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.

A chimney inspection in Los Altos runs $189 – $389 for most homes, depending on whether it’s a Level 1 visual check or a Level 2 camera inspection.

Flint Chimney Sweep runs on a simple rule: the price you approve before we start is the price on the invoice. No add-ons after the fact, no “while we’re up there” upsells. That’s the Garrison Standard, and it applies on every inspection in Los Altos, from the 94022 blocks near downtown to the 94024 hills up toward Rancho San Antonio.
Why Flint Chimney Sweep Is Los Altos’s Preferred Chimney Inspection Company
Los Altos homeowners call us because straight answers are hard to come by in this trade. We’ve been part of the Garrison Partners family since 2002, and every inspection we perform in Los Altos carries the same documented commitment: a written price before any work begins, a background-checked uniformed technician on site, and a full-year written guarantee on any repair we recommend and you approve.
Our Los Altos customers tell us the same thing: another company said they needed a liner, or a rebuild, or a $4,000 repair, and nobody could show them photographic proof. We do not recommend a repair without a camera image you can look at yourself. If the flue is fine, we say so. If it can wait a season, we say that too. That plain-spoken approach is why homeowners on Grant Road, Miramonte Avenue, and throughout Los Altos and Los Altos Hills keep our number on hand.
Dispatch for Los Altos is coordinated from our San Francisco Bay Area office, and our crews know the housing stock here. Ranch houses built in the 1950s and 1960s dominate the area, and we know what those chimneys do after sixty years of seismic settling and clay soil movement in the Adobe Creek and Permanente Creek drainages.
Chimney Leak in Los Altos
A chimney leak in Los Altos rarely announces itself as a chimney problem. What homeowners see is a brown stain on the living room ceiling after a week of rain, usually within a few feet of the fireplace. That stain often gets blamed on the roof. But in Los Altos, where the sun-and-rain cycle beats on chimney crowns year after year, the leak is usually crown cracking or flashing failure where the chimney meets the roofline.
When we inspect a leaking chimney in Los Altos, we start at the top: crown condition, mortar joints, flashing, and the cap. Then we run the camera down the flue to see if water has reached the inside. Water that gets past the crown migrates through the masonry, dissolves mortar, and rusts dampers shut. Left alone, that water damage ruins the flue liner and eventually shows up in the smoke chamber. A chimney leak inspection in Los Altos runs $249 – $389 when combined with a Level 2 camera run. If the crown needs rebuilding, a typical crown repair here runs $450 – $850 depending on the crown material and access.
Crown and flashing failure
Most Los Altos chimney crowns are poured concrete from the original build, and after fifty or sixty years the concrete is spalled, cracked, or gone. Water runs into the crack, freezes or dries, and widens it. The flashing, which is just metal bent to seal the gap between the chimney and the shingles, eventually lifts and lets water run straight down into the ceiling framing.
What the camera shows
A leak inspection is not complete until we run the camera inside the flue. Water marks on the flue tile, rust stains on the damper, eroded mortar in the smoke chamber: that tells us how long the leak has been running and what got damaged. We hand you the photo report with the affected areas labeled so you can see exactly what we’re seeing.
Chimney Camera Inspection in Los Altos
A chimney camera inspection in Los Altos is the Level 2 inspection: a full-length, real-time video scan of the entire flue from the firebox up to the cap, looking for cracks, gaps, spalling tile, creosote buildup, and animal debris. This is the inspection homeowners need after a chimney fire, after an earthquake, before buying a house, or when they’ve lived in the home for years without ever looking inside the flue.
In Los Altos, where most chimneys date to the housing boom between 1945 and 1975, the camera frequently reveals things a flashlight never would. Flue tiles crack along mortar joints as the house settles. The shaking from earthquakes, even moderate ones, opens hairline gaps between tile sections. Those gaps let heat and combustion gases reach the wood framing around the chimney chase, which is how chimney fires spread into house fires.
A Level 2 chimney camera inspection in Los Altos runs $349 – $489 for a single flue, and it includes the written photo report. If you’re buying or selling a house anywhere in Los Altos, a camera inspection is the only way to satisfy a real estate inspection requirement with confidence. Sellers get a clean report to show the buyer. Buyers get to see the actual condition instead of taking someone’s word. Either way, call us at (830) 251-4560 and we’ll schedule it.
Photo report included
Every camera inspection comes with labeled stills pulled from the video: a tile crack, a creosote band, a nest in the smoke chamber. You see what we see. If we recommend a repair, the photo is in the report, so you can take your time deciding, or show it to another company and ask them to compete honestly.
Buying or selling in Los Altos
Los Altos real estate moves fast, and inspections are part of nearly every escrow. We are familiar with the Level 2 requirement from the Los Altos Hills and Los Altos school district areas down to the 94022 ZIP code. Our reports are accepted by local buyers, sellers, and agents because they are specific, dated, and unambiguously photographic.
Trusted Brands We Service in Los Altos
When a Los Altos inspection turns up a liner that needs work, we use materials from brands built for the job. HeatShield is our standard for flue liner repair because it seals and resurfaces cracked tile without a full teardown. Gelco caps and chase covers handle the rain and sun exposure Los Altos chimneys live in, and Olympia Chimney components give us factory-built options for flashing and termination. We keep common parts in local stock and can order Los Altos-specific sizing quickly, so a repair usually moves to scheduling within days of the inspection, not weeks.
Common Chimney Inspection Problems We See in Los Altos Homes
- Hairline flue tile gaps from settling. Los Altos sits on clay soil that swells and contracts with the irrigation cycle, and the 1940s – 1970s ranch houses here have settled through decades of it. Those hairline gaps between flue tiles are the most common finding on our camera runs, and they are invisible without one.
- Cracked crowns from the wet-dry cycle. A Los Altos chimney crown gets baked by summer sun and soaked by winter rain, year after year. Concrete spalls, cracks, and lets water into the masonry. The first symptom is usually a ceiling stain, not a chimney problem.
- Damaged or missing caps and spark arrestors. Squirrels, birds, and raccoons get into uncapped chimneys. We regularly pull nests out of Los Altos smoke chambers, and the debris cuts the draft, which pushes carbon monoxide back into the house when the fireplace burns.
- Thick creosote from under-used fireplaces. Fireplaces burned twice a year for a decade might sound safe. They are not. First-degree creosote bakes into second-degree, then third, and the flue narrows. We see this in Los Altos homes where the fireplace is decorative except for holidays.

FAQs About Chimney Inspection in Los Altos
Most Los Altos homeowners do not need a full Level 2 camera inspection every year. What you need is a Level 1 visual check when we’re already at the house for a sweep, and a camera inspection every few years or any time you notice a change: a stain, a smell, or a fireplace that isn’t drafting the way it used to. The annual sweep is the real necessity. Creosote builds even with light use. Call (830) 251-4560 to talk through your actual burn habits and we’ll tell you straight what you need.
The camera reaches the full length of the flue, including the smoke chamber and chimney crown area from the inside. A flashlight lets us see the first few feet of flue tile above the damper. It misses cracks in the upper third of the flue, hairline gaps between tile sections, mortar erosion deep in the smoke chamber, and blockage behind the damper housing. It’s the difference between looking through the front window and walking the whole house. Every camera inspection in Los Altos includes the photo report so you are looking at the same images we are.
If the stain is within three or four feet of the fireplace, and especially if it follows the line of the chimney chase, it’s more likely the chimney flashing or crown than the roof. Roof leaks tend to show at valley lines or low spots. Crown and flashing leaks follow the chimney. We can confirm it with a leak-specific inspection that starts at the top of the chimney and works down. Call (830) 251-4560 and tell us where the stain is; we’ll tell you over the phone whether it sounds like a chimney issue.
You can, but we will not recommend it. In Los Altos, where flue tile cracks from settling are common, sweeping without looking is how problems go unnoticed for another decade. The inspection is what tells you whether the sweep was enough or whether you have a gap in the flue that heat can reach the framing through. The report is included in the Level 2 price and the Level 1 add-on price, so you are not paying separately for it. If we find nothing wrong, we say so and you have the report as proof.
Third-degree creosote, the hardened glaze that looks like tar, cannot be brushed out with a standard sweep. It requires chemical treatment or mechanical removal with rotary tools, and it often means the flue liner has already been compromised. The good news: third-degree is rare in Los Altos homes that burn dry wood in moderate amounts. When we do find it, the camera images tell us whether the liner underneath is still sound. We will show you the photos and give you a flat price for the right fix. Call (830) 251-4560 and we’ll inspect it properly.
