Chimney Crown Repairs

It’s a common thought that a “chimney” is one continuous structure, but a chimney is actually made up of several parts. At the top of the chimney, you have the crown and the chimney cap. There are other parts of a chimney but these two are on the front lines of keeping your chimney strong and efficient. We will be focusing on the ways to keep the chimney crown in good condition.

The chimney crown is a cement topper that surrounds the chimney flue. It is usually slanted downward to allow water to run off and away from the chimney flue and protect it from water damage. Cement is known for its strength but even cement is susceptible to water damage.

Rain, snow, and sleet beat on the cement, and it can become weathered. Cracks may form and if not repaired the water will continue to erode and force its way in. Then the chimney crown can no longer do its job effectively and the chimney masonry becomes vulnerable to chipping, spalling (flaking), and other types of water damage.

Installing a Chimney Cap

In the same way a baseball cap protects your head from the sun and even rain, a chimney cap is an extra layer of protection. The chimney cap fits on top of the crown and over the flue to shield it from water. A wire mesh surrounding it also keeps out animals and keeps sparks from flying out onto the roof. Installing a chimney cap is a recommended measure to ensure the long life and effectiveness of your chimney.

Should You Seal the Chimney Crown?

Now that you know how important the chimney crown is to the overall health of your chimney, you can see why protecting it should be a priority. Another way to protect the crown is by using a sealant. A silicone-based waterproof sealant can help extend the life of your chimney by guarding against the damaging effects of water. Using a sealant is a wise step. Some sealants claim to last up to 20 years.

If your chimney crown has deep cracks or extensive damage then you will need to look into chimney crown repair. The difference between a chimney crown repair and a complete rebuild has to do with the overall structural condition of the chimney crown. Even deep cracks can be filled with a thick cement mixture but missing cement, to the point that the walls of the flue are showing, will need a complete rebuild.

If a chimney has a strong crown and a secure cap it is less likely to experience the horrible effects of water damage. A fireplace is just one part of the system that allows your family to enjoy warmth and security during the coldest months. The other parts of your chimney such as the chimney masonry, crown and cap need maintenance and attention in order to continue to function properly. If your chimney has been a bit neglected, it’s not too late to take care of those maintenance issues before the harsh temperatures of winter are here.
