Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Cleaning in Van Nuys, CA | Corona Chimney Sweep
Corona Chimney Sweep provides independent DuraFlex chimney cleaning and inspection across Van Nuys, including the 91405, 91406, 91401, and 91411 ZIP codes. We also offer Van Nuys Chimney Sweep services for all liner types. What sets our DuraFlex work here apart is the volume of sealed-off fireplaces we open up in this city’s older tracts, liners that have not been looked at since the first Bush administration. We clean, inspect, and repair DuraFlex systems without being manufacturer-affiliated, which means we tell you what the stainless actually needs, not what a brand rep wants sold. Call (855) 382-6159 for a free estimate.
Why Van Nuys Residents Choose Us for DuraFlex Service
We have pulled hundreds of DuraFlex liners out of Van Nuys chimneys, and the failures here follow a pattern. The San Fernando Valley’s long, hot off-season means a fireplace sits unused from April through November. Moisture condenses inside the flue, creosote from last winter hardens into a glaze, and the termination components, top plates and caps, take the worst of it. When we arrive at a Van Nuys ranch or tract home, we expect to see cap corrosion before we see liner damage. That local pattern recognition means we diagnose faster and do not recommend work you do not need.
Our owner, Nolan Ferris, grew up in South Corona and learned combustion systems through Norco College’s vocational program before spending well over a decade inspecting flues across the Inland Empire and the Valley. He trains every tech on our Van Nuys crews—and those handling DuraFlex repair in Encino—to classify creosote by stage and show homeowners exactly what they are looking at, because a homeowner who understands the buildup is a homeowner who schedules the next sweep. We are an independent DuraFlex service provider. No manufacturer authorization, no warranty endorsement, just familiarity with how this specific liner system behaves inside mid-century masonry chimneys.

Common DuraFlex Chimney Cleaning Problems We Solve in Van Nuys
- Top-plate gasket failure and cap corrosion. Van Nuys fireplaces idle for eight months, then get hammered on cold December nights. Condensation and debris sit against the stainless termination the entire off-season. We see rusted top plates and failed gaskets more than any other DuraFlex issue in this city.
- Liner joints separating inside original clay-tile flues. Much of Van Nuys is 1940s and 1950s construction. When a DuraFlex liner was dropped into an irregular masonry chase without proper insulation or centering, the joints shift. We find separated seams and backed-out fasteners regularly in these older homes.
- Pinhole corrosion near the firebox connector. Ash, grit, and the occasional winter rain combine with the Valley’s hot-dry cycles to eat at the stainless right where it connects to the appliance. This is the spot we camera first on every DuraFlex inspection in Van Nuys.
- Blocked or crushed liner sections from nesting. A fireplace that goes unused for months is an open invitation. Missing or damaged cap screens let birds and squirrels in. We have pulled enough nesting material out of DuraFlex liners in Van Nuys to fill a dumpster.
- ‘Ghost chimney’ liner neglect. In the older tracts around the 91405 and 91406 ZIP codes, fireplaces were often sealed off during remodels. If that chimney had a DuraFlex liner installed before the wall went up, the liner’s condition and termination are completely unknown to the current owner. We find these constantly.
DuraFlex Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here is something specific to Van Nuys that you will not find on a generic DuraFlex page. The 91405 and 91406 tracts are full of what we call ghost chimneys, fireplaces that were sealed or converted during remodels decades ago, leaving the flue and any liner inside it hidden behind drywall. The current owner often has no idea the chimney exists. If that chimney was fitted with a DuraFlex liner in, say, the mid-1990s, and then sealed off during a kitchen or living room remodel, that liner has been sitting untouched for thirty years. The cap may be gone. The top plate may be rusted through. Birds may have built in it. And because the fireplace is hidden, the homeowner never schedules a sweep, never sees the rust streaks on the exterior, never smells the damp draft. The only way to confirm whether that hidden DuraFlex system is safe to use or properly decommissioned is a Level 2 camera inspection. We run the camera, we show you the footage, and we tell you plainly whether that ghost can stay buried or needs work. No other city in our service area has this concentration of sealed mid-century fireplaces, and it changes how we approach every DuraFlex cleaning call here.
DuraFlex Models & Products We Service in Van Nuys
We work on the full DuraFlex line you are likely to find in a Van Nuys home. That includes the DuraFlex Pro Flexible Stainless Liner, the DuraFlex SW smooth-wall liner, the DuraFlex Insulated Flexible Liner Kit, and DuraFlex stainless steel chimney caps. For critical connections, top plates, caps, and connectors, we stock genuine DuraFlex components on our trucks so Van Nuys calls do not wait on a parts shipment. Where a genuine part is discontinued or back-ordered, we use only listed, equal-quality aftermarket replacements. If the liner itself is sound but the cap or top plate is failing, we repair. If the stainless is pitted through or the joints are compromised, we recommend a full reline, not a patch that will fail in two seasons. For broader DuraFlex sales & service, we are your independent local crew, no brand authorization required.

FAQs – DuraFlex Chimney Cleaning in Van Nuys
A DuraFlex liner installed in the 1990s is pushing thirty years old, and in a 1950s Van Nuys masonry chimney it has been through three decades of Valley heat cycling and off-season moisture. The liner may be perfectly sound, but the cap, top plate, and gaskets from that era are almost certainly degraded. The only way to know is a Level 2 camera inspection, and that is where we start. Call (855) 382-6159 to schedule one.
Because the fireplace sits idle for eight months of Van Nuys summer, and during that time condensation forms inside the flue and sits against the stainless cap. Add the Valley’s dry heat and occasional winter rain, and the cap corrodes even with no fires. This is the most common DuraFlex failure we see in Van Nuys, and it is a straightforward cap and top-plate replacement. Call (855) 382-6159 for a quote; we stock DuraFlex caps on the truck.
Yes, and this is exactly the ghost chimney situation we deal with constantly in the 91405 and 91406 tracts. We run a camera through whatever access point exists, or we open one if the chimney is fully sealed. The inspection tells you whether the liner is intact, whether the termination is compromised, and whether the chimney can be safely used or should stay decommissioned.
A Level 1 inspection covers what we can see and reach, the accessible portions of the flue, cap, and firebox. A Level 2 adds a full camera scan of the entire liner interior, and it is required when a home changes hands, after a chimney fire, or when the chimney has been unused or hidden for years. In Van Nuys, where ghost chimneys are common, we recommend Level 2 on almost every DuraFlex call. Call (855) 382-6159 and we will tell you which level fits your situation.
We stock genuine DuraFlex caps and top plates on our Van Nuys trucks for the common sizes, and carry the same inventory for our DuraFlex service in North Hills. If the failure is the cap or gasket and the liner is sound, we can usually complete the repair the same day we diagnose it. Full relines are scheduled, not same-day. Call (855) 382-6159 with your chimney’s details and we will confirm what we can bring.
