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.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes a solid range of chimney liners and venting components, but like any metal system exposed to Paterson’s freeze-thaw cycles and high-moisture winters, certain failure patterns show up repeatedly. Here’s what we find on DuraFlex systems in homes across Paterson, from the historic row houses near the Great Falls to newer construction on the east side:
- DuraFlex 316Ti liner pitting at the tee connection. The 316Ti alloy handles flue gas well, but at the tee where the liner meets the appliance, condensation collects and sits. In Paterson’s damp winters, that condensate is acidic and slowly eats at the base of the tee. Symptom: rust staining on the cleanout door or a faint metallic odor near the fireplace. Our fix: we camera-scan the full run, measure wall thickness at the tee, and replace the section with the same-gauge 316Ti - never an off-spec alloy - so the repair matches the original material.
- DuraFlex DRS series rigid-to-flex transition leaks. On homes where rigid DuraFlex sections run through the smoke chamber and flex runs up the flue, the transition collar is a known weak point. Heat expansion and contraction work the connection loose over three to five years. Symptom: you’ll see creosote staining on the smoke shelf or smell smoke after the fire is lit. Our fix: inspect the collar, verify the connection hardware, and re-secure with the correct high-temp sealant and stainless band. If the collar itself is deformed, we replace it.
- DuraFlex 304 series kinking in offset installations. Homes with angled or offset flues - common in older Paterson chimneys - put flex liners at risk of kinking during installation if the liner isn’t pulled through carefully. A kink reduces the cross-sectional area and creates a creosote trap. Symptom: the fireplace drafts fine for ten minutes, then smoke starts spilling into the room. Our fix: camera-scan to find the kink, then re-pull or replace that section. We do not patch kinks - patched liners fail anyway.
- DuraFlex AeroVent termination cap corrosion. The cap is the first component to go in Paterson because it sits exposed to rain, snow, and the constant humidity off the Passaic River. The stainless is good, but the screen mesh corrodes first and can restrict airflow. Symptom: reduced draft, especially on windy days, or debris accumulating on the cap. Our fix: replace the cap with a DuraFlex or equivalent stainless mesh cap - under $100 for the part typically - and re-check draft.
- Improperly sized DuraFlex liner installed by a previous contractor. More common than DuraFlex material defects is liner sizing mistakes. A liner that’s too narrow for the appliance causes overheating of the flue wall; too wide and you get poor draft and backdraft. We measure the liner ID with a caliper and verify it against the appliance BTU rating. When it’s wrong, we quote a correct liner replacement and document everything with camera footage so you can see the problem yourself.
Corrine Halstead has been working on DuraFlex systems for most of her eighteen years in the trade. She’ll tell you the same thing she tells every Paterson homeowner: the liner is only as good as the installation. Camera first, quote second, work third - in that order, every time.
Our DuraFlex Fireplace Services Process

When you call (862) 356-5229, here’s exactly what happens on a DuraFlex fireplace service call in Paterson:
- 1
Call and schedule. A live person answers 24/7. We book your visit and assign a named, background-checked technician. You get a text when we’re on the way.
- 2
Camera-scan inspection (NFPA 211 Level 2). We run a camera down the flue before we touch anything. You watch the footage with us. Every DuraFlex job starts this way because you can’t diagnose what you can’t see.
- 3
Written diagnosis and price. We hand you a written scope of work and a line-item price. No verbal estimates, no “rough numbers.” You approve it in writing before any work starts - that’s Haven Standard Clause 1.
- 4
Parts decision: OEM DuraFlex versus quality aftermarket. We’re transparent about when OEM is required for warranty reasons and when an aftermarket equivalent (like HeatShield or Gelco products) performs identically at a better price. You choose before we order anything.
- 5
Repair or replacement. We complete the work, then test the system: draft measurement, smoke test, and a final camera pass to document the result.
- 6
Documented photo record and written warranty. You leave with photos, camera stills, draft readings, the written scope, and a written warranty. If it’s not done right, we make it right - that’s the 365-Day Done Right Promise on every single job.

AfterWhat DuraFlex Fireplace Services Cost in Paterson
Paterson pricing depends on what the camera shows, but here are the numbers we actually quote most often:
- Diagnostic camera-scan inspection: $89-$149 (credited toward any repair we do)
- DuraFlex tee section replacement (316Ti): $280-$520
- Termination cap replacement: $95-$210 installed
- Full DuraFlex liner replacement (typical 20-30 ft run): $1,400-$2,800
- Fireplace insert service and venting verification: $150-$300
- Firebox or damper repair alongside DuraFlex service: $200-$650
What moves the price: access to the chimney (steep roofs or difficult ladder setups on Paterson’s three-story rowhouses cost more), the length and diameter of the liner, and whether we find hidden damage the camera reveals. Nothing gets recommended without camera evidence you can see. Call (862) 356-5229 for a free estimate - we’ll give you a written price before we lift a tool.

Why Paterson Homeowners Call Level Two Chimney Paterson for DuraFlex Work

Paterson homeowners don’t call us because we’ve been around. They call us because we show them the footage. That’s the whole proposition, and it’s been that way since 2009 when we made camera-scan documentation standard - not because regulators required it, but because a flashlight look tells you nothing about a DuraFlex liner. We’re independently owned and operated under the Haven Standard, and every DuraFlex job comes with Clause 4: a documented photo record on every visit. Our techs know DuraFlex liner specs, the common installation mistakes, and when to use HeatShield or Gelco alternatives. Most importantly, we give you a written price before we start - always, no exceptions. Brought to you by a crew that’s worked steadily across Paterson, including the older row houses near the Great Falls Historic District where the original masonry is beautiful and the flue conditions are rarely straightforward.
FAQs
We’re an independent DuraFlex service provider, so we don’t process manufacturer warranty claims directly, but we document every repair with photos and measurements that support your warranty submission. If the DuraFlex defect is covered, we’ll provide the evidence you need. If it’s not, we’ll show you why and quote a written repair. Call (862) 356-5229 for an exact quote - estimates are free.
A properly installed DuraFlex 316Ti liner typically lasts 15-25 years in Paterson’s climate, but the tee connection and cap often need service sooner. The freeze-thaw cycles and the moisture off the Passaic River are harder on the external components than on the liner body itself. We’ll show you exactly where your liner is in that lifespan during the camera scan.
Small sections - typically the tee, a transition collar, or the termination cap - are repairable. A kinked liner, a liner with widespread pitting, or a liner that’s the wrong size should be replaced, not patched. The camera footage tells us which one you have, and we won’t recommend replacement unless we can show you why on the screen.
Most DuraFlex diagnostic visits are scheduled within 3-5 business days, and repairs are completed the same day if parts are in stock. We keep common DuraFlex components - tees, caps, and collars - on our trucks. For full liner replacements, we typically order specific lengths and schedule the job within one to two weeks. We’ll tell you the timeline in writing before anything is scheduled.
Yes. DuraFlex venting shows up on many residential gas fireplaces in Paterson, and we service the full setup: gas log sets, venting, caps, and termination. The camera scan and draft test are done on every gas installation too - CO risk doesn’t care what fuel you burn. Call (862) 356-5229 for a free estimate and a written price before any work begins.
