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 Mentone, CA | Oakridge Chimney Sweep
We clean, inspect, and repair DuraFlex chimney systems throughout Mentone, CA, and we’ve seen how this canyon corridor treats stainless liners differently than anywhere else. The short version: most DuraFlex chimneys in Mentone need more than a basic sweep because softwood scrap burns hot and leaves a glazed creosote that light brushing won’t remove. If you’re seeing weak draft, smoke backing into the room, or a cap that’s packed with ash, call us at (866) 563-3051 and we’ll tell you what’s actually going on.
Why Mentone Residents Choose Us for DuraFlex Service
Walt Drennan has been working chimneys for going on eighteen years, and he still knows most of his regulars by the layout of their fireboxes. Our crew handles DuraFlex systems every week across the Mentone foothills, from factory-built inserts to replacement liners dropped into older masonry chases, and we offer DuraFlex service in Calimesa as well. That repetition matters. You learn what a DuraFlex flex liner sounds like when the whip hits glazed creosote versus dry ash, and you learn which cap designs hold up to Santa Ana dust and which ones clog by February.
We’re an independent shop. We buy DuraFlex-compatible components where they match the existing system’s dimensions and listing, and we tell you plainly when a liner is past saving. No manufacturer affiliation, no authorization implied, no incentive to push a replacement instead of a repair. DuraFlex sales & service is what we do, but the honest assessment comes first.

Common DuraFlex Chimney Cleaning Problems We Solve in Mentone
- Glazed creosote caked on flex liner walls. Locally cut softwood and scrap burned on canyon-edge lots produces a tar-like deposit that hardens into a shiny glaze inside DuraFlex liners. A standard wire brush skates right over it. We use rotary tools and chemical treatment to break it down, which is the difference between a clean flue and a chimney fire waiting for the next red-flag night.
- Top-mount caps and ember screens choked with ash. Santa Ana winds push dust, ash, and fine debris into caps across Mentone. By mid-season, we regularly find ember screens so packed the fireplace won’t draft at all. The fix is removal, cleaning, and often a cap replacement if the mesh has corroded from repeated heat and wind loading.
- Shifted adapters and thin spots where an insert liner meets the masonry chase. Older DuraFlex insert liners dropped into 1950s brick chimneys move and settle. We check the top plate and adapter connections on every visit because a gap there lets heat and gases into the chase, and that’s a problem no amount of sweeping solves.
- Water intrusion at the cap/crown interface. Exposed foothill roofs take weather head-on. When the crown cracks and the cap rusts, the topmost stainless sections of a DuraFlex liner begin to degrade. We catch this during cleaning before it turns into a full liner replacement.
- Clearance issues on newer manufactured fireplaces. Mentone has plenty of newer builds with factory-installed DuraFlex venting. Clearance checks matter here because the same canyon wind that pushes embers also shifts framing and insulation over time. We verify clearances as part of every service.
DuraFlex Service in Mentone: What Local Conditions Mean for Your Equipment
Mentone sits at the foot of the San Bernardino Mountains in a high-fire-hazard canyon corridor, and that location changes what your DuraFlex chimney needs. The mix of older rural ranch homes with masonry fireplaces and newer builds with factory-built inserts means we’re often working on a 1950s brick-and-mortar flue at one stop and a modern metal chimney two doors down the same afternoon. But the shared factor on canyon-edge and foothill lots is fuel. Homeowners here burn a lot of locally cut softwood and scrap, which produces creosote faster and denser than the seasoned hardwood typical in tract neighborhoods. In a DuraFlex liner that means glaze, not ash. Light sweeping won’t touch it. You need rotary or chemical treatment, and you need a cap and ember screen that actually breathe under Santa Ana conditions. That’s the Mentone difference, and it’s why a checklist sweep from a general contractor usually leaves the real problem untouched.
DuraFlex Models & Products We Service in Mentone
We service the full DuraFlex range, including DuraFlex Pro stainless flex liner kits, single-wall and insulated flex liner systems, round and square top-mount caps, multi-flue caps, and factory-built fireplace insert liners and components. When a part needs replacing, we use DuraFlex-compatible OEM or quality aftermarket liners, caps, and adapters that match your existing system’s dimensions and listing. We stock common cap sizes, ember screens, and adapter fittings for faster turnaround across the 92359 area, so you’re not waiting on a parts order while the burn season slips by. And if a liner is glazed out or corroded inside a failing chase, we’ll say so. Patching a liner that’s done is not a service we sell.

AfterDuraFlex Service Pricing in Mentone
Most DuraFlex chimney cleanings in Mentone run between $180 and $340 depending on the liner type, the amount of glazed creosote, and whether the cap and ember screen need work. Rotary or chemical treatment for heavy glaze adds labor, and cap replacement is quoted separately based on the size and style of your current setup. A Level 2 Inspection, which we recommend for any DuraFlex insert that hasn’t been examined in years, runs higher because it’s a full internal camera assessment, not a visual glance. Every estimate is free and includes a straight answer about what needs doing now versus what can wait. Call (866) 563-3051 and we’ll give you a number before any work begins.

FAQs – DuraFlex Chimney Cleaning in Mentone
No. A standard wire brush sweep will not remove glazed creosote from a DuraFlex flex liner, and that’s exactly the situation we see on Mentone canyon-edge lots where scrap and softwood burns are common. Glaze requires rotary equipment or chemical treatment to break the hardened surface before sweeping. We do both. If you’ve had a sweep done recently and the draft is still weak, chances are the glaze was left behind. Call (866) 563-3051 for an exact assessment.
Possibly. Standard ember screens clog fast in Mentone because Santa Ana winds carry fine dust and ash that pack the mesh. If your cap is original and the mesh is fine-woven, it will choke draft exactly when you need the fireplace venting right. We recommend coarser mesh where local fire codes allow, and we check the cap at every cleaning.
Because a basic sweep only clears what’s in the flue path. A Level 2 Inspection uses a camera to check the liner walls, adapter connections, and clearances inside the chase, which is where DuraFlex insert liners develop thin spots and shifted sections you can’t see from the top. In Mentone’s older masonry chimneys, that internal check matters, just as it does for our Loma Linda DuraFlex service customers. Walt’s been working these chimneys long enough to know what gets missed, and he’d want someone to do the same thorough job for his own family.
Watch for smoke backing into the room on windy days, a metallic rattling sound when the fire gets hot, or water staining near the crown. These often point to a shifted adapter, a thin section, or a compromised top plate. We find these on Mentone’s mid-century ranch homes regularly. The liner itself may still be sound. The connections around it often aren’t. A camera inspection gives you the answer without guessing.
Yes. We replace corroded DuraFlex caps with matching OEM or quality aftermarket units, and we address the crown interface so water stops getting into the chase. On exposed foothill roofs, the cap and crown work as a pair. If one fails, the other follows. Call (866) 563-3051 and we’ll quote the cap and crown work together, not as two disconnected jobs.
