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.

AfterFast, Reliable Chimney Sweep Across San Anselmo
A chimney sweep in San Anselmo typically costs between $189 and $289 for a standard open-flue cleaning, and most jobs are done in about an hour. If you’re burning wood regularly in one of the town’s older Craftsman bungalows or Colonial Revival cottages, we’re already familiar with your chimney’s quirks, and we’ll show up with a written price before anything starts. Call (336) 863-3889 to book, and we’ll confirm the technician’s name and photo before the truck leaves our office.
Why Alcott Chimney Sweep Is San Anselmo’s Preferred Chimney Sweep Company
San Anselmo homeowners call us because our Chimney Sweep team gets the town’s older housing stock. Most homes here were built between 1905 and 1935, which means we’re routinely working on original brick stacks that predate modern liner codes. That’s not a surprise to us; it’s the job. We know what a 1920s firebox looks like after a century of wood-burning, and we know what a Ross Valley rain season does to mortar crowns.
Ruben Castellano has built this company on a simple rule: nothing gets recommended until the homeowner sees the evidence on camera. You’ll know your technician’s name and see their photo before we arrive, and that technician will show you a photo ID badge at the door. Every person we send through a San Anselmo neighborhood has passed a background check and identity verification under the Threshold Standard. We don’t send strangers to your front steps.
Our phones are answered by a live person around the clock. If we’re already working in Fairfax or Kentfield, we can often route a sweep to central San Anselmo the same day we speak. If you live up in the hills above Sir Francis Drake Boulevard, the drive takes us a little longer, but the price you’re quoted doesn’t change mid-job.
Chimney Maintenance in San Anselmo
Chimney Maintenance in San Anselmo is not a luxury add-on for these homes; it’s the difference between a fireplace that drafts clean and a flue that quietly glazes over with creosote until it’s a fire hazard. Maintenance here means pulling the brush through to clear creosote and soot, checking the cap, and looking for the moisture damage that Ross Valley rain accelerates on exposed crowns. A basic maintenance sweep in San Anselmo runs $189 to $289 before any repairs.
Annual Sweeps for Active Burners
If you light fires more than a few times a month between November and March, plan on an annual sweep. San Anselmo’s older fireboxes were built for big wood loads, and the creosote they generate doesn’t announce itself until it’s thick enough to be dangerous. Once a year is the responsible cadence for a pre-1940 masonry chimney.
Pre-Season Checks for Occasional Fires
Even if you only burn on holidays, your flue still collects nesting debris from San Anselmo’s raccoon and squirrel population. An uncapped stack above a tree-lined street near the downtown corridor almost always has something in it. We check the cap, clear what’s there, and tell you plainly whether the flue needs a deeper look.
Chimney Sweep Services in San Anselmo
Chimney Sweep Services in San Anselmo start with the brush and end with an honest answer about what we found. A standard open-flue sweep here runs $189 to $289, and if we uncover a creosote condition that a brush can’t clear, you’ll see it on our inspection camera before we ask a dollar more. We perform Level 1 and Level 2 inspections, creosote removal, soot removal, and full fireplace cleaning on the town’s original brick masonry stacks.
Creosote and Soot Removal
Third-degree creosote, the tar-like glaze that fuels chimney fires, is a common finding in San Anselmo flues that have been burning for decades. It doesn’t brush out. When our camera shows it, you’ll see it, and then we’ll talk honestly about whether chemical treatment or resurfacing is actually warranted.
Fireplace Cleaning with Documentation
Every fireplace cleaning here includes a photo report of the flue interior. That’s not a premium add-on; it’s how Alcott works. You’ll see the before and after of your own stack, which matters when you’re trying to decide whether a reline recommendation is real or just a scare tactic.

Trusted Brands We Service in San Anselmo
When a San Anselmo chimney does need structural work, we carry and install the same materials chimney professionals specify: HeatShield resurfacing systems for deteriorated smoke chambers, Gelco crown repair products for spalled tops, and Olympia Chimney components for caps and chase tops. We don’t improvise with box-store substitutes. Because we work this town’s older stacks regularly, we keep common parts stocked for fast turnaround, which means a crown repair quote doesn’t wait a week for parts to arrive from a distributor.
Common Chimney Sweep Problems We See in San Anselmo Homes
- Unlined flues on century-old brick stacks. Most pre-1940 San Anselmo chimneys were built without any flue liner at all, or with clay tiles that have since cracked. A standard sweep doesn’t fix that; a camera inspection shows whether it’s a real hazard or can wait.
- Raccoon and squirrel nesting in uncapped flues. The oak and bay laurel canopy over San Anselmo’s hillside streets means uncapped chimneys collect animal debris fast. We routinely pull nests out before any brush can touch the flue.
- Spalled crowns and eroded mortar joints. San Anselmo’s Ross Valley position channels more rainfall than bayside Marin towns, and that water drives into exposed brick crowns. The result is mortar that crumbles and crowns that collapse at higher rates than we see in newer communities.
- Downdraft issues on hillside slopes. Homes on the western hillsides above Sir Francis Drake Boulevard get wind-driven downdrafts when Pacific storms push over the ridgelines. A chimney that smokes back into the house on stormy nights often needs cap or liner work, not just sweeping.
Pricing for Chimney Sweep in San Anselmo, CA
A standard chimney sweep in San Anselmo runs $189 to $289 for an open-flue fireplace. A Level 1 inspection adds roughly $49 to $99 when bundled with cleaning, and a Level 2 camera inspection, which we recommend on any pre-1940 home that hasn’t been inspected in years or recently changed hands, runs $150 to $300 depending on the stack’s condition and access. If a reline or resurfacing is needed, materials like HeatShield or a DuraFlex liner system add true cost, not markup, and you’ll see the camera footage that justifies the recommendation before you’re asked to approve anything. Estimates are free, in writing, and delivered before any work begins.

Yes, we serve the entire town, including the hillside streets above Sir Francis Drake Boulevard, the flats near downtown and San Anselmo Avenue, and the western slopes that catch Pacific storm winds.
