The crown repair options we weigh with you
The brick courses right under the crown
The top few courses of brick take water from any crown that fails. Their joints may wash out and their faces may flake. Once the old crown comes off, their condition is much easier to see.
We tell you before removal that the top courses will be assessed, and what happens if they are loose. Relaying or repointing that brick is masonry work with its own line on the estimate. We stop and explain before adding it, so the crown price does not grow without your approval.
Layers of old patches on a crown
Some crowns carry several patches from different visits. Each layer may be a different material, and they do not always bond to each other. Water can travel between layers and appear somewhere unexpected.
Tell us what you know about earlier crown work, even if it is only a rough idea. We assess whether the layers can stay or need to come off. A new product applied over a stack of failing patches can only perform as well as the weakest layer underneath it.
Coordinating crown work with roof work
Crown repair and roof replacement both happen at the top of the house. The order matters. New roofing damaged by crown removal, or a new crown disturbed by roofers, means repeat work for someone.
If roof work is planned, tell us the timing. We explain whether the crown should be done before or after, and how the two trades can avoid working over each other. The flashing where the chimney meets the roof often sits between the two jobs, so we clarify who handles it.
Crown debris falling inside the chimney
Pieces of a failing crown do not always fall outward. Some drop into the flue and land on the smoke shelf or damper. You may hear debris or find gritty fragments in the firebox.
Mention anything like that when you call. We check the top for missing sections and, where needed, look at what has collected below. Clearing that debris can be included in the crown work. Any damage it caused lower in the chimney is explained separately.

Answers about chimney crown work
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.
Can I coat the crown myself with a product from the store?
A crown coating only works on firm, clean and dry concrete, and it cannot hold loose pieces together. Roof work also carries real risk. If you are considering it, ask us first whether your crown is a suitable surface for any coating.
How is debris from the old crown handled?
Broken concrete is lowered from the roof with care, and the work area is cleaned. We haul the debris away. Should the job pause with the chimney top open, we fit a cover over it before leaving and keep it there until work resumes.
