How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with corroded chase covers. In Seaford, we see this often on 1980s and 1990s ranches near Seaford Harbor where salt air accelerates galvanized steel corrosion. The chase cover sits above a Cerfractory relined flue, and when it rusts through, water dumps directly onto the foam liner’s top plate. We replace with a stainless chase cover or proper cap assembly, then inspect the foam crown seal for salt-induced degradation.
• HeatShield UL listed relining with failed factory-installed caps. The original cap on these systems uses a lighter-gauge mesh than aftermarket equivalents. After 10-15 Seaford winters, the mesh fatigues at the weld points and blows off in nor’easters. We source heavier-gauge replacement caps with reinforced seams, or step up to a Gelco or Copperfield cap if the flue configuration allows, always documenting the change for any future warranty claim.
• Cerfractory Foam crowns with hairline cracking from thermal cycling. HeatShield’s foam crown application is excellent when new, but Seaford’s freeze-thaw cycles - particularly on south-facing exposures - open micro-fissures that wick water. We do not simply caulk over these. We grind back to sound material, apply HeatShield-compatible crown coat where the substrate permits, or recommend full crown rebuild when the crack network exceeds roughly 30% of surface area.
• Multi-flue HeatShield installations with inadequate cap sizing. Some original installers used single-flue caps on multi-flue HeatShield runs to save cost. Rain and debris enter the unprotected flue, staining the exterior and degrading the liner top. We measure each flue center-to-center, then fabricate or order a proper multi-flue cap with correct overhang - usually 3-5 inches beyond the chimney edge on Seaford’s windward exposures.
• HeatShield top-sealing dampers integrated with damaged crowns. The damper frame is only as good as the crown it mounts to. When the crown spalls or the throat seal fails, the damper jams open or leaks. We separate the repair decisions: crown first, damper second. Russell Haines has seen too many Seaford homeowners quoted full damper replacements when the real problem was a $400 crown repair underneath.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks about your HeatShield system age and symptoms, and books a Level-2 camera inspection. No deposit required.
2. 2
   Inspection with documentation. Our technician runs a camera down the flue, photographs the cap, crown, and top plate from the roof, and delivers a plain-English verdict with photos you can see on the spot.
3. 3
   Parts decision. We check HeatShield OEM availability against quality aftermarket options from Gelco, Copperfield, or Famco. We explain the trade-off - warranty preservation versus durability upgrade - and let you decide. No pressure.
4. 4
   Upfront pricing and signature. The estimate number is the invoice number. We agree on scope, price, and timeline before any work begins.
5. 5
   Repair and testing. Cap or crown work is completed, joints are checked, and we verify proper draft and clearance with a smoke test or digital gauge.
6. 6
   Cleanup, photos, and guarantee. We leave the work area clean, provide after-photos, and activate your 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.
