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 | Ashwood Chimney Sweep
We provide independent DuraFlex chimney cleaning and service across Running Springs, and the thing that makes our work here different is simple: we actually know what 6,000 feet of altitude does to a DuraFlex liner. Resinous pine and fir creosote, freeze-thaw corrosion, and vacant cabins that sit empty all summer create problems no lowland sweep sees. We’re not authorized or endorsed by DuraFlex, but we’ve serviced their systems in these mountains long enough to know every failure point. Call Norm Castillo at (833) 805-3229 and we’ll scope the flue before you light the first fire.
Why Running Springs Residents Choose Us for DuraFlex Service
Most chimney companies in the San Bernardino Mountains can sweep a flue. Fewer know what happens when a DuraFlex SS liner has been running hard through a January cold snap, or why a DuraFlex cap screen corrodes faster at this elevation than it does in Redlands. We do. We’ve worked on DuraFlex factory-built systems, flexible stainless liners, direct-vent gas venting, and caps across Running Springs long enough to spot problems before they become chimney fires or carbon monoxide calls. Norm Castillo, our owner, grew up off Sierra Avenue in Fontana and trained through the HVAC and building systems program at Chaffey College in Rancho Cucamonga before narrowing his focus to flues and venting. He’s been at this close to two decades. We don’t use bargain-bin parts and we don’t cut corners on mountain chimneys, because winter up here doesn’t forgive shortcuts. DuraFlex sales & service is one of our core specialties, and we stock OEM components locally so Running Springs customers aren’t waiting on a shipment while their chimney sits unusable.

Common DuraFlex Chimney Cleaning Problems We Solve in Running Springs
- Glazed creosote cracking liner joints. Running Springs burns a lot of pine and fir, and those resinous woods produce creosote that bakes hard and glossy inside a DuraFlex flexible liner. After a long October-through-April burn season, that glaze can crack the liner joints, especially where the liner wasn’t sized properly for the stove. We see this most often in older cabins with liners installed decades ago.
- Corroded cap screens and top plates. The freeze-thaw cycle at 6,000 feet is brutal on metal. Snow melts into the cap screen during the day, refreezes at night, and after a few seasons the screen and top-plate fasteners corrode through. Then snowmelt drips into the flue, and you’ve got rust streaks down the firebox wall.
- Nesting in vacant second-home chimneys. Running Springs has a lot of cabins that sit empty from May through September. Birds and squirrels find their way past a damaged DuraFlex cap and build nests that block the flue entirely. The owner comes back in October, lights a fire, and the smoke has nowhere to go but the living room.
- Undersized liners in older A-frames. Many of the 1960s and 1970s A-frames around Running Springs originally had small or unlined flues. When a modern wood insert goes in, the existing DuraFlex liner is often too narrow for the appliance, which causes downdraft and poor draft performance. Cleaning helps, but relining is usually the real fix.
- Downdraft on cold mornings. At this elevation, cold air sinks into the flue overnight. If the DuraFlex liner has creosote buildup or a partially blocked cap, that cold-air column pushes smoke back into the house when you try to light a fire on a 15-degree morning. A clean liner and clear cap solve it more often than people expect.
DuraFlex Service in Running Springs: What Local Conditions Mean for Your Equipment
Running Springs sits at 6,000-plus feet, and the first hard cold snap often arrives while second-home owners are still down the hill. That timing is the single biggest difference between chimney work here and in the flatlands. A lowland sweep doesn’t plan a fall schedule around thousands of vacant cabins coming back online the same week. We do. Every October we scope vacant Running Springs chimneys before the burn season starts, because a DuraFlex cap that was fine in May might be packed with squirrel nest by September. Last October we got a call from a homeowner on a chalet-style street off Highway 18 whose DuraFlex-capped flue had been unused all summer. Our tech scoped it and pulled out a squirrel nest wedged against the cap screen, then found glazed pine creosote in the liner joints from the previous winter. We swept the flue, replaced the damaged cap screen with an OEM DuraFlex multi-flue cap, and the fireplace drafted cleanly on the first test burn. That’s the kind of mountain-specific work a generic DuraFlex page never prepares you for. This is our Running Springs service area, and we’ve learned to schedule around the mountain’s calendar, not a flatland one.
DuraFlex Models & Products We Service in Running Springs
We service the full range of DuraFlex product lines found in Running Springs homes: DuraFlex SS flexible stainless liner kits, DuraFlex Pro factory-built chimney systems, DuraFlex direct-vent and gas fireplace venting, and DuraFlex caps and top plates. When a part needs replacing, we stock OEM DuraFlex liners, caps, and top plates for exact-fit installation. We’ll use a quality aftermarket damper or screen only when it meets the same specs as the DuraFlex original. If a liner is cracked, corroded, or undersized for the appliance, we recommend relining or replacement. Patching a liner joint and calling it done isn’t a mountain fix. It’s a bet against January, and January up here always wins.

FAQs – DuraFlex Chimney Cleaning in Running Springs
Cold air columns settle into the flue overnight at this elevation, and if your liner has creosote buildup or a partially blocked cap, that cold air pushes smoke back into the house when you light a fire. The fix is usually a thorough sweep and cap inspection, not a rebuild. If it’s been more than a year, call (833) 805-3229 and we’ll scope it before your next cold morning.
Once a year, minimum, even if the cabin only sees weekend use from October through April. Pine and fir creosote builds fast, and a cabin that sits cold all week develops condensation inside the liner that makes creosote stick worse. If the cabin has been vacant all summer, the pre-season scope is non-negotiable, because nesting debris can turn your first fire into a smoke-filled room.
You can absolutely replace just the cap. We keep OEM DuraFlex caps and top plates in stock for Running Springs jobs because cap corrosion is one of the most common problems we see. We’ll scope the liner while we’re up there to make sure the cap is actually the only issue. Call (833) 805-3229 and we’ll get it done before the next snow.
It can be. An undersized liner restricts draft, which means smoke and carbon monoxide have a harder time leaving the house, and creosote accumulates faster in a narrow flue. We see this constantly in older Running Springs A-frames where a wood insert was added to a chimney built decades ago. We’ll scope it and tell you whether relining is necessary or whether the current setup is safe to run. Get the straight answer at (833) 805-3229.
We do. DuraFlex direct-vent and gas fireplace venting is part of our regular service scope in Running Springs, and gas systems have their own failure modes at this altitude: condensation, corroded termination caps, and blocked vent runs from nesting wildlife. Gas doesn’t produce creosote, but it produces carbon monoxide, and a blocked vent is a carbon monoxide problem. If your gas fireplace hasn’t been inspected, call (833) 805-3229.
