Why Hearthstone Chimney Co. of Philadelphia Is Lansdale’s Preferred Chimney Liner & Rebuild Company
Forty-two years in this trade means we’ve worked on Lansdale chimneys through three fuel transitions: coal to oil, oil to gas, and now the occasional heat-pump hybrid. That history matters because the borough’s housing stock carries the scars of each conversion. In the attached row homes near Lansdale Station, we regularly encounter flues that were sized for coal grates and never properly relined when the boiler switched to gas. The flue is too big, the draft is wrong, and condensation eats the mortar from the inside out. We’ve seen it hundreds of times.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the flue is cracked, we show you the crack. If the liner is missing entirely, we document the bare brick. Our 90-Day Done Right Promise covers every job in writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. values: Krafted right, Every time, Your home first, Standing behind it.
Our background-checked, uniformed technicians complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. We’ve built our reputation in Lansdale one chimney at a time, and we plan to be here for another thirty years.
Our Chimney Liner & Rebuild Services in Lansdale
Stainless Steel Liner Installation
A stainless steel liner is the correct fix for most Lansdale chimneys that were built unlined or have deteriorating clay tile. We install DuraFlex stainless steel liners sized precisely for your appliance, whether it’s a gas boiler, oil furnace, or wood-burning fireplace insert. In Lansdale’s older homes, especially the twins and row homes between Main Street and the rail corridor, the original flue is almost always oversized for modern equipment. A properly sized stainless liner corrects the draft, eliminates condensation, and brings the system into compliance with current NFPA 211 standards. Most stainless liner installations in Lansdale run $2,800-$4,200 for a straight flue, with multi-story or offset flues toward the higher end.
Flexible Liner Retrofit
Not every Lansdale chimney is straight. The Victorians with their offset flues and the row homes with their tight chase enclosures often need a flexible liner that can navigate bends without tearing. We use DuraFlex flexible stainless products for these applications, installed with minimal disruption to finished interiors. If your home is one of the attached twins near Lansdale Station with a shared party-wall chimney, flexible liner installation requires extra care to isolate each flue properly. We’ve done this work dozens of times in 19446, and we know how to protect both your home and your neighbor’s during the process.
Liner Replacement
When an existing liner has failed, partial replacement sometimes works. More often, in Lansdale’s climate, we find the damage extends further than the homeowner expected. Southeastern Pennsylvania’s freeze-thaw cycles, with temperatures crossing 32°F repeatedly each winter, force water into hairline cracks that expand and contract until the liner is spalling and the surrounding brick is compromised. We remove the failed liner, inspect the surrounding masonry with our camera, and recommend either a targeted replacement or a full rebuild based on what we find. No guesswork. Photos you can see, a plain-English verdict.
Partial Chimney Rebuild
A partial rebuild addresses the section of chimney that has failed while preserving sound masonry below. In Lansdale, this most commonly means rebuilding from the roofline up, replacing spalled brick, deteriorated mortar, and a cracked crown that has let water infiltrate for years. The Victorians near Broad Street and the early-20th-century colonials off Valley Forge Road are frequent candidates for this work. Their brick was fired locally and is often softer than modern hard-fired brick, making it more vulnerable to freeze-thaw damage. A partial rebuild in Lansdale typically runs $3,500-$6,000, depending on height, accessibility, and whether we’re also installing a new liner through the rebuilt section.
Full Chimney Rebuild
When the damage extends below the roofline, or when the chimney has suffered years of deferred maintenance, full rebuild is the only safe option. We’ve completed full rebuilds on Lansdale homes where the original coal-era chimney was never maintained through the oil and gas transitions, and the masonry was essentially hollowed out by condensation and freeze-thaw cycling. A full rebuild removes the existing stack to the roofline or below, reconstructs with matching brick where possible, and integrates a new stainless steel liner sized for your current appliance. Full rebuilds in Lansdale range from $6,500-$8,500 for a typical residential chimney, with complex heights or historical matching requirements adding to the scope.

Trusted Brands We Service in Lansdale
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, and Famco, among others, so we’re not ordering parts and making you wait. DuraFlex stainless liners handle the acid condensation produced by modern gas appliances in oversized flues. HeatShield cerfractory sealant restores deteriorated clay tile when the tile is sound enough to save but porous enough to leak. Famco chimney caps and accessories finish the job with hardware that lasts. For Lansdale homeowners, this means most jobs start and finish the same day, and the materials we install are rated for the temperature swings and moisture exposure this climate delivers.
Common Chimney Liner & Rebuild Problems We See in Lansdale Homes
- Original unlined brick flues built for coal. The vast majority of Lansdale’s pre-1950 chimneys were never lined at all, or were lined with clay tile sized for coal-burning equipment. When those homes converted to gas, the flue became dangerously oversized. Combustion gases cool too quickly, condense into acidic moisture, and eat the mortar joints from the inside. We find this in twin homes off Walnut Street and row homes near the station weekly.
- Freeze-thaw destruction of crowns and mortar. Lansdale’s position in the freeze-thaw belt means every winter, water penetrates tiny cracks in the crown, expands when it freezes, and widens those cracks incrementally. By spring, the crown is spalling and water is running down inside the flue. The Victorians with their original soft brick suffer fastest.
- Shared party-wall chimney hazards. In the attached blocks near Lansdale Station, a single masonry stack often contains flues for two or more units. A cracked liner or blocked flue in one unit can push carbon monoxide into a neighbor’s living space. This isn’t theoretical. We’ve documented it. Liner inspection in these configurations is legally and safety-critical in ways that detached suburban chimneys simply aren’t.
- Deteriorated clay tile from acid erosion. Even where clay tile liners were installed, they weren’t designed for the acidic condensation produced by high-efficiency gas equipment. The tile spalls, flakes, and falls into the flue, creating blockages and exposing the surrounding brick to further damage. In Lansdale’s older housing stock, this is the norm, not the exception.

FAQs - Chimney Liner & Rebuild in Lansdale
Yes. In Lansdale’s attached housing near the SEPTA station, shared party-wall chimneys often contain multiple flues within a single masonry stack, and a cracked or missing liner in your flue can allow combustion gases to migrate through gaps in the separating wythe into your neighbor’s flue or living space. This is why Level-2 camera inspection is essential in these configurations, and why we document the condition of the full stack, not just your flue. If you suspect a liner problem, call (866) 580-4069 for a free inspection. Estimates are free, and we’ll explain exactly what we find.
A partial rebuild replaces masonry from the roofline up, preserving sound construction below; a full rebuild removes the stack to or below the roofline and reconstructures entirely. For Lansdale’s Victorian and early-20th-century chimneys, the critical factor is how far freeze-thaw damage and condensation have penetrated. We often find that damage visible at the crown has traveled much lower in soft, porous brick. Our camera inspection determines which approach is appropriate. Call (866) 580-4069 and we’ll show you what we see.
Because the flue was almost certainly built for coal, converted to oil, then converted to gas, with no liner installed during either transition. The flue is oversized for your gas appliance, producing acidic condensation that destroys mortar from the inside while the exterior looks intact. We’ve opened chimneys in Lansdale that appeared sound outside but had hollowed mortar joints and dangerous gas leakage inside. A stainless steel liner sized for your current equipment is the correct fix. Call (866) 580-4069 for a camera inspection that shows you the real condition.
Southeastern Pennsylvania’s winters repeatedly cross the freezing point, driving moisture into tiny cracks in crowns and mortar joints, then expanding that moisture as ice. Each cycle widens the crack incrementally. In Lansdale, where many chimneys are 80 to 140 years old with original soft brick and lime mortar, this process advances faster than in newer construction. Spalled brick, deteriorated crowns, and water infiltration into the flue are the direct results. The damage is often hidden until an inspection reveals it. Call (866) 580-4069 for a free estimate.
Almost certainly yes. Oil and gas produce different combustion profiles, and a flue sized for oil equipment is typically oversized for gas, leading to the condensation and acid erosion that destroys chimneys from the inside. In Lansdale’s twins and row homes, where the original flue was likely built for coal and already too large, the oil-to-gas conversion usually makes the mismatch worse. A properly sized stainless steel liner corrects the draft, eliminates condensation, and protects the masonry. Call (866) 580-4069 for an inspection and exact quote. Estimates are free.
