As an independent Gelco service provider, we’re not affiliated with or authorized by Gelco. We work on their products every season because San Antonio homes have a lot of them, and because their particular wear patterns are predictable once you’ve seen a few hundred. Danny Cortes and the crew at Kindling Chimney San Antonio have swept and inspected Gelco fireplaces across Alamo Heights, Terrell Hills, Stone Oak, and the older neighborhoods near the Pearl district. We know what to look for before the brush ever goes up the flue.

How Gelco Products Fail – and How We Fix Them

• Gelco prefabricated flue pipe (Gelco’s older double-wall air-cooled lines, common in homes built in the 1980s and 1990s across San Antonio’s north side). The inner liner on these units develops hairline cracks where the pipe sections meet, often visible only during a Level 2 camera inspection. What looks like routine soot buildup is sometimes fine creosote seeping into the air gap, which changes how the pipe cools. We camera-inspect before sweeping so you know whether you’re looking at a simple cleaning or a joint that needs attention. If it’s the latter, we show you the footage, sketch it out, and give a written price before touching anything.
• Creosote glazing on Gelco’s refractory panel lines (the Gelco “GB” and “GC” series fireboxes seen across San Antonio’s ranch-style homes). San Antonio’s burn season tends to be short and intense, and many families burn oak or mesquite that hasn’t fully seasoned. That creates a hard, shiny creosote layer that a standard flat-wire brush will skate right over. We use rotary loop systems and, where needed, chemical creosote treatment applied in stages. The goal is a clean, residue-free flue without damaging the refractory panels behind it.
• Damper plate warping on Gelco’s cast-iron throat dampers. This is one of the most common findings on older Gelco installations in San Antonio: the damper plate bows slightly from heat cycling, and it no longer seals fully. Owners notice a draft when the fireplace isn’t in use, or a faint smoke smell in summer. A sweep won’t fix this, but we’ll flag it honestly during the Level 1 and give you a repair number only if you want it. No pressure, no bundling.
• Flue cap and spark arrestor clogging on Gelco chimney terminations. The mesh on Gelco’s standard round terminations is fine enough to clog with creosote and the cottonwood fuzz that blows through San Antonio in spring. A clogged cap reduces draft and pushes smoke back into the room. We remove, clean, and re-seat the cap as part of the sweep, and we’ll tell you if the mesh has reached the point where replacement makes more sense than cleaning.
• Ash dump and cleanout door misalignment on Gelco masonry-adaptor models. Some Gelco installations in older San Antonio homes near the Pearl and Government Hill were retrofitted onto existing masonry chimneys. The cleanout door at the base of the chimney gets warped or mis-seated over time, and ash spills into the chase. We vacuum the entire chase cavity during a sweep, check the door seal, and show you a photo before we button it back up. It’s a small thing, but it’s the difference between a clean hearth and ash dust settling on your floors a week later.

Our Gelco Chimney Sweep Process

1. 1
   You call (361) 491-3153. A live person answers, takes your address and a few notes about your fireplace, and schedules a time that works. No voicemail trees, no callbacks hours later.
2. 2
   The crew arrives in uniform, wearing shoe covers before stepping inside. Drop cloths go down around the hearth and the path to the front door. Nothing gets moved without asking. Kids and pets stay safe because the work zone is contained and clearly marked.
3. 3
   We run a Level 1 inspection first. This is the part where we look at the firebox, damper, flue, and cap, and sketch what we see in a small notebook so you’re looking at the same picture we are. If we suspect a deeper problem, we recommend a Level 2 camera inspection before we sweep. You approve it, you see the footage, and you get the written price before we proceed.
4. 4
   The sweep itself is done with rotary tools suited to the flue type. For Gelco prefabricated systems, that means brush types and speeds calibrated to the pipe’s inner dimensions so we’re not scoring the liner. For masonry adaptations, we switch to the appropriate system. Pet-safe products are used where there’s a choice.
5. 5
   After the sweep, we clean the hearth, the interior of the fireplace, and the surrounding floor area, then photograph the cleanup. You see exactly what we saw before we leave. The photo is part of the Cedarwell Care Promise on every job.
6. 6
   We walk you through the findings and hand you the written report. Every job is backed by the 365-Day Done Right Promise: if it’s not right, we make it right.

What Gelco Chimney Sweep Costs in San Antonio

For a standard Gelco fireplace in San Antonio, expect a Level 1 inspection plus full sweep to run $189 to $289. That’s the honest range, and it’s the price you’ll see on the written quote before any work begins. If we recommend a Level 2 camera inspection because the flue hasn’t been looked at in years or there are signs of joint compromise, that adds $100 to $150. A creosote treatment for moderate glazing runs $80 to $120. A replacement Gelco flue cap, if yours is clogged beyond cleaning, typically lands between $65 and $140 depending on the cap size. The biggest price mover is always creosote stage and flue accessibility. If your fireplace has been used heavily without sweeping for three or more seasons, the labor side climbs. What doesn’t change is the no-pressure approach: the written price comes first, the work comes second, and nothing gets added at the doorstep. Call (361) 491-3153 for a free estimate. We’ll tell you what we think it needs, and we’ll tell you if it can wait.

Why San Antonio Homeowners Call Kindling Chimney San Antonio for Gelco Work

San Antonio has no shortage of companies with a brush and a truck. What brings families to us is the way the crew moves through the house. A background-checked, uniformed technician shows up on time, puts shoe covers on before stepping off the porch, and lays drop cloths before any equipment comes inside. The C.A.R.E. values get referenced by name and letter on the job: Cleanliness, Accountability, Respect, and Expertise. That means a photo of the cleanup before the crew leaves, a written price before any work starts, and a technician who can explain a Gelco flue joint issue in plain English instead of pushing a liner replacement you don’t need. And because there are times a Gelco fireplace needs more than a sweep, we also work with DuraFlex and HeatShield products, so the repair path is a real decision, not a default upsell. Danny Cortes has walked enough San Antonio homeowners through their flue sketches to know that honesty lands better than urgency.
