Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Mentone, CA | Ashwood Chimney Sweep
We provide independent Gelco chimney cleaning and repair service across Mentone, and the reason our Gelco work here differs from a standard cleaning comes down to one thing: Mill Creek Canyon. Santa Ana winds push loose ash, charred leaf bits, and fine canyon sediment directly into caps and flues, which means a Gelco insert in Mentone often needs a cap-and-flue clearing even in months when the fireplace hasn’t been lit once. We carry OEM Gelco components and the cleaning tools sized for their narrower flues. Call (833) 805-3229 for a free estimate anywhere in the 92359 zip code.
Why Mentone Residents Choose Us for Gelco Service
We’ve swept and serviced Gelco fireplace inserts and wood-burning units across the San Bernardino foothills long enough to know their clamps, liners, and damper hardware by sight. Norm Castillo, our owner, grew up off Sierra Avenue in Fontana and trained at Chaffey College’s HVAC and building systems program before narrowing his focus entirely to chimneys and venting nearly two decades ago. That matters in Mentone because older ranch-style homes from the 1940s through the 1970s often hide retrofit surprises behind the surround. We treat every Gelco job as an independent repair: we diagnose the appliance in front of us, not what a manual says it should be doing. Our Gelco sales & service work runs on that same principle, whether it’s a cleaning, an inspection, or a liner repair.

Common Gelco Chimney Cleaning Problems We Solve in Mentone
- Loose or corroded liner seams and clamps. Gelco flexible liner kits on insert installs take years of canyon grit and ash cycling. Seams loosen, clamps corrode, and creosote bypasses the liner wall. We see this on older Mentone inserts retrofitted into masonry fireplaces, where the original flue was never sized for the insert.
- Packed upper flues on narrow insert liners. Gelco insert flues are narrow relative to open masonry fireplaces. Add Mill Creek Canyon sediment and ash from Santa Ana events, and the upper flue can pack tight enough to choke draft. A standard sweep clears the lower section; ours clears the full run.
- Warped top-sealing damper gaskets. Hot inland summers and dry wind swings in Mentone harden and warp the gasket material on Gelco-equipped top-sealing dampers. Smoke spills into the room because the seal no longer seats. We replace or reseat those gaskets regularly.
- Pitted glass-door and gasket assemblies. Burning debris and damp canyon wood produces acids and fly ash that pit glass and degrade gaskets. Gelco glass-door assemblies on Mentone fireplaces often show seal failure at the corners first. We clean, reseal, or replace glass as needed.
- Cap packed after wind events. After a Santa Ana blow, Gelco caps and flues in Mentone collect a distinct mix of loose ash, charred leaf fragments, and fine sediment from the canyon upstream. That cap plug gets misdiagnosed as a flue issue. It’s a local pattern we now check first.
Gelco Service in Mentone: What Local Conditions Mean for Your Equipment
Mentone sits at the mouth of Mill Creek Canyon in the San Bernardino foothills, and that geography writes the maintenance schedule for Gelco inserts here. Santa Ana winds drive ember-laden debris and ash into chimneys on a path that follows the canyon’s smoke route, not the winter heating calendar. A Gelco insert in a Mentone home can sit unused from April through October and still arrive at fall with a cap packed tight and a flue glazed with creosote from prior seasons. We’ve pulled caps packed so solid with sediment that the mesh looked like a solid plate. That’s why we tell Mentone homeowners to schedule a cap-and-flue check after major wind events, not just before the first cool night. The canyon dictates the cleaning schedule more than the thermostat does. For Gelco owners specifically, the narrow liner means that wind-driven sediment packs the upper flue faster than it would in an open masonry chimney, and the fix is a full flue sweep plus cap clearing. One job, one crew, one call.
Gelco Models & Products We Service in Mentone
We service Gelco wood-burning fireplace inserts, stainless flexible chimney liner kits, glass-door and screen assemblies, and damper components including top-sealing dampers. When a Gelco insert in Mentone needs liner clamps or damper hardware, we use OEM Gelco parts where the fit matters, because their liner and clamp tolerances don’t forgive generic substitutes. For gaskets, caps, and replacement glass, we use quality aftermarket components where OEM is unavailable or overpriced, and we tell you which is which. We stock common Gelco clamp and gasket sizes for faster turnaround across Mentone service area calls, so you’re not waiting on a shopful of parts for a straightforward repair. If your insert’s liner or firebox is sound, we repair and reseal. If the liner is crushed or the firebox is cracked through, we’ll tell you plainly that replacement is the safer call.

AfterGelco Service Pricing in Mentone
Gelco chimney cleaning in Mentone typically runs $149 to $250 for a standard sweep of an insert flue, and most jobs in the 92359 area are done in a single visit. If a Level 2 camera inspection is needed because the flue has been sitting or the home changed hands, that adds $100 to $200 depending on what we’re documenting. Cap replacement for wind-damaged or packed caps runs $60 to $180 depending on the cap size and whether flashing repair is needed. Top-sealing damper gaskets we usually replace or reseat during the cleaning visit. The final number depends on liner access, creosote loading, and whether the cap and damper need parts, not just cleaning. A free estimate pins it down. Call (833) 805-3229 and we’ll take a look.

FAQs – Gelco Chimney Cleaning in Mentone
Because wind-driven ash, charred leaf bits, and canyon sediment pack the cap and narrow insert flue, killing draft and letting smoke spill back into the room. A warped top-sealing damper gasket often makes it worse. We clear the cap, sweep the full flue, and reseat or replace the damper gasket. Call (833) 805-3229 and we’ll set it straight.
More often than the usual once-a-year advice. Mentone’s canyon winds deposit sediment and ash into caps and flues year-round, even when the fireplace sits idle, and Gelco insert flues are narrow enough that they pack faster than open masonry chimneys. We recommend a sweep before burning season and a cap-and-flue check after major Santa Ana events or nearby mountain fires. If you burn debris or damp canyon wood, or need Gelco service in Highland, sweep mid-season too. Call (833) 805-3229 and we’ll help you set a schedule that matches how you actually burn.
Usually yes. We can sweep, inspect, and resecure Gelco flexible liner clamps and seams from the firebox and cap access without removing the insert, as long as the liner isn’t crushed or disconnected mid-run. If camera inspection shows a crushed or separated liner, we’ll tell you plainly and quote the replacement. Call (833) 805-3229 and we’ll run a camera before recommending anything.
We do. We stock common cap sizes and use quality aftermarket caps where Gelco OEM isn’t required, and we repair flashing where wind has worked the cap loose. After Santa Ana events, we check the cap first because Mentone’s wind pattern clogs them faster than Gelco in Yucaipa or anywhere else we work. Call (833) 805-3229 for a cap check or replacement.
You’ll need to check your specific Gelco warranty terms, but an independent cleaning or repair by a qualified sweep typically doesn’t void standard coverage.

Call (833) 805-3229 and we’ll walk you through what to look for in your warranty paperwork.
