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 San Anselmo
A chimney inspection in San Anselmo typically runs $189 – $389 depending on the level of inspection (Level 1, Level 2, or Level 3), and most inspections take 45 to 90 minutes. You’ll get a camera report with photos before you pay a dollar more than the written price you approved. That’s how Hank Delano runs Flint Chimney Sweep, and it’s why homeowners in Sleepy Hollow, Gerstle Park, and the flats around San Anselmo Avenue call us first when a chimney starts acting damp or smells wrong. If you’re noticing a musty odor from the firebox, staining on the ceiling near the chimney, or you simply can’t remember the last time anyone looked inside the flue, call (830) 251-4560. We’ll give you a straight answer on what needs doing now and what can wait.
Why Flint Chimney Sweep Is San Anselmo’s Preferred Chimney Inspection Company
We’ve been inspecting chimneys in San Anselmo long enough to know the pre-war bungalows off San Anselmo Avenue and the slope-side homes above Sir Francis Drake Boulevard have their own way of failing. Moisture gets into the crown and flashing first. Creosote builds in flues that don’t see a brush for years. And the clay-tile liners in 1920s and 1930s construction spall and crack in ways that newer stainless liners don’t. Our inspectors are trained to read those specific patterns, not just run a camera for the sake of it.
Every Flint Chimney Sweep technician who arrives in San Anselmo is background-checked and uniformed, so you know exactly who’s walking through your door. The phone is answered by a live person 24/7, which matters when you find water in the firebox on a wet Ross Valley night. And we put everything in writing before any tool comes off the truck: the scope, the price, and the 365-Day Done Right Promise. If a covered repair fails within a year, we come back at no charge. No argument, no second invoice.
Chimney Flue Inspection in San Anselmo
A chimney flue inspection in San Anselmo means running a camera up the liner to check for creosote buildup, cracks, spalling, and separation in the mortar joints. In this part of Marin County, the damp that rolls up the Ross Valley through Gerstle Park and Sleepy Hollow gets into the flue from the top down, so we spend as much time on the crown and cap as we do on the liner itself. A flue inspection alone typically runs $149 – $249, and it’s the right call when you smell damp smoke, notice water staining near the chimney, or find small pieces of tile or brick in the firebox.
What the Camera Actually Shows
Our inspection includes a photo report of the inside of your flue liner, shot in real time. You’ll see exactly what we see: the degree of creosote, any cracked tiles, any separation where water could be getting behind the liner. Nothing gets recommended without visual evidence. If we tell you a flue needs relining, you’ll be looking at the photo that proves it while we explain it.
When the Flue Can Wait
First-degree creosote, a hairline crack in a crown that hasn’t let water through yet, or a damper that operates but sticks slightly. These are the things we write down, photograph, and tell you to watch. We won’t schedule work that doesn’t need scheduling. But if the camera shows second or third-degree creosote, or a liner that’s separated enough to let flue gases into the wall cavity, we’ll tell you that plainly too.
Chimney Fire in San Anselmo
A chimney fire in San Anselmo almost never starts the way people expect. It starts quietly, usually after a season or two of burning wood on top of second-degree creosote, and it announces itself as a loud roar or a sudden popping from the flue, sometimes with flames visible at the top of the chimney. Because Ross Valley homes tend to have shorter, steeper rooflines and chimneys close to the ridge, chimney fires here can spread to the roof faster than in flat, open neighborhoods. The inspection to catch this before it happens costs far less than the repair after: a Level 2 inspection in San Anselmo runs $249 – $389.
What We Check After a Chimney Fire
If you’ve had a chimney fire in San Anselmo, even a small one, our Chimney Inspection team checks the flue liner for pitting, cracking, or separation from the masonry. A clay-tile liner that survived fifty years of normal burning can fail after one chimney fire. The crown, cap, and attic chase all get checked for heat damage. You’ll get a written report on what’s safe to use and what needs repair before another fire goes in the box.
Preventing the Next One
The fire district that covers San Anselmo has responded to chimney fires in homes where the owner was certain the chimney had been cleaned recently. The issue is usually what’s left after a sweep: glazed third-degree creosote that a brush can’t remove. That’s where a camera inspection before the burning season catches what a visual check misses. Chimney cleaning work in San Anselmo isn’t optional overhead; it’s what keeps the flue from turning into a vertical firebox.
Trusted Brands We Service in San Anselmo
When a San Anselmo chimney needs parts, we install components from manufacturers that stand behind their product the same way we stand behind our work. That means DuraFlex for relining when a flue liner has failed, HeatShield for repairing damaged clay-tile flues without tearing out the chimney, and Olympia Chimney caps and dampers for the top end. Because we stock these locally and know the San Anselmo housing stock, we can usually turn around a liner or crown repair in days, not weeks. If a manufacturer ever discontinues a part we specified, we re-spec the job before we re-schedule it, and the written price you approved stays the price you pay unless you sign a change order.
Common Chimney Inspection Problems We See in San Anselmo Homes
- Failed flashing at the roof line. San Anselmo’s winter rain runs down the slope of the roof and sits at the base of the chimney, so the flashing joint takes more water than it does in drier parts of Marin. Once the seal breaks, water follows the mortar line down into the smoke chamber and firebox.
- Spalled crowns on pre-war chimneys. The concrete crowns on 1920s and 1930s San Anselmo homes were poured thin and often without proper overhang. After decades of Ross Valley damp-and-dry cycles, they crack and let water into the masonry. Repointing is often enough; full crown replacement is rare.
- Clay-tile liner separation. In older San Anselmo homes, the clay tiles inside the flue separate over time from heat cycling and house settlement. The gap becomes a place where heat and flue gases leak into the wall. A camera inspection shows the separation directly.
- Moisture-driven creosote hardening. Wood burned in damp air produces a stickier, heavier creosote. In San Anselmo, where fog and winter damp sit in the Ross Valley, that creosote hardens into a glaze that a standard brush won’t remove. The camera tells us the degree so we know whether a sweep alone will do it or a chemical treatment is needed.

FAQs About Chimney Inspection in San Anselmo
Once a year, even if you only burn a few fires a season. The reason in San Anselmo is moisture: the damp air that sits in the Ross Valley finds its way into the crown, the flashing, and the liner whether or not there’s a fire. A quick Level 1 inspection catches water damage before it becomes a leaky wall or a spalled crown. If you’ve burned less than a cord of wood since the last sweep, you can usually skip the sweep and just get the inspection. Call (830) 251-4560 to talk through your burn habits with Hank and his team.
We open the damper, check the firebox, run a camera up the flue liner, inspect the smoke chamber, then go up on the roof and look at the crown, cap, and flashing. Every step is photographed. You get a written report with the photos, a list of what’s fine, what can wait, and what needs work now, with prices attached. You never have to guess what the camera saw or take our word for it. Call (830) 251-4560 to schedule.
No. An inspection and a sweep are separate services, and we quote them separately. If the camera shows first-degree creosote and you haven’t burned much since last year, we’ll tell you a sweep isn’t necessary yet and show you the photo so you know why. The inspection is $189 – $389 depending on level. A standard sweep in San Anselmo runs $189 – $289. You’ll approve a written price for each before anything starts.
First-degree is a soft, dusty film; it brushes off easily. Second-degree is a thicker, flakier layer that burns hotter and faster. Third-degree is a hardened glaze that a brush alone won’t remove and that burns like fuel. The degree matters because it tells us whether a sweep is enough or whether you need chemical treatment. In San Anselmo’s damp air, creosote hardens faster than it does in drier climates, so a camera inspection that measures the degree is the only honest way to know what you’re dealing with. Call (830) 251-4560 for an inspection and a straight answer.
When the camera shows first-degree creosote, no liner cracks or separation, a crown with only hairline cracking that hasn’t let water through, and flashing that’s still sealed. If that’s what your report says, you can wait until next season, and we’ll put that in writing. What you shouldn’t put off is second or third-degree creosote, a separated clay liner, or water actively entering around the flashing. Those are the conditions that lead to chimney fires or structural damage, and they only get more expensive with time. Call (830) 251-4560 and we’ll show you the photos either way.
We were at a 1920s bungalow off San Anselmo Avenue near the Hub, where the homeowner had never had the flue looked at and only called because the firebox smelled damp. Our tech pulled the damper, ran a camera up the flue liner, and found second-degree creosote in the upper section plus spalling on the chimney crown, with water tracking down past the flashing into the smoke chamber. We photographed every stage and gave the homeowner a straight answer: the creosote could be brushed and the crown repointed before the next wet season, but nothing there was a today-or-else emergency. That’s what a real inspection in San Anselmo looks like.
