How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing lifts or delaminates in HeatShield’s UL-Listed system. In New City, we see this most often in homes built during the 1960s and 1970s near the Tappan Zee corridor where original clay flue tiles were resurfaced rather than replaced. The foam cures hard, but freeze-thaw cycling through Rockland County winters can stress the bond, especially where the flue meets a cooler exterior wall. We grind back to sound substrate and reapply to HeatShield’s specified thickness, or recommend a DuraFlex stainless liner if the underlying tile is too far gone.
• Joint Repair system gaps reopen between original flue tile sections. HeatShield’s Joint Repair is meant to seal mortar joints from the inside, but in chimneys with chronic water intrusion - common in New City’s older split-levels near Veterans Memorial Park where flashing was never properly integrated - the repair can’t hold if the moisture source isn’t stopped. We camera-inspect first, fix the flashing or crown, then re-run the Joint Repair so it has a dry environment to cure.
• ProForm liner installations show cracking at the smoke chamber transition. The ProForm poured refractory system is excellent for reshaping a damaged smoke chamber, but it demands precise formwork and controlled curing. We’ve found botched ProForm jobs in New City where the previous installer rushed the pour or used non-HeatShield release agents, leaving a rough surface that catches creosote and cracks under thermal shock. We strip and re-pour to spec, or switch to a Gelco parged smoke chamber if the geometry won’t hold a form.
• HeatShield CrownSeal shrinks and alligators on flat crowns with poor slope. CrownSeal is a flexible, breathable coating, but it’s not a structural fix. On chimneys in New City with dead-level or negatively sloped concrete crowns - we see plenty near the older ranch homes off South Little Tor Road - water pools, freezes, and pushes the coating off from below. We rebuild proper crown pitch first, then apply CrownSeal as the protective layer it was designed to be.
• Factory-built metal chimney chase covers rust through at the corners. While not a HeatShield-manufactured component, many HeatShield liner systems in New City were installed in prefab chimneys with original galvanized chase covers that last maybe 15 years in our snow load and salt-air environment. We replace with a proper copper or stainless chase cover from Copperfield, then inspect the HeatShield liner for corrosion staining that signals hidden water damage.

Our HeatShield Chimney Repair Process

1. 1
   Live answer and scheduling. A real person answers your call to (845) 599-0930, any hour. We book a window that works for you, not a four-hour guess.
2. 2
   Level-2 camera inspection with photo documentation. Our technician runs a chimney camera from top to bottom, records the footage, and marks still images of every defect. You see what we see. No surprises.
3. 3
   Plain-English verdict and upfront pricing. Russell Haines or one of our senior techs explains what’s actually wrong, whether your HeatShield product can be repaired warranty-safe or needs replacement, and exactly what the job costs before we start. The number on the estimate is the number on the invoice.
4. 4
   OEM-spec repair or quality alternative. We use HeatShield materials where the repair calls for them, or specify DuraFlex, Gelco, or other professional-grade brands when the situation demands a different approach. We never substitute builder-grade parts.
5. 5
   Post-repair testing and documentation. We run another camera pass, pressure-test where applicable, and leave you with photos, a written report, and our 90-Day Done Right Promise. If it’s not right, we don’t leave until it is.
6. 6
   Cleanup and follow-up. Background-checked, uniformed technicians protect your floors and furniture. We check in after the first firing to confirm everything’s performing as expected.
