Local firebrick repair or a full firebox rebuild
When a moving firebox loosens the damper frame
The damper frame usually rests on the top of the firebox walls. If the back or sides have shifted, the frame can loosen, tilt or crack its mortar bed. A damper that suddenly binds may be telling you about the firebox below it.
We check the top courses and the damper seat together. Resetting the frame in its bed is part of a firebox rebuild at that level. If the damper plate itself is damaged, that repair sits with our damper service and appears as its own line.
The firebox floor takes the most abuse
The floor of the firebox, sometimes called the inner hearth, carries the grate, the logs and the tools. Dropped logs chip it, grate legs grind into it and ash shovels scrape its joints. Its units often loosen before the walls do.
We check each floor unit for movement and each joint for loss. Loose floor bricks are lifted, their bed cleaned and the units reset or replaced in refractory mortar. The floor inside the opening is firebox work; the hearth extension in front of the opening is a separate repair.
Cracks that run beyond the firebox
A crack that starts in the firebox and continues across the face, up the wall or into the hearth is not a lining problem alone. It may reflect movement in the fireplace structure or its base.
We trace such a crack as far as we can see it. If it points to structural movement, we explain which further assessment is needed and hold the lining repair until that is understood. Relining over a moving structure would crack again along the same line.
When the damage continues above the damper
Rough, crumbling masonry above the damper belongs to the smoke chamber rather than the firebox. The code calls for that chamber's interior to be parged smooth with refractory mortar.
If our firebox inspection shows the damage continuing upward, we say where the firebox ends and the smoke chamber begins. Smoke chamber work is its own service with its own materials. The estimate keeps the two apart so each is priced and scheduled on its own. Where both need work, we suggest an order, since smoke chamber work drops debris into the firebox.

Asked about firebox repair in Washington Park
Can you replace only the firebricks that are damaged?
Often, yes. Where the rest of the lining is sound, we cut out the failed units and set new firebrick in thin refractory joints. If damage runs across whole walls, we explain why a rebuild of that wall may last longer.
What should I do with bricks that have fallen out?
Leave them on the firebox floor and keep fires out until the lining is checked. The pieces show where the failure started. They are not set back in, because a unit that has failed once is not reused.
What goes into the written record for firebox work?
The walls and areas repaired, the units replaced, the joints repointed, the mortar product and the curing steps still to follow. It also notes anything we saw but left as it was.
