How HeatShield Products Fail - and How We Fix Them

• Cerfractory Flue Sealant delamination in HeatShield UL 1777 systems. The refractory coating can separate from the host flue when exposed to rapid thermal cycling - common in Marietta, where overnight lows in January drop into the 20s while daytime fireplace use spikes. We find this most often in homes near Kennesaw Mountain where wind-driven downdrafts exaggerate the temperature swing. Our fix: mechanical removal of the failed coating, flue-gauge measurement, and reapplication to factory thickness spec or full stainless replacement if the substrate is too compromised.
• JointShield gap recurrence in factory-built chimney systems. HeatShield’s JointShield product seals metal chimney joint gaps, but the sealant can shrink if the original application missed the 1/8-inch minimum gap requirement or if the chimney was operated before full cure. We see this in 2016-2019 builds around West Cobb. We open each joint, verify the gap is within spec, and reapply with proper cure time - or recommend transitioning to a flexible DuraFlex liner if the joint spacing is chronically out of tolerance.
• Smoke chamber parging failure in HeatShield CeCure applications. The CeCure smoke chamber coating flakes when applied over oil-soaked or previously painted masonry. In Marietta’s older Whitlock Avenue homes, we’ve pulled out layers of CeCure that looked intact from below but were hollow behind. Our fix: rotary stripping to bare brick, moisture-content testing, and re-parging only when readings pass - or rebuilding the smoke chamber with proper corbeling if the geometry is too degraded.
• Thermal shock cracking in HeatShield systems serving wood inserts. When a wood insert is over-fired (common with EPA-certified units pushed past their rated BTU output), the concentrated heat exceeds the CeCure thermal envelope. The cracks run vertically, not randomly, following the flue gas path. We map them with the camera, measure crack width at multiple depths, and repair only if under 1/4 inch - otherwise we specify a listed stainless liner sized to the insert’s outlet.
• Water intrusion at the chase cover in factory-built HeatShield chimneys. The chase cover is not a HeatShield product, but its failure destroys the liner below. In Marietta’s spring storm season, we find rust-stained CeCure and corroded JointShield in homes where the chase cover has been leaking for two or more years. We replace the cover with a Gelco or Famco unit, inspect the full liner length, and document whether the damage is localized or requires full replacement.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Camera inspection and written scope. We run a chimney camera the full flue length, record the footage, and mark every defect with time-stamp and depth measurement. You get a copy before we discuss price.
2. 2
   Parts assessment: OEM HeatShield vs. quality aftermarket. We stock HeatShield Cerfractory and JointShield materials through our Haven buying network, but we’ll specify DuraFlex or Gelco stainless if the flue condition warrants a full liner replacement. We explain the trade-off in writing: warranty coverage, lifespan, and total cost.
3. 3
   Written price, signed before work starts. Clause 1 of the Haven Standard - the price and scope are delivered in writing, and nothing changes without your initials. Camera first, quote second, work third - in that order, every time.
4. 4
   Repair or rebuild execution. For liner jobs: isolation, preparation, and application or insertion per manufacturer spec. For rebuilds: course-by-course documentation with photos. Corrine Halstead reviews every rebuild scope personally before the crew starts.
5. 5
   Post-work camera verification and draft test. We re-run the camera, perform a smoke or pressure test where applicable, and compile the final photo record. Clause 4 of the Haven Standard requires this documentation on every job.
6. 6
   Written warranty and 365-Day Done Right Promise. You leave with a warranty document, the photo archive, and our promise: if it’s not done right, we make it right.
