"Cap It Right, Keep It Tight – Flue Cap Solutions!"

We went to Florissant, MO to remove and reinstall a flue cap. Installing a flue cap is one of the simplest and most effective ways to protect your chimney and home from the elements. A flue cap acts as a barrier that keeps rain, snow, and debris from entering the chimney flue, which can lead to moisture damage, rust, and even structural issues over time. Without a cap, water can seep into your chimney system and fireplace, causing deterioration of bricks, mortar joints, and metal components. It also prevents leaves, twigs, and other debris from falling in and creating blockages that could restrict airflow and increase the risk of smoke backing up into your home.

Beyond protecting against the weather, a flue cap also helps keep animals out. Birds, squirrels, and raccoons often seek warm, enclosed spaces to nest—and your chimney can be a prime target if left uncapped. Not only can this cause dangerous blockages, but it also poses fire and health hazards. Many flue caps also include a spark guard, which helps prevent embers from escaping the chimney and igniting nearby materials. Overall, adding a flue cap is a small investment that delivers big benefits—extending the life of your chimney, improving safety, and keeping your home protected year-round.
