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.

Chimney liner installation and chimney rebuild in Hellertown, PA typically runs $1,800-$6,500 depending on whether you need a stainless steel liner dropped into an existing flue or a partial rebuild of a deteriorating stack.

Call (610) 991-8179 - a live person answers, 24 hours a day.
We’ve been working Hellertown’s borough grid for over 42 years, and there’s nothing generic about these chimneys. The narrow brick and clapboard rows along Main Street, the semi-detached homes climbing toward South Mountain, the pre-war blocks south of the Saucon Creek - they all share a common problem that newer Lehigh Valley suburbs simply don’t have. These houses were built for anthracite coal, converted to oil or gas decades ago, and now vent modern appliances through flues that were never designed for them. That mismatch is where cracked clay tiles, hidden voids, and dangerous draft deficiencies start. Our Chimney Liner & Rebuild team knows the difference between a chimney that needs sweeping and one that needs structural intervention because we’ve documented hundreds of them in Hellertown with cameras, photos, and plain-English verdicts.

Our Chimney Liner & Rebuild Services in Hellertown
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Hellertown chimneys with cracked or missing clay flue tiles. We install DuraFlex and Olympia Chimney stainless liners that carry a lifetime warranty and handle everything from wood-burning fireplaces to gas inserts. In Hellertown’s coal-era homes, the critical step is confirming your flue size and condition with a camera first - many of these chimneys have oversized flues that vent undersized modern appliances, causing condensation that destroys mortar joints. We measure, we camera, we show you the footage, then we quote. A typical stainless steel liner installation in Hellertown runs $2,200-$3,800.
Flexible Liner Solutions
Some of Hellertown’s older masonry has offsets, corbels, or structural shifts that make a rigid liner impossible to drop. Flexible liners from DuraFlex navigate those bends while still providing a sealed, insulated venting path. We use these in chimneys with multiple flue bends or in partial rebuilds where we’re preserving original masonry. Flexible liner installation in Hellertown typically costs $2,500-$4,200 depending on length and access.
Liner Replacement
When your existing liner has failed - cracked clay tiles, spalled surfaces, or gaps between joints - replacement isn’t optional. Combustible gases and creosote can leak into wall cavities. In Hellertown’s row homes, where chimneys often sit on shared walls, that risk extends to neighboring units. We remove the damaged liner, inspect the surrounding masonry with a camera, and install a new system sized precisely for your appliance. Liner replacement in Hellertown generally runs $1,800-$3,500. We also handle HeatShield cerfractory flue sealant applications for select clay-tile repairs where full replacement isn’t needed.
Partial Chimney Rebuild
Sometimes the liner isn’t the only problem. In Hellertown’s pre-WWII homes, we’ve rebuilt smoke chambers, repointed mortar joints destroyed by freeze-thaw cycles, and replaced chimney crowns that were shedding water into the stack instead of away from it. A partial rebuild addresses the failing components without the cost of tearing down the entire chimney. Typical partial rebuilds in Hellertown range from $3,500-$6,500. We use professional-grade materials from Gelco and Copperfield, matched to your existing masonry for a repair that lasts.

Common Chimney Liner & Rebuild Problems We See in Hellertown Homes
- Hidden furnace-flue voids behind masonry plugs. On Hellertown’s older blocks along Main Street and the surrounding pre-war grid, our technicians frequently find that the same chimney once served both a coal furnace flue and a separate fireplace flue. A prior owner capped or partially blocked the furnace flue without proper documentation, leaving hidden voids that trap moisture, crumble liner sections, and only become visible during a thorough sweep and camera inspection.
- Valley downdraft off South Mountain. Hellertown sits in the Saucon Creek valley with South Mountain rising to the south and southwest. The topography funnels prevailing winds in ways that create intermittent downdraft on chimneys oriented toward the ridgeline. Homeowners call us thinking they have a “draft problem,” but the real issue is often a cracked liner or missing flue tiles letting smoke leak into the house under pressure.
- Oversized flues accelerating condensation damage. The overwhelming majority of Hellertown’s housing stock dates from roughly 1900-1945, built with multi-flue chimneys sized for coal stoves and coal furnaces. Those same flues now vent gas or oil appliances that produce far less heat and exhaust. The undersized output can’t keep the flue warm, so condensation forms, mortar joints fail, and liner degrades faster than in newer construction with properly sized flues.
- Freeze-thaw destruction of clay tiles and mortar. Hellertown’s hard Pennsylvania winters bring regular freeze-thaw cycles that expand and crack aging mortar joints and clay flue tiles. The damage is worse on chimneys with existing moisture intrusion - often from failed crowns or the hidden voids described above - and it accelerates every season until the liner is replaced or the chimney is rebuilt.

FAQs - Chimney Liner & Rebuild in Hellertown
Yes, almost certainly. In Hellertown’s 1920s row homes, the original clay flue tiles are now a century old and were sized for coal appliances that produced far more heat than your current system. A chimney that looks sound from the curb often has cracked tiles, failed mortar joints, or hidden voids where a prior owner capped a furnace flue. We run a Level-2 camera inspection and show you the footage before recommending any work. Call (610) 991-8179 for a free estimate - estimates are free.
It can be a serious problem, and it’s one we find constantly in Hellertown’s pre-war housing stock. On a semi-detached brick row home off Main Street near the Saucon Creek valley, our tech swept what looked like a single flue and found a hidden furnace-flue void a prior owner had blocked off with a masonry plug - moisture had been collecting there for years, spalling the clay tiles and feeding third-degree creosote on the fireplace side. We ran a camera the homeowner watched in real time, showed the cracked clay joints and the capped void, then installed a DuraFlex stainless liner in the fireplace flue, rebuilt the smoke chamber, and reset the chimney crown to shed water off the stack. The furnace flue was properly sealed with documented venting, ending the cycle of freeze-thaw damage that kept eating the mortar joints each winter. If you suspect a prior modification, call us for a camera inspection.
Downdraft from South Mountain’s ridgeline is often the culprit, but the underlying cause is usually a compromised liner. Hellertown’s valley topography funnels winds that push smoke back through chimneys oriented toward the slope. A cracked clay liner or missing flue tiles let that pressure force smoke into your living space instead of up the stack. A basic sweep removes creosote but doesn’t fix liner failure. We diagnose with a camera and pressure test, then repair or replace the liner so the chimney drafts properly regardless of wind direction. Call (610) 991-8179 - we’ll show you exactly what’s happening inside your flue.
It does. Hellertown’s hard continental winters produce repeated freeze-thaw cycles that expand water trapped in cracked mortar and spalled clay tiles. Each cycle widens the damage. The effect is worse in chimneys with moisture intrusion from failed crowns or the hidden voids common in converted coal flues. A sound liner and properly rebuilt crown stop water from entering in the first place. That’s why we inspect both components together and document everything with photos you can see. Call (610) 991-8179 for a free estimate - estimates are free.
You see the evidence yourself. We don’t recommend liners, rebuilds, or any repair without camera footage you watch in real time and photos you keep. In Hellertown’s older homes, where hidden furnace-flue voids and century-old clay tiles are routine, the camera separates real problems from invented ones. Our 90-Day Done Right Promise - in writing, no arguing - means if we install a liner and something isn’t right, we come back. No paperwork games. We’ve been in business since 1984 because we don’t burn customers. Call (610) 991-8179 and we’ll show you exactly what your chimney contains before you spend a dollar.
