- Upfront pricing, no hidden feesEach wall is quoted for what it needs, a few joints, a few bricks or a full reline, so a small repair stays small.
- 100% satisfaction guaranteedIf a joint we repointed opens again after it has cured and been used as the ticket says, we come back and redo it.
Before the first cool evening
The first fires of a cool spell are when a worn firebox tends to show what it has been doing since the last season. A look at the joints and bricks before then gives time for a repair to cure, because refractory mortar needs days, not hours, before it sees heat.
We write the cure time from the mortar maker's data on the ticket, so the first fire lands on a date the repair can take. The inspection costs nothing. Want the fireplace in San Jose ready for the first cold night? Book it now at (904) 920-5495.
The coastline lies beyond San Jose. San Jose is one of the named neighborhoods of Jacksonville.

How firebox repair runs
-
Keep the firebox cold
Let the fireplace go unused for several hours ahead of our visit, so each wall is cool to the touch.
-
Tap, probe and mark
Each brick is sounded, each joint probed, and the failed ones marked and written up by wall.
-
Rake, rebrick or reline
Joints are raked and repointed, failed bricks replaced and worn walls relined in C199 mortar.
-
Cure date on the ticket
The mortar maker's drying time sets the date of the first small fire, written down before we leave.
Wet ash and the firebox floor
Ash left in the firebox between seasons soaks up water that comes down the flue and holds it against the floor bricks, even in an inland town like San Jose.
We clear the ash, let the floor dry and repoint the joints once they are dry.

Refractory mortar or new firebrick, either one comes 10% off.
Mixing refractory mortar for a repair
Hydraulic refractory mortar is mixed with clean water only. One maker says no bonding agent is needed, that high-speed mixing should be avoided because it traps air, and that mortar which has stiffened is thrown out instead of being loosened with more water.
The same maker gives a working time of about an hour, shorter in warm weather, and suggests cold water on hot days to slow the set. On a firebox repair that means small batches mixed as the joints are ready, rather than one large batch that goes stiff halfway along the back wall and tempts someone to add water.
Room for the firebox to expand
Masonry grows slightly as it heats and shrinks as it cools. The Brick Industry Association recommends a 1-inch space between the combustion chamber wall and the backup masonry, held open with a compressible noncombustible fibrous insulation, to give that movement room. The building code does not require it.
When we rebuild a firebox wall from the backing out, we raise that option with you before the work starts. On a lining repair the existing construction stays as built, and we note it when a lining mortared hard to its backing is cracking in a pattern that points to movement rather than wear.
Factory-built fireplaces are another repair
Molded refractory panels in a metal body mark a factory-built fireplace, a unit tested and listed with its own chimney pipe. Those panels are replaced with the replacement panels listed for that model, not with laid firebrick and mortar.
The quickest way to tell the two apart is the rating plate, which a factory-built unit carries and a masonry firebox does not. When the fireplace proves to be factory-built, the work is written up as prefab fireplace repair, a separate service with its own parts list, and the masonry firebox rules on this page do not apply to it.
Checked in San Jose before any brick comes out
- Cracked or hollow firebrick cut out and replaced one at a time
- Joint widths checked against the quarter-inch limit in R1001.5
- Damper frame supported and reset when the back wall is rebuilt
- Product name and standard of every mortar and brick used
Before the first fire after a repair
Can you replace just the bad firebricks in San Jose?
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.
Should I stop using the fireplace until the repair?
If bricks are loose, joints are open deep into the wall or the back wall bows, yes. Hairline cracks in sound brick can wait for the visit, and we tell you which you have. Call (904) 920-5495 to book a free inspection in San Jose.
