Refractory Panels. We service refractory panels in Muncie, Marion, Indiana and surrounding areas. Refractory panels are the inside lining to a prefabricated or zero clearance fireplace. When these develop cracks around 1/4″ or large enough for a coin to fit in, they need to be replaced prior to fireplace use. We repair fireboxes by sealing up holes and filling gaps and cracks with strong, fire- and moisture-resistant refractory mortar. We also replace and repair refractory panels and firebrick so your entire firebox is free of creosote buildup, openings, and damage that could threaten your safety and enjoyment of the fire.
