Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Liner & Rebuild Across Macungie
Chimney liner replacement and partial rebuilds in Macungie typically run $1,800-$4,500 depending on whether you have a factory-built metal chase system or a full masonry stack, and most jobs are completed in a single visit with our crew. If you live in Lower Macungie Township’s 1990s or 2000s subdivisions off Route 100 or Trexlertown Road, your zero-clearance fireplace likely has a manufacturer-specific metal liner that can separate at chase joints or corrode from freeze-thaw water intrusion long before the brickwork shows any wear. Call (610) 632-1394 and a live person will answer, 24 hours a day, to book your free estimate.
We’ve been dispatching crews to Macungie from our Philadelphia office for decades, and we’ve learned the local housing stock block by block. The borough’s Pennsylvania German masonry homes along Main Street and Chestnut Street need one approach. The subdivision homes near Windmill Lane, Spring Creek Road, or the Brookfield development need another entirely. Our Chimney Liner & Rebuild team carries both DuraFlex flexible liners for factory-built chases and HeatShield cerfractory flue sealant for aging masonry flues, so we’re equipped for whatever your Macungie chimney actually is.
Why Hearthstone Chimney Co. Is Macungie’s Preferred Chimney Liner & Rebuild Company
Homeowners in Macungie call us because we’ve earned a reputation for telling the truth about what a chimney actually needs. Our Level-2 camera inspections end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman. If your factory-built chase liner is intact, we say so. If it’s separated at a mid-chase joint and leaking smoke into your wall cavity, we show you the picture.
We’ve served local communities for over 42 years, and our 90-Day Done Right Promise is backed 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. Calls are answered by a live person, every hour of every day, not a voicemail queue.
Dispatch and scheduling are coordinated from our Philadelphia office, but our crews serve Macungie locally and know the difference between a borough masonry stack and a township prefabricated chase. That local knowledge saves time and prevents the wrong repair from being sold.
Our Chimney Liner & Rebuild Services in Macungie
Stainless Steel Liner Installation
For Macungie homeowners with aging masonry chimneys in the historic borough, a stainless steel liner is often the right path when clay tile flues have cracked from decades of Lehigh Valley freeze-thaw cycles. We size the liner to your appliance, whether it’s a gas boiler, oil furnace, or wood-burning insert, and install it with proper insulation and top-sealing collars. A typical stainless steel liner installation in Macungie runs $2,200-$3,800 for a standard single-flue masonry chimney.
Flexible Liner Replacement
This is where we spend much of our time in Lower Macungie Township. Factory-built zero-clearance fireplaces from the 1990s and 2000s were installed with manufacturer-specific metal liners that can separate at joints, corrode, or be sized incorrectly for a new appliance. Our flexible DuraFlex liners are custom-cut and fitted to the appliance manufacturer’s specifications, then secured at the firebox and chase cap with proper termination clearances. A flexible liner replacement in Macungie’s subdivision homes typically costs $1,800-$3,200.
Liner Replacement for Prefabricated Chase Systems
A chimney that looks brand-new from the roof can be failing inside. In Macungie’s newer developments, we regularly find chase caps with failed sealant and corroded fasteners letting water rust the liner from the outside in. We replace the liner, re-secure or replace the chase cap with a Gelco or Olympia Chimney product sized to the chase, and re-test draft before we leave. Liner replacement with chase cap service in Macungie generally runs $2,000-$3,500.
Partial Rebuild of Masonry and Chase Components
When a Macungie masonry chimney has spalling brick, deteriorated crown, or a compromised top section but sound lower structure, we perform partial rebuilds rather than pushing a full rebuild you don’t need. We match mortar composition to the existing Pennsylvania German construction, replace damaged brick with compatible units, and install a proper concrete crown with drip edge. Partial rebuilds in Macungie start around $2,800 and range to $4,500 for more extensive top-section work.

Trusted Brands We Service in Macungie
We work exclusively with professional-grade materials from industry-trusted brands. For Macungie’s factory-built chase systems, we stock DuraFlex flexible liners and specify Gelco and Olympia Chimney chase caps and termination components for fast turnaround. For masonry flue restoration, we use HeatShield cerfractory sealant when the clay tile is sound but cracked, and Famco termination fittings where specified. No builder-grade substitutes. These are the same parts we’d put in our own homes.
Common Chimney Liner & Rebuild Problems We See in Macungie Homes
- Factory liner separated at mid-chase joint. In Lower Macungie Township subdivisions, the original metal liner on zero-clearance fireplaces often pulls apart at factory joints after years of thermal cycling. Smoke leaks into the chase cavity instead of exiting through the cap, and homeowners notice a smoky smell after the fireplace has been running for an hour.
- Chase cap sealant failure letting water rust the liner. The Lehigh Valley’s repeated freeze-thaw cycles attack the sealant and fasteners on prefabricated chase caps. Water enters, pools in the chase, and corrodes the metal liner from the outside. By the time you see a stain on the ceiling, the liner may already be compromised.
- Oversized flue from coal-to-gas conversion. In Macungie borough’s older homes, chimneys built for coal furnaces have flue cross-sections far too large for modern gas inserts or wood stoves. The draft never establishes properly, and creosote builds up on the oversized flue walls. A properly sized liner is the only fix.
- Displaced liner discovered only when adding an appliance. Macungie homeowners with newer homes often skip annual inspections, assuming a 2005 build date means nothing can be wrong. Then they install a wood stove or gas insert and discover the factory liner is degraded or missing sections. We inspect first, reconnect second.

FAQs - Chimney Liner & Rebuild in Macungie
Yes. Factory-built zero-clearance fireplaces in Macungie’s 2000s subdivisions can have separated metal liners, corroded chase caps, or degraded firebox refractory panels even without regular use. Gas appliances produce moisture and combustion byproducts that affect the liner, and the Lehigh Valley’s freeze-thaw cycle attacks chase components year-round. A Level-1 inspection takes about 45 minutes and confirms whether your system is intact before you add any appliance or start burning. Call (610) 632-1394 to schedule - estimates are free.
Cleaning removes creosote and debris, but it cannot repair a separated metal liner, an incorrectly sized flue, or a rusted chase component. In Lower Macungie Township’s subdivision homes, the factory liner is a sealed system engineered to specific tolerances. Once it fails, no amount of sweeping restores the barrier between combustion gases and your home’s structure. We document the damage with camera photos, explain the repair, and replace only what is necessary. Call (610) 632-1394 for an exact quote - estimates are free.
Most prefabricated chase chimneys can be partially rebuilt or component-replaced without removing the entire structure. We often replace chase panels, install a new DuraFlex liner, and fit a new Gelco or Olympia Chimney cap while preserving the existing firebox and framing. A full teardown is rare and usually only necessary after extensive fire damage or prolonged water infiltration. We inspect with a camera before recommending any scope of work. Call (610) 632-1394 for a free evaluation.
A Level 1 inspection is a visual examination of accessible components - the firebox, damper, and chase cap - appropriate for annual maintenance on a system with no known changes. A Level 2 inspection adds internal camera scanning of the flue liner, inspection of the attic and crawl space around the chase, and evaluation of clearances to combustibles. For Macungie’s factory-built fireplaces, we recommend Level 2 before any appliance change, after a chimney fire or suspected liner separation, or if you’re buying a home and the chase history is unknown. Call (610) 632-1394 to book - we’ll recommend the right level for your situation.
South Mountain, rising directly south of Macungie borough, can redirect prevailing winds and create intermittent downdraft conditions that force smoke back into the home. A properly sized and insulated liner improves draft velocity and reduces the chance of smoke rollout, but severe downdraft may also require a cap designed to deflect wind or, in rare cases, a chimney height adjustment. We test draft under varying conditions and recommend the right combination of fixes. Call (610) 632-1394 - we’ll diagnose your specific Macungie draft problem.
