How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with inadequate crown slope. The foam liner cures to a hard, ceramic-like surface, but we’ve seen dozens in Riverside and Avondale where the original mason poured a flat crown that pools water right at the liner termination. Water migrates behind the foam, freezes on our handful of hard freeze mornings, and pops the liner edge. We re-pitch or rebuild the crown with proper drainage, then seal with a vapor-permeable crown coat that won’t trap moisture against the Cerfractory surface.
• HeatShield ProLiner multi-flue caps with corroded base rails. The ProLiner cap is a solid piece of hardware, but the 304 stainless base rail sits in condensate and acidic flue gas if the flue is oversized for the appliance. In Jacksonville’s salt air, especially within a few miles of the St. Johns River or the Intracoastal, that rail can pit through in six to eight years. We source replacement base rails from HeatShield-compatible fabricators or fit a Gelco cap with a heavier 316 stainless base if the flue sizing allows.
• HeatShield UL Listed relining jobs where the cap was never upgraded. The old cap stays on because nobody told the homeowner it needed changing. The original cap’s mesh is too fine for the new liner’s draft characteristics, or the lid sits too low and traps heat. We see this in San Marco bungalows where a liner was sold as the whole solution. We measure draft and temperature at the flue collar, then spec a cap with proper clearance and mesh sizing for the HeatShield liner that’s actually installed.
• HeatShield factory-sealed crown coatings applied over active cracks. The HeatShield CrownCoat product works when the substrate is sound, but we’ve peeled it off crowns in Arlington where the crack was structural, not surface. The coating held for two seasons, then the crack propagated underneath and the coating delaminated in sheets. We grind out the crack, assess whether the crown is salvageable, and only then apply a compatible coating or pour a new cast-in-place crown.
• HeatShield single-flue caps with storm-lifted lids on older Jacksonville chimneys. The cap’s lid is held by set screws or a friction fit, and after fifteen years of afternoon thunderstorms, the fasteners fatigue. The lid lifts, rotates, and the next wind deposits it in your yard or your neighbor’s oak canopy. We inspect the flue tile for impact damage, replace the cap with a through-bolt or clamp-ring model, and if the flue tile is cracked, we discuss a HeatShield compatible flue top repair before the new cap goes on.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing, and books a time that works. Most HeatShield cap and crown calls in Jacksonville go on the schedule within 24 to 48 hours.
2. 2
   Level-2 camera inspection. Our technician arrives uniformed and background-checked, sets up the camera, and documents the flue, the liner termination, and the crown condition. You see the photos. We give you a plain-English verdict on whether the problem is the cap, the crown, or both.
3. 3
   Parts decision. If it’s a cap replacement, we check whether your HeatShield liner or existing cap size still has OEM availability. If lead times are long or the part is obsolete, we source a quality aftermarket cap from Gelco or Famco that maintains proper clearances and draft. For crown work, we match the repair material to your HeatShield system, never using generic mortar that cracks in the first freeze-thaw cycle.
4. 4
   The repair. Most HeatShield cap and crown jobs finish in a single visit. We protect your roof and landscaping, remove the old hardware, address any flue tile or liner edge damage, install or coat, and test fit.
5. 5
   Draft and water test. We run a smoke pellet to confirm the cap isn’t restricting draft, and we water-test the crown with a controlled spray to verify no penetration at the liner collar or flue tile joints.
6. 6
   Cleanup and documentation. We leave the site cleaner than we found it. You get photos, a written description of what was done, and the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.
