Crown repair decisions explained plainly
Forming a new crown in place on the chimney
A cast-in-place crown is built on the chimney. Forms are set around the top, reinforcement is placed, and concrete is poured and shaped. The finished crown should slope away from each flue and overhang the brick with a drip.
Brick industry guidance asks a cast crown to keep the same thickened shape as a precast one, rather than thinning out toward the edge. We explain the shape planned for your chimney before work begins. Exact dimensions follow the construction and the applicable requirements, so they are confirmed on site.
Why the crown should project past the brick
A crown that stops flush with the brick face lets water run straight down the chimney. An overhang carries the water out beyond the face before it drops. That keeps the top courses of brick drier after every rain.
When a crown does not overhang, brick industry guidance suggests forming a drip another way, such as corbeled brick below it. On a new crown we build the overhang into the shape. On an existing one, we explain whether its projection is adequate or part of the reason the brick below is wet.
Crown pieces found on the roof or in gutters
Small pieces of concrete near the base of a chimney can come from the crown edge. They break away where the concrete is thinnest or where water has worked into cracks. Sometimes they collect in gutters and go unnoticed for a while.
Keep the pieces if you find them and mention where they landed. Their size and shape tell us something before we even reach the roof. Keep people away from the area below the chimney if pieces are still falling, and tell us so we can plan the inspection with that in mind.
Straight cracks across the middle of the crown
A single straight crack across a crown often follows a line of stress from shrinkage or movement. It may be fine and stable, or it may widen over time. The difference shows in its edges and whether the concrete on both sides is still firm.
We look at the crack width, whether the sides sit level with each other and whether water has stained the brick below it. A stable crack in sound concrete may be filled and coated. A crack with one side lower than the other points to movement and a different repair.

Crown repair answers for Coral Terrace
Does crown repair include the seal around the flue tiles?
It should. The residential code calls for a caulked bond break where each flue liner passes through the crown. We check that joint, remove failed sealant and reseal it with a suitable elastomeric product as part of the agreed crown scope.
Do I need to be home while you work on the crown?
Not always. We need access to the roof and a clear area below the chimney. Tell us about gates, pets or parked cars. We walk you through the findings before work starts and again when the job is finished.
How does the inspection discount apply to crown repair?
Approve crown work in the 72 hours after your free inspection and a 10% discount applies to it. The window runs from your own inspection, and it covers any service on the estimate you book in that time.
