How a crown repair runs, step by step
When a precast crown makes sense
A precast crown is made off the roof and set on the chimney. Brick industry guidance says prefabricated tops generally perform better and are easier to make water-resistant than cast-in-place ones. They arrive cured, with their shape already formed.
Precast is not right for every chimney. The top must be measured carefully, including every flue opening, and the unit has to be lifted onto the roof safely. We explain whether your chimney suits a precast crown or whether forming one in place is the more practical route.
Giving the crown enough slope to drain
A crown must shed water, and slope is how it does that. The code calls for the top of a masonry chimney to be sloped. A flat or dished top holds water, which can then soak into the concrete and reach any crack.
Coating a flat crown does not add slope. We check how water leaves the top today, including any spots where it stands after rain. If the crown cannot drain, we explain replacement with a sloped shape. The exact fall is set on site to suit the chimney and its flues.
Keeping the flue liner above the crown
Each flue liner should stand above the finished crown. Brick industry guidance shows the liner projecting past the top of the cap. That keeps water on the crown from running into the flue and lets the sealant joint sit where it can be maintained.
When a crown is rebuilt, its height must still leave the liners projecting. We check this before forming a new top. A liner that is cracked or too short at the crown becomes a flue repair item, priced separately from the crown.
Crown work and water repellents for brick
A water repellent on the chimney brick and a coating on the crown are different treatments. The crown coating is a flexible membrane over the top. A repellent for brick soaks into the face and should still let the masonry release water vapor.
Brick industry guidance advises repairing cracks, joints and flashing before any repellent is considered, and waiting after repairs to see whether it is needed. We follow that order. The crown is repaired first, and brick waterproofing is discussed later as a separate item.
What the free crown inspection covers
- Bond break at each flue liner
- Firmness of the existing concrete
- Bond-break layer under new concrete
- Cap removal and reinstallation
What people ask about crown sealing
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.
Is a mortar wash on top of my chimney the same as a crown?
It sits in the same place, but a thin sloped mortar topping is not built like a formed crown. Brick industry guidance warns that thin, feathered edges are more prone to deterioration. We check whether yours can be coated or should be replaced.
Does the workmanship warranty cover crown repair in Little Havana?
Yes, the agreed crown work carries our workmanship warranty. Your written record states what was done, which helps if a question comes up later. Trouble from a separate part, such as a failed cap or flashing, is discussed as its own item.
