Bond breaks
The flue tile is separated from the crown so heat does not crack the crown.
A chimney sweep in Edgewater can seal hairline cracks in a chimney crown or rebuild a crown that is breaking apart, with a design that sheds water past the masonry. Dial (551) 378-0034 to talk with a local chimney sweep about the crown.
The chimney crown is the slab of concrete or mortar on top of the chimney, around the flue tile, and its job is to keep water out of the masonry below. Sitting fully exposed at the highest point of the house, it takes a beating from rain, snow and sun. A cracked crown funnels water into the chimney, where freezing and thawing break the masonry apart from the top down.
A crown is not the same as a chimney cap, though the words are often mixed up. The cap is a metal hood over the flue that keeps out rain and animals, and the crown is the concrete it is mounted on. One cannot stand in for the other.
Many crowns crack early because of how they were built. Many original crowns are thin mortar caps rather than proper concrete, with no drip edge and the flue tile locked tight in the mix. Mortar shrinks and cracks under weather, and an expanding flue tile will split a crown that has no room for movement.
Many chimney crown repair calls in Edgewater also turn up a need for chimney cap installation or chimney leak repair.

Call nowThe right fix depends on whether the crown is basically sound with surface cracks or failing all the way through.
From the roof, the crown is examined for cracks, crumbling, poor slope and missing overhang. Damage to the top courses of brick or the flue tile is noted too.
The crown is scrubbed of dirt, growth and loose pieces so repair material can grip. Good prep decides how long the repair lasts.
Hairline cracks in an otherwise sound crown are filled and the whole crown is coated with a flexible, elastomeric crown sealer. It is the least invasive fix when the crown is still intact.
If the crown is crumbling, thin or cracked through, it is removed and a new one is formed and cast. A proper replacement slopes away from the flue and extends past the brick with a drip edge underneath.
A bond break is left between the crown and the flue tile so the tile can expand without cracking the crown. That one detail prevents the most common crown cracks.
A chimney cap is installed or reset over the flue once the crown has cured. It is a good moment to repoint the top courses if needed.
The flue tile is separated from the crown so heat does not crack the crown.
A failed crown is replaced with a properly built concrete crown built to last through many winters.
Small cracks in a sound crown are sealed that keeps water out and moves with the concrete.
The crown extends past the chimney face so water drips clear instead of running down the brick.
The brick under the crown is repointed or replaced where needed to stop damage from spreading downward.
When a crown has deep cracks, loose chunks or no overhang at all, replacing it is more reliable than sealing it. First the failed crown comes off, exposing the top of the brick and the flue tile. Forms are set to create the overhang, the flue tile is wrapped to allow movement, and concrete is placed and sloped away from the flue.
For Edgewater homeowners, timing matters with crown replacement. Fresh concrete should not freeze while it cures, which makes mild weather the best time for the job. A winter crown failure can often be sealed temporarily to buy time until warmer weather. It is worth asking how the new crown will handle water runoff and flue tile expansion.
Around Edgewater, crown cracks usually show up after a winter of freezing and thawing. Across Edgewater and nearby places including Cliffside Park, Fairview, Fort Lee and Palisades Park, the crowns that crack first are the ones with no overhang and no room for the flue tile to move, which is why catching crown cracks in their first season keeps the repair simple.

Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Edgewater, NJ schedule a sweep in early fall, and a repair check after a hard winter.
Small chimney problems caught early usually stay small repairs.
Local sweeps see the same chimney types and weather wear across Edgewater and nearby towns.
Ask the sweep about the cause, the options and the estimate before work starts.
