Why Hearthstone Chimney Co. of San Francisco Is Kensington’s Preferred Fireplace Services Company
We’ve been serving Kensington and the surrounding East Bay hills for over 42 years - since 1984 - and in that time we’ve worked on hundreds of the original masonry chimneys that define this neighborhood. Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics.
Calls are answered by a live person, not a voicemail system or callback queue. That matters when you smell smoke in the living room at 6 p.m. on a December evening. Our 90-Day Done Right Promise is backed in writing - if it’s not right, we come back, no arguing, no paperwork chase.
We understand Kensington’s particular situation: a tiny, hillside community where nearly every home was built between 1920 and 1950, where chimneys predate modern codes by decades, and where the memory of the 1991 Oakland-Berkeley Hills firestorm still shapes how residents think about hearth safety. We treat every service call here with that context in mind.
Our Fireplace Services in Kensington
Gas Fireplace Service
Gas fireplace service in Kensington runs $180-$320 for a standard tune-up and safety inspection. Many homeowners in Kensington’s 1920s bungalows and Tudor Revivals have converted original wood fireplaces to gas inserts to avoid dealing with aged flue systems, but even gas units need annual inspection of valves, thermocouples, and venting. We service direct-vent and vent-free units from major manufacturers, checking for proper combustion, clearances, and gas-line integrity. If your pilot won’t stay lit or you’re getting soot buildup on the glass, that’s a call worth making before the heavy season starts.

Wood Burning Fireplace
Wood burning fireplace inspection and sweeping in Kensington typically costs $250-$380, with repairs to firebox or liner added on top. The marine-layer damp that rolls through Kensington’s hills keeps flues moist year-round, and infrequently used fireplaces often develop poor draft from moisture-saturated flue walls. On first-of-season calls, we regularly hear that a fireplace that worked fine last winter is now smoking into the room. That’s usually a combination of damp creosote buildup and a damper that has corroded or shifted over the summer. We clean, inspect with a Level-2 camera, and tell you exactly what you’re dealing with.

Fireplace Insert
Fireplace insert installation in Kensington ranges from $2,800-$4,500 for a quality unit with proper venting, including stainless-steel liner and surround. For homeowners with original clay-tile flue liners that are cracked or offset - common in Kensington’s pre-1950 housing stock - an insert with a dedicated vent pipe is often the most practical path to a safe, efficient hearth. We size inserts to your existing firebox opening and install DuraFlex stainless-steel liners rated for the application. Done right, an insert can cut your heating costs and eliminate the draft problems that plague old masonry chimneys in this climate.

Damper Repair
Damper repair or replacement in Kensington runs $180-$450 depending on whether we can rebuild the existing throat damper or need to install a new top-sealing model. Original cast-iron throat dampers in Kensington’s older homes corrode, warp, or jam with creosote; the pivot pins rust through, and the plate no longer seats squarely. A failed damper costs you heated air up the flue year-round and can allow rain and animal entry. We stock replacement dampers and can often complete the repair same-day.

Firebox Repair
Firebox repair in Kensington typically runs $350-$1,200, with HeatShield refractory resurfacing at the lower end and partial rebuild with new firebrick at the higher end. The original lime-based mortar in Kensington’s 1920s-1950s fireboxes has often eroded from decades of thermal cycling and moisture intrusion, exposing the structural masonry behind it. We recently serviced a 1929 Tudor Revival on Southwood Drive where the original clay-tile flue liner had shifted, causing a 3/8-inch gap that allowed carbon monoxide to seep into the living room. Using HeatShield’s ceramic repair system, we sealed the liner without demolition, then installed a DuraFlex stainless-steel liner for future safety - a solution that cost about half of a full chimney rebuild and brought the chimney up to modern code.

Trusted Brands We Service in Kensington
We work exclusively with professional-grade materials: DuraFlex stainless-steel liners, HeatShield refractory repair systems, Gelco chimney caps, and hardware from Olympia Chimney, Famco, and Copperfield. These are the brands we trust for Kensington’s demanding conditions - marine-layer moisture, hillside wind exposure, and the thermal stress of original masonry that has already seen nearly a century of use. We stock common parts and liners in our service vehicles, which means most Kensington jobs are completed in a single visit without waiting on special orders.
Common Fireplace Services Problems We See in Kensington Homes
- Cracked or offset clay-tile flue liners in 1920s-1950s masonry chimneys allow heat and smoke to escape into adjacent wood framing. We find this on roughly half the Level-2 inspections we perform in Kensington’s older homes, and it’s a genuine fire hazard that demands attention.
- Eroded lime-based mortar joints on southwest-facing chimneys, accelerated by persistent fog and wind rolling off the Bay, lead to loose bricks and structural instability. The exterior chimneys on Kensington’s hillside homes take the full brunt of that onshore flow, and the Bay-facing side often needs repointing two or three cycles before the sheltered side shows any wear.
- Poor draft from moisture-logged flues in infrequently used fireplaces causes smoke spillage into the home on first cold-day fires. Kensington’s marine-layer climate keeps flue walls damp for months, and that moisture suppresses the temperature differential that drives proper draft.
- Deteriorated firebox mortar and heat-damaged brick in original construction that was never designed for the burn patterns of modern use. Original fireboxes in Kensington were built with soft firebrick and lime mortar that degrades faster than modern refractory materials.

FAQs - Fireplace Services in Kensington
It’s almost certainly a combination of moisture-saturated flue walls and a damper that isn’t sealing or opening fully. Kensington’s marine-layer climate keeps chimneys damp, and that moisture suppresses the hot draft column that carries smoke upward. After a long summer of disuse, the first cold-day fire often spills smoke into the room until the flue warms and dries. We can inspect with a camera, clean the system, and check damper operation - call (855) 408-5567 for an appointment; estimates are free.

In most cases, yes. We use HeatShield’s ceramic flue sealant system to fill cracks and gaps in existing clay-tile liners, then install a DuraFlex stainless-steel liner for long-term protection. This approach costs roughly half of a full rebuild and avoids the mess and structural disruption of demolition. The 1929 Southwood Drive job we mentioned above is a typical example - sealed and relined in two days, no scaffolding, no dust through the house.

Not necessarily, but you do need a chimney that operates safely. Original chimneys in Kensington are grandfathered, but if you’re doing significant repair, conversion, or real estate transaction work, current codes often apply to the modified portion. Our Level-2 inspection includes a code assessment specific to your situation. We’ll tell you what’s required, what’s recommended, and what can wait - plain English, no pressure.

Moisture has accumulated in the flue and firebox, and organic debris - leaves, animal nesting material, creosote - has begun to decompose. Kensington’s persistent marine-layer damp makes this worse than in drier inland climates. A thorough sweeping removes the source, and we can recommend a proper chimney cap from Famco or Gelco if yours is missing or inadequate. Call for the $89 seasonal tune-up before you light the first fire.

It depends on the condition of your existing liner, and that’s not a guess we make without a camera inspection. Gas burns cooler and wetter than wood, and an already-compromised clay-tile liner can deteriorate faster under gas combustion byproducts. If your liner is cracked or offset, we recommend repair or stainless-steel relining before conversion. The inspection cost is modest; the risk of skipping it is not. Call (855) 408-5567 to schedule; estimates are free.
