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 Running Springs, CA | Corona Chimney Sweep
DuraFlex chimney cleaning in Running Springs means pulling caps that have been hammered by snow load, rotary-cleaning liners glazed with creosote from long burn seasons, and clearing squirrel nests out of flues in cabins that sat empty since spring. We’re an independent DuraFlex service provider working across the 92382 zip code, and the thing that sets our work apart here is that we know what second-home neglect plus 6,000 feet of elevation actually does to a stainless liner. Call (855) 382-6159 to schedule a cleaning or inspection before the next freeze.
Why Running Springs Residents Choose Us for DuraFlex Service
We’ve spent years cleaning and repairing DuraFlex chimney systems across the San Bernardino Mountains — including DuraFlex service in Lake Arrowhead — so we know how their stainless liners, caps, and components actually age under snow load and heavy wood-burning cycles. As an independent company we diagnose what your DuraFlex system needs rather than selling a brand-approved script. If the liner is sound, we clean it and tell you so. If the seams are separating or the cap is crushed, we show you the problem and repair it in-house. That’s the difference between a sweep crew and a full-service chimney company.
Nolan Ferris runs our operation, and he’s the one walking Running Springs rooftops checking cap fit and liner condition. He grew up in South Corona and put in over a decade inspecting and cleaning flues across the Inland Empire before focusing on mountain properties like the ones up here. That experience matters when you’re dealing with a DuraFlex system in a 1960s cabin with a steep roof and a cap that’s taken three winters of pine branch hits.
We’re a DuraFlex sales & service provider, which means we stock the components that actually fail in this climate. Caps, top plates, liner sections, connectors. No waiting on a parts order when the snow’s coming and your stove is your heat source.

Common DuraFlex Chimney Cleaning Problems We Solve in Running Springs
- Flexible liner seam separation from thermal cycling. DuraFlex SW and Pro liners handle heat well, but in Running Springs the temperature swing from a hot fire to a freezing night puts real stress on the seam lock. After enough seasons of steady wood-stove use, those seams can loosen and let flue gas leak into the chase. We check every liner seam during cleaning and resecure or replace sections where needed.
- Snow-crushed caps and top plates. Heavy snow load is the big one up here. DuraFlex stainless caps are strong, but a wet storm followed by a hard freeze can bend or tear a cap right off the flue. The same goes for top plates. Once the cap’s gone, rain and pine needles go straight down the liner. We replace damaged DuraFlex caps with new stainless units sized to the flue, not whatever generic cap happens to be on the truck.
- Glazed creosote inside DuraFlex liners. Cabins burned hot and slow through long mountain winters build creosote differently than weekend fireplaces. It hardens into a glassy glaze that a standard brush won’t touch. We use rotary cleaning with stainless whip heads to break that glaze down to bare metal without damaging the DuraFlex liner wall. This matters because glazed creosote is the fuel for a chimney fire.
- Corrosion at the liner-to-cap connection. Meltwater refreezes in fall and spring temperature swings, and the liner-to-cap connection takes the brunt of it. We see pitting and corrosion there on older Running Springs systems. If the connection is compromised, we replace the cap and connector before water works its way further down the liner.
- Wildlife blockage in second-home flues. This is the Running Springs special. Squirrels, birds, pine needles, and the occasional pine cone end up in chimneys on cabins that sat closed for months. We’ve pulled enough nesting material out of DuraFlex liners to know that clearing wildlife blockage is the first priority on a reopened cabin, not creosote scraping.
DuraFlex Service in Running Springs: What Local Conditions Mean for Your Equipment
Here’s something specific to Running Springs that most chimney people don’t factor in: because many cabins and vacation homes sit empty for months at a time, DuraFlex liners in second homes often collect squirrel nests and pine debris over the off-season. Our first cleaning on a reopened cabin is as much about clearing wildlife blockage as scraping creosote. We were called to a chalet in the Arrowbear area of Running Springs where the homeowner’s DuraFlex-lined wood stove had been drawing poorly all winter. Pulling the cap, we found it dented and half-packed with squirrel nesting and pine needles, and the liner interior glazed with hard creosote. We replaced the crushed cap with a new stainless multi-flue cap, rotary-cleaned the DuraFlex liner down to bare metal, and the stove drafted correctly again with the chimney safe for the rest of the heating season. That’s the kind of job that’s ordinary up here but would sound unusual to a chimney company working flatland homes in Corona.
If you own a Running Springs property that sits empty between visits, the off-season isn’t downtime for your chimney. It’s when the damage and blockage happens. We recommend a Level 2 inspection before you light anything after a long absence.
DuraFlex Models & Products We Service in Running Springs
We work on the full DuraFlex product range installed in Running Springs homes and nearby mountain communities: DuraFlex SW stainless steel flexible chimney liner kits, DuraFlex Pro flexible relining systems, and DuraFlex repair in Crestline and surrounding areas for multi-flue and custom chimney caps, including premium stainless rain caps and top plates. Older cabins retrofitted with wood stoves usually have SW liners; newer installs and relines often use Pro systems. Either way, we know the liner diameters, connector types, and cap configurations that show up in mountain construction.
On parts, our approach is straightforward. We fit genuine DuraFlex components for liners and caps wherever the original system is still serviceable. When the correct OEM piece isn’t practical to source quickly, we use quality UL-listed aftermarket parts and tell you why. We recommend repair when the liner and cap are sound, and rebuild only when corrosion or cracked flue joints make the system unsafe. No upselling, no fear-pitching.

AfterDuraFlex Service Pricing in Running Springs
DuraFlex chimney cleaning services in Running Springs vary depending on what we find when we get on the roof and into the flue. A standard cleaning and inspection runs differently than a cleaning that includes cap replacement or liner repair. The honest answer is that the flatland pricing you might see online doesn’t apply up here. Steep roofs, snow access issues, wildlife blockage, and glazed creosote all factor into the job time.
A free estimate includes what it always includes with us: we look at the system, we show you what’s going on, and we quote the work before anything gets done. No work starts without you seeing the problem and approving the fix. Call (855) 382-6159 for an exact quote based on your Running Springs property.

FAQs – DuraFlex Chimney Cleaning in Running Springs
Yes. Many older Running Springs cabins built between the 1940s and 1970s had wood stoves or inserts added later, usually with a DuraFlex SW or Pro flexible liner. We clean, inspect, and repair those liners on a regular basis. If the seams are intact and the liner wall is structurally sound, a cleaning and inspection is all you need. If the liner is compromised, we’ll show you exactly what we found and walk through repair or replacement options. Call (855) 382-6159 to schedule a look.
Snow load and falling pine branches. Running Springs sits at 6,000+ feet, and the heavy wet snow that piles up on steep-pitched roofs slides right onto chimney caps and top plates. A DuraFlex cap can only handle so much weight before it bends or tears. Pine branches from the trees around your cabin add another hit. We replace damaged caps with new stainless units and, where the roofline allows, adjust the install to reduce future impact. If your cap looks crushed or missing, don’t wait until you light the stove to address it. Call (855) 382-6159.
Yes, and this is the single best decision you can make for a second home in Running Springs. Empty flues collect squirrel nests, pine needles, and debris. Dampers rust. Caps get hit by falling branches. A Level 2 inspection uses a camera to check the full interior of the DuraFlex liner and the connections at the cap and appliance. We’ve caught wildlife blockage, broken seams, and corrosion before they became chimney fires or carbon monoxide problems. If you can’t see daylight through the damper, we need to talk before you light that first fire of the season.
At least once per burning season, and more often if the stove is your primary or backup heat source. Running Springs’ long, cold winters mean extended burn seasons and more creosote accumulation than you’d see at lower elevation. Wood stoves running continuously build glazed creosote quickly, especially if the fire is burned slow and low. If you burn through cords of wood each winter, schedule a cleaning in the fall and have us check again mid-season. Call (855) 382-6159 to set up a seasonal schedule.
Yes. Crown and flashing repair is part of our core chimney repair service, not a job we refer out. A crumbling mortar crown lets water get between the flue and the chase, which accelerates corrosion on the liner and cap. We repair or recast crowns, replace worn flashing, and make sure the connection between the masonry and the DuraFlex liner is sealed correctly. Same crew, same visit. No handoff, no waiting on a third party. Call (855) 382-6159 and we’ll get eyes on it.
