We’ve been driving out to Kensington from San Francisco for more than four decades. We know the difference between a chimney on the fog-exposed southwest face of a hillside Tudor and one tucked behind a Craftsman on a sheltered lane. That local knowledge matters because Kensington’s chimneys fail in specific, predictable ways that inland sweeps often miss. Our Chimney Cleaning & Sweep team treats every job in the 94530 ZIP as a safety-critical inspection, not a routine brush-out.

Our Chimney Cleaning & Sweep Services in Kensington
Level 1 Inspection
A Level 1 inspection is the baseline for any chimney cleaning in Kensington. We examine the readily accessible portions of your chimney exterior, interior, and flue, checking for obstructions, creosote buildup, and basic structural soundness. For Kensington’s older homes with original clay-tile liners, this inspection catches the obvious problems, though it won’t reveal hidden flue damage. A Level 1 with cleaning runs $180-$260 in the Kensington market.
Level 2 Inspection
This is where we do our best work in Kensington. A Level 2 camera inspection uses a high-resolution chimney camera to examine the full length of your flue, the smoke chamber, and the firebox. We document every crack, gap, and glaze with photos you can see. For Kensington’s 1920s-1950s chimneys with original clay-tile liners, this is often the only way to find the moisture-induced cracking that creates hidden fire hazards. On a recent Level 2 inspection in the southwest-facing wall of a 1920s Tudor Revival near the intersection of Arlington and Moeser Lane, our tech found the Bay-facing mortar joints eroded two repointing cycles ahead of the sheltered side, with a cracked clay-tile flue liner that would have failed a smoke test. We recommended a DuraFlex stainless steel liner installation and three courses of repointing on the exposed face. Level 2 inspections in Kensington run $320-$480.
Creosote Removal
Kensington’s damp marine-layer climate creates a specific creosote problem. Moisture-laden flues produce more glazed creosote, the hard, tar-like deposit that standard brushing won’t remove. We use professional-grade mechanical whips and polypropylene brushes designed for glazed deposits, not the soft brushes some chains use to speed through appointments. Heavy glazed creosote removal in Kensington runs $280-$420 depending on flue length and buildup severity. Annual sweeping prevents this condition from developing.
Soot Removal & Annual Sweep
An annual sweep removes soot and light creosote before they harden into glazed deposits. For Kensington homeowners who use their fireplaces occasionally, this is the most cost-effective maintenance. The damp climate here means even infrequently used chimneys accumulate moisture-driven deposits that reduce draft and accelerate liner deterioration. Our annual sweep service in Kensington is $180-$260, and we schedule recurring appointments so you don’t have to remember. The $89 Seasonal Tune-Up is available for qualifying systems.
Fireplace Cleaning
We clean fireboxes, smoke chambers, and hearths as part of our sweep service, or as standalone work for Kensington homeowners preparing for sale or inspection. Old firebox mortar in Kensington’s pre-1950s chimneys often shows heat-induced spalling that looks like soot but signals deeper problems. We flag it, photograph it, and explain what it means.

Trusted Brands We Service in Kensington
We stock and install professional-grade materials from Gelco, Olympia Chimney, and Famco, among others. For Kensington’s aging masonry chimneys, we keep DuraFlex stainless steel liner components in our trucks because original clay-tile failures are that common in this neighborhood. When a southwest-facing chimney needs repointing after fog-driven erosion, we don’t wait two weeks for parts. That local inventory means most Kensington jobs finish in the single visit we promised.
Common Chimney Cleaning & Sweep Problems We See in Kensington Homes
- Southwest-facing exterior chimneys suffer accelerated mortar erosion. The prevailing fog-laden onshore wind hits the Bay-facing side first and hardest. We inspect that face before the sheltered side, because it often needs repointing years earlier. Many Kensington homeowners are surprised to learn their chimney has two different conditions.
- Original clay-tile flue liners crack from moisture cycling. Kensington’s marine-layer dampness repeatedly expands and contracts old tile. The cracks are invisible from the firebox and undetectable without a camera. We’ve found failed liners in chimneys that looked fine from the roof.
- Unlined or single-wythe brick chimneys fail post-1991 firestorm safety standards. Kensington’s position on the fringe of the 1991 Oakland-Berkeley Hills fire zone means local fire consciousness runs high. Many original chimneys need stainless steel liners to pass current safety expectations, even if they met code when built.
- Poor draft on first-of-season fires. Moisture-saturated flues in Kensington’s damp climate struggle to establish upward airflow. Homeowners smell smoke or get backdraft until the flue dries and warms. Annual sweeping and inspection identifies whether this is normal seasonal dampness or a blockage requiring correction.

FAQs - Chimney Cleaning & Sweep in Kensington
The prevailing onshore wind carries salt-laden fog directly against southwest-facing chimney walls, accelerating spalling and erosion in old lime-based mortar. Your sheltered side may look fine while the exposed face needs repointing. We inspect the Bay-facing side first on every Kensington job. Call (855) 408-5567 to schedule an inspection - estimates are free.
Probably, if your chimney still has original clay tile or no liner at all. Kensington’s post-1991 fire safety awareness means unlined or cracked-tile chimneys often fail modern inspection standards, and the damp climate accelerates the damage. A DuraFlex stainless steel liner is the standard upgrade we recommend for most pre-1950s Kensington homes. We’ll show you camera footage of your flue and explain exactly what we found.
Annually, even if you use the fireplace infrequently. Kensington’s marine-layer moisture creates deposits and draft problems that inactive chimneys in drier climates don’t face. An annual sweep catches moisture-driven deterioration before it becomes expensive repair. We offer recurring scheduling so you don’t have to track it.
Check the Bay-facing mortar for white efflorescence, flaking surface, or missing mortar joints. Inside, smell for persistent damp or musty odors from the firebox, and note any smoke spillage on first fires of the season. These are early warnings in Kensington’s fog-driven environment. Don’t climb the roof yourself - call us for a ground-to-crown inspection.
Yes. Our Level 2 camera inspection sends a high-resolution camera up the flue without disturbing existing tiles. We photograph cracks, gaps, and glaze deposits the entire length. For Kensington’s original clay-tile chimneys, this is the standard method to evaluate hidden condition. The inspection takes about an hour, and you’ll see the photos same-day.
