Gelco Chimney Cleaning in The Hills, TX | Resolute Chimney Sweep
We provide independent Gelco chimney cleaning and repair across The Hills, including 78738. The one thing that sets our Gelco work apart here is that we sweep the outdoor fireplace flues as carefully as the indoor ones. Most houses in The Hills lean hard on their covered-patio limestone fireplaces, so the exterior flue is usually the dirtiest one on the property. Call (877) 644-8036 for a free estimate on any Gelco unit.
Why The Hills Residents Choose Us for Gelco Service
We’ve been sweeping and repairing Gelco fireplaces across The Hills’ custom limestone homes long enough to know how their dampers, fireboxes, and multi-flue tops actually wear in this climate. Brent Calloway, our owner and lead technician, spent his technical foundation at Temple College, working through building systems and mechanical trades coursework that still shapes how he approaches every flue liner and burner set we touch. He’s been doing chimney and vent work in the Georgetown area for well over a decade. The Hills jobs are a particular kind of project: big, designer masonry fireplaces where the homeowner expects detail-oriented work on expensive stonework. We bring that. We’re an independent Gelco service provider, not factory-authorized, which means we recommend what’s right for your firebox, not what a manufacturer program tells us to push.

Common Gelco Chimney Cleaning Problems We Solve in The Hills
Gelco units hold up well, but The Hills’ specific conditions create a predictable set of failure points. Here’s what we find most often:
- Gas-log and gas-insert burners gone lazy after idle months. Central Texas summers leave great-room fireplaces untouched for six months or more. Dust settles into Gelco burner ports, spiders set up inside the valve area, and the first light-up of fall produces a weak yellow flame instead of a clean blue one. We pull the logs, blow out the ports, and reset the burner for even ignition.
- Outdoor limestone fireplace flues packed with soot and mud dauber nests. In The Hills, the covered-patio fireplace gets used far more than the indoor one, but swept far less often. Exterior flues fill with soot, spider webs, and mud dauber nests that choke draft and can push smoke back under the patio. This is the number one Gelco-related issue we see in 78738.
- Dampers and firebox mortar cracked from heat-cool cycling. The Hills sees rare hard freezes followed by long hot dry stretches. That thermal swing makes Gelco damper frames and mortar joints spall and crack faster than in milder climates. A cracked damper lets conditioned air escape year-round and lets rain in during storms.
- Multi-flue caps and spark arrestors loaded with oak pollen and cedar. Pollen season in The Hills coats every outdoor surface, and Gelco multi-flue caps are no exception. When the mesh loads up, draft drops and the fireplace starts pushing smoke inside. It also creates a nesting spot for birds and wasps during idle months.
- Glass-door and screen enclosure sets misaligned or binding. Heat expansion on large custom fireplaces in The Hills slowly warps Gelco door frames and hinge points. The doors still close, but they bind or leave gaps that pull smoke into the room. We align and reseat them during the sweep whenever we can.
Gelco Service in The Hills: What Local Conditions Mean for Your Equipment
Here’s the thing about The Hills that most sweep services never think about: the outdoor limestone fireplace under the covered patio is the workhorse of the property, and it’s almost never the one that gets serviced. Homeowners schedule cleaning for the indoor great-room fireplace before winter, skip the exterior flue entirely, and then wonder why the patio fills with smoke on a Friday night in November. Because these outdoor boxes sit idle through the cedar and oak pollen season, then get fired up for entertaining season, they accumulate an entirely different kind of buildup than indoor flues: hardened creosote mixed with soot, dust dauber casings, and pollen compressed into the flue liner. A Gelco multi-flue cap on an outdoor fireplace in The Hills can lose half its draft capacity in a single spring. We see it on custom homes throughout the area every year. The chimney doesn’t care how long it’s been since the last cleaning, but the creosote does. That’s why we ask every The Hills customer two questions: how often do you use the outdoor fireplace, and when did that flue last get swept?
Gelco Models & Products We Service in The Hills
Our team works on the full range of Gelco residential equipment found in The Hills homes: wood-burning masonry fireboxes with heat-circulating grate assemblies, gas-log and gas-insert burner sets, multi-flue chimney caps and spark arrestors, and glass-door and screen enclosure sets. We fit OEM Gelco parts where they’re available, and quality aftermarket equivalents where OEM is discontinued or priced beyond reason. We’ll tell you which is which before any work starts. For The Hills turnaround, we keep common Gelco cap meshes, screen clips, and damper components on the truck, which means most cleaning visits end with the fireplace ready to use that evening. You can read more about how we approach the brand on our Gelco sales & service page.

FAQs – Gelco Chimney Cleaning in The Hills
No, we’re an independent service provider. We work on Gelco fireplaces, gas logs, caps, and doors throughout The Hills and nearby communities like Gelco in Briarcliff, but we have no factory affiliation or authorization. That independence means we repair or replace based on what’s best for your fireplace, not a corporate program. If a part is worth repairing, we say so. If it’s shot, we tell you that too.
We fit OEM Gelco parts where they’re available and where they make sense. When Gelco has discontinued a part or the OEM price is inflated for what it is, we’ll recommend a quality aftermarket equivalent and explain the difference before we order anything. You always know what’s going into your fireplace.
Most single-flue Gelco sweeps and inspections in The Hills and Gelco service in Barton Creek take 45 to 90 minutes. If we’re doing both the indoor fireplace and the outdoor limestone flue under the covered patio, plan on two hours total. Gas-log burner cleaning adds 20 to 30 minutes depending on how clogged the ports are.
A cracked mortar joint or a spalled damper frame is almost always repairable. A firebox with deep structural cracks, a warped floor, or refractory panels that have pulled away from the firebrick is a rebuild situation. In The Hills and surrounding areas like Gelco service in Hudson Bend, where most Gelco fireboxes are built into high-value custom masonry, we lean toward repair whenever it’s safe. You’ll get our honest read after the inspection, with photos showing exactly what we found.
Standard Gelco sweeping runs $195 to $345 for the indoor flue. Exterior fireplace flues run $75 to $125 more when done on the same trip. Gas-log burner cleaning adds $90 to $175. For an exact quote on your specific fireplace, call (877) 644-8036 and we’ll schedule the free estimate.
