Russell Haines built Hearthstone Chimney Co. on a straightforward idea: show the homeowner what the camera sees, explain what it means in plain English, and price the job upfront before any work begins. No paperwork games, no arguing if something needs correction. Our 90-Day Done Right Promise covers every liner and rebuild job in writing.

Bath’s chimneys are not generic. The borough’s compact historic core is packed with pre-1920 Pennsylvania German masonry homes whose original flues were built with local limestone-based mortars that spall aggressively under the Lehigh Valley’s sharp freeze-thaw cycling. Moore Township’s surrounding farmland adds 19th-century farmhouses with massive central chimney stacks designed to serve multiple flues simultaneously. These are not suburban chimneys, and they do not respond well to suburban repair templates.

Why Hearthstone Chimney Co. Is Bath’s Preferred Chimney Liner & Rebuild Company

We’ve worked on Bath chimneys long enough to recognize the borough’s two signature problems on sight. In the older streets near the center, original fireplaces sealed or converted to oil and gas in the 1950s and 60s left clay flue tiles - or bare unlined brick - sitting dormant for decades. Now that pellet and wood-insert retrofits are surging across Northampton County, our Fireplace Services in Bath routinely uncover cracked or missing liner sections that owners had no idea existed. We document everything with a Level-2 camera inspection. The homeowner sees the footage. We explain what it means. Then we price the fix.

Our reputation in Bath and the surrounding Lehigh Valley has been built one job at a time since 1984. Background-checked, uniformed technicians arrive when scheduled. Most liner and partial rebuild jobs finish in a single visit. The number on your estimate is the number on your invoice. If we don’t get it right, we come back and make it right - in writing, no arguing, governed by our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it.

Dispatch and scheduling for Bath are coordinated from our Philadelphia office, but our crews serve the area locally and understand the specific failure modes of limestone-mortar construction and multi-flue farmhouse stacks. We’re not learning Bath’s housing stock on your dime.

Our Chimney Liner & Rebuild Services in Bath

Stainless Steel Liner Installation

A stainless steel liner is the right choice for most Bath homeowners with a damaged clay flue or an unlined brick chimney that needs to vent a modern appliance safely. We install DuraFlex and other professional-grade stainless systems sized precisely to your appliance’s output and your chimney’s interior dimensions. In Bath’s older row homes, this often means dropping a liner through a narrow, offset flue that was never designed for the BTU load of a contemporary wood insert. We measure twice and fabricate custom top plates when needed. The result is a liner that drafts correctly, contains creosote safely, and meets current NFPA 211 standards without disturbing historic exterior brickwork.

Flexible Liner

Flexible liners are our most common recommendation for Bath’s pre-1920 chimneys, and for good reason. The offset flues in borough center row homes - built with rough interior brick and sudden directional changes - often won’t accept a rigid stainless insert without destructive masonry removal. A flexible DuraFlex liner navigates these offsets while maintaining the full cross-sectional area needed for proper draft. We’ve installed flexible liners in Bath chimneys where the flue bends twice between the smoke chamber and the crown, jobs that rigid systems simply cannot handle. The flexible wall also accommodates the thermal expansion and contraction that Bath’s five-month heating season demands, reducing stress at connection points.

Liner Replacement

Liner replacement in Bath is rarely a simple swap. In the borough core, we regularly find original clay tiles that have been partially removed, cracked by freeze-thaw spalling, or coated with third-degree creosote glazing that a standard brush cannot touch. Our process starts with a full camera inspection. We show you the cracked tiles, the missing sections, the glazed buildup. Then we remove the damaged liner - sometimes in pieces, sometimes as dust - and install a new system appropriate to your appliance and fuel type. For homeowners in Moore Township farmhouses, liner replacement often involves separating flues that were never properly isolated, ensuring that exhaust from your living room insert does not migrate into a dormant cooking hearth flue.

Partial Rebuild

Partial rebuilds address the damage that liner installation alone cannot fix. In Bath, this typically means our Chimney Cap & Crown in Bath, the top courses of brick, or the smoke chamber above the damper. The Lehigh Valley’s repeated freeze-thaw crossings at 32°F destroy limestone-rich historic mortars, opening gaps that let water track down behind the flue and corrode any new liner from the outside in. We rebuild with compatible materials - not modern Portland cement slathered over historic brick - and we always inspect the interior with a camera before closing up. A partial rebuild without interior verification is a gamble we don’t take. Russell Haines has seen too many Bath homeowners pay twice for the same problem because someone skipped the camera.

Full Chimney Rebuild

Full rebuilds are uncommon but necessary when a Bath chimney has suffered catastrophic structural failure - typically from long-term water infiltration, foundation settling, or multiple flue fires that have cracked the masonry shell. We approach full rebuilds with the same documentation standard: photos, plain-English verdict, upfront pricing. Where possible, we salvage original brick that matches the home’s character. When we can’t, we source compatible replacements. The goal is a chimney that functions safely and looks like it belongs on your house.

Liner Repair

Some Bath chimneys need liner repair rather than full replacement. HeatShield cerfractory resurfacing can restore a clay flue with minor cracking or spalling, provided the structural shell remains sound. We assess candidly: if the camera shows through-wall cracks or significant tile displacement, repair is false economy and we’ll tell you so. Our 90-Day Done Right Promise means we have every incentive to recommend the right fix, not the easy sale.

Trusted Brands We Service in Bath

We work exclusively with professional-grade materials from industry-trusted manufacturers. For Bath liner jobs, we regularly specify DuraFlex flexible stainless systems, HeatShield cerfractory resurfacing products, and Copperfield chimney components. These are not builder-grade substitutes. We stock common diameters and fittings locally, which means faster turnaround for Bath homeowners and no waiting on back-ordered parts while your heating season slips away. Every brand we use has a track record in the Lehigh Valley’s freeze-thaw climate, and every installation is documented with photos you can see and a plain-English verdict you can understand.

Common Chimney Liner & Rebuild Problems We See in Bath Homes

• Bare-brick flues overfired by retrofitted inserts. Original single- or double-flue chimneys in Bath’s pre-1920 row homes were often never properly lined with clay tile. Retrofitting a wood or pellet insert quickly overfires the bare brick, driving third-degree creosote into mortar joints that were never meant to contain it. We catch this with camera inspection before the first fire of the season.
• Freeze-thaw destruction of limestone mortars. The Lehigh Valley’s continental climate delivers repeated crossings at 32°F throughout fall and spring. Bath’s historic limestone-based mortars spall under this cycling, opening gaps at the crown and flashing that let water track down to the smoke chamber. Any new liner installed without addressing this exterior damage will corrode from the outside in.
• Multi-flue farmhouse stacks inspected as single flues. Moore Township’s Pennsylvania German farmhouses contain massive central chimney stacks built for simultaneous cooking hearth, parlor stove, and summer kitchen flues. Standard single-flue inspection protocols miss cross-contamination between flues that share one masonry mass. We inspect every flue independently, with separate camera runs and documentation.
• Dormant flues reactivated without verification. Many homeowners in Bath’s older streets had fireplaces sealed or converted to oil and gas in the mid-20th century. The original clay flue tiles - or bare unlined brick - have sat unchecked for decades. Today’s pellet and wood-insert retrofits routinely expose cracked or missing liner sections that owners never knew existed. We find them before you burn.
