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.

Call (336) 863-3889 and you’ll get a live person, not a voicemail queue – day or night.
Here’s the thing about chimneys in Los Gatos: this town has some of the most varied housing stock in the South Bay. Victorian homes off North Santa Cruz Avenue sit a five-minute drive from mid-century ranches near Blossom Hill and custom hillside builds up Kennedy Road. Each one ages differently, and each one needs a sweep who knows what they’re looking at before they pull out the brushes. That’s us.
Why Alcott Chimney Sweep Is Los Gatos’s Preferred Chimney Sweep Company
Ruben Castellano has built Alcott Chimney Sweep around a simple idea: you should know exactly who’s walking up your driveway before they ring the bell. Every technician who services Los Gatos passes a background check and identity verification under the Threshold Standard – the same vetting protocol used across the Threshold Group family of home-service companies since 2002. We send you the technician’s name and photo ahead of the visit, and they carry a photo ID badge at your door. No exceptions, no “the guy called in sick so we sent someone else.”
Los Gatos homeowners tell us the same thing again and again: they’ve had chimney companies quote one number on the phone and a very different number after the inspection. We don’t work that way. You get a written price before any work begins – always. If we find something during the sweep, you see it on camera before you’re asked to pay for it. And every repair Alcott makes is covered by a written guarantee: if a repair fails within a full year, the second visit is free. That’s our 365-Day Done Right Promise, and it’s on every job – including yours in Los Gatos.
Chimney Sweep Services in Los Gatos
Chimney Sweep Services in Los Gatos follow the same job standard whether we’re working on a Craftsman bungalow near the downtown historic district or a multi-flue custom build in the hills above town. A sweep involves removing creosote – the tar-like byproduct of wood combustion that causes chimney fires – from the flue liner, clearing soot and debris from the smoke chamber and firebox, and confirming the damper operates correctly. We sweep the flue, not just the firebox, because the fire hazard lives in the stack you can’t see.
Level 1 and Level 2 Inspections
A Level 1 inspection comes standard with every sweep and covers the accessible portions of the chimney: flue liner condition, firebox, damper, and basic clearances. A Level 2 inspection goes deeper and uses a video camera to document the full interior of the flue from the roof down. In Los Gatos, we recommend a Level 2 on any masonry chimney rebuilt after the 1989 Loma Prieta earthquake – those structures are now past 30 years old and entering the window where hidden damage shows up.
Creosote and Soot Removal
Heavy creosote removal in Los Gatos runs $120 – $220 above the sweep price depending on glazing severity. Soot removal is included in the standard sweep and addresses the powdery black layer that coats firebrick and smoke shelves. Damp marine air moving through the Santa Cruz Mountain passes makes Los Gatos fireplaces run cooler than inland homes, which means creosote condenses faster – even in a fireplace you only use on weekends.

Chimney Cleaning in Los Gatos
Chimney Cleaning in Los Gatos means more than brushing out the flue. We clean the full system: flue walls, smoke shelf, damper assembly, and firebox. A single-flue cleaning with standard fireplace access runs $189 – $289. Homes with two or more fireplaces – common in the hillside custom properties that define Los Gatos’s upper neighborhoods – typically land between $340 and $520 depending on flue length, liner type, and creosote volume.
Annual Sweep
The National Fire Protection Association recommends an annual sweep for any chimney in regular use. In Los Gatos, that recommendation carries extra weight because the hillside neighborhoods fall inside California’s High Fire Hazard Severity Zone. A chimney that hasn’t been swept in two or three years isn’t just inefficient – it’s a fire liability in a town where wildfire season is a yearly reality.
Fireplace Cleaning
Fireplace cleaning covers the firebox floor, sidewalls, grate, and glass door assemblies. We remove ash, clean baked-on soot, and inspect firebrick for cracks or displacement. If you have a gas insert, fireplace cleaning includes burner inspection, ember bed maintenance, and glass panel cleaning – because even gas units accumulate residue that reduces efficiency and can create carbon monoxide build-up if the venting is obstructed.
Trusted Brands We Service in Los Gatos
Alcott Chimney Sweep carries and installs professional trade materials including DuraFlex liner systems, Olympia Chimney caps and dampers, Famco ventilation components, and Copperfield chimney products. These are the brands chimney professionals specify – not box-store substitutes. Because our Bay Area office maintains local parts inventory, Los Gatos customers don’t wait a week for a replacement cap or damper assembly when we’re already on the roof.
Common Chimney Sweep Problems We See in Los Gatos Homes
- Post-Loma Prieta rebuilds with cracked crowns. The 1989 earthquake’s epicenter sat less than ten miles from downtown Los Gatos, and thousands of masonry chimneys were rebuilt in the early 1990s. Those rebuilt crowns and flashing assemblies are now 30+ years old, and we regularly find cracks that let winter rain soak the smoke chamber – which homeowners mistake for a draft problem.
- Missing or corroded spark arrestors on hillside homes. California code requires functioning spark arrestors on all wood-burning chimneys in the High Fire Hazard Severity Zone. On nearly every hillside service call, we find arrestors that are missing, rusted through, or collapsed – a code violation most Los Gatos homeowners don’t know they have until we flag it.
- Glazed creosote on multi-flue masonry chimneys. Many hillside custom homes have two or three flues running through a single masonry stack. Owners often assume one sweep covers the whole chimney structure. It doesn’t – each flue is a separate fire-burning passage. A flue that went uncleaned for three or four seasons develops glazed, second- and third-degree creosote that requires chemical treatment before mechanical removal.
- Gas conversion neglect. Spare the Air restrictions have pushed many Los Gatos homeowners toward gas inserts. Those units still produce combustion byproducts and still need annual venting and burner inspection. We see gas fireplaces in town that haven’t been opened in five years, with burner ports clogged and logs misaligned – inefficient at best, unsafe at worst.

And here’s what makes Los Gatos different from every other town we serve: the post-Loma Prieta rebuild wave. The earthquake’s epicenter was in the Santa Cruz Mountains just a few miles from downtown, and the chimneys rebuilt in the years after it are now crossing the 30-year mark. Cracked crowns, failing flashing, spalling mortar joints – these are the quiet failures appearing across Los Gatos right now, and they’re exactly what a standard visual check from the ground misses. If your chimney was repaired or rebuilt in the early 1990s, it’s due for a structural look.
On a hillside custom home off Kennedy Road, we opened a Level 2 inspection on a post-Loma Prieta rebuild and found the chimney crown cracked all the way through, letting water soak the smoke chamber and original flue liner. We flagged a missing spark arrestor – a real fire-code violation in the High Fire Hazard Severity Zone – then swept two fireboxes, reinstalled a proper cap, and documented every flue so the owner could see which fireplace went with which liner before their next burn. That’s the kind of detail we check on every Los Gatos job, because we know what this town’s housing stock has been through.

FAQs About Chimney Sweep in Los Gatos
Yes – especially because of that rebuild. Masonry chimneys repaired or rebuilt in the early 1990s are now 30-plus years old, and in Los Gatos’s damp winter climate, crowns crack, flashing degrades, and mortar joints spall well within that window. An annual inspection catches these failures before they become water intrusion or firebox damage. If your chimney went through the post-quake rebuild wave, call (336) 863-3889 to have it looked at before burn season.
Yes. California code requires a functioning spark arrestor on all wood-burning chimneys, and hillside Los Gatos falls inside the High Fire Hazard Severity Zone – which means enforcement and compliance expectations are stricter. Many homes we sweep in the hills around Kennedy Road and Aldercroft Heights are missing arrestors entirely or have corroded units that no longer function. If you’re not sure whether yours is intact, we check it on every sweep and quote a replacement if needed.
Yes. Each flue is a separate passage that carries smoke and creosote from a specific firebox, and a sweep through one flue doesn’t clean the others. In large hillside custom homes – which are common across Los Gatos – we routinely see homeowners who assume the whole stack is clean because they swept the fireplace they use most. The unused flues are often the ones with the heaviest creosote build-up. Call (336) 863-3889 and we’ll quote you per flue so there’s no confusion.
Yes, but not the same kind. Gas inserts don’t produce creosote, but they do produce combustion byproducts that coat the venting, and the burner assembly itself requires annual inspection and cleaning to prevent carbon monoxide build-up and keep efficiency where it should be. With the Bay Area Air Quality Management District’s Spare the Air restrictions pushing more homeowners toward gas, we see more inserts every year in Los Gatos – and most of them haven’t been serviced since install.
Los Gatos runs cooler than San Jose to the north, with winter nights regularly dipping into the mid-30s, and the damp marine air coming through the Santa Cruz Mountain passes makes fireplaces run cooler and dirtier. That cooler, moisture-heavy burn cycle accelerates creosote condensation inside the flue – so a Los Gatos chimney that sees regular weekend use typically needs a sweep every 12 months, and sometimes more often if you burn softwoods or unseasoned wood.
If your chimney hasn’t been swept this year – or if you’re looking at a 30-year-old rebuild with cracks you can’t see from the ground – call us. (336) 863-3889. Ruben and the Alcott team will give you a straight answer, a written price, and a technician whose name and face you’ll know before they knock.
