One of the most common questions that clients ask about involves how to repair a chimney crown in Marietta. The chimney crown is located at the top of your chimney. It works to keep water from seeping into your chimney. If it gets a crack in it, it won’t be able to do its job, and water will end up in your chimney. To prevent this from happening, you need to get cracks filled as soon as possible or repair the crown right away. So what causes cracks in your chimney crown? Here are 4 culprits that you should know about.
It’s hard to tell if your chimney crown was installed correctly, but improper installation can play a huge role in how well it will withstand the other culprits of cracks. It should be made of quality material that will hold up for as long as possible. If your crown wasn’t installed correctly, you should replace it with a crown that is made of quality material and make sure that it’s firmly sealed to your chimney with a sticking agent and a waterproofed seal.
Loose bricks, a shift in the chimney structure, and other issues can cause cracks in your chimney crown. When this happens, they create spaces that allow moisture to get inside of the chimney crown. The increased moisture leads to greater cracks in your chimney crown, which will continue to allow more water to seep into your chimney. It’s important to check your chimney crown on a regular basis, so you can identify any structural changes that can affect your chimney. When you notice them, you can repair the structural damages to make sure that the chimney crown isn’t affected.
Rain, wind, and snow can affect your chimney crown, too. Wind can wear down your chimney crown as it beats against your home, and the rain and snow will send moisture into the small cracks and enlarge them along the way. One of the biggest issues involving the weather is the changes in temperature. Heat and cold can work to break down the chimney crown as it expands and shrinks with the weather.
Even minor seismic activity can cause small cracks in your chimney crown. Then, the other culprits can cause the crack to grow over time. If your area experienced any seismic activity, you should have your chimney crown examined for any cracks. Small ones can be filled in, so they won’t continue to grow and cause more issues for you.
There really isn’t much that you can do to prevent cracks from forming in your chimney crown. You can’t control the weather. You can’t prevent seismic activity, and you never know when other structural issues will occur. What you can do, however, is pay attention to your chimney crown and take care of the cracks as soon as they happen.
