Lansdowne developed almost entirely as a Philadelphia streetcar suburb between roughly 1885 and 1925, meaning the vast majority of chimneys in the borough are over 100 years old and were originally built for coal combustion. When homeowners converted to oil or gas heat in the mid-20th century, those coal-era clay flue tiles - already undersized for modern appliances and cracked from a century of freeze-thaw cycling - were rarely relined, making Lansdowne an unusually high-density market for flue liner inspection and repair alongside every routine cleaning. We see this pattern on nearly every call to the 19050 zip code.
Why Hearthstone Chimney Co. of Philadelphia Is Lansdowne’s Preferred Chimney Liner & Rebuild Company
We’ve been serving Lansdowne and the surrounding Delaware County boroughs since 1984 - over 42 years - and we’ve learned the local brick, the local mortar, and the local building patterns house by house. Our technicians know the difference between a Lansdowne twin built in 1895 and one built in 1920, and they know where the flues tend to fail in each.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your liner is cracked, we show you the crack. If it’s sound, we tell you so.
Calls are answered by a live person, 24/7 - not a voicemail tree, not a callback queue. Most jobs are completed in a single visit by background-checked, uniformed technicians. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice. And every job is backed by the 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we come back.
We recently rebuilt a shared stack in a twin on Windom Avenue where a century-old clay liner on one side had collapsed from freeze-thaw spalling, blocking the flue and backdrafting into the neighbor’s living room. We installed a DuraFlex stainless steel liner on the affected side and patched the opposite flue crown, restoring safe venting for both families in one visit. That’s the kind of local knowledge you earn from decades in Lansdowne.
Our Chimney Liner & Rebuild Services in Lansdowne
Stainless Steel Liner Installation
A stainless steel liner is the standard repair for Lansdowne’s deteriorated clay flue tiles. We use DuraFlex and other professional-grade materials, sized precisely for your appliance - whether that’s a gas furnace, boiler, or water heater. In Lansdowne’s oversized flues from mid-century oil-to-gas conversions, a properly sized stainless liner restores draft and eliminates the carbon monoxide risk that comes with an unlined or oversize flue. Most stainless installations in 19050 run $2,800-$4,200 and are completed in one day.
Flexible Liner Systems
Some of Lansdowne’s older chimneys have offsets or bends that rigid pipe can’t navigate - common in the foursquares and rowhomes near Lansdowne Avenue. A flexible liner system threads through these irregular passages without breaking into walls. We size and install these with the same precision as rigid systems, and we document the full flue path with camera footage so you see exactly what was done.
Liner Replacement & Liner Repair
Not every damaged liner needs full replacement. Hairline cracks in otherwise sound clay tile can sometimes be addressed with HeatShield cerfractory flue sealant, a repair that restores the flue surface without removing the existing structure. We evaluate this honestly - if the tile is too far gone, we’ll tell you. If a repair will last, we’ll tell you that too. In Lansdowne’s 100+ year-old chimneys, we find that roughly half the calls for “liner replacement” actually need targeted liner repair instead, saving the homeowner significant cost.
Partial & Full Chimney Rebuild
When the brick stack itself has failed - spalling, leaning, or mortar washed out from decades of freeze-thaw - liner work alone won’t solve the problem. The Philadelphia-area freeze-thaw pattern, with temperatures crossing 32°F repeatedly from November through March, accelerates spalling and mortar joint erosion in Lansdowne’s century-old brick stacks. We rebuild from the roofline up (partial) or from the foundation (full), matching existing brick and mortar where possible. A typical partial rebuild on a Lansdowne twin home runs $4,500-$6,800; full rebuilds on detached homes range $7,000-$12,000. Post-winter inspections are especially important for catching crown and joint damage before the next heating season.

Trusted Brands We Service in Lansdowne
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - no builder-grade substitutes. These are the brands that professional sweeps and rebuilders have relied on for decades, and we stock common liner diameters and repair components so Lansdowne customers aren’t waiting on special orders. When we quote a job in the 19050 zip code, the parts are typically already on our truck or available next-day from our Philadelphia supply house.
Common Chimney Liner & Rebuild Problems We See in Lansdowne Homes
- Coal-era clay tiles fractured by freeze-thaw cycling. Lansdowne’s 100+ year-old chimneys were built with clay flue tiles sized for coal combustion. Decades of Philadelphia-area freeze-thaw cycles have cracked these tiles, creating pathways for carbon monoxide and moisture to escape into walls and living spaces.
- Oversized flues from oil-to-gas conversions. When Lansdowne homeowners switched to gas heat in the 1950s-1970s, the flues - originally sized for coal - became too large in diameter for efficient gas appliance venting. Without a properly sized stainless steel liner, these flues produce poor draft and elevated carbon monoxide risk.
- Shared-stack issues in twin homes. In Lansdowne’s abundant twin homes, a single chimney stack often serves both sides of the party wall through separate flue tiles. A deteriorated liner or blocked flue on one unit directly endangers the neighbor’s system. We always flag this shared-stack dynamic to both homeowners simultaneously - a conversation that rarely comes up in neighborhoods built after WWII.
- Spalling brick and eroded mortar from crown failure. Water enters through cracked crowns, freezes, and pops off brick faces. By March, we’re scheduling rebuilds on Lansdowne chimneys that looked fine in October. Catching crown damage early - with a post-winter inspection - often means the difference between a $400 crown repair and a $6,000 rebuild.

FAQs - Chimney Liner & Rebuild in Lansdowne
Yes, and we handle that coordination for you. In Lansdowne’s twin homes, a single chimney stack serves both units through separate flue tiles, so a liner failure on one side can backdraft into the neighbor’s living space. We notify both homeowners simultaneously, inspect both flues with our camera system, and schedule work that restores safe venting for both families - often in a single visit. Call (866) 580-4069 and we’ll walk you through the process; estimates are free.
Almost certainly yes. Lansdowne’s coal-era clay flue tiles are undersized for modern gas appliances and frequently cracked from a century of freeze-thaw cycling. An unlined or improperly lined flue venting a gas furnace poses a carbon monoxide risk and violates current code. We inspect with a Level-2 camera, show you the actual condition of your tiles, and recommend either liner repair or full stainless steel replacement based on what we find. Call (866) 580-4069 for a free inspection.
Spalling - the flaking and popping of brick faces - is caused by water entering through cracked crowns or failed mortar joints, then freezing and expanding during Lansdowne’s repeated winter freeze-thaw cycles. A rebuild removes the damaged brick and restores the structural shell, but we also address the water entry point with a proper crown, cap, and flashing detail so the problem doesn’t repeat. Post-winter inspections in March and April catch this damage before the next heating season. Call (866) 580-4069 to schedule.
In most cases, yes. We thread stainless steel or flexible liners down the existing flue without disturbing the surrounding brick. For Lansdowne’s Victorian and Edwardian-era homes - many on the National Register or in local historic districts - this preserves exterior character while bringing venting up to modern safety standards. We document the full installation with camera footage so you have a record of the work. Call (866) 580-4069 to discuss your specific chimney.
We typically inspect same-day or next-day for Lansdowne calls, and most rebuilds are scheduled within one week of estimate approval. Emergency situations - a leaning stack, visible collapse, or carbon monoxide alarm tied to flue failure - get priority response. A live person answers our phones 24 hours a day, 7 days a week. Call (866) 580-4069 and we’ll get you on the schedule.
