How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with Gelco-style cap interfaces: The foam liner’s top termination can degrade where it meets a standard cap, especially in Chesapeake’s salt-air environment near the Elizabeth River and Great Bridge canals. We see the foam crown wash eroding at the flue exit, which lets water migrate behind the cap and rust the anchor tabs. Our fix is a custom-fitted Gelco or Famco cap with stainless steel hardware and a proper storm collar, never a generic clamp-on that pinches the foam.
• HeatShield UL-Listed stainless steel liner tops with factory spark arrestors: The factory mesh on early 2000s installations was 19-gauge in some runs, thinner than current 22-gauge spec. In Chesapeake, where pine needles from loblolly stands clog arrestors every fall, that lighter mesh fatigues at the weld and tears free. We replace with a heavier aftermarket arrestor or a full Gelco cap with built-in screen, matched to the liner diameter so draft isn’t restricted.
• HeatShield poured crown coatings over original concrete crowns: The cerfractory slurry is excellent for vertical flue walls but was sometimes extended onto the horizontal crown as a “seal.” It doesn’t flex like concrete, so after five to ten Chesapeake freeze-thaw cycles, it spider-cracks and traps moisture against the brick below. We grind off the failed coating, assess the concrete substrate, and either repour with proper crown mix or apply a flexible crown sealant from Copperfield that moves with the masonry.
• Multi-flue HeatShield installations with shared caps: When two flues are lined and capped under one broad lid, differential expansion between the liners can torque the cap frame. We’ve tracked this in Chesapeake’s older Greenbrier and Western Branch homes where the original chimney was built with offset flues. The fix is individual flue caps or a reinforced custom frame from Olympia Chimney that allows independent movement.
• HeatShield tee-top connections with deteriorated crown wash: The tee support needs a level, solid crown to bear against. If the crown wash has washed out, the tee settles, the cap tilts, and water runs directly into the flue. We rebuild the crown wash with proper slope and overhang, then reset the tee and cap to factory spec. No shortcuts with shims or caulk.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your HeatShield system if you know it, and books a Level-2 camera inspection. We don’t guess from a phone description.
2. 2
   Inspection and documentation. Our tech runs a camera up the flue, photographs the cap, crown, and liner top from inside and out, and records the HeatShield series markings if visible. You get the photos and a plain-English verdict before any work is proposed.
3. 3
   Parts decision. If the cap is salvageable, we say so. If not, we source OEM-compatible caps from Gelco, Famco, or Olympia Chimney, or a DuraFlex termination if your HeatShield liner is part of a hybrid system. We explain the trade-off and let you decide.
4. 4
   Repair execution. Crown work includes grinding, bonding agent application, and either repour or coating per the inspection findings. Cap installs get new hardware, proper storm collar, and sealant rated for 1,200 degrees.
5. 5
   Post-repair verification. We run the camera again to confirm clear passage, check draft with a manometer, and verify cap clearance and screen integrity. Photos go in your file.
6. 6
   Cleanup, paperwork, and guarantee. The 90-Day Done Right Promise goes in writing before we leave. The number on the estimate is the number on the invoice.

Why Chesapeake Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We’ve been working throughout Chesapeake for years, including plenty of jobs in the older homes over near the Great Bridge neighborhood where those brick fireplaces get a real workout every winter. Russell Haines and our crew know the difference between a HeatShield foam liner top and a stainless tee termination, and we stock the parts to fix either without a two-week order delay. Our Level-2 camera inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. The 90-Day Done Right Promise is in writing, no arguing. If the chimney’s right, you won’t hear from me until next season. That’s the point.

We also service DuraFlex and Gelco systems, so if your HeatShield installation was part of a multi-brand job from years back, we won’t force a single-source mismatch. Done right - and we stand behind it.
