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.

Why Hearthstone Chimney Co. Is Harleysville’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimneys along Ruth Road, near the intersection of Routes 63 and 113, and throughout the neighborhoods off Maple Avenue. Harleysville homeowners call us back because we document every inspection with photos they can see, deliver a plain-English verdict, and back every job with our 90-Day Done Right Promise in writing.
Our dispatch is coordinated from our Philadelphia office, but our technicians live in and around Montgomery County. They know that a home near the Perkiomen Creek faces different freeze-thaw stress than one in the newer developments off Orvilla Road. That local knowledge means we arrive with the right materials - DuraFlex stainless steel liners, HeatShield refractory mortar, factory-matched Gelco caps - instead of guessing.
Background-checked, uniformed techs. No-hassle upfront pricing. The number on the estimate is the number on the invoice. We’ve been doing it this way since 1984.
Our Chimney Liner & Rebuild Services in Harleysville
Stainless Steel Liner Installation
Most Harleysville homes with wood-burning fireplaces or inserts need a stainless steel liner to bring an unlined or deteriorated flue up to modern safety standards. We size and install DuraFlex liners to NFPA 211 code, pulling them through existing flues in fieldstone farmhouses or dropping them down prefabricated chases in 1970s colonials off Souderton Road. A properly sized liner protects against creosote buildup and carbon monoxide leakage, and we warranty the installation under our 90-Day Done Right Promise.
Flexible Liner Systems
Harleysville’s older masonry chimneys often have offsets or bends that rigid liners won’t navigate. Our flexible liner installations accommodate those irregular flues without dismantling the chimney structure. We see this frequently in the Pennsylvania German farmhouses near the historic district, where original construction tolerances were generous and modern inserts need a direct vent path.
Liner Replacement
Factory-built fireplaces in Harleysville’s 1980s and 1990s subdivisions were installed with manufacturer-specific liners that degrade after decades of over-firing. We replace damaged prefab liners with code-compliant stainless steel systems, matched to the appliance’s BTU rating. Generic replacements fail early. We don’t use them.
Partial Rebuild
When freeze-thaw damage has destroyed the top courses of a fieldstone chimney but the lower structure is sound, we perform partial rebuilds using matching masonry and proper crown flashing. This is common in Harleysville’s historic farmsteads where the original lime mortar has spalled after two centuries of Perkiomen Valley winters. We document the damage with camera inspection before recommending any rebuild work.

Common Chimney Liner & Rebuild Problems We See in Harleysville Homes
- Over-fired prefab fireplaces in 1960s-1990s colonials. Homeowners burn cardboard, trash, and construction scraps in factory-built units never designed for those temperatures. The flue liner cracks, the damper warps, and carbon monoxide finds its way into the living space. The fireplace looks new. It’s not safe.
- Hidden shared flues in historic farmhouses. Mid-20th-century renovations consolidated three or four original flues into one or two without proper separation. Our Level 2 camera inspection finds these before a liner installation begins.
- Generic caps on manufacturer-specific chases. A big-box store cap on a Gelco or Olympia Chimney chase lets water into the firebox, rusting the metal and corroding the liner from the outside. We replace with factory-matched units.
- Spalled lime mortar misdiagnosed as rebuild needs. Original fieldstone chimneys drop mortar crumbs that block draft and look catastrophic. Often a HeatShield liner repair restores the flue without dismantling the stack.

FAQs - Chimney Liner & Rebuild in Harleysville
Yes. Factory-built fireplaces from that era have manufacturer-specific liners that degrade with over-firing, and the damage is inside the chase where you cannot see it. We found a cracked flue tile in a Ruth Road home that had worked fine for ten years until carbon monoxide tripped the detector. Call (610) 991-8179 for a Level 2 inspection - estimates are free.
A Level 2 camera inspection reveals the difference. Spalled lime mortar dropping into the smoke chamber looks like rebuild damage but often responds to HeatShield refractory repair. Structural cracks in the exterior masonry, crown separation, or leaning stacks indicate rebuild needs. We show you the photos and explain both options before you decide.
First-degree creosote is flaky, dry soot that brushes away easily - common with dry hardwood and hot fires. Third-degree creosote is glossy, tar-like, and hardened to the flue wall; it forms when wood smolders in damp conditions or when the flue is undersized. Harleysville’s valley humidity and long heating season make third-degree buildup more likely, especially in unlined or oversized flues. Third-degree creosote cannot be swept conventionally and may require chemical treatment or liner replacement.
Yes, when the original manufacturer liner is damaged or missing, we install DuraFlex stainless steel liners sized to the appliance’s listed BTU output and clearance requirements. The liner must match the chase dimensions exactly; an oversized liner creates clearance violations and an undersized one over-fires. We pull the permit and document the installation to code.
The Perkiomen Valley’s cold air pooling and repeated freeze-thaw from November through March destroys lime mortar in historic chimneys and accelerates rust in prefab fireboxes with water intrusion. For fieldstone stacks, we see spalling that drops mortar into the flue. For newer homes, we see chase covers lifted by ice dams that let water corrode the liner from above. Both problems worsen each winter they’re ignored.
