Our Chimney Liner & Rebuild Services in Marlton
Stainless Steel Liner Installation
A stainless steel liner is the permanent fix for most Marlton prefab systems that have outlived their original metal flue components. We install DuraFlex stainless steel liners rated for the temperature cycles of both gas and solid-fuel appliances. In Marlton’s 1960s-1990s subdivisions like Kings Grant, the predominant prefab fireplaces from Heatilator and Majestic are now hitting a 30-40 year design life, making liner and rebuild work a routine necessity rather than an exception. A stainless steel liner eliminates the rust-through failures we see on original galvanized adapters and gives you a venting path that meets current NFPA 211 standards.
Flexible Liner Systems
Not every Marlton chimney chase is straight. Flexible liners from DuraFlex navigate offset flues and tight clearances in split-level homes where rigid pipe won’t fit. We size the liner to your appliance’s BTU output, not guess. Flexible systems work particularly well in Marlton’s ranches and colonials where the original builder squeezed a prefab unit into a narrow chase with minimal clearance to combustibles.
Liner Replacement
When the original factory liner has failed, partial replacement won’t do. We remove the damaged section, inspect the surrounding chase enclosure for water damage, and install a complete replacement liner sized to the appliance. On a recent call in the Kings Grant neighborhood, we found a Majestic prefab unit where the original round-to-oval flue adapter had rusted through, funneling rainwater into the chase for months. Our crew replaced the entire flue assembly with a DuraFlex stainless steel liner and sealed the chase cover to stop further damage. Liner replacement in Marlton typically runs $2,200-$3,800 for a standard prefab system.
Partial Rebuild
Sometimes the liner is sound but the chase enclosure, firebox surround, or refractory panels have failed. Partial rebuilds address the damaged components without replacing the entire system. In older Marlton planned communities, prefab chase enclosures built with OSB or thin vinyl siding were never designed to last 40 years. Local techs regularly find that a routine cleaning call turns into a water-damage discovery once a rusted-through chase cover has been silently funneling rain into the framing around the firebox for a full season. We rebuild with proper weatherproofing, fire-rated materials, and a chase cover that sheds water instead of collecting it. Partial rebuilds in Marlton range from $1,800-$4,500 depending on how far the water traveled before you called.

Trusted Brands We Service in Marlton
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Marlton’s aging prefab inventory, we stock DuraFlex stainless liners and Famco chase covers because they’re the components we install most often in ZIP 08053. Having parts on the truck means most Marlton jobs finish in one visit, not two. The brands we use are the same ones specified by Heatilator and Majestic for factory-authorized repairs, so your system maintains its intended safety clearances and venting performance.
Common Chimney Liner & Rebuild Problems We See in Marlton Homes
- Rusted chase covers funneling water into firebox framing. The galvanized sheet-metal chase covers original to most Marlton prefab units weren’t built for 40 years of mid-Atlantic freeze-thaw. Once they rust through, water follows the flue pipe straight into the chase enclosure and surrounding wall framing.
- Cracked or deteriorated refractory panels on Heatilator and Majestic zero-clearance fireplaces. These panels reflect heat back into the firebox and protect surrounding combustibles. After decades of thermal cycling, they crack or crumble. We replace with factory-spec panels or upgrade to a stainless liner system if the damage is extensive.
- Original prefab flue adapters failing after decades of freeze-thaw cycles. The round-to-oval adapters that connect factory-built fireboxes to vertical flue pipes are a known failure point in Marlton’s housing stock. Marlton’s mid-Atlantic winters deliver repeated freeze-thaw cycles that are punishing to the galvanized sheet-metal chase covers and prefab flue components common throughout the area’s aging subdivisions.
- Interior rust in metal-liner systems from extended idle periods. Proximity to the Pine Barrens’ damp, sandy terrain keeps ambient humidity elevated through shoulder seasons, accelerating interior rust in metal-liner systems that sit idle from April through October. Marlton homeowners who use their fireplaces only December through February often discover liner failure on the first cold snap of the season.

FAQs - Chimney Liner & Rebuild in Marlton
Prefab fireplaces have a 30-40 year design lifespan, and most of Marlton’s inventory was installed between the late 1960s and early 1990s. Masonry chimneys can be repointed and rebuilt indefinitely; prefab units have metal components that simply wear out. If your Heatilator or Majestic unit is original to the house, the flue adapter and chase cover are likely past their service life. Call (866) 580-4069 for a free inspection and written estimate.
Rusted chase covers are the single most common failure we find in Marlton’s 1960s-1990s subdivisions. The original galvanized covers corrode, water enters the chase, and the damage spreads to the flue adapter, firebox framing, and surrounding wall structure. Caught early, it’s a chase cover and liner replacement. Left alone, it becomes a partial rebuild. We document everything with photos so you can see exactly what we’re describing.
Small hairline cracks can sometimes be addressed with factory-approved refractory cement, but panels with gaps, spalling, or structural cracks must be replaced. We don’t patch panels that have lost their insulating properties, because that’s a safety issue, not a cosmetic one. If multiple panels are damaged or the firebox surround shows water intrusion, we recommend a partial rebuild with new panels and a liner inspection. We’ll show you the photos and give you both options with prices.
DuraFlex stainless steel liners are our first choice for Marlton’s prefab systems because they’re listed for both the temperature ratings and the venting configurations common in Heatilator and Majestic units. We also use HeatShield cerfractory sealant for certain factory-authorized resurfacing applications. Both brands maintain the safety clearances your zero-clearance system was designed for, which generic hardware-store liner kits do not. We stock both on our Marlton service trucks.
Indirectly, yes. Marlton’s proximity to the Pine Barrens means higher ambient humidity through spring and fall, which accelerates interior corrosion in metal liners that aren’t being used and vented regularly. A stainless steel liner resists this better than the original galvanized components, and proper chase cover sealing keeps the humid outside air from condensing inside the flue. If your fireplace sits idle six months a year, we recommend an annual inspection to catch rust before it perforates the liner wall.
