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.
Fast, Reliable Chimney Liner & Rebuild Across Fullerton
Chimney liner installation and chimney rebuilds in Fullerton typically run from $1,800 for a straightforward stainless steel liner replacement to $6,500 or more for a partial or full rebuild of a deteriorated coal-era flue. Most jobs are completed in a single visit once materials are sized, and we dispatch to Fullerton from our Philadelphia office with crews that know the Lehigh Valley bowl’s freeze-thaw patterns firsthand.
We’ve been answering calls with a live person, 24 hours a day, for over 42 years. If your Fullerton ranch or cape cod has an original chimney built for coal or oil and you’re burning wood or running a gas insert now, the flue is almost certainly the wrong size, the wrong material, or both. That’s not a guess - it’s what our camera finds on Mickley Road, on the semi-detached streets near the Fullerton Fire Company, and in the compact ranches off MacArthur Road week after week. Call us at (610) 632-1394 for a free estimate. We’ll camera-scan the flue, show you the photos, and give you a plain-English verdict before any work is booked.
Why Hearthstone Chimney Co. Is Fullerton’s Preferred Chimney Liner & Rebuild Company
Fullerton homeowners have been burned by contractors before. They remember the ones who disappeared, who upsold work that wasn’t needed, who left a mess. We don’t do any of that. Our Chimney Liner & Rebuild team works on the same principle we’ve held since 1984: the job is done right, documented with photos you can see, and backed by the 90-Day Done Right Promise in writing with no arguing.
We know Fullerton’s housing stock because we’ve worked it for decades. The post-WWII ranches and cape cods built for Lehigh Valley steel and industrial workers - compact footprints, shallow-pitched roofs, brick chimneys with no clay tile liner or with liners deteriorated by acidic oil-flue condensate. We know what a coal-stoker flue looks like when it’s been left open for sixty years. We know what happens when a previous owner stuffs a 3-inch flexible liner down a 9-by-13 flue and the gap becomes a creosote trap. That local knowledge saves Fullerton homeowners from backdrafting, from moisture damage, from chimney fires that started where no brush could reach.
Our technicians are background-checked and uniformed. Most jobs finish in one visit. Pricing is upfront - the number on the estimate is the number on the invoice. And when you call (610) 632-1394, a live person answers, every hour of every day.
Our Chimney Liner & Rebuild Services in Fullerton
Stainless Steel Liner Installation
A properly sized stainless steel liner is the right fix for most Fullerton chimneys that were built unlined or have lost their clay tile to decades of acidic flue gases. We specify and install DuraFlex and Olympia Chimney stainless liners, cut and insulated to the exact flue dimension - not a generic kit forced down a coal-era chimney. In Fullerton’s ranches and semi-detached homes, where the original flue is often rectangular and oversized for modern appliances, correct sizing matters more than the material itself. A liner too small chokes draft. A liner too large, or floating in a gap, collects creosote and condensate where you can’t see it. We measure with a camera, fabricate to fit, and document the completed flue with photos and draft readings.

Flexible Liner Systems
Flexible liners have their place in Fullerton, but only when they’re the right diameter, properly insulated, and sealed to the flue walls. The defining local hazard we find is the opposite: a gas insert with an undersized flexible liner stuffed down the middle of a wide coal-era flue, the annular gap trapping creosote and moisture invisibly from the firebox. On a cape cod off Mickley Road, our tech camera-scanned a chimney built for a coal stoker and found a 3-inch flexible liner for a gas insert crammed inside a 9-by-13 flue, with first-degree creosote and damp mortar packed in the gap. We pulled the undersized liner, wrapped and set a properly sized DuraFlex stainless liner insulated to the flue walls, rebuilt the spalled crown, and reset the flashing at the shallow ranch roofline. The camera went back down clean, draft measured correct, and the homeowner finally had a flue that matched the appliance instead of a straw in a hallway. Flexible liner done wrong is a hazard. Done right, with the correct diameter and insulation, it’s a durable fix.

Liner Replacement
Fullerton’s chimneys often need liner replacement not because the liner failed on its own, but because the wrong liner was installed years ago or because the original clay tile has spalled from acidic oil-flue condensate. We remove the failed material - whether it’s shattered clay tile, a corroded aluminum liner, or an undersized flexible tube - and replace with a system sized to your appliance and documented with before-and-after camera evidence. The Lehigh Valley’s hard freeze-thaw cycles, channeled by South Mountain and Blue Mountain, accelerate the damage once water gets behind a crown or through a flashing gap. Replacing the liner without fixing the water entry is a temporary fix. We address both.

Partial Chimney Rebuild
When the crown is spalled, the smoke chamber is eroded, or the upper courses of brick have loosened from freeze-thaw cycling, a liner alone won’t solve the problem. Partial rebuilds are common in Fullerton’s older stock where the chimney was built with the house in the 1950s or 1960s and has never had structural attention. We rebuild from the roofline up, or from the smoke chamber to the crown, using brick and mortar matched for durability and crown formulations that shed water instead of absorbing it. Every rebuild is camera-verified before and after, and covered by the 90-Day Done Right Promise.

Trusted Brands We Service in Fullerton
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For Fullerton’s demanding flue conditions, we specify DuraFlex and Olympia Chimney stainless systems, Gelco and Famco caps and crowns engineered to shed water and withstand Lehigh Valley ice, and Copperfield specialty components for custom rebuilds. These are the brands that hold up when a chimney faces twenty freeze-thaw cycles a winter and the homeowner intends to stay in the house another twenty years. We stock common diameters and fittings locally, so most Fullerton liner jobs don’t wait on shipping.
Common Chimney Liner & Rebuild Problems We See in Fullerton Homes
- Oversized coal-era flue left unlined or lined well after deterioration. Acidic oil-flue condensate has eaten clay tile to the point of spalling, so any wood stove tied to it backdrafts and loads creosote fast. The flue was built for a different fuel, a different era, and a different draft requirement.
- Third-degree creosote glazing inside a retrofit liner gap that a brush cannot touch. Common where a gas insert was dropped into an unlined flue and the annular space became a tar trap. The firebox looks clean. The camera tells a different story.
- Chimney crown and flashing failures driven by Lehigh Valley freeze-thaw and late-winter ice damming. The shallow-pitched ranch rooflines common throughout Fullerton collect snow and ice, which backs up under flashing and rots the smoke chamber from the top down while the homeowner smells nothing until the damage is structural.
- Undersized flexible liner stuffed into a flue built for coal or oil. The gap between liner and flue wall collects moisture and combustion byproducts, accelerating mortar decay and creating a hidden fire hazard that standard sweeping cannot reach.

FAQs - Chimney Liner & Rebuild in Fullerton
The flue is almost certainly too large for the wood stove, so the draft is weak and the smoke spills at startup. Coal flues in Fullerton’s post-WWII ranches were built wide and rectangular to handle the high volume of coal-stoker exhaust; a modern wood stove needs a round, properly sized liner to generate enough velocity to pull smoke upward. Without that liner, the smoke lingers, cools, and backdrafts. We camera-scan, measure the flue, and install a stainless liner matched to the stove’s outlet diameter. Call (610) 632-1394 for an exact quote - estimates are free.
If the stove heats the house full-time during winter, schedule a Level-2 inspection and sweep every year, and consider a mid-season check if you’re burning more than three cords. Fullerton’s coal-era flues, even when properly lined, can accumulate creosote faster than modern construction because the chimney mass is oversized and cools the flue gases. Primary heat source means heavier loading, shorter safe intervals, and no room for guesswork. Call (610) 632-1394 to book before burning season.
Creosote, moisture, and deteriorated mortar - often packed tight in the annular space where no brush can reach. The gap between an undersized flexible liner and the flue wall becomes a tar trap, and because the firebox looks clean, the hazard stays hidden until a camera scan reveals it. In Fullerton’s chimneys, we’ve pulled liners and found the gap filled with first-degree creosote soaked into spongy mortar, actively rotting the flue from the inside while freeze-thaw spalls it from the outside. Only a camera inspection shows what’s actually there. Call (610) 632-1394 to schedule a scan - estimates are free.
The Lehigh Valley bowl channels cold air between South Mountain and Blue Mountain, driving harder freeze-thaw cycles than flatter terrain nearby. Fullerton’s compact ranches and cape cods, with their shallow-pitched rooflines, collect heavy late-winter ice that dams at the chimney base and forces water behind flashing. Crown concrete that might last fifteen years in milder exposure spalls in eight to ten here. We rebuild crowns with formulations engineered to shed water and withstand that cycling, and we reset flashing with ice-barrier integration on low-slope roofs. Call (610) 632-1394 for an inspection - estimates are free.
A brush removes loose, first-degree creosote from a properly lined flue. It cannot touch third-degree glazed creosote, tar-packed gaps behind liners, or creosote soaked into deteriorated mortar in an unlined coal-era flue. In Fullerton, we regularly find that the visible flue looks brushable while the camera reveals glazed deposits or hidden accumulation that requires chemical treatment, mechanical removal, or liner replacement. We determine which with a Level-2 camera inspection, show you the photos, and recommend only what the evidence supports. Call (610) 632-1394 for an exact assessment - estimates are free.
