Gelco Chimney Inspection in Austin: What to Know First
Gelco chimney inspection in Austin typically costs $189 – $349 for a Level 2 camera inspection, and we can usually get a technician to your home within 3 – 5 business days. As an independent Gelco service provider, we work on Gelco chimney caps, chase covers, and flue components daily across Austin, and we’ll give you a written price before any work begins. If you own a home with Gelco components and want to know exactly what’s happening inside that flue, call (361) 420-8585 for a straight answer and a free estimate.
This page is for Austin homeowners who have Gelco chimney caps, chase covers, or other Gelco components and need a real inspection, not a sales pitch. If you’re selling a home, buying one, or just haven’t looked at the flue in a few years, you’ll get the specifics below. Ruben Castellano and our crew inspect Gelco components the way we’d want them inspected on our own homes: with a camera, a written report, and no vague warnings.
How Gelco Products Fail, and How We Fix Them
- Gelco stainless steel chase covers develop pinhole rust at the corners. We see this on homes all over Austin, especially in Barton Hills and Tarrytown where tree canopy holds moisture against the chase. Gelco covers are solid products, but no stainless cover is immune to standing water at folded corners. The real cause is usually a slightly undersized cover or a chase top that doesn’t drain properly. We replace the cover with a properly measured Gelco or equivalent stainless unit and correct the drainage slope.
- Gelco multi-flue chimney caps trap debris at the flue tile junction. On Gelco caps with mesh screening, creosote and oak pollen from Austin’s live oaks collect where the cap meets the flue tile. That buildup restricts draft and can push carbon monoxide back into the house. During inspection, we remove the cap, clean the junction thoroughly, and check the mesh gauge, replacing it if the screening has begun to separate from the frame.
- Gelco single-flue caps with hinged lids seize after Austin’s freeze-thaw cycles. We get calls about this every spring. The hinge pin corrodes just enough to stick, and the lid won’t open when you light a fire. The fix is usually simple: we free the hinge, replace the pin with a stainless equivalent, and lubricate it with a high-temp graphite. But if the lid’s warped from being forced open, we recommend a new cap rather than patching it.
- Gelco damper assemblies can warp on homes where the fireplace gets overbuilt fires. People in areas like Mueller and Circle C love a big fire. Gelco dampers are cast well, but sustained high heat from oversized fires warps the frame and the damper won’t seat. We see this on maybe one in twelve Gelco inspections. If it’s minor, we address it; if it’s significant, we replace with a properly sized unit that handles the firebox volume correctly.
- Gelco top-mount dampers lose their seal when the silicone gasket dries out. Austin’s hot, dry summers cook the gasket material. After three or four seasons, it cracks and air leaks through the flue year-round. That’s a hidden energy cost and a draft problem. On inspection, we check the gasket by feel and with a smoke test, and we replace it with a high-temp silicone gasket rather than telling you to live with it.
Styles & brands we work with





Our Gelco Chimney Inspection Process
- 1
Call and talk to a person. You reach a live person any hour. We ask what you’re seeing: smoke backing up, a smell, a damper that sticks, or just time for a check. Ruben’s rule applies: “Tell me what you’re seeing, and I’ll tell you what it actually means.”
- 2
Technician arrives, announced by name and photo. Before we send anyone to your home in Austin, you’ll know their name and see their photo. They carry a photo ID badge and show it at the door. Every technician is background-checked and identity-verified under the Threshold Standard.
- 3
Full system walkthrough. We inspect the firebox, damper, flue, Gelco cap or chase components, and the exterior masonry. If you have a Gelco cap, we examine it specifically for the failure modes listed above. We use a camera system that records everything, so you see what we see.
- 4
Written findings and a written price. Before any repair, you get a written report with photos and a written price. No surprise charges at the end. If we see something that can safely wait, we tell you that plainly, and we show you the camera evidence.
- 5
Repair or component replacement. If work is needed on Gelco components, we use OEM Gelco parts when available and appropriate, and quality aftermarket equivalents when they perform as well or better for less money. We explain the difference before ordering anything.
- 6
Testing and the 365-Day Done Right Promise. After the work, we run a draft test and verify the system’s function. Every repair carries a written guarantee, and if it fails within the coverage period, the second visit is free.

AfterWhat Gelco Chimney Inspection Costs in Austin
A Level 1 visual inspection with a Gelco component check runs $149 – $199. A Level 2 camera inspection, which is what we recommend for most Austin homes with Gelco caps or dampers that haven’t been checked in three or more years, runs $189 – $349 depending on the flue configuration and access. If we find a failed Gelco component, replacement parts typically add $120 – $650 depending on whether it’s a gasket, a hinge assembly, a damper, or a full chase cover. You’ll see the exact number in writing before we touch anything. Call (361) 420-8585 for a free estimate on your specific setup.

FAQs
No. As an independent Gelco service provider, we inspect and service Gelco components without affecting your manufacturer’s warranty. We follow the manufacturer’s care and maintenance recommendations, and we document everything we do. If a warranty claim is ever needed, our written inspection report gives you the documentation the manufacturer usually requires.
Yes. We source Gelco components through professional supply channels and keep common items like damper gaskets, hinge pins, and cap hardware on the truck. When a full replacement component is needed, we order it and typically have it installed within one to two weeks. If lead time is longer, we’ll tell you before you commit to anything.
Most Austin homeowners get an inspection within 3 – 5 business days of calling. If you’re in a time-sensitive situation like a real estate closing, tell us when you call and we’ll work with your timeline as best we can. Call (361) 420-8585 and a live person will schedule you immediately.
It depends on what we find. A seized hinge or dried gasket is usually a simple repair that costs under $200. A rusted-out chase cover or a cap with separated mesh usually warrants replacement. During inspection, we’ll show you the camera evidence and give you the price for both options so you can decide with real information, not a guess.
You risk a chimney fire from creosote buildup, carbon monoxide from a blocked flue, or a Gelco component failing silently where you can’t see it. Gelco products are reliable, but they sit outside in Austin weather year-round, and no component lasts forever without inspection. A camera inspection catches issues before they become expensive or dangerous. Call (361) 420-8585 for a free estimate, and we’ll tell you honestly whether you actually need the work or not.
