The brick under the crown

Months of water through a failed crown leave damage in the brick right under it. The top courses stay wettest, so their joints wash out and their faces flake first. Casting a new crown on top of loose or soft brick gives the new concrete a bad base.

Once the old crown is off, the top courses of your Fleming Island chimney are checked by hand. Loose brick is relaid and open joints repointed before the forms go up, and that masonry work is priced separately with the reason beside it. Cracks on top of the chimney in Fleming Island? Our masons tell you coat or recast after one look, so call (904) 920-5495.

Fleming Island falls within Clay County. In the 2020 Census, Fleming Island counted 29,142 residents.

How crown repair runs

Crack map from the roof
We identify the type of top and sketch each crack with its width, so the choice between coating and recasting is based on what is there.
Prep for coating or removal
A sound crown is cleaned and its wider cracks filled; a failed one is broken out down to sound brick.
Coat, or form and pour
The coating is brushed on in dry weather, or new concrete goes into forms with an overhang, a drip groove and reinforcement.
Cure, seal and refit the cap
The bond break at each flue is sealed, the concrete cures under cover, and the cap goes back on.

Standing water on flat crowns in Fleming Island

A crown with no slope holds a puddle after every rain, and the concrete under it stays wet for days. That water carries grit into the cracks and keeps them growing as the slab heats and cools.

New crowns in Fleming Island are sloped from the flue to the edge so rain leaves within minutes.

A crown coating costs less than a new cast crown, and both come 10% off.

Mapping the cracks before choosing a repair

Before we propose anything, the cracks on a crown are mapped: where each one starts, where it runs, and how wide it is along its length. A sketch shows them. The pattern matters as much for the diagnosis as the width does.

Cracks radiating from the flue corners point to the tile pushing on the crown. A crack running parallel to an edge, a short way in, points to a feathered edge breaking off. A web of fine cracks across the whole surface points to shrinkage in the original pour. Each pattern leads to a different repair, which is why the map comes first.

Filling larger cracks before the coating

A brushed crown coating bridges fine cracks, but it is not meant to fill wide ones. The data sheets for these products say larger cracks and voids are filled first, with a fast-setting patching cement or a suitable caulk, and the coating goes over the top.

We clean out each open crack, fill it flush, and let the fill set before coating. Skipping that step leaves a thin film stretched over a gap, which splits the first time the crown moves. The filled cracks are marked on the crack map so they can be checked at the next yearly visit.

Building the forms for a cast crown

A cast crown is shaped by its forms. Boards or form material are fixed around the top of the chimney, set out past each face by the planned overhang and level all the way round. A strip fixed to the underside of the form creates the drip groove.

Inside the forms, the top surface is shaped to slope from the flue tiles down to the edge on every side. The forms stay on until the concrete can hold its shape, and they come off without breaking the edge. The forms decide whether the finished crown sheds water or sits up there as a lump of concrete.

Before your crown is coated or recast

Does crown work mean the chimney cap comes off?

For a recast, yes. For a coating, it depends on how the cap is mounted. The estimate says which applies to your chimney.

Will a new crown fix my leak?

It fixes a leak that is coming through the crown. If the water is entering at the flashing, the brick or the flue top, a new crown will not stop it, which is why we trace the entry point first.
