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.

AfterFast, Reliable Chimney Inspection Across Berkeley
A chimney inspection in Berkeley typically runs $189 to $389 depending on the level, and most appointments take under an hour once we’re on the roof. We work across the flats, the Elmwood, and up into the Berkeley Hills every week, so our crews know the difference between a 1920s brown-shingle stack and a midcentury cinderblock chase before the ladder goes up. If you need a Chimney Inspection you can book with confidence, call (336) 863-3889 and a live person will answer. No callback queue, no voicemail tree.
Why Alcott Chimney Sweep Is Berkeley’s Preferred Chimney Inspection Company
Ruben Castellano started Alcott Chimney Sweep in 2002 because he kept running into the same problem: homeowners couldn’t verify who was actually coming to their door. In Berkeley, where many residents live in attached flats or hillside homes with only one roof access point, that concern gets sharper. You can’t see the person on your roof from your kitchen. So we built a company around proof. Every technician is background-checked and identity-verified under the Threshold Standard. You get the technician’s name and photo before the visit, and they show a photo ID badge at your door. Every time, no exceptions. That’s not an add-on. That’s how it works.
We also put pricing in writing before any work starts. A chimney inspection in Berkeley doesn’t turn into a surprise liner replacement quote you never asked for. You see the numbers first, approve them, and only then do we start. If we find damage, you get our camera footage, our written report, and a recommendation that respects your budget. Sometimes that means telling a homeowner in the Berkeley Hills their flue can wait another season. We say that when it’s true.
Our crews serve the entire city, from the marina up Grizzly Peak, and we carry the brands Berkeley chimney professionals actually specify: HeatShield for resurfacing cracked liners, DuraFlex for full relines, and Famco caps and arrestors. You won’t get box-store substitutes installed on your stack.
Chimney Flue Inspection in Berkeley
A Chimney Flue Inspection in Berkeley is our most-requested service for good reason: most of the city’s chimneys are original to homes built between 1900 and 1930. That means clay tile liners, lime mortar, and decades of wet winters working against them. A flue inspection here starts at $189 for a Level 1 look down the stack, and moves to $289 to $389 when we run a camera through the flue or open an access panel. We’re checking the liner first, because a cracked liner in Berkeley isn’t rare. It’s expected.
What the camera sees
Our camera flue inspection runs the full length of the liner and records everything. In Berkeley’s brown-shingles, we regularly find vertical cracks at mortar joints where the original clay tile separated. Those cracks let heat, gas, and embers reach the brickwork behind the liner, and in the Very High Fire Hazard Severity Zone that’s a problem you don’t sit on. The footage is yours to keep, and we review it with you on site.
When a real estate deal is on the line
Berkeley real estate transactions move fast, and a chimney inspection contingency is standard on older homes. We photograph the firebox, the damper, the spark arrestor, and the crown. Then we produce a written report with line items a buyer’s agent can actually use. If the flue is shared with an adjacent unit, which happens constantly in Berkeley’s attached Edwardian flats, we document the shared stack condition and whether both units are drafting correctly.
All of this is covered by our 365-Day Done Right Promise. If a repair we make fails within a year, we come back and fix it free. Written guarantee, included on every repair we perform.
Chimney Fire in Berkeley
A Chimney Fire in Berkeley is the scenario every hills resident thinks about, and for a reason that still shapes this city: the 1991 Tunnel Fire burned straight into the Berkeley Hills and killed 25 people. A chimney inspection here is, in part, an ember-escape audit. Creosote that has glazed into a hard tar layer can ignite inside your flue, and if the spark arrestor is rusted through, burning embers can leave the stack entirely. We don’t inspect chimneys in Berkeley the way we might in flatland Oakland or Emeryville. Here, the arrestor screen is code, not a suggestion.
Third-degree creosote and Spare the Air
Berkeley’s mild, wet winters seem like they’d mean light burning. The opposite happens. Homeowners burn on the few days Spare the Air allows, and they burn low and smoldering to stretch a fire through the evening. Low smoldering fires create the worst kind of creosote: third-degree glaze, the tar-like coat a brush can’t remove. During a flue inspection we identify which degree of creosote you’re dealing with and tell you plainly whether it’s a sweep or a chemical treatment.
What the 1991 fire changed
Since the Tunnel Fire, Berkeley’s hills have lived under stricter fire-safety rules than the cities below them. California code requires spark arrestors on all chimney flues in Very High Fire Hazard Severity Zones, and the entire Berkeley Hills sits inside one. A galvanized arrestor screen from the 1970s, rusted through at the mesh, is a violation. We check it on every inspection and photograph it for your records. Insurance renewals in the hills routinely ask for this documentation.
Trusted Brands We Service in Berkeley
Berkeley homeowners with older homes don’t want experimental products installed on their flues, and neither do we. Alcott installs and services the same trade brands chimney professionals specify: HeatShield for resurfacing a cracked clay liner without a full rebuild, DuraFlex for a complete stainless reline when the liner has failed, and Famco caps and spark arrestors that meet California’s fire-zone requirements. We stock common parts for these systems so a Berkeley inspection that turns up a failed arrestor can often be corrected the same visit, not scheduled for a second trip.
Common Chimney Inspection Problems We See in Berkeley Homes
- Shared stacks with cross-contamination. Berkeley’s Edwardian flats and brown-shingle duplexes often vent two or three appliances into one masonry chimney. When the upper flue’s clay liner cracks, the lower unit’s exhaust can pull into the upper firebox instead of venting out. We check for this on every multi-unit inspection.
- Rusted-through spark arrestors. Original galvanized screens in hills chimneys have often rusted to a web of holes after 50 years of fog and marine air. That’s a direct code violation in the Very High Fire Hazard Severity Zone, and we photograph and document the condition for your insurance file.
- Spalling crowns from wet winters. Berkeley’s wet Mediterranean winters push moisture into aging masonry, and a cracked or spalled crown lets rain run straight down the flue. The mortar erodes further every season. By the time you see water stains on the ceiling, the damage is years old.
- Third-degree creosote glaze. Because burning is compressed into fewer days by Spare the Air alerts, Berkeley homeowners often build up hard tar creosote faster than they expect. A brush can’t remove it, but an inspection identifies it before it becomes a chimney fire.
Pricing for Chimney Inspection in Berkeley, CA
Here’s what a Chimney Inspection in Berkeley actually costs. A Level 1 visual check runs $189 to $229. A Level 2 camera inspection, the one we recommend for any home sale, real estate transaction, or after a chimney fire, runs $289 to $389. A Level 3 inspection, which involves opening a section of the chimney to access concealed damage, is quoted after we see the Level 2 footage. The age of your stack, whether it’s shared with a neighbor, and whether the roof access is steep all affect the final number. You’ll get the price in writing before any work begins, and the estimate is free. Call (336) 863-3889 to book an inspection.

FAQs About Chimney Inspection in Berkeley
Yes. The Berkeley Hills sit inside a California-designated Very High Fire Hazard Severity Zone, and state code requires a compliant spark arrestor on every chimney flue. A rusted or missing arrestor is a code violation, and it’s one of the first things we document during any inspection here. Call (336) 863-3889 if you want yours checked, and we’ll photograph the condition for your records.
The biggest risk is cross-contamination. When the upper unit’s clay liner cracks at a mortar joint, the lower unit’s appliance exhaust can pull into the upper firebox instead of venting out the stack. That’s carbon monoxide entering a neighbor’s living space, and it’s why shared-stack inspections are more involved in Berkeley than a single-family flue check. We run a camera through both flues to verify each is drafting independently.
Even a seldom-used chimney should be inspected every two years, and annually if you live in the hills. Berkeley’s wet winters erode mortar year-round, regardless of how often you light a fire. Birds, raccoons, and debris also build up in unused stacks. A Level 1 inspection catches these issues for under $230 before they become structural problems. Call us for that exact quote.
Yes, and we’ll show you on camera. First-degree creosote is a dusty soot that a standard sweep handles. Third-degree creosote is a hard, tar-like glaze that has baked onto the flue walls, usually from low smoldering fires. A brush won’t remove it. When we find third-degree glaze, we talk through HeatShield resurfacing or chemical treatment options and give you the price in writing before any work starts.
Because Berkeley’s hills carry the memory of the Tunnel Fire, insurers and buyers both want proof that a chimney is safe. A written inspection report with photos of the liner, arrestor, and crown gives an underwriter something concrete to file. For a real estate sale, it answers the buyer’s contingency with documentation instead of a handshake. We write reports for both uses, and every repair we recommend is backed by our 365-Day Done Right Promise.
If you need a Chimney Inspection for a Berkeley Hills stack, a shared Edwardian flue, or a brown-shingle with original clay tile, call (336) 863-3889. A live person answers, you’ll get the technician’s name and photo before we arrive, and the price is in writing before any work begins.
