Have you noticed that your chimney starts to smell a little funky during the summer months? You’re not alone – this is a very common problem that many homeowners deal with as the temperature rises. There are a variety of different things that can cause your chimney to have an odor. Here’s why your chimney can start to stink in the summer and what you can do to freshen things up.
There are a few different things that can cause your chimney to smell during the summer.
Heat and Moisture – Heat and humidity can make these odors even more intense. The buildup of moisture in your chimney can cause a musky odor. This happens when rain and snow seep into your chimney during the winter. If there are any cracks in your chimney, the water can start to seep in, causing even further structural damage. Excess moisture can also cause mold to grow in your chimney, which can make the musky smell even worse.
Creosote Buildup – Another common cause of chimney odors is creosote buildup. Creosote is a byproduct of wood-burning fires. It can build up in large quantities when burning freshly cut or wet logs, which is why it’s so important to make sure you’re only burning dry, seasoned wood. This creosote buildup typically results in a smoky, charred odor. Creosote can be a major fire hazard, so you’ll want to consult with a chimney professional about your next steps.
It’s also very important to have a professional assess your chimney for any bigger issues. For example, if creosote buildup is the cause of the odors, a professional can conduct a deep clean to remove it. Water buildup and structural damage could require more intense professional repairs. These chimney professionals have the tools and expertise to remove the odor and help keep your chimney in good condition.
