How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner degradation in the smoke chamber. HeatShield’s Cerfractory Foam system, common in Elmhurst homes built during the 1990s chimney relining boom, can develop shrinkage cracks where the foam meets the damper frame. The foam separates from the masonry, creating a gap that allows flue gases to cool and condense before reaching the top. We remove the failed foam section, inspect the underlying masonry with a camera, and rebuild with a stainless steel smoke chamber liner or reapply HeatShield-compatible refractory - whichever the inspection supports.
• ProForm liner joint separation in two-story flues. HeatShield ProForm, the sprayed-cementitious liner system, sometimes shows hairline cracking at the joints between flue tiles in taller Elmhurst chimneys, especially where freeze-thaw cycling is severe near York Woods and other neighborhoods with mature tree canopy holding moisture. The cracks look minor but open under thermal load. We cut back to sound substrate, install a flexible DuraFlex or rigid Gelco stainless liner through the full flue length, and seal the top with a properly sized top plate.
• Cerfractory Foam spalling from sulfur attack. In Elmhurst homes burning high-sulfur cordwood - common in the western suburbs where oak and hickory dominate - the Cerfractory surface can develop a chalky, spalled texture that reduces flue diameter and traps creosote. We measure the remaining liner thickness with a borescope, and if the spall exceeds 3/16 inch, we recommend full liner replacement rather than spot repair. The camera footage goes in your file, Clause 4 of the Haven Standard.
• ProForm delamination from improper original application. ProForm requires a specific ambient temperature range during curing; jobs rushed in late autumn around Elmhurst sometimes failed to bond to glazed terracotta. The liner sounds solid when tapped but shears off in sheets. We verify delamination with a scratch test during camera inspection, then quote a full stainless liner replacement with a written price before any demolition starts.
• Top plate and collar corrosion on HeatShield-terminated systems. HeatShield’s original galvanized top plates, used through the mid-2000s, rust through at the collar where they meet the flue in Elmhurst’s wet spring seasons. Water stains on the exterior masonry below the crown are the tell. We replace with a 304 or 316 stainless top plate, properly counterflashed, and document the collar fit with photos - not because it looks good, because it prevents the next leak.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Camera inspection and condition report. We run a chimney camera the full flue length, record the footage, and note liner model, failure mode, and masonry condition. You get a copy. Corrine Halstead reviews every inspection before an estimate goes out - she’s usually at her kitchen table annotating photos, which her husband calls a hobby and she calls quality control.
2. 2
   Written price and scope delivered. We specify OEM HeatShield parts versus quality aftermarket alternatives from our Haven buying network, explain the trade-off, and fix the price. Clause 1 of the Haven Standard: have it in writing before anyone starts.
3. 3
   Parts procurement through verified suppliers. We source HeatShield-compatible materials, DuraFlex flexible liners, or Gelco rigid systems through our network - never job-site improvisation. The camera doesn’t editorialize. Neither do I.
4. 4
   Liner removal or rebuild execution. For partial rebuilds, we remove failed sections without disturbing sound masonry. For full rebuilds, we work from the top down, protecting the Elmhurst property with drop cloths and debris containment.
5. 5
   Smoke test and final camera verification. We run a smoke pellet test to verify draft and seal, then camera the completed flue to confirm liner integrity and proper termination.
6. 6
   Documentation and warranty. You receive photos, camera footage, a written completion statement, and the 365-Day Done Right Promise. Every record is archived under Clause 4.
