Chimney Crown Corbelling to Shed Water Effectively

Chimney Crown Corbelling refers to the decorative and structural brickwork beneath the chimney crown, where the chimney narrows or steps inward as it rises. Corbels are often used for architectural appeal or to provide additional support for the crown pad. Over time, these corbels can become a major point of water penetration, leading to damage to the masonry and the chimney structure.

At Nexus Chimney Services, we specialize in repairing and restoring chimney crown corbelling to ensure your chimney is protected from water damage while maintaining its structural integrity and aesthetic appeal.

Why is Chimney Crown Corbelling Important?

1. Water Protection

The corbels of a chimney create ledges that can collect water, snow, and debris. Without proper sealing, these areas allow water to seep into the masonry, leading to spalling, cracking, and other damage.

2. Structural Support

Corbels often support the chimney crown. When they are damaged or deteriorated, the crown’s stability is compromised, increasing the risk of failure.

3. Aesthetic Appeal

Corbelling adds a decorative touch to the chimney. Restoring or repairing damaged corbels helps maintain the chimney’s visual appeal and enhances the overall appearance of your home.

Signs Your Chimney Crown Corbelling Needs Repair

  • Visible cracks, gaps, or missing mortar in the corbel joints.
  • Spalling or crumbling bricks on the corbelling.
  • Water stains or efflorescence (white mineral deposits) on the chimney.
  • Loose or shifting bricks in the corbel area.
  • Leaks or water damage near the chimney structure.

Our Chimney Crown Corbelling Repair Process

1. Inspection and Assessment

Our certified technicians inspect the chimney to assess the condition of the corbels, crown pad, and surrounding masonry. This ensures we identify all areas needing repair and restoration.

2. Cleaning and Preparation

  • Loose or deteriorated mortar is removed from the corbel joints.
  • The surface is cleaned to eliminate dirt, debris, and old sealants, ensuring proper adhesion for new materials.

3. Mortar Application and Joint Repair

  • Fresh, weather-resistant mortar is applied to seal the joints between bricks, restoring strength and stability.
  • Mortar is color-matched to the existing masonry for a seamless appearance.

4. Sealing and Parging

  • A smooth layer of mortar is applied at a 45-degree angle to shed water efficiently from the corbel surfaces.
  • This parging layer prevents water from pooling or penetrating the brickwork.

5. Final Waterproofing

The repaired corbels and crown are treated with a commercial-grade waterproofing solution to protect the masonry from future water damage.
