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 St. Nicholas 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 St. Nicholas street, and we will book a dry-weather visit to the crown.

St. Nicholas sits in Duval County. The coast is more than about six miles from St. Nicholas.

How It Works

From crack map to cured crown in St. Nicholas

Crown checked from the roof
We look at the slab, the brick right under it and the seal around each flue, then write down the option that fits with its price.
Old top cleaned or torn off
For a coating, the crown is cleaned and the wider cracks filled. For a recast, the old top comes off down to sound brick.
Coating brushed on or crown poured
A coating goes on in dry weather inside the maker's temperature range. A recast is formed with a slope, an overhang, a drip groove and a sealed joint at every flue.
Curing, then the cap goes back
New concrete stays covered and damp while it cures. The cap is refastened once the crown can hold it, and we show you the finished top.

Local Conditions

Standing water on flat crowns in St. Nicholas

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 St. Nicholas are sloped from the flue to the edge so rain leaves within minutes.

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.

Reinforcement inside a cast crown

Concrete shrinks as it cures and moves with heat afterward, and without reinforcement those movements open cracks. BIA Technical Note 19B calls for adequate reinforcement in a cast cap to control cracking from shrinkage and thermal movement, with extra where the cap overhangs the face.

The reinforcement is placed within the thickness of the crown, clear of the brick below and the surface above, so concrete surrounds it on all sides. Where a crown will stay wet for long spells, the type of reinforcement is chosen with corrosion in mind. You are told what goes in before the pour.

Moss, leaves and standing water on a crown

Debris or moss on a crown keeps it wet longer after every rain. Leaves trapped against the flue tile, grit from a failing cap, or a green film growing in the low spots all hold water on the surface and feed it into any crack.

Clearing the crown is part of every visit to the top. Growth that keeps coming back points to a crown that holds water, from a flat surface or low spots near the tile, and that is a reason for reshaping or recasting rather than simply cleaning again. Growth is scraped off by hand, without a pressure washer.

FAQ

Crown repair questions from St. Nicholas

Can a crown be repaired in the rain?

No. Coatings and fresh concrete both need dry conditions for a set time after they go on. Crown work is scheduled for dry weather, and rain protection is on hand in case a shower arrives early.

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.
