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.
DuraFlex Chimney Cleaning & Sweep in Paterson: What to Know First
We clean and sweep DuraFlex chimney systems in Paterson for a flat rate of $229 for a standard annual sweep, with Level 2 camera inspections at $349 when your liner’s age or condition warrants a closer look. Most DuraFlex jobs run two to three hours from setup to cleanup, and every visit includes a documented photo record of what we found before we quote anything beyond the sweep itself. This page is for Paterson homeowners who own a DuraFlex liner or relining system and want someone who actually knows how those specific products behave after years of Passaic County winters. Call (862) 356-5229 and you’ll get a live person, not a voicemail.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316L ovalized liner kinks at the smoke chamber transition. We see this most often in older Paterson row houses near the Great Falls Historic District where the original flue runs slightly off-plumb. The liner gets pulled through a tight offset, kinks just above the smoke chamber, and creosote collects behind the kink where a brush can’t reach. We identify it on camera before cleaning, because running a rotary whip through a kinked section can tear the liner wall. Fix is usually a partial reline of the transition, not the whole flue.
- DuraFlex 304L alloy liner develops pinhole corrosion from coal-era residue. Paterson homes built before 1940 often had coal-burning fireplaces before conversion to gas or wood. The sulfur residue left in the original masonry reacts with stainless over decades, and 304L pinholes faster than 316L in that chemistry. We’re independent DuraFlex service providers, so our honest recommendation is sometimes a 316L replacement section rather than patching what will fail again in three years.
- DuraFlex Duraliner rigid sections separate at the joints after repeated thermal cycling. This is not a manufacturing defect; it’s physics. The liner expands and contracts every fire, and after eight to ten seasons in a Paterson chimney that runs hot in January and cold in February, the slip joints can open a quarter inch. That gap is where creosote vapor escapes into the cavity between liner and masonry. Re-seating the joint with the proper DuraFlex connector, not a generic band clamp, is a one-hour repair we do regularly.
- DuraFlex chimney caps and rain pans fail at the weld points before the liner does. The cap assembly takes the worst of Paterson’s freeze-thaw cycle. Ice forms, expands, and stresses the weld where the mesh meets the pan. Once that weld cracks, water gets between the liner and the flue tile and you won’t see it until staining appears on the ceiling below. We stock replacement DuraFlex caps and pans through our buying network, which keeps the part cost down and the repair to a single visit.
- DuraFlex smooth-wall liner builds Class III creosote faster than corrugated in short-flue Paterson chimneys. This surprises people, because smooth-wall is marketed as easier to clean. It is easier to clean, but in a short flue with a cold attic run, the smoke hangs longer before it exits, and glossy Class III creosote forms on the smooth surface in a single heavy season. We see this constantly in the two-story frames north of Route 80. The fix is a mid-season sweep rather than an annual one, which we’ll flag on your first visit if the camera shows you’re a fast-builder.
Our DuraFlex Chimney Cleaning & Sweep Process

- 1
Call and booking. You call (862) 356-5229. A live person answers, asks about your fireplace and the liner age, and we schedule a two-hour window with a named tech assigned to the job.
- 2
Camera inspection before any brush touches the flue. Corrine Halstead’s rule applies on every DuraFlex job: camera first, quote second, work third. The Level 2 camera run shows us exactly what your liner looks like inside, and we show you the footage on the spot.
- 3
Written scope and written price. If the sweep is routine, you get the $229 flat price in writing before work starts. If the camera found something, you get a written description of what it is, what it means, and a written quote for the repair. You decide, with evidence in front of you.
- 4
The sweep itself. We use brushes sized to your specific DuraFlex liner diameter, not a one-size-fits-all head. For smooth-wall liners we follow with a camera check to confirm the creosote is actually gone, not just loosened.
- 5
Photo record and written warranty. You get before-and-after camera images, a written summary of what was found and what was done, and the 365-Day Done Right Promise in writing. If something’s not right within a year, we make it right.

AfterWhat DuraFlex Chimney Cleaning & Sweep Costs in Paterson
Here’s what you can expect, written plainly:
- Standard DuraFlex sweep (annual maintenance): $229 flat, includes camera check and written photo record.
- Level 2 camera inspection with sweep: $349, needed when buying or selling, after a chimney fire, or when the liner is more than ten years old.
- Class III creosote removal: $375 to $550 depending on liner length and buildup severity. We’ll tell you before we start which end of that range you’re on, and why.
- DuraFlex liner joint re-seat or small repair: $180 to $420, parts included, quoted in writing after camera diagnosis.
- Partial DuraFlex reline: $1,200 to $3,400 depending on flue height and access. We’ll show you the camera footage first so you can see the pinhole or kink with your own eyes.
What moves the price is liner diameter, flue height, roof access difficulty, and whether you need a repair beyond the sweep. Estimates are free, always in writing, and never contingent on you saying yes. Call (862) 356-5229 for your exact number.
Why Paterson Homeowners Call Level Two Chimney Paterson for DuraFlex Work

We’re not authorized DuraFlex dealers and we won’t pretend to be. We’re an independent DuraFlex service provider, and that independence is the point. When we look at your liner, our interest is in what’s actually wrong with it, not in selling you a DuraFlex product because we carry the brand. We service HeatShield and Gelco systems too, so if your home has a mix of products from past owners, we can speak to all of it honestly. That matters in Paterson, where a house built in 1920 might have had five different liners and repairs over its life. Our techs are background-checked and uniformed, we answer the phone 24/7, and every job ends with a documented photo record you keep. The 365-Day Done Right Promise is stamped on the paperwork, not just mentioned in the pitch. If we didn’t do it right, call us and we’ll make it right.
FAQs
No. DuraFlex warranties explicitly require regular cleaning and inspection, and our sweep methods meet their stated maintenance requirements without abrasive chemicals or oversized brushes that could scratch the liner wall. We document every clean with photos, which also gives you the maintenance record warranty claims sometimes ask for. Call (862) 356-5229 if you want us to check your specific liner’s age and warranty window before your first visit.
Annually is the baseline, but many Paterson homes with short flues or heavy wood-burning should do a mid-season sweep as well. We’ll tell you on the first visit which category yours falls into, based on what the camera shows after we clean. The cost difference is real, but it’s a lot less than a chimney fire repair.
On a DuraFlex liner, we won’t sweep without a camera look first. That’s not upselling; it’s Corrine’s standing rule and it’s saved more than one Paterson customer from a torn liner or a hidden blockage that a brush would’ve made worse. The camera check is included in the sweep price, so you’re not paying extra for it.
Typical scheduling is three to seven days for non-emergency repairs, and we keep common DuraFlex parts in stock through our buying network, which shortens the wait on joint re-seats, cap replacements, and small liner sections. If you’re seeing smoke in the house or staining on the ceiling, call (862) 356-5229 and we’ll tell you over the phone whether it can wait for a normal slot or needs quicker attention.
Yes, and we’ll show you the footage that proves it either way. The camera doesn’t lie, and we don’t recommend repairs we can’t show you on screen. If it’s a sweep, the price is $229 and you get the written record. If it’s a repair, you get the written scope, the written price, and the written warranty before you decide anything. Call (862) 356-5229 and we’ll get you on the schedule.
