Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
HeatShield Chimney Cleaning in Marietta, GA | Ashby Chimney Marietta
We’re independent HeatShield service providers in Marietta, not manufacturer-authorized, but trained on HeatShield’s cerfractory foam system and its application protocols. What makes our HeatShield work different here is simple: we understand how Marietta’s older shared-wall chimneys and humid climate affect coating longevity, and we inspect for those failure points before we clean. If you need HeatShield inspection, repair, or resurfacing in Marietta, call (478) 796-8742 for a free estimate.
Why Marietta Residents Choose Us for HeatShield Service
Most Chimney Sweep - Marietta companies can sweep a flue. Fewer know what to do when they find a HeatShield coating that’s peeling away from a clay tile liner. Nathan Corliss, our owner, has spent going on twenty-two years working on metro Atlanta chimneys, including plenty of older homes near Kennesaw Mountain where flue conditions demand a steady hand. We’ve completed hundreds of HeatShield resurfacing and repair jobs across Marietta’s housing stock, from antebellum-era fireplaces near the Square to prefab systems in East Cobb subdivisions. Tell you the price first, show you the work, put it in writing. That’s the whole job. Every quote is free, and every repair carries our written guarantee. We stock genuine HeatShield Cerfractory foam and accessories so most Marietta jobs don’t wait on parts.

Common HeatShield Chimney Cleaning Problems We Solve in Marietta
- Spalling and cracked clay tile liners in 1950s-70s brick ranches. Marietta’s humid summers push moisture into masonry, and when that moisture meets a HeatShield coating that was applied over unresolved damp, the cerfractory foam can fail within a few seasons. We see this constantly in neighborhoods built during the post-war ranch boom. The fix is rarely just recoating; it’s addressing the moisture source first.
- Deteriorated mortar joints between flue tiles. Decades of thermal cycling from sporadic, low, smoky fires (the kind Marietta homeowners light on those few cold snaps each winter) expand and contract the joints. HeatShield joint seals delaminate at these points, and a standard sweep misses them. We inspect joints specifically because we know what Marietta’s usage pattern does to them.
- HeatShield coating breakdown in prefab metal chimneys. East Cobb and West Cobb subdivisions from the 1980s-2000s often have factory-built fireplaces. Unseasoned pine, easy to find in Georgia, burns acidic. That creosote corrodes the original metal and undermines the HeatShield bond. A chimney cleaning in these homes often reveals coating failure the homeowner didn’t know about.
- Micro-fractures from chimney fires in historic square homes. Marietta’s pre-1900 homes near downtown often have unlined or parged flues. When creosote ignites, even briefly, it can micro-fracture a HeatShield cerfractory surface. Homeowners who only get a Level 1 inspection miss this. We recommend Level 2 inspections on these older Marietta chimneys before any resurfacing decision.
- Failed HeatShield from cross-flue contamination in shared-wall chimneys. Marietta’s row-house style homes on Whitlock Avenue and Church Street share flue walls with neighbors. Moisture or debris migrating from an adjacent property undermines coating adhesion. This isn’t a problem you’ll find in Kennesaw or Smyrna, and most companies don’t look for it. We do.
HeatShield Service in Marietta: What Local Conditions Mean for Your Equipment
Marietta’s oldest downtown chimneys on Church Street and Whitlock Avenue often share a party wall with the neighboring house. A row-house condition not found in nearby Kennesaw or Smyrna. This matters for HeatShield work in a way most Marietta homeowners never consider: flue work on one side frequently requires coordination with the adjacent property to prevent cross-flue contamination or to gain access from both roofs. On Church Street, our crew found a 1905 brick chimney with an unlined flue that had been previously coated with HeatShield by another company. The cerfractory surface was peeling in sheets due to moisture wicking from the shared wall. We removed the failed coating, repaired the masonry with a custom HeatShield mortar, and installed a stainless steel cap before reapplying the Cerfractory system. The flue now passes a Chimney Inspection - Marietta Level 2 inspection and the musty odor is gone. If your Marietta chimney shares a wall, that shared wall is part of the inspection, not an afterthought.
HeatShield Models & Products We Service in Marietta
We service the full HeatShield product line: HeatShield sales & service covers the Cerfractory Flue Sealant for standard single-flue applications, the Joint Repair System for clay tile liner joints, the CeCure Sleeve Relining System for severely damaged flues, and the Custom-Formulated Repair Mortar for smoke chamber parging. We use genuine HeatShield products exclusively. Aftermarket substitutes are not safe for flue rehabilitation and void any manufacturer-published performance expectations. For minor surface spalling, we resurface. For structural flue damage, we recommend full HeatShield CeCure relining rather than repeated patch repairs. Marietta’s humidity makes band-aid fixes short-lived, and we’d rather do the job once.

AfterHeatShield Service Pricing in Marietta
Most chimney sweeps in Marietta run between $150 and $350 depending on flue condition, access, and whether it’s a standard cleaning or includes a Level 2 inspection. HeatShield work sits above that: resurfacing typically starts around $2,500 and goes up based on flue height, damage severity, and whether shared-wall coordination is needed. A full CeCure sleeve relining on a severely damaged Marietta flue can range from $4,000 to $9,000. What drives the cost: access (historic Marietta chimneys are often steep and tight), existing coating condition, and whether masonry repair is needed before cerfractory application. Every estimate is written, free, and includes camera inspection so you see exactly what we see. Call (478) 796-8742 for an exact quote. Estimates are free.

FAQs – HeatShield Chimney Cleaning in Marietta
Yes, but shared-wall chimneys require coordination with the adjacent property first. We need to confirm the neighboring flue isn’t introducing moisture or debris into yours, and we may need access from both roofs. This is standard practice for row-house style homes on Church Street and Whitlock Avenue in Marietta.
With proper moisture remediation before application, a HeatShield cerfractory resurfacing in Marietta typically lasts 15-25 years. If the underlying moisture source is ignored, it can fail within three to five. That’s why our Level 2 inspection comes before any recoating recommendation. For an exact assessment of your Marietta flue, call (478) 796-8742.
Often yes. For minor cracking, the HeatShield Joint Repair System seals tile joints effectively. For severe spalling or structural damage, we recommend the CeCure Sleeve Relining System instead of repeated patch work. Marietta’s humid summers mean the underlying moisture issue must be addressed first, or any coating will fail early.
HeatShield can help if the odor comes from creosote-soaked masonry or a deteriorating flue surface. But first we check for the common Marietta culprits: rusted dampers from high humidity, efflorescence on masonry, or moisture wicking from shared walls. The coating is part of the fix, not always the whole fix. Call (478) 796-8742 and we’ll camera-inspect before recommending anything.
Yes. A failed coating must be mechanically removed and the substrate cleaned before new cerfractory foam can bond properly. Recoating over flaking HeatShield is a waste of money and will fail again quickly. We include coating removal in our resurfacing estimate.
