How to Install a Chimney Crown

Installing a chimney crown is an important task that helps protect your chimney from water damage and other potential problems. Here are the steps to follow for a successful installation:

Step 1: Clean the Chimney
Before installing a chimney crown, you need to make sure the chimney is clean. Remove any debris or loose mortar from the top of the chimney with a wire brush or scraper. This will ensure that the crown will sit flat on the chimney and create a proper seal.

Step 2: Measure the Chimney
Measure the dimensions of the chimney to determine the size of the crown you need to install. The crown should extend at least 2 inches beyond the edge of the chimney on all sides.

Step 3: Mix the Mortar
Mix the mortar according to the manufacturer's instructions. You want the mortar to be thick enough to hold its shape, but not so thick that it's difficult to work with.

Step 4: Apply the Mortar
Apply a layer of mortar to the top of the chimney, making sure to cover the entire surface. Use a trowel to smooth the mortar and create a flat surface.

Step 5: Install the Crown
Carefully place the crown on top of the chimney, making sure it's centered and level. Press down on the crown to ensure it's firmly seated in the mortar.

Step 6: Smooth the Crown
Use a trowel to smooth the edges of the crown and create a slope that will allow water to run off. Make sure the slope is even on all sides.

Step 7: Let the Mortar Dry
Allow the mortar to dry completely before using the chimney. This can take several days, depending on the temperature and humidity.

Step 8: Seal the Crown
Once the mortar is dry, apply a coat of chimney crown sealer to protect the crown from water damage and other potential problems.

By following these steps, you can install a chimney crown that will provide long-lasting protection for your chimney. Remember to always wear protective gear, such as gloves and eye goggles, when working with mortar.
