The crown adorns the uppermost portion of the chimney, deflecting rain, snow, and debris away from the chimney flue like a royal guard. However, this porous structure, typically constructed with leftover mortar or concrete, is susceptible to damage due to weather, settling, or foundation issues and may need repair or rebuilding to prevent water damage to the interior masonry and components. Horizon’s skilled masons are specialists in repairing and rebuilding chimney crowns in eastern MA and RI.
Chimney Crown Repair
Sealing the cracks with an elastomeric, water-resistant coating is a viable option for crowns with minor damage. It is cost-effective for addressing minor surface damage and extending the crown's life.
Chimney Crown Rebuilding
Complete or partial rebuilding may be necessary when the chimney crown has severe damage, such as missing pieces or large surface gaps. After removing the affected section or entire crown, our masons rebuild a new crown to code. A properly constructed crown will overhang three inches and have a drip edge to direct precipitation away from the chimney. A waterproof coating is applied to protect the crown from future water damage. Crown rebuilding is a long-term solution ensuring the chimney structure's structural integrity.
What Happens When Chimney Crowns Are Damaged?
When the chimney crown has cracks or other damage, water penetrates inside the flue. It can lead to a host of problems, including:
- Damaged Flue Liner: Water can weaken or crack the flue liner, compromising its ability to vent smoke and gases properly.
- Deteriorating Masonry: Freeze-thaw cycles can cause the mortar joints in the chimney to crack and crumble, leading to structural instability.
- Water Damage: Leaks in the crown may damage not only the chimney but also your attic and roof deck.
- Chimney Draft Problems: A damaged crown can disrupt the airflow in the chimney, making it difficult to start or maintain a fire.
Signs of Chimney Crown Damage
- Visible Cracks: Cracks in the crown, regardless of size, indicate potential problems.
- Mortar Decay: Mortar pieces falling onto the roof or into the firebox indicate deterioration.
- Water Leaks: Dampness or water stains around the chimney or on the ceiling below.
- Flue Liner Damage: While not always visible, a damaged flue liner can indicate crown issues.
