Brick, mortar and the cause behind the crack
Exposed holes in cored bricks
Many modern bricks have holes, or cores, through their center. Laid in a wall, the cores are hidden. Where bricks are cut or stepped back at a shoulder or the top, the cores can be exposed and fill with water.
The brick industry's chimney guidance recommends a solid surface where masonry steps back. We look for open cores on shoulders, ledges and the top courses. Closing them with a proper surface, or replacing cut units with solid ones, stops that water reaching the joints below.
Framing too close to chimney masonry
The Florida Building Code keeps combustible materials a set distance from a masonry chimney and requires fireblocking where it passes floors and ceilings. Renovation work sometimes brings framing, trim or insulation right up against the masonry.
We look for that during attic and interior checks. Correcting a clearance problem may involve another trade, and we explain what it means for using the fireplace. The finding is listed separately from the masonry repair, so it does not get lost in a long estimate.
What the free masonry inspection can show
Our free inspection covers the brick and mortar we can reach and see safely. That means the stack from the ground and the roof, the attic side where accessible and the chimney breast indoors. We note cracks, loose units, eroded joints and signs of water.
Some things stay hidden, such as the condition of masonry behind a finish or deep inside a joint. We say what the visit could not confirm and how that could affect the scope. The written estimate records both what was seen and what was not.
Wetting one face to confirm a masonry leak
Where it is needed to confirm a leak through the brick, we wet the masonry with a hose, one area at a time, while someone watches inside. We start low on the chimney and work upward, so each area is tested on its own.
Most masonry visits do not need a test, because the damage and the water path are clear. We explain beforehand which area will be wetted and what we hope to learn. A clear result can narrow the repair to the joints or units that actually let water in.

Questions about chimney brick repair
Why did an earlier masonry repair on my chimney crack again?
Common reasons are water still reaching the masonry, continued movement or a repair mortar harder than the brick. We look for the reason before repeating anything, so the new repair addresses it.
Why do you ask about earlier repairs to the chimney?
Earlier work explains a lot. A patch in hard mortar, sealant over cracks or a repair that failed quickly all change what we look for and how the new repair should be done.
Do you test for water entry before repairing brickwork?
When the job calls for it, a hose water test on one area at a time can confirm where water gets in. Most masonry visits do not need one, and we explain when it would help.
