Why Hearthstone Chimney Co. of San Francisco Is Larkspur’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimneys along Larkspur’s hillside streets long enough to recognize the tar-black glaze of eucalyptus creosote before we even set up the ladder. That local knowledge matters. A liner job in 94939 starts with knowing whether the flue has been compromised by salt-fog corrosion or by oil-rich deposits from locally harvested firewood.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the flue is cracked, we show you the crack. If it’s sound, we say so.
We back every liner and rebuild with the 90-Day Done Right Promise in writing. Not a handshake. Not a verbal. In writing, no arguing. If it’s not right, we come back.
Most Larkspur calls reach us within 30 minutes during business hours, and our background-checked, uniformed technicians complete most liner and rebuild jobs in a single visit. The number on your estimate is the number on your invoice.
Our Chimney Liner & Rebuild Services in Larkspur
Stainless Steel Liner Installation
For Larkspur homes with deteriorated clay-tile flues or original unlined brick, we install 316-grade stainless steel liners from DuraFlex and Olympia Chimney. In 94977 and the canyon neighborhoods, we specify grade-316 over 304 because eucalyptus creosote is unusually acidic and will pit lesser steel within a few seasons. A typical stainless steel liner installation in Larkspur runs $2,800-$4,200 for a standard fireplace flue, including the Level-2 inspection, the liner, insulation, and proper top termination. Homes with multiple appliances or offset flues run higher.
Flexible Liner Systems
Many Larkspur chimneys, especially the Victorians and Craftsmans off Magnolia Avenue, have offset flues or narrow passages that won’t accept rigid pipe. We use DuraFlex flexible liners that navigate these offsets while maintaining proper draft. Flexible liner jobs in Larkspur typically fall between $3,200-$5,000 when offsets or multiple bends are involved. The work includes a camera verification that the liner seats correctly at the thimble and crown.
Liner Replacement
When an existing liner has failed due to corrosion, thermal shock, or improper original installation, we remove and replace it. In Larkspur’s fog belt, we often find that cheap 304-grade liners or improperly terminated systems have rusted from the top down, letting water intrude through a corroded cap. Liner replacement runs $3,500-$5,500 in this market, depending on accessibility and whether the surrounding masonry needs repair. We document the old liner’s condition with photos before removal.
Partial Chimney Rebuild
For Larkspur canyon homes where the upper masonry has spalled from freeze-thaw cycling or where the crown has cracked and saturated the brick, we rebuild from the roofline up. This is common in Madrone Canyon and on hillside parcels where wind-driven salt fog accelerates mortar deterioration. A partial rebuild with new liner installation typically runs $4,500-$7,500. We match existing brick where possible and pour a proper concrete crown with drip edge and waterproofing.
Full Chimney Rebuild
When the entire structure is compromised, we dismantle and rebuild. This is the reality for some of Larkspur’s oldest unlined chimneys where decades of eucalyptus burning have created glazed creosote deposits that ignited, causing thermal shock cracks from crown to smoke chamber. Full rebuilds in Larkspur range from $6,500-$8,500 and include a new DuraFlex or Olympia Chimney stainless liner system, proper clearance to combustibles, and full fire-code compliance for Marin County’s High Fire Hazard Severity Zone requirements.
Liner Repair
Not every compromised liner needs full replacement. For localized cracks or gaps in otherwise sound clay tile, we evaluate whether HeatShield cerfractory flue sealant or a stainless steel sleeve is appropriate. Liner repair in Larkspur runs $1,800-$3,200. We only recommend repair when we’re certain it restores safe, code-compliant operation.

Trusted Brands We Service in Larkspur
We work exclusively with professional-grade materials: DuraFlex for flexible and rigid stainless liners, Olympia Chimney for cap and termination hardware, and Famco for custom chase covers when salt-fog corrosion has destroyed the original. We stock common liner diameters and termination kits for Larkspur’s typical fireplace and insert configurations, which means faster turnaround and no waiting on freight.

Common Chimney Liner & Rebuild Problems We See in Larkspur Homes
- Eucalyptus creosote accelerates liner deterioration. Larkspur residents burning fallen eucalyptus from the hillside slopes produce a thick, tar-like third-degree creosote after a single season. This deposits oil-rich acids that pit 304-grade stainless steel and degrade clay tile. We flag these flues for immediate Level-2 inspection before any liner work proceeds.
- Salt-laden fog corrodes exposed metal. The marine air funneling through the Ross Valley gaps carries enough salt to destroy chimney caps and chase covers within five to seven years. Once water intrudes, the liner rusts from the outside in. We replace failed caps with marine-grade stainless or copper and verify liner integrity.
- Short, cool fires glaze unlined flues. Larkspur’s fog belt keeps evening temperatures low, so residents burn small fires for ambiance rather than heat. These low-temperature burns in a cool, damp flue produce glazed creosote faster than hot, roaring fires. Unlined brick chimneys in the historic core are especially vulnerable to ignition and thermal shock cracking.
- Original unlined chimneys fail fire code. Homes from the 1890s-1930s in the historic downtown and canyon neighborhoods were built without liners. Marin County’s High Fire Hazard Severity Zone designations for hillside parcels mean these chimneys often cannot pass inspection for sale or insurance without liner installation or rebuild.

FAQs - Chimney Liner & Rebuild in Larkspur
Eucalyptus wood produces oil-rich creosote that is more acidic and deposits faster than standard hardwoods, pitting unprotected steel and degrading clay tile within one to two seasons. In Larkspur’s canyon neighborhoods where residents burn fallen eucalyptus as free firewood, we regularly find thick, tar-like glaze that demands immediate Level-2 inspection and liner installation to prevent flue ignition. Call (855) 408-5567 to schedule an inspection if you’re burning eucalyptus.
Yes. Homes built in Larkspur’s historic core before the 1940s were constructed with unlined brick flues that do not meet current fire codes, especially in Marin County’s High Fire Hazard Severity Zone areas. On a Madrone Canyon Craftsman with an original 1910 unlined chimney, we found a thick, oil-rich creosote glaze from eucalyptus burning. We installed a DuraFlex stainless steel liner after a Level-2 inspection revealed cracks from thermal shock, restoring safe draw and fire-code compliance. Call (855) 408-5567 for a free inspection of your historic chimney.
The cool marine air that funnels through the Ross Valley gaps keeps flue temperatures low and extends the burning season, which increases creosote buildup, while salt-laden fog corrodes exposed metal caps and chase covers that protect the liner from water intrusion. We address this by specifying grade-316 stainless steel for all Larkspur liner jobs and replacing failed terminations with marine-grade materials. Call (855) 408-5567 if you notice rust stains on your chimney exterior.
A partial rebuild removes damaged masonry from the roofline up, replaces spalled brick and deteriorated mortar, pours a new concrete crown with proper drip edge and waterproofing, and installs a new stainless steel liner system to current code. For Larkspur hillside homes in 94939, we often encounter mortar degradation from salt-fog exposure and may need to rebuild the upper third of the chimney while preserving original character below. Most partial rebuilds with liner installation are completed in two days. Call (855) 408-5567 for an exact quote.
You can, but you must burn it properly and inspect annually. A grade-316 stainless steel liner resists eucalyptus creosote better than unlined brick or 304-grade steel, but no liner eliminates the need for regular cleaning. We recommend annual Level-2 inspections for Larkspur homes that burn eucalyptus, with sweeping as needed based on creosote accumulation. Call (855) 408-5567 to schedule your post-installation inspection and set up a maintenance schedule.
