Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Fireplace services in Bordentown typically run $180-$650 depending on whether you need a routine tune-up, damper repair, or full firebox restoration, and most appointments are completed in a single visit. Our Fireplace Services team understands the specific risks of Bordentown’s pre-Civil War housing stock - shared chimney stacks, unlined flues, and soft colonial brick that behaves differently than modern masonry. If you smell exhaust when your neighbor’s furnace runs, or you’ve noticed crumbling mortar around your firebox, call (856) 519-0832. A live person answers, 24 hours a day.
We’ve been working in Burlington County for over 42 years, and Bordentown’s historic district presents challenges you won’t find in Chesterfield’s split-levels or Florence’s ranch developments. The dense rowhouses along Farnsworth Avenue, the Federal-era homes near the river bluff, and the Victorian properties off Crosswicks Street each carry distinct fireplace and chimney characteristics that demand more than a generic sweep.

Why Hearthstone Chimney Co. Is Bordentown’s Preferred Fireplace Services Company
Bordentown homeowners know the difference between a technician who reads a checklist and one who reads a chimney. Our reputation here was built on the latter.

Response time to Bordentown addresses is typically within a few business days for standard appointments, though our 24/7 live answering means you can always reach us to discuss urgency. We know the tight street parking around the historic district, the limited roof access on attached rowhouses, and the specific permitting considerations when working on contributing structures in a nationally recognized historic district. That local fluency saves time and prevents mistakes.

Our Fireplace Services in Bordentown
Gas Fireplace Service
Gas fireplaces in Bordentown’s historic homes often sit in original wood-burning fireboxes with flues that were never properly lined for gas combustion. The pattern is familiar: a colonial-era home on Park Street or a Greek Revival on Farnsworth gets converted to gas heat in the 1960s or 70s, and the installer simply vents into the existing unlined rubble-stone flue. Our gas fireplace service includes combustion analysis, burner inspection, and a camera evaluation of the flue condition. If we find an unlined flue venting a gas appliance, we’ll show you the footage and explain your options. A proper stainless liner or a listed venting system is not optional - it’s the barrier between combustion gases and your living space.

Wood Burning Fireplace
There’s nothing wrong with burning wood in a Bordentown fireplace, provided the system was built for it and maintained accordingly. The problem we encounter is original fireplaces that haven’t been evaluated since the Carter administration. Soft colonial-era brick, lime mortar that has been patched repeatedly, and smoke chambers narrowed by decades of creosote buildup all reduce draft and increase fire risk. Our wood burning fireplace service includes a Level-2 camera inspection of the full flue, firebox, and smoke chamber, plus a written condition report. In Bordentown’s river-corridor climate, moisture accelerates deterioration of antique masonry, so we pay particular attention to spalled brick and deteriorated mortar joints that could allow heat transfer to adjacent framing.

Fireplace Insert Installation & Service
A fireplace insert can transform a drafty, inefficient open fireplace into a useful heat source, but installation in Bordentown’s historic chimneys requires careful evaluation. The insert must be paired with a properly sized liner - typically a flexible stainless system from DuraFlex or a comparable professional-grade brand - run the full height of the flue. We do not install inserts into unlined flues, period. The confined space and shared-stack configurations common along Farnsworth Avenue and the surrounding historic grid make proper liner installation technically demanding. Our technicians have the equipment and experience to navigate these tight spaces and ensure the liner is correctly supported and sealed at every joint.

Damper Repair & Replacement
A failed damper is more than an inconvenience. In Bordentown’s windy river-corridor location, a damper that won’t fully close costs you significant conditioned air up the flue year-round. A damper that won’t fully open risks smoke spillage into the room. We repair and replace throat dampers, top-sealing dampers, and the specialized cast-iron assemblies found in original Bordentown fireplaces. Top-sealing dampers from brands like Gelco or Famco often make sense in these homes, as they seal at the chimney top rather than the smoke chamber, providing better protection against moisture and wind-driven downdrafts. We’ll show you the condition of your existing damper on camera and explain whether repair or replacement is the square deal.

Fireplace Conversion
Converting a wood-burning fireplace to gas is one of our most requested services in Bordentown, and for good reason. Gas is cleaner, more convenient, and better suited to many homeowners’ lifestyles. But conversion in a historic chimney is not a matter of running a gas line and lighting a burner. The flue must be evaluated for compatibility with gas combustion products, which are cooler and more moisture-laden than wood smoke. An unlined or deteriorated flue will not safely vent gas appliances. We perform a full Level-2 inspection before quoting any conversion, and we will not proceed without a proper liner system installed. The number on our estimate is the number on the invoice - no surprises after we’ve opened the wall.

Firebox Repair
The firebox is where the fire actually lives, and in Bordentown’s oldest homes, it’s often in rough shape. Decades of thermal cycling crack refractory panels, loosen firebrick, and erode mortar joints. Worse, the original construction may have used common brick rather than proper firebrick, a shortcut that accelerates deterioration. We repair fireboxes with HeatShield refractory restoration systems or with traditional firebrick and high-temperature refractory mortar, depending on the application and the homeowner’s goals. Every firebox repair is documented with before-and-after photos, and all work is covered by our 90-Day Done Right Promise.

Trusted Brands We Service in Bordentown
We work exclusively with professional-grade materials from industry-trusted manufacturers. For liner systems, we specify DuraFlex flexible stainless steel and HeatShield refractory restoration products. For caps, dampers, and ventilation components, we source from Famco, Gelco, and Copperfield. These are not builder-grade substitutes - they’re the materials we trust in our own homes, and we stock common sizes to keep turnaround short for Bordentown customers. When your shared-stack rowhouse needs a liner installed before the next heating season, waiting six weeks for parts is not acceptable. We plan our inventory to avoid that scenario.
Common Fireplace Services Problems We See in Bordentown Homes
- Cross-contamination in shared stacks. Because the pre-Civil War rowhouses along Farnsworth Avenue frequently share a single multi-flue stack between adjacent properties, a wood-burning fireplace in one home can backdraft into a neighbor’s gas appliance flue when the shared stack lacks a proper liner and separation. This cross-contamination risk is specific to Bordentown’s dense historic grid and rarely occurs in the detached, newer housing of surrounding townships.
- Adjacent flue reversal from negative pressure. Adjacent flues in shared stacks pull combustion gases from a neighbor’s gas appliance into the fireplace firebox when negative pressure from tight historic windows reverses the draft. We test for this condition during every Level-2 inspection in attached properties.
- Freeze-thaw spalling on river-exposed masonry. Bordentown sits on a bluff directly above the Delaware River, meaning chimneys are exposed to elevated ambient moisture from the river corridor year-round and to persistent northwest winds that accelerate freeze-thaw spalling on the exposed upper courses of masonry stacks. Winter freeze-thaw cycling in Burlington County is severe enough that soft antique brick - already more porous than modern brick - tends to face-spall noticeably faster here than in inland towns just miles away.
- Unlined flues venting gas appliances. A pattern local sweeps know well: colonial-era homes in the historic district were often converted from wood-burning to oil or gas heat decades ago, but the original unlined rubble-stone or soft-brick flues were simply left in place and are now venting combustion appliances without any liner - a serious CO risk that comes up repeatedly on inspection calls in this zip code.

FAQs - Fireplace Services in Bordentown
Yes, and this is one of the most serious hazards we find in Bordentown’s historic district. When adjacent flues in a shared stack are unlined or improperly separated, combustion gases from a gas appliance can migrate into a neighboring flue under certain pressure conditions. We were called to a Greek Revival rowhouse on Farnsworth Avenue where the homeowner reported a faint exhaust smell whenever the neighbor’s gas furnace cycled on. Our tech performed a Level 2 inspection with a camera and found the shared stack had two unlined flues side-by-side, with the gas appliance venting directly into the same rubble-stone cavity as the wood fireplace. We installed a HeatShield liner in the wood flue and a separate stainless liner for the gas side, restoring proper draft and eliminating the cross-contamination. If you share a stack, a Level-2 inspection is essential. Call (856) 519-0832 to schedule - estimates are free.

Bordentown’s river-bluff location exposes chimneys to more moisture and more severe freeze-thaw cycling than inland towns. The Delaware River corridor generates persistent ambient humidity, and northwest winds drive rain and snow into masonry joints. Soft colonial-era brick, already more porous than modern materials, absorbs this moisture and spalls during winter freeze-thaw cycles. We’ve seen face-spalling on 20-year-old repointing jobs in Bordentown that still looks perfect in Chesterfield, just ten miles inland. The combination of antique materials and aggressive local weather means Bordentown chimneys need more frequent evaluation and more careful repair specification. Call (856) 519-0832 and we’ll show you exactly what your masonry is doing.

No, and any contractor who suggests otherwise is cutting a corner that could cost you your home. Gas combustion produces water vapor and corrosive compounds that condense in cool, unlined flues. An original Bordentown rubble-stone or soft-brick flue was designed for hot wood smoke, not cool gas exhaust. Without a proper stainless liner, that condensate soaks into mortar joints, accelerates deterioration, and can allow carbon monoxide to seep through into living spaces. Our conversion process always includes a Level-2 inspection, liner sizing, and installation of a listed liner system before the gas appliance is connected. The upfront cost is higher. The alternative is not safe. Call (856) 519-0832 for a conversion estimate that includes everything required to do it right.

A Level-2 inspection is a camera-assisted evaluation of the full interior flue, smoke chamber, firebox, and accessible exterior masonry. We use a high-resolution camera on a flexible rod to document every surface, and we provide you with the photos and a written verdict. In a historic Bordentown home, this is essential because original construction may include unlined flues, shared stacks, or multiple generations of incompatible repairs that aren’t visible from the firebox opening. You cannot evaluate these conditions with a flashlight and a mirror. The inspection typically takes 60-90 minutes and is included free with any service estimate. Call (856) 519-0832 to schedule.

The National Fire Protection Association recommends annual inspection for all chimney systems, and in Bordentown’s climate and housing stock, we agree. The combination of river-corridor moisture, severe freeze-thaw cycling, and antique masonry means conditions can change faster than in newer, inland construction. If you burn wood regularly, an annual sweep and inspection is the minimum. If you have a gas appliance venting through an original flue, annual inspection is non-negotiable - CO leaks develop without visible warning. We offer an $89 Seasonal Tune-Up for gas fireplaces and full sweep packages for wood-burning systems. Call (856) 519-0832 to book at a time that works for you.
