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.

Why Flint Chimney Sweep Is Kentfield’s Preferred Chimney Sweep Company
We’ve been at this since 2002 as part of the Garrison Partners family, and the thing that sets us apart in Kentfield is simple: we put the price, the scope, and the guarantee in writing before a single tool comes off the truck. That’s The Garrison Standard, and every Flint crew member follows it. No vague phone estimates that inflate at the door. No work you didn’t approve. If a repair isn’t done right, our 365-Day Done Right Promise covers it for a full year, and we return at no charge.
Kentfield homeowners deal with specific conditions: mature oaks and bays shedding into caps and flues, wet winters testing crowns and flashing, and fireplaces that see occasional use but still build creosote. Our technicians are background-checked and uniformed, and a live person answers our phone around the clock. When you call (830) 251-4560, you get a real answer, not a voicemail tree.
Fireplace Cleaning in Kentfield
Fireplace cleaning in Kentfield is rarely just about brushing soot off the firebox walls. Our first sentence here tells you what the job actually involves: a full sweep of the flue and smoke chamber, clearing of the cap and crown, and a camera check of the liner so you know exactly what’s happening above the damper. Most Kentfield homes with an open fireplace need this once a year, especially if you burn wood more than a couple of fires per month. A standard Kentfield sweep runs $240 – $380, and the price is agreed in writing before we begin.
Creosote and Soot Removal
Burning wood produces creosote, a tar-like residue that condenses on your flue liner. Left alone, it hardens into a glaze that a standard brush can’t remove. We identify how far the buildup has progressed and tell you plainly whether it’s a routine sweep or whether the liner needs a more involved treatment.
Annual Sweep for Occasional Burners
Even if you only light a fire on holiday weekends, your chimney still captures leaf litter, twigs, and the occasional bird or rodent nest. In Kentfield’s canopy-heavy neighborhoods, we pull more debris off caps than most people expect. A once-a-year sweep keeps the flue clear and gives you a photo report of what we found.
Chimney Services in Kentfield
Chimney services in Kentfield go beyond the brush and vacuum. The first thing we check on any job here is the crown and flashing, because Kentfield’s rain season does more damage to mortar than fire ever will. A full Level 2 inspection with a camera runs $185 – $495 depending on the system, and it’s the only way to see cracks, gaps, or liner damage before they become a water intrusion problem. We also sweep, repair, and reline as needed, and every repair we make includes a written one-year guarantee.
Level 1 and Level 2 Inspections
A Level 1 is the standard annual check: accessible portions of the flue, cap, and firebox. A Level 2 gets the camera into the full flue run and is what you want after a heavy storm, before buying a home, or when you’ve had a chimney fire. In Kentfield, we recommend a Level 2 whenever water staining appears on the ceiling near the chimney chase.
Flue Relining and Crown Work
Flue relining (replacing the inner liner that channels smoke safely out of the house) becomes necessary when the existing liner cracks, spalls, or lets heat reach combustible framing. We install and work with DuraFlex and HeatShield products, and the decision to reline always comes with camera evidence you can see on the spot. Crown sealing and flashing repair are the most common masonry fixes we quote in Kentfield.

Trusted Brands We Service in Kentfield
We work with professional-grade chimney materials where the job calls for them: HeatShield for resurfacing deteriorated flue liners, Gelco for waterproofing and crown sealants, and Olympia Chimney and Famco for caps, dampers, and vents. We don’t spec materials by margin; we spec them by what your chimney actually needs. Our Kentfield routes stock common replacement parts so a crown sealant or cap replacement doesn’t turn into a two-week wait, and our written quote tells you which product we plan to use and why.
Common Chimney Sweep Problems We See in Kentfield Homes
- Leaf litter and nesting material on the cap: Kentfield’s mature oak and bay canopy drops twigs and leaves onto chimney caps all winter, and birds and squirrels treat an uncapped flue as move-in ready. A blocked cap is a common cause of smoky fireplaces and weak draft in Kent Woodlands and along College Avenue.
- Water-damaged crowns after wet winters: Hairline cracks in the crown let rain soak into the masonry, and repeated freeze-thaw cycles through the winter widen them. We check crown integrity on every Kentfield call because the local rain season is long and steady.
- Creosote glaze from occasional, low-temperature fires: Kentfield homes that burn a few fires a month often build a hard, shiny creosote glaze that a standard brush can’t remove. The flue looks clean on top but holds a flammable coating, which is why a camera check matters.
- Cracked or spalled flue liners going unnoticed: We’ve opened more than one flue in Kentfield where the liner had been failing for years because the previous sweep was a one-time booking with no inspection. The NFPA 211 standard calls for an annual inspection, and skipping it means liner damage compounds silently.
Pricing for Chimney Sweep in Kentfield, CA
A standard chimney sweep in Kentfield runs $240 – $380 for an open masonry fireplace with a clean flue. If the creosote has glazed or the flue hasn’t been swept in years, expect $380 – $550 because it takes more than a standard brush. A Level 2 camera inspection adds $185 – $295 on its own, or we bundle it with a sweep for a combined price that’s quoted in writing before we start. Crown sealing and flashing repair typically run $400 – $900 depending on access and materials. Every quote is a flat number you approve before any work begins, and you can call (830) 251-4560 for a free estimate.

FAQs About Chimney Sweep in Kentfield
Yes, and the reason has more to do with Kentfield’s trees and rain than with how often you burn. The NFPA 211 standard calls for an annual inspection because leaf litter, nesting material, water intrusion, and creosote buildup accumulate whether you burn weekly or twice a year. A one-time sweep without an inspection is how third-degree creosote glazes and cracked crowns go unnoticed between burns. Call (830) 251-4560 and we’ll give you a written price for the sweep and inspection as one job.
You don’t, until someone looks at the flue with a camera. First-degree creosote is a flaky black coating that brushes off easily; second-degree is a glossy glaze that needs mechanical or chemical treatment; third-degree is a hard, thick tar that can require flue relining to address safely. In Kentfield we regularly see second-degree glaze on chimneys that get occasional fires, and the only honest answer comes from camera evidence and a flat written quote for whatever the flue actually needs.
A standard Kentfield sweep runs $240 – $380. It includes brushing the flue and smoke chamber, clearing the cap and crown, a visual check of the firebox, and a photo report of the cleaned liner plus anything we found. We agree on the written price before the appointment, and that number doesn’t move after the fact. If the camera shows more involved work is needed, we show you the footage and quote that separately, and you decide.
It depends on what the camera shows. A routine sweep can happen any time, and spring is actually a smart window because it’s before the rainy season ends. But if the flue liner is cracked, the crown is spalling, or water is getting behind the flashing, waiting means masonry damage compounds through every storm. We had a homeowner off Sir Francis Drake Boulevard in Kentfield call about smoky backup in their firebox; our tech found a nest packed against the cap and a cracked crown that needed sealing before the next storm. We cleared the debris, ran a Level 2 camera inspection, brushed the flue, and sent them a photo report showing the cleaned liner and that crown crack. The crown repair was booked for a dry week rather than rushed, while the sweep happened immediately. Call (830) 251-4560 and we’ll tell you plainly what’s urgent and what isn’t.
In Kentfield, the usual cause we find is debris on the cap or a clogged upper flue, especially after leaf season. But it can also be a cold flue pushing smoke back into the room, a partially closed damper, or negative air pressure from a tight, well-sealed home. The fix requires looking at the whole system, not just brushing the flue, which is why every one of our sweeps includes a visual check of the cap, damper, and firebox as part of the written price. Call (830) 251-4560 and we’ll trace the actual cause instead of guessing.
