7. Don’t Forget the Chimney
Ideally, spring is the time to think about your chimney, because “chimney sweeps are going crazy right now, as you might have guessed,” says Ashley Eldridge, director of education for the Chimney Safety Institute of America.
That said, don’t put off your chimney needs before using your fireplace, Eldridge advises. “A common myth is that a chimney needs to be swept every year,” says Eldridge. Not true. But a chimney should at least be inspected before use each year, he adds. “I’ve seen tennis balls and ducks in chimneys,” he says.
Ask for a Level 1 inspection, in which the professional examines the readily accessible portions of the chimney, Eldridge says. “Most certified chimney sweeps include a Level 1 service with a sweep,” he adds.
Woodstoves are a different beast, however, cautions Eldridge. They should be swept more than once a year. A general rule of thumb is that a cleaning should be performed for every ¼ inch of creosote, “anywhere that it’s found.” Why? “If it’s ash, then it’s primarily lye — the same stuff that was once used to make soap, and it’s very acidic.” It can cause mortar and the metal damper to rot, Eldridge says.
Another tip: Buy a protective cap for your chimney, with a screen, advises Eldridge. “It’s probably the single easiest protection” because it keeps out foreign objects (birds, tennis balls) as well as rain that can mix with the ash and eat away at the fireplace’s walls. He advises buying based on durability, not appearance.
One other reminder: To keep out cold air, fireplace owners should keep their chimney’s damper closed when the fireplace isn’t in use. And for the same reason, woodstove owners should have glass doors on their stoves, and keep them closed when the stove isn’t in use.
