How HeatShield Products Fail - and How We Fix Them

HeatShield makes solid chimney components, but no material survives freeze-thaw cycling, poor original installation, or decades of deferred maintenance. In White Plains, where winter temperatures swing from single digits to rain in a week, we see consistent failure patterns across specific HeatShield lines. Here is what shows up in our field notebooks:

• HeatShield Cerfractory Foam liner resurfacing develops hairline cracking and delamination where the original application was too thin at the smoke chamber shoulder. In White Plains colonials with deep, narrow fireboxes - common in Gedney Farm and the Highlands - this stress point fails first. We grind back to sound substrate and reapply at the specified ¼-inch minimum, then verify thickness with a borescope.
• HeatShield UL-listed stainless steel chimney liners (the 316Ti and 304 alloy series) suffer crevice corrosion at the collar joint when condensate pools in offset sections. White Plains’ wet shoulder seasons keep liners damp for weeks. We replace the collar with OEM-spec 316Ti, seal with HeatShield-approved high-temp silicone, and correct the slope so water drains to the cleanout.
• HeatShield Pro-Form smoke chamber parging sloughs off in sheets when applied over oil-soaked or previously painted masonry. We see this in older White Plains homes where fireplaces burned unseasoned oak for decades. Our fix: mechanical abrasion to bare brick, application of HeatShield’s own bonding agent, then parging to NFPA 211 depth standards.
• HeatShield factory-built chimney chase covers - the galvanized and aluminum models - rust through at the drip edge in 12 to 18 years, faster than the stainless equivalent. White Plains’ road salt aerosol accelerates this. We measure in-place and fabricate a replacement from heavier-gauge material, or upgrade to copper if the homeowner plans to stay put.
• HeatShield crown sealant (the brushable membrane product) cracks at the flue tile interface when the underlying crown was never properly pitched. Water backs up, freezes, and pops the sealant. We remove the failed membrane, re-pitch or rebuild the crown with proper slope, then reapply the sealant so it lasts.

Our HeatShield Chimney Repair Process

1. 1
   Call and schedule. A live person answers 24/7. We book a Level-2 camera inspection, not a sales visit. You get a 2-hour arrival window and a confirmation call the morning of.
2. 2
   Inspection and documentation. Our technician runs a camera from firebox to cap, records video and stills, and marks every defect on a diagram. You see the footage on a tablet before we discuss anything.
3. 3
   Diagnosis and parts decision. We identify your HeatShield series, check warranty status, and source OEM parts when available. For discontinued lines, we use quality aftermarket from DuraFlex or Gelco that meets or exceeds original spec - and we tell you which we’re using and why.
4. 4
   Upfront pricing and approval. You get one written estimate with the final number. No line-item padding, no “while we’re here” surprises. Approve it, and we start. Decline it, and you owe nothing for the inspection.
5. 5
   Repair and testing. We complete most HeatShield repairs in a single visit. Afterward, we run a combustion spillage test and another camera pass to verify the fix. You get photos, the test results, and a written report.
6. 6
   Cleanup, guarantee, and follow-up. We haul away debris, lay down fresh drop cloths in reverse, and leave a copy of our 90-Day Done Right Promise. If something is not right, we come back. No paperwork to file, no arguing.
