Our Chimney Liner & Rebuild Services in San Anselmo
Stainless Steel Liner Installation
A stainless steel liner is the standard permanent fix for cracked clay flue tiles in San Anselmo’s older homes. We install DuraFlex and Olympia Chimney stainless systems that carry lifetime warranties and handle the temperature swings of both wood-burning and gas conversions. For homes on the steep hillside lots above the valley floor, where northwest downdrafts are common, we size and cap these liners specifically to maintain proper draft against wind pressure.
Flexible Liner Solutions
Some San Anselmo chimneys, particularly the offset flues in Tudor cottages around Crescent Road, cannot accept a rigid liner. We use flexible stainless systems that navigate bends and transitions without compromising airflow or safety. These are especially useful in homes where previous modifications have altered the original flue path.
Liner Replacement
When an existing liner has failed due to moisture intrusion, acid corrosion, or thermal shock, full replacement is often the only code-compliant option. We recently relined a 1928 Craftsman bungalow on Lansdale Avenue where decades of Ross Valley rain had cracked the original clay flue tiles. We installed a DuraFlex stainless steel liner with HeatShield sealant to prevent future moisture intrusion and restore draft performance. The job was done in one day, and the homeowner had photos of every stage.
Partial Rebuild
Not every damaged chimney needs to come down. When the upper courses of brick have spalled from rain exposure but the foundation and lower structure remain sound, we rebuild from the roofline up using matching brick and proper crown construction. This preserves the original character of San Anselmo’s period homes while eliminating the leak path.
Full Chimney Rebuild
For chimneys with compromised structural integrity, multiple flue breaches, or extensive mortar joint failure throughout, a full rebuild is the only safe path. We dismantle and reconstruct using proper footing support, reinforced crowns, and new stainless liners sized to the appliance. In San Anselmo’s fire-prone hillside zones, we also install spark-arrestor caps as part of the rebuild to meet wildland-urban interface requirements.

Trusted Brands We Service in San Anselmo
We do not use builder-grade substitutes. Our trucks carry DuraFlex stainless liners, HeatShield cerfractory sealant for resurfacing damaged flues, and Copperfield chimney caps and flashing components. For rebuilds, we source matching brick through Famco and Gelco distributors with Marin County yards. San Anselmo customers get the same professional-grade materials we use in San Francisco commercial jobs, and because we stock locally, turnaround is fast. If your chimney needs a part we do not have on the truck, we can usually source it within 24 hours.
Common Chimney Liner & Rebuild Problems We See in San Anselmo Homes
- Moisture-driven mortar joint failure. The Ross Valley’s 35+ inches of annual rainfall, delivered by Pacific storms pushed against the Marin hills, creates repeated wetting-and-drying cycles that degrade mortar far faster than in drier East Bay communities. We see this most severely on chimneys with failed or missing crowns.
- Cracked clay flue tiles from sustained moisture absorption. Original unrelined chimneys in San Anselmo’s 1905-1950 housing stock were built with clay tiles that absorb water, expand, and crack during freeze-thaw cycles or even just seasonal temperature shifts. Hairline cracks become gas leakage paths and structural weaknesses.
- Spalling brick faces from decades of rain exposure. The face of the brick flakes away, exposing the softer interior to further damage. This is cosmetic at first, but left untreated it compromises the chimney’s structural shell and allows water into the wall cavity.
- Northwest downdraft on hillside homes. Properties climbing toward the Marin open-space ridgeline experience direct wind exposure that can reverse chimney draft, pushing smoke into living spaces. These chimneys often need taller flue extensions, proper cap design, and sometimes stainless liners with improved insulation to maintain draw.
Pricing for Chimney Liner & Rebuild in San Anselmo, CA
Here is what chimney liner and rebuild work costs in the San Anselmo market:

FAQs - Chimney Liner & Rebuild in San Anselmo
San Anselmo sits in the Ross Valley, where Pacific storm systems are forced upward by encircling hills and deposit 35+ inches of rain annually directly over the town. This sustained moisture exposure, combined with a housing stock of 1910s-1940s homes with original unlined or poorly lined chimneys, makes mortar erosion and spalling brick the dominant failure modes here. In drier East Bay suburbs, creosote buildup from wood burning is typically the primary concern. For San Anselmo homeowners, moisture infiltration prevention is the central issue in any liner or rebuild decision. Call (855) 408-5567 and we’ll inspect yours at no charge.
Yes, and it is often the best solution for the taller, more exposed chimneys common in neighborhoods climbing toward the Marin open-space ridgeline. We use properly insulated DuraFlex stainless liners that maintain flue temperature and draft even under northwest wind pressure. The installation requires precise sizing and often a taller cap extension to combat downdraft. Our technicians have done this work on hillside homes throughout 94960 and 94979. Call (855) 408-5567 for an exact quote.
A partial rebuild addresses damage from the roofline upward, preserving the original lower structure when it remains sound. A full rebuild is necessary when moisture damage, foundation settling, or multiple flue breaches have compromised the chimney’s structural integrity throughout. In San Anselmo’s 1920s-1940s homes, we often find that what looks like a crown or upper-course problem has extended downward through freeze-thaw damage to the wythes separating flues. Our Level-2 camera inspection determines which path is appropriate. Call (855) 408-5567 for a free second opinion on any written estimate.
Yes, if your property abuts or is within the wildland-urban interface zone, a spark-arrestor cap is required for compliance with Marin County fire codes and is a practical necessity given the exposure to dry summer conditions and fire risk. We install Copperfield and Famco spark-arrestor caps as part of liner and rebuild packages for hillside homes. The cap also keeps rain out, which in San Anselmo’s climate is nearly as important as the spark protection. Call (855) 408-5567 to schedule installation.
We install and service DuraFlex, HeatShield, Olympia Chimney, and Copperfield products exclusively. We do not use generic or builder-grade substitutes. These are the same brands specified by commercial chimney professionals nationwide, and we stock them locally for fast turnaround on San Anselmo jobs. If your existing liner is from another manufacturer, we can evaluate its condition and replace it with a professional-grade system backed by our 90-Day Done Right Promise. Call (855) 408-5567 for an inspection.
