Firebox & Damper Repair questions

Before you book

What is a top-sealing damper?
A damper mounted at the top of the flue with a rubber seal, operated by a cable from the firebox. It closes tighter than a cast iron throat damper and keeps rain and animals out as well.
Can I use regular mortar in the firebox?
No. Fireboxes need refractory mortar and firebrick rated for the heat. Regular mortar breaks down quickly in a fire.
