Sealing a sound crown or replacing a failed one
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.
Shrinkage cracks in new crown concrete
Concrete shrinks as it cures. Brick industry guidance treats shrinkage of a cast-in-place crown as a certainty and calls for reinforcement to help control it. Fine cracks on an older crown may date back to that original cure.
We explain the difference between old shrinkage lines and cracks that are active and growing. On a new crown, reinforcement and curing care are part of the plan. If you notice fine lines on a new crown later, tell us so we can look at them against what was expected.
Rescheduling crown work around rain
Coatings need a dry surface and dry hours afterwards. Fresh concrete also needs protection from heavy rain while it sets. Both depend on the weather on the day, not the forecast from last week.
If rain threatens, we may protect the work with sheeting or move the date. We contact you as early as we can when a change is needed. A short delay is better than redoing a coating that washed off or a crown surface that was pitted by rain.
When the crown problem is really a rebuild
Sometimes the crown is only the most visible failure. The top may be leaning, courses may be loose or the masonry may have separated from the house. A new crown alone will not make that sound. Those are structural questions.
We explain when crown repair is enough and when the chimney top needs rebuilding first. A crown formed on loose brick can crack again as the masonry moves. The rebuild, if needed, is described and priced as its own job, and the crown is planned as part of that work.

Chimney crown work, questions and answers
Can a crown with fine cracks be sealed rather than replaced?
It can, when the concrete around the cracks is firm and the crown still sheds water. A crown coating goes on a clean, dry and sound surface. If the top is loose, hollow or flat, sealing only hides the fault, so we explain replacement instead.
Why does a new crown need to overhang the brick?
An overhang with a drip edge throws water clear of the brick face instead of letting it run down the chimney. The code also calls for a drip edge on the top of a masonry chimney. Without one, water can keep soaking the top courses.
What should I tell you when I call about the crown?
Mention what you have seen, such as concrete pieces on the roof, a stain inside or cracks visible from the yard. Tell us about earlier patches or coatings and any appliance that vents through the chimney.
