That matters because we recommend what your flue actually needs, whether that’s a genuine DuraFlex component or an honest full replacement.

Why Irving Residents Choose Us for DuraFlex Service
DuraFlex liners show up in a lot of Irving homes, from 1970s brick veneer ranches off Story Road to newer two-story builds in Valley Ranch. Hank Delano, owner at Flint Chimney Co Dallas, learned the trade at Los Angeles Trade-Technical College and has spent nearly two decades applying that education to North Texas chimneys. He’s seen how original clay tile liners in Irving’s older homes crack under expansive soil movement, and how DuraFlex retrofits perform once installed inside those compromised flues.
We keep genuine DuraFlex components on hand for Irving work: liners, connectors, top plates, and rain caps. When your existing system needs matching parts for warranty compliance and proper fitment, we use them. When corrosion or deformation has gone past safe repair limits, we say so plainly and quote a full replacement instead of padding the ticket with patchwork. That’s how we operate across the Irving service area, and it’s why our work carries a 365-Day Done Right Promise in writing.
Every technician who walks through an Irving door is background-checked and uniformed. A live person answers the phone 24/7. And the price you approve before work starts is the price on the invoice. No exceptions.

Common DuraFlex Chimney Cleaning Problems We Solve in Irving
- Stage 3 creosote glazing in low-use fireplaces. Irving’s humid subtropical climate means fireplaces burn sporadically, and sporadic burning produces exactly the conditions for glazed creosote. The corrugated inner walls of a DuraFlex 316L liner trap those deposits, and standard wire brushes skate over the shiny surface without removing it. We use rotary whips and mechanical removal to cut through the glaze.
- Liner kinking and ovaling in mid-century flue offsets. Freeze-thaw cycles in Irving winters shift brick veneer homes on expansive clay soil. That movement transfers to flue offsets, and a DuraFlex liner installed through an offset can kink or oval. We identify these restrictions during inspection and correct them before they become draft failures or carbon monoxide risks.
- Pinhole corrosion at the welded seam. Acidic creosote plus Irving’s high spring humidity creates condensation in seldom-used chimneys. That moisture settles in the corrugations and eats at the seam of a DuraFlex liner. Pinholes near the bottom third of the liner are a classic failure we find in older Irving installations.
- Improperly terminated liners at the crown. Many DuraFlex retrofits in Irving were terminated without proper crown flashing or rain caps. Water gets behind the existing clay tile and accelerates spalling. We replace termination components and correct crown detailing so the liner actually sheds water.
- Uninsulated annular space between liner and clay tile. This is the condition we catch constantly in Valley Ranch and Las Colinas homes where a DuraFlex liner was pulled through original 1980s clay tile. Without insulation in that gap, condensation forms on the liner exterior and rusts it from outside in. We identify this during cleaning and show you exactly what’s happening.
DuraFlex Service in Irving: What Local Conditions Mean for Your Equipment
Here’s the Irving-specific fact that shapes how we approach DuraFlex cleaning in this city: many homes in Valley Ranch and Las Colinas have fireplace flues that still contain original 1980s builder-installed clay tiles, and when a DuraFlex liner was later added, the annular space between liner and tile was often left uninsulated. We routinely correct that condition during cleaning by identifying condensation and corrosion that other sweeps miss, because the liner’s exterior rusts from trapped moisture even when the interior looks passable. That’s not a generic chimney problem; it’s what happens when North Texas humidity meets 40-year-old masonry and a flexible stainless liner without insulation. In Irving, a visual inspection of the flue interior only tells half the story. We check the full system because we know where this city’s chimneys fail.
Hank’s crew once pulled a 6-inch DuraFlex 316L liner from a 1978 brick veneer home off O’Connor Road after the homeowner noticed fine rust-colored dust on the hearth. The corrugated wall was heavily glazed with Stage 3 creosote, and pinhole corrosion had punched through the seam where condensation pooled. We completed full mechanical removal with rotary whips, then installed a new DuraFlex Pro Connect system with a multi-flue cap to stop recurring water intrusion. The homeowner now understands exactly what was happening inside that flue.

FAQs – DuraFlex Chimney Cleaning in Irving
Irving’s sporadic fireplace use creates exactly the conditions for Stage 3 glazed creosote. When you burn only occasionally, flue temperatures stay low, and combustion byproducts condense on the corrugated inner walls of your DuraFlex liner instead of burning off. The glaze hardens and standard brushes can’t remove it. We use rotary mechanical cleaning to cut through it, and we’ll show you the difference on camera before and after. Call (361) 492-4099 to schedule a sweep before the next burning season.
Yes. We run a Level 2 video camera inspection through the DuraFlex liner itself and, where access allows, into the annular space between liner and original clay tile. That’s how we identify the uninsulated liner condition common in Valley Ranch and Las Colinas homes without touching your masonry. You get a photo report showing exactly what we found.
Pinholes near the bottom come from acidic creosote mixing with condensation that pools in the corrugations, then eating through the welded seam. Irving’s spring humidity makes this worse in chimneys that sit unused for months. Pinholes mean the liner’s structural integrity is compromised, and patching doesn’t restore it safely. We recommend replacement with a new DuraFlex system, and we’ll quote it honestly in writing before any work starts. Call (361) 492-4099 for a free assessment.
Yes, and the reason is Irving’s usage pattern, not your burning frequency. Prefab fireplaces with DuraFlex liners still accumulate creosote from low-temperature fires, and the corrugated liner walls trap it effectively. Occasional use makes glazing more likely, not less. An annual sweep catches buildup before it becomes Stage 3 glaze, and it’s far cheaper than liner replacement down the road.
We determine insulation status during a Level 2 inspection by checking the annular space between liner and clay tile and looking for condensation patterns on the liner exterior. In Irving’s humid climate, an uninsulated liner rusts from outside in even when the flue interior looks clean. That’s the hidden condition we routinely correct in Valley Ranch and Las Colinas, and it makes the difference between a liner that lasts 15 years and one that fails in 10. Call (361) 492-4099 to get it checked before the next humid spring.
