The exterior of a chimney is very susceptible to water damage because of a variety of factors. A common issue is not having a properly built cricket on your chimney to direct water-flow down and off the roof. Without a proper cricket, water build up can occur, creating leaks and wood rot.
Chimneys require special attention and maintenance to prevent costly property damage caused by water penetration. If a chimney is neglected for an extended period of time, the system becomes compromised and can create mold or make the fireplace unsafe to use entirely.
