Chimney crown replacement and repair across Imperial Point

Crown cracks that start at a flue tile

A pattern of cracks spreading out from one flue tile is a useful clue. The crown may have been cast tight against the liner, with repeated heating pushing it apart. Water then follows the same lines into the chimney.

Filling those cracks without freeing the liner joint may not stop them returning. We check whether the crown can be cut back and resealed at the liner or whether it has broken up too far. Either way, you see the cause explained, not just the crack.

Crown repair from a family-owned local team

Miami Chimney Repair is a family-owned, locally owned company. We explain crown findings ourselves and answer questions about the work directly. You do not have to relay questions through a chain of people to understand your chimney top.

That matters for crown repair because so much depends on judgment at the top of the chimney. We explain what we saw, why we chose a method and what it leaves out. Upfront pricing and no hidden fees mean the price you approve covers the agreed scope.

Conditions that decide sealing or replacement

The choice between coating and a new crown comes down to a few conditions. We check each one on your chimney and explain what we found.

When all of these hold, a coating may be a sensible repair. When one or more fails, a coating would cover a problem it cannot solve, and we explain replacement instead.

• The concrete is firm and still attached to the brick
• The crown slopes away from every flue
• The edges keep real thickness and overhang the face
• The joint at each flue can be resealed

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.
