If your terracotta flue tiles have missing mortar joints, cracks, gaps, or surface deterioration, ceramic resurfacing is a strong, long-lasting repair option. Our FireGuard system creates a new, smooth, insulated ceramic coating inside your existing flue that can withstand temperatures up to 3,205°F.
This process seals gaps, restores structural integrity, improves draft, and is typically a more affordable alternative to a full stainless steel liner. It’s one of the best solutions for aging or damaged fireplace flues.
