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 Los Altos, CA
Chimney repair in Los Altos is a different job than sweeping in a dense urban market. Most of the chimneys we work on here serve decorative or occasional-use fireplaces in homes built between the 1920s and 1970s, so the work is less about heavy creosote removal and more about inspection, animal-nest removal, and documenting chimney condition for real estate transactions. Chimney Sweep Berryessa has served Los Altos since 2013. Call (877) 610-3049 if you need a chimney company that can sweep, inspect, repair, and document, all from one team.
Why Los Altos Homes Are Different
Los Altos has a housing stock that runs from 1920s – 1950s cottages near downtown to 1950s – 1970s ranch-style and Eichler-influenced homes on large lots throughout the city. Many of these homes still have their original masonry fireplaces, often with clay tile liners and older dampers that were installed when the house was built. That matters because clay tile liners from that era crack. They crack during the occasional frost, they crack with seismic movement, and they crack simply from decades of heating and cooling cycles.
The climate adds another layer. Mild Mediterranean weather with wet winters and dry summers means Los Altos chimneys see little heavy burning, but they take on moisture. Uncapped flues pull in rain. Cracked crowns let water sit on the smoke shelf. Over time, that moisture degrades mortar joints and rusts dampers. The result is a chimney that looks fine from the outside but fails a level 2 camera inspection when a home goes under contract. We see this pattern regularly in Los Altos real estate transactions, and it’s one of the main reasons buyers and sellers call us before escrow closes.
There’s also the wildlife factor. Roof rats and squirrels are common in Los Altos neighborhoods, and an uncapped chimney is an open door. We regularly pull nests out of flues in the North Los Altos and Country Club areas, often in homes where the fireplace hasn’t been used in years. A chimney cap is the fix, and it’s a repair we recommend more often here than almost anywhere else we work.

Our Main Los Altos Services
Most Los Altos homeowners call us for one of two reasons: they want their chimney swept and inspected, or they know their dryer vent hasn’t been cleaned in years and they’re worried about fire risk. Both services have their own dedicated Los Altos pages, and both are handled by the same team.
Chimney Sweep in Los Altos
A Chimney Sweep in Los Altos starts with an inspection, not a brush. In Los Altos homes with occasional-use fireplaces, the priority is confirming the flue is clear of nests and debris, checking for cracked clay tile liners, and documenting the condition of the damper and firebox. If there’s creosote, we remove it. If there’s a squirrel nest, we remove that too. And if we find a cracked liner or a rusted damper during the sweep, we can quote the repair on the spot because we do both.
Dryer Vent Cleaning in Los Altos
Dryer vents are a fire hazard most homeowners overlook, and Los Altos homes built in the 1950s – 1970s often have long or awkward vent runs that accumulate lint faster than anyone expects. Our Dryer Vent Cleaning in Los Altos service clears the full run from dryer to exterior vent, checks airflow, and flags any venting that doesn’t meet current safety standards. We offer it as a standalone service, which most chimney-only companies in the area don’t.
Chimney Repair in Los Altos
Chimney repair in Los Altos usually follows one of two paths. Either a homeowner calls us because water is staining the ceiling near the fireplace or an animal is in the flue, or a real estate transaction triggers a level 2 inspection that flags cracked clay tile liners, failed crowns, or rusted dampers. Either way, the fix is rarely a sweep. Los Altos homes from the 1920s through the 1970s were built with clay tile flue liners that crack with age, moisture, and seismic movement, and the repairs we do most often here are caps, liner replacement, flashing, and crown work. Chimney Repair is our primary service line, and we stock materials from DuraFlex and HeatShield so we don’t have to refer you to a third party after we diagnose the problem.
Chimney Cap Installation
Signs you need it
You hear animals in the chimney, see water or debris inside the firebox, or you bought a home with an open flue and every rainstorm makes the living room smell damp.
What it costs in Los Altos
A stainless steel or copper cap installation typically runs $260 – $620 in Los Altos depending on flue size and access.
How we do it
We measure the flue, select a cap with the right mesh sizing for local wildlife, and secure it to the crown or flue tile with a mechanical fastener so it stays put in wind and seismic movement.
Chimney Liner Installation
Signs you need it
A camera inspection shows cracked or missing clay tile sections, or the liner is the wrong size for the heating appliance and fails current code.
What it costs in Los Altos
Liner installation in Los Altos typically runs $2,200 – $6,300 depending on the liner type, flue length, and whether the chimney is one or two stories.
How we do it
We camera the flue first, then pull a DuraFlex stainless steel liner through the existing chimney, insulate it where code requires, and reconnect the appliance with a proper tee or direct connection.
Chimney Flashing Repair
Signs you need it
You have water staining on the ceiling near the chimney, peeling paint on the exterior chimney chase, or visible gaps between the roof and masonry.
What it costs in Los Altos
Flashing repair around a Los Altos chimney typically runs $400 – $1,200, more if the roof needs to be cut back to access the full step flashing.
How we do it
We inspect the existing flashing and counterflashing, remove the failed material, install new step flashing and a proper cricket if the chimney is wider than 30 inches, and seal with a high-temperature roofing sealant.
Chimney Crown Repair
Signs you need it
The concrete crown has visible cracks that run deep, water pools on the crown after rain, or a home inspector flagged crown deterioration in a real estate report.
What it costs in Los Altos
Crown repair or replacement in Los Altos typically runs $600 – $1,700 depending on whether we resurface with a flexible sealant or pour a new crown with a proper drip edge.
How we do it
We clean the surface, fill cracks, and resurface with a flexible crown sealant, or we remove the failed crown and pour a new reinforced one with an overhang that sheds water away from the masonry.

How often should I have my Los Altos chimney inspected if I rarely use the fireplace?
The National Fire Protection Association recommends an annual inspection regardless of use. In Los Altos, even an unused chimney needs checking for animal nests, moisture intrusion, and liner cracks that could affect a future home sale.
Do I really need a new liner if my chimney has a few cracks?
Yes, if the cracks are open or the liner is no longer code-compliant for the appliance it serves. Cracked clay tiles can let heat and gases reach combustible framing. We show you the camera footage before recommending a liner, so you can see the condition for yourself.

What Los Altos Customers Say
"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
- Rafael Castillo"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
- Ruben Delgado"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
- Amit Shah
