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 Cleaning in San Francisco, CA
A chimney sweep in San Francisco typically costs $189-$289, and on a Victorian-era row house the job is rarely just about soot. The marine fog keeps old brick damp year-round, and the 1989 Loma Prieta earthquake left cracks in flue liners that most homeowners have never seen on camera. Whether you live in Noe Valley or the Richmond, a level-headed sweep starts with a real inspection, not a flashlight glance. Call (980) 580-8641 for a written quote before anyone steps inside.
Why San Francisco Homes Are Different
Most single-family homes in San Francisco were built between the 1880s and 1910s, attached to the house next door and framed around chimneys made of unreinforced brick and lime mortar. The 1906 and 1989 earthquakes shifted foundations and hairline-cracked flue liners in ways that are invisible from the firebox. Add in the near-daily marine layer that keeps masonry chronically damp, and you get mortar joints that erode from the inside while the exterior looks passable.
The Bay Area Air Quality Management District’s winter Spare the Air no-burn days complicate things further. Homeowners in the Castro, the Western Addition, and Noe Valley often go an entire season without lighting a fire, then burn on the one permitted evening. A chimney that sat damp and unused for months, with a crown crack nobody saw, gets asked to work hard suddenly. That’s the exact moment hidden damage stops being hidden. Many Victorian flues were also informally brick-capped or foam-stuffed after Loma Prieta and never properly reopened. Some homeowners have no idea the crown has been sealed for over thirty years.
Our Main San Francisco Services
Two services draw repeat calls from San Francisco homeowners more than any others: the firebox and the cap. Both tie directly to the age of the housing stock and the chronic damp that shortens the useful life of unprotected brick.
Fireplace Services in San Francisco
In a 1910s Edwardian flat, the fireplace is often the original wood-burning unit, with a shallow firebox, a deteriorated damper, and a smoke chamber that never got more than a patch coat. We evaluate the firebox, damper, and smoke shelf, and we document what we see. From gas logs to full firebox rebuilds, the work always starts with a camera so you see the same evidence we do. Fireplace Services in San Francisco includes a written scope and photo record on every visit.
Chimney Cap & Crown in San Francisco
San Francisco fog is unkind to crown mortar. A crown that cracked during Loma Prieta and sat exposed to decades of onshore moisture is now spalling, and a spalled crown lets water run straight into the flue and interior wythes. We replace or repair crowns and install caps that keep out rain, fog drip, and the pigeons that cluster on every block. Chimney Cap & Crown in San Francisco begins with a Level 2 camera scan because you cannot see a crown crack from the sidewalk, and neither can we until we’re on the roof.

BeforeAfterChimney Cleaning & Sweep in San Francisco
Most San Francisco sweeps are for chimneys that have not been used in months, which means we are not just removing soot, we are looking at what the moisture and inactivity did while nobody was watching. A Victorian built in the 1890s with a flue liner cracked by Loma Prieta will test differently than a 1920s bungalow, and the cleaning has to account for that. Every job includes a camera scan and a written photo record, which is why we built the Chimney Cleaning & Sweep process around NFPA 211 Level 2 documentation from the first visit.
Level 1 Inspection
Signs you need it
You burn the fireplace occasionally and want a basic visual check of the firebox, damper, and exterior chase before the season starts.
What it costs in San Francisco
A Level 1 inspection runs $119-$199, often bundled with the sweep price so you are not paying twice for the same arrival.
How we do it
We inspect the accessible portions of the firebox, damper, and exterior chimney, then hand you a written condition summary and photo record for $119-$199.
Level 2 Inspection
Signs you need it
You bought the home, the chimney has not been used in years, the house has been through an earthquake, or the flue was previously foam-stuffed and capped.
What it costs in San Francisco
A Level 2 camera inspection runs $300-$600, and on a hundred-year-old San Francisco chimney the camera portion is where every real finding comes from.
How we do it
We scan the full flue length with a camera, inspect the attic chase and rooftop crown, and produce a written report with labeled images for $300-$600.
Creosote Removal
Signs you need it
The damper is stuck from tar build-up, the room smells like a campfire days after the last burn, or the flue walls glisten in the camera.
What it costs in San Francisco
Creosote removal as part of a sweep is included, but a heavy glaze or Class III creosote removal adds $100-$250 in San Francisco.
How we do it
We mechanically break the glaze with rotary brushes and scrapers, then sweep the flue to bare liner and photo-document the result.
Annual Sweep
Signs you need it
You burn more than a few fires each winter, or the house is new to you and the last sweep date is unknown, which is true of most recent San Francisco buyers.
What it costs in San Francisco
A standard sweep runs $189-$289, and it is the single best insurance against a chimney fire in an urban rowhouse where a neighbor is six feet away.
How we do it
We sweep from the firebox up, drop a camera afterward, and record the flue condition before we call the job done.
What Chimney Cleaning & Sweep Costs in San Francisco
| Item | Typical range in San Francisco |
|---|---|
| Level 1 Inspection | $119-$199 |
| Level 2 Inspection | $300-$600 |
| Annual Sweep (full cleaning) | $189-$289 |
How often should I sweep my chimney in San Francisco?
Once a year is the baseline, even if you only burn a few evenings. San Francisco’s fog and no-burn days mean the flue sits damp and unused for long stretches, and the sweep is your chance to find damage before the next permitted burn.
Can you sweep a foam-stuffed Victorian flue?
We see sealed flues often in the Castro and Western Addition, where homeowners capped or foam-stuffed crowns after Loma Prieta and never reopened them. We remove the obstruction, sweep, and camera-scan because the underlying liner may need repair. Call (980) 580-8641 if you suspect your flue was sealed decades ago.
Chimney Repair in San Francisco
In attached San Francisco row houses, a cracked or failing chimney is not just your problem; it is a wall shared with the neighbor. Most of the repair work we quote starts as a small visible issue, bands of efflorescence on the interior wall, a drip stain on the ceiling near the chase, crumbling brick on the roof, and then the camera shows the spalling goes three feet deeper than anyone thought. Chimney Repair in this city is mostly about stopping water intrusion before the next fog season does more damage.
Mortar Repointing
Signs you need it
The mortar joints above the roofline look sanded down or recessed, with brick edges that are starting to shadow, common on every fog-exposed San Francisco rooftop.
What it costs in San Francisco
Repointing runs $1,000-$6,000 depending on how many courses of brick have lost their joint material, and San Francisco’s damp climate makes it a maintenance item rather than a one-time fix.
How we do it
We grind out the old lime mortar to a clean depth and repack the joints with a breathable lime and Portland blend so the brick can dry.
Spalling Brick Repair
Signs you need it
Brick faces are flaking or popping off above the roofline, and you see red grit in the gutter after a rain event or a week of heavy fog.
What it costs in San Francisco
Spalling brick repair runs $1,000-$6,000 depending on how many brick units have lost their face, and on a Victorian chimney the brick is often irreplaceable so we use matching reclaimed stock.
How we do it
We remove the spalled brick, reuse or match a salvaged San Francisco brick of the same era, and set it with a compatible mortar to stop the decay.
Chimney Waterproofing
Signs you need it
Efflorescence, a white chalky bloom, has appeared on the brick face or the interior lathe near the chase, and the brick stays dark for days after the fog lifts.
What it costs in San Francisco
Waterproofing runs $550-$800 for a stand-alone application after repairs, and on a fog-wrapped San Francisco chimney it is the only thing standing between new mortar and the next ten years of damp.
How we do it
We apply a siloxane-based water repellent that sheds liquid water while letting the lime mortar breathe, then note the date on the job record.
What Chimney Repair Costs in San Francisco
| Item | Typical range in San Francisco |
|---|---|
| Mortar Repointing | $1,000-$6,000 |
| Spalling Brick Repair | $1,000-$6,000 |
| Chimney Waterproofing | $550-$800 |
Will my rowhouse chimney replacement affect my neighbor’s wall?
Yes, most San Francisco chimneys are shared or abut a neighbor’s chase, so we assess the party wall condition before quoting. Our written scope names the shared surfaces and what access we need.
Is spalling worse in San Francisco than in drier cities?
Fog is the difference. Brick that stays damp 300 days a year cannot dry between rains, and spalling accelerates. We still see 1906-era brick failing on fog-side elevations. Call (980) 580-8641 for a camera look before the face falls off.
Chimney Liner & Rebuild in San Francisco
The most common liner issue in San Francisco is not rust, it is earthquake damage, cracks from the 1989 Loma Prieta quake that were never repaired because nobody ran a camera down the flue afterward. A cracked clay liner in a 120-year-old unreinforced masonry chimney lets heat and carbon monoxide reach the brick and the wood framing behind the ceiling. We quote Chimney Liner & Rebuild work only after the camera evidence is on the table, and we use DuraFlex and Copperfield steel liners sized to the existing flue.
Stainless Steel Liner
Signs you need it
The clay liner has visible cracks or gaps on the camera, or the old liner is spalling into the flue and blocking the draw.
What it costs in San Francisco
A stainless steel liner replacement runs $12,000-$25,000 in San Francisco, and on a three-story Victorian the roof access and scaffolding are a significant part of the number.
How we do it
We run a continuous DuraFlex stainless liner down the existing flue, insulate around it, and secure the top plate to a new crown.
Partial Rebuild
Signs you need it
The chimney above the roofline leans or has a visible offset from years of fog-driven erosion, but the firebox and lower flue are sound.
What it costs in San Francisco
A partial rebuild runs $10,000-$20,000 in San Francisco, and it usually includes a new crown, flashing, and waterproofing on the rebuilt section.
How we do it
We take the chimney down to the sound masonry, rebuild it with matching brick and lime mortar, and set a poured crown with a drip edge.
Full Chimney Rebuild
Signs you need it
The chimney is leaning, the brick has turned to powder in multiple courses, or the camera shows a liner collapse that makes the whole structure unsafe.
What it costs in San Francisco
A full rebuild from the firebox up runs $60,000-$80,000 in San Francisco, a number driven by scaffolding permits, party-wall coordination, and three-story roof access on a rowhouse.
How we do it
We rebuild from the firebox up using new masonry and a new liner system, phase the work so the neighbor’s wall is never left open, and document each stage.
What Chimney Liner & Rebuild Costs in San Francisco
| Item | Typical range in San Francisco |
|---|---|
| Stainless Steel Liner | $12,000-$25,000 |
| Partial Rebuild | $10,000-$20,000 |
| Full Chimney Rebuild | $60,000-$80,000 |
Do I need a new liner if my chimney was capped for 30 years?
Often yes. Being sealed kept the liner dry but did not undo earthquake cracks. We run the camera before recommending anything, and the quote only covers what the scan shows.
Can you reline a chimney without tearing down the brick?
Usually yes, if the masonry is sound. A DuraFlex or Copperfield steel liner drops down the existing flue, which means we do not have to open the wall of an attached San Francisco rowhouse.
Brands We Service in San Francisco
We stock and install liners and components from our brands, including DuraFlex, Copperfield, and Gelco, sourced through the Haven buying network to keep parts pricing predictable. Parts for common San Francisco liner sizes are typically available within the same week.

FAQs About Chimney Cleaning in San Francisco
For a standard sweep or Level 2 inspection, no permit is required. A partial or full rebuild often needs a Department of Building Inspection permit, which we identify in the written scope before any masonry work is scheduled. We handle the paperwork on jobs where it applies.
Yes, and shared chimneys are the norm in San Francisco’s attached Victorians and Edwardians. We name the shared surfaces in the written scope and coordinate roof or wall access with the neighbor’s schedule. The party wall is never opened without a plan.
Most cleaning and inspection visits are scheduled within the same week, and more urgent structural concerns are triaged over the phone by a live person, not a voicemail. For a free estimate, call (980) 580-8641 and tell us the neighborhood and what the chimney is doing.
