We remove toxic buildup, inspect for issues, and check caps/toppers.
A chimney is a great but potentially dangerous addition to your home.
Wood fires create Creosote, a dangerous and toxic byproduct of the wood burning. While this would normally exit your home via the chimney, it can build up and lead to back flow into your home.
By cleaning/sweeping your chimney, you remove the buildup of this byproduct and prevent back flow from occurring.
