A home inspector flagged the firebox

Buying or selling a house often brings a report line such as "firebox mortar joints deteriorated" with no detail behind it. A line like that is where our visit starts. We check each wall and the floor of the firebox, mark the joints and bricks that failed, and put each one on the estimate with the repair that fixes it.

Both sides of the sale then have a written scope instead of a guess, with the materials named. Firebox noted on an inspection report in Mayport? Call (904) 920-5495 and give us the closing date when you book.

Within Jacksonville city limits, Mayport is its own named neighborhood. Mayport is part of Duval County.

Reading the label on a tub of fireplace cement

Tubs of premixed fireplace cement are sold for firebrick repair, and their labels are worth a close look. One widely sold premixed refractory cement is rated to 2,000 degrees Fahrenheit and lists ASTM E136, a test of whether a material burns, rather than the C199 pier test. It is also made for joints of a quarter inch or less, with a sixteenth of an inch as its minimum.

A product like that has its place, but it is not automatically the medium-duty mortar R1001.5 calls for between firebricks. We compare each product's stated standard with the code before choosing it for a joint.

Why fresh mortar waits days for a fire

Water goes into a joint with the mortar, and that water has to leave before the mortar sees a flame. One medium-duty maker calls for a minimum of 7 to 10 days before heat is applied, and says a mortar that is not fully dry will crack from the pressure of water turning to vapor inside it.

Drying also depends on the job conditions, the temperature and the air in the room, so the date on the ticket is a minimum, not a promise that a thick joint is ready. We write it down before leaving, and the first fire after that date should be a small one.

Replacing a single firebrick

Replacing one firebrick starts with cutting the joints around it without disturbing its neighbors. The old brick comes out in pieces if it must, the opening is cleaned back to sound mortar and the dust is cleared out.

The new firebrick is cut to size and set in a full bed of medium-duty refractory mortar on every side, with joints no wider than the code allows and its face flush with the wall around it. A neighbor that loosens during the work is reset in the same visit and added to the ticket, so no brick is left rocking beside a new one.

Checked in Mayport before any brick comes out

Each firebox wall and the floor tapped, probed and marked in chalk
Open joints raked to firm mortar and repointed in C199 refractory mortar
Worn walls relined, with the firebrick thickness stated
Floor firebricks lifted, rebedded and reset flat

Before the first fire after a repair

Can you replace just the bad firebricks in Mayport?

Yes. Cracked, hollow or worn-through firebricks come out individually and new ones go in, and the sound bricks around them stay. A full reline is written up only when a whole wall has worn.

Will new firebrick match the old color?

Close, though not exact. Firebrick color varies by maker and batch, and the old lining has darkened with use, so new bricks look lighter at first. We tell you before ordering.
