We’ve been driving to Fort Washington since 1984. We know the difference between a 1910 fieldstone chimney with corbeled flue throats and a 1950s Philadelphia brick colonial with combined flue systems. That knowledge matters when we’re sizing liners for a multi-flue stack or deciding whether your crown needs patching or your chimney needs a partial rebuild from the roofline up. Our Chimney Liner & Rebuild team carries DuraFlex and HeatShield materials on every truck, so we’re not ordering parts while your fireplace sits cold.

Our Chimney Liner & Rebuild Services in Fort Washington
Stainless Steel Liner Installation
Stainless steel liners are our most common solution for Fort Washington’s pre-WWII chimneys. The tall exterior masonry stacks on Bethlehem Pike colonials and Whitemarsh Township estates often contain original clay tiles that are cracked, undersized, or missing entirely - especially in homes built before the 1940s NFPA flue-liner standards. We install DuraFlex stainless steel liners precisely sized to each flue, whether it’s serving a wood fireplace, a converted oil furnace, or a gas boiler. A properly sized liner prevents dangerous heat transfer to combustible framing and corrects draft problems that cause smoke to back up into living rooms. Most stainless steel liner installations in Fort Washington run $2,800-$4,500 for a single flue, with multi-flue stacks running higher.
Flexible Liner Solutions
Flexible liners solve access problems in Fort Washington’s older chimneys with offset flues or corbeled throats. The antique chimney configurations in some pre-colonial-revival farmhouses - rubble-stone interiors, no dampers, shifted flue paths - make rigid liners impossible to install without extensive demolition. A flexible liner navigates these obstacles while still providing a sealed, properly sized vent path. We use professional-grade flexible products from trusted manufacturers, never builder-grade substitutes. Flexible liner installation in Fort Washington typically costs $3,200-$5,000 depending on flue complexity and access.
Liner Replacement
Liner replacement becomes necessary when existing liners have deteriorated beyond repair. In Fort Washington, we see this most often in chimneys where original clay tiles have spalled from decades of freeze-thaw cycling, or where a previous owner installed an improperly sized liner for a converted heating system. Our Level-2 camera inspection documents the exact condition before we recommend replacement versus repair. We remove the failed liner, inspect the surrounding masonry, and install a new system matched to your appliance and fuel type. Liner replacement in Fort Washington generally ranges from $3,500-$6,000.
Partial Chimney Rebuild
Partial rebuilds address damage confined to the upper chimney - the crown, top courses of brick, and flue opening. This is common in Fort Washington where winter freeze-thaw cycles attack exposed chimneys mercilessly. The soft historic brick and lime mortar in Whitemarsh Township’s 1910s-1950s homes simply cannot withstand dozens of cycles per season without spalling and cracking. We rebuild from the roofline up using matching brick and proper mortar composition, install a new crown with correct slope and overhang, and cap it to keep debris from the Wissahickon Valley canopy out. Partial rebuilds in Fort Washington typically run $4,500-$7,500.
Full Chimney Rebuild
Full rebuilds are reserved for chimneys where structural integrity has failed throughout - leaning stacks, widespread mortar deterioration, or internal fire damage that compromises the entire system. In Fort Washington’s oldest estates, we’ve encountered chimneys where 100-year-old lime mortar has turned to sand and the stack threatens to separate from the house. We dismantle carefully, salvage matching brick where possible, and rebuild to modern standards while preserving the architectural character your home requires. Full chimney rebuilds in Fort Washington range from $8,000-$15,000+ depending on height, brick matching, and complexity.

Common Chimney Liner & Rebuild Problems We See in Fort Washington Homes
- Original clay-tile liners are undersized or missing. Pre-1940s homes throughout Fort Washington were built before NFPA flue-liner standards, meaning many chimneys lack properly sized liners or contain degraded tiles that no longer protect combustible framing. We find this on nearly every inspection in the colonial-revival neighborhoods off Bethlehem Pike.
- Freeze-thaw cycles destroy historic mortar and brick. Philadelphia-region winters put Fort Washington through repeated freeze-thaw cycles that spall soft historic brick and crumble lime mortar joints. Crown cracks follow, allowing water infiltration that accelerates deterioration from the top down. This pattern is especially severe on exposed chimneys in the open areas near Fort Washington State Park.
- Multi-flue stacks create liner-sizing mismatches and cross-draft. Single chimney stacks with two or three active flues were standard in pre-WWII Montgomery County construction. A wood fireplace flue, a converted oil furnace flue, and sometimes a boiler flue all venting through one masonry structure creates draft interactions that standard single-flue solutions cannot address. Each flue needs its own properly sized liner.
- Autumn debris accumulation from dense tree canopy. The neighborhoods bordering Fort Washington State Park and the Wissahickon Valley corridor collect heavy leaf and twig deposits in chimney tops each fall. Without a proper cap, this debris traps moisture against the crown and flue opening, accelerating decay and creating fire hazards.

What moves a job toward the higher end: multiple flues requiring separate liners, difficult access on tall chimneys, brick matching for visible elevations, and extensive mortar repointing below the rebuild zone. What keeps costs controlled: catching problems early through regular Level-2 inspection, addressing crown cracks before water damages the full stack, and choosing partial rebuild over full rebuild when structural integrity below the roofline remains sound.

FAQs - Chimney Liner & Rebuild in Fort Washington
Pre-WWII Montgomery County builders commonly combined multiple flues into a single masonry chimney to save materials and exterior wall space. Your wood fireplace, converted oil furnace, and possibly a boiler all originally vented through separate flue passages within one stack. This was standard construction then, but it creates liner-sizing mismatches and cross-draft issues that modern standards prohibit. We install separate, properly sized liners for each active flue to eliminate smoke backup and ensure safe draft. Call (866) 580-4069 for an inspection - estimates are free.
Most Fort Washington chimneys with freeze-thaw damage need only a partial rebuild from the roofline up, provided the masonry below remains structurally sound. We determine this through Level-2 camera inspection and physical assessment of the stack. If the lower chimney shows intact mortar, no leaning, and no internal fire damage, we rebuild the crown and upper courses, install proper flashing, and cap against debris. Full rebuild becomes necessary only when damage extends throughout the structure. Call (866) 580-4069 - we’ll show you the photos and give you a straight answer.
A 1920s fieldstone chimney with rubble-stone interior and possible flue offsets typically requires a flexible stainless steel liner rather than a rigid system. Rigid liners cannot navigate the irregular interior geometry without destructive masonry removal. We use DuraFlex flexible liners sized precisely to your appliance and fuel type, installed with proper insulation to meet manufacturer warranty requirements. The flexible liner seals the flue path while preserving your historic chimney structure. Most fieldstone installations in Fort Washington run $3,200-$5,000. Call for an exact quote - estimates are free.
We install copper or stainless steel chimney caps with proper mesh screening that blocks leaves and twigs from the Wissahickon Valley canopy while maintaining adequate draft. If your crown is already damaged from years of debris accumulation, we repair or rebuild it as part of the capping installation. Annual inspection catches cap displacement or mesh clogging before it becomes a blockage hazard. The combination of proper cap and regular maintenance eliminates the debris problem. Call (866) 580-4069 to schedule - estimates are free.
Yes. Oil furnaces require larger flue diameters than modern gas appliances, and your existing flue was almost certainly sized for the original oil burner. The oversized flue creates sluggish draft with lower-temperature gas exhaust, allowing smoke and combustion gases to spill into your living space. We see this constantly in Fort Washington’s converted pre-WWII homes. The solution is a properly sized liner - typically a smaller diameter stainless steel system - that creates correct draft velocity for your new appliance. This is safety-critical work; gas spillage can introduce carbon monoxide into your home. Call (866) 580-4069 today for immediate inspection.
