How HeatShield Products Fail - and How We Fix Them

After 42 years in this trade, we have seen HeatShield products perform well and we have seen them fail. The difference is almost always installation conditions, not the material itself. Here is what we encounter in Hicksville homes:

• Cerfractory Foam liner degradation in pre-1980s chimneys. The Foam series bonds to clay flue tile, but in Hicksville’s older Cape Cods off Jerusalem Avenue, we regularly find original tile that was never properly cleaned before application. Moisture from our freeze-thaw winters gets behind the foam, causing delamination. We remove the failed section, recondition the substrate with HeatShield’s own resurfacing mix or a compatible professional-grade alternative, and reapply to manufacturer thickness.
• HeatShield CrownCoat cracking at the drip edge. CrownCoat is a flexible acrylic, yet it still needs proper prep and enough mil thickness. We see this most on chimneys where a previous contractor thinned the product to stretch it or applied it over active moss. The fix is mechanical removal down to sound concrete, treatment with a compatible bonding agent, and reapplication at spec thickness - not another thin skim.
• Joint Repair system failure in offset flues. The Joint Repair slurry is excellent for straight runs, but in Hicksville’s post-war ranches with 45-degree offsets to avoid floor joists, the material can pool thin on the upper shoulder of the offset. We diagnose this with a camera looking upward, not just down. When we find it, we switch to a troweled build-up method or recommend a DuraFlex liner if the geometry is too severe.
• Spalling brick behind a HeatShield liner. This is the one the last guy missed - the liner is intact, but freeze-thaw damage to the exterior brick has opened gaps that let water run behind the flue. In Hicksville, our nor’easter-driven rain hits the northeast exposures hardest. We repair the masonry first, then verify liner integrity before closing up. The chimney doesn’t care what you hoped it was - it shows you what it is.
• Flue gasses condensing in oversized flues with HeatShield narrowing. Some 1950s Hicksville chimneys were built for coal or oil and are massively oversized for modern gas inserts. HeatShield’s Foam can reduce the flue diameter, but if the reduction is miscalculated, condensation accelerates corrosion. We measure actual BTU output against flue volume, verify draft with a digital manometer, and adjust the liner profile or recommend a properly sized Gelco insert system.

Our HeatShield Chimney Repair Process

1. 1
   Call and schedule. A live person answers, day or night. We ask what you are seeing - water, odor, draft problem, debris - and book a Level-2 inspection with camera.
2. 2
   Camera inspection and documentation. Our technician runs a high-resolution camera the full flue length, photographs every joint, offset, and anomaly, and records the findings. You get the photos and a plain-English verdict before any repair is discussed.
3. 3
   Parts decision: OEM HeatShield or compatible professional-grade. For warranty-active installations, we use HeatShield OEM materials. For older systems out of warranty, we may recommend compatible professional-grade materials from our inventory - always disclosed, never substituted without your written approval.
4. 4
   Repair execution. Background-checked, uniformed technicians complete the work. Mortar repointing, spalling brick repair, crown rebuild, or liner restoration - most jobs finish in one visit. We protect your floors and clean behind ourselves.
5. 5
   Post-repair verification. We camera the repair, test draft and flow, and show you the after photos. No hand-waving, no “trust me.”
6. 6
   Written guarantee and invoice. The 90-Day Done Right Promise, in writing, no arguing. The number on the estimate is the number on the invoice.

Why Hicksville Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We are not a franchise. We are not a one-truck operator who may answer the phone next year and may not. Hearthstone Chimney Co. has served Hicksville and surrounding communities since 1984 - 42 years - and we plan to be here in thirty more. That changes how we treat every job.

Our technicians know HeatShield products specifically, not just chimneys generally. They also work with DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield systems, which means when a HeatShield repair is not the right solution, we can recommend and install the alternative that is - without calling in another contractor.

The 90-Day Done Right Promise is in writing, not a handshake. If it is not right, we come back. No paperwork to find, no arguing about whose fault it was. We are also the company that answers the phone with a live person at 2 AM on a Sunday, because chimneys do not fail on a schedule.
