Our Chimney Liner & Rebuild Services in Philadelphia
Stainless Steel Liner Installation
Philadelphia’s rowhouses - especially in Brewerytown, Bella Vista, and Cedar Park - often share a common brick chimney stack with multiple flues that were originally sized for coal and never relined for gas, creating a chronic risk of cross-contamination and carbon monoxide seepage into adjacent units. We install DuraFlex flexible stainless steel liners sized precisely for your appliance, whether it’s a gas furnace, boiler, or fireplace insert. The smooth interior surface resists creosote buildup and handles the temperature swings of Philadelphia’s mid-Atlantic winters without cracking. Most installations in 1910s-1930s rowhouses run $2,200-$3,800 and are completed in one day.

Flexible Liner Systems
Tight flue passages in Philadelphia’s older masonry are exactly what flexible liners were designed for. We thread DuraFlex through offsets and corbeling that would defeat a rigid pipe, then top it with a proper termination cap. Flexible liners are particularly valuable in homes near the Delaware and Schuylkill river valleys where moisture has degraded mortar joints, making rigid alignment impossible. Typical flexible liner jobs in Philadelphia run $1,800-$3,200.

Liner Replacement
When clay flue tiles have cracked from decades of thermal cycling - or were never installed in the first place - liner replacement isn’t optional. In Philadelphia’s coal-conversion housing stock, we regularly find original coal flues left bare after gas conversion, now crumbling and leaking combustion gases into wall cavities. We remove the failed material, inspect with a camera, and install a new liner system that meets current NFPA 211 standards. Liner replacement in Philadelphia typically costs $2,000-$4,000 depending on flue height and access.

Partial Chimney Rebuild
Philadelphia’s freeze-thaw cycle - temperatures repeatedly crossing 32°F throughout winter - destroys aging lime-mortar joints in 100-year-old rowhouse chimney stacks. Spalling brick, deteriorated crowns, and corbeling damage often require partial rebuild rather than spot repair. We rebuild from the roofline up using matching brick and professional-grade Gelco crown sealer to stop water infiltration at its source. Partial rebuilds in Philadelphia generally run $3,500-$6,500, with most completed in two days.

Famco termination caps and Copperfield flashing materials are also in regular rotation for our Philadelphia jobs.

When you’re working on a 1920s rowhouse stack that needs to survive another century, that distinction matters.
Common Chimney Liner & Rebuild Problems We See in Philadelphia Homes
- Original coal-era flue left unlined after gas conversion. In older rowhouse blocks across Brewerytown and East Falls, we routinely open up fireplaces for renovation-era clients and discover that the original coal flue was never properly separated from the gas furnace flue - a shared-flue condition hidden behind decades of paint and plaster that is both a code violation and a carbon monoxide risk unique to the city’s coal-conversion history.
- Mortar joint spalling from Philadelphia’s river valley freeze-thaw cycles. Moisture from the Delaware and Schuylkill river valleys accelerates brick deterioration at the crown and corbeling, while repeated winter freeze-thaw cycling cracks flue tiles and opens pathways for water behind the brick.
- Shared flue between fireplace and furnace in pre-1940 rowhouses. Philadelphia’s signature two- and three-story brick rowhouses feature interior chimney stacks shared by party walls that serve multiple flues - one for the fireplace, one for the furnace or boiler. A single neglected chimney can affect draft for an entire heating system in a home with no exterior chimney access.
- Improperly sized flue for modern high-efficiency appliances. Coal-era flues are often too large for today’s gas furnaces, causing condensation that deteriorates masonry from the inside out - a problem we diagnose with our Level-2 camera inspection before any work begins.

FAQs - Chimney Liner & Rebuild in Philadelphia
You need a Level-2 camera inspection to confirm it - the condition is hidden inside the masonry and not visible from the fireplace or roof. In Philadelphia’s pre-1940 rowhouses, shared flues between coal-era fireplace flues and later gas furnace connections are common, especially in neighborhoods like Brewerytown and Bella Vista where coal-to-gas conversions were done cheaply in the 1950s-1970s. Our inspection includes photos you can see and a plain-English verdict on whether your flues are properly separated. Call (866) 580-4069 to schedule - estimates are free.
No - and we don’t recommend trying. Working inside a 100-year-old masonry flue involves real hazards: unstable brick, possible asbestos in old mortar, carbon monoxide exposure from disturbed gas connections, and the risk of creating a worse shared-flue condition. Philadelphia’s rowhouse chimneys also have tight offsets and party-wall construction that make proper liner sizing and termination technically demanding. Our background-checked technicians handle the inspection, sizing, installation, and code compliance. Call (866) 580-4069 for an exact quote.
Flexible stainless steel, specifically DuraFlex, is the best choice for Philadelphia’s climate and housing stock. It withstands our repeated freeze-thaw cycles, flexes through the offsets common in rowhouse chimneys, and resists the acidic condensation produced by modern gas appliances in oversized coal-era flues. Rigid stainless steel works for straight flues but is rarely suitable for Philadelphia’s older masonry. We stock DuraFlex on every truck for same-day installation.
Every year, without exception, if your home was built before 1940. Philadelphia’s coal-conversion rowhouses have legacy conditions - unlined flues, deteriorated mortar, hidden shared flues - that can deteriorate rapidly. The NFPA recommends annual Level-1 inspections for all chimneys, but we strongly advise Level-2 camera inspections every 12 months for pre-1940 Philadelphia homes, and immediately upon buying any rowhouse in neighborhoods like Northern Liberties, Nicetown-Tioga, or North Central. Call (866) 580-4069 to book your inspection.
Most Philadelphia rowhouses need liner work with spot masonry repair, not full rebuilds. We recommend full rebuild only when the structural integrity of the stack is compromised - extensive spalling through multiple wythes, leaning, or separation from the party wall. In a 1920s rowhouse on Montrose Street in Brewerytown, we opened a fireplace during a renovation and found the coal flue still connected to the gas furnace flue - a dangerous shared condition hidden behind decades of paint. We installed a DuraFlex flexible stainless steel liner to separate the gas furnace flue, then partially rebuilt the chimney crown with Gelco crown sealer to stop freeze-thaw water infiltration. The homeowner now has a code-compliant, safe system with no cross-contamination. Our Level-2 inspection with photos gives you the straight answer. Call (866) 580-4069 for a free estimate.
