Fast, Reliable Gas Fireplace Repair Across Franklin Square
Gas fireplace repair in Franklin Square usually costs between $165 and $520 depending on what’s actually wrong, and most service calls can be scheduled within a few days, not weeks. We’ve been fixing gas fireplaces across Franklin Square since 2002, and the homes here present a very specific set of problems most repair companies aren’t looking for. If your gas fireplace is drafting poorly, smelling musty, or making odd noises, call (518) 719-4643 and we’ll walk you through what we’re likely to find before we even arrive.
Franklin Square’s housing stock is dense with 1950s and 60s split-levels, capes, and ranches, and a surprising number still carry the original dual-flue chimney built for an oil furnace and a wood fireplace. Many of those homes have since converted to gas but kept the abandoned flue uncapped, which sets up a repair scenario you won’t find in newer towns. We know what to look for because we see it every week on blocks from Rath Park down to the Hempstead Turnpike corridor.

Our Gas Fireplace Repair Services in Franklin Square
We start every gas fireplace repair in Franklin Square with a real inspection. Not a quick visual check, but a camera look at the flue liner, the firebox, the damper, and any abandoned second flue. That’s the difference between fixing what’s in front of you and fixing what’s actually causing the problem.
Chimney Cap Installation and Sealing
Franklin Square’s older homes frequently have uncapped or damaged chimney caps, especially on the abandoned oil flue that was never dealt with after a gas conversion. Rain gets in, squirrels get in, and rust spreads into the gas firebox below. We install proper stainless steel caps with side screens that keep moisture and animals out while still allowing the gas flue to vent. A sealed cap on both flues prevents the exact cascade of damage we see most often in this area.
Damper Replacement and Repair
Salt-laden coastal air from the Atlantic accelerates corrosion on gas fireplace dampers. In Franklin Square, a damper that’s rusted open lets warm air escape in winter and pulls musty outdoor air into the house in summer. We replace rusted dampers with top-sealing models built for gas systems, and we show you the removed part so you can see exactly why it failed.
Flue Liner Inspection and Cleaning
Gas fireplaces still produce creosote, especially when homeowners burn artificial logs or vented gas logs without regular service. A gas flue liner packed with buildup restricts draft and pushes carbon monoxide back into the living space. We camera the entire liner, show you the footage, and clean it with rotary brushes sized for gas flue pipe. If the liner is cracked or deteriorating, we tell you plainly whether it can be resurfaced with HeatShield or needs replacement with a DuraFlex system.
Firebox Repair and Gas Log Service
The firebox is where rust and moisture show up first, particularly in Franklin Square homes where an abandoned flue has been leaking into the system. We repair firebox panels, replace failed gas logs, adjust burners, and troubleshoot ignition, thermocouple, and pilot issues. Every repair is documented with photos, and you get a written guarantee covering the work for a full year. If it fails, the second visit is free.

AfterCommon Gas Fireplace Repair Problems We See in Franklin Square Homes
- Uncapped abandoned oil flues. Franklin Square’s dual-flue mid-century chimneys frequently leave the old oil flue open after conversion to gas. Rain and squirrels enter, rust forms, and the gas firebox suffers. We seal these flues with proper caps and screens as part of the repair.
- Rusted dampers from salt air. Coastal air carries salt that accelerates rust on damper assemblies. A damper that won’t open or close properly compromises both efficiency and safety, and it’s one of the most common replacements we make in Franklin Square.
- Cracked chimney crowns from freeze-thaw cycles. Wet, snowy winters followed by cold snaps crack the crown above the flue. Water drips down into the firebox, damages gas logs, and feeds rust. A crown repair or rebuild stops the water at the source.
- Creosote buildup in gas flues. Gas fireplaces are not maintenance-free. Burned logs and vented gas sets create first-degree creosote that narrows the flue and reduces draft. We clean gas liners as part of a standard service, not as an add-on surprise.

FAQs – Gas Fireplace Repair in Franklin Square
A musty odor from a gas fireplace that’s not in use almost always points to moisture intrusion, and in Franklin Square the usual culprit is an uncapped abandoned flue on a dual-flue chimney. When the old oil flue was never sealed after conversion to gas, rainwater and humidity enter the chimney, soak into soot and creosote, and push that damp smell into the living space. The fix is sealing the abandoned flue with a proper cap, and we’ll camera both flues to confirm no other entry points exist. Call (518) 719-4643 to schedule a moisture inspection.
Yes, gas fireplaces need an annual inspection in Franklin Square because the flue still accumulates creosote, the damper still rusts from salt air, and the crown still cracks from freeze-thaw cycles. Gas logs burn cooler and often vent less efficiently than wood, which means soot and moisture linger longer inside the liner and accelerate deterioration. An annual camera inspection catches rusted dampers, cracked liners, and moisture damage before they become a repair or a safety issue. Most Franklin Square homeowners book this in early fall before heating season starts.
Yes, and the cost is usually between $140 and $210 as a standalone service. Gas fireplaces, particularly those burning vented gas logs or artificial logs, produce first-degree creosote that sticks to the flue liner and reduces draft. We use rotary brushes sized specifically for gas flue pipe and follow up with a camera inspection to show you the inside of the liner after cleaning. If the liner shows damage, we’ll tell you plainly whether HeatShield resurfacing or a DuraFlex replacement is needed, with a written price before any work proceeds.
A rusted damper in Franklin Square is usually caused by salt-laden coastal air combining with moisture from an uncapped flue or a leaking crown. The salt accelerates corrosion, and the damper eventually seizes or breaks. A rusted damper can rarely be repaired effectively; replacement is the honest fix. We install top-sealing or throat dampers built for gas systems, priced from $220 to $410 installed, and we show you the removed part so you can see exactly what failed. The replacement carries our 365-day written guarantee.
Franklin Square homes built in the 1950s and 60s were commonly designed with two flues: one for the oil furnace and one for the living room fireplace. When the home converted to gas, the oil flue was often left uncapped and abandoned. That open flue lets rain and squirrels into the chimney system, causing rust and draft failure in the gas fireplace flue next to it. It matters because a proper gas fireplace repair here means inspecting and sealing both flues, not just the one connected to the gas firebox. A generic repair that ignores the second flue misses the actual source of the problem, and the issue returns within months.
