Firebrick joints are refilled with ASTM C199 medium-duty refractory mortar, the class the Florida code names.
- Free inspection and estimateEvery wall of the firebox in Lake Shore is tapped and probed cold, and the failed bricks and joints are marked at no charge.
- 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.
Mortar crumbs on the grate
Sandy grit on the grate or the firebox floor after a fire comes from somewhere above it. In a masonry firebox that is the joints between the firebricks, the softest part of the lining, giving up a little at a time. We start a firebox repair visit in Lake Shore by finding which joints are open, how deep the soft mortar goes and whether the bricks beside them still sit tight.
Open joints alone are a repointing job, and the estimate says so instead of reaching for a rebuild. Seeing grit on the grate in Lake Shore? Call (904) 920-5495 and we will look before the next fire.
Lake Shore lies within Duval County. Lake Shore does not reach the coast.

-
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.
An inland firebox that sits idle
A fireplace in Lake Shore that goes unused for months can still take water down the flue and collect debris on the firebox floor. None of that shows until someone looks with a light.
A cold inspection before the first fire finds open joints while they are still small.

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.
Raking out an open joint
Repointing a firebox joint means removing the failed mortar before new mortar goes in. The joint is raked to firm material with a hand tool, cleared of dust and loose grit, and dampened if the product's data sheet calls for it.
New refractory mortar is then packed in, struck flush and cleaned off the brick faces before it sets. Shallow skim coats over a soft joint break off with the first heat, so the raking is the slow, careful part of the job. A power grinder is avoided where it would chip the brick edges, since a chipped edge makes the joint wider than it was.
Temperature limits on the day of the repair
Mortar makers set weather limits for their products. One medium-duty refractory mortar is not to be applied when the temperature will drop below 40 degrees Fahrenheit within 48 hours, or onto frozen or frost-filled surfaces.
A firebox sits inside the house, but its masonry is tied to the chimney and cold air can come down the flue on a still night. On a cold day we check the product limits before starting and, where they cannot be met, move the repair to a better day instead of risking joints that do not cure. The ticket records the product and the date it went in.
Walls, joints and cure time in writing
- Cracked or hollow firebrick cut out and replaced one at a time
- Paint cleaned off wherever new mortar has to bond
- Back wall slope and throat height kept on any rebuild
- Hairline cracks left in place and noted for later checks
Firebox repair questions from Lake Shore
How long before we can use the fireplace after a firebox repair?
That depends on the mortar. One medium-duty refractory mortar needs at least 7 to 10 days before heat, and we write the exact date on the ticket. The first fire after that should be small.
What if the damper or smoke chamber needs work too?
Those go on the estimate as separate lines with their own prices. You can do them with the firebox repair or schedule them later.
