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 reliable stainless steel chimney liners and factory-built fireplace components, but Fort Worth’s clay soil movement, summer heat cycling, and occasional ice events stress these systems in predictable ways. Here’s what we find on actual DuraFlex jobs:
- DuraFlex SW (Smooth Wall) liners develop creosote bridging at the flex-to-rigid transition. The SW series has a smooth interior that sheds creosote well until it meets the rigid connector near the thimble. In Fort Worth, where homeowners burn seasoned post oak and pecan, we see thick Class II or III creosote accumulate right at that joint, restricting draft. We remove it mechanically with a rotary system sized to the SW’s .005″ wall, then verify clearance with a camera scan before we sign off.
- DuraFlex Pro liners in two-story Colonial Heights homes show premature corrosion at the rain cap. The Pro series uses 316Ti stainless, but if the original installer used a generic cap instead of DuraFlex’s vented model, condensation pools in the collar. We replace with a proper vented cap or, if the damage extends below the first joint, cut back and re-terminate with an OEM-grade adapter. The camera doesn’t lie - and neither does the written estimate.
- DuraFlex factory-built fireboxes in 1980s Ridglea Hills ranches suffer refractory panel cracking. These units use lightweight refractory cement panels that shrink and crack after repeated thermal cycling. Hairline cracks under 1/8″ can be repaired with HeatShield refractory sealant; anything wider requires panel replacement. We source DuraFlex-compatible panels through our Haven buying network, or fabricate to spec if the series is discontinued.
- DuraFlex gas inserts in newer Fairmount homes lose pilot reliability due to flex-line degradation. The insert’s stainless flex connector, routed through a tight chase, rubs against framing or the DuraFlex liner collar. After 8-12 years the braided sheath fails, causing intermittent pilot outages we diagnose with a manometer test. We replace with a DuraFlex-listed or Gastite equivalent, secured with proper stand-offs, and leak-test to 0.5 psi.
- DuraFlex tee-body connections separate during Fort Worth’s spring clay swell. When the chimney structure shifts, the tee that connects the liner to the appliance can pull apart at the band clamp. We find this most often in homes near the Trinity River floodplain with active foundation movement. We reseat with a new band and locking tab, then add a support plate if the original installer skipped it - which they often did.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers, 24/7. We ask for the DuraFlex model or series if you know it, the fuel type, and what’s happening. We book a two-hour arrival window.
- 2
NFPA 211 Level 2 inspection. Corrine Halstead’s crews camera-scan the flue, inspect the firebox and smoke chamber, and photograph every finding. You see what we see in real time.
- 3
Written scope and price. Before any tool touches your system, you get a written price, written scope, and written warranty - Haven Standard Clause 1. If we recommend a DuraFlex OEM part over a quality aftermarket equivalent, we explain the trade-off in dollars and warranty coverage.
- 4
Repair with documentation. We complete the work, pressure-test or draft-test as applicable, and record post-repair photos. The photo record goes into your file under Haven Standard Clause 4, same as we’ve done since 2009.
- 5
365-Day Done Right Promise. If it’s not done right, we make it right. The promise is stamped on your invoice, not buried in fine print.

Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our Fort Worth calls involve DuraFlex systems in homes built or renovated between 1995 and 2015. Our techs carry DuraFlex, HeatShield, and Gelco parts on most trucks, so we’re not ordering blind and billing you for two trips. Every technician is background-checked, uniformed, and assigned by name - you’ll get a text when they’re on the way. We also service HeatShield and Gelco systems for homeowners comparing liner options. As an independent DuraFlex service provider, we have no manufacturer quota pushing us toward replacement when repair is the honest call.
FAQs
DuraFlex warranties the liner or component against manufacturing defect, not against installation error, creosote damage, or normal wear. If your DuraFlex liner failed because of a bad original install - missing support plate, wrong cap, improper sizing - that’s not a warranty claim. We document the actual cause with camera footage so you know before you spend time on a claim that won’t pay.
We source both. For warranty-active systems, we use DuraFlex OEM parts to preserve coverage. For out-of-warranty units, we often recommend quality aftermarket equivalents from our Haven buying network - same 316Ti stainless, same UL listing, lower cost. We put both options in writing with the price difference before you decide.
Replacement makes sense when the firebox or liner has through-corrosion, the refractory panels are no longer manufactured, or multiple previous repairs have compromised the structure. Repair is usually viable for isolated cracks, localized corrosion, or component failures like dampers and blowers. We show you the camera footage and explain which category you’re in - no replacement pitch without evidence you can see.
Once per burning season if you use it regularly, per NFPA 211. Fort Worth’s mild winters mean some homeowners burn only 20-30 fires per year and can stretch to every two years if they’re burning dry hardwood and the camera shows clean flue walls. We check with a Level 2 scan and tell you honestly whether this year’s sweep can wait.
Gas units don’t creosote, but the burner orifices clog with dust and spider webs, the thermocouple weakens, and the flex connector degrades. The real risk is incomplete combustion producing carbon monoxide, or a failed safety shutoff letting gas accumulate. A DuraFlex gas insert is not maintenance-free - it’s maintenance-different. Call (682) 499-2712 for an exact quote; estimates are free.
