Fast, Reliable Fireplace Services Across Cambridge
Our Chimney Repair in Cambridge and fireplace service typically runs $180-$650 depending on the repair, and our technicians can reach most Cambridge neighborhoods within 45 minutes. We’re familiar with the triple-decker chimneys of East Cambridge and the ornate Victorian hearths along Brattle Street, so we don’t waste time figuring out what we’re looking at. Call (844) 803-1545 and a live person will answer, 24 hours a day.
Cambridge’s housing stock tells a story that matters for your fireplace. Those late-Victorian and Edwardian multi-family buildings, the wood-frame triple-deckers in 02141 and the grand single-family homes near Avon Hill, were built for coal and converted through oil to gas across successive decades. Each fuel change left its mark on your flue, your damper, your firebox. We’ve worked on these exact buildings for over 42 years. We know what the previous conversions did to your system, and we know how to fix it without starting over.
Our Fireplace Services team carries the parts and tools to complete most jobs in a single visit. That’s not a convenience promise; it’s a practical necessity when you’re dealing with a heating system in a Cambridge January.

Why Hearthstone Chimney Co. Is Cambridge’s Preferred Fireplace Services Company
We’ve been serving Cambridge since 1984, long enough to have worked on the same chimney twice as ownership changed hands. Russell Haines built this company on the principle that a craftsman who plans to be in town in thirty more years acts accordingly. No shortcuts, no disappearing acts.
Our reputation here is specific. Cambridge homeowners call us back because we document every inspection with photos they can see and a plain-English verdict they can understand. No engineering jargon, no vague warnings. You see what we see, and you know exactly what needs doing.
Response time to Cambridge averages under 45 minutes from dispatch. We’re not routing calls through a national queue; a live person answers the phone 24/7, schedules the technician, and confirms the arrival window. We’ll be there when we say.
Our local knowledge runs deeper than geography. We understand the rental-market dynamics that drive deferred maintenance in Cambridge’s university-heavy housing stock, and we know how to communicate with both owner-occupants and landlords navigating certificate-of-occupancy inspections. That matters when your four-flue chimney stack serves three separate units and everyone’s safety depends on proper separation.
Our Fireplace Services in Cambridge
Gas Fireplace Service
For our Chimney Cleaning & Sweep in Cambridge and gas fireplace service, standard maintenance typically costs $180-$320 and $340-$650 if the gas valve, pilot assembly, or thermopile needs replacement. Most Cambridge conversions from oil to gas happened in the 1970s and 1980s, and the original gas logs or inserts are now well past their designed service life. We see a lot of rusted burner pans in the damp basements of North Cambridge triple-deckers, where the previous conversion left the firebox exposed to moisture from below. Our technicians carry DuraFlex and HeatShield materials to reseal the firebox and restore proper draft in the same visit.
Wood Burning Fireplace
Wood-burning fireplace repair in Cambridge runs $220-$480 for firebox patching or damper work, and $450-$1,200 if the smoke chamber needs parging or the flue requires relining. The Victorian homes along Brattle Street and in Avon Hill often have multiple original fireplaces with elaborate decorative flues that were never designed for modern heating loads. Original terracotta liner tiles, cracked from repeated fuel-type transitions and thermal cycling, are the near-universal finding on our Level-2 camera inspections. We document the damage with photos, explain the verdict in plain English, and repair with professional-grade materials from Famco and Copperfield.
Fireplace Insert
Fireplace insert installation or repair in Cambridge typically ranges $1,800-$3,400 for a properly sized and vented unit, including the liner connection to the existing flue. In Cambridge’s triple-decker market, we’ve seen too many inserts added without permits, vented into flues sized for a different appliance, creating carbon monoxide risks that Cambridge’s rental-inspection enforcement increasingly flags. We size the insert to the flue, install the correct stainless steel liner from DuraFlex, and provide documentation that satisfies both the building inspector and your insurance carrier.
Damper Repair
Damper repair in Cambridge usually costs $180-$340 for a top-sealing damper replacement or $220-$420 if the throat damper mechanism has corroded beyond repair. Cambridge’s damp winters, with the city flanked by the Charles River and close to Boston Harbor, mean throat dampers rust faster here than in drier inland climates. A stuck or missing damper costs you heated air every minute your fireplace isn’t in use. We stock top-sealing dampers from Gelco and Olympia Chimney that seal tighter and operate more reliably than the original cast-iron throat dampers in most Cambridge homes.
We also handle Chimney Cap & Crown in Cambridge and Chimney Liner & Rebuild in Cambridge when the problem runs deeper than the fireplace itself.
Trusted Brands We Service in Cambridge
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes, no corner-cutting on parts that live inside your chimney where you can’t see them. We stock common damper assemblies, gas valves, and firebox refractory panels locally, so most Cambridge repairs don’t wait on shipping. When your heat is out in February, that matters. The brands we use are the same ones specified by factory-built fireplace manufacturers and recommended by the Chimney Safety Institute of America. Done right, and we stand behind it.
Common Fireplace Services Problems We See in Cambridge Homes
- Freeze-thaw crown deterioration on pre-1940 stacks. Cambridge’s cold, damp winters and proximity to the Charles River mean exposed chimney crowns absorb moisture that expands and contracts through repeated freeze-thaw cycles. Lime-mortar joints on Victorian and Edwardian stacks deteriorate quickly under this load, making annual crown and flashing inspections before October particularly urgent.
- Liner-sizing mismatches from successive fuel conversions. The typical Cambridge triple-decker chimney has been converted from coal to oil to gas over decades, with each changeover often leaving the original liner in place. A flue sized for coal is too large for modern gas appliances, causing condensation, corrosion, and draft problems that show up as soot staining or moisture damage on interior walls.
- Cross-flue contamination in multi-unit chimney stacks. In East Cambridge’s four-flue triple-decker chimneys, it’s common to find one flue serving an active gas furnace, another serving a tenant’s wood-burning insert added without a permit, and one or two capped but not properly sealed. Carbon monoxide and smoke pathways can cross between units, a code and liability scenario that Cambridge’s dense rental-inspection enforcement increasingly flags.
- Abandoned flues open to active ones. When a previous owner converted from oil to gas and abandoned the old flue, they often capped it at the top but left it open at the bottom in the basement or chase. That open connection draws conditioned air out of your home year-round and can become a pathway for combustion gases if the separation between flues has deteriorated.
