How Gelco Products Fail – and How We Fix Them

Gelco makes solid chimney components, but every brand has patterns. Here’s what we actually see on Gelco jobs in San Antonio homes, and what we do about it.

• Gelco stainless steel liners and creosote adhesion. On Gelco rigid and flexible liner systems, the corrugated interior wall of flexible sections tends to hold creosote (the flammable tar buildup that makes chimneys a fire risk) tighter than smooth-wall alternatives. San Antonio’s winter burn cycles, short hot fires overnight followed by cool-downs, produce a sticky, glaze-prone creosote that clings to those ridges. We sweep with a poly brush sized to the liner, not a steel brush, because steel can scar the liner interior and give creosote more places to grab next season.
• Gelco caps and San Antonio’s rain-and-pollen combo. Gelco multi-flue caps and standard single-flue caps do their job, but the spring oak pollen in neighborhoods like Alamo Heights and Terrell Hills can pack the mesh screening within weeks. We see airflow restrictions that make fireplaces smoke back into the living room, not because the cap is defective, but because the mesh is doing exactly what it should and needs to be cleaned. Our sweep includes removing and clearing the cap mesh, a step a lot of companies skip.
• Gelco chase covers and rust-through at the corners. We work on plenty of Gelco prefabricated fireplace systems in San Antonio, and the chase cover (the metal lid at the top of your chimney chase) is the most common rust point we find. South Texas humidity, combined with the heat cycling of the flue, leads to corrosion at the bent corners and screw penetrations. If your Gelco chase cover is rusted through, water gets into the firebox. Our sweep includes checking the chase cover and reporting its condition with photos, so you’re not surprised later.
• Gelco damper plates and soot accumulation on the frame. Gelco top-sealing dampers are good units, but soot and fine ash build up on the damper frame over time, preventing a full seal even when the damper is closed. That means conditioned air from your San Antonio home leaks up the flue in summer, and in winter, you get a faint smoky smell in the house. Sweeping includes cleaning the damper frame and testing the seal, not just brushing the flue.
• Gelco firebrick and mortar joint erosion. On Gelco masonry-style zero-clearance fireplaces, the interior firebrick panels and mortar joints take a beating from years of heating and cooling. Spalling brick (when the surface starts to flake off in small pieces) is common on units that have seen ten or more seasons of regular use. We don’t just sweep around damaged brick; we document it with photos, explain whether it’s a structural issue or wear-and-tear, and give you the repair scope before any work happens.

Our Gelco Chimney Sweep Process

Here’s what happens when you book a Gelco chimney sweep with Hadley Chimney San Antonio, from the phone call to the final photo.

1. 1
   You call (254) 276-4116 and get a live person. They’ll ask about your Gelco unit, when it was last swept, and any issues you’ve noticed, smoke back in the house, a smell, visible soot. We book a tracked arrival window and you get a text with your technician’s name and a live arrival time.
2. 2
   We show up, drop cloths, and lay eyes on the firebox first. Our techs check the damper, firebrick, and flue opening before going to the roof, so we have a complete picture before anything is disturbed.
3. 3
   Full system photo documentation. Before we touch a brush, we photograph the interior of the flue and the firebox. You’ll see exactly what Cory Mitchell’s team sees, creosote levels, cracks, water stains, damper condition, before we quote anything beyond the sweep.
4. 4
   The sweep and component cleaning. We use poly brushes sized to Gelco liners, HEPA-filtered vacuums to control dust, and hand cleaning of the damper, smoke shelf, and cap mesh. Every accessible component gets worked, not just the flue walls.
5. 5
   Post-sweep camera inspection if needed. If creosote was heavy or we suspect liner damage, we run a Level 2 camera inspection. You get the video or stills sent to your phone. We don’t ask you to take our word on liner condition, we show it to you.
6. 6
   Written report, photos, and exact price. You get a written report with before-and-after photos, our findings, and any recommended repairs with a written price. Nothing is done beyond the sweep without your okay. Every repair we recommend is covered by our 365-Day Done Right Promise with a free second visit if it fails.
