Crowns on gas-vented chimneys

A masonry chimney that vents a gas appliance still has a crown taking rain, and it cracks for the same reasons. Where the flue has been relined with a metal liner, the liner's top plate sits on the crown and has to be sealed to it, so the crown and the plate work together.

Crown repair on a relined Kings Ferry chimney accounts for the liner: the top plate comes off and goes back, and the seal between them is renewed. The appliance itself is not part of crown work, and the two are kept apart. We check the cap and flashing on the same free trip to your Kings Ferry crown; call (904) 920-5495.

The county for Kings Ferry is Nassau County. Kings Ferry is inland.

Map, prep, coat or pour, cure

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.

Coating a sound crown in Kings Ferry

Many cracked crowns in Kings Ferry are still solid underneath. When the slab does not move under pressure and the cracks are hairline, a flexible crown coating is the right repair and the smaller bill.

We fill the wider cracks first, tape the flue tiles and brush the coating on in a dry spell.

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

Hairline, open and through cracks

Crown cracks come in three broad kinds. Hairline cracks are surface lines you can see but not fit a fingernail into. Open cracks have width and depth, and water pools in them. Through cracks run the full thickness of the slab, so a piece moves when pressed or water drains straight into the chimney.

Hairline cracks on a sound crown are the case for a coating. Open cracks need filling first, and a coating after. Through cracks, especially several of them, mean the crown has become separate pieces, and the reliable repair is a new crown. The crack map records which kind each crack is.

Giving a crown enough slope

Slope is what makes a crown shed water, which is why the residential code's crown section asks for it, and a flat top defeats that purpose. Water that sits on it soaks into the concrete, finds every hairline crack, and carries dirt and dissolved salts into the pores.

The slope runs from the flue tiles down to the outer edge on every side, steep enough that water moves off promptly without pooling at the tile. Where two or more flues share the crown, the surface between them slopes away as well, so no low spot is left to hold water. The slope is checked with a level before the concrete sets.

What the yearly check looks for on a crown

Under NFPA 211, a chimney gets a yearly soundness check, and the crown is one of the parts that check looks at closely. We note new cracks, cracks that have widened since last time, the state of the bond break at each tile, and the condition of any coating.

A crown caught with a few new hairline cracks can be coated in an afternoon. The same crown left for several years can need recasting and new brick under it. The yearly record, with the crack map from the last visit, is what makes that comparison possible. We keep that map on file for the next visit.

Coat or recast, and the reasons

Top courses of brick relaid before the new crown goes on
Flue tile height above the finished crown
Chimney cap removal and reinstallation, with how it is fastened
Cure time before the cap goes back and the fireplace is used

Crown repair questions from Kings Ferry

Can I tell from the ground whether my crown is a mortar wash?

Sometimes. A thin gray layer that tapers to the edge with no overhang is likely a wash, while a thicker slab that projects past the brick is likely a cast crown. We confirm it from the roof.

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.
