Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Francisco, CA
Alcott Chimney Sweep handles chimney cleaning, inspection, and gas fireplace repair across San Francisco. Most of the chimneys we work on belong to Victorian and Edwardian homes built before 1940, and they come with the full set of local complications: fog-driven moisture, dense row-house construction, and flues that have not been opened in years. If you need a sweep, an inspection, or a fireplace that will not light, call (831) 534-3789 and we will give you a straight answer about what the job involves.
Why San Francisco Homes Are Different
San Francisco’s housing stock is older and more tightly packed than almost anywhere else in the Bay Area. The Richmond and Sunset districts are full of attached homes that share chimney stacks, so a blockage in one flue can push smoke into the neighbor’s living room. We get those calls regularly. In Noe Valley, Pacific Heights, and the Mission, steep roofs and narrow side yards make roof access slower and more deliberate. The original brick chimneys on these homes are often over a century old, with mortar joints softened by decades of fog and coastal air. That moisture accelerates creosote buildup – the tar-like residue that causes chimney fires – and it also weakens the masonry itself. A chimney that has soaked up fog for 50 winters does not just need cleaning. It needs someone to check whether the structure is still sound before any fire is lit.
What that means for homeowners is simple: chimney work in San Francisco rarely stops at the sweep. It often leads to questions about liner condition, mortar repair, and whether a fireplace that has not been used in years should be used at all. We answer those questions with camera evidence, not guesswork, and we give you a written price before any work begins.
Styles & brands we work with
Our Main San Francisco Services
Most San Francisco homeowners call us for one of three reasons: the fireplace has not been cleaned in years, something does not look right and they want a documented inspection, or the gas fireplace will not stay lit. Each service has its own page with full pricing and details.
Chimney Sweep in San Francisco
A standard sweep removes creosote, soot, and any debris that has fallen into the flue since the last cleaning. In San Francisco, that debris often includes fog-dampened leaves, bird nesting material from the spring, and chunks of deteriorated mortar from old brick liners. We protect the hearth area, run professional brushes through the full flue, and leave the firebox clean enough to inspect. You will know what we found, what we removed, and whether anything needs attention before the next fire. Full details, including pricing, are on the Chimney Sweep in San Francisco page.
Chimney Inspection in San Francisco
An inspection matters most in older homes where the chimney predates modern building codes. We run a camera through the flue and document what we find, so you see exactly what we see – cracked flue tiles, gaps in mortar joints, or a liner that has failed. In attached row houses, we also check for cross-flue issues that affect the neighboring unit. The inspection report gives you the information you need to decide whether a repair is urgent or can wait. The Chimney Inspection in San Francisco page walks through what each level of inspection covers.
Gas Fireplace Repair in San Francisco
Gas fireplaces fail in predictable ways: pilot lights that will not hold, thermocouples that have worn out, clogged burner ports, and remote controls that stop responding. San Francisco’s frequent fog means many fireplaces sit unused for months and then get fired up on the first cold snap, which is exactly when their problems surface. We diagnose the issue, show you the failed part, and give you a written quote before replacing anything. The Gas Fireplace Repair in San Francisco page covers common repairs and what they cost.

Brands We Service in San Francisco
We install and service chimney systems built by our brands, including Olympia Chimney, Famco, and DuraFlex. When a liner or fireplace component needs replacing, we use the same professional-grade materials chimney professionals specify, not box-store substitutes. That matters in San Francisco, where the combination of fog, salt air, and old masonry punishes cheap parts quickly.

Prices in San Francisco run higher than the national average for two reasons: access is harder on steep roofs and tight row-house lots, and older masonry chimneys often reveal hidden damage once a camera gets inside. Every job starts with a written price before any work begins, so you will never get a surprise charge at the end. If a repair fails within the coverage period, the second visit is free – that is the 365-Day Done Right Promise, and it is included on every job.
