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 Collingswood
Stainless Steel Liner Installation
Collingswood’s unlined coal-era flues are almost always oversized for modern gas inserts and oil burners. A properly sized stainless liner - we typically spec DuraFlex or Olympia Chimney grade - brings the flue back to code, stops acidic condensation from eating mortar, and corrects the weak draft that leaves smoke lingering in the firebox. Most Collingswood twins need this. We measure on-site, show you the camera footage, and quote before ordering.

Flexible Liner Systems
Tight attic spaces and offset flues in Collingswood’s older housing stock often rule out rigid pipe. Flexible liners navigate the jogged chimney throats common in 1910s and 1920s construction without dismantling walls. Our Chimney Liner & Rebuild team carries multiple diameters on the truck for same-day fitment when the job allows.

Liner Replacement & Partial Liner Repair
Not every cracked terracotta tile means a full tear-out. HeatShield cerfractory foam lets us resurface damaged flue sections in place, saving Collingswood homeowners the cost of a complete stainless system when the existing structure is sound. We only recommend this after camera inspection - you’ll see the damage yourself before we quote.

Partial Chimney Rebuild
South Jersey’s freeze-thaw cycles destroy soft lime mortar in Collingswood’s century-old stacks. When spalling brick, missing mortar joints, or a failed crown threaten the flue’s structural integrity, we rebuild from the roofline up - matching existing brick where possible, pouring a new concrete crown with proper drip edges and overhang. On twin-home stacks, we coordinate with both owners before touching the party wall.

Common Chimney Liner & Rebuild Problems We See in Collingswood Homes
- Oversized coal-era flues condensing moisture into cracked terracotta. Every block in Collingswood repeats this pattern: the original flue was built for a coal furnace, now a gas insert vents into a space too large to stay hot. Exhaust cools, condenses, and spalls the clay tile from the inside out. Camera inspection shows it clearly.
- Acidic flue gases eating soft lime mortar from the inside. Without a stainless liner, modern appliance exhaust attacks the century-old mortar joints. The damage shows up first as loose bricks at the crown, then as gaps in the flashing, then as interior wall staining. We catch it before the stack leans.
- Neighbor’s damaged flue re-contaminating a freshly lined stack. On Collingswood’s twin-home blocks, one missing cap or collapsed tile lets creosote moisture migrate across the party wall into your flue. Freeze-thaw from December through March re-damages your liner within one heating season. We knock on both doors before we quote.
- Efflorescence and spalling on lower courses from Cooper River basin moisture. Collingswood’s proximity to the flood plain means higher ambient humidity year-round, accelerating brick face damage and mortar decay on chimney bases visible from the sidewalk.

FAQs - Chimney Liner & Rebuild in Collingswood
We can line your flue and repair your portion of the stack, but we need to inspect the entire masonry column and usually coordinate with your neighbor. Because both flues share one chimney structure, a missing cap or open mortar joint on their side lets moisture and gases migrate into your newly lined flue. We knock on both doors before quoting, and we’ll show both owners the camera footage so everyone understands what the stack needs. Call (856) 543-2929 to schedule - estimates are free.
Your flue was sized for a coal furnace or coal-fired kitchen range, not a modern gas insert. Coal burned hot and fast; gas burns cooler and produces more moisture. The oversized flue stays too cool, exhaust slows, and you get weak draft plus condensation that cracks terracotta and stains walls. A properly sized stainless liner fixes the draft and protects the mortar. We’ll measure and show you the camera evidence before recommending anything.
No. We recommend a liner only when camera inspection shows deteriorated terracotta, glazed creosote, or flue gases damaging mortar - and we show you the photos before we say a word about replacement. Age alone is not a reason to spend money. If your clay tile is sound and your appliance vents properly, we’ll tell you so. The 90-Day Done Right Promise only matters if we actually do the work.
It’s both freeze-thaw and acidic flue condensation working together. South Jersey’s winter temperature swings crack soft lime mortar joints, then spring rain and summer humidity carry dissolved salts to the brick face as efflorescence. Without a liner, acidic exhaust accelerates the damage from inside. Collingswood’s proximity to Cooper River means higher ambient moisture than towns on higher ground, so the cycle moves faster here. Camera inspection tells us whether the damage is cosmetic or structural.
Yes - the standard requires annual inspection for all solid-fuel chimneys, and the CSIA recommends annual inspection for gas and oil systems as well. But “inspection” does not mean “sales pitch.” Our Level-2 camera inspection documents condition with photos you can see. If your flue is sound and your liner is intact, the report says so. In Collingswood’s housing stock, we often find problems the homeowner never suspected, but we also clear plenty of chimneys with a clean bill of health. Call (856) 543-2929 to book - the inspection itself is straightforward, and you’ll know exactly where you stand.
