Chimney Crown Repair | CrownSeal

Chimney crowns are concrete structures at the top of masonry chimneys that guard the inside of the chimney and help to protect the bricks below the crown from water. A damaged chimney crown can lead to very serious problems if not repaired, costing you more money in the long run.

Crown Repair Rockaway, NJHow Chimney Crowns Get Damaged

While concrete is strong, there are a variety of events that can cause it to crack such as:

  • Lightning strikes
  • Incessant pounding hail
  • Season after season of extreme temperatures
  • Earthquakes
  • Plain old age

What Happens When a Crown Is Cracked

A cracked chimney crown will allow rain and melting snow to run into the interior areas of the chimney. When this happens, both the chimney masonry and adjacent building materials of the home can be affected by theschimney leaks.

Another concern with water moving into dark, out-of-the-way places is mold growth. Mold thrives in unventilated areas that remain cool and damp for extended periods. Some mold is harmless. Other kinds are potentially hazardous. You don’t want any of it in or near your home.

When a chimney crown is decayed or broken, water also can seep down into the topmost bricks of the chimney just beneath the crown. Bricks are much more susceptible to water damage than concrete, so this is a scenario you want to avoid with a chimney crown repair.
