Chimney crown repair and rebuilds in Rosemont North

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.

Crown repair and a new cap in one trip

When both the crown and the cap need work, doing them together saves a second trip up the roof. Crown work comes first, a repair or a full recast, and the cap is fastened on only when the new surface will hold its anchors.

We still price them as separate lines because they are separate parts. You can approve the crown now and the cap later, or both at once. When both are done together, our crew fits the cap and checks it before the ladder comes down.

Some caps cover several flues at once and rest on the crown itself. Those need a crown that is flat enough where the cap sits and sloped everywhere else. Our crew plans the crown with the cap in mind, so the two work together from day one.

What a full crown rebuild includes

A crown rebuild covers the whole top of the chimney. The old crown comes off, the top brick is checked, forms go up, reinforcement goes in, and a new sloped crown is cast with an overhang and drip.

After it cures, the flue joint gets its sealant and any cap is refitted. Our written estimate lists each of those steps, and at the end of the job we walk you through them so you know exactly what you paid for.

A rebuild also includes protecting the flue during the work and checking it afterward, so no debris is left inside. If the cap needs replacing, it is fitted once the crown has cured. Everything is listed, so you can see what the rebuild includes and what it leaves out.

• Old crown removed down to sound masonry
• Forms, reinforcement and a sloped pour
• Bond break and sealant at each flue
