We’ve earned that trust by documenting every inspection with photos homeowners can see and delivering a plain-English verdict, not a hard sell.
Our response time to Kensington is typically same-day or next-day, depending on where you’re located in the 94530 zip code.

The 90-Day Done Right Promise backs every job in writing - if it’s not right, we come back, no paperwork, no arguing. That’s been our standard since 1984, and it’s why Kensington customers who’ve been burned by contractors before tend to stay with us.
Our Chimney Liner & Rebuild Services in Kensington
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Kensington homes with cracked or missing clay-tile flues. We install DuraFlex and Olympia Chimney liners rated for the temperature cycles of wood-burning fireplaces common in 1920s-1950s homes here. The marine fog that rolls through Kensington’s hills keeps old flues damp year-round, which accelerates corrosion in inferior materials. Our stainless installations carry a lifetime warranty on the liner itself, and we size them precisely for your chimney’s interior dimensions - an important step on the offset flues we often find in these older masonry structures.

Flexible Liner Solutions
Not every Kensington chimney has a straight shot from firebox to crown. The offset flues in many Colonial Revivals and bungalows here require a flexible liner that can navigate bends without creating draft-killing ridges. We use professional-grade flexible products from Famco and DuraFlex, installed with proper insulation to meet current clearances. On a recent job near Arlington Avenue, a flexible liner was the only way to restore safe venting without tearing into finished interior walls. The homeowner had heat again by evening.

Liner Replacement
Full liner replacement becomes necessary when clay tiles have shifted, cracked, or deteriorated to the point that gaps allow combustion gases into the chimney walls. In Kensington, we see this condition more frequently than in inland cities because decades of moisture cycling through fog-dampened flues attack the tiles from both sides. Our liner replacement process includes a Level-2 camera inspection before and after, so you see exactly what failed and exactly what we fixed. Photos you can see, a plain-English verdict - that’s how we work.

Partial Rebuild
Many of Kensington’s exterior chimneys on southwest-facing walls need partial rebuilds of the upper courses, crown, or firebox while the lower structure remains sound. The prevailing onshore wind loads this side with salt-laden moisture, and we’ve found mortar erosion running two or three repointing cycles ahead of the sheltered northeast face. We rebuild with matching brick and proper crown slope to shed water, using techniques that respect the original construction while bringing the chimney up to post-1991 fire-era standards. A square deal: no surprises on the bill.

Full Chimney Rebuild
When a Kensington chimney has suffered catastrophic settling, extensive spalling, or multiple structural failures, a full rebuild is the only safe option. We dismantle and reconstruct using proper footing support, reinforced wythes, and modern clearances - critical on these hillside lots where seismic movement and soil conditions add stress. Every full rebuild includes a new stainless steel liner from DuraFlex or Olympia Chimney, properly sized and insulated. We’ll be there when we say, and we stand behind the result.

Liner Repair
Some Kensington chimneys don’t need full replacement - localized cracks or minor offsets can be addressed with HeatShield cerfractory sealant or targeted tile replacement. We only recommend repair when we’re certain it restores safe, code-compliant venting. Our Level-2 inspection determines which path is right for your chimney, documented with photos and explained in plain English before you decide.

Trusted Brands We Service in Kensington
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Kensington customers, this means we stock the liners, caps, and repair components that fit the 5⅝” × 9⅝” and 8″ × 8″ flue dimensions common in local homes, so we’re not ordering parts and making you wait. Most jobs finish in one visit because our trucks carry what these chimneys actually need. Done right, and we stand behind it.
Common Chimney Liner & Rebuild Problems We See in Kensington Homes
- Corroded clay-tile liners from decades of moisture cycling. Kensington’s marine fog keeps flues damp year-round, and old lime-based mortar joints absorb that moisture repeatedly. The result is cracked, offset, or missing tiles that allow combustion gases to leak into chimney walls - a condition we find on first-of-season calls when the homeowner lights a fire and smells smoke in the room.
- Southwest-facing mortar erosion on exterior chimneys. Many Craftsman and Tudor homes here have chimneys built on the Bay-facing wall, which takes the full brunt of fog-laden onshore wind. We inspect this face first on every Kensington call, because the mortar deterioration is often severe while the sheltered side looks nearly untouched.
- Poor draft from moisture-laden flues. Infrequently used fireplaces in Kensington’s damp climate develop flues that never fully dry out. The first fire of the season smokes back into the room, and homeowners often blame the damper or the firewood before a liner inspection reveals the real problem: a flue lined with condensation and creosote that blocks proper airflow.
- Spalled brick and crown failure from salt-laden fog. The same marine layer that keeps Kensington green also attacks chimney crowns and brick faces. We regularly see crowns cracked or completely detached, with water infiltrating the chimney structure below. Left unaddressed, this leads to the kind of comprehensive rebuild that costs significantly more than preventive crown replacement.

FAQs - Chimney Liner & Rebuild in Kensington
Kensington’s hillside position in the direct path of marine fog creates sustained moisture cycling that El Cerrito’s flatter, more sheltered terrain doesn’t replicate to the same degree. The fog keeps flues damp for longer periods, accelerating clay-tile deterioration and creosote buildup that compromise liner integrity faster than in less exposed locations. If your Kensington home has an original unlined or clay-tile flue, the risk of hidden damage is substantially higher. Call (855) 408-5567 and we’ll inspect it with a camera - estimates are free.
Every year before the first fire, without exception. The 1920s-1950s masonry chimneys that define Kensington’s housing stock were built before modern liner requirements, and their original clay tiles have endured decades of our damp climate. An annual Level-2 inspection with camera documentation catches cracks and offsets before they become safety hazards, especially critical in a community this fire-conscious. We schedule these inspections throughout late summer and fall - call (855) 408-5567 to reserve your slot.
Yes, and we’ve done many. The key is designing the rebuild to withstand that exposure - proper crown overhang and slope, quality mortar with appropriate Portland cement content for moisture resistance, and in some cases a chimney cap from Gelco or Famco that deflects wind-driven rain. We always inspect the Bay-facing mortar face first on these jobs, because the damage pattern is predictable and we plan the rebuild accordingly. On a Kensington Tudor Revival near the Berkeley border, we replaced a cracked clay-tile liner with a DuraFlex stainless steel liner and rebuilt the crown after salt-laden fog had spalled the original brickwork. The homeowner noted improved draft before fire season.
Kensington follows Contra Costa County fire codes, which do not mandate retroactive liner upgrades on existing chimneys but do require that any chimney used for solid-fuel burning maintain a sound, continuous flue without cracks or gaps that could emit sparks or gases. In practice, this means most original clay-tile liners in Kensington’s older homes no longer comply once deterioration is documented. Our inspection reports note code compliance status in plain English, and we explain what upgrade path meets current standards. Call (855) 408-5567 for a documented assessment.
We install DuraFlex and Olympia Chimney stainless steel liners, with Famco and Copperfield components for caps, dampers, and connectors as needed. These are professional-grade products, not the thin-gauge substitutes some operators use. For localized repairs, we use HeatShield cerfractory sealant. We stock the common sizes for Kensington’s 5⅝” × 9⅝” and 8″ × 8″ flues, so most installations complete in one visit. Ask about our 90-Day Done Right Promise in writing - if it’s not right, we make it right, no arguing.
