What we are is a crew that works on HeatShield systems weekly across Alpharetta’s newer construction and remodels, so we know the brand’s ceramic and stainless flue liners from installation quirks to tear-out realities.

Why Trust Flint Chimney Co Alpharetta for Your HeatShield Chimney Cleaning?
Hank Delano, our owner, learned the trade at Los Angeles Trade-Technical College and has put in over two decades of hands-on chimney work. He and our crew have served Alpharetta for years, running cleanings and inspections on everything from new builds near Avalon to older homes with clay-tile flues that haven’t seen a brush in a decade. That matters with HeatShield because the brand’s cerfractory systems behave differently than raw clay tile or metal liners. You need a tech who knows what a properly bonded HeatShield surface looks like under a camera, and what a failing one looks like too.
We use genuine HeatShield cerfractory, joint sealant, and CeCure sleeve components because the chemistry is specific to the original application. There is no equivalent aftermarket for this stuff. We also follow warranty-safe practices: no shortcuts, no unapproved coatings over HeatShield surfaces, and no repairs that would void your coverage. When we’re done, you get a written report with photos, a written guarantee valid for one full year, and a phone number answered by a live person any hour of any day.

Common HeatShield Chimney Cleaning Problems We Fix in Alpharetta
HeatShield systems are solid products, but they’re not invincible, especially in Alpharetta’s climate. Here’s what we actually find when we open chimneys in this area:
- Hairline cracks in original clay flue tiles that were resurfaced with HeatShield cerfractory but later spall due to moisture intrusion at the smoke shelf. Alpharetta’s high humidity works its way into the smoke shelf area, and when moisture meets a cerfractory surface that’s already under heat stress, the bond starts to break down. You’ll see flaking or small chunks falling into the firebox.
- Deteriorated mortar joints between flue tiles where HeatShield joint sealant has debonded from thermal cycling. Georgia winters may be mild, but cold snaps followed by warm days create expansion and contraction cycles. Over years, this stresses the joint sealant until it pulls away from the tile, and flue gas finds a path through the gap.
- Misapplied HeatShield coating that leaves pinhole voids at corbel transitions. After a wet Georgia spring, these voids show up as white efflorescence staining on the exterior chimney breast. It means the original application didn’t fully cover the corbel transition, and moisture is moving through the masonry.
- Stainless CeCure sleeve pulled loose at the flue offset. We’ve seen this in larger Alpharetta homes where the chimney chase has a 15-degree bend. If the original HeatShield application didn’t account for that offset, the sleeve can work itself loose over time, which compromises the entire draft path.
- Creosote buildup accelerated by Alpharetta’s mild but humid winters. Many wood-burning fireplaces across Alpharetta’s suburban homes get used heavily during cold snaps, and the region’s humidity makes creosote accumulate faster than it would in drier parts of Georgia. That’s why we recommend annual cleanings for any actively used fireplace, HeatShield-lined or not.
Hank has a saying: “Tell me what’s in the flue, and I’ll tell you what it takes to fix it.” We’ve opened plenty of Alpharetta chimneys in neighborhoods like Windward and Crabapple where original terra cotta flue liners cracked under heat stress. HeatShield resurfacing was often the right fix at the time. The question is always whether that fix has held up, and that’s what our camera inspection tells you before we touch a single tool.
HeatShield Parts & Our Repair-vs-Replace Approach
Genuine HeatShield components are the only parts we use on HeatShield systems. The cerfractory compound, the joint sealant, and the CeCure sleeve components all have specific chemistry matched to the original application. An aftermarket substitute doesn’t exist, and we wouldn’t use one if it did. When a HeatShield repair is needed, the material cost reflects that. In Alpharetta, a targeted HeatShield joint sealing job typically runs $450 to $900 depending on how many joints need work and how much access the flue gives us. A full cerfractory resurfacing of a standard two-story chimney usually falls between $2,800 and $4,200.
Here’s where honesty matters. We recommend replacing rather than recoating when the underlying flue structure is beyond saving or the existing HeatShield surface has failed from a chimney fire. Recoating over a compromised base just means paying twice. Our crew will tell you plainly which category your chimney falls into, with camera evidence you can see for yourself. Call (762) 600-1468 and we’ll get you a written number before any work starts.
Our HeatShield Service Process – Step by Step
- 1
Diagnosis: We run a Level 2 inspection with a camera through the full flue path, checking HeatShield surface condition, joint integrity, and any signs of spalling or debonding. You see the footage with us, not a summary after we’ve left.
- 2
Repair or resurfacing: If the fix involves HeatShield joint sealant or cerfractory, we clean the surface to the manufacturer’s prep standard and apply genuine components. For CeCure sleeve work, we measure the exact flue dimensions and account for any offsets or bends before ordering.
- 3
Testing: We verify the draft with a smoke pencil and confirm zero bypass before we pack up. That’s the standard we hold ourselves to, not just a visual glance.
- 4
Warranty: Every repair carries a written guarantee valid for one full year. If a covered repair fails within that period, we return at no charge. The guarantee is on the paperwork, not just a verbal promise.

We Also Service These Brands
While this page focuses on HeatShield, our Alpharetta crews also provide Chimney Sweep services and work across the chimney trade. We install and service DuraFlex stainless liners and Gelco products regularly, which means we’re not married to one brand when another fits the job better. The right material is a decision based on your chimney’s condition and configuration, not on what we happen to have in the truck.
FAQs – HeatShield Chimney Cleaning Service in Alpharetta
No. We’re an independent HeatShield service provider. We use genuine HeatShield materials and follow manufacturer specifications for all applications, but we’re not a factory branch or an authorized warranty center. That independence means we’ll tell you when a different material or approach would serve you better, without a brand loyalty filter.
Yes, but only if the gaps are minor and the surrounding tile structure is sound. HeatShield cerfractory is designed to seal small gaps and surface cracks. If the tiles have shifted significantly or the flue has structural damage, a CeCure stainless sleeve is usually the better option. We’ll show you the camera footage and tell you which category you’re in. Call (762) 600-1468 for a written assessment.
Most two-story HeatShield cerfractory resurfacing jobs in Alpharetta take one full day, occasionally two if we need to repair flue tiles or remove failed coating first. We give you a written schedule before work begins, and our techs arrive inside the window given. You’ll know the timeline in writing, not as a vague estimate.
Cerfractory resurfacing applies a ceramic-modified coating to the inside of your existing flue, sealing cracks and restoring a smooth draft path. A CeCure sleeve is a structural stainless steel liner installed inside the flue. Think of cerfractory as resurfacing a road and CeCure as replacing the pipe. Cerfractory typically costs less; CeCure is stronger and lasts longer. We’ll recommend based on what the camera shows, not on margin.
In most Alpharetta homes, yes. HeatShield cerfractory adds only a thin layer to the interior flue wall, so the existing cap usually stays in place. CeCure sleeves may require a slight cap adjustment depending on the flue opening. We check the cap condition as part of every service and tell you if it needs work, with a separate written price.
We see this in Alpharetta more than in drier climates, and the cause is usually moisture. High humidity, combined with burning unseasoned wood, creates acidic condensation that attacks the cerfractory bond at the smoke shelf and corbel transitions. Our crew opened a 2008 Alpharetta home’s chimney to find HeatShield cerfractory blistered and cracked just above the throat damper, exactly where the previous homeowner had burned unseasoned pine. After mechanical creosote removal, we knocked out the failed coating, repaired two cracked flue tiles with HeatShield joint sealant, and resurfaced that 8-foot section, then tested the draft with a smoke pencil to confirm zero bypass. That’s the difference between a recoating and a real repair. Call (762) 600-1468 for a camera inspection and a straight answer.
A standard chimney cleaning for a HeatShield-lined fireplace in Alpharetta typically runs $180 to $300. If we find creosote buildup that requires mechanical removal or a partial resurfacing, the price increases accordingly, and you’ll see that number in writing before we proceed. Estimates are free. Call (762) 600-1468 and we’ll give you the ballpark over the phone and the exact price after the camera inspection.
