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 | Pilgrim Chimney
We provide independent Running Springs Chimney Sweep and DuraFlex service across the area, and the one thing that sets our work apart here is simple: we know exactly what 6,000 feet of elevation, heavy snow, and resinous pine smoke does to a DuraFlex liner and cap. Pilgrim Chimney has been servicing DuraFlex systems in this mountain community long enough to predict where they fail before we even set up the ladder. If your DuraFlex chimney needs a sweep, a cap replacement, or a straight answer about whether that liner can be saved, call us at (866) 253-5031.
We also handle DuraFlex sales & service across the broader mountain region, so parts and familiarity are never a problem.
Why Running Springs Residents Choose Us for DuraFlex Service
Most chimney companies in the San Bernardino Mountains can run a brush up a flue. Far fewer can tell you whether the creosote glaze inside your DuraFlex liner is normal for a cabin burning pine, or whether that crushed cap you found after the last storm is worth repairing. Len Pacheco, our owner, has spent the better part of three decades working chimneys across the High Desert and mountain communities. He grew up in Spring Valley Lake, trained in building trades at Victor Valley College, and got into this line of work after helping his father deal with a creosote fire that got closer than anyone wanted. That’s the kind of experience that makes a difference when you’re standing in a Running Springs cabin with a flue that hasn’t been touched since the Reagan administration.
We stock DuraFlex-compatible components, diagnose by part rather than by guess, and we don’t recommend work you don’t need. For homeowners across Running Springs service area, that means one call handles the sweep, the inspection, and whatever repair the mountain has made necessary.

Common DuraFlex Chimney Cleaning Problems We Solve in Running Springs
These are the issues we see most often when we’re called out to Running Springs homes. Each one ties directly to what this mountain environment does to a chimney system.
- Crushed or dislodged DuraFlex caps and spark arrestors. Snow load and falling pine branches are brutal on chimney caps up here. After a heavy winter, we routinely find multi-flue caps dented inward or knocked askew, leaving the flue open to rain, animals, and ember escape. A healthy cap isn’t optional in Running Springs, especially with summer wildfire risk.
- Accelerated creosote glaze inside DuraFlex liners. Pine and cedar burn hot but they also produce resinous smoke that condenses into a hard, shiny glaze on liner walls. In older Running Springs cabins with undersized flues, that glaze builds faster than the manufacturer’s baseline cleaning schedule accounts for. Annual sweeping becomes a hard requirement, not a suggestion.
- Cracked crowns and compromised top plates from freeze-thaw cycles. Water gets into hairline cracks, freezes, expands, and widens the damage. Repeat that a few hundred times over a mountain winter and you’ve got water intrusion around the top plate of an otherwise sound DuraFlex system. We see this constantly in homes built from the 1920s through the 1970s.
- Pinhole corrosion or crushed liner sections at offsets. Older DuraFlex flexible liners sometimes develop pinhole corrosion or get pinched where they bend around an offset. That reduces draft and gives creosote a place to collect. It’s a quiet problem until the smoke starts backing up into the living room.
- Debris-packed flues after storms. A cap that’s been knocked loose by falling branches lets pine needles, twigs, and snow pour into the flue. We’ve swept liners that were a third full of pine duff, with glazed creosote underneath. That combination is a chimney fire waiting for a cold night.
DuraFlex Service in Running Springs: What Local Conditions Mean for Your Equipment
Running Springs sits at just over 6,000 feet under a dense pine and cedar canopy, and that single fact shapes every DuraFlex repair in Crestline and service we do here. After a heavy snow, chimney caps and spark arrestors are frequently crushed or dislodged by snow load and falling branches, which means spring cleanings in this town routinely turn into cap repairs. It’s not uncommon for a homeowner to call us for a standard sweep and learn that their DuraFlex multi-flue cap has been flattened since February. We’ve also found that many of the older cabins here, especially those built mid-century, have flues that are a size too small for the fireplaces they serve, which accelerates creosote buildup and puts extra strain on liner joints. When you combine undersized flues with resinous softwood smoke and freeze-thaw cycles at elevation, you get a set of conditions no generic chimney service page ever mentions. Here, it’s the difference between a chimney that works for another season and one that fails the first cold night you really need it.
A clean chimney isn’t exciting, until you remember what the alternative looks like.
DuraFlex Models & Products We Service in Running Springs
We work on the full DuraFlex line you’re likely to find in a Running Springs home. That includes the DuraFlex Stainless Steel Flexible Chimney Liner, the DuraFlex Insulated Flexible Liner Kit, DuraFlex Multi-Flue Caps, and DuraFlex Deluxe Rain Caps. For caps, top plates, and liner couplings, we use OEM DuraFlex components so the fit and rated performance are preserved. For standard wear items where OEM isn’t available, we use quality aftermarket stainless rather than whatever’s on the shelf at a hardware store. It’s the same parts-and-fix approach we bring to DuraFlex service in Muscoy, and it keeps turnaround fast when a storm has already done the damage and the next burn is a night away.

FAQs – DuraFlex Chimney Cleaning in Running Springs
Every year, without exception. Homes here burn pine and cedar, which produce resinous creosote that glazes over faster than the hardwoods most sweep schedules are based on. Add an undersized flue in an older cabin and you’re looking at buildup that justifies twice-a-year attention in heavy-use years. If you’re burning daily from October through April, call (866) 253-5031 before the first snow and we’ll get the flue ready for the season.
Most crushed or dislodged DuraFlex caps need replacement, not repair. The flanges and mesh rarely bend back into a functional shape after two feet of snow has sat on them, and a dented cap won’t seat properly against the top plate. We keep DuraFlex Deluxe Rain Caps and multi-flue caps in stock for Mentone DuraFlex service and Running Springs calls, so replacement is usually a single-visit job. Call (866) 253-5031 for a free estimate.
Yes. After any chimney fire, or if a major storm has visibly damaged your cap or crown, a Level 2 inspection is the only way to know whether the liner is still intact. We’ll run a camera down the flue and show you exactly what we’re seeing. Creosote glaze, pinhole corrosion, crushed sections at offsets. It’s all visible and we don’t recommend a single repair without photographic evidence you can see yourself.
It usually comes down to three things: the size of the flue relative to your fireplace, how much resinous softwood you burn, and whether your cap is still keeping debris out. Many older cabins in Running Springs have flues that were undersized from the day they were installed. That means the same amount of burning produces a thicker creosote deposit, faster. If your neighbor’s flue is properly matched to their appliance and yours isn’t, the difference shows up within one season. Call (866) 253-5031 and we’ll take a look and tell you exactly what’s going on.
We can. Gas inserts vent through the same DuraFlex liner and cap components, and they need the same kind of attention to the vent path, cap integrity, and water management. The buildup risk is different, less creosote and more corrosion from acidic condensate, but the inspection and cleaning discipline is the same. We service both types across Running Springs.
