- 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.
Heavy logs and the back wall
Logs tossed into the firebox land against the back wall or the floor, and over years that knocks at the lining. A chipped corner or a cracked brick low on the back wall can date from loading rather than from heat, and the pattern of damage usually shows which.
The repair is the same, a brick cut out and replaced, but knowing the cause helps it last, and we show you where the knocks landed. Setting logs in rather than dropping them saves the new brick. Chipped firebrick low in the back of your Nassauville fireplace? Phone (904) 920-5495 for a free look.

From a cold firebox to the first fire in Nassauville
-
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.
After a storm near the coast in Nassauville
Storms in hurricane season, June 1 to November 30, can drive rain down an open flue. A few miles from the water, Nassauville gets its share of that weather.
If water pooled in the firebox, we let it dry and trace the source before any repair.

What firebox brick is made to do
Firebrick is a different product from the face brick you see on the outside of a house. ASTM C1261, the specification for firebox brick in residential fireplaces, covers brick made from clay, fire clay or shale and fired until its particles bond, then tested for strength, for the heat it takes before softening, and for size and warp.
The Florida Building Code, in R1001.5, accepts firebrick meeting either C1261 or ASTM C27, the classification of fireclay and high-alumina refractory brick. When we replace a brick, the new one meets one of those two, and the ticket names which, so a later repair can match it.
Hydraulic and air-setting refractory mortars
Refractory mortars do not all harden the same way. A hydraulic refractory mortar sets and cures much like a portland cement mortar and, according to one maker, becomes water insoluble once cured. Premixed air-setting products harden as they dry, and some finish curing only when heat is applied.
Neither type is wrong in itself, but each follows its own data sheet for joint size, mixing, drying and first heat, and the two are not mixed in one joint. We choose by the joint width and the kind of repair, and the product name goes on the ticket so the next person to work on the firebox knows what is in the wall.
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.

Firebox repair questions from Nassauville
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.
Do you do firebox rebuilds as well as repairs?
Yes, where the backing masonry itself has failed as well as the firebrick. The rebuild keeps the code's wall thickness, the firebox depth and the throat height, and the estimate explains why a rebuild is needed.
