Fireplace & Wood Stove Chimney Sweeping

San Francisco’s old brick homes and modern condos with fireplaces share one deadly flaw: **creosote buildup**. This tar-like residue isn’t just dirty—it’s **highly combustible**, and a single spark from a dry winter fire can turn your chimney into a torch. Our **chimney sweep** in San Francisco uses **rotary brushes and powerful vacuums** to strip away even the toughest deposits, including the **glassy, fire-prone Stage 3 creosote** that forms in neglected flues. We don’t just clean; we **verify clearances** to ensure your chimney meets **SF’s strict safety codes** for insulation and spacing. Skip this step, and you’re gambling with your home’s structure—and your family’s health. **Book now before the next Diablo wind season hits.**

Carbon Monoxide (CO) Safety Inspection

You won’t smell it, but **carbon monoxide from a faulty chimney** is a silent killer—especially in San Francisco’s dense housing where ventilation can be poor. Our **CO safety inspection** goes beyond visual checks: we **test for gas leaks** using handheld monitors and **inspect for cracks, rust, or blocked flue tiles** that let CO seep into your home. Last winter, a **Pacific Heights homeowner** nearly suffered CO poisoning because their **1920s masonry chimney** had a hairline fracture—undetectable until we scanned it with **thermal imaging**. We’ll flag these risks **before** your detector even beeps. **No other San Francisco chimney sweep combines this level of diagnostic rigor with a cleanup.**

Chimney Relining & Repair

A chimney isn’t just a pipe—it’s a **system**, and when **mortar crumbles, rust eats through metal, or tiles shift** (common in SF’s seismic zones), your fireplace becomes a **liability**. Our **relining service** uses **high-temperature stainless steel or ceramic liners** to seal gaps that let **smoke, sparks, and CO** escape into your home. We’ve repaired chimneys in **Noe Valley row houses** where **brick deterioration** caused smoke to back into living rooms, and in **Mission District condos** where **improperly installed flues** created fire hazards. **SF’s Building Code requires relining for certain repairs**—we handle the paperwork and the work, so you’re **code-compliant and fireproof**. **Don’t wait for a chimney fire to find out your liner’s failing.**

Masonry Chimney Restoration

San Francisco’s **Pacific Ocean breezes and winter rains** take a toll on chimneys faster than you’d think. **Leaking mortar, spalling brick, and water-damaged crowns** don’t just look bad—they **compromise your chimney’s integrity**. Our **masonry restoration** includes **tuckpointing** (replacing eroded mortar), **brick repointing**, and **waterproofing** with **flexible sealants** to prevent **moisture intrusion**—the #1 cause of **chimney collapses**. We’ve stabilized chimneys in **Alamo Square** where **salt air corrosion** weakened joints, and in **Sunset District** homes where **poor drainage** caused **foundation cracks**. **SF’s retrofitted homes** (especially those with **added fireplaces**) often need this work—**we’ll make your chimney as strong as the day it was built.**

Emergency Chimney Fire Response

If you see **orange flames in your chimney, excessive smoke, or the smell of burning wood**, you’re in **emergency mode**. Our **chimney fire response team** arrives **within 90 minutes** (faster than most SF fire crews) with **Class A fire extinguishers, thermal cameras, and containment gear** to **stop the blaze and assess structural damage**. Last November, we **saved a Richmond home** from a **full-blown chimney fire** by **sealing the flue and redirecting smoke** while the owner called 911. **Insurance companies prefer** (and often **require**) licensed chimney sweeps for fire claims—**we’ll document every step** so your policy covers repairs. **Your chimney’s on fire. Call us first.**
