Chimney Crown Repair & Rebuilding

The concrete chimney crown at the top of your chimney has a very important purpose: it shields the interior spaces of the chimney from damaging water.

Is your chimney crown cracked, crumbling, or seriously deteriorated? The Chimney Guys can solve the problem quickly with expert chimney crown rebuilding or basic crown repair work.

What Causes the Need for Chimney Crown Repair?

Several things can cause or lead to crown damage, including:

  • Lightning
  • Hail
  • Freezing temperatures/Freeze/thaw cycles
  • Inferior concrete or cheap mortar used to build the crown
  • Poor workmanship
  • Old age

What’s a Crown Supposed to Look Like?

When built correctly, a chimney crown will be no less than two inches thick at its thinnest point. It will be slanted to force water to run off its edges, which should extend beyond the exterior walls of the chimney by at least two inches. It should have a uniform appearance, with the flue liner extending slightly above it.

Consequences of a Damaged Chimney Crown

Masonry damage: When a deteriorated crown leaves the bricks below it exposed to the elements, serious masonry problems are on the way.

Chimney liner damage: Water infiltrating the chimney can eventually damage the chimney liner and allow smoke, carbon monoxide, acidic compounds, and intense heat to escape.

House damage: Water damage is like a living thing – it spreads and grows. A major leak in a chimney crown can eventually result in water damage to walls, ceilings, flooring, the attic, and other parts of the home.

Mold growth: Mold thrives in dark, damp and poorly ventilated spaces. The interior of a chimney is the perfect place for a leak to cause an outbreak of potentially harmful mold.

Crown Repair and Rebuilding Strategies

After we evaluate the condition of a chimney crown, we have several strategies to solve the problem for our Columbus customers. Basic crown repair is the right choice for crowns with small cracks or minor deterioration. After the repairs are made, we’ll coat the crown with a special water repellant to keep it protected for years.
