How firebox damage is found and fixed
Cracked bricks on the firebox floor
The floor of the firebox takes the weight of the grate, falling logs and the heat from the coals. Cracked or broken floor bricks are common, and a gap in the floor lets heat reach the hearth construction below.
Our crew lifts damaged floor bricks, checks the bed underneath and relays new firebrick in refractory mortar, level with the rest of the floor. We check the joint where the floor meets the walls at the same time, since that corner often opens too.
Mortar for laying brick, patch for small repairs
Laying or resetting firebrick calls for refractory mortar with thin joints. Filling a small chip or a shallow void in otherwise sound brick is a different task, sometimes handled with a refractory patching product.
We use each product for the job it was made for. A patch never stands in for a missing brick, and the estimate tells you which parts of the firebox get new brick, which get new joints and which, if any, get a patch.
Firebox repairs backed by our workmanship warranty
The firebox repairs our crew makes are covered by our workmanship warranty. Materials carry whatever warranty their makers give, and we note the products used on your job sheet.
If our repair does not hold when the fireplace is used as the job sheet describes, call us. We come back, check the work and make it right. That promise comes with our 100% satisfaction guarantee on every job in Merrimac.
A painted or coated firebox interior
Some fireboxes have been painted or coated to freshen their look. Paint can hide cracks and eroded joints, and some coatings peel or blister when heated.
Our technicians check under any coating for the brick and joints beneath. If loose coating needs to come off before a repair, the estimate says so. We do not recommend painting over a damaged lining in place of repairing it.
Reporting new cracks after a repair
If a crack or loose material appears after a repair, note exactly where it is. Its position tells us whether it sits in the repaired area or in another part of the firebox.
Call us and we come back to look. Work in the repaired area is covered by our workmanship warranty, and anything new gets the same free inspection and written estimate as the first visit.

Asked before a firebox repair
Why can't ordinary mortar be used inside the firebox?
Ordinary mortar is made for normal temperatures and can crumble after repeated fires. The Florida residential code calls for firebrick to be laid with medium-duty refractory mortar, and that is what our crew uses.
