Gelco Chimney Inspection in San Antonio: What to Know First
We provide independent Gelco chimney inspection in San Antonio, typically completing a thorough Level 1 or Level 2 inspection within 60 to 90 minutes depending on the flue setup and the age of your Gelco liner or cap. Most standard inspections run between $189 and $289, and we hand you a written price before any work begins, so you’ll never get a surprise bill at the door. This page is for San Antonio homeowners who own a Gelco chimney product and want a straight answer about whether it’s still doing its job. If you’re ready to schedule, call us at (361) 491-3153 and we’ll find a time that works.

How Gelco Products Fail – and How We Fix Them
- Gelco stainless steel caps with screen mesh that clogs fast. San Antonio’s oak and pecan pollen clings to the fine mesh on Gelco’s standard caps, and once that mesh loads up, draft suffers and smoke starts pushing back into the living room. We see this most on homes in Alamo Heights and Terrell Hills where mature trees sit close to the roofline. The fix is straightforward: remove the cap, clean the mesh, and if the screen is deformed or rusting at the welds, we’ll quote a replacement cap before you pay a dime.
- Gelco chase covers with failed caulk beads and water intrusion. On prefab chimney chases, the factory caulk between the Gelco chase cover and the surrounding metal flashing dries out under San Antonio’s sun, then cracks during our hard freezes. Water creeps in, rusts the cover from underneath, and eventually drips onto the firebox. Danny Cortes will often sketch the corrosion pattern in his notebook so you can see exactly where the seal failed. We fix it by removing the old caulk, treating any surface rust, and resealing with a high-temperature silicone rated for exterior metal.
- Gelco multi-flue caps with misaligned mounting brackets. On homes with two flues, we regularly find Gelco multi-flue caps that were installed with brackets torqued unevenly, leaving one side lifted just enough to let rain blow in during a Texas thunderstorm. The symptom is usually a damp smell near the fireplace after heavy rain. We square the brackets, replace any stripped hardware, and verify the cap sits level on both flues before we climb down.
- Gelco liners in prefab fireplaces where the firebox has shifted. San Antonio’s clay soil expands and contracts with our wet-dry cycles, and some older additions see enough slab movement that the fireplace shifts a quarter inch or so. That’s enough to crack the refractory panels and pinch a Gelco liner where it passes through the smoke chamber. We spot this during a camera inspection, and we’ll tell you plainly if the liner can be reseated or if the fireplace needs more involved repair.
- Gelco dampers that seize from creosote and humidity. The combination of creosote buildup and San Antonio’s summer humidity turns a Gelco throat damper stiff, then seized. When the damper won’t fully open, smoke rolls into the room on startup. We clean the damper track, lubricate the pivot points with a dry graphite that won’t attract soot, and test the full open-close range before we call the job done.

Our Gelco Chimney Inspection Process
- 1
You call, a person answers. No voicemail trees. We talk through what you’re seeing, whether it’s a draft problem, a smell, or just a routine check, and we book a window that works around your family’s schedule.
- 2
The technician arrives and protects your home first. Shoe covers go on at the door, drop cloths go down around the hearth, and we ask before moving anything. Your floors, your furniture, your air. That’s the Cedarwell Care Promise, spelled out.
- 3
We inspect the firebox, damper, and flue by eye and then with a camera. On a Gelco setup, we’re looking specifically at the cap, the chase cover, the liner joints, and the damper operation. You get a photo report, not a verbal summary.
- 4
We show you what we found before any work is quoted. Danny keeps a notebook on every job and sketches the flue conditions so you can see the problem rather than take our word for it. If the liner has a pinhole, you’ll see it on the camera screen.
- 5
We decide together on the fix, using Gelco parts where they’re available or a quality aftermarket equivalent when the OEM part is backordered or discontinued. We never patch a part that should be replaced, and we never replace a part that’s holding up fine. The written price comes before any repair begins.
- 6
We test, clean up, and photograph the clean-up. The fireplace gets a functional test. The area around your hearth gets vacuumed and wiped down. You get a photo of the finished clean-up before we leave, and the work is backed by our 365-Day Done Right Promise.

AfterWhat Gelco Chimney Inspection Costs in San Antonio
Here’s the honest math, San Antonio. A Level 1 visual inspection of a Gelco cap, damper, and accessible flue runs $189 to $229, which covers most annual checkups. A Level 2 camera inspection, which we recommend when you’ve bought a home, had a chimney fire, or noticed a sudden draft change, runs $289 to $389 depending on the flue’s height and whether we need roof access on a two-story home. If the inspection turns up a clogged cap mesh, the cleaning is usually included in the inspection price. If it turns up a failed chase cover or damaged liner, we’ll hand you a written repair quote right then, and you decide what happens next with zero pressure. Call (361) 491-3153 for a free estimate on the inspection itself.

FAQs
Once a year, before burning season starts in late fall, is the right cadence for most San Antonio homes with a Gelco cap and liner. Our humid summers and occasional hard freezes stress metal components, and an annual inspection catches caulk failures and mesh clogs before they become water damage or smoke problems. Call (361) 491-3153 to book your annual check, and we’ll get you on the calendar before the first cold snap.
No, a professional chimney inspection does not void a Gelco warranty, provided the inspection itself doesn’t involve drilling or modification. We document everything with photos, and if we find a defect that might fall under a Gelco warranty claim, we’ll note it clearly so you can submit it to the manufacturer. As an independent Gelco service provider, we’re not the ones approving or denying that claim, but we’ll give you an honest assessment of whether the part failed from a defect or from age and weather. Call (361) 491-3153 and we’ll walk you through what we found.
We can source Gelco parts for most current products, and when an OEM part is backordered or discontinued, we’ll recommend a quality aftermarket equivalent from a brand like DuraFlex or HeatShield. The aftermarket parts we use are made to the same dimensional specs, and we’ll point out any material differences so you understand what you’re paying for. You’ll always get a written price for both options when both are available. Call (361) 491-3153 for a straight answer on availability for your specific Gelco part.
A Level 2 inspection includes a full camera scan of the flue interior, which lets us see pinhole leaks, cracked mortar joints, and hidden corrosion that a visual check from the firebox or roof simply can’t reach. For Gelco owners, we’re specifically checking the liner-to-damper connection and the cap-to-flue joint, two places where small failures turn into big repairs. We recommend a Level 2 when you’ve bought a home with an existing fireplace, after any chimney fire, or if your draft suddenly changed. Call (361) 491-3153 to schedule a camera inspection with a technician who knows Gelco products.
Most inspections are scheduled within a few days of your call, and the inspection itself takes 60 to 90 minutes. We’ll always tell you if the fireplace can be used safely that same evening or if we found something that should be addressed before you light the first fire. A clean flue is the quietest safety feature in your home. Call (361) 491-3153 and we’ll get you scheduled.
