The Cost and Process of Chimney Crown Replacement


Chimneys are essential to any home, providing ventilation for fireplaces and heating appliances. Over time, chimneys can develop damage and need repairs to continue functioning correctly. One common repair is chimney crown replacement.

This article will explore the cost and process of chimney crown replacement. You can make informed decisions for a sturdy, durable chimney by understanding the steps.

Process of Chimney Crown Replacement

The chimney crown is the topmost part of a chimney. It is often made of concrete or masonry. Over time, the chimney crown can crack or deteriorate due to exposure to weather and temperature changes. 

The process of replacing a chimney crown typically involves the following steps:


Before starting the replacement process, conducting a thorough inspection of the chimney crown is essential. This inspection will help determine the extent of damage and if any other repairs are needed. Hiring a professional chimney sweep or inspector for this task is recommended.

Removal of Old Crown

Once the inspection is complete, removing the old crown is next. This involves breaking and removing the existing crown, ensuring no debris falls into the chimney flue. It is crucial to take safety precautions during this step, such as wearing protective gear and using essential tools.

Preparation of New Crown

The new crown is typically made of concrete or masonry materials. It needs to be specifically designed to fit the dimensions of your chimney.

The chimney repair involves creating a mold or formwork for the new crown and allowing it to dry completely. This process can take a few days, depending on the materials used.

Installation of New Crown

The crown should be appropriately aligned and secured with mortar or appropriate bonding materials. Ensuring the new crown slightly slopes away from the chimney is crucial. Professional crown installation also involves reinforcing the edges of the crown with wire mesh.

Sealing and Finishing

After installation, the new crown needs to be sealed with a waterproofing agent to protect it from future damage. This step is essential for crown longevity and preventing water leaks. 

Cost of Chimney Crown Replacement

An average chimney crown repair can range from $500 to $1500. The cost of chimney crown replacement can vary depending on various factors. This includes:

Size and Height of the Chimney

Larger and taller chimneys require more materials, labor, and time to replace the crown. Therefore, they often have a higher cost.

Materials Used

The type of material used for the new crown can also affect the overall cost. Concrete crowns tend to be less expensive compared to masonry ones. However, masonry crowns are more durable and can last longer.

Additional Repairs Needed

During the inspection process, it is possible to discover other damages that may need to be repaired before replacing the crown. These repairs can add to the overall cost of chimney crown replacement.

Labor Cost

The labor cost associated with chimney crown replacement is a significant factor. This cost is influenced by the complexity of the job and the amount of time it takes. It’s always best to get multiple quotes from reputable professionals before deciding.

Having a Chimney Crown Replacement

Chimney crown replacement is a crucial maintenance task that ensures your chimney remains in good condition and prevents further damage to your home. Remember to consider all the factors mentioned above when estimating the cost of chimney crown replacements. So, please do not neglect your chimney and schedule regular inspections to catch any issues before they become significant problems.
