How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with cracked or spalling crowns. The foam liner shrinks and expands with every burn cycle, and that thermal movement transfers stress to the crown above. We see this most in Silver Spring’s older brick colonials near Woodside Park, where freeze-thaw cycles accelerate the cracking. We grind back to sound concrete, apply a bonded crown coat rated for the expansion, and verify the flue gap is correct so water can’t pool.
• HeatShield UL-listed stainless caps with corroded mesh on multi-flue setups. The 304-grade mesh in earlier HeatShield multi-flue caps can pit when trapped moisture sits against it, especially on north-facing chimneys that don’t dry out quickly. We match the flue spacing exactly - HeatShield’s multi-flue specs are precise - and we source either OEM mesh or 316-grade aftermarket when the homeowner wants longer corrosion resistance.
• HeatShield ProFlex liner terminations with loose or missing storm collars. The ProFlex termination kit uses a compression-fit storm collar that can work loose after years of expansion cycling. Water runs straight down the flue pipe and into the attic. We replace with a correctly sized collar, seal with high-temp silicone rated to 500°F, and check the flashing integration - half the leaks we trace start at the collar, not the cap.
• HeatShield poured crown systems with improper overhang or drip edge. Some original installations skimped on the 2-inch overhang HeatShield specifies, or the drip edge was formed wrong. Water sheets back to the brick and saturates the wythe. We form and pour to HeatShield’s own dimensional spec, or coat with CrownCoat when the structural concrete is sound but the profile is wrong.
• HeatShield relined chimneys with mismatched cap sizing causing drafting problems. A cap too small for the new liner diameter restricts draw; too large and it won’t keep out driving rain. We measure the actual flue opening after the liner is in place, not the original clay tile size, and spec the cap accordingly. In Silver Spring’s dense tree canopy, we also check for leaf and seed debris that compounds the restriction.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing, and books a window. We don’t do callbacks or app queues.
2. 2
   Level-2 camera inspection on arrival. Our tech runs a camera up the flue, photographs the crown, cap, and flue walls, and shows you the images on-site. You see what we see. No surprises.
3. 3
   Parts decision with options. If your HeatShield cap is a standard single-flue, we likely have it on the truck. For discontinued ProFlex terminations or custom multi-flue setups, we explain OEM versus quality aftermarket - 316 stainless, better mesh, same fit - and what each costs before any work starts.
4. 4
   The repair. Crown work gets ground, bonded, and formed to shed water. Cap replacements get torqued to spec, collars sealed, and flashing checked. We verify draw with a smoke test or draft gauge.
5. 5
   Documentation and guarantee. You get photos of the completed work, a plain-English summary, and the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing, no paperwork chase.
6. 6
   Cleanup and final walk. We haul away the old cap or crown debris, check the roofline for stray fasteners, and confirm you’re satisfied before we leave.
