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 Ontario, CA | Corona Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and repair across Ontario, CA. The work here isn’t the heavy creosote removal you’d see in colder climates. It’s post-Santa Ana debris clearing, thin flaky soot from decorative log burning, and cap and screen repair on postwar tract homes. Call (855) 382-6159 for a free estimate.
We’ve swept and repaired hundreds of DuraFlex factory-built fireplace and chimney systems across the Inland Empire, so we know how these metal flues, caps, and spark arrestors actually age in Ontario’s wind-and-heat conditions. We are an independent service provider, not authorized, sponsored, or endorsed by DuraFlex. That independence means we give you a straight answer about what needs fixing now and what can wait. As part of our broader DuraFlex sales & service work, cleaning is where most Ontario homeowners first meet us. The cleaning almost always uncovers something else: a rusted cap, a stiff damper, or a screen that’s let a bird build a nest.
Why Ontario Residents Choose Us for DuraFlex Service
Most chimney companies in the Inland Empire clean flues. Fewer can tell you whether a DuraFlex direct-vent run is still drafting correctly, whether the galvanized cap is original, or whether the screen has rusted past saving. We repair what we find. That’s the difference, and it’s why Ontario homeowners call us instead of a sweep-only crew.
Nolan Ferris, our owner, grew up in South Corona and learned the mechanical side of the trade through Norco College’s vocational program, studying HVAC fundamentals and combustion systems before narrowing his focus entirely to chimneys. He’s spent well over a decade inspecting and cleaning flues across the Inland Empire, and he’s particular about creosote classification. You’ll see exactly what stage buildup you’re dealing with and what that means for draft performance and fire risk. As he likes to say, “If you can’t see daylight through the damper, we need to talk before you light that first fire of the season.”
We carry OEM-spec DuraFlex caps, screens, and termination components where fit and listing matter. For liners and dampers, we use quality aftermarket parts when they match the existing flue geometry. The goal is the right repair, not the quickest one.

Common DuraFlex Chimney Cleaning Problems We Solve in Ontario
Here’s what we actually find when we pull up to a DuraFlex system in Ontario:
- Rusted galvanized caps and spark arrestor screens. The postwar tract homes in 91761, 91762, and 91764 often still have their original DuraFlex terminations. Years of thermal cycling plus the fall Santa Ana winds loosen the screens and rust the galvanized metal. Once the screen fails, everything else follows.
- Wind-driven dust and thin flaky soot. Ontario homes burn decorative Duraflame logs a few times a year, not cordwood every night. That produces light, flaky creosote that’s easy to sweep but still needs to come out before first fire. Santa Ana dust adds grit that can clog a direct-vent run.
- Bird and animal nesting in damaged terminations. An uncapped or screen-damaged DuraFlex chimney is an open invitation. We pull nests out of flues on a steady basis in the fall, after the winds have carried debris into every opening.
- Stiff or warped damper and firebox hardware. Ontario summers hit triple digits. That heat bakes the metal on older DuraFlex factory-built units. Dampers stiffen, linkages warp, and the firebox seals fail even when the fireplace barely gets used.
- Debris-packed flue openings. Palm fronds, eucalyptus leaves, and dust ride the Santa Anas straight into uncapped or screen-damaged DuraFlex terminations. A packed flue opening causes backdrafting and smoke in the house the first time you light a fire.
DuraFlex Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s housing stock shapes this work in a very specific way. Most of the city’s single-story stucco tract homes went up between the 1950s and the 1980s, and the fireplaces in those houses are factory-built metal units, many with original DuraFlex chimney assemblies. Homeowners in 91762 and 91764 burn decorative logs a handful of times each year. What that means for the flue is a light coating of thin, flaky soot, not layered, glossy creosote. It still has to be swept before the season, but the real wear comes from the wind. After a fall Santa Ana event, our tech was called to a single-story stucco tract home near Euclid Avenue in 91762 where the original DuraFlex cap screen had rusted loose and the flue was packed with palm fronds and a bird nest. We also handle DuraFlex service in Montclair with the same attention to wind damage. We pulled the debris, ran a Level 2 inspection, swept the light soot from the flexible liner, and fitted a new screened termination cap. The homeowner was back to first fires before Thanksgiving. That call pattern is more typical than the winter wood-burning work you’d find in a mountain town.
So if your DuraFlex system in Ontario looks like it’s not drafting right, or you see debris in the cap, don’t assume the flue is fine because you barely use it. The wind and heat are doing the damage whether the fireplace is lit or not.
DuraFlex Models & Products We Service in Ontario
We service DuraFlex Direct-Temp direct-vent fireplace systems, DuraFlex DirectVent Pro venting, DuraFlex Galvanized flexible chimney liner kits, and DuraFlex factory-built fireplace chimney and cap assemblies. On cleaning visits, we’ll identify exactly which system you have, assess the condition of the flue and termination, and give you a straight answer about what needs repair. When we replace a cap or screen, we use OEM-spec parts where fit and listing matter. For liners and dampers, we match the part to your existing flue geometry, not the other way around. Stocking the common termination components means we can usually complete cap and screen work the same day we’re out for the sweep.

FAQs – DuraFlex Chimney Cleaning in Ontario
Yes. Decorative logs still produce soot and creosote, just thinner and flakier than cordwood. But the bigger issue in Ontario is wind-driven debris and bird nesting, which has nothing to do with how often you burn. An annual sweep and cap inspection is a fire-safety obligation, not an optional chore. Call (855) 382-6159 if yours hasn’t been checked this season.
Yes, it’s a real problem. A blocked termination causes backdrafting, which pushes smoke and carbon monoxide into the house. It also traps heat against the metal, which accelerates rust on the cap and screen. We clear packed debris on a regular basis during Ontario’s wind season, and we’ll fit a proper screened cap if the one you have has failed. Our crew also covers DuraFlex repair in Chino for similar wind-driven issues. Call us and we’ll get it cleared before your first fire.
Yes, we perform Level 2 camera inspections on DuraFlex direct-vent systems throughout Ontario, including 91761. A Level 2 inspection is the right call after a wind event, after a bird nest removal, or when a system hasn’t been used in years and you want to verify the flue is intact before lighting anything. The camera tells us what a visual inspection can’t see.
They do. Thermal cycling from triple-digit summers plus the sandblasting effect of Santa Ana winds weathers galvanized components faster than in coastal cities. We routinely see Ontario DuraFlex caps that look ten years older than they are. The fix is usually a new OEM-spec screened termination, which costs far less than the damage an uncapped flue invites. Call (855) 382-6159 for a condition check.
Leave the nest alone and call us. Don’t light a fire to drive them out, and don’t try to pull the nest yourself. We’ll remove the nesting and debris, inspect the flue for damage, sweep any soot that’s built up, and fit a proper screened cap so it doesn’t happen again. Bird nesting in DuraFlex terminations is a steady call in Ontario, especially in fall after the winds. The same pattern brings us calls for DuraFlex in San Antonio Heights. We handle it the same visit.
