Why Hearthstone Chimney Co. of San Francisco Is Lafayette’s Preferred Chimney Repair Company
We’ve been serving East Bay communities for over 42 years, and Lafayette homeowners have been calling us long enough that we know which hillside streets require four-wheel-drive access and which 1960s ranch plans hide double flues behind a single chimney breast. Warren Eckhart founded this company in 1984 on the principle that a craftsman doesn’t need to oversell - the work speaks, and the guarantee backs it.
Our technicians are background-checked, uniformed, and carry professional-grade materials from Olympia Chimney, Famco, and DuraFlex on every truck. That means when we arrive at a Lafayette home, we can repoint mortar, replace a spark arrestor, or reline a flue without scheduling a second trip for parts. Most jobs finish in one visit. The price we quote is the price on the invoice - a square deal, no surprises on the bill.
Our 90-Day Done Right Promise applies to every Lafayette repair: if it’s not right, we come back, in writing, no arguing. We’ve operated this way since 1984 because we plan to be here in thirty more years, and that only works if neighbors trust us.
Our Chimney Repair Services in Lafayette
Mortar Repointing and Tuckpointing
Lafayette’s inland position in the Lamorinda valley delivers colder winters than Bay-facing cities, with regular overnight lows in the 30s. That freeze-thaw cycle attacks mortar joints on hillside chimneys year after year. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar that bonds correctly with existing masonry. For homes along upper Reliez Valley Road and similar exposures, we also assess whether the chimney crown needs rebuilding to stop water intrusion at the source.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is common on Lafayette chimneys that have endured decades of moisture penetration followed by freezing. Once the brick face pops off, the interior structure absorbs water faster. We remove damaged brick, source matching replacements where possible, and rebuild the affected courses with proper weatherproofing. On older hillside homes with original 1950s-1970s masonry, this repair often reveals the need for concurrent crown work, which we can handle in the same visit.

Chimney Waterproofing
Lafayette’s dry Diablo wind season creates a false sense of security about moisture, but driving fall rains hit exposed chimney masonry directly. We apply professional-grade breathable waterproofing agents that allow vapor to escape while blocking liquid water. This is particularly important for Burton Valley properties with multiple fireplaces where chimney mass is substantial and replacement costs would be significant. Waterproofing extends the life of sound mortar and brick by years.

Flashing Repair
The intersection where chimney meets roof is a common leak point on Lafayette’s ranch-style homes, many of which have seen multiple roof overlays without proper flashing updates. We remove corroded or improperly stepped flashing and install new galvanized or copper flashing with proper counterflashing integration into the masonry. On steeper hillside lots where roof access is challenging, our crews bring the appropriate safety equipment and never improvise.

HeatShield Liner Installation
Original clay flue liners in Lafayette’s 1950s-1970s housing stock crack from thermal cycling and creosote accumulation, creating fire and carbon monoxide hazards. We install HeatShield cerampolymer liner systems that restore flue integrity without full chimney rebuilding. This is often the right solution for double-flue ranch homes where both fireplaces need attention. The cerampolymer withstands Lafayette’s heavy burning seasons and meets all applicable fire codes.

Spark Arrestor Replacement and Code-Compliance Cap Installation
This is not optional in Lafayette. California Fire Code mandates spark arrestors on all chimneys within the Very High Fire Hazard Severity Zone, and Contra Costa County Fire Protection District defensible-space inspections enforce it. We install DuraFlex spark arrestor caps that meet VHFHSZ requirements, properly sized to your flue with stainless steel construction that survives the East Bay hills’ exposure. A missing or deteriorated cap here is a code violation, not merely a maintenance item.

Trusted Brands We Service in Lafayette
We stock professional-grade materials from Olympia Chimney, Famco, and DuraFlex on every service vehicle, which means Lafayette customers don’t wait for parts orders from distant warehouses. When a spark arrestor rusts through after winter or a liner fails inspection, we replace it with the same brand the manufacturer specifies, not a generic substitute. HeatShield cerampolymer liners for firebox restoration, DuraFlex caps for VHFHSZ compliance, Famco termination fittings - these are the products we trust on our own homes, and they’re what we bring to yours.
Common Chimney Repair Problems We See in Lafayette Homes
- Failed spark arrestors triggering fire district citations. Contra Costa County Fire Protection District defensible-space inspections each fall routinely flag uncapped or deteriorated chimneys in Lafayette’s hillside neighborhoods. Homeowners receive correction notices, and insurance non-renewal has followed in some cases. We replace corroded caps with code-compliant DuraFlex arrestors before inspection season.
- Cracked clay flue liners in never-relined 1960s ranches. The original clay tile in Burton Valley and Reliez Valley homes has often carried four decades of creosote. Thermal expansion cracks the tile, and creosote seeps behind it. HeatShield cerampolymer relining restores a smooth, sealed flue surface without tearing down the chimney.
- Spalling brick from freeze-thaw damage on exposed hillside chimneys. Chimneys on north-facing slopes or above the fog line take the worst of Lafayette’s cold nights. Water enters hairline cracks, freezes by morning, and pops brick faces loose. Tuckpointing and selective brick replacement stops the decay before structural rebuilding becomes necessary.
- Improper prior repairs failing within seasons. We’ve found builder-grade mortar slapped over deteriorated joints, incompatible sealants trapping moisture, and spark arrestors installed without proper screen mesh for VHFHSZ compliance. These shortcuts cost more to undo than to do correctly the first time.

FAQs - Chimney Repair in Lafayette
California Fire Code mandates spark arrestors on all chimneys within Very High Fire Hazard Severity Zones regardless of use frequency, and Lafayette sits entirely within such a zone. Embers from neighboring properties or distant wildfires can enter an uncapped flue and ignite accumulated creosote or debris. Contra Costa County Fire Protection District enforces this during fall defensible-space inspections. We install VHFHSZ-compliant DuraFlex spark arrestors sized to your flue - call (855) 408-5567 for a free inspection and exact quote.
Yes. We recently re-lined a double-flue masonry fireplace in a 1960s ranch home on Reliez Valley Road where decades of creosote had eaten away the original clay tile liner. The homeowner wanted it fixed in one trip to avoid scheduling around Diablo winds, so we installed a HeatShield cerampolymer liner system on both flues and replaced the corroded DuraFlex spark arrestor caps to meet VHFHSZ code - all while the crew navigated the long, steep driveway with heavy spring-loaded doors on the detached workshop. Most multi-flue Lafayette jobs complete in a single day. Call (855) 408-5567 to schedule.
Yes, when we perform the work. We design every spark arrestor installation, liner replacement, and cap repair to satisfy California Fire Code requirements for VHFHSZ properties and Contra Costa County Fire Protection District defensible-space protocols. We document our work with photos you can present to inspectors. If any repair falls short of code, our 90-Day Done Right Promise covers correction at no charge - in writing, no arguing. Call (855) 408-5567 before your scheduled inspection to ensure compliance.
We install DuraFlex stainless steel spark arrestor caps for Lafayette’s exposure. The marine-grade stainless construction resists the corrosion that destroys lesser caps in two to three seasons of East Bay hills moisture and temperature swing. DuraFlex also manufactures to exact flue dimensions, which matters for VHFHSZ compliance - an ill-fitting cap fails inspection regardless of material quality. We stock common sizes and can order same-day for less common flue dimensions. Call (855) 408-5567 for sizing and pricing.
It can. Several Lafayette homeowners have reported insurance non-renewal notices citing uncapped chimneys as defensible-space violations following Contra Costa County Fire Protection District inspections. An uncapped or non-compliant chimney in a VHFHSZ represents documented ignition liability that underwriters increasingly refuse to carry. We replace failed caps with code-compliant arrestors and provide written documentation of the work for your insurance file. Call (855) 408-5567 - estimates are free, and fall inspection season approaches quickly.
