How HeatShield Products Fail - and How We Fix Them

• Cerfractory Flue Spray liner shrinkage in the UL-1777 listed system. Towson’s freeze-thaw cycles, especially in older homes near Goucher College with unlined exterior chimneys, accelerate the hairline shrinkage that HeatShield’s spray-applied liner can develop after 8-12 years. We camera-inspect to confirm the gap pattern, then re-spray with HeatShield-compatible Cerfractory material or recommend a stainless DuraFlex liner if the flue is too far gone for a reliable re-coat.
• Factory-built fireplace firebox floor cracking in the HeatShield FB series. These units ship with refractory panels that can’t handle thermal shock when homeowners burn green oak or overfill the box. We source OEM HeatShield panels when available, but we’ve also found that Gelco’s 2300°F refractory substitute outperforms on thermal cycling and costs less - we show you both options before ordering.
• Gas insert venting faults in the HeatShield GI line. The flexible aluminum vent connectors degrade at the elbow where they penetrate the masonry, particularly in Towson’s humid summers when condensation accelerates corrosion. We replace with factory-spec flex or upgrade to a rigid DuraFlex direct-vent run if the routing allows, and we always pressure-test the gas valve assembly before we leave.
• Damper hardware seizure in HeatShield wood-burning units. The cast-iron throat dampers on HWB-series fireplaces corrode at the pivot pin when homeowners skip annual sweeping and acidic creosote accumulates. We free the mechanism, replace the pin with a stainless equivalent, and document the flue condition so you know whether the root cause is a drafting problem or just deferred maintenance.
• Refractory mortar joint failure at the smoke chamber. HeatShield’s parging-grade mortar can slough off in the corbelled smoke chamber of pre-1990 Towson colonials where the original builder skimped on clearance to combustibles. We re-parge with HeatShield-compatible refractory mortar rated to 2550°F, or we install a stainless smoke chamber liner if the corbelling is too degraded to hold a new coat.

Our HeatShield Fireplace Services Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing or smelling, and books a window. No app, no callback queue.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, runs a video scan of the flue and firebox, and shows you the footage on a tablet. You get a plain-English verdict, not a sales pitch.
3. 3
   Parts decision with options. If it’s a HeatShield component, we check OEM availability and quote a quality aftermarket alternative when it makes sense - Gelco refractory, DuraFlex liner, or Famco hardware. You choose; we don’t choose for you.
4. 4
   The repair, documented. We complete most HeatShield fireplace repairs in one visit. The technician photographs before, during, and after, and leaves the images with you.
5. 5
   Test and sign-off. Gas units get a pressure test and combustion analysis. Wood units get a draft test and smoke-pencil check. We don’t leave until the system performs.
6. 6
   90-Day Done Right Promise in writing. If something’s not right, we come back. No paperwork to file, no argument. That’s the Keystone Standard.
