How a chimney crown gets fixed properly
Casting a new crown on the chimney
A cast-in-place crown is built right on top of your chimney. Our crew removes the failed top, builds forms around the chimney, sets reinforcement and places the concrete with a slope running away from the flue. The forms create the overhang and the drip on the underside of the edge.
In section R1003.9.1, the Florida Building Code, Residential, calls for a masonry chimney cap made of concrete, metal or stone, pitched to throw off water, with a drip edge and a caulked bond break at every flue liner. We build to that description and walk you through each detail when the forms come off.
A cast crown also lets us correct what the old one got wrong. If the flue tile was buried, the new crown sits lower around it. If water ran down the face, the new overhang and drip send it clear. Tell us what bothered you about the old crown and we build the answer into the new one.
The bond break at the flue tile
The flue liner and the crown move differently. The liner heats and grows when the fireplace runs, while the crown around it stays cooler. If the crown is poured tight against the liner, that movement cracks the crown outward from the flue.
Section R1003.9.1 of the Florida Building Code, Residential, wants a caulked bond break at the flue liners, done to ASTM C1283. Our crew keeps a new crown separate from the liner and finishes the joint with a flexible sealant, so the two parts can move without breaking each other.
A clean joint at the flue also makes later work easier. When the liner or cap needs attention down the road, the break lets the crown stay in place. A crown cast tight against the tile often has to be broken out just to reach the liner.
Moss and debris on the crown
A crown with moss, leaves or dark growth on it stays damp longer after every rain. The growth holds water against the concrete and hides cracks underneath it.
Our crew clears the surface before inspecting, so we see the real condition. If the crown underneath is sound, cleaning it and correcting the drainage or adding a coating may be all it needs.
Growth on the crown also keeps the top damp, which wears out any coating sooner. After cleaning, our technicians look at why it was growing, whether shade, debris or a low spot, and address the cause when it is part of the crown repair.
Crown repair on chimneys with layers of old fixes
Older chimneys often carry several rounds of crown repairs, a mortar wash, a patch, a coat of tar and a coating on top. Each layer hides the one below it.
Our crew removes what is loose and looks at what is underneath before recommending anything. The written estimate explains what we found at each layer and which of those old fixes can stay.
Layered repairs also add bulk to the chimney top. Removing them lets the new crown sit at the right height around the flue tile. Our crew takes the layers off carefully so the brick underneath is left unharmed.

Crown repair questions we hear often
How can you tell a crown leak from a flashing leak?
Water from a cracked crown tends to show up inside the flue or the firebox, while flashing leaks usually stain the ceiling or wall beside the chimney. Both can happen at once. Our technician checks the crown, the cap, the flashing and the brick during the free inspection and tells you which one is letting water in.
