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.

Our Chimney Liner & Rebuild Services in Hellertown
Stainless Steel Liner Installation
Stainless steel liners are our go-to solution for Hellertown’s pre-war chimneys - especially the shared stacks common in borough twins and row homes along Easton Road and Main Street. These liners create a sealed, properly sized flue inside deteriorating clay tile or bare masonry, which matters enormously when two households depend on the same brick stack. A typical stainless steel liner installation in Hellertown runs $2,200-$3,800 for a straightforward single-flue job, and $3,200-$5,500 for shared-stack situations requiring separate liner drops. We source our stainless components from DuraFlex and Olympia Chimney - professional-grade materials, no builder-grade substitutes.
Flexible Liner Installation
Flexible liners solve the access problem in Hellertown’s tighter properties, where offset flues or structural obstacles make rigid stainless steel impractical. In some of the borough’s narrower twins, the flue path shifts between floors or angles around a structural member installed during a century of modifications. Flexible liners from trusted manufacturers navigate these offsets without breaking the flue’s integrity. We see this most often in the 1910s-1930s worker housing south of Main Street, where original construction met decades of improvised repairs.
Liner Replacement
Liner replacement in Hellertown usually means pulling out failed clay tile that was sized for coal and never updated for oil, gas, or modern wood-burning appliances. The original liners in these homes are too large for today’s equipment, creating poor draft, condensation damage, and accelerated deterioration. We were called to a 1920s brick twin on Easton Road where one unit’s gas furnace was backdrafting into the neighbor’s living room. Our crew dropped a camera and found the original clay-tile flue liner was spalled and misaligned for the furnace’s modern draft, while the shared stack also served the neighbor’s water heater. We installed a stainless steel liner with proper cap and crown repair, restoring separate venting and eliminating the cross-contamination. Liner replacement in Hellertown typically runs $1,800-$3,500.
Partial Chimney Rebuild
Partial rebuilds address the structural damage that Saucon Valley’s freeze-thaw cycling inflicts on Hellertown’s aging brick stacks. When spalling brick, deteriorated mortar joints, or a failed crown compromise the chimney above the roofline but the lower structure remains sound, we rebuild from the roof up. This is common on properties where water has penetrated the crown and saturated the brick through multiple freeze-thaw seasons. In Hellertown’s dense housing, roof access is tight and scaffolding sometimes requires coordinating with adjacent property owners - something our crews handle regularly. Partial rebuilds in the borough typically range $3,500-$6,500.

Common Chimney Liner & Rebuild Problems We See in Hellertown Homes
- Shared masonry stacks allow cross-contamination between units. Many Hellertown row homes and twins share a single chimney stack between two units, so a cracked or missing flue liner on one side can allow flue gases and creosote odors to contaminate the neighboring unit’s space through the shared stack. This is a liability and health concern that simply doesn’t exist in detached suburban homes.
- Original clay-tile liners are oversized for modern appliances. These flues were built for coal-burning furnaces and are now too large for efficient oil or gas equipment. The result is poor draft, excessive condensation, and rapid deterioration of whatever liner material remains - a pattern we see repeatedly in Hellertown’s 1910s-1950s housing stock.
- Saucon Valley freeze-thaw cycling destroys mortar and crowns. Hellertown sits in a valley flanked by South Mountain and surrounding ridges, which accelerates cold-air pooling and creates aggressive freeze-thaw conditions. Brick spalls, mortar crumbles, and crowns crack - often affecting both units served by a shared stack.
- Wood-burning stove retrofits overload aging flues. Many Hellertown homeowners supplement with wood-burning stoves through the long Lehigh Valley heating season, but install them into chimneys never designed for the concentrated heat and creosote production. The combination of an unlined or improperly sized flue with heavy creosote buildup is a genuine fire hazard.

FAQs - Chimney Liner & Rebuild in Hellertown
Yes - each unit venting into a shared stack needs its own properly sized, sealed flue liner. Without separate liners, exhaust gases, carbon monoxide, and creosote odors can migrate between units through cracks and gaps in the shared masonry. We coordinate with both households when possible, document the shared stack with camera inspection photos both parties can review, and install independent liners with proper termination. Call (610) 756-1504 to schedule a joint or individual inspection - estimates are free.
The only reliable way is a Level-2 camera inspection that lets you see the flue’s interior condition yourself. Original clay tile in Hellertown’s coal-era chimneys is frequently spalled, cracked, or misaligned for modern gas equipment’s lower draft temperatures, and the oversized flue diameter causes condensation that accelerates deterioration. We drop a camera, show you the footage, and give you a plain-English verdict on whether the liner can be repaired or needs replacement. Call (610) 756-1504 to book - estimates are free.
A properly executed partial or full rebuild with correct crown design and professional-grade materials eliminates the water infiltration that drives freeze-thaw damage. We rebuild with sloped crowns, proper overhang, and quality flashing to shed Saucon Valley rain and snow before it saturates the masonry. The key is addressing not just the visible spalling but the water path that caused it. Call (610) 756-1504 for an inspection and exact quote - estimates are free.
Heavy creosote buildup in a shared stack creates fire and air-quality risks for both households, because chimney fires can damage the shared masonry and cracks in one liner can allow gases to enter the other unit’s flue path. In Hellertown’s attached housing, one neighbor’s neglected maintenance becomes the other neighbor’s exposure. We recommend coordinated annual inspections and cleanings for shared-stack properties, and we can document each unit’s condition separately for your records. Call (610) 756-1504 - estimates are free.
We use both, depending on the flue’s condition and the appliance being vented. HeatShield cerfractory resurfacing works well for clay tile flues with moderate deterioration that remain structurally sound, while stainless steel liners are our standard for severely damaged flues, improperly sized coal-era chimneys, and shared-stack situations requiring separate venting paths. Our inspection determines which solution fits your specific chimney - we don’t guess, and we don’t sell you more than you need. Call (610) 756-1504 for a camera inspection and exact recommendation - estimates are free.
