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 Marietta, GA | Hadley Chimney Marietta
We provide independent Gelco chimney cleaning and repair across Marietta, from the historic neighborhoods around the Square to the 1980s subdivisions near Kennesaw Mountain. What makes our Gelco work different here comes down to one thing: Marietta’s humid summers and freeze-thaw winters demand a different cleaning approach than what works in drier parts of Georgia. Call (762) 249-4619 for a free estimate on any Gelco chimney, liner, or cap repair. Cory Mitchell and our Marietta crew know exactly how Gelco components hold up in this climate.
Why Marietta Residents Choose Us for Gelco Service
Gelco builds solid chimney products, but Marietta’s weather puts them through more than the manufacturer’s manual assumes. We’ve been working on Gelco installations in this city long enough - as your local Marietta Chimney Sweep - to know which liners glaze over in humid summers, which chase tops leak after a storm, and which caps loosen in the wind that funnels through older neighborhoods near the Square. Cory Mitchell learned his trade fundamentals at Los Angeles Trade-Technical College before spending nearly twenty years on real jobs across the Southeast, and he’s been working Marietta homes long enough to recognize a failing Gelco liner before it becomes a smoke backup.
We’re an independent service provider, not a factory-authorized dealer. That matters because we’re free to be honest about when a Gelco part can be repaired and when it genuinely needs replacement. We stock genuine Gelco replacement liners, caps, and chase tops, and for minor hardware and sealants we select premium aftermarket parts that meet or exceed Gelco specs. You get the right part without paying a brand premium on every screw and gasket. And every recommendation we make comes with a photo sent to your phone before we write anything up.

Common Gelco Chimney Cleaning Problems We Solve in Marietta
- Sticky creosote glaze in Gelco ProFlex liners. Marietta’s high humidity during summer months makes creosote build up as a sticky, tar-like glaze rather than flaky dry soot. Standard rotary brushes just smear it around. We use whip systems with specialized gel cleaners to break it down without scoring the stainless liner surface.
- Rust and corrosion on Gelco DuraVent rigid stainless sections. Homes built in the 1970s through 1990s across Marietta’s suburban subdivisions often have chase tops that leak silently. Water gets in, sits on the stainless sections, and corrosion follows. We find this constantly in neighborhoods like those off Powder Springs Road and Canton Road. The fix usually involves replacing the chase top, not just wire-brushing the rust.
- Brittle Gelco ceramic fiber insulation behind zero-clearance chimneys. Older zero-clearance units in Marietta attics with poor ventilation bake that insulation until it crumbles. You won’t see it from outside, but it reduces clearance safety. Our inspection includes the chase interior where most companies never look.
- Gelco multi-flue caps loosening in summer thunderstorm winds. Marietta gets real wind during afternoon thunderstorms, especially in older neighborhoods around the Square where chimney mass is taller and catches more of it. A loosened cap lets rain and pine needles into flues that were dry a month ago.
- Narrow flue obstructions in coal-to-wood conversions. In the Whitlock Avenue historic district, we routinely find Gelco liners installed inside flues that originally served coal fireplaces. These are narrow, winding, and nearly impossible to clean with standard brushes. Custom whip systems are the only way to do it without damaging the original brick or the liner itself.
Gelco Service in Marietta: What Local Conditions Mean for Your Equipment
If you own a home in Marietta’s Whitlock Avenue historic district, your chimney probably wasn’t built for wood. Many of these houses started with coal-burning fireplaces, and the flues are narrow and winding in ways you rarely see in newer Cobb County construction. When a Gelco liner gets installed in one of these old flues, standard cleaning brushes won’t follow the curves properly. They leave glaze behind, they can snag on the stainless corrugations, and they can’t reach the tight bends near the smoke shelf. We built our cleaning protocol around this Marietta-specific problem: custom whip systems sized to the actual flue diameter, run from both top and bottom when the design allows. It’s slower work, but it’s the only way to actually clean a Gelco liner in these converted flues without tearing out the original masonry. And for homeowners selling a Whitlock Avenue property, Marietta’s stricter code enforcement during resales means that documentation of a proper cleaning matters as much as the cleaning itself. We provide inspection reports that meet those property transfer requirements.
Gelco Models & Products We Service in Marietta
We work on the full Gelco residential lineup you’re likely to find in Marietta homes. That includes Gelco ProFlex stainless steel chimney liners, Gelco DuraVent rigid stainless flue sections, Gelco custom multi-flue chimney caps, and Gelco ZeroClearance prefabricated chimney chase tops. For cleaning, we use brushes and whip systems sized to each liner’s actual inner diameter, not a one-size-fits-all approach. For repairs, our rule is simple: if a Gelco liner is under ten years old and the steel is sound, we repair it. If the steel is heavily corroded or creosote has pitted the interior, we recommend replacement and show you the photos that justify it. We keep genuine Gelco caps and common DuraVent sections stocked locally so most Marietta repairs don’t wait on a shipment from a distributor.

FAQs – Gelco Chimney Cleaning in Marietta
Marietta’s summer humidity turns what would be dry, flaky creosote into a sticky tar glaze that bonds to the stainless steel corrugations of older Gelco liners. The standard rotary brush won’t remove it; it just compacts it. We use whip systems with gel-based cleaners that dissolve the glaze without scratching the liner. Call (762) 249-4619 to schedule a glaze removal, and we’ll send photos of the liner before and after.
Yes. We inspect the chase top and chase interior before cleaning, because cracked or corroded chase tops on 1980s zero-clearance units are common in Marietta and often leak water onto the Gelco sections below. If the chase top is sound, we proceed with cleaning. If it’s failing, we show you the photo and can arrange Chimney Repair in Marietta to replace it with a new Gelco chase top before debris and moisture do more damage.
We do, and we recommend it after any severe thunderstorm season. Summer storms with high wind are common in Marietta, and multi-flue Gelco caps can loosen on taller masonry chimneys near the Square. A loose cap lets rain and pine needles into flues that were clean the month before. We’ll check the cap’s fasteners and resecure or replace it as needed. A quick call to (762) 249-4619 gets you on the schedule.
We use custom whip systems sized to the actual interior diameter of the Gelco liner, because standard brushes cannot navigate the winding flues common in Marietta’s coal-to-wood conversions. In the Whitlock Avenue district especially, we see flues with tight bends that would snag a standard brush and leave glaze behind. The whip cleans the full interior without damaging either the liner or the original brick around it.
Most masonry chimneys in Marietta benefit from waterproofing, and chimneys with Gelco liners are no exception. Winter freezes followed by thaws push water into brick pores and micro-cracks, and repeated cycles cause spalling. We use breathable siloxane-based waterproofing on masonry that protects the structure without trapping moisture. For an assessment of your chimney’s specific condition, call (762) 249-4619 for a free estimate.
