Pieces of crown on the roof
Chunks of gray concrete or mortar on the roof, in the gutter or on the ground below the chimney most likely came from the top of the stack. Their shape tells us something: thin, feathered flakes point to a mortar wash breaking up at its edges, while thicker blocks suggest a cast crown cracking through.
If you find pieces around your Keystone Heights house, keep one to show us, stay off the roof, and keep people clear of the area below the chimney. Loose pieces still on the crown can fall in the next wind, and removing them safely is part of the first visit. Cracks on top of your Keystone Heights chimney?

How It Works
From crack map to cured crown in Keystone Heights
-
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
Crowns around two or more flues in Keystone Heights
A crown over several flues has to drain between the tiles as well as off the outside edges. A flat patch between two tiles holds water against both.
Recasts in Keystone Heights are sloped away from every tile, and each tile gets its own sealed bond break.

Taping the flue tile before a coating
Before a crown is coated, tape goes around each flue tile, set a little higher than the crown surface. The coating is brushed up to that line, over the tile-to-crown joint, and ends in a clean edge instead of a ragged smear.
What sits in the joint where the tile meets the crown matters more than the tape. The bond break the code asks for is a flexible, caulked joint that lets the tile expand as it heats while the concrete stays put. Rigid patching cement packed into it locks the tile to the crown, and the next fire cracks one or the other. An open joint at the tile is cleaned out and resealed with a flexible sealant before the coating goes on.
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.
Keeping new concrete damp while it cures
Concrete gains strength through a chemical reaction that needs water, and a crown on a sunny, breezy roof dries out fast. If the surface dries too early, it can craze and dust, and the crown ends up weaker than its mix should give.
After the pour, the crown is covered and kept damp for the curing period the mix calls for, and it is protected from rain until it has set. The forms come off once the concrete can hold its edges. Those steps are why a crown recast can take more than one visit, and you know in advance when each one happens.

FAQ
Crown repair questions from Keystone Heights
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.
