Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Berkeley
A chimney sweep in Berkeley typically costs $190 – $310 for a standard open fireplace with one flue, and most jobs are completed within 90 minutes to two hours. If you’re in the flats near San Pablo Avenue or higher up off Grizzly Peak, we know exactly what your flue is dealing with. Berkeley’s marine-layer fog carries salt from the Bay, and that salt attacks chimney crowns, caps, and flashing in ways you won’t see in Oakland or Walnut Creek. Call (831) 534-3789 for a free estimate, and we’ll put one of our Chimney Sweep technicians on your schedule.
Why Alcott Chimney San Francisco Is Berkeley’s Preferred Chimney Sweep Company
Berkeley homeowners call us because we answer two questions before we ever ring the bell: what will this cost, and who exactly is at my door. Every customer gets a written price before work begins, and every technician is background-checked, identity-verified, and announced to you by name and photo before arrival. That’s the Threshold Standard, and it’s not optional.
Ruben Castellano has run Alcott since 2002, and he trains every tech to treat Berkeley’s older homes with the respect they need. A 1915 Craftsman bungalow off College Avenue isn’t the same as a 2005 track home in Tracy. The masonry is different, the liners are different, and the way fog and damp interact with the flue is different. We know what to look for because we’ve seen it here, week after week, for years.
We serve all of Berkeley, from the Elmwood and Thousand Oaks neighborhoods up into the Hills, and from West Berkeley down to the Emeryville border. Our dispatch center is a live person, 24/7, so when you smell smoke at 11 p.m. during a winter storm, someone picks up. No voicemail tree. No callback queue.

Chimney Cleaning in Berkeley
Chimney cleaning in Berkeley means removing the creosote, soot, and debris that have built up inside your flue since the last burn season. That matters more here than in drier parts of the Bay because our fog season keeps masonry damp, and damp creosote hardens into a glaze that restricts draft and becomes a fire risk faster as it re-glazes over. A standard cleaning runs $190 – $310 for one flue, before any repairs.
Creosote and Soot Removal
We remove hardened third-degree creosote glaze from smoke chambers using professional rotary equipment, not just wire brushes. Soot from a season of fires in a Berkeley fireplace coats the flue walls, and when marine dampness sets in, that soot bonds with creosote into something that won’t brush out by hand. We get it out, then we show you photos so you can see what was in there.
Annual Sweep Before Burn Season
Most Berkeley homes with regular fireplace use should schedule an annual sweep in late September or October, before the first real cold snap. Fog and humidity start rising in late summer, so any moisture’s already in the flue by then. We sweep it, inspect the crown, check the cap, and you’re ready. If you use a wood stove more than three times a week in the Hills, consider twice a year.
Fireplace Cleaning in Berkeley
Fireplace cleaning in Berkeley goes beyond the flue, it includes the firebox, the damper, the smoke shelf, and the area around the hearth, and if you have a gas unit, our Gas Fireplace Repair - Berkeley service covers those components too. A full fireplace cleaning runs $140 – $250 depending on access and buildup. Berkeley’s older homes often have fireboxes with cracked firebrick, corroded dampers, and years of ash packed into spots that were never meant to hold it. We clean all of it.
Removing Hardened Fog-Driven Buildup
When fog rolls through the Golden Gate, it pushes salt-laden air into your uncapped chimney, and that moisture settles on the inside walls of the flue. What starts as soft soot becomes a hard, crusted layer over the course of a season or two. We use the right brushes and rods for the liner type you actually have, and we’re careful not to over-scrape older masonry that’s already stressed.
Smoke Chamber and Damper Access
Most Berkeley homeowners have never seen their smoke shelf. It’s the ledge just above the firebox that catches creosote and debris. If it’s never been cleaned, it’s likely packed. We open the damper, remove the buildup, and check that the damper seals so you’re not losing heat up the flue when the fireplace is cold. If the damper’s rusted shut from years of fog moisture, we’ll tell you what it costs to fix and whether it can wait.
Trusted Brands We Service in Berkeley
When a chimney component fails, what you replace it with matters. In Berkeley’s coastal air, the wrong metal corrodes in a couple of seasons. We service and install professional trade products from DuraFlex, Olympia Chimney, and Famco, and we keep common Berkeley-specific components in stock so you’re not waiting on a two-week order. Stainless steel caps, stainless flashing, and proper crown sealants are the difference between a chimney that lasts and one that fails five years from now. If your cap is galvanized and rusting, we’ll show you exactly what that’s costing you.

AfterCommon Chimney Sweep Problems We See in Berkeley Homes
- Salt-corroded galvanized caps and flashing. The fog off San Francisco Bay carries salt, and decades of it eats through standard galvanized metal at the seams. Stainless steel is the only long-term fix on a Berkeley chimney.
- Spalled brick crowns on exposed chimneys. Brick and mortar absorb fog moisture, then the salt crystallizes and breaks the surface apart. We see this on chimneys from the flats of North Berkeley all the way up to the Hills, and it lets water straight down into the flue liner.
- Hardened third-degree creosote glaze in damp flues. Berkeley’s marine-layer humidity turns first-degree creosote into a glossy, sticky glaze much faster than in dry inland climates. That glaze restricts draft and is the primary fuel for chimney fires.
- Cracked clay tile liners in pre-1940s masonry chimneys. Original liners on Craftsman bungalows and Victorians were never designed for decades of thermal stress under damp conditions. Once they crack, flue gases can reach the surrounding masonry, and the fix is relining.

FAQs About Chimney Sweep in Berkeley
Every year, without exception. The Berkeley Hills get more direct fog exposure than the flats, and salt-laden moisture accelerates corrosion of metal components and hardening of creosote. An annual inspection lets you catch a failing cap or crown before water reaches the liner. If you burn more than three times a week during the season, sweep twice a year. Call (831) 534-3789 and we’ll get you on the calendar before burn season starts.
Stainless steel is strongly recommended, and here’s the plain reason: the fog off the Bay carries salt, and salt eats galvanized metal at the seams and fasteners within a few years. A galvanized cap on a Berkeley chimney will rust through. Stainless costs more upfront, but it’s a one-time purchase, and the alternative means replacing a corroded cap every five or six years while water keeps getting in. We’ll show you the condition of your current cap and let you decide with your own eyes.
A Level 1 inspection is the standard annual check, covering the readily accessible portions of the flue, the cap, the crown, and the fireplace. A Level 2 inspection is required if you’re buying or selling a home, after a chimney fire, or if the home has had major renovations. In Berkeley’s pre-1940s homes, a Level 2 often includes a video scan that reveals cracked clay liners, hidden moisture intrusion, or clearance problems in the walls that no surface inspection can catch. Ask us which is right for you.
We cover all of Berkeley, from West Berkeley and the flats up through North Berkeley, the Elmwood, Claremont, Thousand Oaks, and the Hills above Grizzly Peak. Narrow streets and steep driveways are normal for us, and we bring the right equipment so roof access doesn’t mean trampling your landscaping. If you’re near Codornices Park or up by Tilden, we’re just as local as if you’re on Shattuck.
Creosote builds up, the fog does its work, and one of two things usually happens. Either the draft gets so restricted that smoke backs up into the firebox and fills the room, or a chimney fire starts silently in a flue you never think about. Neither is worth the $200 you saved. We treat this as maintenance, not emergency response, and a regular sweep keeps it that way. Call (831) 534-3789 and get it done before the next damp winter sets in.
