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.

Why Trust Level Two Chimney Kennesaw for Your HeatShield Chimney Cleaning?
HeatShield isn’t a generic refractory mortar you can trowel on and hope for the best. It’s a ceramic-fiber-reinforced system with specific surface-prep requirements, mix ratios, and controlled curing windows that our technicians have spent years getting right. Corrine Halstead, who leads our operation, completed her chimney and heating systems training at Apex Technical School in Manhattan before running rooftops and fireboxes full-time. She’s been in Kennesaw long enough to know that the red-clay soil and brutal summer humidity here create a failure pattern most HeatShield in Marietta pages never mention - moisture wicks through chimney crowns and chase covers, gets behind improperly sealed liners, and causes delamination that looks like a liner problem but starts with water.
We write it down before we ask you to decide anything. That means camera stills of your flue condition, a written scope of work, and a written price - all delivered before we schedule. Our crews are background-checked and uniformed, with license information displayed on every page. Materials come through Haven’s buying network, procured from HeatShield, DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield specifically to keep customer prices honest. And our 365-Day Done Right Promise means if the HeatShield application or repair isn’t right, we make it right.
Common HeatShield Chimney Cleaning Problems We Fix in Kennesaw

- Cerfractos liner delamination from flue tile. This is the failure we see most in Kennesaw, and it usually traces back to one of two causes: improper surface prep before the original application, or moisture intrusion that got in before the liner fully cured. Kennesaw’s humid subtropical climate doesn’t help - summer humidity slows curing and fall cold snaps can trap condensation. When we find a detached liner, we strip the failed section back to sound substrate, re-prep with abrasive cleaning and controlled drying, then reapply HeatShield Cerfractos to factory spec.
- Cracking and spalling over soot-contaminated flue surfaces. HeatShield requires a clean, sound bonding surface. If a previous installer skipped the pre-clean or applied over Class III glazed creosote, the surface underneath continues to off-gas and degrade. The HeatShield layer cracks, flakes, and eventually pulls away. We remove all compromised material and start with a proper sweep and deglazing before any new application.
- Excessive shrinkage and pull-away at flue tile joints. HeatShield joint repair compound needs to be packed firmly into mortar joints and allowed to cure slowly. Rushed jobs in Kennesaw’s temperature swings - hot attic chases in August, cold flues in January - often shrink and leave gaps. We control the cure environment and verify joint fill with camera inspection before signing off.
- Crown and flashing seal degradation from UV and thermal cycling. Kennesaw’s sun is relentless on south-facing chimney crowns, and the freeze-thaw of winter cold snaps opens hairline cracks that HeatShield crown coat was meant to seal. Once water gets behind the liner, it undermines everything. We repair or replace the crown first, then seal with HeatShield flashing sealant kit - never the reverse.
- Smoke chamber parging failure in prefab conversions. Kennesaw’s 1980s-90s subdivision homes with factory-built fireplaces sometimes get retrofitted with HeatShield smoke chamber repair mortar when the original metal smoke chamber corrodes. If the metal surface wasn’t properly primed or the parging is too thin, it spalls into the firebox. We assess whether the chamber is salvageable or if the prefab unit has reached end-of-life - we won’t resurface metal that’s too far gone.

AfterHeatShield Parts & Our Repair-vs-Replace Approach
We use genuine HeatShield Cerfractos and joint repair compounds, never generic refractory mortars that crack or fail code. Our stock comes through Haven’s buying network, and we keep common HeatShield materials on hand for Kennesaw jobs to avoid delay.
Here’s where we’re direct: sometimes a flue is too far gone for HeatShield resurfacing. Severe tile collapse, multiple cracked courses, or a liner that’s detached over more than 60% of the run - these need stainless steel, not ceramic coating. We carry DuraFlex and Olympia Chimney liner materials for those cases. We’ll show you the camera footage, explain why HeatShield won’t last, and quote the stainless option in writing. No pressure to salvage what shouldn’t be salvaged. Call (678) 535-2204 and we’ll walk you through what we found.
Our HeatShield Service Process - Step by Step

- 1
Diagnosis with NFPA 211 Level 2 Inspection. We run a camera down the full flue length, document liner condition, creosote class, and any delamination, cracking, or joint gaps. You get the photos before we talk price.
- 2
Written scope and price - before scheduling. Clause 1 of the Haven Standard: have it in writing. We specify HeatShield product line, surface prep requirements, and any crown or flashing work needed. No verbal estimates.
- 3
Surface prep and application. For Cerfractos jobs, we abrasive-clean the flue tile, control moisture content, mix to spec, and apply in lifts with proper cure time between. For joint repairs, we pack compound into cleaned joints and verify fill with camera.
- 4
Post-application testing and documentation. We camera-scan the completed work, verify no voids or shrinkage cracks, and document the final condition. Clause 4 of the Haven Standard requires this photo record - it’s standard, not optional.
- 5
Warranty and record archive. Written warranty is delivered with the final invoice. Your documented record stays on file for future reference, next sale, or insurance claim.
HeatShield Products We Service & Install in Kennesaw
We work with the full HeatShield residential line: Cerfractos ceramic-fiber-reinforced mortar for flue resurfacing; joint repair compound for mortar joint restoration; smoke chamber repair mortar for parging corbelled smoke chambers; and crown coat with flashing sealant kit for water intrusion prevention. We stock Cerfractos and joint repair materials locally for Kennesaw response. For homes where HeatShield isn’t the right solution, we also install DuraFlex and Gelco stainless steel liners and components.
We Also Service These Brands

Level Two Chimney Kennesaw is not a single-brand shop. We service and install DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield products - sourced through Haven’s buying network to keep pricing honest. Our technicians carry cross-brand expertise because Kennesaw’s aging prefab housing stock often needs hybrid solutions no one manufacturer covers.
FAQs - HeatShield Chimney Cleaning Service in Kennesaw
No. We are an independent HeatShield service provider with no manufacturer affiliation or authorization. We have applied, repaired, and maintained HeatShield systems in hundreds of Kennesaw homes through direct product training and field experience, but we do not represent HeatShield Corporation. Our independence means we can recommend non-HeatShield solutions when they’re the better fit for your flue condition.
No - HeatShield requires a clean, sound bonding surface. Class III glazed creosote must be removed mechanically or with appropriate chemical treatment through our Chimney Cleaning & Sweep services before any Cerfractos application. Applying over glaze guarantees adhesion failure and delamination within one to two burning seasons. Our Level 2 inspection determines creosote class and prep scope before we quote. Call (678) 535-2204 for a camera inspection.
Look for white or gray powdery residue in the firebox (spalled liner material), pieces of ceramic coating in the cleanout, or a sudden increase in smoke spillage into the room. The only definitive check is a camera inspection - detached sections, through-cracking, and joint gaps are visible on screen. We include this scan in every Level 2 inspection we perform in Kennesaw.
HeatShield Cerfractos is designed to resurface existing clay flue tile - not to serve as a standalone liner in an unlined chimney. If your Kennesaw home has no flue tile (common in some pre-1970s masonry near downtown), we recommend a stainless steel liner instead. We will not apply HeatShield over bare brick or deteriorated parging and call it a liner.
HeatShield Cerfractos requires controlled curing - typically 24-48 hours at temperatures above 50°F with no moisture intrusion. Kennesaw’s fall weather can complicate this; we schedule applications during stable dry windows and may recommend temporary heat in the flue chase. We’ll give you a specific light-off date in writing before we leave. Using the fireplace too early causes shrinkage cracks and voids the repair.
Yes, if the damage is localized and the surrounding liner is sound and well-bonded. We cut back to sound material, feather the edge, and reapply with proper overlap. But if delamination is extensive or the original prep was inadequate throughout, spot repairs become a patchwork that fails sequentially. The camera inspection tells us which scenario we’re in, and we’ll say so plainly.
HeatShield service in Acworth and Kennesaw typically runs $1,800-$3,400 for full Cerfractos flue resurfacing, $450-$850 for localized joint repair with crown sealing, and $280-$420 for Level 2 inspection with creosote removal if no lining work is needed. Final price depends on flue length, access, crown condition, and whether the existing liner must be removed. We deliver a written price before any work is scheduled - call (678) 535-2204 for a free estimate with camera inspection.
