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.
Newer homes are usually connected to natural gas, and many are not designed for wood burning fireplaces. Regardless, there must still be a safe and effective way to release the hot gases and residue from basement boilers or furnaces. In warmer regions, a fireplace may be used only occasionally during the winter, and maintenance becomes relatively easy to ignore.
The cost of procrastination can be high. Chimney fires cause a predictable number of losses each year, most caused by a steady buildup of creosote inside the vent itself. Creosote is the remaining chemical residue of the fire and smoke that high-moisture content wood produces. It can build up rapidly, and burns very quickly at astonishingly high temperatures.
The signs of that buildup are not always apparent. One indicator is consistently dark smoke exiting the top, or problems with lighter smoke back-flowing into a room even when the flue is opened properly. The only accurate way to gauge the volume and rate of deposit is to make an inspection more often. A thorough checkup takes a relatively short time, and need not be costly.
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 there is evidence of a rodent or bird nest blocking the exit, it will have to be removed. Even though this inconveniences the animals, a backup can result in excess carbon monoxide, and odorless gas that can be quickly fatal. The layers of creosote can be examined best using a screwdriver or long knife to cut through the deposit. If it is greater than 1/4 inch deep, do not use the fireplace until it is cleaned.
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.
Moss is picturesque, but should not be allowed on the chimney surface. Caps designed to keep out debris often need cleaning or repair. When a homeowner discovers these or similar issues, it is time to call for professional help with the repairs. Never light a fire if there is even a small suspicion of trouble. Getting the maintenance work done saves money and ultimately prevents disaster.
