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 Sweep Across San Anselmo
A standard chimney sweep in San Anselmo typically runs $189 – $289, and the job is booked, not promised for today. We work across the Ross Valley and into the hills, from the flats near San Anselmo Creek up through Sleepy Hollow. Most sweeps in this town take about an hour and a half once our technician is set up, and you get a written price before any tool comes off the truck. Hank Delano runs our crews, and the number to call is (830) 251-4560.
San Anselmo’s tree-heavy valley and overnight fog mean chimneys here behave differently than they do ten miles east in the sun. We know what that does to flue liners, dampers, and fireboxes because we’ve been cleaning and inspecting them in Marin’s older housing stock for years. You’ll get the actual condition of your chimney on camera, not a guess from a visual look-up, and a straight answer on whether it needs work this season or can safely wait.
Why Flint Chimney Sweep Is San Anselmo’s Preferred Chimney Sweep Company
San Anselmo homeowners tend to ask the same questions before booking: what’s the real price, who’s walking through the door, and what happens if the work doesn’t hold up. We answer all three in writing. Every job gets a flat quote before booking, so the invoice matches the number you approved. Our technicians are background-checked and arrive in uniform. And every repair carries the 365-Day Done Right Promise, a written guarantee valid for one full year from the service date. If a covered repair fails, we return at no charge.
We’ve worked on the older bungalows off Sir Francis Drake Boulevard, the larger mid-century homes up toward Winship Park, and the stucco Mediterranean-revival houses around the Seminary area. That local familiarity matters because San Anselmo’s housing stock is not uniform. A 1920s brick firebox and a 1960s prefab flue need different attention, and we know which one we’re walking into before we ring the bell.

Chimney Services in San Anselmo
Chimney Services in San Anselmo start with an honest assessment of what you actually burn, how often, and what your flue looks like on the inside. We don’t sell a sweep because the calendar says so. We sell the service your chimney needs, documented with camera photos you can look at yourself. A standard sweep here runs $189 – $289, and if we find damage that needs repair, you’ll see the photos before you hear a repair quote.
Sweep and Camera Inspection
The sweep removes creosote and soot from the firebox up through the flue. Then we run our camera through the liner to check for cracks, gaps, and moisture intrusion. In San Anselmo’s damp valley, moisture is often the bigger problem than soot, and the camera is what proves it.
Creosote and Soot Removal
Eucalyptus and oak, the woods San Anselmo homeowners burn most, both produce heavy creosote. First-degree creosote is a glazed tar that brushes alone won’t remove. We use mechanical scrapers and rotary heads when needed, then show you the flue before and after on camera.

Chimney Sweep Certified in San Anselmo
Chimney Sweep Certified in San Anselmo means the person on your roof and at your firebox has been trained on the full system, not just the brushing. Our technicians handle level 1 and level 2 inspections, creosote and soot removal, annual sweeps, and fireplace cleaning. A level 2 inspection is what we recommend for any San Anselmo home that hasn’t been looked at in three years or more, especially if you’ve bought the house and don’t know its chimney history.
Level 1 and Level 2 Inspections
A level 1 inspection covers the accessible parts of the chimney and is included with every sweep. A level 2 adds the camera run through the flue interior and checks the crown, flashing, and clearances. In older San Anselmo homes, a level 2 is usually the difference between catching a cracked liner early or finding it after a chimney fire.
Annual Sweep and Fireplace Cleaning
Even a lightly-used fireplace in this valley picks up moisture-driven creosote and debris. An annual sweep for occasional burners costs the same as for heavy users: $189 – $289. The difference is what we find once we’re inside, which is why the camera matters.
Trusted Brands We Service in San Anselmo
We work with professional-grade chimney products, not whatever is left on the shelf. That means liners and repair systems from HeatShield, caps and dampers from Gelco, and chimney components from Olympia Chimney and Famco. When a San Anselmo flue needs relining or a crown needs sealing, we specify the brand by the job. If parts are needed, we carry common replacements for the housing stock in this area, so we’re not waiting a week on a courier from out of state for a damper plate. You’ll see the brand name written on your quote, not just a generic line item.
Common Chimney Sweep Problems We See in San Anselmo Homes
- Glazed creosote re-forming after a wet winter. The flats near San Anselmo Creek hold fog moisture, and a flue that looked clean in October can show first-degree creosote again by February. This is normal for this valley, and it’s why we recommend a post-winter look rather than assuming last fall’s sweep carried you through.
- Blocked caps and screens from oak debris. Big native oaks in Sleepy Hollow and around Winship Park drop a steady supply of leaves and twigs onto caps. A blocked screen backs smoke into the firebox and masks a draft problem that’s been developing for months.
- Cracked crowns on stucco and Mediterranean-revival chimneys. The older stucco chimneys around San Anselmo often have crowns that have been patched, re-patched, and cracked again. Moisture gets in at the top and works its way down through the masonry. A visual check from the ground won’t show it. The camera will.
- Dampers that no longer seat after firebox movement. San Anselmo’s older homes sit on soils that shift seasonally. A damper that used to close tight now hangs open a quarter inch, letting conditioned air out and fog-damp air in. We see this constantly in the 1920s and 1930s bungalows off San Anselmo Avenue.

FAQs About Chimney Sweep in San Anselmo
Once a year if you burn regularly, and at least once every two years if you burn only a handful of weekend fires. San Anselmo’s damp valley air means creosote can re-glaze quickly, so the calendar is less useful than a camera look. If you’re on the annual schedule, the sweep costs $189 – $289. Call (830) 251-4560 and we’ll give you a flat quote before booking.
By the job, always. A standard sweep in San Anselmo runs $189 – $289, and we put that number in writing before we show up. There’s no hourly meter running and no surprise line item at the end. The invoice matches the approved quote, or we’re the ones who explain why not.
The camera shows the inside of the flue liner, the smoke shelf, and the areas behind the damper that you cannot see from the roof or the hearth. In San Anselmo homes, we routinely find cracked clay liners, hidden creosote glazing, and moisture migration that a visual look-up would miss. You get the photos after the inspection, so you can see exactly what we’re talking about before you authorize any repair.
Sometimes, yes. If you burn ten fires a season with dry, seasoned wood and the flue was clean last year, a delay is often fine. The risk in San Anselmo is not just volume, it’s the dampness. A lightly-used chimney in the fog-heavy flats can still build enough first-degree creosote to be a fire concern. The safe move is a camera inspection, not a guess. If the answer is that you can wait, we’ll tell you that plainly.
Yes. We install and service DuraFlex liners, HeatShield resurfacing systems, Gelco caps and dampers, and Olympia Chimney products. The brand we recommend depends on your chimney’s condition and construction, not on what we happen to have in the truck. You’ll see the brand name written on your quote.
San Anselmo sits in a narrow, tree-heavy valley where overnight marine fog off Mt. Tam’s slopes keeps flues and fireboxes damp well into spring. That means even lightly-used chimneys here build creosote and spalling mortar faster than in sun-exposed East Bay towns. We were called to a 1920s bungalow off San Anselmo Avenue where the homeowner burned mostly eucalyptus and oak on weekends. After a Level 2 inspection with our camera, we found first-degree creosote coating the flue liner and a damper that no longer seated because the firebox had cracked and let moisture migrate. We swept the flue, scraped and re-pointed the firebox, pulled and re-fitted the damper, and sent a photo report showing the chimney crown and flashing condition. The homeowner later used our Chimney Repair - San Anselmo service for ongoing maintenance. That’s how we work in San Anselmo: document what we find, show you the photos, and put every repair in writing with a one-year guarantee behind it.
If your chimney in San Anselmo needs a sweep, an inspection, or an honest answer about whether you can wait, call (830) 251-4560. Hank and our crew will give you a flat price before booking, and you’ll know exactly what you’re getting before we ring the doorbell.
