How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam crown coatings (HeatShield ProLine series) can develop hairline shrinkage cracks within 18 to 36 months in Marietta’s clay-heavy soil zones, especially where homes sit on the red Georgia Piedmont. The foam layer separates from the underlying concrete crown as seasonal moisture wicks upward through the masonry. We grind back to sound substrate, apply a bonding wash, and re-coat with compatible Cerfractory material or transition to a poured concrete rebuild if the crown substrate has lost structural integrity.
• Stainless multi-flue caps (HeatShield Guardian line) suffer weld-point corrosion at the corners where condensation pools during Marietta’s February-to-April humidity spikes. The 304-grade mesh hoods hold up well, but the 18-gauge base rails oxidize from the inside out. We source direct-fit replacement bases through Haven’s buying network or fabricate matched rails when HeatShield’s OEM lead time stretches past two weeks.
• Single-flue caps with integral dampers (HeatShield SmartCap series) bind in the track when creosote migrates from the flue collar into the hinge mechanism. This is common in Marietta’s older Whitlock Avenue and Church Street homes where fireplace inserts run long burn cycles. We disassemble the damper, ultrasonic-clean the track, re-seal the collar joint with high-temp silicone, and replace the cap only if the damper blade is warped beyond adjustment.
• Crown wash systems (HeatShield CrownSeal) delaminate when applied over active efflorescence, which we see frequently on north-facing chimney breasts in Marietta’s shaded lots near Kennesaw Mountain. The white salt deposits indicate vapor drive; sealing over them traps moisture and accelerates spalling below. We wire-brush to bare concrete, treat with mild efflorescence inhibitor, and reapply CrownSeal only when a moisture meter reads below 15 percent across three test points.
• Custom copper caps (HeatShield Signature series) develop galvanic corrosion at the stainless-steel fastener points, particularly where Marietta’s occasional hail events have dimpled the copper and cracked the protective patina. The green verdigris is cosmetic; the steel bleed-through at fasteners is not. We replace with copper rivets and bronze hardware, or source a Gelco equivalent cap when the Signature line has been discontinued for that flue dimension.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks HeatShield part availability against our Marietta warehouse stock, and books a Level 2 inspection window. You’ll get a text when your tech is en route.
2. 2
   Camera first, quote second. We run the chimney camera to flue top, photograph the crown substrate, cap mounting condition, and flue collar joint. Corrine Halstead’s rule: camera first, quote second, work third - in that order, every time.
3. 3
   Written scope and price. You receive a written price, written scope, and written warranty before anyone touches a tool. This is Haven Standard Clause 1: Have it in writing.
4. 4
   Parts decision. We use HeatShield OEM when lead time permits and warranty coverage requires it. For discontinued lines or urgent jobs, we match spec through DuraFlex, Gelco, or Olympia Chimney via Haven’s buying network, with the substitution documented in your record.
5. 5
   Repair and test. Cap or crown work completes, we run a post-repair camera pass to verify flue clearance and draft, then photograph the finished condition.
6. 6
   Documentation and guarantee. Your photo record uploads to your job file under Clause 4 of the Haven Standard. The 365-Day Done Right Promise begins.
