Crown repair choices for homes in Lighthouse Point
Avoiding thin feathered crown edges
A crown that thins to a knife edge at the perimeter is fragile. Brick industry guidance says feathering the edge should be avoided, because the thin section deteriorates faster. That is often where the first pieces break away.
When we form a new crown, the edge keeps real thickness and projects past the brick. If your current crown has a feathered edge that has started to crumble, coating it will not add the missing body. We explain whether the edge can be kept or the crown replaced.
Staining on the brick below the crown
Streaks that run down from the top of the chimney show where water has been leaving the crown. A crown with no overhang or a failed drip lets water flow over the brick face instead of dropping clear. The stains are a record of that path.
We read the stain pattern together with the crown's shape. Streaks under one corner may point to a local break. Streaks all around the top can mean the crown sheds water badly by design. The repair differs in each case, and we explain which one we see.
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.
When crown sealing is the wrong recommendation
Sealing is a smaller job than replacement, so it is tempting to hear that a crown only needs a coat. On the wrong crown, that answer buys a short delay and another repair later. The coating will not hold loose concrete in place.
We recommend sealing only when the crown meets the conditions the product requires. When it does not, we say so plainly and explain what replacement involves. You make the decision, but you make it with an accurate picture of the top of your chimney.

Questions to ask before crown repair
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.
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.
Will crown work damage my roof covering?
The roof is protected where we stand, stage material and apply products. Spills are cleaned as the work proceeds. Tell us about fragile roofing before the visit so the access plan accounts for it.
