Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Company in San Francisco, CA
Alcott Chimney Sweep is a San Francisco chimney company built around a simple promise: you’ll know exactly who’s coming to your door, what the work will cost, and what’s actually happening inside your flue before anyone picks up a tool. That matters more here than in most cities. San Francisco’s housing stock is dominated by Victorian and Edwardian buildings constructed between 1880 and 1915, and their brick chimneys now carry over a century of fog, earthquakes, and code changes. Most of what we do in San Francisco starts with understanding that history. Call (336) 863-3889 and a live person answers, day or night.
Why San Francisco Homes Are Different
San Francisco brick chimneys weren’t built for the conditions they face now. The marine fog that rolls through the Sunset, Richmond, and Twin Peaks corridors keeps brick faces and mortar joints damp for months at a time, which accelerates erosion and interior spalling even in fireplaces that seldom see a fire. A chimney that has never had a visible problem can hide flue-liner cracks or separated mortar joints for years, because the damage happens slowly and out of sight.
Then there’s the 1906 earthquake and the rebuilding wave that followed it. Many of the city’s chimneys were hastily rebuilt after that disaster, and plenty were never retrofitted with a clay liner at all. Bare brick flues are common in pre-1920 flats and single-family homes. When you add the 1989 Loma Prieta earthquake to that picture – an event that cracked flue liners in homes across the city, often without any visible sign from the outside – chimney cleaning in San Francisco almost always doubles as a structural assessment. That’s why we camera-inspect during a standard sweep here. It’s not an upsell; it’s the only reliable way to see what a century of moisture and seismic movement has done behind the brick.
Our Main San Francisco Services
Most San Francisco homeowners call us for one of two things: a chimney sweep for a fireplace that hasn’t been used in years, or a chimney inspection before buying an older home. Below are the three services we provide throughout the city, each with its own dedicated page.
Chimney Sweep in San Francisco
A chimney sweep in San Francisco typically begins with locating the flue serving your specific unit, because in this city’s two- and three-flat Victorians, a single exterior chimney stack often contains separate flues for separate residences side-by-side. Mislabeled or accidentally shared flues turn up regularly, and using the wrong opening can be a fire-code violation. We remove creosote – the tar-like buildup that causes chimney fires – and then camera-inspect the flue while we’re in there. In damp San Francisco air, what looks like a simple cleaning can uncover moisture damage that needs attention before your next fire. Full details on our Chimney Sweep in San Francisco page.
Chimney Inspection in San Francisco
A chimney inspection in San Francisco is the smartest first move for anyone buying a pre-1920 home, because what you can’t see is exactly what the seller didn’t disclose. We run a camera from the firebox to the chimney cap and document everything: cracked flue liners, separated mortar, partial blockages, and hidden earthquake damage from 1989 that may have gone undetected for decades. You get a photo report showing what we found, so you’re never deciding on a recommendation you can’t see for yourself. See the Chimney Inspection in San Francisco page for what each inspection level covers.
Gas Fireplace Repair in San Francisco
Gas fireplaces in San Francisco’s older flats often sit inside what was originally a wood-burning hearth, which means the gas line, venting, and old chimney meet in ways that newer homes never see. We service and repair gas fireplaces throughout the city, working with professional trade brands like Famco and Copperfield rather than box-store substitutes. Whether it’s a pilot light that won’t stay lit, a thermocouple that’s failing, or venting that’s been routed into an aging flue, see the Gas Fireplace Repair in San Francisco page for specifics.

FAQs About Chimney Company in San Francisco
For most neighborhoods, we can schedule within one to two business days. If you have an active chimney issue – smoke backing into your living room or a strong odor – call (336) 863-3889 and we’ll prioritize your visit.
For single-family homes, standard sweeps and inspections don’t require permits. For multi-unit buildings or homes in historic districts, repairs that alter the exterior chimney may need approval. We’ll flag that before any work begins.
Moisture damage inside flues that have never been lined. The city’s fog keeps brick damp year-round, and in homes built before modern liner standards, that moisture quietly erodes mortar and brick from the inside. A camera inspection shows the full picture.

- Stuart L."Left no soot anywhere. Even brought a vacuum with a sealed filter. I'd use them again every fall."
- Beth H."Gas fireplace pilot kept going out. Cleaned the burner, replaced the thermocouple, and explained what failed. Works first try now."
