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.
Why Paterson Homeowners Choose DuraFlex Chimney Cleaning
Duraflex repair in Paterson typically runs between $189 and $320 for a standard 1-2 story single-flue sweep, and Level Two Chimney Paterson includes a camera inspection with every visit. We’re an independent DuraFlex service provider, which means we can tell you plainly when a liner just needs a rotary-whip cleaning or when it’s corroded enough that patching it would be throwing money away. That honesty matters in Paterson, where century-old Silk City row houses and tenement stacks put liner systems through conditions most suburban chimneys never see.

Our DuraFlex work is built on the same standard we’ve applied to every one of the 38,000-plus chimneys we’ve inspected since 2009: a written price before anything starts, a camera record of what we found, and a 365-Day Done Right Promise behind every job. Corrine Halstead, the owner of Level Two Chimney Paterson, has been cleaning and lining chimneys for eighteen years, with a long stretch of that work in the older row houses near the Great Falls Historic District where original masonry and difficult flue conditions are the norm. Call (862) 356-5229 and a live person answers, 24/7. We won’t book a cleaning on a DuraFlex chimney we haven’t first put a camera down.
Why Trust Level Two Chimney Paterson for Your DuraFlex Chimney Cleaning?
DuraFlex 316L flexible liners are common in Paterson because they’re adaptable to the tight offsets and multi-flue stacks in pre-1940 brick buildings. That same flexibility is also why they fail in predictable ways: kinked sections from drops without pulling cones, pinhole corrosion where acidic creosote sits against the corrugations, and loose top plate connections that let rain run down the liner exterior. Our techs know which signs mean a simple clean and which mean a section replacement. We’ve worked on hundreds of DuraFlex installations in Paterson’s older masonry chimneys, most of them layered over coal-era flues that were never designed for gas or oil exhaust.
When we order replacement parts for DuraFlex systems, we spec OEM tees, caps, and clamps rather than generic flex, because knockoff corrugation pitch doesn’t seat properly and fails early. We’re not authorized by DuraFlex, and we don’t pretend to be. What we bring is eighteen years of hands-on experience with the product line in this city’s specific housing stock, documented in photos and written up before we quote a dollar. Clause 1 of the Haven Standard says it outright: a written price, written scope, and written warranty are delivered before anyone starts, not after a tech is already in your living room.
Corrine’s rule on every DuraFlex job in Paterson is the same one she’s held since her days coming up through the trades at Bronx Community College: camera first, quote second, work third, in that order, every time. If we can’t show you the problem on the screen, we don’t expect you to pay for the fix.
Common DuraFlex Chimney Cleaning Problems We Fix in Paterson

DuraFlex liners don’t fail randomly. They fail in patterns we’ve mapped across hundreds of Paterson flues. Here are the five we see most often:
- Pinhole corrosion in 316L stainless liners. This shows up most on exterior chimneys in Paterson’s uninsulated brick stacks, where the liner has no thermal barrier and acidic creosote condensate pools against the corrugation valleys. By the time you see rust streaks outside the liner, the pinholes have usually already opened. We find them with the camera, not guesswork.
- Crushed or kinked flex sections. A previous installer forces the liner through an offset without a pulling cone, and the corrugations collapse at the bend. Draft drops, creosote builds up behind the kink, and the fireplace starts smoking back into the room. We replace the section with new DuraFlex and pull it properly this time.
- Loose top plate and rain cap connections. Water runs down the outside of the liner, between the flex and the old clay tiles, then accelerates corrosion from the outside in. We see this constantly in Paterson, where the damp river valley air and freeze-thaw cycles on Garret Mountain slopes put extra stress on cap assemblies.
- Heavy creosote packing in flex liner corrugations. Third-degree glazed creosote builds faster in flexible liners than rigid pipe because the corrugations give deposits a place to grip. We run rotary whips designed for flex systems and pull out deposits that homeowners assume mean the fireplace is dead. Often it just needs a proper mechanical clean.
- Delaminated seams in older aluminum liners. If the liner is the original AL 29-4C or an early aluminum flex, high flue temperatures from a chimney fire can separate the seam folds. Once that happens, the liner won’t hold draft and exhaust leaks into the chimney cavity. There’s no cleaning fix for this; the section comes out.
All of these get documented with camera footage before we quote anything. You see what we see.
Before
AfterDuraFlex Parts & Our Repair-vs-Replace Approach
The honest answer for most Paterson homeowners is that a DuraFlex liner that’s cleaned regularly and wasn’t badly installed will last years without replacement. The dishonest answer, the one you’ll hear from operations that quote a new liner at the first sign of creosote, is that everything needs replacing. We don’t work that way.
For cleaning and maintenance we use OEM DuraFlex components: tees, caps, clamps, and top plates. The reason is the corrugation pitch. Aftermarket flex often has a slightly different corrugation depth, which means clamps slip, connections wobble, and you’re back on a ladder in a year. Genuine DuraFlex parts seat correctly because they were formed to the same dies as the liner you already have. We stock common DuraFlex tees and caps locally, so most top-end repairs don’t wait on shipping.
The repair-versus-replace call happens only after a camera scan. If a section is pinhole-corroded or crushed, we replace that section with new DuraFlex, not a foil tape patch or expanding foam, which fails quickly and looks exactly like it sounds. If the liner is simply dirty, we clean it and tell you it doesn’t need replacing. Clause 4 of the Haven Standard requires a photo record on every job, so you’ll have before and after images to verify the condition. Call (862) 356-5229 for an honest assessment and a written price.
Our DuraFlex Service Process - Step by Step

- 1
Camera-first diagnosis. We run a Level 2 camera scan down the full length of your DuraFlex liner and record the footage. You see the creosote buildup, the pinholes, the kinked section, or the clean liner, whatever we find. No work starts until you’ve seen the same screen we did.
- 2
Written scope and written price. We tell you exactly what needs cleaning, what needs replacing, which parts we’ll use, and what it costs in writing. This is Haven Standard Clause 1, and we’ve never skipped it on a single Paterson job.
- 3
Cleaning or section replacement. For creosote removal we use rotary whips sized for flex liner corrugations. For damaged sections we cut out the bad run and couple in new DuraFlex with OEM connectors, not tape or foam.
- 4
Draft and leak testing. After any DuraFlex service we test draft and check the top plate and rain cap seals. In Paterson’s wind-deflected western slopes near Hillcrest and Totowa, a loose cap connection causes downdrafts we can measure before you light your first fire of the season.
- 5
Written warranty and photo record. You get the camera archive, the written scope, and the written warranty on every job. The 365-Day Done Right Promise applies to all of it: if it’s not done right, we make it right.
DuraFlex Products We Service & Install in Paterson
Our Paterson crews service and install the full DuraFlex residential liner line. That includes the DuraFlex 316L flexible chimney liner, the AL 29-4C stainless liner for higher temperature oil and gas applications, the Pro 316TI rigid/flex hybrid for straight runs where rigid pipe improves draft, and the DL (Double-Lok) liner for installations where a smoother interior wall reduces creosote adhesion. We keep common diameters in stock for fast turnaround on Paterson row house jobs, where flue sizes from the coal era often run non-standard and need field-sizing. If your liner size isn’t on the truck, we order it and schedule the install when it lands.
We Also Service These Brands

DuraFlex isn’t the only system we work on in Paterson-we also offer Fair Lawn Duraflex service. We also service and install HeatShield cerfractory flue sealant systems and Gelco liners, plus a range of other manufacturer products. That multi-brand experience means we’re not tied to selling you one product when another fits your chimney better. If your flue configuration calls for something other than DuraFlex, we’ll tell you and quote that instead.
FAQs - DuraFlex Chimney Cleaning Service in Paterson
Yes, and that’s standard practice. We clean DuraFlex liners in place using rotary whips specifically sized for the flex corrugations. The liner stays exactly where it is. What we don’t do is attempt a clean without first running a camera scan to make sure the liner can tolerate mechanical cleaning. A liner with pinhole corrosion or delaminated seams could tear under the whip, so the camera always runs first. Call (862) 356-5229 to schedule a Chimney Cleaning & Sweep with inspection included.
Rust streaks usually mean a failed top plate or rain cap seal is letting water run down the exterior of the liner and pool against the old flue tiles. The liner itself may still be intact, but the standing moisture will eventually pinhole the 316L steel, especially on Paterson’s exterior chimney walls where there’s no insulation between the flex and the brick. We find and fix the leak source, then camera the liner to confirm whether corrosion has already started. Every DuraFlex inspection includes the photo record so you can see the rust origin point.
No, and anyone who says otherwise isn’t actually seeing the liner. A proper camera inspection of a DuraFlex system requires removing the rain cap and top plate to access the flue from above. We take the cap off, run the camera down the full liner length, and document everything on video. That’s the only way to catch pinholes in the upper third of the liner and hairline cracks in the cap connection that are invisible from below.
It depends entirely on what the camera shows. A 15-year-old DuraFlex liner that was installed correctly and cleaned regularly may be in serviceable condition. A 15-year-old liner that was kinked during installation or has been burning green wood may need section replacement. We’ve cleaned 20-year-old liners that were fine and replaced 6-year-old liners that were destroyed by chimney fires. The liner’s age matters less than its history and current condition. Get a camera scan and a written recommendation before you spend thousands on a liner you may not need.
Sometimes, but not with tape or sealant. A small tear or pinhole near a connection point can often be addressed by cutting out the damaged section and coupling in new DuraFlex with an OEM connector. If the tear is in the middle of a long run, section replacement is straightforward. If the corrosion is widespread, a full reline is the safer call. We’ll show you the camera footage and quote only the repair you actually need. Call (862) 356-5229 for an exact quote, estimates are free.
DuraFlex cleaning in Paterson runs $189 to $320 for a typical single-flue chimney, with the price set in writing before we start. Multi-flue row houses and tenement stacks, which are common in Paterson’s Silk City building stock, run higher because of the additional flues and access complexity. Camera inspection and photo documentation are included in the price, not billed as add-ons. Call (862) 356-5229 for a written quote on your specific chimney, free of charge.
