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 Citrus, CA | Hickory Chimney Sweep
We’re an independent chimney service company that cleans and repairs DuraFlex systems across Citrus, and the short answer is this: DuraFlex liners in this area fail in specific, predictable ways because of the dry summers, the Santa Ana winds, and the river-rock chimneys so many Citrus homes were built with. We know those failure modes from field work, not a brochure. Call (855) 554-2841 for a free estimate, and we’ll tell you exactly what your flue looks like before we touch anything.
We are not affiliated with, authorized by, or endorsed by DuraFlex. What we are is a local crew that has worked on enough DuraFlex liners, caps, and factory-built chimney stacks across the San Gabriel Valley to know what holds up and what doesn’t.

Why Citrus Residents Choose Us for DuraFlex Service
Most chimney companies in Citrus can run a brush through a flue. Fewer can tell you why a DuraFlex liner that was installed in 1998 is suddenly drafting poorly, or whether the cap that keeps lifting in a Santa Ana needs a new collar or just better fasteners. We can, because we’ve been inside these systems in homes all over the 91702 ZIP.
Ruben Acosta runs our crew, and he grew up sweeping and inspecting chimneys across East Los Angeles and the foothill neighborhoods east of it. He picked up the mechanical fundamentals at East Los Angeles College, where an instructor pushed him toward duct and flue work because it was the trade with actual staying power. He’s spent the last two-plus decades doing Level 2 inspections and being straight with homeowners about what genuinely needs fixing and what can wait. As he puts it: “Tell me what the flue looks like and I’ll tell you what your winter looks like.”
When we work on a DuraFlex system in Citrus, we inspect it as an installer would and clean it as a sweeper should. That means checking joints, screens, collars, and termination caps, not just brushing soot. We service the whole Citrus service area and stock the common stainless components locally so we’re not making you wait a week for a cap or a connector.

Common DuraFlex Chimney Cleaning Problems We Solve in Citrus
- Joint separation on older flexible liners. DuraFlex liners installed in the 1990s and 2000s often got pulled around offsets in the original clay tile flue. Twenty or thirty years later, those joints start to separate. Citrus has a lot of 1950s to 1970s masonry chimneys with clay liners, and the offset geometry in those older flues is exactly where we see this. We clean the liner, re-secure what’s still sound, and tell you plainly if a section is too far gone to save.
- Brittle, flaky creosote glazed to the liner walls. Citrus summers are hot and dry, and that bakes creosote until it gets hard and glassy. Then it cracks and flakes off in sheets, packing the bottom of the liner and the firebox. We remove it fully rather than leaving a layer behind that’ll re-ignite on a windy winter night.
- Rusted or clogged caps and terminations. Santa Ana winds shove soot, fine dust, and debris into every opening. DuraFlex caps and the stainless termination at the top of the stack corrode faster here than in wetter coastal towns, and the cap screens clog. We replace caps and clean terminations so the whole upper assembly vents and sheds embers correctly.
- Loose caps from wind loading. A DuraFlex cap that wasn’t fastened to the flue collar properly will loosen over time in wind-heavy Citrus, especially on homes near the foothill canyons where Santa Anas channel. We check the collar connection on every sweep and secure it while we’re up there.
- Rust and spalling at the liner transition. Moisture at the crown and at the point where the liner meets the masonry feeds rust on stainless components. On river-rock chimneys, you also get spalling in the stone itself. We inspect the whole top assembly, not just the flue, because one failure usually points to another.
DuraFlex Service in Citrus: What Local Conditions Mean for Your Equipment
Here’s something you’ll only hear from a company that actually works in Citrus: a lot of the chimneys in this area are faced with locally sourced river rock, and that stone holds moisture differently than brick or block. When moisture gets trapped behind the rock and the hot dry summers pull it through, the stone starts to spall, chipping away and loosening. Ruben and our crew have pulled loose stone out of fireboxes more times than we can count, usually because someone ran a brush through without checking the surround first. On a DuraFlex job, we protect and inspect the rock surround before we ever touch the liner. One careless move with a ladder or a heavy brush head can knock stone into the firebox, so we work methodically around it. That’s a Citrus-specific habit, and it’s one you won’t get from a generic chimney outfit driving in from somewhere else.
DuraFlex Models & Products We Service in Citrus
We clean and service the full range of DuraFlex systems you’ll find in Citrus homes. The stainless steel flexible round liners in 6″ and 8″, the insulated flexible liner kits used on wood stoves and inserts, the factory-built twist-lock chimney lengths and fittings, and the rigid stainless liner sections for straight masonry flues. When parts need replacing, we source DuraFlex-compatible stainless components and quality aftermarket liners and caps, and we specify factory OEM-style parts where fit and listing demand it. If a liner is kinked but otherwise sound, we clean and re-secure it. If it’s crushed, split, or rusted through, we tell you it needs replacement instead of patching it for another season.
On a 1950s home near the foothills in 91702, we pulled a DuraFlex flexible liner that had been kinked around an offset in the original clay tile flue and found glazed creosote flaking off in sheets. We swept and removed the creosote, re-secured the liner, and replaced a rusted cap, then inspected the river-rock surround so no stone came loose during the work. The homeowner got a draft-safe flue for the winter and a written record of the liner condition for next year’s sweep.

DuraFlex chimney cleaning in Citrus depends on the condition of the liner and the cap, not just the size of the flue. A straightforward sweep with a sound liner and a secure cap runs on the lower end. A liner with heavy glazed creosote, a clogged termination, or a loose cap takes longer and costs more. We quote a flat price before we begin, and the estimate is free.
What you get with the estimate: a full inspection of the liner, the cap, the crown, and the river-rock surround, plus a camera view you can see with your own eyes. Nothing gets recommended without visual evidence. Call (855) 554-2841 for an exact quote for your Citrus home.

FAQs – DuraFlex Chimney Cleaning in Citrus
No. We clean most DuraFlex flexible liners in place, using brushes sized to the liner and running them through the full length. We only pull a liner when it’s failed mechanically, and you’ll see why on the camera before we touch it.
The cap isn’t secured to the flue collar properly, or the collar itself has corroded. Santa Ana wind loads on a DuraFlex cap are real, and a loose cap rattles, leaks, and eventually lifts. We fasten or replace it while we’re up there, so it stays put through the next wind season. Call (855) 554-2841 and we’ll get it handled.
Yes, and it’s more dangerous in this climate than most people realize. Citrus’s hot dry summers turn creosote brittle and flaky, and that loose material sits at the bottom of the liner ready to ignite. The sweep removes it so you’re not carrying a season of fuel inside the flue. Call (855) 554-2841 to book before burning season starts.
Yes. We inspect the rock first, protect the surround while we work, and never lean ladders or brush the rock face. Loose stone comes out carefully before it falls into the firebox. It’s a slower, more deliberate process, and it’s the only way to sweep a river-rock chimney in Citrus without causing more damage.
We offer Level 1 and Level 2 inspections. A Level 1 checks the accessible portions of the flue and the firebox, and a Level 2 uses a camera to inspect the full liner length, the joints, and the upper termination. For a DuraFlex system in a 1950s to 1970s Citrus home with an original clay tile surround, we usually recommend Level 2 because you need to see joint separation before it becomes a draft problem. Call (855) 554-2841 to talk through what your chimney needs.
