Gelco Chimney Cleaning in Kennesaw, GA | Ashby Chimney Marietta
We provide independent Gelco chimney cap and liner service across Kennesaw, from the historic brick chimneys downtown to the factory-built fireplaces in the subdivisions off Jiles Road and Barrett Parkway. What makes our Gelco work different here is simple: we know which Gelco cap series hold up in Kennesaw’s humid, rainy climate and which ones rust out in five years. Call (478) 796-8742 for a free estimate on Gelco cap installation, replacement, or our Chimney Sweep in Kennesaw.
Ashby Chimney Marietta has worked on Gelco equipment in Kennesaw homes since before most of the 2000s-era subdivisions were even built out. Nathan Corliss, our owner, started in the trade at Los Angeles Trade-Technical College and has spent twenty-two years on roofs and ladders across metro Atlanta, including plenty of chimneys in the shadow of Kennesaw Mountain. We’re an independent Gelco service provider, which means we’re not beholden to a factory line. We tell you when a genuine Gelco part is the right call and when a quality aftermarket stainless cap will do the same job for less money. That’s the honest way to work.
Why Kennesaw Residents Choose Us for Gelco Service
Most homeowners in Kennesaw don’t think about their chimney cap until something goes wrong: a squirrel in the firebox, water stains on the ceiling, or a cap that bangs in the wind all night. By then, the damage is usually bigger than it needed to be. We’ve been inside enough Gelco caps in this city to know exactly what fails and why. The galvanized Gelco caps that went up on hundreds of Kennesaw homes in the 1990s are now hitting their second or third rust cycle. The stainless multi-flue caps on older masonry chimneys near downtown are showing pinhole corrosion from years of creosote acids. None of this surprises us anymore.
We run background-checked, uniformed technicians on every visit, and every job gets a written price before we touch a brush or a wrench. That’s the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails. Our Gelco sales & service work carries the same written guarantee as every repair we do. If a covered repair fails, we return at no charge. No fine print, no phone tag.

Common Gelco Chimney Cleaning Problems We Solve in Kennesaw
Here’s what we actually find when we get on a Kennesaw roof and pull a Gelco cap for cleaning or replacement:
- Premature rust on Gelco galvanized caps. Kennesaw’s humid subtropical climate means frequent rain and high humidity for months at a stretch. Gelco’s heavy-duty galvanized caps, common on 1990s subdivision homes, often show rust within five to seven years. The rust weakens the mounting collar, and then the cap starts banging in the wind or letting rain into the flue.
- Pinhole corrosion in stainless mesh screens. We see this on Gelco multi-flue caps on older Kennesaw masonry chimneys. When homeowners use their fireplaces only occasionally during the mild Georgia winter, creosote sits and its acids eat tiny holes through the stainless mesh. Once the mesh has holes, embers and animals can get through.
- Gelco top-mount damper caps seized open or closed. On older brick fireplaces near downtown Kennesaw, soot and moisture work together to freeze the damper assembly. A damper stuck open means warm air escaping all winter and cold drafts in the living room. Stuck closed means smoke backing into the house the first time you light a fire.
- Debris intrusion through corroded caps. Once a Gelco cap’s mesh screen is compromised, leaves, pine needles, and the occasional acorn get into the flue. In Kennesaw neighborhoods with heavy tree cover, a clogged flue can turn into a chimney fire risk faster than most people realize.
- Water damage around the mounting collar. On factory-built chimneys in Kennesaw’s 2000s-era subdivisions, a loose or corroded Gelco cap collar lets rain run down the outside of the flue pipe. That water ends up on the firebox floor or stains the chase cover. We repair and reseal where the cap is sound and replace when it isn’t.
Gelco Service in Kennesaw: What Local Conditions Mean for Your Equipment
Kennesaw’s build-out pattern tells you a lot about which Gelco caps will fail first. The city grew fast after 1990, and a huge share of the homes in neighborhoods off Jiles Road, Stilesboro Road, and Cobb Parkway went up with factory-built chimneys and Gelco caps installed at construction. Most of those caps were never registered for any kind of maintenance, and most homeowners have never been on that part of the roof. What we’ve learned from hundreds of these calls is that Kennesaw’s specific combination of high humidity and acidic rainfall from Atlanta metro air pollution accelerates rust on galvanized Gelco caps. We regularly pull caps that are five years old and already showing serious rust. A cap that would last twelve years in a drier climate fails in half that time here. That’s not a knock on Gelco; it’s a simple fact about what this air and this weather do to galvanized steel. If you have a Gelco cap on a Kennesaw chimney built after 1995 and you’ve never had it inspected, the odds are decent that it’s already rusting where you can’t see it.
On a street off Jiles Road, our tech pulled a Gelco Premium 304 stainless multi-flue cap from a 2002 brick-and-vinyl colonial that had been letting rain into the flue. The screen was matted with creosote and showing pinholes, and the cap’s mounting collar had corroded enough that the wind was banging it at night. We replaced it with a new genuine Gelco multi-flue cap and sealed the crown, then confirmed with a smoke test that the draft was back to spec. That’s a pretty standard Tuesday in Kennesaw.
Gelco Models & Products We Service in Kennesaw
We service the full range of Gelco chimney caps and dampers homeowners actually have on Kennesaw roofs.

AfterGelco Service Pricing in Kennesaw
Most Gelco cap replacements in Kennesaw run between $325 and $650, depending on the cap model, flue size, and the condition of the mounting surface. A simple cap swap on a single-flue factory-built chimney sits at the lower end. A Gelco multi-flue cap on an older masonry chimney with a chewed-up crown runs higher because the crown needs to be sealed before the new cap goes on. Our Chimney Inspection in Kennesaw, which includes a full chimney cleaning with cap inspection, typically runs $199 to $349. Every estimate is a written price before any work starts, so the number we quote is the number on the invoice. Call (478) 796-8742 for an exact quote. Estimates are free, and we’ll tell you over the phone whether we think you need a repair or just a cleaning.

FAQs – Gelco Chimney Cleaning in Kennesaw
The big-box Gelco caps are usually the galvanized models, and galvanized steel does not hold up well against Kennesaw’s combination of high humidity and acidic rainfall from metro Atlanta air pollution. We see rust within five years on many of these caps. A stainless Gelco cap costs more up front but typically outlasts galvanized by two to three times in this climate. Call (478) 796-8742 and we’ll help you figure out which cap makes sense for your chimney.
It depends on what’s seized. If the issue is soot buildup and light corrosion on the pivot mechanism, we can often clean and lubricate it and get it working again. If the damper plate is warped from heat or the mounting frame is rusted through, replacing the whole Gelco damper cap is the honest fix. We’ll show you what we’re seeing before we recommend anything.
Once a year is the safe answer for most Kennesaw homes, even if you only burn a few fires each winter. Zero-clearance fireplaces tend to produce finer creosote that packs into the mesh screen, and Kennesaw’s mild winters mean fireplaces get used lightly and then sit, letting creosote acids work on the cap. An annual sweep plus cap inspection catches pinhole corrosion before it becomes a water leak. Call (478) 796-8742 to schedule.
A heavily creosoted cap can sometimes be cleaned if the steel underneath is still solid. We brush and scrape the mesh, inspect for pinholes and rust, and make a call from there. But if the creosote has already eaten through the stainless mesh or the mounting collar is rusted, cleaning won’t buy you much time. We’ll tell you straight which situation you’re in.
Pre-1900 chimneys in downtown Kennesaw often have non-standard flue tile sizes, and off-the-shelf Gelco caps don’t always fit. In those cases we measure the flue precisely and either source a larger Gelco cap with a custom mounting band or recommend a quality aftermarket stainless cap sized to the opening. We have not found a flue size we couldn’t fit yet. Call (478) 796-8742 for a free measurement.
