Damper & Firebox Repair
Fix stuck dampers and cracked fireboxes for a fireplace that works safely and efficiently.
A damper that will not seal wastes energy year-round, and a cracked firebox can let heat reach combustible framing. We repair and replace throat and top-sealing dampers, rebuild fireboxes with refractory brick and mortar, and replace worn smoke shelves and lintels so your fireplace is safe to enjoy.
