One of the hallmarks of being human is the ability to control fire. Even today, people naturally gravitate towards a warm, cozy hearth. While it is true that nothing really beats the comforting ambiance of a fireplace, neglecting timely maintenance may result in excess interior smoke, and in some cases delaying chimney repairs can cause a serious conflagration.
Many new homes are not designed to accommodate wood-burning fireplaces, but must still have chimneys to vent heat and residue from basement furnaces or boiler rooms. People living in warmer regions may only light up a fireplace on special occasions, or only during the chilliest winter months. This makes timely maintenance fairly easy to ignore until a problem arises.
Delaying routine inspections and repair can be deadly. Each year there are multiple home disasters caused by chimney fires. The single biggest problem is chronic neglect, resulting in a steady buildup of creosote. Creosote is the residue left by damp wood smoke and flames, and can accumulate comparatively quickly. Creosote burns easily, and can quickly transform a vent into a flaming torch.
Evidence of this buildup is not always obvious. One indicator is unusually black smoke flowing from vent, or back-filling the room whenever a fire is first lit. Without an inspection it may be impossible to tell just how much creosote exists, or how rapidly that buildup has accumulated. The best way to prevent this is by checking more than once each year.
A do-it-yourself check is relatively straightforward, and does not exceed the capabilities of most homeowners. For maximum safety, choose a calm day to prevent blowing soot, and be sure to wear a face mask. It is important to look closely at the the fireplace side, as well as on the roof. A good flashlight will be necessary, and sometimes an angled mirror helps to peer into hidden corners.
If any animal nests have been built inside, they must be taken down for safety. Even though it may not completely block the flue, an obstruction can lead to a buildup of carbon monoxide, and odorless but deadly gas. A simple screwdriver or knife makes a good tool for testing the thickness of the deposit. Accumulations greater than 1/4 inch should be cleaned away immediately.
Creosote deposits are only one possible hazard. Cracking is also an issue, and can be caused by settling foundations or harsh weather conditions. Older chimneys may be made of brick, and deteriorating mortar can cause them to topple during a strong storm or mild earthquake. Flashing is usually installed between the roof and brick, and if it works loose, water can damage the surface underneath.
In damp climates, moss should not be allowed to grow on the surface, and if there is a cap above the flue it may need cleaning or replacing. Homeowners who notice any obvious problems should alert their regular maintenance service. If repairs are necessary, have them done before lighting the fireplace or wood stove. A professional inspection and repairs can save money in the long run, and might end up preventing a disaster.
