The steps of a firebrick replacement
Rust streaks running down the back wall
Orange or brown streaks on the upper back wall usually come from metal above, most often the damper plate or frame. Moisture carries the rust down across the firebrick.
The stain itself does little harm to the brick. It is the moisture and the rusting metal that need attention. We check the damper and note where the water may be coming from. Firebox joints near the streaks are checked for softening, and any repair to them is listed apart from the damper work.
Why the back wall usually wears first
The back wall sits closest to the burning wood and takes the most radiant heat. It is also the wall that deflects heat into the room, so it works at full load during every fire.
Spalled units and open joints on the back wall are therefore common before the sides show wear. We check whether the damage is limited to the back or spreading, and whether the back wall's upper slope still supports what sits above. The repair plan follows from that.
The top courses just below the damper
The highest courses of the firebox sit just under the throat and the damper. They take rising heat, any water that runs past the damper, and the weight of what sits above. Loose units here can affect how the damper seats.
We check those courses closely, often with the damper open and a light. Repairs at the top of the firebox are planned with the damper in mind, so its frame stays supported and its plate still closes. Any damper repair that follows appears as a separate item.
Water-damaged fireboxes in Hollywood
When water has been reaching a firebox in Hollywood, we note the soft joints, rust streaks and damp debris. We also name the chimney service that traces the leak. Rust streaks under the damper and grit collecting on the floor are the usual signs.
The firebox repair is best scheduled after the source is stopped. New refractory mortar should stay dry until it is heat cured, so a repair under an active drip would not last. Once the leak is stopped, the softened joints are raked and repointed, and the curing plan is explained.

What people ask about firebox rebuilds
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.
Do you repair the floor inside the firebox?
Yes. The floor inside the opening is part of the firebox and takes heavy wear from grates, logs and tools. Loose or cracked floor units are reset or replaced in refractory mortar, and the grate is checked at the same time.
Do you arrange firebox repair throughout Hollywood?
Yes. We book a free inspection at a time that suits you, identify the lining and explain the findings. A free written estimate follows, and work starts only after you approve it.
