The chimneys in Allentown’s older neighborhoods, from West End to the Historic District, were built for coal and later adapted for oil and gas. Many still run with unlined brick flues or clay liners that have cracked after decades of freeze-thaw cycles. We’ve pulled failed liners out of homes near Cedar Creek Park and rebuilt chimney stacks in the 18104 zip that had deteriorated to the point of leaking carbon monoxide into bedrooms. For homeowners looking for Chimney Liner & Rebuild - Allentown specialists, our local experience matters. Our Level-2 camera inspection ends with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. No recommendation for liner work or masonry rebuild comes without evidence you can examine yourself.

We’re not a one-truck operator chasing the next job, and we’re not a franchise sending commission-driven salespeople to your door. Hearthstone Chimney Co. is led by Russell Haines, and we’ve spent over 42 years building a company that plans to be in Allentown thirty years from now. That changes how we work. Our 90-Day Done Right Promise is in writing, with no arguing - if it’s not right, we come back. Our technicians are background-checked and uniformed, and most jobs are completed in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.

What Our Chimney Liner & Rebuild Service Includes

Stainless Steel Liner Installation

A stainless steel liner is a continuous metal tube inserted down your existing flue to create a sealed, properly sized passage for smoke and gases. In Allentown, we install stainless steel liners most often in homes built before 1940 with unlined brick chimneys, or where clay tile liners have cracked or shifted. Our crews use DuraFlex and Olympia Chimney stainless steel products, sized precisely to your appliance’s BTU output and your chimney’s interior dimensions. We pull a permit when required by Allentown city code, and every installation is pressure-tested and documented with before-and-after camera footage.

Flexible Liner Installation

Flexible liners are corrugated stainless steel tubes that navigate offset flues, chimney bends, and other irregularities that rigid pipe cannot follow. We recommend flexible liners in Allentown’s hillside homes, particularly in the slopes above Lehigh Parkway where chimneys were often built with offsets to accommodate steep grades. We also provide Chimney Liner & Rebuild - Coplay and nearby communities with the same flexible liner solutions. Our technicians carry DuraFlex flexible liner inventory on most trucks, which means we can often measure, cut, and install in one visit rather than ordering materials and returning. The flexibility also absorbs thermal expansion better than rigid alternatives in Allentown’s climate, where winter temperature swings stress fixed joints.

Liner Replacement

Liner replacement becomes necessary when your existing liner, whether clay tile, aluminum, or older stainless steel, has failed beyond repair. In Allentown, we see this most often in homes that converted from oil to gas without updating the liner diameter, or where original clay liners have spalled after decades of condensation exposure. We remove the failed liner completely, inspect the surrounding masonry with our camera system, and install a new liner matched to your current heating appliance. Every replacement includes a written condition report on the chimney structure itself, because a new liner in a deteriorating chimney is money wasted.

Partial Chimney Rebuild

A partial rebuild addresses specific sections of chimney failure - typically the crown, the top several courses of brick, or a damaged flue wall - without dismantling the entire structure. In Allentown, partial rebuilds are common in homes where the chimney crown cracked and water infiltrated the top courses, but the lower structure remains sound. We match existing brick and mortar where possible, and we use Gelco crown-forming materials and Copperfield flashing components to seal the repair against future water intrusion. Russell Haines has specified partial rebuilds for hundreds of Allentown homes where a full rebuild would have been unnecessary expense.

Full Chimney Rebuild

A full chimney rebuild is required when structural integrity has failed throughout the stack - extensive spalling brick, shifted or leaning construction, or multiple flue failures that compromise safety. We’ve completed full rebuilds on Allentown homes in the 1st and 6th Wards where century-old chimneys had simply reached end of service life. Our crews dismantle to the roofline or below, salvage usable materials where appropriate, and reconstruct with new brick, block, or pre-engineered components depending on the application. Every full rebuild includes a new liner system, proper clearance to combustibles per current code, and our 90-Day Done Right Promise in writing.

Liner Repair

Liner repair addresses isolated damage - small cracks, joint gaps, or surface deterioration - without full replacement. We use HeatShield cerfractory sealant, a refractory compound that restores the smooth, continuous surface your flue needs to draft properly and resist creosote buildup. This is appropriate for Allentown homeowners whose liners show early-stage wear but retain structural integrity, particularly in chimneys serving gas appliances where temperatures are moderate. We camera-inspect after every repair to verify complete coverage, and we tell you plainly when repair is a temporary measure versus a lasting solution.

Brands We Service for Chimney Liner & Rebuild

We’ve installed and serviced DuraFlex liners in hundreds of Allentown-area homes, from the ranch houses built during the 1950s expansion to the stone colonials in Salisbury Township. DuraFlex’s corrugated stainless construction handles our region’s thermal cycling well, and we stock multiple diameters so we’re not delaying your job for a parts order. Our technicians are familiar with DuraFlex’s specific termination requirements and have resolved draft issues in installations where other companies used incompatible connectors.

HeatShield’s cerfractory resurfacing system is our go-to for liner repair in Allentown chimneys where the clay tile is sound but the surface has degraded. We’ve applied HeatShield in homes near Trexler Park and along Hamilton Boulevard where homeowners wanted to preserve original construction while meeting modern safety standards. Gelco’s stainless steel and galvanized components round out our inventory for cap, crown, and flashing work that protects the liner investment below. Whether you have DuraFlex, HeatShield, Gelco, Olympia Chimney, or any other make currently installed, we can inspect it, repair it, or replace it with the right component for your system.

Signs You Need Chimney Liner & Rebuild Right Now

• White staining or efflorescence on exterior brick indicates moisture moving through the chimney structure, which accelerates freeze-thaw damage in Allentown’s winters. We see this frequently on north-facing exposures in neighborhoods like Rittersville, where sun doesn’t dry the masonry. Left unaddressed, the water intrusion destroys mortar joints from the inside out.
• Flakes of clay tile in your fireplace or cleanout mean your liner is spalling - shedding pieces of its interior surface into the flue. This reduces draft efficiency and creates obstruction hazards. In Allentown’s older housing stock, we’ve pulled handfuls of tile fragments from flues that appeared fine from the top.
• Smoke or odors entering your living space signal liner failure, blockage, or improper sizing for your current appliance. Carbon monoxide can accompany these symptoms and cannot be detected without a CO alarm. If you’re experiencing this, stop using the appliance and call us for a camera inspection.
• Visible cracks in the chimney crown or missing mortar between bricks allow water directly into the structure. Allentown’s freeze-thaw cycles - particularly the wet winters followed by sudden cold snaps - turn small cracks into structural failures within a season or two. Crown repair is far less costly than rebuilding the stack below it.
• Your heating appliance was changed but your liner wasn’t - oil-to-gas conversions are common in Allentown, and gas appliances require different liner materials and diameters than oil. An improperly sized liner causes condensation, corrosion, and eventually failure. We inspect these conversions regularly and find mismatched liners in roughly one of every three.

Our Chimney Liner & Rebuild Process - Step by Step

1. 1
   Schedule and initial consultation. Call (610) 632-1394 and a live person answers, 24 hours a day. We’ll ask about your chimney’s age, your heating appliance type, and what symptoms you’ve noticed. We schedule Level-2 inspections within a few days in Allentown, or sooner if you’ve stopped using the system due to safety concerns.
2. 2
   Level-2 camera inspection. Our technician arrives in a marked vehicle, uniformed and background-checked. We run a high-resolution camera the full length of your flue, recording every surface. You see the footage in real time on our monitor. We document cracks, gaps, creosote buildup, and structural conditions with photos you can keep. No recommendation follows without this evidence.
3. 3
   Plain-English verdict and written estimate. Russell Haines established our standard: explain the finding, explain the fix, explain the cost, then stop talking. Your estimate lists each line item - liner material, masonry work, permits, disposal - with no-hassle upfront pricing. The number on the estimate is the number on the invoice. We note anything that can safely wait, and we never pressure for immediate decisions.
4. 4
   Permits and scheduling. When Allentown requires permits for liner installation or structural rebuild, we pull them. We don’t ask homeowners to navigate city hall. Most liner installations and partial rebuilds are completed in a single visit. Full rebuilds typically require two to three days depending on weather and material curing requirements.
5. 5
   Installation, testing, and documentation. We install using professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. Every liner is pressure-tested or smoke-tested per manufacturer specification. We run a final camera pass to verify proper placement. You receive photos, test results, and your 90-Day Done Right Promise in writing before we leave.
