Fast, Reliable Fireplace Services Across Franklin Square
Fireplace repair and conversion in Franklin Square typically runs $280–$1,850 depending on whether we’re servicing an existing gas unit, rebuilding a firebox, or converting an old wood-burning system to a modern gas insert. Most Franklin Square appointments are scheduled within 24–48 hours, and Robert Garcia handles the diagnostic himself — not a subcontractor sent from a dispatch center.
We’ve been working in the 11010 ZIP and surrounding Nassau County blocks for 17 years, and Franklin Square’s postwar housing stock keeps our Fireplace Services team busy through every season. The Cape Cods and ranches between Hempstead Turnpike and the Southern State Parkway were built fast in the late 1940s and 1950s, with brick chimneys sized for coal and oil heat that now struggle to vent modern gas appliances properly. If your fireplace is smoking into the living room, your damper won’t seal, or you’re tired of hauling wood in a house that was never designed for it, we’ll diagnose the real problem and give you an upfront price before any work starts. Call (866) 884-9512 for a free estimate.

Why Apex Chimney Cleaning Greater New York Is Franklin Square’s Preferred Fireplace Services Company
Our reputation in Franklin Square is built on showing up personally. Robert Garcia is the owner and the lead technician on every fireplace job — when you book with Apex, you’re not getting a rotating crew that needs to call a manager for approval. You’re getting the decision-maker on your property, someone who can spot a mismatched flue liner from the basement up and authorize the fix on the spot.
That accountability shows in the numbers: 1,096 verified customer reviews averaging 4.7 stars, with a significant share coming from repeat Franklin Square homeowners who’ve had us back for chimney sweeps, cap replacements, and full fireplace conversions. We’re familiar with the specific failure patterns in Cambria Heights ranches and Mott Section Capes — the chronic downdrafts, the condensation staining, the cracked clay tiles that every local inspector has learned to expect.
Response time to Franklin Square is typically same-day or next-day for standard calls, and we keep common parts and liner materials stocked for the brands we service most. No waiting two weeks for a specialty fitting while your fireplace sits unusable through a cold snap.
Our Fireplace Services in Franklin Square
Gas Fireplace Service
Gas fireplace service in Franklin Square runs $180–$340 for a standard cleaning, inspection, and burner adjustment. Many of the gas fireplaces we service here were converted from wood-burning originals during the 1990s and 2000s, often with the original oversized flue left in place. That mismatch creates soot buildup on glass doors, delayed ignition from poor oxygen mix, and pilot lights that blow out in wind coming off the Atlantic. We clean the burner orifices, check gas pressure at the manifold, and inspect the venting configuration against the appliance rating plate — because a 1950s chimney venting a 2010s insert is a recipe for condensation damage we see weekly in Franklin Square.
Wood Burning Fireplace
Wood-burning fireplace repair and rebuilding in Franklin Square typically costs $850–$2,400 for firebox refractory panel replacement or damper restoration, scaling to $4,500–$8,500 for full firebox rebuilds in severely deteriorated chimneys. The freeze-thaw cycles here — more frequent than upstate New York because Franklin Square’s winters hover right around 32°F rather than staying deeply cold — destroy the mortar between firebox bricks and spall the rear wall where heat concentrates. We inspect for creosote glazing, cracked throat dampers, and smoke chamber deterioration, then recommend repair or conversion based on what we find. In many Franklin Square homes, converting to gas is the smarter long-term play.
Fireplace Insert Installation
Fireplace insert installation in Franklin Square ranges from $2,800–$4,500 for a direct-vent gas insert with basic surround, or $3,800–$6,200 for a high-efficiency model with blower, remote, and custom trim kit. The critical step every time: verifying that the existing flue is properly sized and lined for the insert’s BTU output. We regularly pull out failed insert installations done by general contractors who never checked the chimney — the insert ran fine for two seasons, then the homeowner noticed water staining on the ceiling above the firebox. That’s almost always an unlined or oversized flue condensing moisture back into the structure. We use DuraFlex stainless steel liners and HeatShield resurfacing where appropriate, sized precisely to the appliance.
Damper Repair & Replacement
Damper repair in Franklin Square costs $220–$480 for throat damper adjustment, hinge welding, or seal replacement; full damper replacement runs $650–$1,200 including a top-sealing energy-efficient model. The dampers we replace most often in Franklin Square are original cast-iron units from the 1950s and 1960s, corroded by decades of acidic condensation from oil and gas exhaust. In the Mott Section especially, we’ve found dampers frozen solid with rust flakes — the homeowner didn’t even know it was supposed to move. A stuck-open damper bleeds heated air up the chimney all winter; a stuck-closed one traps smoke and carbon monoxide in the living space. We test operation, measure throat dimensions, and install the correct replacement on the same visit when possible.
Fireplace Conversion
Fireplace conversion — wood-to-gas or oil-to-gas — is our most called-for service in Franklin Square, running $3,200–$6,800 depending on whether we need to reline the chimney, rebuild the firebox front, or run new gas supply from the basement. This is where Franklin Square’s housing history creates problems that generic fireplace companies miss. The original 8×8 or 8×12 clay flue liners in these postwar homes were engineered for 400–600°F oil exhaust temperatures. Modern gas appliances run 250–350°F. Oversized flues chill the exhaust before it reaches the top, creating acidic condensation that eats mortar, stains brick, and destroys metal components.
We serviced a 1950s ranch on a quiet block in the Mott Section where the homeowner had converted to gas five years ago. The original 8×8 clay liner was so oversized that exhaust gases chilled too quickly, creating heavy condensation that dripped onto the firebox floor and corroded the damper assembly. We installed a 6-inch DuraFlex stainless steel liner to match the gas appliance, solving the chronic downdraft and moisture damage in one afternoon.
Firebox Repair
Firebox repair in Franklin Square ranges from $450–$1,200 for refractory panel replacement or tuckpointing of deteriorated mortar joints, to $2,800–$5,500 for partial rebuilds where the rear wall has buckled or side walls have pulled away from the chimney structure. The fireboxes in Franklin Square’s 60–80 year old chimneys were built with common brick and lime mortar, not the refractory materials used in modern construction. After decades of thermal cycling and moisture intrusion from failed crowns, the mortar turns to sand and the bricks loosen. We rebuild with proper firebrick and high-temperature refractory mortar, restoring safe containment of combustion gases.
Trusted Brands We Service in Franklin Square
We install and service professional-grade fireplace products from DuraFlex, HeatShield, and Gelco — the same lines specified by commercial chimney contractors, not the budget hardware-store brands that fail in three seasons. For Franklin Square homeowners, this means we can often source replacement parts and liner components without the two-week wait times that plague specialty orders. Robert Garcia keeps common DuraFlex liner diameters and Gelco cap sizes in rotation for the Cape Cod and ranch configurations that dominate the 11010 ZIP. When your fireplace needs a part, we don’t guess at compatibility — we match the manufacturer’s specification to your chimney’s actual dimensions.
Common Fireplace Services Problems We See in Franklin Square Homes
- Original clay liners from the 1940s–60s develop hairline cracks from freeze-thaw cycles. Franklin Square’s position on Long Island’s south shore means more freeze-thaw events per winter than upstate regions, and each cycle opens cracks wider in aging clay tile. Once cracked, these liners allow carbon monoxide and combustion gases to seep into wall cavities and living spaces — especially dangerous after gas conversions, which produce odorless CO that won’t alert occupants until levels are hazardous.
- Oversized flues left from oil-to-gas retrofits cause condensation staining and accelerated brick spalling. This is the signature Franklin Square problem. The large-diameter clay liner sized for oil combustion chills modern gas exhaust before it exits, producing acidic moisture that stains the firebox brown, corrodes metal components, and rots mortar from the inside out. We see this pattern on most fuel-switch homes in the Mott Section and surrounding blocks.
- Deteriorated crowns and chimney caps on 60–80 year old structures allow water intrusion. Franklin Square’s wet Atlantic climate — heavy spring rains, humid summers, and wind-driven precipitation off the ocean — saturates chimney tops where the crown has cracked or the cap is missing. Water enters, freezes in winter, and produces frost heave that can literally push a chimney off plumb. We’ve rebuilt crowns on homes near John Paul Jones Park where the lean was visible from the street.
- Failed or missing dampers waste energy and create safety hazards. Original throat dampers in Franklin Square’s postwar housing were never designed for decades of continuous use, and many are now rusted open, rusted shut, or missing entirely. An open damper in winter is an 8-inch hole dumping heated air; a closed damper with a lit fire is a smoke and CO emergency waiting to happen.

FAQs — Fireplace Services in Franklin Square
Yes, almost certainly. The original 8×8 or larger clay liners in Franklin Square’s postwar homes were engineered for 400–600°F oil exhaust, while gas appliances run 100–250°F cooler. That temperature mismatch causes acidic condensation that destroys mortar and metal components from the inside. We replace these with properly sized stainless steel liners — typically 5″ or 6″ diameter for residential gas — which vent efficiently and stop the moisture damage. Call (866) 884-9512 and we’ll scope the flue to confirm condition; estimates are free.
Franklin Square experiences more freeze-thaw cycles per winter than upstate New York because temperatures hover near 32°F rather than staying consistently below freezing. Each cycle forces water in mortar joints to expand and contract, progressively cracking clay tiles and spalling brick faces. We’ve removed liner sections in Cambria Heights homes where a single winter produced new cracks visible to the naked eye. Annual inspection catches this before gases migrate into living spaces.
The brown staining is acidic condensation from an oversized flue chilling gas exhaust before it exits. This is the signature problem in Mott Section and surrounding Franklin Square blocks where oil-to-gas conversions retained original clay liners. The moisture carries sulfur compounds that stain masonry brown and corrode metal dampers. We solve it by installing a properly sized stainless steel liner — usually DuraFlex — that maintains exhaust temperature to the chimney top, eliminating condensation at its source. Call (866) 884-9512 for a free inspection.
Sometimes, but not usually in Franklin Square’s 1940s–1960s housing. The original flue is almost always oversized for modern gas inserts, and most lack a proper liner entirely. A direct-vent gas insert with its own coaxial venting can bypass the chimney in some configurations, but we still need to verify clearances, combustible exposure, and structural integrity. We give honest assessments — if a conversion needs a reline, we say so upfront with an exact price. No surprises after demolition starts.
We install and service inserts from major manufacturers and supply liner systems from DuraFlex, HeatShield, and Gelco to ensure proper venting integration. For Franklin Square’s common chimney configurations — narrow flues in Cape Cods, offset chimneys in ranches — we match the insert’s venting requirements to the actual masonry dimensions, not guess based on the sales brochure. If you already have an insert needing service, bring the model plate information and we’ll confirm parts availability before scheduling.
