Cracked chimney crowns from freeze-thaw cycles
Why it happens here
East Freehold gets repeated freeze-thaw cycles from late fall through early spring. Water seeps into small cracks in the crown, freezes, and expands. After a few winters, a hairline crack becomes a major leak. This is the most common cause of chimney leaks we see in 07728.
Our approach
We pour new crowns with chimney crown mix that flexes with temperature changes, then coat the stack with ChimneySaver water repellent. That combination keeps water out and prevents future cracking. Most crown repairs take three to five hours and come with a 5-year warranty.
