At first glance, chimneys seem very robust. They live outside all year, exposed to the elements, and can withstand hundreds of degrees worth of heat, fire after fire. Despite all of this, however, chimneys do need some regular care to keep up with these high demands. Industry experts strongly recommend having the chimney swept and inspected at least once every year and for good reason. Failure to keep up with chimney maintenance can have some devastating consequences.
For wood burning fireplaces and stoves, the chimney will contain a buildup of a material called creosote. This black, tarry material clings to the surface of the chimney and can build up to the point of blocking air flow. Creosote is also highly flammable and is the cause of many destructive chimney fires. It burns at a much higher temperature than wood or gas, and once burning, it can be very difficult to extinguish. To keep your home and family safe, having a chimney sweep remove the creosote is imperative.
Debris found in the chimney can also take the form of an obstruction that reduces or blocks the flow of air. A common obstruction in the chimney is an animal and its nest. Warm chimneys attract small animals like birds, squirrels and raccoons that need a cozy space to wait out the winter. Unfortunately, this means trouble for the home owner. When the toxic fumes from the fire cannot escape through the chimney, they end up in the house. Not only does the creosote and soot leave messy, black residue on walls and furniture, but this lack of ventilation can actually be dangerous. Carbon monoxide, a product of combustion, can cause death when inhaled in high enough concentrations. It also has no color, smell, or taste, making it impossible to detect without relying on a special detector. To avoid the dangers of carbon monoxide from the fireplace, have a chimney sweep out every year.
Chimney inspections should also be done every year. The inspector examines the chimney from inside the house and from the roof to determine its structural soundness. A common problem that inspectors uncover is water damage. In a masonry chimney, water can enter the brick and mortar and cause cracking or even collapse. In all types of chimneys, water can also cause damage to the interior. If the flue lining is made of metal, water exposure can lead to rusted cracks or holes, which then exposes the house to further water damage, carbon monoxide leaks, and potential house fires. A simple inspection could determine if the chimney cap needs to be replaced, which can prevent these problems most of the time.
All in all, failure to keep up with chimney maintenance could cost you money in repairs, your house, and even your life.
