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.
Chimney Company in San Anselmo, CA
Chimney work in San Anselmo is different because the town’s housing stock is different. Most homes here were built between 1905 and 1935, and their original brick chimneys are now 90 to 100 years old. That age changes everything: mortar joints spall, clay crowns collapse, and unlined flues carry creosote into spaces never designed for modern wood-burning. If you’re searching for a chimney company in San Anselmo, CA, call Alcott Chimney Sweep at (336) 863-3889. We’ll send a background-checked, identity-verified technician whose name and photo you’ll see before we arrive.
Why San Anselmo Homes Are Different
San Anselmo’s residential core grew up fast when the North Pacific Coast Railroad opened the Ross Valley to commuters, and builders responded with Craftsman bungalows and Colonial Revival cottages. Those homes are charming. Their chimneys are another story. Fireboxes were sized generously for large wood loads, and flues were often built without the clay tile liners that became standard later. Add a century of wood-burning, and you get creosote staging deeper than what we typically see in newer Marin developments.
Two more local factors compound the problem. First, San Anselmo’s narrow valley position channels more annual rainfall than coastal or bayside Marin, and that water works its way into exposed brick crowns and spalled mortar joints. Second, the bowl-shaped topography creates downdraft conditions when Pacific storms push wind over the ridgelines. Homeowners on the western hillside slopes above Sir Francis Drake Boulevard mention draft problems so routinely that we treat it as a standard part of the San Anselmo service conversation, not an anomaly.
Our Main San Anselmo Services
The two calls we get most from San Anselmo homeowners are for chimney sweeping and chimney inspection, with gas fireplace repair close behind as older gas units age out. Here’s what each job involves locally.
Chimney Sweep in San Anselmo
Sweeping a century-old San Anselmo chimney starts with removing what’s already inside it. The town’s dense oak, bay laurel, and redwood canopy supports a healthy raccoon and squirrel population, and uncapped flues on hillside streets above downtown almost always contain nesting debris. We clear that first, then remove the creosote: the tar-like, flammable buildup that causes chimney fires. Given the age of local flues, we pay close attention to glazed creosote, which forms when moisture from San Anselmo’s wet winters mixes with wood smoke. Chimney Sweep in San Anselmo

Chimney Inspection in San Anselmo
Most San Anselmo chimneys predate stainless-steel liner requirements, and many predate clay tile liners entirely. That means an inspection here isn’t a formality. We use a camera to look for spalled mortar, fractured flue tiles, and moisture intrusion, and we show you the photos before recommending anything. If a liner is failing, you’ll see it yourself. If the chimney can safely wait another season, we’ll say that plainly. No one at Alcott Chimney Sweep is rewarded for selling liners you don’t need. Chimney Inspection in San Anselmo

Gas Fireplace Repair in San Anselmo
Gas fireplaces in San Anselmo’s older homes are often conversions or early direct-vent units, and the common failures are predictable: thermocouples that won’t hold a pilot flame, clogged burner ports, and valves that stick after long idle summers. Ruben Castellano’s team troubleshoots before replacing, and if a part is needed, we’ll show you the failed component and quote the repair cost before any work begins. That’s the same written-price standard we apply to every job in San Anselmo. Gas Fireplace Repair in San Anselmo
