What are the most common problems?
Chimneys are prone to a few frequent problems that homeowners should watch for. Creosote buildup along the flue liner is one of the most frequent problems. Burning damp wood or low-heat fires can lead to this issue. Creosote is a highly combustible material, and if it builds up enough it can cause a fire when the embers move through the flue.
Chimney blockages—particularly in the stack or liner—pose a real safety concern for your fireplace or stove. While soot and creosote are common culprits, leaves, branches, or nests can also block the flue—especially without a chimney cap. If the flue is blocked, smoke and combustion byproducts can be trapped inside rather than venting out properly. This makes your heating system less efficient and increases the danger of smoke intrusion or CO buildup. To prevent these problems, schedule regular chimney inspections and thorough cleanings.
