Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Van Nuys Residents Choose Us for DuraFlex Service
DuraFlex stainless liners and caps show up in a lot of Van Nuys fireplaces, mostly in those 1940s-to-1960s ranch homes where the original clay tile liner got retrofitted years ago. We’ve worked on enough of them to know the failure points by heart: the bottom joint where condensation eats at the steel, the cap screens that clog after the first big wind, the dampers that seize from months of disuse. Norm Castillo, our owner, has been working chimneys and venting systems across the San Fernando Valley, including DuraFlex repair in Encino and beyond, for close to two decades, and he’s the one homeowners call when a fireplace hasn’t been touched in years and nobody can figure out why it’s smoking. We stock OEM DuraFlex caps, top plates, and liner couplings locally so we’re not waiting on a parts shipment when your flue needs attention. Clean, inspect, repair, in one call.

Common DuraFlex Chimney Cleaning Problems We Solve in Van Nuys
- Corrosion pitting at the liner’s bottom joint. Van Nuys summers are hot and dry, and fireplaces go unused from May through October. Condensation settles at the lowest point of the DuraFlex liner and sits there for months. By the time the first cold snap hits, that joint can be pitted enough to warrant a camera inspection.
- Cap and spark arrestor screens packed with debris. Santa Ana winds push leaves, dust, and ash straight down the flue. After one windy night, a DuraFlex cap screen can go from clear to completely blocked, which kills draft and sends smoke back into the living room.
- Cracked or spalled clay tiles pinching the DuraFlex liner. Most Van Nuys homes have original clay tile chimneys with a DuraFlex liner retrofitted inside. Age and minor seismic settling crack those tiles, and a cracked tile edge can abrade the stainless liner over time. We see this regularly during Level 2 inspections.
- Seized or rusted damper assemblies. When a damper sits unused through a long dry summer, the metal rusts and locks up. A damper that won’t close lets debris fall into the firebox, and one that won’t open properly causes smoke spillage on the first fire of the season.
- Smoky smell on hot, still days with no fire lit. This is the call we get more than any other in Van Nuys. The chimney hasn’t been used in months, but the house smells like a campfire. It’s almost always wind-driven debris packed into the smoke shelf or a clogged cap, backing odors into the house.
DuraFlex Service in Van Nuys: What Local Conditions Mean for Your Equipment
Van Nuys sits on the Valley floor, flat and open, so when the Santa Anas blow through in the fall, there’s nothing to break the wind before it hits your chimney cap. We see the pattern every year. Techs working the valley floor, especially in the 91401, 91405, and 91406 ZIPs, routinely find ash pits and smoke shelves so packed with wind-blown leaves, dust, and soot after a Santa Ana night that you’d think the fireplace had been outside. The DuraFlex cap screens take the worst of it. They’re designed to stop sparks, not to shed palm fronds and a half-inch of valley dust, so they clog, draft reverses, and the smell pushes back into the house on days when nobody has lit a fire in weeks. That’s the Van Nuys signature call: a smoky odor on a hot, still afternoon, not an actual fire problem. Homeowners in Woodland Hills or Sherman Oaks DuraFlex service areas get some of this, but those neighborhoods have topography that breaks the wind. Van Nuys gets the full force of it every time the winds shift through the Cajon and San Gorgonio passes, and your DuraFlex cap is the first thing in the way.
We recently serviced a 1950s ranch home in the 91406 ZIP near Van Nuys Airport. The homeowner called about a smoky smell on a completely still day, no fire lit, windows closed. Up top, the DuraFlex cap screen was clogged with palm fronds, dust, and ash from the last Santa Ana event. The smoke shelf below it was packed solid with debris. After clearing the cap and vacuuming out the firebox, we ran a camera down the liner and confirmed the DuraFlex liner was still intact, but we recommended a higher-flow cap to prevent the same blockage from forming next season.
DuraFlex Models & Products We Service in Van Nuys
We service the full DuraFlex residential lineup: the DuraFlex SS Flexible Liner, the DuraPlus chimney system, the DuraTech chimney system, and DirectVent Pro venting. For DuraFlex SS liners, we handle everything from basic creosote removal to camera inspection for pitting, and we replace the bottom-joint sections when corrosion has gone too far. For DuraPlus and DuraTech prefab systems, we inspect the chimney sections, the supports, and the firestop assemblies, since those systems rely on precise component fit. On parts, we use OEM DuraFlex caps, top plates, and liner couplings whenever possible, because a cap that doesn’t seat correctly on an OEM collar creates draft problems from day one. When OEM isn’t available or the price doesn’t make sense for an older system, we’ll recommend a quality aftermarket part and tell you exactly what trade-off you’re making. We stock common DuraFlex cap sizes and coupling sizes locally so most Van Nuys repairs don’t wait on a shipped part.

FAQs – DuraFlex Chimney Cleaning in Van Nuys
Expect us to treat the first visit as a full baseline: a sweep of the liner, removal of the cap for debris clearing, a check of the bottom joint for corrosion, and a camera run if the liner shows any sign of pitting or creosote buildup past a normal level. You’ll get photos and an honest read on whether anything needs repair or if you’re good for another year.
Once a year if you burn wood, and before Santa Ana season starts in the fall, including for our DuraFlex service in North Hills customers. The winds here clog caps and fill smoke shelves with debris even when you haven’t used the fireplace, so an annual fall sweep catches both the creosote and the wind-driven blockage before they cause a smoky-smell day in your house.
Both, depending on the damage. A bent spark arrestor screen can sometimes be repaired. A cap with a rusted-out collar or a broken mounting flange gets replaced, and we’ll use an OEM DuraFlex cap when the liner size and roof configuration call for it. If the cap has failed because of repeated Santa Ana debris loading, we’ll talk about a higher-flow cap design.
Yes, and this is one of the most common calls we handle in Van Nuys. The smell is almost always wind-driven debris sitting in the smoke shelf or a clogged cap screen, not a liner failure. We clear the cap, vacuum the smoke shelf and ash pit, and the odor is gone. If the liner needs attention, the camera will tell us. Call (833) 805-3229 and we’ll schedule it.
A Level 1 inspection is what happens during a routine sweep: we check the accessible portions of the flue, the damper, the cap, and the firebox. A Level 2 adds a camera run through the full liner and chimney, plus checks of the attic and crawlspace clearances. For a DuraFlex system in an older Van Nuys masonry chimney, especially after seismic settling or years of disuse, a Level 2 is the only way to see whether the clay tiles around the liner are pinching it.
