How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with corroded caps: The Cerfractory Foam liner is built to take heat, but the original cap that came with many Shelton installations from the 2008-2016 era was galvanized steel with a thinner gauge than the liner itself. We’ve pulled dozens of these caps off Huntington Center colonials where the salt air from Long Island Sound accelerated rust-through at the mesh base. We replace with a stainless or copper cap matched to the flue diameter, never reusing a compromised cover.
• HeatShield UL-listed relining jobs with crown separation: After a HeatShield liner is poured, the crown must be resealed to the new flue opening. If the original crown was skim-coated rather than properly rebuilt, the thermal expansion differential between the Cerfractory Foam and the old concrete causes a gap within two to three winters. We see this especially on the pre-1980s capes in White Hills where the crown was never more than a thin mortar wash. We cut back to sound concrete, apply a proper crown coat, and seal the penetration with a high-temp silicone rated to the liner spec.
• HeatShield ProLiner multi-flue caps with sagging lids: The ProLiner system often serves two flues under one cap, and the stock cap uses a lighter-gauge lid that can sag when snow load builds on the shallow-pitch Shelton roofs common near the river. The sag traps moisture against the mesh, and the mesh rusts from the top down. We spec a Gelco or Famco multi-flue cap with a steeper lid pitch and heavier gauge, or fabricate a custom solution when the flue spacing is non-standard.
• HeatShield factory-built cap installations with improper overhang: Some HeatShield caps were installed with too little overhang beyond the flue tile edge, letting water run straight down the face of the chimney. In Shelton’s freeze-thaw cycle, that water gets behind the crown and pops the surface within a season. We measure overhang to minimum 2 inches past the flue tile, or replace with a cap that has a proper drip edge built in.
• HeatShield Cerfractory Foam systems with crown wash failure above the smoke chamber: The Cerfractory Foam liner stops at the smoke chamber, but the crown above it is still original masonry. We’ve found crown wash failures on these jobs where the previous contractor assumed the liner warranty covered everything above the roofline. It doesn’t. We treat the crown as its own system, camera-inspecting the interface and re-coating with a compatible crown sealant that won’t outgas and degrade the foam collar.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, day or night. We book a Level-2 camera inspection with photo documentation.
2. 2
   On-site diagnosis. Our tech runs a camera down the flue to verify the HeatShield liner condition, then photographs the cap, crown, and any water intrusion points. You see what we see.
3. 3
   Parts decision. If the HeatShield cap is salvageable, we say so. If not, we source OEM-equivalent or upgraded aftermarket from Famco, Gelco, or Copperfield, never a big-box substitute. For crowns, we match sealant to the Cerfractory Foam temperature rating.
4. 4
   The repair. Cap replacement takes 1-2 hours. Crown coating or repair takes 2-4 hours, with cure time factored in. We protect your roof and landscaping.
5. 5
   Post-repair test and documentation. We run a final camera pass, verify draft and clearances, and give you a written report with photos and the 90-Day Done Right Promise.
6. 6
   Cleanup and walkthrough. You sign off only when you’re satisfied. The price on the estimate is the price on the invoice.
