Fast, Reliable Chimney Liner & Rebuild Across Redwood City
Chimney liner installation and chimney rebuilds in Redwood City typically cost between $1,800 and $6,500 depending on whether we’re retrofitting an unlined flue or reconstructing damaged masonry, and most jobs are completed in a single visit. If your home is in the older western neighborhoods of Redwood City - the 94061, 94062, or 94063 ZIP codes - there’s a strong chance your chimney was built during the postwar boom without a proper terra-cotta liner, which means creosote has been soaking into the brick for decades. We’re Chimney Liner & Rebuild in Redwood City specialists who understand this local housing stock, and we answer the phone with a live person 24 hours a day at (855) 408-5567.
We’ve been driving to Redwood City from San Francisco for over 42 years. We know the difference between a hillside home in Emerald Hills with foundation-settling cracks and a North Fair Oaks bungalow with an original unlined firebox. That local knowledge changes what we bring on the truck and how we quote the job.
Why Hearthstone Chimney Co. of San Francisco Is Redwood City’s Preferred Chimney Liner & Rebuild Company
Our reputation in Redwood City was built one chimney at a time, starting back in 1984. Homeowners in the 94061 and 94062 ZIP codes call us because we’ve documented the condition of their flues with Level-2 camera inspections, shown them the photos, and explained in plain English whether they need a liner, a rebuild, or both. No jargon, no scare tactics.
We typically arrive in Redwood City within 90 minutes of a scheduled appointment, and our background-checked, uniformed technicians carry the parts to complete most liner installations and partial rebuilds in a single visit. That’s not a slogan - it’s how we avoid sending a homeowner back to a cold house overnight.
Warren Eckhart, who leads Hearthstone Chimney Co., insists that every technician understands Redwood City’s specific conditions: the thermal pocket that keeps the Peninsula warmer than San Francisco, the postwar building practices that skipped flue liners in 94063, and the sloped-lot settling that cracks fireboxes in Emerald Hills. A technician who doesn’t know those local failure modes is guessing.
Our Chimney Liner & Rebuild Services in Redwood City
Stainless Steel Liner Installation
For most Redwood City homes with unlined or deteriorated masonry chimneys, a stainless steel liner is the right fix. We install DuraFlex and Olympia Chimney liners sized precisely to your appliance - wood fireplace, gas insert, or pellet stove. In the 94063 ZIP, where many chimneys were built without any liner at all, this is often the difference between a safe system and a structure fire waiting to happen. The liner creates a sealed, smooth-walled passage that contains creosote, carbon monoxide, and sparks, protecting the surrounding brick from heat transfer and saturation.
Flexible Liner Retrofits
Not every chimney in Redwood City runs straight. The offset flues in some Emerald Hills homes, shifted by decades of micro-settling, require a flexible liner that can navigate bends without creating snag points for creosote buildup. We measure the offset with our camera system before quoting, so you know exactly what the installation involves. Flexible liners from DuraFlex handle thermal expansion better than rigid pipe in these compromised structures.
Liner Replacement
Some Redwood City chimneys already have liners - terra-cotta from the 1960s or stainless steel from a previous retrofit - but they’ve cracked, separated at the joints, or corroded through. We extract the failed liner and install a new system, often upgrading the insulation and termination cap in the same visit. If your chimney was lined twenty years ago with a bargain product, replacement with a professional-grade liner from Copperfield or Famco restores both safety and efficiency.
Partial Chimney Rebuild
When the masonry itself has failed - spalled brick, deteriorated mortar joints, or a crown that’s cracked and funneling water into the structure - a liner alone won’t solve the problem. Our partial rebuilds address the firebox, smoke chamber, or upper stack while preserving sound masonry below. In Redwood City’s older neighborhoods, we regularly perform partial rebuilds on chimneys where the original builder used single-wythe construction and no liner, meaning the brick has been absorbing creosote and moisture for sixty-plus years. We rebuild with proper materials and install a new liner as part of the system.
Full Chimney Rebuild
Occasionally we encounter a chimney in Redwood City - usually in the 94063 corridor - where the masonry is too far gone for partial repair. The brick is crumbly throughout, the footing has shifted, or previous patch jobs have created more problems than they solved. A full rebuild dismantles the chimney to the roofline (or below, if the firebox is involved) and reconstructs it to current California Building Code standards, including a proper liner, crown, and cap. We quote these jobs with no-hassle upfront pricing: the number on the estimate is the number on the invoice.
Liner Repair
Not every damaged liner needs full replacement. Localized cracks in a stainless steel liner, failed sealant at the top plate, or a disconnected collar can sometimes be repaired. We determine this with our camera inspection - photos you can see, a plain-English verdict - and we won’t sell you a full replacement if a repair is the honest answer.

Trusted Brands We Service in Redwood City
We stock DuraFlex flexible liners and Copperfield termination components on our Redwood City trucks, which means most installations don’t wait on parts. For rigid stainless systems, we specify Olympia Chimney and Famco components - brands that publish their testing data and stand behind their products. We don’t use builder-grade substitutes. The difference shows up ten years later, when a cheap liner has corroded through and a DuraFlex or Olympia system is still doing its job. That’s why our 90-Day Done Right Promise covers the installation and the materials: if it’s not right, we come back, in writing, no arguing.
Common Chimney Liner & Rebuild Problems We See in Redwood City Homes
- Unlined brick chimneys in 94063 saturated with creosote. In North Fair Oaks and east Redwood City, postwar bungalows were built with single-wythe brick chimneys and no terra-cotta liner. Creosote soaks directly into the porous brick, and standard sweeping can’t remove it. The only safe solution is a full stainless steel liner installation.
- Cracked terra-cotta flue tiles in Emerald Hills from foundation settling. Homes on sloped lots in 94062 experience micro-movement that cracks flue tiles and offsets their alignment. Smoke leaks into the chimney wall, and carbon monoxide can enter living spaces. Camera inspection reveals the extent before we quote a liner replacement or partial rebuild.
- Uncapped gas-insert flues deteriorating from moisture and pest ingress. Redwood City’s warmer climate means converted fireplaces often sit unused for months, but an uncapped flue lets rain and animals in. We’ve pulled nests and standing water from flues that the homeowner assumed were “closed up” because the gas insert was installed.
- Crown and mortar failure from thermal cycling. Redwood City’s sunny days and cool evenings create expansion and contraction stress on chimney crowns. Cracked crowns funnel water into the structure, accelerating freeze-thaw damage to mortar and liner supports. We repair or pour new crowns as part of liner and rebuild work.

FAQs - Chimney Liner & Rebuild in Redwood City
Yes, and in most cases it’s the right solution. We install a stainless steel or flexible liner sized to your fireplace, seal the top with a proper termination, and inspect the crown and cap for integrity. On a bungalow in North Fair Oaks (94063), our crew opened a single-wythe brick chimney that had never been lined. The original firebox was so saturated with creosote that we could scrape it off the exposed brick with a trowel. We installed a DuraFlex stainless steel liner, sealed the crown, and capped the flue - transforming a decades-old fire hazard into a safe, code-compliant system. Call (855) 408-5567 for a free inspection and exact quote.
Smoke seeping through mortar joints usually means cracked or offset flue tiles, often caused by foundation micro-settling on sloped lots. The flue gases are finding paths through the chimney wall instead of exiting at the top. This is a carbon monoxide risk and a fire hazard. We diagnose it with a Level-2 camera inspection - photos you can see, a plain-English verdict - and we typically recommend either liner replacement or partial rebuild depending on the masonry condition. Call (855) 408-5567; we’ll be there when we say.
It is. An uncapped flue lets rain, debris, and animals into the chimney, and in Redwood City’s climate that moisture accelerates deterioration of any remaining liner or masonry. We’ve found standing water and nesting material in converted flues that homeowners assumed were sealed. The fix is straightforward: inspect with a camera, clean and assess, then install a proper cap and verify venting. Call (855) 408-5567 for a free second opinion if another company quoted you work you’re unsure about.
The masonry tells the story. If the brick is sound, the mortar joints are tight, and the crown is intact, a liner replacement or installation solves the problem. If the brick is spalling, the mortar is powdery, or the crown has failed and water has saturated the structure, a partial or full rebuild is necessary. We document everything with photos during our inspection and explain what we see. No pressure, no upsell - a square deal. Call (855) 408-5567 to schedule.
We do, though demand is lighter. Redwood Shores was built from the 1980s onward on reclaimed baylands, and most housing is gas-only condos and townhomes with direct-vent systems rather than traditional masonry chimneys. When Redwood Shores residents call us, it’s usually for gas fireplace service, venting inspections, or occasional chimney cap work on the few wood-burning units. We’re happy to come out, and we’ll tell you honestly if your system needs attention or if it’s fine as-is. Call (855) 408-5567.
