4 Problems Your Chimney Is Exposed To When Under Wet Conditions

by April Carlson

Getting your chimney inspected after the wet season in your area is highly important because chimneys experience a number of problems when introduced to wet weather. Here are four of the most common problems your chimney may suffer from:

  1. Rust: There are many metal materials that make up your chimney, which includes the flashing and firebox, which is inside of the chimney. If these metal materials are suffering from rusting, it becomes a problem because the rust will eventually start eating away at the metal. When there are holes left in the material, the metal pieces that make up your chimney will not perform as they should. For example, if there are holes in chimney's flue, then it is going to still let in debris to your home even when you have the flue closed. 
  2. Creosote Build-Up: During the wet season, when moisture gathers inside of your fireplace, it causes creosote build-up. This appears to be tar on the walls inside of your chimney. The problem with this is that once it builds up significantly, it can potentially cause a fire whenever you use your fireplace. This is because creosote can catch on fire and if it is going all the way up the walls, the fire can spread to the roof of your home. 
  3. Brick Damage: Most likely, your chimney is made of bricks and when this material is exposed to moisture it can lead to cracks in the material. The problem with this is that once the bricks are cracked, even in the slightest, it lets in more moisture to cause more problems. On top of this, once the cracks are severe enough, the bricks could fall out altogether. 
  4. Leaks: If there is a leak in the chimney, you need to hire professionals to come and repair it right away, otherwise it can lead to significant water damage in your home not to mention the inability to use your fireplace on cold, rainy nights. Leaks also bring in more moisture to the chimney even if the leak is small. You may notice a leak if you notice a significant breeze coming in through your fireplace. 

When you know what problems your chimney can be exposed to in moist and wet conditions, you can see why a chimney inspection after the wet season is so important if you want to continue using your chimney without issues in the future. For more information, talk to a professional like A Sound Chimney & Masonry LLC.
