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.

AfterDuraFlex Chimney Cleaning & Sweep in North Bergen: What to Know First
DuraFlex chimney cleaning and sweep in North Bergen runs $189 to $349 for a standard annual cleaning, depending on the liner condition and how much creosote has built up. Most DuraFlex jobs are done the same day, and we quote a flat price before a single tool comes off the truck. That number on the phone is the number on your invoice.
This page is for North Bergen homeowners who have a DuraFlex liner or venting system and want a sweep who actually knows how that product ages, where it fails, and how to clean it without voiding the warranty. Call (848) 361-3227 and you’ll get a live person, often Wendell himself.
How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes a solid liner. But after 25 years of pulling brushes through them in North Bergen, we’ve learned exactly where they give up. Here’s what we see most often.
- DuraFlex 316L liner pitting from prolonged moisture exposure. This is the most common DuraFlex-specific issue in North Bergen homes. The 316L alloy handles heat fine, but when an unlined chimney leaks or condensation sits against the liner for years, pitting starts. Symptom: rust-colored flakes in the firebox after a rain. Fix: a Level 2 camera inspection to confirm, then either a targeted patch with a compatible DuraFlex coupler or a full liner section replacement. We never clean over active pitting without showing you the footage first.
- Flex connector snags during routine sweeping. DuraFlex flexible sections have a corrugated inner wall that catches brush bristles if the sweep doesn’t know how to rotate the rod correctly. A rushed national-chain tech can tear the inner core and never tell you. Symptom: a whistling sound when the fire burns hot, or visible spiral tears on camera. Fix: we use poly brushes sized to the liner ID and rotate rather than push-pull, then camera-verify the full length after every sweep.
- DuraFlex smooth-wall liner (DuraLiner) joint separation at the tee. The rigid smooth-wall sections are great until someone installs the tee with the wrong pitch or uses a generic aftermarket clamp. We remove the cap, scope the joint, and reseat with the proper DuraFlex band clamp. Symptom: a faint metallic rattle when wind gusts come down the flue.
- Glazed third-degree creosote on DuraFlex Pro liner surface. In North Bergen, where wood stoves run hot and often with less-than-dry wood, we see glaze form on DuraFlex Pro interiors faster than on comparable brands. The polymer coating is smooth, but it’s not immune. You can’t brush glaze off; you’ll smear it. We use a rotary head with a chain whip or an approved chemical treatment like Poultice Creosote Remover, then a followup sweep 10-14 days later. No shortcuts.
- DuraFlex aluminum liner (for gas appliances) clogged with soot and insect debris. These smaller-diameter liners clog quietly, especially in North Bergen where fall stink bugs and starlings find their way in. If you have a gas fireplace or stove on a DuraFlex aluminum liner and it’s been more than two years since a cleaning, it’s likely partially blocked. We scope it, brush it, and check vent termination clearances while we’re on the roof.
Our DuraFlex Chimney Cleaning & Sweep Process
Here’s what a DuraFlex cleaning job looks like from the first call to the final handshake.
- 1
You call, a person answers. We ask about your fireplace or stove, when it was last cleaned, and what you’ve noticed. You get an upfront price range over the phone.
- 2
We arrive, and before anything else, we lay drop cloths. Your floors stay clean, period. Then we do a visual check of the firebox, cap, and what’s visible from the roof.
- 3
Camera inspection. We run a Level 1 or Level 2 camera scope down the liner before and after cleaning. You get the footage, not just our word. This is especially important on DuraFlex because internal tears don’t show up any other way.
- 4
The sweep. Brush type matched to your liner material and diameter. For 316L flex, a properly sized poly brush with rotation. For smooth-wall rigid, a flat-wire brush. For glazed creosote, chemical treatment plus mechanical removal.
- 5
Post-sweep camera pass and report. We show you the liner is clean, note any concerns, and if a repair is needed, give you an exact written quote. You decide. No pressure.
- 6
Cleanup and the 90-Day Done Right Promise. We leave the area cleaner than we found it and you get our guarantee in writing. If something isn’t right, one call brings us back at no charge.
What DuraFlex Chimney Cleaning & Sweep Costs in North Bergen
Here’s what you’re looking at for common DuraFlex scenarios in North Bergen. These are flat, quoted-before-we-start prices.
- Standard annual sweep on a DuraFlex 316L liner: $189-$249, depending on creosote level and roof access. Most homes fall in here.
- Heavy creosote removal (second-degree or partial glaze): $269-$349. This takes longer and may need chemical treatment.
- Level 2 camera inspection (often required when buying a home or after a liner install): $149 when done with a sweep, $199 standalone. You keep the footage.
- Gas appliance vent sweep on a DuraFlex aluminum liner: $159-$219.
- Fallen liner insulation or joint repair found during sweep: We quote separately after you see the camera footage. No surprise charges.
What moves the price: how much creosote is in there, how easy the roof access is, and whether the liner was installed correctly in the first place. Call (848) 361-3227 for an exact quote. Estimates are free, and inside our service county, so is the trip.

FAQs
No, as long as the cleaning is done with tools appropriate for the liner type and diameter. We use brush sizes and materials matched to DuraFlex specs and document every job with before-and-after camera footage, which helps if you ever file a warranty claim.
Once a year, burn or no burn. Chimneys break in the off-season too, and North Bergen’s temperature swings and humidity levels can cause condensation that accelerates creosote formation and liner pitting. If you burn more than three cords a season or use softwood, you may need to sweep twice.
Yes, and we’ll show you the camera footage. We don’t recommend a liner replacement on word alone. You’ll see the pitting, tears, or separated joints yourself. If it’s safe to clean and keep using, we’ll tell you that too, and we’ll put it in writing.
Most cleanings are scheduled within the same week, and many are done the same day. We answer the phone around the clock, so if you call at 9 PM on a Sunday, you’ll talk to a live person, not a voicemail box. Call (848) 361-3227 and we’ll get you on the schedule.
We stop, show you the footage, and give you a written quote for the repair. DuraFlex couplers and sections are often on our truck. If it’s a larger job, we schedule a return visit with the specific parts needed. You get the flat price before we do anything.
