When the crown is breaking up

When pieces of the crown lift out by hand, cracks run clear through the slab, or the edges have crumbled back from the brick, a coating has nothing sound to hold. The crown has to come off.

At that stage, the old top on the Lakeside chimney comes off until firm brick shows, water-damaged courses are relaid, and a new crown is cast with slope, an overhang, a drip groove underneath and a bond break at the flue. Each of those steps carries its own price. Nothing is poured until the base below is firm and level. Call (904) 920-5495 with your Lakeside street, and we will book a dry-weather visit to the crown.

Lakeside is in Clay County. Lakeside had 31,275 residents at the 2020 Census.

How our crown specialists repair a crown in Lakeside

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.

Flue heat and crown cracks in Lakeside

When a fire burns, the flue tile warms and grows, and a crown poured tight against it cracks outward from the tile corners. That pattern shows up on chimneys everywhere, including in Lakeside.

Our recasts leave a flexible bond break around each tile, sealed to the ASTM C1283 practice the code names, so the tile can move without splitting the crown.

Weather windows for a crown coating

A crown coating is only as good as the day it goes on. The coating maker's data sheet sets the rules: a surface and air temperature range, a clean and dry surface, and no rain due before the coating has had time to set, unless the crown can be protected.

That means crown coatings are scheduled for dry spells, and a day that looked fine can be called off if showers move in. We also cool a sun-heated crown with a light mist where the data sheet allows it, since a hot surface can make the coating skin over too fast.

What goes into the bond break at the flue

The bond break is the flexible joint between the crown and each flue tile. It lets the tile grow with heat without pushing on the concrete. The code calls for it to be caulked, following ASTM C1283, and the BIA detail shows a backer rod with sealant over it.

In practice we wrap the tile with a compressible material before the concrete is placed, then rake the top back and fill it with a primed backer and a sealant suited to heat and weather. The finished joint stays flexible. A crown poured tight against the tile, with no gap at all, is the fault this detail exists to prevent.

Crowns around more than one flue

When a chimney has two or more flues, the crown has to drain between them as well as off the outside edges. The space between flue tiles is a natural low point, and a flat area there will hold water against both tiles.

Each tile needs its own bond break and its own check for height and cracks. Where the tiles are close together, forming the crown between them takes care so the concrete fills fully without voids. A cap that covers several flues sits on the finished crown, and its fastening is planned before the pour. Each flue's findings are recorded separately.

Before your crown is coated or recast

When does a crown coating need to be redone?

The coating maker's data sheet gives the guidance, and the yearly check tells us in practice. A coating that has stayed flexible and firmly attached can be left; one that has cracked or peeled is cleaned off and renewed.

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.
