Your chimney system's role in your home is an important one. As you use your fireplace or stove, high heat, flammable debris and toxic gases are produced as a byproduct of combustion, and your chimney holds those byproducts and routes them up and out of your living area. Doing so protects your home and the people in it, and, more simply, allows you to more safely enjoy having a warm fire in your home. When your chimney system isn't working properly, you could end up with a smelly, smoky space, or even a chimney fire that spreads to your home.
