Why Hearthstone Chimney Co. of San Francisco Is Fairfax’s Preferred Fireplace Services Company
We’ve been serving Marin County homeowners for over 42 years, and Fairfax has always been a town we know street by street. Our Fireplace Services in Fairfax reputation was built on showing up when we say, documenting every inspection with photos our customers can see, and explaining the verdict in plain English - no jargon, no upsell.
Fairfax customers call us back because we understand their houses. The 1920s bungalows on Elsie Lane, the hillside cabins off Cascade Canyon Road, the cottages near Peri Park - we’ve worked on chimneys in all of them. We know which ones have original clay-tile liners too small for modern inserts, which ones face wind-driven rain from the west, and which back up to open space where a single spark is a serious risk.
Our response time to Fairfax is typically same-day or next-day for non-emergency calls, and we carry the parts and materials to complete most repairs in one visit. That’s not a promise every company can keep in a canyon town with narrow roads and limited parking - but we’ve been doing it since 1984.
Every job is backed by our 90-Day Done Right Promise, in writing with no arguing. Warren Eckhart has stood behind that guarantee since founding this company, and we still answer the phone with a live person, 24/7.
Our Fireplace Services in Fairfax
Wood Burning Fireplace Service
Fairfax’s wet winters - often 40-plus inches of rain - drive homeowners to burn wood for heat more frequently than in drier parts of Marin. That heavier use accelerates creosote buildup in flues that may not have been swept in years, especially in the older homes common here. Our wood burning fireplace service includes a Level-2 camera inspection, full flue cleaning, and a documented verdict with photos you can see. We pay particular attention to spark arrestor condition, which is not optional in Fairfax’s CAL FIRE High Fire Hazard Severity Zone.
Gas Fireplace Service
Many Fairfax homeowners switched to gas to avoid Spare the Air restrictions, but gas fireplaces still need annual service - burner ports clog, pilot assemblies drift, and venting requires inspection. We service standing-pilot and electronic-ignition units, check gas pressure and combustion, and verify that venting is clear and correctly configured for your home’s layout.
Fireplace Insert Installation & Service
Inserts are a popular upgrade in Fairfax’s 1920s-1950s housing stock, but original masonry chimneys were rarely designed for them. We frequently find unlined or improperly sized flues from inserts added in the 1970s and 1980s, creating dangerous drafting problems and creosote accumulation. Our Fireplace Services team installs DuraFlex stainless steel liners sized precisely for your insert, with proper insulation and termination to meet current standards.
Fireplace Conversion
Converting a wood-burning fireplace to gas in Fairfax requires attention to local code, venting configuration, and the condition of your existing chimney. We handle the full conversion - gas line coordination, burner and log set selection, venting assessment, and final inspection readiness. For homes in the High Fire Hazard Severity Zone, conversion can eliminate the spark-risk of open wood burning while preserving the hearth.
Damper Repair
A stuck or rusted damper wastes heat and can allow down-drafts of cold canyon air. We repair or replace throat and top-sealing dampers, including lock-top models that double as spark arrestors - a practical upgrade in Fairfax’s fire-risk environment.
Firebox Repair
Cracked or deteriorated firebox panels let heat reach combustible framing. We repair with refractory materials rated for the application, or recommend replacement when damage is extensive. In Fairfax’s older homes, we often find fireboxes that have seen decades of use without proper maintenance.
Trusted Brands We Service in Fairfax
We work exclusively with professional-grade materials - no builder-grade substitutes. For Fairfax’s demanding conditions, we specify DuraFlex stainless steel liners for corrosion resistance against salt air and heavy rain, HeatShield refractory mortar for crown and firebox repairs, and Famco and Copperfield components for caps, dampers, and spark arrestors. We stock common parts for faster turnaround on Fairfax calls, so we’re not ordering and making you wait.
Common Fireplace Services Problems We See in Fairfax Homes
- Crushed or missing spark arrestors. Coastal salt air corrodes arrestor screens faster than inland, and in Fairfax’s High Fire Hazard Severity Zone, a compromised arrestor is both a code violation and a life-safety issue. We find this most often on homes backing to Cascade Canyon or the White Hill ridgeline.
- Moisture-damaged chimney crowns and spalling masonry. Fairfax’s orographic rainfall - 40-plus inches annually - drives water into aging mortar with more aggression than in drier towns like San Rafael. Spalling crowns and deteriorated flashing are routine findings.
- Unlined or improperly sized flues from vintage inserts. Wood stoves and inserts added in the 1970s and 1980s often went in without proper relining, leaving flues too large or too damaged for safe operation. Creosote builds up dangerously, and drafting suffers.
- Accelerated hardware corrosion from salt-laden canyon air. Even inland from the coast, Fairfax’s canyon geography channels marine air that corrodes caps, dampers, and fasteners years faster than expected.
We serviced a 1940s cabin on Cascade Canyon Road whose clay-tile chimney had a crushed spark arrestor and spalling crown from years of rain and salt air. We installed a new DuraFlex stainless liner, a FastCap arrestor, and tuckpointed the crown using HeatShield mortar. The next Spare the Air burn day, the owner had a safe, code-compliant fire.

FAQs - Fireplace Services in Fairfax
Yes - it is required by code and by CAL FIRE for all properties in Fairfax’s High Fire Hazard Severity Zone. A properly sized and secured spark arrestor prevents embers from escaping onto the chaparral and redwood-duff hillsides surrounding town. We inspect arrestors on every service call and replace corroded or missing units with code-compliant screens. Call (855) 408-5567 to schedule - estimates are free.
Annually at minimum, and possibly more often if you burn wood as primary heat during the rainy season. Fairfax’s 40-plus inches of annual rainfall combined with heavier winter burning accelerates creosote accumulation and moisture damage. The National Fire Protection Association recommends annual inspection; in Fairfax’s conditions, that schedule is not conservative - it’s necessary. Call (855) 408-5567 to book your $89 seasonal tune-up.
Yes, and many homeowners do to avoid Spare the Air restrictions and eliminate spark risk in the High Fire Hazard Severity Zone. Conversion requires proper venting assessment, gas line coordination, and compliance with local code. We handle the complete job and provide documentation for your records. Call (855) 408-5567 for a free evaluation of your existing fireplace.
Fairfax’s heavy orographic rainfall and temperature cycling between wet winters and dry summers stress concrete crowns aggressively. Salt-laden air from the coast accelerates corrosion of reinforcing and spalling of the surface. We rebuild crowns with HeatShield refractory mortar and proper overhang and drip edges to shed water - done right, and we stand behind it with our 90-Day Done Right Promise.
We typically specify DuraFlex stainless steel liners for Fairfax’s conditions - the alloy resists corrosion from salt air and heavy moisture better than standard grades, and the flexible design accommodates the offsets common in older masonry chimneys. Sizing is critical and depends on your appliance; we measure and specify precisely rather than guessing. Call (855) 408-5567 for an exact recommendation based on your chimney.
