Fast, Reliable Fireplace Services Across Hillsborough
Fireplace service in Hillsborough typically runs $180-$650 per unit depending on the work needed, and most multi-flue estate jobs are completed in a single scheduled visit. We’re Hearthstone Chimney Co. of San Francisco, and we’ve been driving out to Hillsborough since 1984 to service the Peninsula’s most distinctive housing stock. Our technicians are background-checked, uniformed, and carry the parts to finish the job without a return trip. Call (855) 408-5567 any hour - a live person answers, every time.
Hillsborough isn’t like neighboring Burlingame or San Mateo. This town legally prohibits all commercial and multi-family properties, which means every chimney we touch sits on a large private estate. These homes, predominantly built between the 1920s and 1950s in Tudor Revival, Spanish Colonial, and Mediterranean styles, routinely contain two to four original masonry fireplaces. A technician here is almost never servicing a single flue. Multi-stack, multi-flue diagnostics on 70-to-100-year-old brick chimneys are our standard call, not a specialty request.
That matters for how we work. We schedule longer appointments. We bring more equipment. And we document every flue with Level-2 camera inspections that end with photos you can see and a plain-English verdict. No guesswork. No shortcuts. The mortar earns its bond.

Our Fireplace Services in Hillsborough
Gas Fireplace Service
Many Hillsborough homeowners have converted original wood-burning hearths to gas for convenience and air-quality compliance. We service pilot assemblies, thermopiles, and smart-touch controls, including integration with existing home automation systems. On a recent call near the Country Club neighborhood, we diagnosed a failed valve on a 1930s fireplace that had been retrofitted with modern gas logs. The repair required a custom-fitted Olympia Chimney connector and careful calibration to preserve the original firebox dimensions. Gas fireplace service in Hillsborough typically runs $180-$340.
Wood Burning Fireplace
The Peninsula’s mild climate creates a paradox for Hillsborough’s ceremonial fireplaces. Low, smoldering decorative fires deposit proportionally heavy creosote per burn hour. Infrequent use isn’t a safety benefit; it’s a hidden hazard. We see third-degree glazed creosote packed into flues that haven’t been cleaned in five to ten years. Our wood-burning fireplace service includes Level-2 inspection, rotary sweeping, and documentation with photos. Wood-burning service in Hillsborough ranges from $220-$380 per flue.
Fireplace Insert
Adding an insert to a 1920s fireplace without damaging the masonry requires precise measurement and the right liner system. We use DuraFlex stainless steel liners sized to each flue’s exact dimensions, with proper top-sealing collars that prevent marine-layer moisture from entering the gap between liner and original clay tile. Fireplace insert installation in Hillsborough typically runs $2,800-$4,500 depending on unit size and liner length.
Damper Repair
Original decorative dampers on Hillsborough estates often fail to seal properly after decades of corrosion and heat cycling. We don’t install generic replacements. Our Fireplace Services team sources and fits dampers that match the estate’s original hardware proportions, including custom Copperfield units for non-standard throat dimensions. Damper repair or replacement in Hillsborough runs $340-$580.
Firebox Repair
Aged firebrick, cracked refractory panels, and deteriorated mortar joints are common in Hillsborough’s century-old hearths. We rebuild with HeatShield refractory materials rated for the thermal stress these large fireplaces generate. Firebox repair typically ranges $650-$1,200.
Fireplace Conversion
Converting from wood to gas, or gas to electric, on a historic masonry fireplace requires permit coordination and careful preservation of the original surround. We handle the technical work and document the change for disclosure when the home eventually sells. Conversion projects in Hillsborough start around $1,800 and range to $3,500 for complex multi-unit estates.
Trusted Brands We Service in Hillsborough
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. Our San Francisco warehouse stocks common liner diameters, damper sizes, and crown repair compounds, so Hillsborough customers aren’t waiting on freight for standard parts. When a 1920s estate needs something custom, we fabricate to spec rather than forcing a mismatched fit. The job is done right, and we stand behind it.
Common Fireplace Services Problems We See in Hillsborough Homes
- Single-flue cleaning misses hidden hazards. A technician who cleans one fireplace and leaves the other two or three untouched is doing half a job. We inspect and document every flue on the property, because Hillsborough estates demand batch service.
- Standard dampers destroy original proportions. Decorative dampers on Tudor Revival and Spanish Colonial fireplaces were sized to the opening’s architecture. A generic replacement looks wrong and often leaks. We match hardware to the original design.
- Marine fog accelerates mortar damage. Hillsborough’s persistent coastal moisture drives into aging crown joints and brick faces. Without proper sealing, spalling and efflorescence can destroy a chimney face within one winter season.
- Pre-sale inspections reveal decade-old neglect. Because Hillsborough fireplaces are largely ceremonial, many homeowners go years between cleanings. Then a sale or remodel triggers inspection, and we find multiple flues packed with glazed creosote and crumbling crowns. These jobs are among our most common calls in the 94010 ZIP.

FAQs - Fireplace Services in Hillsborough
Hillsborough legally bans all commercial and multi-family properties, so every structure is a large private estate built when multiple fireplaces signaled status and provided zone heating. Tudor Revival, Spanish Colonial, and Mediterranean estates from the 1920s through 1950s typically feature two to four original masonry fireplaces. If you’re buying or maintaining one of these homes, budget for batch service rather than single-flue pricing. Call (855) 408-5567 and we’ll scope every unit.
Moisture damage from marine-layer fog and winter rain accelerating spalling and efflorescence on aging mortar crowns and brick faces. The Peninsula’s coastal hills trap persistent moisture against chimney exteriors, and original clay tile liners with aged mortar joints offer little protection. We seal crowns with professional-grade compounds and install proper top-sealing dampers to break the wet-dry cycle. Annual inspection catches this before rebuild costs escalate.
Yes, and infrequent use can be more hazardous than regular burning. Low, smoldering decorative fires common in Hillsborough’s mild climate deposit proportionally heavy creosote per burn hour. Third-degree glazed creosote builds up in flues that sit idle for months, then ignite with explosive force when the fireplace is eventually used heavily. We recommend annual Level-2 inspection even for ceremonial fireplaces. The $89 Seasonal Tune-Up covers this.
Yes, with proper liner sizing and throat modification. We use DuraFlex stainless steel liners cut to each flue’s exact dimensions, with top-sealing collars that prevent moisture infiltration between liner and original clay tile. The original firebox and surround remain intact. Most conversions are completed in one visit. Call (855) 408-5567 for a free assessment of your specific fireplace.
Buyer inspections will examine every flue, and discoveries of glazed creosote or crumbling crowns can delay closing or trigger repair credits. We recommend pre-listing Level-2 inspections with photo documentation for all fireplaces. Addressing issues before listing puts you in control of timing and pricing. Our inspection reports are accepted by Peninsula real estate attorneys and transaction coordinators. Estimates are free.
