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 Montclair, CA | Corona Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and repair throughout Montclair’s 91763 corridor. What makes our DuraFlex work different here comes down to the housing stock: most Montclair fireplaces from the 1950s through 1970s were built with clay tile flues and no modern liner, so a DuraFlex call rarely ends at just a sweep. We run the camera, show you what’s actually happening inside that flue, and repair what we find, whether that’s a reseal, a cap replacement, or a full relining conversation. Call (855) 382-6159 for a free estimate.
Why Montclair Residents Choose Us for DuraFlex Service
We’ve worked DuraFlex chimney products across the 91763 corridor for years, from their stainless flex relining kits to their caps and top plates, so we know how their components hold up in mid-century Montclair masonry chimneys. That matters because DuraFlex liners behave differently depending on what surrounds them. In a Montclair tract home with original clay tile, the liner isn’t just sitting in a chimney. It’s sitting against spalled clay and mortar joints that have been deteriorating since the Eisenhower administration. We know what that does to a liner over time because we’ve pulled and inspected enough of them to see the pattern.
As an independent sweep, we diagnose and repair what’s actually failing rather than pushing a brand-authorized replacement script. Nolan Ferris started this company after years of inspecting and cleaning flues across the Inland Empire, and his approach hasn’t changed: he shows homeowners exactly what stage of creosote buildup they’re dealing with and what it means for draft and fire risk. That’s the difference between a company that brushes and bills, and one that tells you whether your DuraFlex setup is still safe to run. We service what we find, and we sell DuraFlex sales & service parts when they’re genuinely needed, not because a script says so.

Common DuraFlex Chimney Cleaning Problems We Solve in Montclair
- Spalled clay pinching the liner. DuraFlex stainless liners get installed into Montclair’s original clay tile flues, but the clay itself is decades old. When it spalls and the mortar joints crumble, those fragments can rest against the flex liner and abrade it over heating cycles. We see this often enough in 91763 homes that we check for it on every cleaning call before we touch a brush.
- Santa Ana downdraft blowback through the cap connection. After a wind event rolls through the Pomona Valley, soot-stained fireplace faces and smoky-smelling living rooms spike across Montclair. The downdraft pushes creosote and ash back through older dampers and past DuraFlex cap connections that no longer seal tight. We reseal or replace the cap and top plate, then address the creosote the wind pushed down.
- Condensate pitting at the liner’s bottom section. Montclair’s hot inland summers and cool winters create temperature swings that collect condensation above the damper. Over time, that moisture sits at the lowest point of a DuraFlex liner and starts pitting the stainless. It’s slow, but it’s visible on camera, and it’s exactly the kind of thing a Level 2 inspection catches before it becomes a draft problem.
- Undersized retrofits causing smoke rollout. We’ve walked into Montclair homes where a DuraFlex component was retrofitted into an original masonry firebox without a proper sizing check. The result is smoke rolling back into the living room because the liner diameter doesn’t match the firebox opening. That’s a fixable problem, but only if someone actually measures and inspects instead of swapping parts blindly.
- Creosote buildup inside serviced liners. A stainless liner doesn’t eliminate creosote. It changes how it accumulates. In Montclair, where fireplace use runs November through February, stage-two creosote can build inside a DuraFlex liner that hasn’t been swept in a few seasons. We classify what we find and show you, so you know whether it’s a routine sweep or something that needs more attention.
DuraFlex Service in Montclair: What Local Conditions Mean for Your Equipment
Here’s the pattern we see across Montclair that you won’t find in cities with newer housing stock. The 91763 tract homes were built with original brick fireplaces and clay tile flues but no modern liner. That means a routine DuraFlex cleaning call here almost always expands into a Level 2 camera inspection and a relining conversation. The clay tiles are spalling. The mortar joints are deteriorating. The flex liner, if there is one, may be doing its job, but it’s doing it inside a chimney that was never designed for what we’re asking it to do now. In a neighboring city with 1990s construction, a sweep is just a sweep. In Montclair, the housing stock itself drives the conversation toward inspection and repair. We don’t push relining unless the camera shows us a reason, but in this city, the camera usually does.
That’s also why we stock DuraFlex OEM liners, caps, and top plates for fast Montclair turnaround. When a homeowner near the Pomona Valley foothills calls after a wind event, we don’t want to tell them their cap is shot and then wait two weeks for parts. See our Montclair service area page for full coverage details.
DuraFlex Models & Products We Service in Montclair
We service the full line of DuraFlex products found in Montclair homes, including the Stainless Steel Flexible Chimney Liner Kit in round 6-inch, the Pro Flex Relining Kit, the Chimney Cap and Multi-Flue Cap line, and the Insulated Flex Liner for wood and insert applications. When a part needs replacing, we use genuine DuraFlex OEM components for liners, caps, and top plates where fitment and warranty integrity matter. For non-critical hardware like brackets and fasteners, we use quality aftermarket parts. We’ll also tell you plainly when a liner is still serviceable versus when the surrounding clay tile and firebox demand relining or rebuild before any new part makes sense.

FAQs – DuraFlex Chimney Cleaning in Montclair
The smell comes from downdraft. Santa Ana winds push air down your flue, and if your DuraFlex cap and top plate no longer seal tight against the original clay tile, creosote and ash get blown back through the damper and into the living room. The fix is usually a reseal or cap replacement, plus a sweep to remove what the wind pushed down. Call (855) 382-6159 and we’ll run a camera up there to see exactly what’s failing.
Yes. DuraFlex flexible liners are designed for exactly this situation. We can run a stainless flex liner through an original clay tile flue without tearing out masonry, as long as the firebox and chimney structure are still sound. That’s what the Level 2 inspection is for. We’ll show you the camera footage so you know what we’re working with. Call (855) 382-6159 to schedule an inspection before your next burning season.
Once a year if you burn wood regularly through the November-to-February season. Montclair’s cool winters drive consistent fireplace use, and even a stainless liner accumulates creosote. If you burn mostly gas, every two years is usually fine. We’ll classify what we find and tell you if your schedule needs to change.
We do both. We clean caps as part of a sweep, and we replace them when the cap, top plate, or seal no longer holds. After a Santa Ana event, we tend to see a wave of cap replacements across Montclair. We stock DuraFlex OEM caps locally for faster turnaround. Call (855) 382-6159 for a free estimate if you suspect your cap isn’t sealing.
No. We’re an independent chimney service company. We buy DuraFlex products through the same contractor supply channels other professional sweeps use, and we install and service them daily. We are not manufacturer-affiliated or authorized by DuraFlex, which means we have no incentive to sell you a DuraFlex part when an honest repair would serve you better. We repair what we find, and we use DuraFlex components when they’re the right fit for the job.
