How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with factory-installed caps: The original cap is often a lightweight galvanized unit that outlasts the foam application but fails at the mesh. We’ve found the 304 stainless mesh on early 2000s Cerfractory installs in Owings Mills has welded seams that crack at the corners after fifteen to twenty winters of freeze-thaw. We replace with a Gelco or Famco multi-flue cap in heavier gauge, matched to the existing flue count, and we document the crown condition beneath before we mount.
• HeatShield UL-Listed poured liners with integrated crown wash: The poured crown is thin by design, usually three-quarter to one inch at the edge. In the clay-heavy soils around Owings Mills, chimney settlement is common on homes built before 1990, and that thin crown develops hairline cracks that let water reach the pour. We don’t just caulk over it. We grind, apply a bonding agent, and rebuild with a proper sloped crown in Portland-based mix, or use a Copperfield crown coat if the substrate is sound.
• HeatShield relined flues with aftermarket cap retrofits: Homeowners sometimes add a big-box cap after the liner install, and the mounting hardware interferes with the liner top plate seal. We’ve pulled caps off in Reisterstown Road corridor homes where the clamp bolts had pierced the top plate gasket. Our fix: remove the wrong cap, inspect the plate, replace the gasket if needed, then install a cap with proper standoff height and correct diameter for the liner.
• HeatShield ProLiner systems with factory top plates: The ProLiner top plate is aluminum and mates to a specific cap profile. Aftermarket caps often don’t seat correctly, leaving a gap that funnels rain directly onto the plate. We stock the correct collar adapters for ProLiner terminations, or we fabricate a transition when the original part is discontinued. Either way, the water stays outside.
• Multi-flue HeatShield installs with shared crowns: When two or three flues are lined and capped independently, the crown between them takes concentrated runoff. We’ve seen this on the older colonials near McDonogh Road where the original brick crown was never meant to handle that volume. We reshape the crown for positive drainage, install cricket diverters where needed, and use caps with deeper lids and wider overhangs to throw water clear of the masonry.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, day or night. We ask what you’re seeing, when it started, and whether you’ve had previous liner work. Russell Haines or one of our senior techs will often say: “Tell me what you’re seeing, and I’ll tell you what it actually means.”
2. 2
   Level-2 camera inspection on arrival. We run a camera up the flue, photograph the crown from the roof and the ladder, and check cap fit and condition. You see the photos. We explain what we found in plain English.
3. 3
   Parts decision. If your HeatShield system needs a factory-specific component, we source it. If a quality aftermarket part from Gelco, Famco, or Copperfield performs better for your setup, we explain the trade-off and let you decide. No surprises on the bill.
4. 4
   The repair. Crown work gets ground, bonded, and rebuilt or coated. Cap installs get proper standoff, storm collar, and fasteners into solid substrate, not brittle crown edge. We work clean and we work once.
5. 5
   Post-repair verification. We camera-check the flue again to confirm nothing shifted during the work. We water-test crown repairs with a controlled spray. Then we clean up.
6. 6
   Documentation and guarantee. You get photos, a written summary, and our 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.
