Chimney Crown Repair or Rebuild in Evesham, NJ
Evesham's housing is almost entirely post-1950, with a median build year of 1986. A crown that has cracked after thirty-odd years is repaired or rebuilt, depending on how far it has gone.
Evesham, in Burlington County, is about 54% detached houses and 72% owner-occupied. The median build year is 1986, only about 2% of homes predate 1950, and the ACS median home value is about $398,000.
Chimneys in houses of that age are old enough for the crown to have cracked and young enough that no one has looked.
This page walks through the repair-or-rebuild decision.

Repair or rebuild a crown
| Condition | Typical response |
|---|---|
| Hairline cracks, firm surface | Seal with a flexible crown coat |
| Open cracks, intact slope | Patch and coat |
| Crumbling or sunken areas | Rebuild |
| Separated from the chimney | Rebuild |
| Never properly formed | Rebuild |
A coating on a crown that is failing underneath hides the problem. Rebuilding means removing the old crown and casting a new one with a proper slope. Done well, it lasts. See crown repair and cracked chimney crowns. Our crown work includes Delran and Mount Holly.
Aftercare
Keeping a repaired crown from cracking again
A crown fails again when the cause is left in place. Water standing on the crown, a missing cap that lets the flue wet the crown from inside, and movement between the flue tile and the crown are common causes. A good repair addresses the slope, the seal around the flue and the cap together.
After a repair, look at the crown once a year from the ground or by photo. New cracks in the first few years suggest the cause was not addressed.
Housing profile
What the housing mix means in Evesham
About half the housing here is attached, so a first question can be whose chimney it is. In a detached house built in the 1980s, the practical checks are the crown, cap and flashing. In a townhouse, find out who maintains the stack before you book anything.
