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 | Glendale Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Running Springs, and the work here is different from any lowland market. At 6,000 feet, pine and cedar burn for months on end, glazing creosote to a tar-like hardness that a standard sweep won’t remove. If you own a DuraFlex liner or prefab system in the 92382 zip, call (833) 467-6493 for a free estimate from a crew that knows these exact failures.
We’re Glendale Chimney Sweep. Noel Tarkanian started this company because he saw too many sweeps that clean the easy stuff and walk past the problems. That doesn’t work on a DuraFlex service in Highland and other mountain towns that sees real snow load every winter.
Why Running Springs Residents Choose Us for DuraFlex Service
Most chimney companies in the San Bernardino Mountains will sweep a DuraFlex liner. Few can tell you which alloy it is, whether your top plate still seats correctly, or if that joint separation you noticed is a repair or a replacement. We can, because we stock and work with DuraFlex sales & service parts every week.
Noel grew up in the Montrose neighborhood of Glendale, where his family’s 1950s craftsman had a fireplace that needed attention every single winter. That’s where his interest in how chimneys actually work started. He picked up the trade through the HVAC and sheet metal program at Glendale Community College before moving into chimney work full-time, drawn to the diagnostic side of the job. A clean chimney isn’t a luxury – it’s just basic fire safety. That’s how we approach every Running Springs job.
We’re an independent service provider, not a DuraFlex authorized dealer. That independence means we give you the straight answer on repair versus replace, even when the straight answer is that you don’t need the bigger job.

Common DuraFlex Chimney Cleaning Problems We Solve in Running Springs
- Glazed pine creosote baked onto the liner interior. Long, slow-burning fires from pine and cedar don’t fully draft at 6,000 feet. The creosote settles and hardens into a tar-like glaze that a basic wire brush skims over. We use rotary cleaning with carbide-tipped attachments to get back to bare metal.
- Crushed caps and torn spark screens from snow load. After a heavy Running Springs winter, snow and ice can pile up on a DuraFlex top-mount cap and fold it inward. A torn screen or bent cap leaves the termination open to water and downdraft, which makes the next season’s fires draft poorly and smoke out the living room.
- Liner joints and top-plate collars pulling apart. Freeze-thaw cycles at this elevation stress every metal connection on the flue. We regularly find top plates that have lifted off the crown and couplings that have worked loose. Left alone, exhaust gases leak into the chase.
- Corrosion and pinhole pitting in lower-grade stainless. Cold, damp air and condensate sit inside the flue during the sub-freezing months. On older DuraFlex systems with 304 alloy instead of 316L, that means pitting where the liner has been exposed to moisture for years.
- Prefab fireplace sections that no longer seat flush. Many 1950s – 1980s Running Springs cabins have factory-built fireplace chimneys that have shifted over decades of freeze-thaw. The DuraFlex sections can separate, and that’s a hidden clearance problem you won’t know about without a Level 2 inspection.
DuraFlex Service in Running Springs: What Local Conditions Mean for Your Equipment
Running Springs sits at 6,000 feet, and that altitude changes how DuraFlex systems actually behave. From November through March, sub-freezing nights and heavy snow push homeowners to run wood stoves and fireplaces constantly, often with pine and cedar that hasn’t been seasoned long enough. The result is creosote that glazes to a hard, glassy stage – something sweeps rarely see in lower mountain towns like DuraFlex repair in Crestline or Arrowbear Lake. We scope Level 2 inspections and rotary creosote removal around the altitude heating cycle here because a spring cleaning often reveals a liner interior that looks more like black enamel than stainless. In one cabin off a steep second-home lot near Running Springs, we pulled a DuraFlex flex-liner termination and found the top-mount cap crushed and its screen torn from the prior winter’s snow load, with glazed pine creosote baked hard down the liner. We rotary-cleaned the flue to bare metal, replaced the crushed cap with a DuraFlex-compatible multi-flue unit, and reset the top plate so the collar seated clean against the crown. The homeowner was back to burning safely before the next cold snap.
That’s the normal pattern up here, and it’s why a generic chimney sweep from down the hill misses things. If your Running Springs home has a DuraFlex liner that’s never been scoped after a heavy snow year, the time to have it looked at is before the first fall fire.
DuraFlex Models & Products We Service in Running Springs
We service the full DuraFlex component stack across Running Springs. That includes DuraFlex SS Flex relining pipe, 316L and 304 alloy flex liner kits, factory-built fireplace chimney sections, and multi-flue and top-mount cap systems. Our crew knows exactly which coupling fits which liner generation, and we carry genuine DuraFlex cap sections, top plates, and couplings on the truck.
When a factory part is genuinely unavailable, we’ll use a quality aftermarket component that matches the existing alloy and spec. What we won’t do is mix alloys on a liner repair, because dissimilar metals in a high-temperature flue create galvanic corrosion. That’s the kind of decision you shouldn’t have to explain to a homeowner. We just do it right the first time.

AfterDuraFlex Service Pricing in Running Springs
A standard DuraFlex chimney cleaning in Running Springs typically runs $200 – $400, depending on liner length and how badly the creosote has glazed. Level 2 inspections run $250 – $450, and we recommend them for any DuraFlex system that sat through a heavy snow year or hasn’t been scoped in the last few seasons. Cap replacement with a DuraFlex-compatible unit is generally $150 – $350 installed.
What actually drives the price up here is glazing. A liner that’s coated in hard, tar-stage creosote takes longer to clean to bare metal than a lightly sooted one. We’ll give you a flat price before we start, based on what we find during the initial look. Call (833) 467-6493 for a free estimate, and we’ll tell you what your system needs and what it doesn’t.

FAQs – DuraFlex Chimney Cleaning in Running Springs
At 6,000 feet, fires don’t draft as strongly as they do at sea level. Pine and cedar produce heavy creosote vapor that condenses and hardens on the cooler upper sections of the liner. Long, slow overnight burns make it worse. The fix is more frequent cleaning during the burning season, not a different liner. Call (833) 467-6493 to schedule a mid-season sweep if your glass is staying clean but your draft is dropping.
Generally no. A snow-crushed cap has deformed metal and compromised screen welds, and straightening it leaves micro-fractures that rust through fast. We replace the cap with a DuraFlex-compatible unit matched to your chase or liner top. It’s a quick, affordable fix that restores proper draft and keeps water out. Call (833) 467-6493 for a cap inspection and price.
If your system is used regularly through the mountain burning season, start with a Level 2. This includes scoping the liner interior with a camera, checking joints and top plates, and looking for hidden damage from snow load or freeze-thaw. A Level 1 visual is fine for mid-season spot checks, but after a heavy winter, only a camera view of the liner will show glazing and pitting. Our Level 2 inspection runs $250 – $450 in Running Springs. Call (833) 467-6493 to book one.
Yes, when the liner and remaining joints are sound. We stock DuraFlex couplings and top plates specifically so we can do targeted repairs instead of quoting a full reline. If the liner itself is glazed to the point of failure or corroded through, we’ll show you the camera footage and recommend replacement honestly. No upsell, just what the pipe tells us. Call (833) 467-6493 for a repair assessment.
Most Running Springs homes with a wood-burning DuraFlex system should be swept at least once per burning season, and twice if you burn daily from November through March. The pine and cedar canopy plus 6,000-foot draft conditions produce glazing faster than any lowland or even lower-mountain town. If you’re unsure, call (833) 467-6493 and we’ll check your burn rate and liner condition.
