Why San Francisco Homeowners Should Sweep *Before* the Fall Rush
San Francisco’s fall weather brings cooler nights and more fireplace use—but also hidden dangers. Creosote, a flammable tar from wood smoke, hardens faster in damp Bay Area chimneys, turning a routine sweep into an urgent fire prevention step. The **Chimney Safety Institute of America** warns that unswept chimneys are the leading cause of home fires during this season. Our team uses [CSIA-certified methods](services) to remove buildup *before* it becomes a hazard. [See our fall prep checklist](fall-checklist) for local warning signs like excessive smoke or soot in your home.
**What happens during your chimney service visit?**
Our visits include a **Level 2 inspection** (per [SF safety codes](sf-laws)) to check for cracks, blockages, or carbon monoxide leaks—common in older homes near the Marina or Pacific Heights. We’ll use brushes, vacuums, and cameras to clear debris, then provide a written report. Licensed and insured, we serve [South San Francisco](south-sf) to [Palo Alto](palo-alto).
