cracked chimney crown in Simsbury CTWhat is a Chimney Crown?

The chimney crown is the concrete slab around the flue opening at the top of a chimney. This component is crucial as it safeguards the flue liner and masonry walls against harsh weather conditions such as rain, snow, and ice. Additionally, the chimney crown hangs over the edge like an umbrella that acts as a barrier to prevent water intrusion that can cause extensive damage to the masonry.

Common Causes of a Cracked Chimney Crown in Central CT

Some of the most common causes contributing to a cracked chimney crown include:

Age: Chimney crowns have a lifespan of around 20-30 years, but they can start to crack and deteriorate much sooner when damaged or improperly maintained.

Weather: Exposure to extreme weather conditions, such as high winds, frequent rain, snow accumulation, ice, and even lightning, can damage the chimney crown.

Trees: Gusty winds and root damage can weaken trees, causing them to fall and damage your chimney's crown.

Poor construction: If the chimney crown is not constructed correctly, it is more likely to crack.

Dangers for Connecticut Homeowners

When a chimney crown cracks, it can pose many dangers to Connecticut homeowners, including:

Water damage: Water that seeps into the chimney system can damage the bricks, mortar, and flue liner. Thus leading to costly repairs and even structural problems.

Mold growth: Moisture in the chimney can also lead to mold growth. Mold can cause various health problems, including allergies and respiratory infections.

Carbon monoxide poisoning: A cracked chimney crown can let carbon monoxide gas escape into the home. Carbon monoxide is a colorless, odorless gas that can be fatal.

Chimney fires: Creosote, a byproduct of wood combustion, can build up in the chimney and cause a fire. A cracked chimney crown can make it more difficult for creosote to escape, increasing the risk of a chimney fire.
