- 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.
Same-day looks at an open joint
An open joint you can see from the room is not an emergency in itself, but it does need a decision before the next fire. If a slot is open that day, a firebox specialist can look the same day you call and tell you whether it is safe to use in the meantime.
Keep fires out of it for a few hours before we arrive, since every wall has to be handled and probed cold. The repair itself is then booked around the mortar's cure time. Joint open in your Fruit Cove firebox? Ask for the next opening at (904) 920-5495.

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.
An inland firebox that sits idle
A fireplace in Fruit Cove 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.
10% off any service booked within 72 hours of inspection
Refractory mortar or new firebrick, either one comes 10% off.
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.
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.
Tapping and probing, wall by wall
Our firebox inspection for repair is done cold. Each firebrick is tapped with a hammer handle, since a sound brick rings and a loose one sounds dull. Each joint is probed with a pick to see how deep the mortar has gone soft or missing, and joint widths are checked against the quarter-inch limit.
Everything found is marked on the brick in chalk and written on the estimate under its wall: back, left side, right side and floor. The repair then covers the bricks and joints that failed and leaves sound ones alone, and you can walk the chalk marks with us before any work is booked.
Checked in Fruit Cove before any brick comes out
- Each firebox wall and the floor tapped, probed and marked in chalk
- Joint widths checked against the quarter-inch limit in R1001.5
- Back wall slope and throat height kept on any rebuild
- Hairline cracks left in place and noted for later checks
Before the first fire after a repair
Why not fill the cracks and paint over them?
Paint does nothing for the lining and keeps new mortar from bonding. Open joints need raking and refilling, and cracked bricks need replacing, so the repair lasts.
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.
