Damper & Firebox Repair
Seized dampers freed or replaced and cracked fireboxes rebuilt so the fireplace closes tight and burns safely.
Humidity is hard on cast-iron throat dampers, and by the time a homeowner in Monroe or Hickory calls, the plate is often rusted open or shut and the firebox behind it has open joints in the firebrick. We free or replace the throat damper, or fit a top-sealing damper at the cap that closes on a gasket and keeps conditioned air in the house. Firebox joints are repacked with refractory mortar, and the panels in factory-built units are swapped when the camera shows cracking wider than a hairline.
