3. Preventing Destructive Chimney Fires Caused by Creosote Buildup and Obstructions

Creosote is a highly combustible, tar-like residue that adheres to the interior walls of your flue every time you burn wood. When leaves, twigs, or animal nests block the top of your chimney, smoke cannot escape efficiently, causing creosote to accumulate at an accelerated rate.

Water is the ultimate enemy of brick and mortar structures, particularly in our region where temperatures fluctuate dramatically above and below freezing. A chimney crown is the concrete slab cast on top of the masonry stack designed to shed rain away from the flue opening. Without an overhang cap protecting both the flue and the crown shoulders, hairline cracks absorb moisture that expands when frozen, breaking chunks of concrete away.
