post oak that hasn’t been seasoned for at least 12 to 18 months, it smolders at low temperature and deposits a dense, tar-like creosote that brushes alone cannot remove. Our crews use rotary loops and HEPA-filtered vacuums to break down that glaze without sending dust through your house. If the buildup is advanced, we’ll tell you plainly and show you the camera feed.
Animal Nest Removal in Uncapped Flues
Older Boerne chimneys, especially the limestone ones along Main Street and in the downtown historic district, often lack proper caps. Ringtail cats and squirrels move in fast. We remove nests, sanitize the firebox, and can install a professional-grade cap from Olympia Chimney or Copperfield the same day. Every cap we install is sized to your flue and mortared or mechanically fastened, not just set in place.
Gas Fireplace Cleaning in Boerne
Gas Fireplace Cleaning in Boerne costs $149 – $189 for most direct-vent units and includes glass cleaning, log repositioning, burner inspection, and a check of the venting system for blockages or improper slope. Many newer Boerne subdivisions, including the stone-and-stucco builds along Esser Road and Champion Boulevard, have gas inserts that get ignored because homeowners assume they don’t need maintenance. They do. A dirty gas fireplace can vent carbon monoxide into the living room, and we check for that on every visit.
Glass, Burner, and Venting Checks
Gas inserts coat their interior glass with a white film that reduces heat output and looks bad. We remove the glass, clean it with a non-scratch cleaner, and inspect the gasket for deterioration before reinstalling. The burner gets checked for rust, uneven flames, and dirt at the ports. If the venting shows gaps or improper slope, we’ll photo-document it and give you a repair price in writing.
Moisture and Rain Cap Failures
Boerne thunderstorms in spring and summer can force water through a failed rain cap and into the gas valve assembly. We’ve replaced more rusted gas control modules on Hill Country homes than we can count. A visual check of the cap and seal is part of every gas fireplace cleaning, and we stock replacement caps locally so turnaround is quick.
Trusted Brands We Service in Boerne
We install and service professional trade materials, not box-store substitutes. That means DuraFlex liner systems for relining older masonry chimneys, HeatShield resurfacing for smoke chamber repair, and components from Olympia Chimney and Famco. If your Boerne home has a deteriorated clay flue or a gas insert venting into an unlined chimney, we’ll specify a DuraFlex or HeatShield repair and show you exactly why it’s the right fix. Because we stock these brands for Boerne jobs, most repairs are completed in a single visit.

AfterCommon Chimney Sweep Problems We See in Boerne Homes
- Ringtail cats and squirrels nesting in uncapped flues. The older limestone homes along Main Street and the historic district are especially vulnerable because many original chimneys were built without caps. We’ve pulled ringtail nests out of fireboxes that hadn’t been used in years.
- Third-degree creosote glaze from unseasoned oak. When a homeowner cuts a live oak off their Hill Country property and burns it the same season, the result is a dense, shiny creosote that standard brushes skip over. It can require rotary removal or chemical treatment to fully clear.
- Deteriorated flue liners in 1800s and early-1900s stone homes. Clay liners crack and spall over decades, and if you keep burning with a damaged liner, flue gases can leak into wall cavities. We use a Level 2 camera inspection to check what’s happening inside the flue before recommending any liner work.
- Water damage to crowns and flashing on custom masonry chimneys. Spring thunderstorms and summer heat in Boerne accelerate mortar deterioration. A cracked crown lets water run down the flue and into the smoke chamber, where it causes spalling. We check the crown, flashing, and cap on every sweep, not just the flue itself.

FAQs About Chimney Sweep in Boerne
Even if you only burn a fire on the three or four nights a year when Boerne gets a real freeze, you should still have an annual Level 1 inspection and sweep. Why? Because the infrequent, low-temperature fires common here produce slow creosote buildup that can go unnoticed for years, and uncapped chimneys attract animals even when the fireplace is never used. A single annual visit catches both problems early. Call (903) 515-5079 to schedule yours.
That shiny, tar-like material is third-degree creosote glaze, and in Boerne it usually comes from burning unseasoned oak off your own property. Live oak and post oak need 12 to 18 months of drying time before burning. When burned green or damp, they smolder and deposit dense glaze that a standard brush cannot remove. We use rotary tools and chemical treatments to get it out safely. If you’re seeing shiny buildup, schedule a sweep before your next fire.
Historic Boerne limestone chimneys require a Level 2 camera inspection before any mechanical sweeping, especially if the original clay flue liner is still present. The camera tells us whether the liner is cracked, spalled, or missing entirely. We also check the lime mortar in the firebox and smoke chamber, since modern portland cement repointing can damage original lime-based masonry. If repairs are needed, we’ll show you the camera images and give you a written price before anything is done.
Yes. We routinely sweep multi-flue homes across Boerne, including large custom estates off Ranger Creek Road and along Scenic Loop Road. A single visit covers all three fireplaces, and we price each flue separately so you see exactly what each one costs. On one recent estate off Ranger Creek Road, our crew swept three masonry chimneys with clay flue liners, applied a HeatShield resurfacing to a deteriorated smoke chamber, and converted a gas insert that had been venting into an unlined flue to a DuraFlex liner, then capped all three flues to stop the ringtail that had been nesting in the firebox. That’s a one-visit job for us.
A Level 2 inspection is a full camera scan of the entire flue interior, plus a check of the chimney crown, flashing, and accessible attic space. In Boerne, you need one after any animal intrusion, after a chimney fire, or before buying a home with an older chimney, especially in the historic district. It runs $249 – $349 and you receive a written report with photos. Every repair recommendation we make from that inspection comes with the images to back it up. Call (903) 515-5079 to book a Level 2 inspection.
