How HeatShield Products Fail - and How We Fix Them

• HeatShield ProLiner top collars and termination caps: The ProLiner’s stainless collar where it meets the masonry crown takes a beating in Bethlehem’s freeze-thaw cycles. Water gets behind the collar, freezes, and pushes the seal loose. We see this most on homes north of Center Street where the older brickwork has more absorption. We remove the collar, reseat with high-temp silicone, and install a proper Gelco or Famco cap with correct overhang - not the undersized builder caps we often find in place.
• HeatShield Cerfractory Foam crown coatings: The foam system bonds well when applied correctly, but we’ve found premature cracking on crowns that were coated over active water saturation. Bethlehem’s spring rains followed by summer humidity can trap moisture if the crown wasn’t properly dried first. We moisture-test the crown with a meter before any Cerfractory application, and we won’t coat a crown that reads above 15 percent - it’s a waste of your money and our reputation.
• HeatShield Multi-Flue cap fitment on historic Bethlehem chimneys: The standard Multi-Flue cap works fine on modern construction, but in the Hill-to-Hill district and around the historic Moravian buildings, flue spacing is irregular. We’ve fabricated custom mounting brackets using Copperfield hardware to get proper coverage without drilling into historic brick - a detail that matters when you’re working on a home built before 1900.
• HeatShield UL Listed termination caps with internal wind baffles: The baffle design reduces downdraft, but the internal mesh can clog with creosote if the homeowner burns unseasoned hardwood - common around here with all the oak and maple available from local tree services. We clean the baffle assembly as part of every cap service, and we’ll tell you straight if your wood moisture content is the real problem.
• HeatShield relining projects where the new liner terminates below the crown: This is a specification issue we catch during Level-2 inspections. The liner must extend to the proper height above the crown for the cap to function. We’ve seen installations where the liner was cut short to save material, leaving a gap that funnels water straight into the flue. We extend the liner with DuraFlex connector pipe and install a proper Gelco cap - done right, and we stand behind it.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule: A live person answers, day or night. We ask what HeatShield product you have, if you know it, and what you’re seeing - water in the firebox, rust stains on the brick, a cap that’s come loose.
2. 2
   Level-2 camera inspection: Our technician arrives in uniform, background-checked, with a camera rig. We photograph the crown, the cap, the flue termination, and the interior condition. You see the photos. We give you a plain-English verdict.
3. 3
   Parts decision: If your HeatShield cap is under warranty and the failure is a manufacturing defect, we document it for your claim. If it’s out of warranty or the issue is installation-related, we quote OEM or quality aftermarket - Gelco for standard caps, Famco for specialty sizes, Copperfield for custom work. You choose. No surprises on the bill.
4. 4
   The repair: For crown work, we grind out loose material, moisture-test, apply HeatShield Cerfractory Foam in lifts if appropriate, or pour a new concrete crown if the damage is too deep. For caps, we install with proper fasteners and sealant rated to 600°F.
5. 5
   Post-repair verification: We run the camera again. We check draft with a manometer. We photograph the finished work.
6. 6
   Documentation and guarantee: You get photos, a written report, and our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.

And because we also work with DuraFlex, Gelco, and other professional-grade brands, we’re not locked into one manufacturer’s parts bin.
