Chimney Poured Crowns

A professionally installed poured concrete crown from Chimney Concepts typically lasts 20-30 years or more. The longevity depends on factors such as local climate conditions, the quality of materials used, proper installation techniques, and regular maintenance. Our crowns are constructed with high-quality concrete mixes and proper reinforcement to maximize durability.

A chimney crown is the concrete structure that covers the top of the chimney masonry, while a chimney cap is a metal cover that fits over the flue opening. The crown seals the top of the brick structure and directs water away from the chimney, while the cap prevents rain, animals, and debris from entering the flue. Both components are essential for a properly functioning chimney system.

Minor cracks and damage to a chimney crown can often be repaired using specialized crown sealing products. However, if the crown has significant structural damage, improper construction (too thin, flat, or lacking an overhang), or has deteriorated substantially, a complete replacement is usually the better long-term solution. Our technicians can assess your crown's condition and recommend the most appropriate approach.

A poured concrete crown is a properly constructed, reinforced concrete structure with the correct thickness, slope, and overhang. A mortar wash (sometimes called a mortar crown) is simply a thin layer of mortar spread over the top of the chimney. Mortar washes crack easily, don't provide adequate water protection, and typically fail within a few years. Poured crowns offer superior protection and longevity.

The installation of a new poured concrete crown typically takes one day to complete. This includes removing the old crown, preparing the surface, building forms, pouring the concrete, and finishing the crown with the proper slope and drip edge. The concrete will need time to cure properly before exposure to rain or extreme temperatures, which our technicians will account for in the scheduling process.
