Which problems come up frequently with chimneys?
Several issues can arise if a chimney isn’t properly maintained. Creosote buildup along the flue liner is one of the most frequent problems. It often occurs when low-quality wood is burned or if the fire isn’t producing enough heat. Because creosote is extremely flammable, it can ignite when hot embers travel up the chimney.
A clogged chimney flue or stack is a common issue that can hinder the proper use of your heating appliance. While soot and creosote are common culprits, leaves, branches, or nests can also block the flue—especially without a chimney cap. When the flue is obstructed, it restricts airflow and can prevent smoke, gases, and other byproducts of combustion from properly venting outside. Blocked chimneys can lower your fireplace’s efficiency and raise the chance of smoke backup or carbon monoxide poisoning. Routine chimney maintenance helps detect and clear these blockages before they become serious hazards.
