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 Residents Choose Us for HeatShield Service
Ruben Castellano, owner of Alcott Chimney Marietta, grew up in East Los Angeles and picked up his first trade skills at Los Angeles Trade-Technical College before moving across the country and putting down roots in Georgia. For well over a decade now, he and his crew have focused on one thing: chimneys. Not the box-store sweep-and-leave routine. Real diagnostic work, with camera scans that show you exactly what’s happening inside your flue. That matters in Marietta because older homes around the Square hide surprises, crumbling mortar, unlined flues, squirrel nests under caps, that generic sweeps miss. We use HeatShield sales & service experience earned on hundreds of Cobb County chimneys, and we treat every job as if it’s on our own block. You’ll know the technician’s name and see their photo before we arrive. That’s the Threshold Standard, and it’s not optional.

Common HeatShield Chimney Cleaning Problems We Solve in Marietta
- Cerfractory sealant spalling along flue walls. Marietta’s heavy spring rains push moisture into the brick, then summer heat pulls it back out. The HeatShield coating bubbles and flakes where water has been trapped behind it. We remove the loose material, address the moisture source, and reapply with a controlled cure so it doesn’t fail again in 18 months.
- Hairline cracks in mortar joints widened by freeze-thaw cycles. Even a mild Marietta winter brings a few nights below freezing. Water in the original mortar expands, cracks widen, and creosote seeps behind the HeatShield liner. That hidden corrosion is why we camera-scan every restoration, not just the parts we can see from the roof.
- Delamination at the smoke chamber on historic flues. Many homes near the Marietta Square were built with shallow, unlined smoke shelves that clog easily and were never properly prepped for coating. HeatShield that’s applied over badly cured mortar will peel. We strip the delaminated area, repoint with lime-based mortar that matches the historic brick, and apply the HeatShield Smoke Chamber Repair System correctly.
- Premature wear on caps and crown coatings from acidic creosote. Short cold snaps harden creosote into a glazed layer that’s slow to burn off. That acidic residue attacks stainless steel and crown sealant. We see it constantly in Marietta’s 1960s and 1970s ranch houses whose chimneys haven’t been swept in years.
- Water intrusion through unlined flues. Plenty of Marietta chimneys, especially in the historic district, still have original unlined flues. Rain flows straight down the brick and behind any surface coating. HeatShield sealing is only effective if the underlying moisture path gets closed first.
HeatShield Service in Marietta: What Local Conditions Mean for Your Equipment
Here’s something specific to Marietta that you won’t read on a national HeatShield page: the historic district has more chimneys with unlined, cobblestone-lined flues per block than any neighboring ZIP code in Cobb County, and most have never been fitted with a modern damper. That changes the failure cycle. In a newer roofline, a HeatShield liner fails from the top down, water gets in through a cracked crown or loose cap. In the Square district, it fails from the inside out. Original mortar joints from the 1920s funnel rain directly into the liner cavity, and the HeatShield coating traps that moisture against the brick instead of shedding it. Our camera inspections around Church Street and Kennesaw Avenue regularly document HeatShield failures caused by exactly this. That’s also why flue sealing has to come before any cap or crown work can hold. If the liner is leaking from inside the flue, a new cap just shifts the water somewhere else. Ruben puts it straight: “Tell me what you’re seeing and I’ll tell you exactly what it means, no guesswork, no upsell.” That’s how we work in Marietta.
HeatShield Models & Products We Service in Marietta
We work on every major HeatShield product line: the Chimney Saver System, Cerfractory Flue Sealant, Joint Repair System, and the Smoke Chamber Repair System. We use genuine HeatShield Cerfractory sealant and repair kits on restorations because the material’s expansion rate is matched to the original flue. That prevents re-cracking when Marietta temperatures swing. For caps, crowns, and flashings, we source code-approved aftermarket stainless steel and copper components, clearly labeled as non-HeatShield where applicable. And we’ll tell you plainly when a repair doesn’t make sense. If HeatShield patching would leave less than 60% of the liner intact, full flue replacement is the honest recommendation. We stock the most common repair materials locally, which keeps Marietta turnaround times short.

FAQs – HeatShield Chimney Cleaning in Marietta
The most common cause on Marietta homes is freeze-thaw cycling pulling moisture through original mortar joints that were never waterproofed before the HeatShield coating was applied. Rain enters the brick in spring, summer heat expands it, and any overnight freeze stresses the bond. No coating survives that if the underlying moisture path isn’t closed. The fix is repointing those joints and sealing the flue interior before reapplying HeatShield. We’ve done this on dozens of older chimneys around the Square where repeated patch jobs kept failing for the same reason. Call (229) 350-8952 and we’ll show you what the camera sees.
Yes. We repoint the smoke chamber with lime-based mortar matched to the historic structure, let it cure under controlled humidity, then apply the HeatShield Smoke Chamber Repair System. Removing original brick is almost never necessary, and on a 1920s bungalow you don’t want to. We recently did this on Church Street near the Square, a home built in the 1920s with a bubbling HeatShield liner in the upper flue. The underlying brick got repointed first, then the joint repair system was applied with a full controlled cure. The homeowner kept their original chimney and got a CameraSonics EV2 scan proving the flue was sealed wall-to-wall.
It depends on the cause. If a storm or falling limb damaged the crown or cap and water got in behind the liner, many policies cover part of the repair. If the failure is from normal wear, aging mortar, or lack of maintenance, most carriers won’t. Creosote buildup or animal nesting damage is generally considered preventable maintenance. We’ll give you a written assessment and camera footage you can submit with a claim. The documentation is yours either way. For an exact quote on the repair itself, call (229) 350-8952.
Every year, ideally in late summer or early fall before burning season starts. Marietta’s humidity accelerates efflorescence and spalling in older brick, and a year of freeze-thaw cycles plus spring rains can turn small mortar cracks into active water paths. An annual Chimney Inspection - Marietta catches that while it’s still repairable. If you burn wood more than twice a week, we recommend a sweep and camera scan at the same time. Call (229) 350-8952 and we’ll fit you into the schedule before the first cold snap.
Only after the flue is sealed and water intrusion is stopped. HeatShield Cerfractory sealant on an unlined flue is a temporary patch at best if rain is still pouring down the brick. On older Marietta ranch houses from the 1960s and 1970s, we often find original chimneys with no liner at all. In those cases, we seal the flue first, then apply the HeatShield system, then install a modern cap and crown coating. The order matters. Call (229) 350-8952 and we’ll do a camera inspection to see what’s really inside your chimney.
