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 Dallas, GA | Ashby Chimney Marietta
A Dallas Chimney Sweep for your Gelco costs between $189 and $329, depending on creosote buildup and damper condition. Ashby Chimney Marietta provides independent Gelco service across Dallas, GA, and the one thing that makes our work here different is that we know the sticky, tar-like glaze this city’s humidity produces. Most crews just brush; we usually have to chip. Call (478) 796-8742 for a free estimate.
We’ve worked on Gelco GC, GS, and GX Series chimneys throughout Dallas since 2002. Nathan Corliss leads our crew, and he’s spent twenty-two years learning what factory-built systems do in Georgia’s particular blend of heat and moisture. If you own a Gelco in Dallas, you’re dealing with a specific set of problems a generic sweep won’t catch. We catch them every day. This page covers what we see, what it costs, and how we fix it.
Why Dallas Residents Choose Us for Gelco Service
Gelco factory-built chimneys show up all over Dallas, from Seven Hills to the subdivisions off Merchants Drive. Homeowners call us because we know these units inside and out. The GC Series, GS Series, and GX Series each have their own quirks. A Gelco GC Series from the late 1980s handles moisture differently than a GS Series from 2003. Most chimney companies treat them all the same. That’s how a simple cleaning turns into a missed problem.
Nathan grew up in Los Angeles and picked up his trade fundamentals at Los Angeles Trade-Technical College before chimney work pulled him into a career he hasn’t left for twenty-two years. He’s covered a lot of metropolitan Atlanta, including plenty of older houses near Kennesaw Mountain with flues that demand a steady hand and an honest eye. When our crew arrives in Dallas, we arrive knowing what we’re looking at. We carry OEM Gelco parts where they matter most, and we put every price in writing before we touch a brush. That’s been our way since 2002, and it’s why homeowners in Dallas keep calling us back.

Common Gelco Chimney Cleaning Problems We Solve in Dallas
- Sticky, tar-like creosote glaze. Dallas summers bring thunderstorms, and a lot of older Gelco installations never got rain caps. Water mixes with creosote and forms a corrosive glaze that standard brushes won’t remove. We chip it away by hand, which takes longer but actually gets the flue clean.
- Deteriorated mortar joints on 1970s-1990s Gelco builds. Humid air works its way into mortar over decades. In Dallas, we regularly see mortar joints on Gelco chimneys that look solid from the ground but crumble the moment we touch them. We repoint before the brick starts to shift.
- Warped or rusted dampers. Gelco dampers sit right at the top of the firebox, exposed to every bit of humidity that rolls through. Rusted dampers don’t seal, which means cold air in winter and, in Dallas, sticky damp air all spring. We repair or replace them with OEM Gelco dampers when they’re available.
- Cracked flue tiles from thermal shock. Dallas winters are mild, so fireplaces get used occasionally, not steadily. Homeowners let the firebox sit cold for a month, then build a big fire. The rapid temperature swing can crack Gelco flue tiles. We spot these cracks early during a cleaning, before they become a repair.
- Leaky chimney caps or missing caps entirely. A surprising number of Gelco chimneys in older Dallas subdivisions never had caps installed. Every summer thunderstorm sends water straight down the flue. We install custom caps on Gelco units, and it’s the single most effective thing most Dallas homeowners can do to extend chimney life.
Gelco Service in Dallas: What Local Conditions Mean for Your Equipment
Here’s what we see in Dallas that we don’t see with the same frequency in Marietta or Kennesaw. Dallas sits squarely in a humid subtropical climate, and that means winter fires happen, but not every night. The fireplace gets lit on a cold December weekend, then sits unused for two weeks. That intermittent burn cycle creates creosote, yes, but it’s different from the creosote in a house where someone burns a fire every day. In Dallas, the creosote has time to absorb moisture between uses. When a summer thunderstorm rolls through and the chimney has no rain cap, water pours onto that creosote and bakes it into a hard, tar-like glaze. Brushing won’t touch it. We bring scrapers and chipping rods designed for exactly this build-up. A Gelco owner in Dallas needs a sweep who understands glaze, not just soot. That’s the difference between a cleaning that lasts two seasons and one that lasts two months.
Gelco Models & Products We Service in Dallas
We service the full Gelco range in Dallas: the GC Series, GS Series, and GX Series. That includes original installs from the 1970s through recent builds. For anything structural or safety-critical, like dampers and chimney caps, we use OEM Gelco parts when they’re available. For non-structural items like certain covers or grates, we’ll recommend quality aftermarket parts that save you money without cutting corners. We keep common Gelco-compatible dampers, caps, and flue components in stock, so Dallas calls don’t require waiting on a shipment to finish the job.

AfterGelco Service Pricing in Dallas
A standard Gelco chimney cleaning in Dallas runs $189 to $329. If we’re dealing with heavy tar glaze, that’s on the higher end because the labor is different. Adding a custom rain cap typically falls between $150 and $400 installed, depending on the flue size and whether the Gelco crown needs prep work. Mortar repointing runs $20 to $35 per square foot. Every estimate is free and we give you a written price before any work starts, so the invoice matches what we quoted. Call (478) 796-8742 and we’ll tell you what your specific Gelco needs.

FAQs – Gelco Chimney Cleaning in Dallas
Dallas’s humidity causes two Gelco-specific problems: creosote absorbs moisture and turns into a hard glaze that’s difficult to remove, and mortar joints absorb water, weakening over time until the brick starts to shift. Our Chimney Inspection in Dallas catches both before they get expensive. Call (478) 796-8742 to schedule a free estimate.
Yes, and in Dallas, it’s the first thing we recommend for any Gelco unit without one. A custom cap keeps summer thunderstorms out of the flue, which prevents the tar-like glaze we spend so much time chipping away. Ours are fitted to the Gelco flue dimensions, not a one-size-fits-all cap from a box store.
Yes. We repair or replace Gelco dampers regularly in Dallas. Rust from humidity is the most common culprit, and a damper that doesn’t seal lets cold air in during winter and damp air in during summer. We use OEM Gelco dampers when available. Call (478) 796-8742 and we can walk you through what yours likely needs.
Crumbling mortar on a Gelco chimney in Dallas is almost always moisture intrusion. Decades of humid air and the occasional driving rain work into the joints, and the freeze-thaw cycle, mild as it is here, eventually breaks them down. Repointing fixes it, but it works best before brick starts shifting. We repoint Gelco chimneys throughout Dallas, and we’ll show you photos before we recommend it.
Once a year if you burn more than a cord of wood, or every two seasons if the fireplace is mostly decorative. In Dallas, the risk isn’t a roaring chimney fire; it’s the humid months turning whatever creosote is there into glaze that’s harder to remove next time. The cheaper cleaning is always the one that happens before the glaze forms. Call (478) 796-8742 and we’ll help you set the right interval for your Gelco.
