Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterWhy Marietta Homeowners Choose HeatShield Chimney Cleaning
Emberly Chimney Cleaners Marietta provides independent HeatShield in Marietta chimney cleaning and repair service across Cobb County. We specialize in HeatShield Cerfractory and Resurfacing Systems, using genuine HeatShield materials for warranty-safe repairs backed by our 365-Day Done Right Promise. Call us at (470) 288-2763 for a written estimate before any work begins.
We are not affiliated with or authorized by HeatShield. We’re an independent Marietta-based chimney service with hundreds of HeatShield relining and resurfacing projects completed on local homes. Our expertise comes from field experience diagnosing HeatShield failures in North Georgia’s humidity and freeze-thaw cycles, not from a manufacturer’s certificate on the wall.
Marietta’s housing stock presents a particular challenge for HeatShield systems. The 1970s through 1990s subdivision boom across East Cobb and West Cobb filled thousands of homes with factory-built fireplaces now at or beyond their rated service life. Because Marietta’s mild winters make these fireplaces recreational rather than essential, homeowners routinely skip cleanings for years. A single inspection often uncovers cracked refractory panels, failed gaskets, and hidden creosote buildup in aging prefab chases simultaneously. Chimney cleaning here is as much a safety audit as a sweep.
That pattern matters for HeatShield. Incomplete low-temperature burns, the kind that happen when Marietta residents light a fire only on the occasional cold January evening, deposit sticky second-stage creosote without ever burning it off. That creosote traps moisture against HeatShield coatings. Combined with roughly 50 inches of annual rainfall and clay-heavy soil that shifts through wet-dry cycles, the conditions here accelerate spalling, delamination, and adhesion failure that might progress more slowly in drier climates.
Why Trust Emberly Chimney Cleaners Marietta for Your HeatShield Chimney Cleaning?
Corrine Halstead, our owner, grew up in Queens and picked up her first brush at a vocational program through Apex Technical School in Manhattan before making her way south. She has spent the better part of two decades cleaning and inspecting chimneys across Marietta, including plenty of afternoons working older homes along Whitlock Avenue where the masonry tells its own story. She is known for running a camera before quoting a price and for writing down every finding in plain language before asking a homeowner to sign anything. Camera first, quote second, work third - in that order, every time.
Our technicians know HeatShield products from hands-on repair work, not from a training slideshow. We’ve opened up Cerfractory-lined flues that were spalling from the inside out, traced the moisture path back to a failed crown coating, and reapplied the Resurfacing System with the cure times adjusted for humid summers that make HeatShield service in Kennesaw and Marietta similarly demanding. We stock genuine HeatShield Cerfractory and Resurfacing products, HeatShield Insulation Mix, and HeatShield Premier Crown Repair materials locally. When a stainless steel liner or cap makes more sense than an OEM part, we source quality aftermarket components through our Haven buying network - DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield - specifically to keep customer prices honest.
Every HeatShield job we quote includes a Level 2 camera-scan inspection per NFPA 211, a written scope of work, a written price, and a documented photo record under Haven Standard Clause 4. That archive practice has run continuously since 2009. We’ve completed more than 38,000 chimney inspections and cleanings, every one with a written price before work started and a documented record when it was done.
Common HeatShield Chimney Cleaning Problems We Fix in Marietta
- Cerfractory coating spalling or delaminating. This is the most common HeatShield failure we see in Marietta. Moisture gets behind the Cerfractory layer, usually through a cracked crown or failed flashing, then freeze-thaw cycling pops the coating off in flakes. The root cause is almost always improper original surface prep or excessive moisture in the flue that was never addressed. We remove loose material back to sound substrate, reapply HeatShield Resurfacing System with proper priming, and fix the water entry point so it doesn’t happen again.
- Cracking and separation at the flue collar. When HeatShield mix is applied too thick or over a dirty substrate, it shrinks and cracks at the collar where the flue meets the smoke chamber. Marietta’s humidity extends cure times, and technicians working too fast sometimes stack coats before the previous layer has set. We grind back to clean tile, apply in proper lifts, and allow full cure between coats - even if it means coming back the next day.
- Premature erosion of HeatShield crown coating. HeatShield Premier Crown Repair is a excellent product, but it needs dry conditions during the initial 24-hour cure. Marietta’s summer humidity and sudden afternoon thunderstorms catch unprepared crews. We schedule crown work with weather in mind, use accelerators when appropriate, and tent the work area if needed. A crown that fails in two years because it rained six hours after application is a preventable failure.
- Adhesion failure between resurfacing layer and original clay tiles. HeatShield Resurfacing System requires the host tile to be properly roughened and primed. On older Marietta homes around the Square, soft lime-mortar joints and glazed tile surfaces from decades of use make this step critical. We mechanically roughen, vacuum, and prime before application. Skipping this step saves an hour and costs the homeowner a reline in five years.
- Hidden creosote buildup behind HeatShield coatings. Because Marietta homeowners burn infrequently, second-stage creosote accumulates in layers that can be concealed by a sound-looking Cerfractory surface. During our Level 2 inspection, we look for telltale bulging, discoloration, and odor. When we find it, we remove the creosote mechanically before any resurfacing work begins. Applying HeatShield over active creosote deposits is a fire hazard and a warranty void.
BeforeAfterHeatShield Parts & Our Repair-vs-Replace Approach
We always use genuine HeatShield Cerfractory and Resurfacing products for repairs to ensure warranty-backed performance. For components outside the HeatShield system - stainless steel liners, caps, dampers - we stock quality aftermarket parts compatible with HeatShield installations. Our Haven buying network sources from DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield to keep prices honest without cutting corners.
We never recommend a full reline when a targeted HeatShield repair can safely restore the flue for years. Our tech was called to a 1990s Marietta home with a HeatShield Cerfractory-lined flue that had started flaking near the top. After a Level 2 inspection, we found the crown coating had failed, allowing water to seep behind the HeatShield layer. We removed the loose material, reapplied HeatShield Resurfacing System with proper curing, and sealed the crown with HeatShield Premier Crown Repair - stopping the spalling and restoring a smooth, code-compliant flue. Total cost was a fraction of full relining. Written price before we started. Photo record after. That’s Haven Standard Clause 1 and Clause 4.
If a competitor has told you that full replacement is the only option, bring us their written estimate. Our Free Second Opinion policy means we’ll inspect, document, and give you our honest assessment with no pressure to hire us.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis - Level 2 camera-scan inspection. We run a camera the full length of your flue, document the HeatShield condition, identify moisture paths, and classify any creosote buildup. You see the footage. We don’t guess from the hearth.
- 2
Written scope and price. Before any work, you get a written price, written scope, and written warranty. No exceptions. Haven Standard Clause 1: Have it in writing.
- 3
Surface preparation and repair. For HeatShield resurfacing, we mechanically roughen tile, remove failed coating, address moisture entry, and prime per manufacturer specifications. Prep takes longer than application. We don’t rush it.
- 4
HeatShield application with climate-adjusted cure. We apply HeatShield Cerfractory or Resurfacing System in proper lifts, monitor temperature and humidity, and extend cure times when Marietta weather demands it. Crown work gets scheduled for dry windows.
- 5
Post-repair testing and documentation. We camera-scan again, perform a smoke or pressure test as appropriate, and deliver your documented photo record under Haven Standard Clause 4. The 365-Day Done Right Promise covers our workmanship.

FAQs - HeatShield Chimney Cleaning Service in Marietta
No. We are an independent HeatShield service provider in Marietta, not affiliated with or authorized by the manufacturer. Our credibility comes from field experience with hundreds of HeatShield repairs in North Georgia’s specific climate conditions, not from brand authorization. We use genuine HeatShield materials for warranty-safe repairs and document our work per NFPA 211 Level 2 standards.
Yes, in most cases. Spalling Cerfractory coating can be removed back to sound substrate, the underlying moisture problem fixed, and HeatShield Resurfacing System reapplied for a code-compliant repair. We only recommend full relining when the clay tile host is structurally compromised or the flue is improperly sized for the appliance. Camera first, quote second - call (470) 288-2763 for an inspection.
Look for flaking or powdering on the crown surface, water staining on the exterior masonry below the crown, or dampness in the firebox after rain. On the interior, spalling near the top of the flue often traces back to crown failure. We confirm with a Level 2 camera inspection and moisture assessment. Early crown repair with HeatShield Premier Crown Repair prevents the liner damage that follows.
Yes. HeatShield Cerfractory Flue Sealant is UL-listed for wood-burning applications when applied to a sound clay flue liner per manufacturer specifications. In Marietta, the critical factor is ensuring the flue is free of active creosote and the crown is watertight before application. We clean and inspect first, every time.
Most HeatShield resurfacing jobs in Marietta take one to two days, depending on flue length and cure time needed for humidity conditions. You cannot use the fireplace until the full cure period has elapsed, typically 24 hours after the final coat. We give you a written go-ahead before you light the first fire.
