When & with what equipment?

Keeping chimneys clean is the other key step in preventing chimney fires. If you don't use your fireplace very often, or you just moved, you might not know whether your chimney is clean or not.

The following signs indicate a chimney in need of a cleaning:

  • Burned wood odors coming from the fireplace when it's not being used.

  • Fires that seem to burn poorly or that dump a bunch of smoke into the room.

  • A black damper. Since it sits right above the firebox, the damper is often the easiest thing to see and reach. And it gets caked with creosote. Look or reach inside, and see what you can find. If you see black gunk or you can pull out chunks of the stuff, there's a good amount of creosote built up inside.

How often you need to clean your chimney depends a great deal on how much you use it. The kinds of fires you build and the type of wood you use also govern frequency. As a rule of thumb, it's a good idea to have chimneys cleaned at least once a year, usually before cold weather sets in. Some people prefer to do it in the spring, and some chimney sweeps offer special promotions at this time of year to keep business going. This is fine, too, but scheduling a fall cleaning will also clear out anything that might have fallen into the chimney during the summer.

Most people hire chimney sweeps. We recommend it as well. It's dirty work, and not something that's okay to do half-way. A certified, well-trained sweep will do a better job in a shorter amount of time than you can. Look for someone who is credentialed by the National Chimney Sweep Guild or the Chimney Safety Institute of America.

You can, however, clean your chimney yourself. Here's what you'll need:

  • Ladder for climbing onto the roof.

  • Drop cloth or old sheet to cover fireplace opening, and additional drop cloths or sheets to cover any rugs or furniture in the area.

  • Duct tape or another product for attaching the drop cloth or sheet to the fireplace opening.

  • Vacuum cleaner with crevice attachment. If you plan on making chimney cleaning a regular habit, you might want to think about investing in a vacuum designed for exactly this.

  • Chimney rod and brushes. You can buy these at some hardware and home stores, or from a chimney sweep supplier. Some fire departments keep brushes and rods for people to borrow to clean their chimneys.

  • Stiff-bristled cleaning brush. Buy one with a long handle for easier access to the damper.

  • Broom for sweeping up ash and other debris.

  • Eye protection, gloves, and a dust mask. While you can get away with a cloth mask, a respirator mask is strongly recommended. You don't want to inhale creosote dust or soot.

  • Old clothes. Wear things you won't mind getting dirty.

  • Flashlight, for checking your work.
