How HeatShield Products Fail - and How We Fix Them

• Cerfractory Flue Liner (CFL) shrinkage cracks in Kennesaw’s clay-heavy soils. The CFL system is a hybrid ceramic/refractory coating applied to existing clay flue tiles. In Kennesaw, the seasonal expansion and contraction of the chimney structure against our dense, moisture-retentive Georgia clay causes micro-movement at the liner interface. Over 5-10 years, this produces hairline longitudinal cracks that don’t show on external inspection. We find them with a camera scan, then re-coat with HeatShield-compatible Cerfractory mixture or recommend a partial reline if the bond layer has failed.
• Joint Repair (JR) system separation at mortar gaps. HeatShield’s JR product fills eroded mortar joints between flue tiles. When applied over active moisture intrusion - common in Kennesaw after our heavy spring rains hit chimneys with compromised crowns - the JR coating can delaminate from the substrate. We don’t just re-apply; we stop the water first, repair crown cracks with HeatShield CrownCoat or rebuild the crown, then re-apply JR with proper cure time.
• Smoke Chamber Parge (SCP) coating spalling from creosote acidity. The SCP system smooths and insulates the smoke chamber above the firebox. In Kennesaw homes burning seasoned hardwood, Class II and III creosote accumulation creates acidic conditions that break down the parge surface. We remove the degraded coating, mechanically prep the chamber, and re-apply SCP with attention to the throat damper interface - a detail many crews miss.
• CrownCoat flexible crown sealer UV degradation on south-facing chimneys. CrownCoat is a premixed, elastomeric coating for minor crown cracks. On Kennesaw homes with south or west exposure, Georgia sun breaks down the acrylic binder in 3-4 years, causing surface chalking and renewed cracking. We strip failed CrownCoat, assess whether the crown structure is sound enough for re-coating or needs rebuild, then re-apply with proper mil thickness.
• Factory-built metal chimney refractory panel gaps in HeatShield-compatible systems. Some Kennesaw homes have factory-built fireplaces where previous owners installed HeatShield refractory panels as replacements. These panels can shift as the firebox metal frame flexes through heating cycles, opening gaps at the corners that exceed NFPA 211 clearances. We measure the gaps, source correct HeatShield panel dimensions or fabricate from HeatShield-compatible refractory board, and reset with proper expansion allowance.

Our HeatShield Chimney Repair Process

1. 1
   Camera-scan inspection (NFPA 211 Level 2). We run a chimney camera from firebox to flue top, documenting liner condition, joint gaps, and crown integrity. You get the footage and stills before any recommendation.
2. 2
   Written scope and price. Corrine Halstead’s standing rule: we write it down before we ask you to decide anything. Scope, materials list, labor breakdown, and total - signed by both parties before work begins. Haven Standard Clause 1.
3. 3
   Parts decision: OEM HeatShield or verified equivalent. We stock HeatShield Cerfractory, JR, SCP, and CrownCoat mixtures. For components where HeatShield OEM is back-ordered, we source through our Haven buying network from Olympia Chimney or Famco with equivalent spec sheets - always disclosed, never substituted without written approval.
4. 4
   Repair execution with moisture control. HeatShield products fail again if the water source isn’t addressed. We repair crowns, flashings, or chase covers as part of the scope, not as a separate upsell.
5. 5
   Post-repair camera verification and documentation. Second camera run confirms the repair. Photos, footage, and a written completion record go to you and our archive. Haven Standard Clause 4, continuous since 2009.
6. 6
   365-Day Done Right Promise activation. If the repair fails due to workmanship or materials, we return and make it right. The promise is stamped on every job record.
