We’ve been driving out to Kentfield from San Francisco for over 42 years, and we know the roads well: Sir Francis Drake Boulevard winding through the redwoods, College Avenue climbing toward the Marin hills, the quiet lanes off Woodland Road where the old estates sit. Our technicians are usually at your door within 90 minutes of your call. That matters when you’ve got smoke backing up into the living room or a cracked liner that’s letting carbon monoxide slip into the wall cavity.
Kentfield chimneys are different. The fog doesn’t just roll in - it gets squeezed from the sky by the surrounding hills, and that moisture works its way into every mortar joint and clay tile. We’ve learned what fails here, and we’ve learned what lasts.
Why Hearthstone Chimney Co. of San Francisco Is Kentfield’s Preferred Chimney Liner & Rebuild Company
Warren Eckhart started this company in 1984 with a simple standard: do the job right, document what you found, and stand behind it. That standard hasn’t changed. Kentfield homeowners call us because they’ve had the other kind of contractor - the one who gives a verbal estimate, disappears for weeks, and won’t pick up the phone when something isn’t right.
We answer differently. A live person picks up our line 24 hours a day, 7 days a week. No voicemail. No callback queue. Our background-checked, uniformed technicians arrive with a camera, a plain-English verdict, and photos you can see on the spot. Most liner and rebuild jobs in Kentfield finish in one visit. The price we quote is the price on the invoice - no surprises on the bill.
Our 90-Day Done Right Promise covers every job in writing. If it’s not right, we come back. No paperwork to dig up, no arguing. That’s the Keystone Standard we’ve operated by since 1984, and it’s why Kentfield homeowners who hire us once tend to call us back for every fireplace issue that follows.
Our Chimney Liner & Rebuild Services in Kentfield
Stainless Steel Liner Installation
Stainless steel liners are what most Kentfield homes need, whether we’re working on a 1920s estate off Woodland Road or a mid-century ranch near College Avenue. The original clay flue tiles in these houses were never designed to withstand decades of fog-driven freeze-thaw cycles. We install DuraFlex stainless steel systems that flex with thermal expansion and resist the acid attack from moist creosote. A typical stainless steel liner installation in Kentfield runs $2,800-$4,800 for a standard single-flue chimney.
Flexible Liner Systems
Some Kentfield chimneys have offsets, bends, or tight clearances that rigid pipe can’t navigate - especially in the older homes with modified flues near Sir Francis Drake Boulevard. Flexible liners from DuraFlex thread through these problem passages without breaking the masonry envelope. We size them precisely for your appliance, whether it’s a wood-burning fireplace or a gas insert conversion. Flexible liner jobs in Kentfield generally fall between $3,200-$5,500.
Liner Replacement
Full liner replacement is our most common Kentfield service. The clay tiles crack. The mortar between them crumbles. Suddenly you’ve got gaps that let heat and combustion gases reach the wooden framing. Our Level-2 camera inspection finds every breach, and we document it with photos you can see. Then we pull the damaged liner and install a new system, usually in one day. Liner replacement in Kentfield typically costs $2,800-$6,500 depending on flue count and height.
Partial Chimney Rebuild
When the liner damage extends into the surrounding masonry, a liner alone won’t fix it. We see this often in Kentfield’s pre-war homes where oversized fireboxes were built to obsolete standards and the smoke chamber was parged with inferior mortar. Partial rebuilds restore the firebox, smoke chamber, or upper chimney structure to modern code while the new liner goes in. These jobs run $4,200-$9,000 in Kentfield.
Full Chimney Rebuild
The worst cases need the full treatment: tear-down and rebuild from the roofline up, sometimes from the ground up. This is rare, but we’ve done it on Kentfield homes where decades of moisture intrusion have compromised the structural integrity of the stack. We match existing brick and mortar color where possible, and every rebuild includes a new stainless steel liner system. Full chimney rebuilds in Kentfield range from $12,000-$22,000.
Liner Repair
Not every cracked liner needs replacement. Small, accessible breaches sometimes qualify for targeted repair using HeatShield cerfractory sealant, a professional-grade refractory compound that restores the flue surface to UL-listed standards. We only recommend this when camera inspection confirms the damage is localized and the surrounding tiles are sound. Liner repair in Kentfield runs $1,800-$3,200 when it’s a viable option.

Trusted Brands We Service in Kentfield
We don’t use builder-grade substitutes. Our Kentfield crews carry professional-grade materials from DuraFlex, Olympia Chimney, Famco, and Copperfield - brands that hold up in this climate. DuraFlex stainless steel liners handle the thermal cycling and acid exposure that fog-moistened creosote creates. Famco and Copperfield caps and dampers block the redwood needle drop that clogs uncapped flues across Kentfield. We stock these parts locally, so we’re not waiting on shipping while your chimney sits open to the weather. That means faster turnaround and a job that lasts.
Common Chimney Liner & Rebuild Problems We See in Kentfield Homes
- Clay liners crack faster here due to fog-driven freeze-thaw cycles. The orographic lift in Ross Valley squeezes moisture from passing systems year-round, and Kentfield’s masonry chimneys never fully dry out. Water penetrates hairline cracks in clay tiles, freezes overnight, and widens the gap. Hidden gaps allow carbon monoxide seepage into wall cavities - a hazard camera inspection reveals before it becomes dangerous.
- Moisture absorption in uncapped flues promotes heavy moss growth on the crown. We’ve lifted caps in Kentfield to find the crown entirely carpeted in moss and lichen. That living layer traps water against the masonry, accelerates spalling, and sends moisture straight down onto the liner. It’s a repair cascade that starts with a missing or failed cap.
- Oversized fireboxes built to obsolete mid-century standards require partial rebuilds. Many Kentfield homes built between the 1940s and 1960s have fireboxes too large for modern inserts or liners. The throat is wrong. The smoke chamber is too steep. We routinely reconfigure these as part of liner replacement, adding scope that the homeowner didn’t expect but that the job demands.
- Redwood canopy debris fills uncapped flues every rainy season. The dense overhang of coast redwoods, coast live oaks, and California bay laurel on Kentfield lots drops needle cast, bark shreds, and nesting material directly into open flues. Our technicians pull out substantial organic debris alongside creosote after every winter - and we always recommend a cap.
Pricing for Chimney Liner & Rebuild in Kentfield, CA
Here’s what chimney liner and rebuild work costs in Kentfield’s market:
| Service | Typical Range |
|---|---|
| Stainless Steel Liner Installation | $2,800 - $4,800 |
| Flexible Liner System | $3,200 - $5,500 |
| Liner Replacement (full) | $2,800 - $6,500 |

| Full Chimney Rebuild | $12,000 - $22,000 |
Several factors push these numbers up or down. Chimney height matters - a two-story flue costs more than a single-story. Access matters - steep roofs or tight side yards add labor. The condition of the existing masonry matters most of all. We’ve opened Kentfield chimneys that looked fine from the roof and found the liner in pieces at the bottom. That’s why we start every job with a Level-2 camera inspection: photos you can see, a plain-English verdict, and a fixed price before any work begins. Estimates are free. Call (855) 408-5567 to schedule.
In Kentfield, the combination of heavy redwood canopy and fog-channeled moisture means chimneys often require both liner replacement and stainless steel cap installation simultaneously - a need rarely seen in drier East Bay towns like Lafayette. We price these combined jobs together, and the cap installation typically adds $400-$800 to the liner scope. Doing both at once saves you a second service call and prevents the moisture intrusion that would damage your new liner.
On a recent job in the quiet cul-de-sac of Merlone Way, we found a 1950s estate fireplace with a cracked clay flue liner from decades of fog-induced freeze-thaw. We replaced the entire liner with a DuraFlex stainless steel system and added a copper chimney cap to block the constant redwood needle drop - a fix our Chimney Liner & Rebuild crew handles regularly.

FAQs - Chimney Liner & Rebuild in Kentfield
Kentfield’s orographic rainfall and persistent fog keep masonry chimneys damp year-round, accelerating clay tile deterioration through freeze-thaw cycling that San Francisco’s drier microclimates simply don’t produce. San Francisco chimneys face salt air and seismic stress, but they don’t stay wet enough to shatter clay liners from the inside out. We replace Kentfield liners at roughly twice the rate we do in the city proper. Call (855) 408-5567 for a camera inspection to see if yours is due.
Needle drop accelerates liner corrosion by trapping moisture and organic acids against the flue surface, and it physically blocks proper draft when it accumulates at the smoke chamber. In Kentfield, we routinely remove gallons of compacted redwood debris during liner replacement jobs - debris that would have destroyed a new liner within seasons if left unaddressed. Every liner replacement we do in Kentfield includes a cap recommendation, and most homeowners add it once they see the photos from their flue.
Structural leaning, widespread mortar loss, and spalled brick through multiple courses indicate a full rebuild; isolated firebox cracking or a single damaged flue course usually means partial work suffices. In Kentfield’s 1920s-1940s estates, we often find the upper chimney has deteriorated past saving while the lower structure remains sound - a partial rebuild with new liner handles this. Camera inspection and a thorough exterior evaluation tell the difference. We’ll show you the photos and give you both options where they exist.
Yes - the sustained moisture from Ross Valley’s orographic lift rules out aluminum and lower-grade alloys that corrode quickly in damp flues; we specify 316Ti stainless steel or higher for every Kentfield installation. DuraFlex and Olympia Chimney systems we install are rated for this environment. The material choice isn’t arbitrary here. It’s matched to a climate that destroys lesser metals.
Kentfield’s fog-moistened creosote forms a sticky, corrosive layer that masks cracked clay tiles from visual inspection, and the thermal cycling from occasional use creates hairline fractures that only camera inspection reveals. Homeowners often call for a routine sweep and learn their liner is compromised - it’s so common we’ve built our inspection protocol around finding what others miss. The good news: catching it during sweep service means fixing it before carbon monoxide becomes a threat. Call (855) 408-5567 to book your inspection - estimates are free.
