Why Hearthstone Chimney Co. of San Francisco Is Concord’s Preferred Chimney Liner & Rebuild Company
We’ve been serving Contra Costa County for over 42 years, and Concord has always been a core part of our route. Warren Eckhart founded this company in 1984 with a straightforward idea: document what you find, explain it in plain English, and stand behind the work. That approach resonates with Concord homeowners, many of whom have lived in the same house since the 1970s or 1980s and have no patience for contractors who disappear after the check clears.
Our technicians are background-checked, uniformed, and carry Level-2 camera equipment on every truck. We end every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics. If we find a cracked firebox in a Concord home near Ygnacio Valley Road, we show you the crack, explain the heat-transfer risk, and give you a written estimate with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Response time to Concord is typically same-day or next-day, and most liner replacements and partial rebuilds are completed in a single visit. We don’t subcontract to random crews. Our people know the difference between a Gelco chase cover and a Famco termination cap, and they know which one your Concord neighborhood likely needs based on the builder and the decade.

Our Chimney Liner & Rebuild Services in Concord
Stainless Steel Liner Installation
Concord’s 94518 and 94519 ZIP codes contain a high concentration of ranch-style tract homes built with zero-clearance metal fireplaces, now 40-60 years old. These units were never designed to last half a century. Cracked steel fireboxes, failed refractory panels, and corroded chase covers are routine findings on our Level-2 inspections. A stainless steel liner from DuraFlex or Olympia Chimney gives these aging systems a new, code-compliant venting path that handles the sustained winter use Concord actually sees. Unlike fog-belt cities where fireplaces are decorative, Concord gets cold enough to run fires nightly from November through March. That real use demands real protection.
Flexible Liner Systems
Flexible liners work well for many Concord masonry chimneys with offsets or bends, but they’re not universal. In detached workshops and accessory buildings common on Concord’s larger lots, long horizontal runs and oversized venting requirements can cause flexible liners to collapse under excessive draft. We assess the run length, appliance BTU output, and clearance requirements before recommending any system. Sometimes a rigid stainless steel section combined with a short flexible connector is the right call. We don’t guess. We measure, we photograph, and we specify.
Liner Replacement
When an existing clay tile liner has spalled, cracked, or shifted, replacement is the only safe option. In Concord’s older homes near Treat Boulevard or the Concord Boulevard corridor, we’ve found clay liners damaged by decades of thermal cycling, minor seismic movement, and, in some cases, previous chimney fires the homeowner never knew occurred. Our liner replacement process includes a full camera inspection of the flue, removal of damaged sections, and installation of a new stainless steel or HeatShield-relined system sized precisely for your appliance. Most liner replacements in Concord are completed in one day.
Partial and Full Chimney Rebuild
We recently handled a full chimney rebuild in Concord’s 94521 neighborhood, replacing a cracked DuraSteel firebox and corroded chase cover with a new DuraFlex stainless steel liner system. The homeowner had been worried about insulation gaps causing heat transfer to nearby framing, but we sealed everything with HeatShield’s refractory patch, restoring safe clearance in one trip. Full rebuilds on Concord’s ranch homes require care with roof penetrations, especially on low-slope 1960s roofs with minimal overhang. Our crews use proper staging and protective decking to prevent shingle damage. Partial rebuilds, limited to the firebox, smoke chamber, or chase, are more common and typically cost less than half of a full rebuild.

Trusted Brands We Service in Concord
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Concord customers, this means we stock common chase covers, termination caps, and liner sections on our trucks, so we’re not waiting on a parts run to Walnut Creek while your chimney sits open. A Gelco stainless steel chase cover in the right profile for your Concord tract home’s factory-built fireplace. HeatShield refractory mortar for sealing gaps that camera inspections reveal. Olympia Chimney rigid liner sections for the straight runs common in Concord’s simpler flue designs. We order the odd sizes when needed, but most Concord jobs move fast because we’ve seen your chimney before and we came prepared.
Common Chimney Liner & Rebuild Problems We See in Concord Homes
- Cracked zero-clearance fireboxes in 94518 and 94519. The metal shells of these 40-60-year-old factory-built units fatigue and crack at weld seams. A cracked firebox can allow combustion gases to reach surrounding framing. We find this almost weekly in Concord’s older ranch tracts.
- Corroded chase covers and water intrusion. Concord’s hot, dry summers followed by occasional winter rains cause galvanized steel chase covers to rust through at the center seam. Water stains on the ceiling near the fireplace are often the first sign. We replace with Gelco or Famco stainless steel covers that outlast the original by decades.
- DIY liner repairs with dangerous gaps. Self-reliant homeowners in Concord’s acreage properties sometimes attempt partial liner repairs without proper sealing, leaving gaps that allow carbon monoxide seepage into living spaces. We document these with our Level-2 camera and explain why a proper replacement is the only safe fix.
- Diablo wind season creosote hazards. The Diablo wind events that roll through the Diablo Valley each October and November drop relative humidity sharply and send dry offshore gusts across Concord. An uncleaned chimney gets its first fire of the year on the exact day fire-spread risk is highest. Pre-season inspections are critical here in ways they simply aren’t in Oakland or Berkeley.

FAQs - Chimney Liner & Rebuild in Concord
Zero-clearance metal fireplaces have a rated lifespan of 20-30 years, and Concord’s dominant housing stock was built in the 1960s-1970s. At 40-60 years old, the steel fireboxes crack, refractory panels fail, and the original lightweight liners deteriorate. Masonry chimneys with clay tile liners can last longer but still suffer spalling and thermal damage. The factory-built units simply weren’t engineered for this many heating seasons. Call (855) 408-5567 for a camera inspection if your Concord home has its original metal fireplace.
Carbon monoxide infiltration and chimney fire are the two immediate risks. Diablo winds in October and November dry and loosen accumulated creosote, and the first cold snap drives Concord residents to light fires precisely when fire-spread conditions are worst. A compromised liner can’t contain combustion gases or contain a chimney fire. We push hard on pre-season inspections in late September for exactly this reason. Call (855) 408-5567 to schedule before the winds arrive.
Standard flexible liners often collapse or sag in long horizontal runs with high draft requirements, which is common in detached workshops on Concord’s larger lots. We typically specify rigid stainless steel sections or a hybrid system with minimal flexible connectors, sized to the appliance’s BTU output and the run’s total length. Every installation requires proper clearance to combustibles. Call (855) 408-5567 and we’ll measure your setup and give you a spec that works.
We use protective decking and proper staging, especially on low-slope 1960s roofs with minimal overhang that are common in Concord’s ranch tracts. Our crews document the existing roof condition with photos before we start, and we replace any disturbed shingles or flashing with matching materials. The chimney chase is rebuilt with proper weatherproofing integrated into the roof system. Most full rebuilds take two to three days. Call (855) 408-5567 for a written estimate and timeline.
A HeatShield patch resurfaces an existing clay tile liner or smoke chamber with a specialized refractory mortar, suitable for minor spalling, small cracks, or gaps at tile joints. It costs less and preserves the original flue dimensions. A full liner replacement installs a new stainless steel sleeve inside the chimney, necessary when tiles are extensively damaged, shifted, or missing entirely. In Concord’s climate with real sustained winter use, we only recommend HeatShield for defects covering less than roughly 30% of the flue surface. Anything more, and the thermal cycling will outpace the repair. Call (855) 408-5567 for a camera inspection and we’ll show you exactly what your flue looks like.
