This page is for Marietta homeowners who have a HeatShield fireplace that is acting up, whether it is a pilot light that will not stay lit, a firebox that is spalling, or a damper that has seized. Nathan Corliss and our crew have worked on enough HeatShield units in Cobb County to know exactly what fails and why.

How HeatShield Products Fail – and How We Fix Them

HeatShield builds a solid product, but nothing survives a Georgia fireplace forever. Here are the five failures we see most often in Marietta homes, why they happen, and what we actually do about them.

• HeatShield refractory panel cracking (the HeatShield Classic and Designer series). The refractory panels inside the firebox expand and contract with every burn cycle. After years of high heat followed by Georgia’s damp winters, hairline cracks turn into spalling, where the panel face literally flakes away. The panels are what protect the steel firebox behind them. Once spalling starts, moisture gets in and rust follows. We replace the panels with OEM-spec refractory material, not a generic patch, because a patch job shifts and cracks again inside two seasons.
• HeatShield gas log pilot assembly failure (common on the Radiant and See-Through models). The thermopile and thermocouple that keep the pilot light lit sit directly in the flame path. Over time, carbon buildup insulates them so they cannot sense heat properly. The result: the pilot lights, holds for ten seconds, then drops. Homeowners sometimes assume the gas valve is bad. Nine times out of ten, it is a fouled thermopile. We clean or replace the pilot assembly, test millivolt output, and confirm the valve is still good before recommending any bigger repair.
• Damper warping and seizing on HeatShield wood-burning units. Marietta summers run humid, and that moisture works its way down the flue and onto the damper plate. HeatShield’s cast-iron dampers are tough, but a damper that is never lubricated and sits in damp air for years will seize or warp. Homeowners notice the draft problem first: smoke rolling back into the room. We free, realign, or replace the damper assembly, then run a smoke test to prove the draft is moving the right direction.
• Glass door gasket failure on sealed HeatShield inserts. The woven gasket around the glass door degrades slowly, and most owners never notice until the glass starts sooting up unevenly or the fire burns lazy even with the air control wide open. A failing gasket lets uncontrolled air into the firebox, which throws off the burn and wastes wood or gas. We replace the gasket with high-temperature woven material, check the door latch tension, and confirm the seal with a dollar-bill drag test before we leave.
• Refractory mortar joint erosion in the firebox floor. HeatShield fireboxes are built with refractory mortar joints that are supposed to flex with thermal movement. In Cobb County, where winter fires are frequent and summer humidity is relentless, those joints erode faster than the panels themselves. You will see crumbling mortar and loose firebrick. We rake out the failed joint, repack it with high-temperature refractory mortar, and cure it properly so it does not crack on the first fire.
