DuraFlex Chimney Cleaning Service in North Hollywood, CA

Why North Hollywood Homeowners Choose DuraFlex Chimney Cleaning

We provide independent DuraFlex chimney cleaning, inspection, and repair service throughout North Hollywood, with the depth to diagnose liner problems most sweeps miss. Our crew has pulled and re-set enough DuraFlex stainless liners to know how they fail in Southern California heat cycles, from warped male crimp collars to insulation wrap eaten away by condensation. Because we’re an independent DuraFlex service provider, not an authorized dealer, we inspect and repair what’s actually there rather than defaulting to a full liner replacement every time. If your DuraFlex liner is underperforming, call (833) 589-9860. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Why Trust Ashford Chimney Sweep for Your DuraFlex Chimney Cleaning?

DuraFlex is a flexible stainless steel chimney liner, and working on it correctly takes more than a brush and a flashlight. Our technicians know how these liners behave after years of heat cycling in the dry San Fernando Valley climate: how the crimp collars seat at the appliance connector, how the insulation wrap degrades, and where leaks actually start. Dennis Duran grew up in the Lankershim Arts District neighborhood of North Hollywood and has spent most of his working life within a few miles of where he was raised. He trained in building and construction technology at Los Angeles Valley College, then spent the better part of a decade in the trade before starting Ashford Chimney Sweep in 2012. That background means we treat a DuraFlex liner as part of the whole chimney system, not an isolated component. We repair what we find, and we won’t sign off until the connection, the liner, and the flue are all working together safely.

Common DuraFlex Chimney Cleaning Problems We Fix in North Hollywood

• Degraded insulation wrap on SS liner sections. The aluminum-foil outer wrap and insulation blanket on insulated DuraFlex flex liner break down over time from flue-gas moisture and heat cycling. Once sections go uninsulated, flue gases cool too quickly and creosote starts building up faster than it should. We re-insulate or replace affected sections based on what the camera shows.
• Crushed or separated male crimp collars at the firebox connection. Older two-ply and three-ply flex liner sections develop kinked, crushed, or separated collars at the bottom connector. The result is smoke and gas leakage at the appliance collar, plus a connection that’s nearly impossible to seal properly. A new DuraFlex connector and a proper re-set usually solves it without a full reline.
• Rusted or loosened top plates and storm collars. At the roof penetration, water tracks down between the liner and the original clay tile flue when the top plate loosens or rusts. In North Hollywood that water sits on the masonry crown and slowly rots it. We replace the top plate, bed the storm collar correctly, and address any crown damage before it spreads.
• Pulled-apart liner joints after seismic movement. Liner sections connected in a tight chase can separate at the joints after the ground moves. A Level 1 camera pass misses these gaps; a Level 2 inspection is what catches them. If you’ve felt a quake and your fireplace suddenly drafts poorly, this is one of the first things we check.
• Creosote and ash accumulation in Direct Vent gas inserts. Even gas-burning DuraFlex Direct Vent systems collect ash, dust, and soot over time, especially in a house that’s been shut up through a long San Fernando Valley summer. The chimney doesn’t lie. It shows you exactly what’s been going on up there. A cleaning and vent check restores airflow and keeps burn-off from smothering the flame.

DuraFlex Parts & Our Repair-vs-Replace Approach

We source DuraFlex OEM liner components: male crimp collars, top plates, and appliance connectors for any safety-critical connection on wood-burning systems. Where an OEM part is no longer in production, we use quality aftermarket stainless or high-temp sealant that’s fit for the application. We do not stock or supply genuine DuraFlex parts as a dealer would, and we’re not an authorized DuraFlex service center. What we do is make sensible repair decisions. If a liner is lightly damaged at a joint or an insulation section has failed, we repair it. Full replacement is only the right call when the liner is crushed, split, or uninsulated along most of its length. You’ll see the camera findings yourself before any replacement is recommended. For an honest assessment, call (833) 589-9860. Estimates are free.

Our DuraFlex Service Process – Step by Step

1. 1
   Camera inspection first. We run a Level 1 or Level 2 camera inspection of the entire flue, paying close attention to liner joints, crimp collars, insulation condition, and the top plate at the roof line. You see the footage, not just our summary.
2. 2
   Diagnosis and a written repair plan. If we find a separated joint, a crushed collar, or a failed insulation wrap, we write up exactly what needs to happen, which parts we’ll use, and what can wait. You approve the written estimate before any work begins.
3. 3
   Repair, re-set, or full reline as needed. For a failed collar we re-set the bottom section with a new DuraFlex connector and high-temp sealant. For degraded insulation we re-wrap or replace affected sections. Full relining is only proposed when the liner is beyond repair.
4. 4
   Testing and verification. After the repair we sweep the flue, run a draft check, and confirm the appliance burns clean. We finish with any needed crown coating or waterproofing so water doesn’t undo the work.

DuraFlex Products We Service & Install in North Hollywood

We install and service DuraFlex SS stainless steel relining systems, including 6-inch and 8-inch pre-insulated chimney liner kits, plus DuraFlex Pro heavy-wall flexible liner for wood-burning applications that require sizing. We also work on DuraFlex Direct Vent concentric kits for gas fireplaces and inserts, and we install DuraFlex chimney cap and top-plate kits sized to the liner. Whether it’s a sweep, a Level 2 inspection, or a liner re-set in a 1920s North Hollywood bungalow, we handle the whole system: flue, liner, cap, crown, and venting.

We Also Service These Brands

DuraFlex is one part of the chimney system, and we’re not single-brand dependent. Our crew also installs and repairs HeatShield ceramic restorative liners as an alternative to full relining, and we use Gelco caps for durable, contractor-specified top protection. That gives you an independent, multi-brand perspective on what’s actually best for your chimney.
