Chimney Crown Repair Beachwood, NJ
Cracked chimney crowns in Beachwood can usually be sealed if caught early, or replaced if the concrete is crumbling, so rain stops soaking into the brick from above. Dial (732) 966-9204 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. Because it faces every storm, freeze and heat wave head on, the crown is usually the first part of the chimney to fail. Once it cracks, water runs straight into the brick and mortar below, and every freeze widens the crack.
It helps to separate the crown from the cap. A cap is metal and covers the flue opening, while the crown is concrete and covers the rest of the chimney top. One cannot stand in for the other.
Crowns often fail sooner than they should for a few common reasons. A common shortcut is a thin layer of mortar troweled over the top, with no overhang to throw water clear and nothing to let the flue tile expand. That combination tends to crack within a few winters.
Many chimney crown repair calls in Beachwood also turn up a need for chimney cap installation or chimney leak repair.

Call nowThe process
What happens during a crown repair
The right fix depends on whether the crown is basically sound with surface cracks or failing all the way through.
Assess the cracks
The technician checks the crown for crack size and depth, overhang, slope and the joint around the flue tile. The cap and the upper masonry are part of the same check.
Prep the crown
The crown is scrubbed of dirt, growth and loose pieces so repair material can grip. Good prep decides how long the repair lasts.
Coat the crown
For minor cracking, a brushable crown repair coating seals the cracks and stretches with the concrete as it moves. This is a good option when the crown is solid and the cracks are caught early.
Replace the crown
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.
Expansion joint
The gap around the flue tile is filled with a flexible sealant rather than locked tight in concrete. Without it, the hot flue tile will crack a new crown just like the old one.
Cap the flue
With the crown done, a cap with a mesh screen is added to keep rain and animals out of the flue. Any spalled brick at the top can be repaired at the same time.
What is included
Crown work a chimney sweep handles
Crack sealing
Hairline cracks are sealed with a flexible crown coating to extend the life of the crown.
Upper brick repair
Damage to the top courses from a leaking crown is fixed in the same job before the crown goes on.
Expansion joints
The joint between the crown and flue tile is opened and sealed with flexible material so heat does not crack the crown.
Drip edges
The crown extends past the chimney face which keeps runoff from soaking the masonry.

Chimney Crown Replacement Beachwood, NJ
When a crown has deep cracks, loose chunks or no overhang at all, replacing it is more reliable than sealing it. The old crown is broken out down to the brick, and the top courses are checked and repaired if needed. A form is built around the top of the chimney, a bond break goes around the flue tile, and the new crown is cast with a slope, an overhang and a drip edge.
Crown work in Beachwood depends on the season. Fresh concrete should not freeze while it cures, which makes mild weather the best time for the job. In the meantime, a temporary cover can keep the worst of the water out. Ask the chimney sweep whether the new crown will have an overhang, a drip edge and an expansion joint at the flue, since those three details decide how long it lasts.

Chimneys in this climate
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. 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, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Beachwood, NJ schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Crown Repair questions
When does a chimney crown need replacing?
A properly built concrete crown with an overhang and expansion joint can last for decades. The weak ones are thin, flush with the brick and cast tight to the flue. An annual inspection catches cracks while they can still be sealed.
What causes chimney crowns to crack?
Crowns crack from water freezing in small cracks, from being built thin out of mortar, and from the flue tile expanding against them. A crown cast tight against the flue tile will crack when the tile heats and expands. Water and frost then finish the job.
Can a cracked chimney crown be repaired?
That depends on how deep and widespread the cracks are. Hairline cracks in a solid crown can be sealed with a flexible crown coating that bridges the cracks and keeps water out. If the crown is cracked through, crumbling or missing pieces, replacement is the better option.
What is the difference between a chimney crown and a chimney cap?
The crown is the concrete or mortar slab that covers the top of the masonry around the flue, and the cap is the metal cover that sits over the flue opening. The crown keeps water out of the brick, and the cap keeps rain, animals and debris out of the flue. A cap cannot make up for a cracked crown.
Is a cracked chimney crown a big deal?
Small crown cracks deserve attention because they let water straight into the chimney. Once water reaches the masonry, it leads to spalled brick, failing mortar, rusted dampers and damaged flue tiles. Sealing a crack early is a small job, while ignoring it can lead to rebuilding the top of the chimney.
