What to Do About a Cracked Grove City Chimney Crown
A cracked crown is cheap to seal and expensive to ignore. The honest guide for Grove City owners.
Because you cannot see it from the ground, the crown is the most overlooked part of a Grove City chimney. The crown is the top concrete slab, shaped to shed water past the flue tiles. Failure sends water into the masonry, and the first sign is usually an interior stain.
The job the crown is built for
Done right, the crown is essentially a concrete roof for the chimney top. It is sloped to shed water off the tiles and overhangs the brick with a drip edge so water falls away from the stack. A poor crown — and Grove City has plenty — is thin, mortar-not-concrete, flush to the face, and cracked.
A poor crown — and Grove City has plenty — is thin, mortar-not-concrete, flush to the face, and cracked. Picture the crown as a tiny concrete roof over the brickwork. Sloped to drain and overhanging the brick, a good crown sends water away from the masonry.
It tilts water away from the tiles and extends past the brick face to carry runoff clear. Bad crowns, which we see often in Grove City, are thin, flush, and made of mortar rather than concrete. The crown is, in effect, the chimney's own concrete roof.
The case for sealing
A fundamentally good crown with hairline cracks should be sealed, not torn off. A flexible brush-on coating bridges the cracks and flexes with the masonry through the seasons. On a sound crown, the coating adds years of service at a fraction of the rebuild cost.
On the proper crown, a seal adds substantial life for a small share of a rebuild's cost. A sound crown with minor cracking is exactly when sealing is correct. The flexible coating bridges the cracks and accommodates seasonal expansion and contraction.

- Hairline cracks on an otherwise solid, well-shaped crown
- No missing chunks or crumbling sections
- The overhang and drip edge are intact
- The flue tiles are still well-supported by the crown
The rebuild-it situation
Sealing a crown that has failed structurally is money down the drain. A crown that is crumbling, missing chunks, cracked all the way through, or built without an overhang has to be rebuilt. We form a new crown with the slope and overhang the original missed, in proper concrete.
A proper rebuild gives the crown the shape and materials it should have had. A coat on a crumbling crown is lipstick on a failure. A crown that is crumbling, missing chunks, cracked all the way through, or built without an overhang has to be rebuilt.
If the crown is gone structurally or was never built right, it comes off and gets rebuilt. We form a new crown with the slope and overhang the original missed, in proper concrete. A coat on a crumbling crown is lipstick on a failure.
Where integrity shows on a crown job
Nowhere is honesty more visible than in the seal-versus-rebuild call. The bad actors rebuild every crown they see, because rebuilds pay more. We are happy to talk you out of work your chimney does not need.
Our process for sizing up a crown
We get on the roof, read the crown, and photograph it so the call is provable. We point to the cracks and the overhang and the condition, then explain the right move. From there the call is yours to make, fully informed.
