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 Kensington
A standard chimney sweep in Kensington typically runs $189 – $310, and most homes need one every 1 – 3 years depending on how often you burn. We cover every street in Kensington, from the hills above Arlington Avenue down to Colusa Circle, with the same process on every job: a written price before work starts, a camera inspection, and a photo report you keep. Call (830) 251-4560 to book an estimate. We’re not going to tell you to reline a flue unless our camera shows you exactly why.
Kensington’s tree canopy changes what we find here. Oak and eucalyptus drop debris well past November, and wind-driven rain off the bay works its way into caps and crowns that would stay dry in flatter, barer neighborhoods. A sweep visit in Kensington often turns up a clogged cap or a cracked crown rather than just soot. That changes the job and changes what you should expect from a chimney company. We know what to look for on these hills.
Why Flint Chimney Sweep Is Kensington’s Preferred Chimney Sweep Company
Hank Delano leads our team, and he runs every Kensington job under the same Garrison Standard we’re known for: a written price handed over before any tool comes off the truck. Homeowners here have dealt with no-shows and price changes at the door. That doesn’t happen with us because our process doesn’t allow it. The price you approve is the price on the invoice.
We’re part of the Garrison Partners family, founded in 2002. Our technicians are background-checked and uniformed, so you know exactly who is at your door before you open it. A live person answers our phone 24 hours a day. Not an answering service. Not a voicemail tree. If you call at 10 p.m. with a question about your chimney, a human picks up.
Kensington homeowners see us on the hillsides off Arlington Avenue, in the mid-century ranches near Kensington Park, and along the winding streets above Colusa Circle. We understand these houses: masonry chimneys on 1940s and 1950s builds, fireplaces that haven’t been swept in a decade, and caps rusted through by bay moisture. We don’t have to learn your neighborhood. We already work here.
Chimney Sweep Services in Kensington
Chimney Sweep Services in Kensington means more than running a brush up the flue. We remove creosote and soot from the full length of the flue, check the damper, cap, and crown, and run a camera through the system so you see the condition of the liner with your own eyes. A standard sweep in Kensington runs $189 – $310.
Creosote and Soot Removal
Creosote is the tar-like residue left behind when wood smoke cools and condenses inside the flue. It’s combustible, and it builds up faster when a chimney doesn’t draft well or when a homeowner burns unseasoned wood. We remove first-, second-, and third-degree creosote using brushes sized to the exact flue dimensions. After the sweep, our camera confirmation shows you a clean liner, not just our word for it.
Fireplace Cleaning and Annual Sweep
An annual sweep covers the firebox, smoke chamber, damper assembly, and flue. We vacuum the firebox, remove ash and debris, and inspect the damper for rust and seal failure. In Kensington’s older homes, we commonly find dampers that no longer close fully, which lets warm house air escape up the chimney all winter. We’ll show you that on the camera and explain whether a replacement makes sense.

Chimney Cleaning in Kensington
Chimney Cleaning in Kensington starts with a Level 1 or Level 2 inspection so we know exactly what we’re dealing with before a brush goes up. A Level 1 inspection is included with every sweep and covers the accessible portions of the chimney interior and exterior. A Level 2 inspection adds a video camera scan of the flue interior and runs $149 – $249 when added to a sweep.
Why Camera Inspection Matters in Kensington
Kensington’s older masonry chimneys hide problems a brush can’t reach. A camera shows hairline cracks in the flue liner, spalling brick in the smoke chamber, and creosote glaze hardened in place. Without the camera, you’re trusting someone to describe what they can’t see. We don’t guess. You get photos of the cleaned liner and any damage we find, so the recommendation comes with evidence.
Level 1 vs Level 2: What You Actually Need
A Level 1 inspection is fine when your chimney is used the same way every year and nothing has changed. A Level 2 inspection is the right call after a storm, after buying a home, or after any event that could have damaged the flue, such as a chimney fire or an earthquake. In Kensington, where wind and eucalyptus debris hammer caps and crowns all winter, a Level 2 gives you a real picture of what the weather did to your chimney.
Trusted Brands We Service in Kensington
We install and work with professional-grade chimney components from HeatShield, Gelco, and Olympia Chimney. These aren’t the cheap parts you find at a big-box store. HeatShield is a ceramic resurfacing system we use to repair damaged flue liners without a full rebuild. Gelco makes caps and chase covers that stand up to bay-area moisture. Olympia Chimney manufactures dampers and connectors that perform in the tight flues common in Kensington’s older homes. Because we use these brands, repair parts for Kensington jobs are often available quickly, and the work carries our written one-year guarantee under the 365-Day Done Right Promise.
Common Chimney Sweep Problems We See in Kensington Homes
- Clogged or damaged chimney caps after wind storms. Kensington sits on the eastern slope of the Berkeley Hills, and storm winds funnel leaves and eucalyptus bark right into exposed caps. A cap full of debris chokes the draft and pulls smoke back into the house.
- Second- and third-degree creosote hidden above the damper. A brush-only sweep misses the hard, tar-like creosote that forms when a chimney is under-swept and the fire burns low and smoky. Our camera shows exactly where it is before we go after it.
- Cracked crowns letting water into the smoke chamber. Kensington’s wet winters expand and contract the mortar on chimney crowns. Once water gets behind the crown, it spalls brick and rusts the damper. A sweep visit catches this early, when the fix is a crown repair, not a tear-down.
- Rusted dampers that no longer seal. Older Kensington houses often have original throat dampers that rust open just enough to leak conditioned air all winter. You’ll notice a cold fireplace in winter and a drafty living room. Replacing the damper is a straightforward fix we quote in writing before any work starts.

FAQs About Chimney Sweep in Kensington
Every one to three years, depending on how often you burn and what you burn. If you use your fireplace weekly during fall and winter, sweep it annually. If it’s occasional use, every two to three years is usually enough. Kensington’s damp, leaf-heavy environment means caps and crowns should be checked even in years when a full sweep isn’t needed. Call (830) 251-4560 and we’ll tell you what your fireplace actually needs, not what our calendar says.
Yes. Every sweep includes a camera photo report. You’ll see the cleaned flue, any creosote we removed, and any damage we found. If we recommend a repair or a new liner, we show you the photos that justify it. If we don’t recommend anything, you’ll see a clean flue and know you’re fine until next season.
A Level 2 inspection costs $149 – $249 when added to a sweep. It’s not required on every job. We recommend it after storms, after a home purchase, or when our Level 1 check shows something we want to see more clearly with the camera. You’ll know the price before we do it.
First-degree creosote is a light, dusty layer. It’s not an immediate fire hazard, and if that’s all our inspection finds, waiting a year is usually fine. Second-degree creosote is a different story: it’s hardened and flaky, and it can ignite under the right conditions. Third-degree creosote is the tar-like glaze that’s hardest to remove and most dangerous. We’ll tell you plainly which one you have and whether waiting is safe. No scare tactics, just what the camera shows.
Yes, and it’s the reason we check the draft and the damper on every sweep. A blocked flue or a rusted damper that won’t open can send carbon monoxide back into the house. Kensington’s hillside homes, with their older masonry chimneys and tree-heavy lots, are exactly the kind of setting where a blocked cap becomes a CO risk. If your chimney drafts poorly or your carbon monoxide detector has gone off, call (830) 251-4560. This is one of the few things we’ll tell you not to wait on.
