Chimney Cleaning in Los Angeles: What You Can Do Yourself vs. When to Call Immediately

Los Angeles is not a city most people associate with chimney maintenance, but the metro area's millions of homes — from the Craftsman bungalows of Pasadena and the Spanish Colonials of Los Feliz to the mid-century moderns of Laurel Canyon and the tract homes of the San Fernando Valley — include a remarkable number of functioning fireplaces. These are used during the cooler months from November through February, when hillside neighborhoods like Beachwood Canyon, Mount Washington, and the Hollywood Hills see evening temperatures regularly dip into the 40s. Even infrequent use creates chimney maintenance needs, and in seismically active Southern California, those needs are more complex than in most places.

There are practical owner-level chimney checks for every Los Angeles homeowner. Each fall, inspect your chimney cap from the ground or from a safe upper-level view. LA's hills and canyons are home to an abundance of wildlife — coyotes, raccoons, opossums, and a wide variety of birds — and the chimneys of infrequently used fireplaces in hillside homes from Silver Lake to Bel Air are prime nesting targets. A chimney cap prevents animal intrusion during the long months between fires. Look at the exterior chimney masonry for visible cracks in mortar joints or at the crown — this is especially important in Los Angeles, where seismic activity can stress masonry even in earthquakes too small to feel strongly. Test the damper operation before each use. Shine a flashlight up the flue to check for animal nesting or debris before lighting the first fire of the season. In LA, where fireplaces are often used infrequently, it is also worth burning a hot fire with dry, seasoned wood to encourage proper draft before settling into lower-intensity use.

Call a certified chimney technician immediately when any of the following conditions exist. Visible creosote — particularly the shiny, glaze-like stage-three creosote that infrequent fires in LA fireplaces can produce — is a fire hazard requiring professional rotary cleaning. Cracked flue tiles are a serious concern in the Los Angeles region: seismic activity on the many fault systems throughout Southern California, from the San Andreas to the Elsinore and Whittier faults, can crack clay flue liners in ways not visible from below. Any visible cracking in the flue liner must be assessed by a professional before further use. A smoke smell in the house when the fireplace is not in use signals a blocked or improperly drafting chimney. Animal nesting is extremely common in Los Angeles chimneys given the rich wildlife environment, and professionally removing it before lighting a fire is essential. If your Los Angeles fireplace has not been used in three or more years, a Level 2 inspection using video camera technology is mandatory before use. After any significant earthquake — particularly those above 4.0 in magnitude — have your chimney professionally inspected even if it looks intact from outside.
