Gelco Chimney Cleaning in Plano, TX | Ashby Chimney Dallas
We clean, inspect, and repair Gelco chimney systems across Plano, and we do it as an independent service provider, not a manufacturer shop. Most Gelco chimneys in Plano never burn a single log. They sit on gas fireplaces inside brick veneer homes, quietly rusting at the chase cover until the first big storm or humid stretch pushes water into the ceiling. Call (361) 314-3193 and we’ll tell you the price before we touch anything.
Why Plano Residents Choose Us for Gelco Service
Nathan Corliss, our owner, has been running chimney crews in the Dallas area for well over a decade. He learned the trade at Los Angeles Trade-Technical College and has worked on everything from old masonry fireboxes to prefab inserts. That matters when you own a Gelco system, because Gelco chimneys are factory-built, precision-fit products. They’re not forgiving when someone guesses.
We know the Gelco product lines: Thermo-Safe, SS II, and Ventinox. We know how their twist-lock joints behave after a few North Texas freeze-thaw cycles. We know what the factory chase covers look like after eight summers of Plano humidity. And we carry or can quickly source OEM-compatible parts so you’re not waiting weeks. See our full Gelco sales & service background for more on how we work with the brand.

Common Gelco Chimney Cleaning Problems We Solve in Plano
Here’s what we actually find on Gelco chimneys in Plano, in order of how often we see it:
- Rusted factory chase covers. Gelco’s original chase covers are thin metal, and Plano’s hot, humid summers are brutal on them. Water seeps through pinholes, runs down the chimney pipe, and shows up as a brown stain on the ceiling below. We replace the cover with a heavier-gauge stainless fabrication and seal the penetration properly.
- Separated twist-lock joints. The Thermo-Safe sections lock together with a twist, but repeated freeze-thaw cycles in Plano winters can work them loose. Once a joint separates, birds and squirrels find their way inside. We realign and re-seat the sections, then cap the flue to keep animals out.
- Corroded galvanized pipe at the roof flashing. Plano homes with south-facing roof slopes bake in the sun all afternoon. Gelco’s galvanized exterior pipe can corrode exactly where it meets the flashing, and that’s a leak waiting to happen. We inspect that transition point on every roof we walk.
- Warped inner stainless liner on direct-vent gas systems. Gas fireplaces cycle heat through the inner liner repeatedly. Over years, that liner can warp or crack. You’ll notice it as a gas smell in the room or a fireplace that won’t draft right. We use a camera to confirm before recommending any repair.
- Animal nests inside unused flues. In Plano, most Gelco flues never see a fire. Squirrels and birds don’t care. They build nests, and those nests block airflow and hold moisture against the metal. We remove the nest, inspect for damage, and fit a proper chimney cap.
Gelco Service in Plano: What Local Conditions Mean for Your Equipment
Plano’s master-planned communities like Legacy and Willow Bend are full of Gelco chimneys that have decorative brick facades but flues that have never burned a single log. Those chimneys are architectural, not functional, and homeowners rarely think about them until water stains appear on a ceiling. The failure that gets us called out most often is a rusted chase cover discovered after the first big spring storm. The cover rusts through silently, water runs down the chimney pipe, and the first sign is a tan stain on the master bedroom ceiling. That’s a Gelco-specific failure mode amplified by Plano’s climate: humid summers accelerate rust, mild winters with an occasional freeze stress the metal, and infrequent burning means nobody notices until water intrusion is the symptom. If you live in a 1990s-era build off Legacy Drive or a 2000s home in Willow Bend, you own exactly the kind of Gelco system we’re describing. An annual inspection catches the rust before the stain. A repair after the stain costs more. We’d rather catch it early, and that’s what our Level 2 inspection is built for.
Gelco Models & Products We Service in Plano
We service the Gelco Thermo-Safe chimney, the Gelco SS II chimney, and the Gelco Ventinox chimney. Those are the three lines we see most often in Plano homes built between 1980 and 2010. For replacement parts, we recommend OEM Gelco components whenever possible. Aftermarket knock-offs sometimes have slightly different twist-lock tapers that don’t seat securely, especially on older units. That said, if a Gelco chase cover is rusted through beyond a simple patch and OEM stock is months out, we’ll honestly assess whether a fabricated stainless replacement will outlast the rest of the chimney. If it won’t, we’ll say so before charging for a repair. We stock common caps, chase covers, and joint sealants locally for fast turnaround in the Plano area.

AfterGelco Service Pricing in Plano
Most Plano Chimney Sweep services run between $189 and $300, depending on the type of system and its condition. A Level 2 inspection on a Gelco gas fireplace usually runs between $350 and $500 because it includes camera work up the flue and a close look at the chase cover and flashing. Cap replacements and chase cover fabrications are priced by the job, and you’ll get a written price before any work starts. The number on the invoice matches the number we quoted at the door. That’s been the rule since 2002, and it’s been Nathan’s rule longer than that. Call (361) 314-3193 for a free estimate on your Gelco chimney in Plano.

FAQs – Gelco Chimney Cleaning in Plano
Yes, and this is the most common Gelco repair we handle in Plano. The factory chase cover rusts through, water gets inside, and the firebox and ceiling show the damage. We remove the old cover, fabricate a heavier-gauge stainless replacement, seal the pipe penetration, and install a proper cap. The repair is covered by our written guarantee. Call (361) 314-3193 for a free inspection.
It includes a camera run up the full flue, a check of the twist-lock joints for separation, an inspection of the chase cover and roof flashing, and a look at the interior liner for warping or cracking. On a Plano gas fireplace that’s never been burned, we’re mainly looking for water intrusion points and animal entry. If you’re buying or selling a home, this is the Plano Chimney Inspection you want in writing.
We use OEM Gelco parts whenever they’re available. The twist-lock tapers on Gelco sections are precise, and aftermarket parts sometimes don’t seat securely. For rusted chase covers, a fabricated stainless replacement often outlasts the original. We’ll tell you which makes sense for your specific chimney before you pay anything.
Yes. We remove the nest, inspect the flue and joints for damage, and install a cap that keeps animals out going forward. In Plano, unused Gelco flues are prime nesting spots because nothing ever disturbs them. The nest has to come out before any cleaning or inspection means anything.
Once a year is the honest answer, even if you never burn wood. Plano’s humidity causes rust, and the occasional winter freeze stresses the joints. An annual inspection catches a rusted chase cover before it leaks. If we find an issue, you’ll get a written quote right then. Call (361) 314-3193 to schedule.
