Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Keller, TX | Hadley Chimney Fort Worth
We provide independent Keller Chimney Sweep and repair across Keller, and here’s the short version: if your home was built between roughly 1995 and 2015, there’s a solid chance you’ve got a Gelco prefab chimney that’s never been properly inspected. Our crews know the exact rust, damper, and creosote patterns these systems develop in Keller’s climate, and we fix them with OEM or better parts. Call (682) 900-6393 for a free estimate, and we’ll send a background-checked tech who won’t leave you guessing about what’s actually wrong.
Why Keller Residents Choose Us for Gelco Service
Most chimney sweeps can run a brush up a flue. Far fewer can tell you, before they even get on the roof, that your Gelco damper is probably frozen from years of North Texas humidity and temperature swings. That’s the difference field time makes. Cory Mitchell, who leads our Fort Worth crew, picked up his trade fundamentals at Los Angeles Trade-Technical College and has spent two decades inside fireboxes and flue systems across the country. Around here, that means older brick fireplaces near the TCU campus and a lot of builder-installed Gelco prefab units in Keller’s newer subdivisions. We know what a 20-year-old galvanized flue looks like from the inside, and we’ll show you the photos before we ever hand you a price. We’re proud of that. It’s the same reason we stock OEM-compatible Gelco parts for common failures and can often complete a Chimney Repair in Keller or cap replacement in one visit.

Common Gelco Chimney Cleaning Problems We Solve in Keller
- Rusted-through galvanized flue panels: Keller’s humidity and occasional ice storms put moisture right where Gelco’s galvanized sheet metal meets years of acidic creosote. We regularly see seam rust that’s gone from cosmetic to structural in 15 to 20 years, especially on chimneys that were never swept after the builder handed over the keys.
- Seized factory dampers on Gelco prefab fireplaces: Keller’s temperature swings between hot summer days and freezing winter nights cause metal parts to expand and contract constantly. A damper that’s never been exercised rusts in place until it won’t budge. We see it on Gelco units in Hidden Lakes every single season.
- Loose or blown-off Gelco chimney caps: Ice storms in Keller push water into the flue and rust the mounting band, then a good wind gust finishes the job. A missing cap means rain, birds, and squirrels get in. We replace caps with proper Gelco or aftermarket stainless units that actually stay put.
- Crumbling refractory panels: These are the heat-resistant panels that line a Gelco firebox. Homeowners often dismiss hairline cracks as cosmetic, but a Level 2 inspection frequently finds heat has been working through the gaps into framing. In Keller, where fireplaces sit dormant for months, moisture accelerates the breakdown once cracking starts.
- Creosote buildup in never-serviced flues: Gelco prefab chimneys look maintenance-free, so Keller homeowners skip the sweep. The hard water and humidity here don’t help; creosote gets sticky and corrosive against metal flue walls faster than in drier climates. We remove it with rotary tools that won’t damage the liner.
Gelco Service in Keller: What Local Conditions Mean for Your Equipment
Here’s what we know from working Keller’s subdivisions that you won’t find in any Gelco manual. In Hidden Lakes and Marshall Ridge, the original builder-installed Gelco prefab chimneys from the 1990s and 2000s have mostly never been inspected. Not once. That means the first time a camera ever goes up the flue is when we arrive. When that happens, we expect rusted dampers and hairline corrosion on the flue interior, even in homes where the fireplace was barely used three times a year. The reason is straightforward: Keller’s humidity sits against that galvanized metal for months, and the creosote from even occasional fires becomes acidic enough to eat through the coating. You can’t see it from the outside, and the fireplace will light fine right up until it doesn’t. We would rather catch it before it gets to the “doesn’t” part.
Gelco Models & Products We Service in Keller
We work on Gelco galvanized metal flues, Gelco stainless steel flue liners, and Gelco prefabricated fireplace units. When the flue is otherwise sound, we use OEM Gelco parts where they’re still available. But many Keller homes have 20-year-old systems where patching a rusted galvanized section is just a short-term fix. In those cases, we’ll tell you straight that a quality aftermarket stainless liner or cap is the honest long-term move, and we’ll show you the camera footage to back it up. We stock the common Gelco replacement parts locally, which means faster turnaround for Keller repairs without waiting on a parts shipment to figure itself out.

FAQs – Gelco Chimney Cleaning in Keller
Look at the chimney from outside. If it’s a metal pipe sticking out of the roof, often with a cap, the fireplace below is almost certainly a prefab unit, and Gelco is one of the most common brands installed in Keller homes built from the 1990s through 2010s. If you can’t tell, we’ll identify it in the first five minutes of the visit, camera in hand.
Sometimes. If the rust is limited to the cap area or a single panel and the rest of the flue is sound, we can replace the damaged section. But once rust has worked its way along multiple seams, patching becomes a stopgap, and a stainless liner or fireplace replacement is usually the honest long-term fix for Keller homes with 20-year-old Gelco systems. Call (682) 900-6393 for a camera inspection to see which side of that line your flue is on.
Humidity does it. Keller’s damp air and seasons of disuse let moisture sit against the damper frame, rusting the metal. Then the first cold snap hits, you try to use the fireplace, and the thermal expansion of the flue components makes a rusted damper seize. We usually replace it with a top-sealing damper that actually closes tight and won’t freeze in place again.
For a builder-installed Gelco unit that’s never been inspected, absolutely. The Level 2 camera inspection is how we see rust-through, damaged refractory panels, and heat exposure that a brush sweep alone would miss. In Keller’s Hidden Lakes and Marshall Ridge, most original Gelco prefab chimneys have never been looked at since the home was built, so this is our standard first recommendation. The camera footage is yours to keep.
Every year, even if you don’t use the fireplace much. Keller’s humidity makes creosote sticky and corrosive against Gelco’s metal flue walls, so buildup matters more here than in drier parts of Texas. A yearly sweep catches rust and damper issues before they become structural. Call (682) 900-6393 to book your sweep; our techs will show you the before-and-after photos on the spot.
