How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner resurfacing - the foam application can delaminate in Hicksville’s freeze-thaw cycles when the original underlying clay liner was too fractured to provide a sound substrate. We see this in the ranch-style homes near Jerusalem Avenue where the original 1960s clay was already spider-webbed before the foam went on. Our fix: camera inspection to assess substrate integrity, then either re-apply with proper surface prep or recommend a stainless steel liner if the clay is too far gone. The chimney doesn’t care what you hoped it was - it shows you what it is.
• HeatShield UL Listed stainless steel liners (304 and 316Ti series) - the 304 series can develop pinhole corrosion when used with pellet appliances or in chimneys with marginal draft, which is common in the tighter, well-insulated Cape Cods off Broadway Mall. We replace with 316Ti or upgrade to DuraFlex when the application demands it, and we document the alloy grade in writing.
• HeatShield flexible liners in offset flues - the multi-ply construction can fatigue at sharp offsets, particularly in Hicksville’s older colonials where the chimney was built around a central stack with a dogleg. We find the crease point with a camera, then either splice in a rigid section or replace with a more suitable Gelco or DuraFlex configuration.
• HeatShield connector pipes and appliance adapters - the crimped seam joints loosen over thermal cycles, especially where the pipe meets a cast-iron stove collar. We see this in homes burning seasoned hardwood versus the softer stuff from local tree services. We replace with OEM-spec or equivalent aftermarket, torque to spec, and leak-test with a smoke pencil.
• HeatShield refractory panels in zero-clearance fireplaces - the panels crack from thermal shock when homeowners burn with the glass doors closed or overload the firebox. Russell Haines has pulled more cracked HeatShield panels out of Levittown-adjacent ranches than he can count. We measure, order exact replacements, and install with the proper expansion gap - no guesswork.
