Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cleaning in Austin, CA | Alcott Chimney Sweep
We provide independent Gelco chimney cleaning, inspection, and repair across Austin, and the one thing that makes our Gelco work different here is the calendar. Because federally protected Chimney Swifts nest in Austin flues from roughly April through October, the legal window for cap work, damper replacement, and thorough cleaning compresses into November through early March. Alcott Chimney Sweep has offered our Chimney Sweep in Austin for Gelco factory-built and masonry systems since 2002, and we schedule around that reality, not against it. Call (336) 863-3889 to book your sweep or get a written estimate.
Why Austin Residents Choose Us for Gelco Service
Our sweep crews have serviced Gelco masonry and factory-built fireplace systems across Central Austin for years, accumulating hands-on familiarity with the brand’s damper, firebox, and cap assemblies that no manufacturer training pipeline provides. We’re independent specialists – not authorized, sponsored, or warranty-endorsed by Gelco – so our only incentive is diagnosing your actual chimney correctly. That independence matters in Austin, where a Gelco unit in a Hyde Park bungalow from 1940 behaves differently than the same model in a Northwest Hills ranch built in 1982. Ruben Castellano, our owner, learned heating and ventilation fundamentals through the HVAC and building trades program at East Los Angeles College before apprenticing under a veteran sweep, and he’s spent the better part of two decades working chimneys across climates like this one. We send every technician to you by name and photo before arrival, and every job comes with a written price before work begins. That’s how we’ve operated since 2002.
Common Gelco Chimney Cleaning Problems We Solve in Austin
- Cracked refractory panels in Gelco factory-built fireboxes. Austin’s 100°F+ summer heat cycles hit a unit that hasn’t been fired in months, and hairline cracks become full-depth gaps by the first blue norther. We inspect every panel before sweeping, because a cracked panel behind a clean-looking flue is still a fire risk.
- Top-sealing damper gaskets that dry out and fail. That long dormant warm season bakes the gasket until it loses its seal. Rain gets in, debris accumulates, and the open flue becomes an invitation for chimney swifts and squirrels. We replace Gelco-compatible gaskets regularly in Travis Heights and Bouldin Creek.
- Gelco multi-flue stainless caps corroding at welded seams. Austin’s expansive clay soil shifts chimney footings, which stresses the cap connections along the crown. A cap that looks fine from the ground can be rusted through at the weld points. We check these closely during every Austin sweep.
- Seized cast-iron dampers on Gelco masonry fireboxes. Austin’s humid spring rusts the damper in the open position, leaving the flue permanently exposed. In older homes across Clarksville and Hyde Park, this is one of the most common issues we find, and it’s fixable with a Gelco-compatible replacement.
- Nesting material from protected birds and other animals. A Gelco flue sitting dormant from March through October collects nesting debris. We remove it once the birds have fledged, and we can cap the chimney with a stainless Gelco-compatible multi-flue cap so it doesn’t happen again next year.
Gelco Service in Austin: What Local Conditions Mean for Your Equipment
Because Chimney Swifts occupy Austin flues from roughly April through October (longer than in cooler Texas cities on the birds’ central flyway), any Gelco cap or top-sealing damper work an Austin homeowner wants must be scheduled into the narrow November-to-early-March window, or it risks a federal Migratory Bird Treaty Act violation rather than a simple callback. A homeowner in Allandale called us in late July after hearing chattering from a Gelco factory-built fireplace whose top-sealing damper gasket had dry-rotted open, letting swifts into the flue. We confirmed an active nest, documented it, and rescheduled the Gelco multi-flue cap and damper replacement for November after the birds fledged. When we returned, our tech replaced the seized Gelco damper, installed a stainless multi-flue cap over the chase, and swept out the accumulated nesting material and light creosote. The family had a sealed, code-compliant flue before the first blue norther. That’s the Austin calendar in practice, and it’s why we run swift-inspection calls before booking any capping job from spring through fall.
Gelco Models & Products We Service in Austin
We work on Gelco Heatilator-style factory-built wood fireplace systems with knock-out panels and refractory-lined fireboxes, Gelco glass-door enclosures and bi-fold screen assemblies for masonry fireboxes, Gelco stainless multi-flue caps and top-sealing damper kits, and Gelco masonry firebox inserts with cast-iron grate and hearth accessories. We stock quality aftermarket Gelco-compatible dampers, gaskets, refractory panels, and multi-flue caps that meet or exceed OEM specs at a fraction of dealer markup, because original Gelco parts channels for older factory-built units are largely discontinued. That keeps Austin turnaround fast, and it means we’re not going to tell you to rebuild a sound firebox just because a dealer part isn’t available anymore. We also carry and install DuraFlex liner systems, HeatShield resurfacing, Olympia Chimney, Famco, and Copperfield – professional trade materials, not box-store substitutes. For a broader look at what we offer, see our Gelco sales & service page.
Gelco Service Pricing in Austin
A standard Gelco chimney sweep in Austin typically runs $189 to $289 before any repairs, depending on the system, the amount of creosote and nesting debris present, and how long it’s been since the last cleaning.

FAQs – Gelco Chimney Cleaning in Austin
No, not legally, if Chimney Swifts are nesting in the flue. The Migratory Bird Treaty Act protects swifts from April through October in Austin, and disturbing an active nest during that window is a federal violation. We run our Chimney Inspection in Austin first to confirm whether birds are present, and if they are, we schedule the capping work for November through early March. If the flue is clear, a cap can go in anytime. The safest first step is to call (336) 863-3889 and have us check before you cap.
If the firebox shell is still sound and the crack is limited to one or two refractory panels, replacing the panels is the right call, typically $350 to $800 with parts and labor. If the shell itself is heat-fatigued or the chimney chase is shifting with Austin’s clay soil movement, we’ll tell you rebuilding beats throwing parts at it. We’ll show you the cracked panel on camera before recommending anything, so you’re not taking a stranger’s word on a repair you can’t see. Call (336) 863-3889 if you want a straight answer on your specific unit.
In Austin, the most common cause is a gasket that dried out and lost its seal during the long dormant warm season, combined with rust or debris catching the plate in the open position. Spring humidity accelerates the rust, and before you know it, the damper won’t seat. We replace the gasket and clean the mechanism with Gelco-compatible parts, and in most cases the damper works like new. If it keeps failing after a replacement, the issue is usually the lever assembly, which we can address the same visit. Call (336) 863-3889 and tell me what you’re seeing and someone will tell you what it actually means.
Yes, it is common in Hyde Park, Travis Heights, and other Central Austin neighborhoods with 1920s-1950s bungalows, and the culprit is usually rust from Austin’s humid spring. Cast-iron dampers seize in the open position, leaving the flue exposed to nesting birds, rainwater, and downdrafts for months at a time. We replace the damper with a Gelco-compatible unit and verify the whole assembly operates before we leave, and we can cap the flue in the November-to-March window to keep swifts out next season. Call (336) 863-3889 for a written quote on the damper and cap together.
Yes, especially in Northwest Hills and along the South Lamar corridor, where ranch-style chimneys with multiple flues sit exposed to the full force of Austin’s sun, heat, and clay-soil footing movement. A Gelco-compatible stainless multi-flue cap keeps rain, debris, swifts, and squirrels out of every flue and resists the seam corrosion that plain-galvanized caps don’t. You’ll get a written price before we install anything, and the cap carries the same written guarantee as every repair we do. Call (336) 863-3889 if you want us to take a look at your cap and crown.
