Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Why Cedar Park Homeowners Choose Gelco Chimney Cleaning
Ashton Chimney provides independent Gelco service in Cedar Park: chimney cleaning, inspection, and repair throughout the area. We service the full Gelco line including Ultimate Series, Designer Series, Heat-Circulating Mark models, and gas inserts. We’re not affiliated with or authorized by Gelco, but our technicians know these fireplaces from the firebox up, which means we catch the creosote traps and damper weaknesses generic sweeps miss. Call (855) 507-9184 for a free estimate.

Cedar Park’s housing stock explains a lot about what we see in Gelco fireplaces here. Most of the city was built out between the 1990s and 2010s, when builders put fireplaces in as a selling feature rather than a daily heating source. That means thousands of Gelco units have sat mostly unused for years, and disuse creates its own set of problems. We routinely find rusted damper assemblies, spalled firebrick from occasional hard-freeze fires, and creosote that formed after one or two poorly drafted burns. Nolan Pruett, our owner, grew up in Buttercup Creek and has been providing Gelco service in Brushy Creek and Cedar Park for going on fifteen years. He knows which subdivisions have the builder-grade Gelco units, which older pockets near the original town center have masonry conversions, and what each tends to need.
What separates a brand-aware Gelco service from a generic sweep is simple. We know the airflow characteristics of Gelco’s baffle design. We know where the smoke chamber collects creosote on an Ultimate Series unit. We know which Mark-series dampers are prone to pivot-pin failure. That knowledge means fewer return visits and a cleaner burn the first time.
Key Takeaways:
- Independent Gelco service for all Cedar Park neighborhoods, including Buttercup Creek, Cypress Creek, and the Ranch at Brushy Creek
- Gelco-specific diagnosis based on the unit’s actual baffle, damper, and firebox design
- OEM Gelco parts sourced when available; quality aftermarket equivalents for discontinued models
- Free estimates by phone at (855) 507-9184
Why Trust Ashton Chimney for Your Gelco Chimney Cleaning?
Trust comes down to whether the person on your roof actually understands the appliance in your living room. Our techs have spent hundreds of hours inside Gelco fireboxes across the Austin metro, including Gelco in Anderson Mill and Cedar Park in particular. We know the Ultimate Series has a baffle that looks straightforward but creates a secondary creosote shelf in the smoke chamber when the damper is run partially closed. We know the Mark-series heat-circulating units have damper pivot pins that rust and bind in Cedar Park’s humid summers. We know the Designer Series units with custom surrounds often hide water intrusion behind the facade until it’s already damaged the firebox floor.
Nolan Pruett built that knowledge the slow way. He came up through the Building Trades program at Austin Community College’s Round Rock Campus, then spent his twenties working fireplaces and flues across the metro before settling back in his hometown. His wife will tell you he talks about creosote at the dinner table more than any reasonable person should. He considers that a compliment. The point is, when a Gelco unit in Cedar Park has a problem, we’ve usually seen that exact problem before, and we know what caused it.
We also respect the fact that you didn’t buy a Gelco fireplace expecting to think about it much. So we explain what we find in plain language, show you photos from the inspection, and give you straight options. Tell me what your fireplace is doing and I’ll tell you exactly what’s going on in that flue. That’s how Nolan puts it, and it’s how we work.

Common Gelco Chimney Cleaning Problems We Fix in Cedar Park
Every fireplace line has its own personality, and Gelco units have a few recurring habits we see across Cedar Park homes and in Gelco service in Jollyville.
- Creosote buildup in the smoke chamber, especially on Ultimate Series units. Gelco’s baffle design works well when the damper is fully open and the fire is hot. But if a homeowner runs the damper partially closed to slow the burn, airflow drops and creosote condenses on the smoke chamber walls faster than the flue can carry it away. We find thick, shiny deposits in exactly that spot on Ultimate Series fireplaces that have been used for a few seasons without a sweep.
- Rusted or warped damper blades and seized pivot pins. Cedar Park’s long humid summers are rough on exposed steel. When a fireplace sits unused from April to November, moisture settles on the damper assembly. The blade warps or the pivot pins rust, and suddenly the damper won’t seal or won’t move at all. This is the most common Gelco issue we repair in this area, bar none.
- Cracked and spalling firebrick in the firebox. Gelco fireboxes are built to handle heat, but not necessarily the combination of heat and moisture that Cedar Park throws at them. After a hard freeze, a homeowner lights a fire, the firebrick heats quickly, and any moisture trapped in the masonry expands. Hairline cracks turn into spalled faces and loose mortar joints. Left alone, the firebox floor starts failing.
- Loose or missing rain caps and deteriorated crown seals. A lot of pre-fab Gelco chimneys in Cedar Park have standard issue rain caps that loosen over time. Add freeze-thaw cycles to the crown seal, and suddenly water is running down the inside of the flue. By the time the homeowner notices rust streaks on the firebox walls, the crown has been leaking for months.
- Slow-moving or non-functional insert fans on gas conversion units. On Gelco gas inserts, the blower fan can run but push barely any heat. It’s rarely the motor itself. More often, the fan cavity is packed with lint and dust, or the heat exchanger passages are blocked. A creosote problem this is not, but a service call it definitely is.
Gelco Parts & Our Repair-vs-Replace Approach
We source OEM Gelco dampers, firebrick, and rain caps whenever the manufacturer still supplies them. For discontinued models, including several Mark-series units we see regularly in Cedar Park, OEM parts simply aren’t available. In those cases we carry aftermarket equivalents that meet or exceed the original specs. We’ll tell you which is which before we do any work, because you deserve to know exactly what’s going into your fireplace.

Our stance on repair versus replace is straightforward. If the firebox is structurally sound and the flue liner is intact, we repair. A new damper assembly, fresh firebrick, a proper crown seal: those are all repairs we can do in a single visit, and there’s no reason to replace a whole unit over them. But if we find a cracked flue tile, a rusted-through smoke chamber, or a firebox that’s lost its structural integrity, we’ll show you the camera footage and give you an honest recommendation. Sometimes that recommendation is a full liner replacement or a new unit. Sometimes it’s a repair that buys you five more years. We’ll tell you what we found, what it means, and what your options are, in plain language. Call (855) 507-9184 and we’ll start with the inspection.
Our Gelco Service Process – Step by Step
- 1
Diagnosis. We start with a visual inspection of the firebox, damper assembly, smoke chamber, flue, and crown. For any Gelco unit showing water damage, drafting issues, or creosote beyond a light dusting, we recommend a Level 2 camera inspection. That camera run is where we find the stuff you can’t see from the living room floor.
- 2
Repair or cleaning. If it’s a cleaning, we use rotary poly brushes sized to your Gelco flue, and we pay special attention to the smoke chamber where Gelco’s baffle design traps creosote. If it’s a repair, we install the OEM or aftermarket part we agreed on, and nothing goes in without your sign-off.
- 3
Test. After the work is done, we fire the unit and check the draft. We check the damper operation, the fan function on gas inserts, and we’ll put a smoke test on the flue if anything looked questionable during the camera run. You don’t get a handshake and a maybe. You get a working fireplace.
- 4
Documentation. We hand you a written report of what we found and what we did, including photos and camera stills where applicable. If you’re a property manager, that report goes to your file. If our work carries a manufacturer warranty on the parts, we walk you through that paperwork before we leave.

AfterGelco Products We Service & Install in Cedar Park
We service and repair the full Gelco lineup you’re likely to find in a Cedar Park home. That includes the Ultimate Series wood-burning fireplace, the Designer Series, and the Heat-Circulating Series including Mark-series models from the older production runs. We also work on Gelco gas fireplace inserts, which in this area are often DIY conversion units added to builder fireplaces. For parts, we keep common damper assemblies, firebrick, rain caps, and door gaskets on the truck for Gelco and other brands so we aren’t burning your afternoon waiting on a supply house. If it’s a discontinued Mark-series part, we’ll tell you upfront and source the aftermarket equivalent.
We Also Service These Brands
Gelco isn’t the only name we know cold. We install and service DuraFlex stainless liner systems for wood and gas applications, and we’re HeatShield-certified for flue resurfacing when a full liner replacement isn’t necessary. If you have a mixed-brand chimney system, which a lot of Cedar Park homes do after a gas conversion, one call covers all of it.
FAQs – Gelco Chimney Cleaning Service in Cedar Park
That smell is almost always a creosote deposit in the smoke chamber drawing moisture and off-gassing into the room, or a damper that isn’t sealing against the flue and letting air backdraft down the chimney. Gelco’s baffle design means creosote collects in the smoke chamber more readily than on a straight-flue masonry fireplace, and Cedar Park’s humidity makes that deposit smell worse. The fix is a full sweep with attention to the smoke chamber, plus a damper check. Call (855) 507-9184 to schedule an inspection.
Yes, with a caveat. Original OEM damper assemblies and firebrick for the Mark series are no longer manufactured, but we carry aftermarket equivalents that match or exceed the original specifications. For most Mark-series units, that means a replacement damper blade and pivot pin assembly, and standard firebrick in the original dimensions. Before we order anything, we’ll show you what’s available and what it costs.
A Level 1 inspection is a visual check of the accessible parts of your fireplace and flue: firebox, damper, smoke chamber, and what’s visible from the top. It’s appropriate for a unit that’s been regularly swept and isn’t showing problems. A Level 2 inspection adds a camera run down the full flue and is what we recommend for any Gelco unit that’s been exposed to water intrusion, a chimney fire, a hard freeze, or hasn’t been inspected in years. Level 2 is also what most property transactions and insurance claims require. We’ll tell you which one your situation calls for.
No, that’s a ventilation and airflow issue, not a creosote one. On Gelco gas inserts, the blower fan pulls room air through the heat exchanger cavity. If that cavity is packed with dust, pet hair, or lint, the air never picks up the heat from the firebox, so you get a spinning fan and lukewarm air. We open the unit, clear the fan cavity and heat exchanger passages, and the thing usually returns to full heat output. It’s a common service call in Cedar Park, especially in homes with pets.
If you burn a fire more than a few times a season, sweep it once a year before the first burn of fall. If you only light it once or twice a year after a hard freeze, every two to three years is usually enough, but the inspection matters more than the sweep. Cedar Park’s idle months cause rust, pests, and water intrusion even when you aren’t burning. The annual visual inspection catches those before they become a cracked firebox or a failed damper. Call (855) 507-9184 to get on the fall schedule before the first freeze surge fills the calendar.
No. We are an independent Gelco service provider. We are not a Gelco authorized dealer or warranty station, and we do not claim manufacturer authorization. What we are is familiar with the product line at a level that comes from years of hands-on work with Gelco units in Cedar Park homes. We source OEM parts where the manufacturer still supplies them, and we recommend aftermarket equivalents when OEM is discontinued. Our independence means our recommendations are about what’s best for your fireplace, not what a manufacturer’s authorized network tells us to say. Call us at (855) 507-9184 for a straight answer on your Gelco unit.

Last winter we were called to a Gelco Ultimate Series fireplace in Cedar Park where the homeowner had been burning unseasoned oak and noticed smoke rolling into the room. Our tech found a third-degree creosote glaze on the flue walls and a warped damper blade that wouldn’t close properly. We performed a full sweep with rotary poly brushes, removed the glazed creosote, and replaced the damper with an OEM-spec unit, restoring a safe, clean burn. If that sounds familiar, call us at (855) 507-9184 for a free estimate. We’ll send a Gelco-trained tech, not a generic sweep.
