Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Cibolo
A standard chimney sweep in Cibolo runs $189 to $289 for a single flue with no repairs, and most jobs are finished in under two hours. That price includes a full cleaning of the firebox, damper, and smoke chamber, plus a written condition report with photos from our camera scan. If you live near Main Street, in Deer Creek, or out toward Wiederstein Road, call (903) 515-5079 and we’ll get you scheduled without a callback queue.
We have spent years working on Cibolo’s unusual mix of chimneys: brand-new prefabricated metal systems in recently built subdivisions, and older masonry fireplaces from the 1980s through the 2000s that were often constructed without modern flue liners. That matters because the right approach is not the same for both. A new prefab chimney needs a different inspection, different parts, and a different cleaning technique than a 1995 brick fireplace off Schaefer Road. Our Chimney Sweep team knows which is which before we even ring the doorbell.
Why Alcott Chimney San Antonio Is Cibolo’s Preferred Chimney Sweep Company
Ruben Castellano built Alcott Chimney San Antonio around a simple promise: you will know exactly who is coming to your door before they arrive. Every technician is background-checked and identity-verified under the Threshold Standard, and we send you their name and photo before the visit. When they arrive, they show a photo ID badge. No exceptions. For a homeowner in Cibolo who is often alone, has young kids, or just does not want to open the door to a stranger in a truck, that changes the whole experience.
We also answer the phone with a live person around the clock. If you smell smoke at 11 p.m. during a cold snap and you are not sure whether it is normal or dangerous, you get a real human. Not a voicemail. Not a “we’ll call you back within one business day.” That matters when the heat kicks on and the chimney starts doing something it should not.
Our local reputation in Cibolo has grown for one specific reason: we show our work. After every sweep, you get a camera inspection report with photos of the flue before and after. If we recommend a repair, you will see the problem in the photo. If nothing is wrong, you will see that too. That is how Ruben Castellano built Alcott since 2002, and it is the same standard the Chimney Sweep in Cibolo team holds to on every single job.

Gas Fireplace Cleaning in Cibolo
Gas Fireplace Cleaning in Cibolo is a service a surprising number of homeowners do not realize they need. Many of the newer homes in Cibolo, especially the ones built in the last ten years along the I-35 corridor and in the subdivisions behind the high school, came with factory-built gas fireplaces and vented gas logs. The seller, the builder, often the neighbors all said the same thing: “It’s gas. It does not need cleaning.” That is wrong. Gas fireplaces still accumulate soot on the glass, dust and pet hair on the burner, and debris inside the vent. More importantly, the gas log placement drifts over time. If the logs sit too close to the burner, they burn inefficiently and produce carbon monoxide. A gas fireplace cleaning in Cibolo runs $149 to $229 depending on whether we are servicing a direct vent, B-vent, or ventless unit and whether the glass needs deep cleaning.
What Our Gas Fireplace Service Includes
We pull the logs, vacuum the burner and valve area, clean the glass with ceramic-safe cleaner, inspect the venting, and test the ignition. If the thermocouple or thermopile is tired, we will tell you before it fails. Gas fireplace repair is one of our core services, and catching a failing thermopile in November is far cheaper than replacing the standing pilot in January.
When Cibolo Homeowners Should Book This
Book before the first cold snap. Cibolo gets maybe a dozen or two genuinely cold nights a year, and most families use their fireplaces for atmosphere more than heat. That intermittent use means sediment and soot build slowly over a season or two, and then one evening the burner starts clicking and will not light. If we service it before heating season, you avoid the scramble.
Chimney Maintenance in Cibolo
Chimney Maintenance in Cibolo is not just an annual sweep. It is a yearly check of every component between the firebox and the flue cap, and it is the single most effective way to avoid a four-figure repair bill later. In Cibolo, that means checking for rust on metal components caused by our high humidity, hard creosote that baked on during the off-season, and any masonry efflorescence on older brick chimneys. A maintenance visit, including a sweeping where needed, typically runs $189 to $289 for a single flue. Homes with older masonry or prefab systems that have never been inspected may need a Level 2 camera inspection, which we quote separately and always in writing before any work begins.
Seasonal Maintenance Before the Burning Season
In Cibolo, the burning season is short but intense. Families that have not used the fireplace since February fire it up again in late November, often ignoring a season or two of accumulated creosote. Hard creosote, the tar-like glaze that causes chimney fires, is far more common in humid climates because it absorbs moisture and hardens rather than flaking off. Our pre-season maintenance catches this before the first fire, not after the first scare.
What a Chimney Maintenance Visit Actually Covers
We sweep the flue, check the damper operation, inspect the chimney cap and spark arrestor, look for water intrusion at the crown, verify the firebox refractory panels are not cracked, and run a camera up the flue when the situation calls for it. If your chimney was built during Cibolo’s 1980s and 1990s growth years, we pay extra attention to the smoke chamber. That is the part of the chimney directly above the firebox, and in many Cibolo homes from that era, it was poorly designed. A defective smoke chamber is the leading cause of the smoke blowback we see in older neighborhoods along Main Street and around Cibolo Creek.
Trusted Brands We Service in Cibolo
We work with professional trade brands, not box-store substitutes. When a Cibolo home needs a new chimney cap, a replacement damper, or a full liner system, we use DuraFlex for stainless steel liners and Olympia Chimney for caps and chase covers. For factory-built prefab fireplaces in Cibolo’s newer homes, we carry and order manufacturer-specific parts rather than forcing a universal fit that will fail in two seasons. We stock common parts locally, which means most repairs on Cibolo prefab systems happen in one visit. If we need to special-order a manufacturer-specific component, we will tell you the exact timeline before you pay anything.

AfterCommon Chimney Sweep Problems We See in Cibolo Homes
- Missing or rusted chimney caps on prefab chases. Cibolo’s high humidity accelerates rust on metal chase tops and caps. Without a proper cap, rain gets into the flue, animals build nests, and the metal rusts faster. We regularly replace chase covers on homes that are less than ten years old.
- Third-degree creosote glaze on unlined masonry. Older homes near Main Street and along FM 78 often have fireplaces built without modern flue liners. Creosote bakes onto bare brick inside the flue, turns into a hard tar-like glaze, and requires specialized cleaning rather than a standard brush sweep.
- Smoke blowback from undersized smoke chambers. In Deer Creek and Buffalo Crossing, many original fireplaces from the 1980s and 1990s were built with smoke chambers that were too shallow or too narrow. Homeowners blame wet wood or wind, but the real culprit is the original design. We diagnose this with a Level 2 inspection.
- Neglected prefab systems in newer subdivisions. In Cibolo’s growing communities west of I-35, builders installed factory-built fireplaces, and homeowners assume a newer chimney needs no maintenance. The reality is that factory-built flue liners are thinner than masonry, and the cap and chase components are metal. In a humid climate, rust and hidden damage happen quickly. An inspection is cheap compared to a full prefab replacement.

FAQs About Chimney Sweep in Cibolo
Even a brand-new prefab chimney in Cibolo should be inspected at least every two years, and swept when the flue shows any creosote or debris accumulation. Prefab systems have thinner metal liners than masonry, and Cibolo’s humidity accelerates rust on the metal cap and chase. Newer does not mean maintenance-free.
In our experience, smoke blowback in Deer Creek and other 1980s – 1990s subdivisions is almost always a design flaw in the original smoke chamber or a missing damper. In one Deer Creek home, we found a firebox with no damper and an undersized smoke chamber. We corrected the chamber geometry and installed a proper damper, and after a Level 2 scan confirmed the flue liner was intact, the draft finally pulled cleanly. Call (903) 515-5079 if you are tired of smoke rolling back into the living room.
Yes. Cibolo’s high humidity absorbs into creosote deposits and hardens them into a glassy glaze that is far harder to remove than the flaky creosote common in drier climates. This is why we recommend annual sweeps even if you only burn a handful of fires each winter. The off-season is when the creosote hardens, not when it burns off.
Yes. Gas fireplace repair in Cibolo and cleaning is a standard part of our chimney sweep service. We clean the burner, logs, glass, and venting, and we test the ignition. Many newer homes in Cibolo have never had their gas fireplace serviced since the builder installed it. That leads to sooting, ignition failures, and occasionally carbon monoxide concerns that a simple cleaning fixes.
If your masonry chimney was built in the 1980s or 1990s without a liner, the answer is almost always yes. Bare brick flues allow creosote to soak into the masonry, and in Cibolo’s humid climate that creosote hardens into a glaze that cannot be brushed off. For homeowners needing Heatshield service in Cibolo, or a full reline, a DuraFlex stainless steel liner creates a smooth, insulated flue that holds up for decades. The only way to know for sure is with a camera inspection. Call (903) 515-5079 and we will show you the photos before recommending anything.
