The thing about chimneys is you never really know what's going on inside them? It's important to have an annual chimney inspection to ensure your chimney doesn't have any major cracks and isn't accumulating an excess of the highly flammable creosote. We recently performed a chimney inspection and chimney cleaning for a home in Delano, MN. Take a look at the before and after chimney cleaning pictures found below.
Not only was this chimney filled with creosote, the cap was completely plugged up with the highly flammable material and was quite literally, a chimney fire waiting to happen.
