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 Company in Los Altos Hills, CA
Alcott Chimney Sweep is the chimney company Los Altos Hills homeowners call when they want a technician they can verify before the truck pulls up. Our work in Los Altos Hills runs heavy on multi-fireplace estate homes, aging clay tile liners, and the wildfire-risk realities that come with living in a CAL FIRE Very High Fire Hazard Severity Zone. If you need a sweep, an inspection, or gas fireplace repair, call (336) 863-3889 and you’ll speak with a live person, not a voicemail.
Why Los Altos Hills Homes Are Different
Los Altos Hills sits entirely within a CAL FIRE-designated Very High Fire Hazard Severity Zone. That single fact changes what chimney work means here. Creosote buildup or a missing spark arrestor on a hillside estate chimney isn’t a maintenance footnote. It’s a direct ignition threat to surrounding oak woodland. State law and Santa Clara County fire codes require spark arrestors on every chimney in this zone, and our technicians consistently find that requirement unmet on custom homes across the area.
The housing stock amplifies the stakes. Los Altos Hills is zoned for one-acre minimum lots, so we’re almost always working on large custom builds from the 1960s through the 1990s. Many have three or more masonry fireplaces, living room, master suite, family room. Those mid-century clay tile flue liners have been thermally cycled for decades. On sloped hillside foundations, they crack. We see it regularly.
The climate works against these older systems, too. The hills trap more marine fog and cool overnight air than Los Altos or Mountain View below. Homeowners burn earlier and more often, frequently with wood that hasn’t fully seasoned. That accelerates stage-two creosote glazing inside flue liners, and the persistent moisture degrades mortar joints and chimney caps faster than it does in the valley floor cities nearby.
Our Main Los Altos Hills Services
Homeowners in Los Altos Hills call us most often for two things: a thorough chimney sweep before burning season, and a camera-backed inspection when they’re buying, selling, or haven’t used a fireplace in years. Gas fireplace repair runs a close third on estate homes with aging gas log sets.
Chimney Sweep in Los Altos Hills
A standard Chimney Sweep in Los Altos Hills takes us inside the flue with industrial brushes and vacuum systems to remove creosote, the tar-like buildup that causes chimney fires. Because so many properties back up to open space preserves like Rancho San Antonio, we often find chimneys on the uphill side of homes packed with acorn caps, bay laurel leaves, and dried oak material funneled in by topographic wind patterns. That debris is a fire hazard separate from creosote entirely. We clear it all, and we check the spark arrestor while we’re up there because in Los Altos Hills, it’s code.
Chimney Inspection in Los Altos Hills
A Chimney Inspection in Los Altos Hills means a camera goes down the full length of the flue, and you see the footage for yourself. In a town where homes sit on sloped lots and flue liners date to the Johnson administration, hidden cracking is common. We document what we find, explain what’s urgent and what can wait, and hand you a written report before we leave. Nothing gets recommended without camera evidence you can see.
Gas Fireplace Repair in Los Altos Hills
When a gas fireplace in Los Altos Hills won’t light, produces weak flames, or shuts off mid-cycle, the cause is usually a failed thermocouple, a clogged burner, or a deteriorating gas valve. Our Gas Fireplace Repair in Los Altos Hills service covers diagnosis through replacement. Many of these units are original to houses built in the 1970s and 1980s, and parts are frequently still available through the trade supply channels we use. We’ll show you the faulty component before we replace it.
