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 Tiburon
A proper chimney sweep in Tiburon runs between $220 and $360 for a standard masonry or prefab fireplace with one flue, and we put that price in writing before a single tool comes off the truck. Marine air and hillside lots here create venting and corrosion issues you won’t find in San Rafael or Corte Madera, so the work has to account for local conditions. Hank Delano runs our crews on this side of the bay, and every appointment starts with a flat quote, not a guess. Call (830) 251-4560 and you’ll get a real person, a straight price, and a sweep that leaves you with a photo report showing exactly what was cleaned and what the camera found.
Why Flint Chimney Sweep Is Tiburon’s Preferred Chimney Sweep Company
We’ve worked on enough Tiburon chimneys to know the difference between a house on Belvedere Island and one up on a ridge off Paradise Drive. The draft behaves differently. The caps corrode faster. Homeowners here get burned by two things: companies that quote low over the phone and re-price at the door, and crews that rush a brush through the flue with no camera evidence of what they actually did. Neither happens with us.
Our Chimney Sweep techs arrive in uniform, background-checked, and with a written scope of work the customer signed off on before we arrived. Every job gets a camera inspection and photo report, included. If we find second-degree creosote in the smoke chamber or hairline cracks in the liner, you see the footage yourself before we recommend anything. That’s the Garrison Standard: nothing recommended without proof, nothing billed without agreement.
Response time to Tiburon is typically two to four business days for a routine sweep, and our dispatch runs through the San Francisco Bay Area office, not a call center in another state. Reviews from Tiburon homeowners consistently point to the same things: we show up when we say we will, the price doesn’t move, and the written guarantee actually means something. One year, in writing, on every repair we do.
Gas Fireplace Cleaning in Tiburon
Gas Fireplace Cleaning for Tiburon homes is not just about the log set. A gas fireplace still produces soot, still attracts dust and pet hair into the burner ports, and still vents combustion byproducts through a chimney or direct vent that can clog or corrode under salt-laden air. The glass haze, the lazy yellow flame, the faint smell when the unit kicks on – those all point to the same thing: the burner and vent need attention. A standard gas fireplace cleaning in Tiburon runs $180 to $260, including disassembly of the log set, cleaning of the burner and pilot assembly, glass cleaning, and a visual check of the vent termination outside the house.
Burner and Pilot Service
We pull the logs, clean the burner ports with compressed air and proper brushes, and re-seat the ember bed so the flame pattern returns to normal. Sooted or partially blocked burner ports cause uneven heating that can warp the logs over time. The pilot assembly gets cleaned and the thermopile reading is checked against the manufacturer’s spec, because a weak thermopile is the most common reason a Tiburon gas fireplace won’t stay lit on a damp night.
Vent and Termination Check
Homes closer to the Tiburon shoreline accumulate salt film on vent terminations much faster than inland properties. We clean the termination, confirm the vent run is intact, and make sure the draw is appropriate. Direct-vent gas fireplaces in hillside houses can backdraft on windy days if the termination is unprotected or the run has too many elbows. We flag that in the photo report.
Chimney Maintenance in Tiburon
Chimney Maintenance work in Tiburon covers what a basic sweep does not: the cap, the crown, the flashing, the damper assembly, and the masonry joint lines that marine moisture works on year-round. Most of what we repair on Tiburon chimneys is not creosote. It’s rusted steel and spalled mortar. A maintenance visit typically runs $150 to $250 on top of a sweep, depending on what actually needs to be serviced, and includes tightening or replacing the damper hardware, sealing minor crown hairline cracks with an appropriate sealant, and lubricating the top-seal damper if one is installed.
Cap and Flashing Inspection
The chimney cap takes the worst of the marine layer in Tiburon. Galvanized caps show rust spotting within three to five years on the bay-facing side of the ridge, while stainless caps last much longer. We check the cap’s screen for animal entry, verify the flashing is still sealed against the roofline, and note any rust that’s advancing toward failure. Replacing a standard cap here runs $180 to $320 installed, depending on flue diameter and material.
Crown and Masonry Seal
Spalling on the crown – the concrete slab that caps the masonry – is the single most common water intrusion point we find in Tiburon chimneys. Hairline cracks let water in, the freeze-thaw cycle widens them, and within a few seasons the crown starts crumbling into the flue. We seal minor cracks with a flexible crown sealer and flag anything beyond surface repair. That’s maintenance that buys years, not a repair that costs thousands.
Trusted Brands We Service in Tiburon
We stock common components from HeatShield, Gelco, and Olympia Chimney so Tiburon customers aren’t waiting on freight for a straightforward cap replacement or top-seal damper. HeatShield resurfacing is what we spec for a liner with early joint failure but otherwise sound masonry; it restores the flue walls without a full teardown. Gelco chimney caps and Olympia Chimney dampers are our default for replacements because the marine environment punishes cheap steel, and we’d rather install something that survives the fog line. If you have an existing DuraFlex liner, we service that too. Same standard: written quote before work, camera report when we’re done.
Common Chimney Sweep Problems We See in Tiburon Homes
- Rusted caps and corroded flashing from marine air. Homes in the 94920 ZIP, especially those on the western ridge faces, show accelerated oxidation on galvanized steel components compared to Mill Valley or Larkspur at the same age. We replace more caps in Tiburon per chimney serviced than any other Bay Area community we cover.
- Hillside draft reversal on windy days. Chimneys on lots off Paradise Drive and up toward the open space can backdraft when a strong onshore wind hits the flue at the wrong angle. The fix is sometimes a taller cap, sometimes a top-seal damper, sometimes a flue extension. We diagnose it with a smoke test, not a guess.
- Second-degree creosote hiding in smoke chambers. Even light burners in Tiburon get glazed creosote deposits because the marine air brings humidity into the flue system, and creosote plus humidity forms a harder, more flammable compound. A brush-only sweep misses it. Our camera inspection doesn’t.
- Raccoon and bird nesting in unused flues. Houses that sit quiet through the summer months – common in Tiburon when people travel – become nesting sites. The flue gets blocked, the smell gets into the house, and the cleanup is worse than it would have been if the cap screen had been intact. We remove the nest, sweep the flue, and repair the cap screen on the same visit.

FAQs About Chimney Sweep in Tiburon
Once a year, not because of heavy use but because of marine moisture and animal activity. Tiburon’s humidity accelerates creosote hardening in the flue even with light burning, and an unused flue is an open invitation for nesting. The NFPA 211 standard – the same code our inspections follow – says annual inspection regardless of burn volume. You can skip a year if you never burn and the cap screen is intact, but skipping two years is where most of our worst Tiburon discoveries come from. Call (830) 251-4560 and we’ll tell you plainly if your chimney can wait another season.
A proper sweep includes brushing the flue, removing creosote and soot from the smoke chamber, cleaning the firebox, checking the damper operation, and a visual inspection of the cap and flashing – that’s the $220 to $360 base. The camera inspection is a separate service. At Flint, the camera report is included in the sweep price, not billed as a line item. That’s the distinction. Other companies in Tiburon charge $150 to $250 extra for a camera run. We run it on every chimney because without footage of the liner and smoke chamber, neither you nor we know what condition the system is actually in. The photo report goes to your email before we leave the driveway.
It depends on what the camera shows, and that’s not a dodge – it’s the honest answer. If the report shows first-degree creosote and an intact liner, you can wait. If it shows second-degree creosote glazed on the smoke chamber walls or hairline cracks in the flue liner, you’re running a chimney fire or carbon monoxide risk that should not wait for next season. On that hillside house near Tiburon Boulevard, the photo report showed the carbon monoxide risk clearly enough that the homeowner decided not to light a fire until the damper was freed and the smoke chamber cleaned. We’ll tell you straight: here’s what we found, here’s what it means, here’s what can wait and what cannot. The call is free.
Yes, though gas fireplaces need a different service – cleaning the burner and pilot assembly, the glass, the log set, and checking the vent run and termination. That’s $180 to $260 in Tiburon and should be done every one to two years. Gas units don’t produce creosote, but they do produce soot and combustion byproducts that clog burner ports and haze the glass. The venting still needs to be clear and the termination free of salt film and debris, especially on the bay-facing side of the peninsula where marine air deposits build up faster. A blocked direct vent on a hillside house can send carbon monoxide back into the living space instead of out the wall. That’s a sweep, just a different kind.
A Level 1 inspection covers the accessible portions of the chimney and is the right call for a routine annual check when nothing has changed – same fuel, same usage, no problems. A Level 2 inspection adds camera footage of the full flue and is required when you’re buying or selling the house, changing fuel type, or after a chimney fire or building movement. Hillside lots in Tiburon shift more than flatland lots, and a Level 2 on an older hillside home often catches liner cracks that a Level 1 cannot see. A Level 3 is invasive – partial teardown to access hidden areas – and is only called for when a Level 2 reveals serious structural concerns. Most Tiburon homeowners need a Level 1 with camera footage included, which is what our standard sweep covers.
