The mortar's cure time goes on the ticket, so the first fire after the repair waits until it is ready.
- Free inspection and estimateEvery wall of the firebox in Lakeside 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.
Repoint, replace or reline
Firebox repair comes in three sizes, and the estimate says which one each wall needs. Open joints in otherwise sound brick are repointed. Bricks cracked through or worn thin are replaced one at a time. A wall worn across its whole face, or pulling away from the masonry behind, is relined.
Each wall is priced on its own line, so a sound side wall is not rebuilt because the back wall failed, and you can see the size of each job before choosing. Not sure how big a job your Lakeside firebox is? Local specialists check it free at (904) 920-5495.
Lakeside falls within Clay County. The 2020 Census count for Lakeside was 31,275 people.

How our firebox pros repair a fireplace in Lakeside
-
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.
Settled houses and firebox cracks in Lakeside
A crack that runs through several firebricks and their joints in a straight line points to movement, not only heat. Inland or coastal, that kind of crack gets the backing masonry checked.
On a visit in Lakeside we follow such a crack to see whether it continues into the walls around the fireplace.

What medium duty means on a mortar bag
The Florida code asks for firebrick to be laid in medium-duty refractory mortar conforming to ASTM C199. That standard is a pier test: brick is laid up with the mortar, heated, and checked to see whether the mortar has run out of the joints.
One maker of a medium-duty product states that its mortar passed at 2,550 degrees Fahrenheit for at least six hours, and puts ordinary mortar at about 600. That gap explains why a bag of regular mortar used as a firebox patch breaks down after a few fires. We read the bag for the C199 classification before anything goes into a joint.
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.
The firebox floor and the hearth under it
Under the firebrick floor of the firebox is the hearth, which the Florida code requires to be at least 4 inches thick and built of concrete or masonry on noncombustible support. A floor brick that sinks or rocks may point to a bed that has eroded or a hearth that has cracked beneath it.
We lift the failed floor bricks, check the bed and the hearth below, and reset the floor flat in refractory mortar. Cracks in the hearth slab, or in the extension that runs out in front of the opening, are written up as hearth work, which has rules and a price of its own.
Checked in Lakeside before any brick comes out
- Joint widths checked against the quarter-inch limit in R1001.5
- Floor firebricks lifted, rebedded and reset flat
- Water marks traced to their source and listed separately
- Smoke chamber, damper and hearth items kept on their own lines
Before the first fire after a repair
Is refractory caulk good enough for firebox joints?
Not for every joint. Florida's code wants firebrick laid in C199 medium-duty refractory mortar, with joints kept to a quarter inch. We read the product's stated standard and joint range before using it.
Is the inspection really free?
Yes. The firebox check and the written estimate cost nothing, and the pricing is upfront with no hidden fees. Book the repair within 72 hours of the check and 10% comes off.
