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 | Corona Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and liner service across Citrus, CA, and DuraFlex repair in Irwindale. The one thing that makes our DuraFlex work here different: Citrus sits against the Angeles National Forest, and a properly swept and documented DuraFlex flue is a WUI fire-hardening measure, not just routine maintenance. Homeowners in 91702 call (855) 382-6159 when they need a DuraFlex-lined chimney cleaned, inspected, or repaired before wildfire-insurance inspectors show up. We’re not manufacturer-affiliated. We’re a local chimney crew that works on the DuraFlex systems already installed in Citrus homes, and we repair what we find.
Why Citrus Residents Choose Us for DuraFlex Service
DuraFlex stainless liners are built to handle the retrofits this foothill housing stock demands. Most Citrus chimneys date to the 1940s and 1960s, before modern flue-liner requirements existed. A lot of those original brick chimneys now carry flexible stainless liners installed when wood stoves or inserts got added later. Our techs have pulled, swept, and reset those liners in enough Citrus ranches and bungalows to know the failure patterns before we even drop a camera down the flue.
Nolan Ferris, our owner, grew up in South Corona and learned combustion systems through Norco College’s vocational program before narrowing his focus to chimneys. He’s spent well over a decade working flues across the Inland Empire, and his methodical approach to creosote classification means you see exactly what stage of buildup you’re dealing with, not just a bill for brushing. When we work on a DuraFlex liner in Citrus, we document its condition the way an insurer’s inspector would want to see it. For more on the liner systems we install and service across the region, see our DuraFlex sales & service page.

Common DuraFlex Chimney Cleaning Problems We Solve in Citrus
- Crushed or kinked flexible liners at the smoke-chamber transition. Mid-century Citrus ranches often had fireplace inserts retrofitted into undersized original flues. The DuraFlex flex liner snakes down through the smoke chamber and can kink where the angle tightens. That kink traps creosote behind it and restricts draft. We cut out the crushed section, sweep the flue, and reset the liner properly.
- Corroded or loosened top plates and cap screens after Santa Ana wind events. Dry seasonal winds work hardware loose. A loose cap screen lets embers and debris into the flue. With the Angeles National Forest at the back fence, that’s not a small thing. We inspect caps on every DuraFlex service call in Citrus.
- Failed liner-to-appliance connectors and warped dampers upstream of the DuraFlex liner. The liner itself might be fine while the connector or damper upstream has failed. Cool foothill evening burns create draft problems that glaze creosote inside the liner. We check the whole vent path, not just the pipe.
- Insulation settling or separating in older installations. Liners installed a decade or two ago show gaps where insulation has settled, exposing the original brick to heat and creosote. Level 2 inspections prompt by county venting standards catch this regularly in Citrus.
- Glazed creosote built up from intermittent weekend burning. Citrus gets a real winter fire season, but most people burn on weekends, then let the flue sit. That cycle produces tinder-dry creosote layers by fall. We classify the creosote stage and show you what it means for draft and fire risk.
DuraFlex Service in Citrus: What Local Conditions Mean for Your Equipment
The WUI roof-and-vent standards in Citrus change what a DuraFlex service call actually has to accomplish. This isn’t just a sweep-and-go market. Wildfire-insurance inspections in the 91702 foothill neighborhoods cite the county’s WUI venting requirements, which means a DuraFlex reline here often has to satisfy venting specs, not just pass a visual check. Our Level 2 inspections document the liner, cap, and connector condition with a camera report you can hand straight to an insurer’s inspector. We’ve seen insurers flag older brick chimneys after dry Santa Ana seasons, forcing relines or cap upgrades. A documented DuraFlex system with a tight top plate and proper screening is the answer. If you can’t see daylight through the damper, we need to talk before you light that first fire of the season. The Citrus service area we cover includes the foothill streets where this inspection pressure is strongest.
DuraFlex Models & Products We Service in Citrus
We work on the DuraFlex systems most common in Citrus retrofits: the Stainless Steel Chimney Liner Kit in both flexible and insulated configurations, the Pro Flexible Liner in single-wall and insulated versions, Rigid Reline Pipe sections where an older chimney needs straight runs, and Top Plate and Cap assemblies. Parts strategy comes down to fit and venting. We lean on OEM DuraFlex liner, cap, and top-plate components where matching matters for a tight seal. Where OEM adds cost without benefit, we use quality aftermarket connectors and dampers. If a DuraFlex liner is sound, we repair the cap, crown, or connector around it. If it’s crushed, kinked, or gapped, honest replacement beats patching it into a fire-safe state.

FAQs – DuraFlex Chimney Cleaning in Citrus
No. We’re an independent chimney service company in Citrus that installs, inspects, and services DuraFlex products because they fit the retrofits this market demands. We are not authorized, sponsored, or endorsed by DuraFlex. What we bring is hands-on familiarity with how their liners and caps behave inside the original 1940s-1960s brick chimneys common in 91702.
A Level 2 inspection means we run a camera through the entire flue path, including the smoke chamber transition, documenting the DuraFlex liner’s condition, the top plate, the cap screen, and the connectors. You get a written report with photo documentation. In Citrus, that report is what wildfire-insurance inspectors and WUI venting checks want to see. Call (855) 382-6159 to schedule one before your insurer sends someone out.
Most cleaning calls take 90 minutes to two hours, including setup, sweeping, and inspection of the cap and liner. If we find a problem that needs repair, like a crushed liner section or failed top plate, the repair gets scheduled separately, usually with parts sourced within a few days. We don’t rush the job and we don’t leave you with a chimney that isn’t safe to burn.
We service the Stainless Steel Chimney Liner Kit in flexible and insulated forms, the Pro Flexible Liner in single-wall and insulated configurations, Rigid Reline Pipe sections, and Top Plate and Cap assemblies. If you’re not sure which DuraFlex system your Citrus home has, we’ll identify it during the inspection and tell you what parts we’d use if repairs are needed.
Full liner replacement with an insulated DuraFlex kit starts around $2,500 for a typical single-story Citrus ranch and goes up based on chimney height, roof access, and whether the smoke chamber needs work; we also handle DuraFlex in Covina. If the existing liner is sound, cap and top-plate replacements run far less. Call (855) 382-6159 for a free estimate, and we’ll show you the camera footage before recommending anything.
