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.
Fast, Reliable Chimney Inspection Across Los Altos Hills
Chimney inspection in Los Altos Hills typically costs $189 – $389 for a Level 1 visual check and $289 – $549 for a Level 2 camera inspection, and most homes here need the camera work because of aging clay-tile flue liners. We’ve worked Los Altos Hills long enough to know that a one-acre estate off Fremont Road or La Paloma Road rarely has just one fireplace. You’ve likely got two, three, or four masonry fireplaces sharing flue systems built decades ago, and the marine fog that settles over these hills means you’re burning earlier and more often than your neighbors down in Los Altos. Call (336) 863-3889 and we’ll schedule an inspection with a technician whose name and photo you’ll see before we arrive.
Why Alcott Chimney Sweep Is Los Altos Hills’s Preferred Chimney Inspection Company
We show our work. That’s the short version. When our team inspects a chimney in Los Altos Hills, every finding gets documented on camera and shown to you on screen before anyone recommends a repair. No vague warnings about “deterioration.” No push toward a liner replacement you can’t see. Ruben Castellano built Alcott Chimney Sweep on a simple rule: if we can’t show it to you on the camera, we don’t ask you to pay for it.
The technicians we send into Los Altos Hills are background-checked and identity-verified under the Threshold Standard, a vetting process that’s been in place since Alcott opened in 2002 as part of the Threshold Group family. You’ll know your technician’s name, see their photo before they arrive, and they’ll show a photo ID badge at your door. Every job gets a written price before any work starts, and every repair carries a written guarantee, the 365-Day Done Right Promise means if a repair fails within a year, the second visit is free. We stock professional-grade materials like Olympia Chimney and Copperfield parts, not box-store substitutes, and our crews serve Los Altos Hills locally from the brand’s San Francisco Bay Area office.
Fireplace Inspection in Los Altos Hills
Fireplace Inspection in Los Altos Hills means looking at more than the firebox. The homes here, mostly custom estates built between the 1960s and 1990s on one-acre minimum lots, frequently have fireplaces in the living room, master suite, and family room, all feeding into shared or aging flue systems. A proper fireplace inspection checks the damper operation, firebrick condition, hearth clearance, and the path from firebox to flue cap. In Los Altos Hills, we also treat every fireplace as part of a whole-stack system, because a crack in a clay-tile liner behind one fireplace is a problem for the entire chimney.
Camera Inspection
We run a camera down the flue on most Los Altos Hills inspections. It’s the only way to see a cracked clay liner or separated mortar joint that sits behind brick. The camera image gets displayed on your screen as we go, so you see exactly what we see, and you get the photos afterward.
Real Estate Inspection
If you’re buying or selling a home in Los Altos Hills, a Level 2 chimney inspection with camera documentation is what lenders and insurance carriers in Santa Clara County typically want to see. We document everything in writing, and the report is yours. It’s the fastest way to settle a chimney contingency without guessing.
Chimney Inspection Services in Los Altos Hills
Chimney Inspection Services in Los Altos Hills fall into three levels, and the right one depends on your home’s history and construction. A Level 1 inspection is a visual check: accessible portions of the flue, damper, firebox, and exterior stack. It’s what we recommend for a chimney that’s been swept recently and hasn’t changed hands. A Level 2 inspection includes a camera run through the flue and is required when a property is sold, after an earthquake, or if the fireplace has been used heavily with unseasoned wood. A Level 3 inspection involves accessing concealed areas of the chimney, usually when a Level 2 camera run reveals damage that needs closer examination.
Because Los Altos Hills sits entirely within a CAL FIRE Very High Fire Hazard Severity Zone, we recommend a Level 2 camera inspection for any home that hasn’t had one in the last three years. The clay-tile flue liners in 1960s and 1970s estate builds crack quietly, and the camera is the only way to know before burning season starts.
Level 1 Inspection
A Level 1 runs $189 – $289 in Los Altos Hills. We check the accessible sections of the flue, the damper, the firebox, and the exterior masonry. If you’ve burned regularly all season, pair this with a sweep.

Level 2 Inspection
A Level 2 with camera runs $289 – $549, depending on the number of flues and access challenges. Given the sloped foundations and multi-fireplace layouts common in Los Altos Hills estates, most homes here need this level at least once before their next heavy burning season.

Trusted Brands We Service in Los Altos Hills
We install and service DuraFlex liner systems, Olympia Chimney caps and dampers, Famco and Copperfield components, and HeatShield resurfacing, the same materials chimney professionals specify. That matters in Los Altos Hills because the mid-century flue liners in these homes fail in specific ways, and the fix should use components built for the job. Because our crews serve Los Altos Hills regularly, we keep the common parts on hand: correct-size spark arrestor caps, damper assemblies, and liner sections sized for the taller stacks you see on hillside custom builds. When a fireplace in Los Altos Hills needs a part, we’re not waiting a week for a shipment.
Common Chimney Inspection Problems We See in Los Altos Hills Homes
- Cracked clay-tile flue liners. Thermal cycling on sloped hillside foundations causes hairline cracks in the original clay liners of 1960s – 1990s custom estates. A Level 1 glance won’t catch these; a camera will.
- Missing or wrong-size spark arrestors. State law and Santa Clara County fire codes require spark arrestors on all chimneys in the VHFHSZ, yet we regularly find hillside estate chimneys with none at all or one sized for a different cap entirely.
- Uphill-side debris packing. Homes backing onto Rancho San Antonio or the Foothills Park corridor catch acorn caps, bay laurel leaves, and dried oak material inside the chimney cap on the uphill side. It’s a fire hazard separate from creosote and invisible from the driveway.
- Stage-two creosote glazing. The marine fog in Los Altos Hills pushes burning season earlier, and wood that never fully dried glazes the flue faster. Once creosote tars over into stage two, a standard brush won’t remove it.
Pricing for Chimney Inspection in Los Altos Hills, CA
A Level 1 chimney inspection in Los Altos Hills runs $189 – $289. A Level 2 with full camera run costs $289 – $549, depending on how many flues your home has and how accessible the stack is. Homes with three or four fireplaces feeding separate flues will sit at the higher end or slightly above, and that’s honest math, not a markup. We give you the written price before anything starts, and if the camera shows a repair is needed, the quote for that work is separate, in writing, and you decide. Estimates are free. Call (336) 863-3889 and we’ll schedule an inspection, you’ll know the technician’s name before we arrive.

FAQs About Chimney Inspection in Los Altos Hills
Yes. Los Altos Hills sits entirely inside a CAL FIRE-designated Very High Fire Hazard Severity Zone, and Santa Clara County fire codes require a properly sized spark arrestor on every chimney, no exceptions. During our inspections we regularly find large custom estates missing spark arrestors or running caps with the wrong screen size, which is a code violation and a real ignition risk to surrounding oak woodland. Call (336) 863-3889 and we’ll confirm whether your caps are compliant.
At least once a year before burning season, and a Level 2 camera inspection every two to three years. Homes in Los Altos Hills burn earlier and more frequently because of the marine fog, and the older clay-tile liners here fail quietly. If you’re in a home built before 1990 and you haven’t had a camera in the flue in five years, schedule one now. We’ll show you the footage before we recommend anything.
A Level 1 is a visual check of accessible flue sections and runs $189 – $289. A Level 2 adds a full camera run and runs $289 – $549, and it’s what most Los Altos Hills homes need because of aging clay liners and VHFHSZ requirements. A Level 3 is reserved for cases where the camera reveals damage requiring opening portions of the chimney structure. If your home has multiple fireplaces, a property sale, or decades of heavy use, Level 2 is the right starting point. Call (336) 863-3889 and we’ll talk through your home’s specifics.
Your hillside lot backs onto open space, and the ridge winds funnel acorn caps, bay laurel leaves, and dried oak material directly into the uphill-side chimney cap. This is so common on properties near Rancho San Antonio and the Foothills Park corridor that we check for debris packing on every uphill stack during Los Altos Hills inspections. The debris dries out and becomes a secondary fire hazard separate from creosote. A properly fitted spark arrestor cap with the right screen size stops most of it.
No. We recommend only what the camera shows us, and you see the footage before any repair is proposed. If the flue liner is cracked, you’ll see the crack on screen. If the damper doesn’t seat, you’ll see the gap. If nothing is wrong, we’ll tell you the chimney is safe and we’ll leave. That’s the standard Ruben Castellano set when he started Alcott Chimney Sweep, and it hasn’t changed. If a repair is recommended and it fails within a year, the 365-Day Done Right Promise means we come back and make it right, free.
