This page is for Hamden homeowners who already have HeatShield components in their chimney system and need a repair done correctly the first time. Maybe you’re in one of the older colonials near Sleeping Giant State Park where freeze-thaw cycles hit hard, or a mid-century brick-stack off Whitney Avenue where the original mortar is giving out. Wherever you are in Hamden, call (475) 369-1614 and a live person will answer.

How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing separates from the clay flue wall. We see this most on HeatShield’s UL-listed Cerfractory Foam jobs in Hamden homes where the original application didn’t account for the region’s wide temperature swings, spring through fall. The foam lifts at the corners first, creating a gap that collects acidic condensation. We remove the failed section, re-abrade the clay substrate, and reapply to HeatShield’s thickness spec, not a shortcut coat.
• HeatShield Joint Repair mortar crumbles at the shoulder joints between flue tiles. In Hamden’s older two-story colonials, thermal expansion from deep winter burns works these joints loose over fifteen to twenty years. We grind out the degraded material to sound substrate, then repack with HeatShield’s specified refractory mortar or a compatible professional-grade equivalent from our stock.
• CrownSeal waterproofing membrane cracks at the chimney crown edge. HeatShield’s CrownSeal is flexible, but Hamden’s freeze-thaw cycle is aggressive, especially on south-facing crowns that heat all day and freeze hard overnight. We cut back the failed membrane, assess whether the crown substrate itself is sound, then reapply or rebuild as the condition warrants.
• FlashingSeal separates at the roofline interface. The HeatShield FlashingSeal system works well when the counter-flashing is properly embedded, but in Hamden we regularly find it applied over rusted base flashing or rotted step flashing that should have been replaced first. We pull it back, replace what’s underneath if needed, then reseal so the repair lasts.
• Factory-built metal chimney chase covers rust through at the corners. HeatShield chase covers in the 304-grade line show pitting after twenty-plus Hamden winters, especially where oak leaf tannins collect and hold moisture. We measure on-site and source a compatible replacement in heavier-gauge material, or coordinate with our Copperfield and Famco suppliers when a custom fabrication is the better path.
