How we approach crown repair in The Roads
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.
Caulk spread over crown cracks is not a repair
Brick industry guidance observes that caulking is often used to hide poor workmanship rather than as a planned part of construction. On chimney tops that shows up as sealant smeared along cracks across the crown. It may slow water briefly and then peel.
We remove surface smears before assessing the concrete underneath. Sealant has one proper job on a crown, which is the flexible joint at each flue. Cracks across the surface call for a coating on sound concrete or for replacement. We explain which one applies.
When a new crown is more than you need
The opposite mistake happens too. A crown with fine surface cracks and good slope does not always need to be torn out. Replacing a sound crown adds cost and disruption without improving how the top sheds water.
If your crown is firm and well shaped, we tell you so. A coating, resealed flue joints or a small edge repair may be enough. We explain the reasons behind a limited scope just as carefully as we would explain a full replacement.
Coating a newly formed crown
A new concrete crown does not always need a coating. A well-formed crown with slope, overhang, drip and sealed flue joints sheds water on its own. Some owners still ask for a coating as extra protection.
If you want one, we explain what the product adds and when it can be applied after the concrete has cured. The coating is listed as its own item. We would rather tell you it is optional than add it to every job without a reason.

- Elastomeric crown coating where suitable
- Formwork for a cast-in-place crown
- Bond-break layer under new concrete
Chimney crown questions we hear
Will a new cap stop water coming through the crown?
No. A cap covers the flue opening, while the crown covers the masonry around it. Water that enters through a broken crown keeps entering under a new cap. We check both parts and price each one on its own line.
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.
Should I ask about the crown if the fireplace is never used?
Yes. The crown keeps rain out of the masonry whether or not you light fires. Water entering an unused chimney can still damage brick, the flue and nearby ceilings. A free inspection tells you whether the top needs attention.
