Why crowns crack at the flue corners
Cracks that start at the corners of the flue tile and run outward to the edge of the crown tell a specific story. The tile heats, grows and pushes against the crown, and a crown with no bond break has nowhere to relieve that push but through the concrete.
Sealing those cracks on your Bayard crown without dealing with the joint at the tile leaves the cause in place. The repair either opens a proper bond break around the tile or, if the crown is too far gone, replaces the crown with the bond break built in. Cracks on top of your Bayard chimney? Our masons inspect crowns for free, so call (904) 920-5495.
Bayard is a neighborhood inside Jacksonville city limits. Bayard sits in Duval County.

From crack map to cured crown in Bayard
-
Crack map from the roof
We identify the type of top and sketch each crack with its width, so the choice between coating and recasting is based on what is there.
-
Prep for coating or removal
A sound crown is cleaned and its wider cracks filled; a failed one is broken out down to sound brick.
-
Coat, or form and pour
The coating is brushed on in dry weather, or new concrete goes into forms with an overhang, a drip groove and reinforcement.
-
Cure, seal and refit the cap
The bond break at each flue is sealed, the concrete cures under cover, and the cap goes back on.
Cure time for new crowns in Bayard
Concrete gains strength slowly and needs to stay damp while it does. A crown cast on a sunny roof in Bayard can dry out too fast and craze on top.
After the pour we cover the crown and keep it damp, and the estimate tells you how long before the cap goes back on and the fireplace can be lit.

Building the forms for a cast crown
A cast crown is shaped by its forms. Boards or form material are fixed around the top of the chimney, set out past each face by the planned overhang and level all the way round. A strip fixed to the underside of the form creates the drip groove.
Inside the forms, the top surface is shaped to slope from the flue tiles down to the edge on every side. The forms stay on until the concrete can hold its shape, and they come off without breaking the edge. The forms decide whether the finished crown sheds water or sits up there as a lump of concrete.
The drip groove under the overhang
Water running off the edge of a crown wants to curl back along the underside and run down the brick face. A drip groove, a small channel cast into the underside of the overhang, breaks that film of water so it drops clear of the chimney.
The groove sits near the outer edge of the overhang, and it has to run continuously around all four sides. A groove that stops short at a corner lets water find its way around the end. A drip edge is one of the crown requirements in R1003.9.1, and the groove is how a cast crown provides it.
What goes into the bond break at the flue
The bond break is the flexible joint between the crown and each flue tile. It lets the tile grow with heat without pushing on the concrete. The code calls for it to be caulked, following ASTM C1283, and the BIA detail shows a backer rod with sealant over it.
In practice we wrap the tile with a compressible material before the concrete is placed, then rake the top back and fill it with a primed backer and a sealant suited to heat and weather. The finished joint stays flexible. A crown poured tight against the tile, with no gap at all, is the fault this detail exists to prevent.
Coat or recast, and the reasons
- Repair method chosen, coating, patch or recast, with the reason
- Coating product class and the data sheet's weather window
- Flue tile height above the finished crown
- Chimney cap removal and reinstallation, with how it is fastened
Crown repair questions from Bayard
Can a drip edge be added to my existing crown?
Not in a way that lasts. A drip edge has to be formed into the underside of an overhang, and a crown without an overhang has nowhere to put one. The fix is a new crown formed wider than the chimney.
Is there 10% off crown work?
There is. Crown coating or recasting booked within 72 hours of the free inspection comes 10% off; mention it when you book.
