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 Marietta Homeowners Choose Gelco Chimney Cleaning
Marietta Gelco service means removing creosote (the flammable tar buildup that makes chimneys a fire risk) from stainless liners and caps that behave differently than clay tile or prefab pipe. We’re an independent Gelco service provider, not a manufacturer-authorized outlet, and we service the full range of Gelco rigid and flex liners, multi-flue caps, and top-mounted dampers across Cobb County. What sets our Gelco work apart is the depth of field experience: we know where these components fail in Marietta’s humid, pollen-heavy climate, and we document every finding with photos before recommending any repair. Call (762) 249-4619 for a written quote on Gelco chimney cleaning, cap replacement, or damper repair.
Gelco makes solid stainless components. But “solid” doesn’t mean “maintenance-free,” and Marietta’s specific conditions, pine needles, oak pollen, summer humidity, winter freeze-thaw cycles, put real stress on liner walls, cap screens, and damper gaskets. We clean and repair enough Gelco systems each year, including Gelco repair in Mableton, to know exactly what fails, why it fails, and whether a part can be saved or should be replaced.
Why Trust Hadley Chimney Marietta for Your Gelco Chimney Cleaning?
Cory Mitchell, our owner, picked up his trade fundamentals at Los Angeles Trade-Technical College before spending the better part of two decades working chimneys across the Southeast. He and the crew have been servicing Marietta homes for years, from newer builds near Kennesaw Mountain to older craftsman houses where the liner hasn’t been touched in thirty years. Cory’s rule is simple: “I’ll send you the photo first, then we’ll talk about what it means.” That’s how every Gelco job runs at Hadley Chimney Marietta. You see what the tech sees, with a written price before any work starts, and a full photo report when the job is done.
Our technicians work with Gelco components weekly, so they recognize the difference between a liner that needs mechanical creosote removal and one that has corroded past the point of safe service. We prioritize Genuine Gelco replacement parts for caps, dampers, and liner accessories because fit matters and a slightly-off aftermarket part can compromise draft or leak. Every repair carries our 365-Day Done Right Promise: a written guarantee on every repair and a free second visit if the repair fails. That’s a standing commitment, not a promotional offer.
Hadley Chimney Marietta operates under The Relay Visibility Guarantee as part of the Relay Home Co. family. Live arrival tracking, before-and-after photo documentation, digital invoicing, and a written price before work begins on every job, including Gelco cleanings and repairs. A real person answers the phone 24/7 at (762) 249-4619.

Common Gelco Chimney Cleaning Problems We Fix in Marietta
- Stage-two creosote glaze in corrugated rigid liners. Gelco 5.5-inch Round Stainless Chimney Liners have corrugated interior walls that create micro-ledges where creosote accumulates faster than on smooth-wall pipe. In Marietta’s humidity, that creosote absorbs moisture and hardens into a shiny, tar-like glaze. Standard wire brushing won’t remove stage-two glaze. We use mechanical whip systems and chemical treatments to break it down without damaging the stainless walls.
- Galvanic corrosion at cap-to-flue-tile connection points. Gelco stainless caps are excellent, but when they’re mounted directly against clay flue tile with a dissimilar metal fastener, Marietta’s summer thunderstorms create the electrolyte environment for galvanic corrosion. We regularly see pitting at the cap base and bolt holes. Left unchecked, the cap loosens, shifts, and eventually fails. During cleaning we pull the cap, inspect the contact points, and replace corroded hardware before it becomes a structural problem.
- Pine needle and oak pollen clogged cap screens. Marietta’s tree cover is dense, and Gelco Multi-Flue Chimney Caps and Deluxe Rain Caps with Screen have fine mesh designed to keep out animals and embers. That mesh also traps pine straw and oak pollen. When the screen clogs, draft drops and smoke rolls back into the living space. This is one of the most common Gelco issues we fix in neighborhoods with heavy tree canopy around the historic Square and along Whitlock Avenue. The fix is straightforward: remove the cap, deep-clean or replace the screen, and confirm draft before reinstalling.
- Hardened silicone gaskets on top-mounted dampers. Gelco top-mounted dampers use a silicone gasket to seal against the flue opening. Marietta’s freeze-thaw cycles and summer heat cause that gasket to harden and crack over time. A failed gasket lets conditioned air escape in summer and chimney odors enter the home in winter. We stock Genuine Gelco damper gaskets on the truck and can usually replace one on the same visit.
- Narrow flue restrictions from creosote and debris accumulation. Homes in Marietta’s older districts often have chimney systems retrofitted with Gelco flex liners decades ago. We find Gelco 6-inch Oval Flex Chimney Liners in historical conversions where the original flue was uneven or undersized. These oval liners develop creosote pockets at the transition points and need targeted cleaning with rotary whip systems rather than standard square brushes. We clean them carefully to avoid pushing debris into the connector or smoke shelf.
Gelco Parts & Our Repair-vs-Replace Approach
We’d rather clean or repair a Gelco part than sell you a replacement. That’s just the honest math: a damper gasket replacement costs a fraction of a new damper, and a cap screen can often be cleaned and reused if the stainless frame is solid. But we won’t stretch a part’s life beyond what’s safe or cost-effective, and we’ll tell you when replacement is the better long-term choice.
Genuine Gelco components are our default for caps, dampers, and liner accessories. OEM parts fit exactly and match the original material specifications, which matters for corrosion resistance and draft performance. For high-wear items like rain caps, we’ll sometimes recommend a quality aftermarket equivalent with better corrosion resistance for Marietta’s humidity, but only when it’s a demonstrable upgrade, not a cost-cutting shortcut. If we recommend aftermarket, we’ll tell you why and back it with the same 365-Day Done Right Promise.
We keep common Gelco replacement parts on the truck, including damper gaskets, cap screens, and stainless fasteners. That means most Gelco repairs are completed during the first visit. Call (762) 249-4619 if you’d like an exact quote for your Gelco system.
Our Gelco Service Process – Step by Step
- 1
Diagnosis and camera inspection. Before any cleaning or repair, we inspect your Gelco liner, cap, and damper. We run a camera up the flue to document creosote type and depth, check cap screens for clogging or corrosion, and test damper gasket seal. You get the photos. If the camera shows a problem, you see it.
- 2
Cleaning and component-specific repair. For Gelco rigid and flex liners, we choose the cleaning method based on what the camera showed: standard brushing for stage-one creosote, rotary whip for stage-two glaze, or chemical treatment for particularly tenacious buildup. If we find a failed damper gasket, corroded cap hardware, or a torn screen, we repair or replace those components using Genuine Gelco parts or a clearly explained aftermarket upgrade.
- 3
Draft and function testing. After cleaning and repairs, we check draft at the fireplace or appliance opening and confirm smoke evacuates cleanly. We also inspect the cap from the roof, testing for stable mounting and proper screen condition.
- 4
Photo report and written warranty. You get before-and-after photos of everything we touched, a written price breakdown, and a written guarantee on every repair through our 365-Day Done Right Promise. If a repair fails within 365 days, the second visit is free.

FAQs – Gelco Chimney Cleaning Service in Marietta
Yes, but it requires more than a standard wire brush. The corrugated interior walls of Gelco rigid liners trap creosote in the grooves, and in Marietta’s humidity that creosote often hardens into stage-two glaze. We use rotary whip systems with flexible polymer heads to work the creosote out of the corrugations without scratching or denting the stainless. If the camera inspection shows stage-three creosote, we may recommend a chemical treatment or liner replacement, but we’ll show you the photos before recommending anything.
Usually yes, if the corrosion is caught early. The rust you’re seeing is galvanic corrosion from dissimilar metals at the bolt contact points, accelerated by Marietta’s thunderstorms and humidity. If the pitting is limited to the hardware, we replace the fasteners with stainless and add a non-conductive barrier to prevent further reaction. If corrosion has eaten into the cap base itself, the structural integrity is compromised and replacement is the safer call. We’ll show you the close-up photos and give you a straight recommendation.
At minimum once per year for wood-burning systems, and more often if you burn frequently or notice smoke rollout. Marietta’s high humidity accelerates creosote hardening, and the area’s pine and oak canopy means more debris enters the flue. If you burn three or more cords per season or your fires are slow-burning, schedule twice-yearly cleanings. The cost of our Chimney Sweep services is small compared to the cost of a chimney fire or liner replacement. Call (762) 249-4619 for an exact quote.
Yes. We stock Genuine Gelco replacement damper gaskets on our trucks, so most top-mounted damper gasket failures are repaired the same visit. Silicone gaskets harden and crack over time in Marietta’s climate, and a failed gasket means air leaks and chimney odors. We can replace the gasket, test the seal, and confirm the damper operates correctly before we leave.
Clogged screens can almost always be cleaned and reused. We remove the cap, clear the pine straw and creosote from the mesh, and test airflow. A torn screen is a different situation: if tears are small, we can sometimes patch with stainless mesh, but if the damage is extensive or the screen frame is corroded, replacement is the better investment. We’ll show you photos of the screen condition and give you the repair versus replace math before any work starts.
Gelco chimney cleaning in Marietta typically runs $189 to $349 depending on liner type, creosote stage, and whether cap removal or damper service is included. Stage-two glaze removal and mechanical whipping adds cost because of the extra labor and equipment involved. Cap screen cleaning is often included with a standard sweep, but cap replacement or damper gasket replacement are quoted separately. You’ll always get a written price before work begins, with no surprises at the door. Call (762) 249-4619 for a free estimate based on your specific Gelco system.
