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.

We’re an independent service company - not authorized or endorsed by DuraFlex - that handles these stainless and aluminum liner systems in Collingswood’s century-old masonry flues every week. Call (856) 741-9572 for a written estimate before any work starts.
Why Collingswood Residents Choose Us for DuraFlex Service
Corrine Halstead grew up in Queens and learned this trade through Queensborough Community College before working chimneys up and down the East Coast. She and our crew have been in Camden County long enough to read the crack patterns in Collingswood’s clay flue tiles like a map - especially the offset failures and liner ovalization that show up in row-home chimneys built before 1940. The camera shows it. The report names it. The price is written before we ask for anything.
We stock genuine DuraFlex connector components and termination caps because off-brand equivalents vary in dimension and alloy rating enough to cause fit problems in old masonry flues. Every visit includes an NFPA 211 Level 2 camera-scan inspection and a documented photo record under Haven Standard Clause 4 - a practice we started in 2009, years before insurers or regulators asked for it. Our technicians are background-checked, uniformed, and named on your appointment; you get a text when they’re on the way. The 365-Day Done Right Promise applies to every job, and we offer a Free Second Opinion on any competitor’s written estimate.
Common DuraFlex Chimney Cleaning Problems We Solve in Collingswood
- Aluminum DuraFlex liners exposed to wood or oil flue gas. Some Collingswood homes started with gas conversions and later switched to wood inserts or oil appliances. The DuraFlex AL 316L or AL 304L aluminum liner has no business seeing 1000°F flue gas. It warps, cracks, and can collapse. We find this most often on the twin blocks off Irvin Avenue where a 1990s gas conversion got reversed.
- Corrosion pitting on stainless DuraFlex from chronic condensation. Collingswood’s coal-to-gas conversion wave left flues physically too big for the appliances now venting into them. Undersized draft means acidic flue gas and condensation sit against the liner wall far longer than in a properly sized post-1940 chimney. The Cooper River humidity doesn’t help. We measure draft and liner condition together; a sweep alone won’t fix a sizing mismatch.
- Torn or kinked liner sections from improper sweeping technique. Century-old multi-flue chases in Collingswood’s row homes often have slightly ovalized liners at the offset. The wrong brush or excessive force tears the DuraFlex wall. We use rotary systems sized to the liner diameter and inspect with the camera before and after.
- Disconnected or improperly terminated DuraFlex at the top plate or appliance collar. This is a frequent source of CO spillage in Collingswood’s shared party-wall stacks along Collings Avenue and Park Avenue, where the run to the cap is long and awkward. We document the termination explicitly in every report because a breach in one unit can affect the neighbor.
- Missing or failed top plates with crown gaps. South Jersey’s freeze-thaw cycling drives spalling in aging mortar. A DuraFlex liner with no proper top plate or a three-inch crown gap pulls outdoor air and moisture down the flue, destroying draft and accelerating liner corrosion. We inspect crowns and top plates as standard, not as an upsell.

AfterDuraFlex Service in Collingswood: What Local Conditions Mean for Your Equipment
Collingswood’s roughly 1.5-square-mile grid is packed with Victorian and Edwardian-era row homes and semi-detached twins built between 1890 and 1935. Most had their original oversized coal-furnace flues converted to gas or oil without relining, leaving chronically undersized draft relative to the flue volume. That volume mismatch accelerates moisture intrusion and creosote layering in ways that would not be the pattern in a postwar suburb like neighboring Cherry Hill. Every chimney cleaning here should double as a liner-sizing and draft evaluation, not just a sweep.
On a Park Avenue row home, a homeowner called because the DuraFlex 6″ stainless liner that had been dropped into an original coal-furnace flue could not hold draft for the wood insert. We found the liner had been terminated with no top plate and a three-inch gap at the crown. We pulled the liner, found a kinked section at the offset, replaced that run, set a proper DuraFlex top plate and sealed the crown, and the insert drafted clean the same afternoon. That job is why we do not quote sweeps over the phone for Collingswood’s pre-1940 housing stock - we need the camera down the flue first, and why we recommend our Chimney Repair in Collingswood when damage is found.
DuraFlex Models & Products We Service in Collingswood
We work on the full DuraFlex line: the Stainless Steel Relining Kit in 6″ and 7″ diameters, the AL 316L and AL 304L aluminum liner kits for gas-only applications, DuraFlex Insulated Liner Kits, and DuraFlex Vent Kits with termination caps. Our Collingswood-area truck stocks genuine DuraFlex top plates, connector sleeves, and termination hardware - not aftermarket copies - because the fit tolerances in century-old masonry flues are unforgiving. If your DuraFlex liner is sound, we clean and reuse it. If it is pitted, kinked, or undersized for the appliance, we say so plainly and write the replacement scope and price before any work begins. DuraFlex sales & service details are available for full relining projects.

FAQs - DuraFlex Chimney Cleaning in Collingswood
My Collingswood row home has an original clay tile liner and a DuraFlex stainless liner inside it - do I need both inspected?
Yes. The clay tile liner is the structural flue; the DuraFlex is the functional vent path. We camera both because tile cracks at the offset can ovalize or damage the DuraFlex, and gaps between the two can create dangerous thermal or clearance issues. Call (856) 741-9572 to schedule; estimates are free.
Can you clean a DuraFlex liner without damaging it?
Yes, if the liner is in serviceable condition and the sweep uses the right equipment. We use rotary systems sized to the liner diameter and inspect with the camera before and after. If the liner is already kinked, torn, or corroded, we document that and recommend replacement rather than risk further damage with a sweep that will not hold.
Why does my chimney smell worse than my neighbor’s on the same block?
Probably draft. Collingswood’s oversized coal flues with undersized DuraFlex liners create negative pressure issues that pull odors down instead of exhausting them. The shared party-wall construction means your flue may interact with your neighbor’s stack dynamics. We measure draft and liner termination as part of every inspection.
Is a DuraFlex aluminum liner safe for my gas fireplace in Collingswood?
The DuraFlex AL 316L or AL 304L is rated for gas-only applications. If your fireplace is strictly gas and the liner was properly sized and terminated, yes. If you have switched or plan to switch to wood or oil, the aluminum must be replaced with stainless. We verify appliance type and liner rating during inspection.
Do Collingswood’s freeze-thaw winters hurt the DuraFlex cap and top plate?
The DuraFlex components themselves handle freeze-thaw fine. The problem is the masonry they mount to. Spalling crowns and eroded mortar joints let water reach the top plate hardware, causing rust, loosening, and eventual separation. We inspect and document crown condition on every visit. Call (856) 741-9572 for a camera inspection before next winter.
