Why Hearthstone Chimney Co. of San Francisco Is Concord’s Preferred Chimney Repair Company
We’ve been answering calls from Concord homeowners for over 42 years. Warren Eckhart founded this company in 1984 with a straightforward principle: document what you find, explain it plainly, and stand behind the repair. That approach resonates in Concord, where residents have long memories for contractors who cut corners.
Our technicians know the difference between a masonry chimney on an older home near Todos Santos Plaza and the prefabricated zero-clearance units that dominate the ranch tracts off Treat Boulevard and Clayton Road. In Concord’s 94521 neighborhood, we replaced a corroded chase cover and repaired a cracked DuraFlex firebox on a 1972 zero-clearance unit. The homeowner, a self-reliant DIYer, appreciated our single-trip strategy - bringing heavy-duty parts like Gelco refractory panels to avoid delays.
Every inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, with no arguing. If it’s not right, we come back. That’s the Keystone Standard, and it’s how we’ve stayed in business since 1984.
Our Chimney Repair Services in Concord
Chimney Rebuilding
Concord’s 1960s-1970s tract homes in ZIPs 94518, 94519, and 94521 were fitted with prefabricated zero-clearance metal fireplaces rather than traditional masonry chimneys. At 40-60 years of age, these units frequently show cracked steel fireboxes, failed refractory panels, and corroded chase covers that a standard sweep will uncover. When the damage exceeds what spot repair can fix, we rebuild using professional-grade materials - HeatShield for resurfacing, DuraFlex for liner replacement, Gelco for refractory panels. Most rebuilding jobs in Concord are completed in a single visit because we stock the parts and measure before we arrive.
Flashing Repair
The junction where your chimney meets the roof is where water enters most often in Concord homes. Our flashing repair uses professional-grade materials from Copperfield and Famco, installed with the same attention to detail we’d use on our own homes. We see particular flashing deterioration on Concord’s older ranch-style homes where decades of thermal expansion have loosened the seal. Done right - and we stand behind it.
Spalling Brick Repair
While Concord’s dominant housing stock is zero-clearance metal fireplaces, masonry chimneys do exist on pre-war and early postwar homes near downtown and along Monument Boulevard. Spalling - bricks flaking and crumbling from moisture intrusion - accelerates in Concord’s climate because the Diablo winds create rapid wet-dry cycles. We remove damaged brick, repoint with matching mortar, and apply breathable waterproofing that lets the chimney shed moisture without trapping it inside.
Mortar Repointing & Tuckpointing
For Concord’s masonry chimneys, deteriorated mortar joints are an open invitation to water. Our repointing grinds out failed mortar to proper depth and replaces it with color-matched, weather-resistant mortar formulated for Bay Area temperature swings. Tuckpointing restores both structural integrity and appearance. We document the before condition with photos, explain what we found, and give you a fixed price before any work begins.
Chimney Waterproofing
Water is a chimney’s enemy everywhere, but Concord’s combination of winter rain and dry Diablo wind events creates unique stress. Waterproofing must breathe - trapping moisture inside accelerates spalling and steel corrosion. We use professional-grade breathable sealants from Olympia Chimney, applied after any necessary repairs, with a clear explanation of what we’re using and why.

Common Chimney Repair Problems We See in Concord Homes
- Cracked zero-clearance fireboxes from decades of thermal cycling. Concord’s factory-built metal fireplaces, now 40-60 years old, develop cracks in the steel firebox or refractory panels that go unnoticed until a Diablo wind-season fire risks ember escape. These cracks don’t heal themselves - they widen.
- Corroded chase covers on prefab fireplaces. The sheet-metal chase cover on top of Concord’s zero-clearance units rusts through, allowing water intrusion that rots surrounding framing and nullifies any waterproofing efforts below. We spot this on nearly every inspection of 1960s-1970s homes.
- Neglected pre-season inspections leaving dried creosote uncleaned. The first cold snap in Concord often arrives simultaneously with Diablo wind conditions - meaning an uncleaned chimney gets its inaugural fire of the year on the exact day fire-spread risk is highest. That timing is genuinely different from coastal Bay Area markets.
- Failed flashing where chimney meets roof. Years of sun and wind on Concord’s older homes loosen the seal, and the next rain finds its way into walls and ceilings. Caught early, it’s a flashing repair. Caught late, it’s reframing and drywall.

FAQs - Chimney Repair in Concord
Zero-clearance fireplaces have a designed lifespan of 20-30 years, and Concord’s dominant 1960s-1970s tract-home stock means most are now 40-60 years old. The steel fireboxes crack from repeated thermal cycling, refractory panels deteriorate, and chase covers corrode - none of which are issues on traditional masonry chimneys built from brick and mortar. These factory-built units were never intended to last half a century. Call (855) 408-5567 and we’ll inspect yours with a camera, show you the photos, and give you a straight answer on whether repair or replacement makes sense.
Diablo winds are dry, hot offshore gusts that roll through the Diablo Valley each October and November, dropping relative humidity sharply and increasing fire-spread risk. In Concord, this means we push hard on pre-season inspections in late September through early October - before the first cold snap and the first fire of the year coincide with dangerous wind conditions. If your chimney needs repair, completing it before Diablo wind season is genuinely urgent. We stock parts for Concord’s common zero-clearance models so most repairs finish in one visit. Call (855) 408-5567 to schedule before the winds arrive.
Yes - we replace corroded chase covers on Concord’s aging prefabricated fireplaces regularly, using Gelco and Copperfield components sized to your unit. The 1968-1975 ranch tracts in ZIPs 94518 and 94519 share common chase cover dimensions, and we often have the correct replacement in stock. A rusted chase cover is not a cosmetic issue; once water penetrates, it rots the surrounding framing and can require structural repair beyond the chimney itself. Call (855) 408-5567 for a free inspection - we’ll photograph the condition and give you a fixed price.
Not necessarily - many cracked zero-clearance fireboxes can be repaired with refractory panel replacement or DuraFlex firebox restoration, typically $600-$1,400 versus $3,500-$7,500+ for full rebuilding. The determining factor is crack location, depth, and whether the steel surround is compromised. We document everything with our Level-2 camera inspection, show you the photos, and explain your options plainly. Sometimes repair is sufficient. Sometimes replacement is the honest recommendation. Either way, you’ll know before any work begins. Call (855) 408-5567 for an exact assessment - estimates are free.
Concord experiences genuine winter cold - overnight lows regularly in the mid-30s°F - that drives sustained fireplace use unlike fog-belt Bay Area cities where fireplaces are largely decorative. A cracked firebox allows heat, sparks, and combustion gases to escape into wall cavities or framing, and when the first fire of the season coincides with October’s Diablo wind conditions, the risk of house fire is acute. We’ve seen cracked fireboxes in 94521 and 94520 that homeowners didn’t know existed until we showed them the camera footage. Don’t discover it the hard way. Call (855) 408-5567 - we’ll inspect, photograph, and repair before you need that first fire.
