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
We’re an independent chimney service in Van Nuys that cleans, inspects, and repairs DuraFlex stainless steel liner systems. The big difference with our crew: we don’t just sweep the flue and leave. We know how a DuraFlex liner seats into a mid-century Van Nuys chimney, what a loose cap on a ranch home off Hazeltine Avenue actually lets in, and when a cracked crown is putting water on your liner. Call (833) 958-9616 for a free estimate on DuraFlex cleaning or repair anywhere in Van Nuys.
Why Van Nuys Residents Choose Us for DuraFlex Service
Plenty of sweeps can run a brush through a flue. Fewer can tell you why your DuraFlex cap keeps loosening, or whether the rust staining at your top plate matters. Our owner, Harold Lawson, grew up in Arleta and spent more than a decade pulling creosote and raccoon nests out of San Fernando Valley chimneys before opening this company in 2017. He learned the trade at Los Angeles Valley College just over in Valley Glen, and he still runs a camera through every flue so you see what we see. We’re independent, which means we tell you straight what a DuraFlex liner needs and what can safely wait. No factory script, no upsell. That’s how we’ve always worked in Van Nuys.

Common DuraFlex Chimney Cleaning Problems We Solve in Van Nuys
- Loose caps and top plates after earthquakes. Van Nuys sits in the San Fernando Valley, and even small seismic events walk fasteners loose on older chimneys. A DuraFlex cap that rattles or shifts lets rain and birds into the flue, and that water runs straight down the liner.
- Animal nests packed against the top plate. Attic raccoons and birds love uncapped or loosely capped flues. On a ranch home off Hazeltine Avenue in 91401, we pulled a DuraFlex SW liner installed under a loose cap and found raccoon nesting packed against the top plate, plus a crown crack the homeowner couldn’t see from the driveway.
- Heat-cycled seams collecting creosote. Valley cold snaps push older fireplaces harder than they were built for. Stainless seams that separate from repeated heating and cooling let creosote collect behind the liner wall, which is exactly where you don’t want it.
- Cracked top-plate sealant under summer heat. Santa Ana UV and 100-degree Valley summers bake sealant until it shrinks and splits. Water seeps down around the liner and corrodes the flue collar.
- Liner corrosion from undetected crown cracks. In the older 91401 and 91405 blocks, hairline earthquake cracks in clay-tile flues and mortar crowns often hide behind a DuraFlex install. Invisible from the ground, they leak silently onto the stainless for years.
DuraFlex Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s what we see over and over in the 91401 and 91405 neighborhoods: a DuraFlex liner installed behind a clay-tile flue that looks fine from the roofline but is quietly carrying water. The mid-century homes in this part of Van Nuys went up between 1945 and 1970. Their original crowns and tile joints have been through decades of seismic movement, Valley heat, and Santa Ana wind. Hairline cracks develop. They don’t show up on a visual glance. They show up on a camera run, which is why every DuraFlex service call we do includes one. If you can’t tell me what’s in your flue, that’s exactly the problem. We run the camera, you see the condition in real time, and we talk through what actually needs doing. Sometimes that’s a sweep and reseal. Sometimes it’s a top-plate replacement. Either way, you’ll know why.
DuraFlex Models & Products We Service in Van Nuys
We service the DuraFlex stainless flex-liner systems most commonly found in Van Nuys chimneys: the SW smooth-wall liner kits, Pro single-wall 316L flexible liner, ThermoFLEX insulated liner kits, and round and multi-flue stainless caps. When we size a replacement DuraFlex liner, we measure the existing flue and match the liner to it so clearances stay correct. If a liner is sound, we clean and re-seat it. If the top plate is done for, we’ll set a new one that fits the existing assembly properly. We’re an independent service provider, not manufacturer-affiliated, so we pick quality parts that fit the actual chimney in front of us rather than whatever a brand program tells us to sell.

FAQs – DuraFlex Chimney Cleaning in Van Nuys
Yes. We’re independent, so we service DuraFlex systems regardless of who installed them. We’ll clean, inspect with a camera, and tell you honestly what’s holding up and what isn’t. Call (833) 958-9616 and we’ll schedule the assessment.
Van Nuys sits in the San Fernando Valley, and earthquake movement plus repeated heating and cooling loosens cap fasteners over time. The fix is usually a properly seated top plate with fasteners torqued correctly, not just tightening the old hardware and hoping. We re-seat caps so they stay put through the next cold snap.
If you’ve lived in the home a few years and haven’t had the flue camera-run, you should get a Level 2. A Level 2 inspection goes beyond what a Level 1 visual pass can see, which matters in older Van Nuys homes where crown cracks and liner corrosion happen out of sight. We’ll recommend what’s appropriate after we see the chimney.
No. Stainless doesn’t rust on its own. Rust staining usually means water is getting in, often from a cracked crown or a failed top-plate seal above the liner. We’ll trace the water source and tell you what repair actually stops it. Call (833) 958-9616 for a free estimate.
In most cases, yes. Crown cracks are repaired from the top, and the liner usually stays in place. We seal the crown, check the top plate, and re-seat the cap. If the liner itself is torn or crushed, that’s a different conversation, and we’ll show you the camera footage before recommending replacement.
