Chimney Maintenance

Chimney Maintenance

All chimneys (metal or masonry) require special care so smoke and flue gases are properly vented. Have your chimney inspected and cleaned before each heating season. Some of the things to look for include the items in this picture:

Besides having your chimney inspected, you should also have it cleaned regularly to reduce creosote. Creosote accumulates in stovepipes and chimneys and may ignite unless it is removed periodically. Creosote is mainly caused by:
  • Slow smoldering (smoky) fires.
  • Cool surfaces (such as exterior chimneys).
  • Burning unseasoned wood.
Creosote buildup varies with the type of fires you burn, heater design, draft and the type of chimney. A rule of thumb is to clean a chimney whenever there is more than 1/8-inch to 1/4-inch of creosote. At the very least, you need to clean the chimney on an annual basis, before the start of the heating season. Your chimney may need to be cleaned more than once per year depending on your individual use. Chemical chimney cleaners are generally not effective in reducing creosote buildup.
