Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Lake Arrowhead Residents Choose Us for DuraFlex Service
Allen Prescott built San Bernardino Chimney Sweep around one idea: a chimney company should find problems and fix them, not just sweep and run. He grew up near the Kendall Drive corridor in San Bernardino and has spent the better part of three decades on Inland Empire chimneys, so when we look at a DuraFlex liner in a Lake Arrowhead A-frame, we know what mountain weather does to factory-built systems. Our crew works on DuraFlex Builder Series, Pro Series, stainless liners, and insulated flex kits regularly. We stock OEM DuraFlex components for critical connections and quality aftermarket caps where the spec matches. When we inspect a flue, we document what we find with a camera, and we hand you the report. That’s the whole job. Learn more about our DuraFlex sales & service work across the region.

Common DuraFlex Chimney Cleaning Problems We Solve in Lake Arrowhead
Here’s what we actually run into when we pull up to a Lake Arrowhead cabin with a DuraFlex system.
- Creosote glaze on stainless liners. Pine burns hot and fast, but in a tight A-frame firebox with limited draft, it produces dense, tarry creosote that hardens into a shiny glaze on stainless steel. This is the single most common spring find in Lake Arrowhead DuraFlex systems.
- Cracked or spalled exterior crowns and caps. Snow sits on chimney crowns up here. It melts, refreezes, and pries apart concrete and mortar. DuraFlex caps that looked fine in October can be split by March.
- Rusted dampers and firebox components. Cabins that sit empty midweek stay damp inside. With no fire to dry things out, factory dampers and metal firebox parts rust faster than most owners expect.
- Liner joint separation in older DuraFlex installs. Snow load on exterior chimney stacks puts real weight on roof-line penetrations. We see joints that start to separate in installs that haven’t been inspected in years.
- Insurance documentation gaps. Rental owners often discover their insurer wants a recent Level 2 inspection on file. We provide that documentation after every cleaning.
DuraFlex Service in Lake Arrowhead: What Local Conditions Mean for Your Equipment
Lake Arrowhead sits at roughly 5,000-plus feet in the San Bernardino Mountains, and most of the housing stock is 1950s-1990s cabins, A-frames, and second-home chalets built into sloping lots. Many of these have exterior chimney stacks that take direct snow and ice on the roof line. Here’s what that means for DuraFlex owners specifically: because most cabins are second homes, the typical flue sits cold and damp for months between winter burns. Then an owner arrives for a long weekend, burns a winter’s worth of pine in three days, and drives back down the hill. That pattern produces hard creosote glaze that a flatland sweep never sees. Add freeze-thaw to the exterior stack, and a spring cleaning in Lake Arrowhead often turns up cracked crowns and spalled masonry alongside the creosote. A crew that only works flatland chimneys doesn’t know to look for the combination of both problems at once. We do. It’s the same reason we watch the roof line closely on every DuraFlex install we inspect up here. If you live anywhere in the 92352 zip code, your chimney ages differently than one in the valley, and the service should reflect that.
DuraFlex Models & Products We Service in Lake Arrowhead
We service the DuraFlex Builder Series, Pro Series, Stainless Steel Liner, and Insulated Flex Kit product lines. For critical connections like liner joints and stainless sections, we use genuine OEM DuraFlex components. For caps, dampers, and other non-critical parts, we use quality aftermarket replacements that meet the same spec. We repair when the liner integrity and firebox are sound. We recommend replacement when corrosion, joint failure, or spalling compromises the system. That’s the honest way to do it, and it’s the only way we work.

AfterDuraFlex Service Pricing in Lake Arrowhead
What you pay depends on what we find. A standard DuraFlex chimney cleaning and Level 1 inspection typically falls in the $180-$340 range for Lake Arrowhead homes. If we uncover creosote glaze that requires more aggressive removal, or if a cap replacement or crown repair is needed, we give you a flat price before any additional work begins. A Level 2 camera inspection, which many insurers and rental platforms want before the season, adds documented evidence of liner condition. Our estimates are free, and nothing gets recommended without camera footage you can see for yourself. Call (877) 516-7159 for an exact quote on your DuraFlex system.

FAQs – DuraFlex Chimney Cleaning in Lake Arrowhead
Weekend-only burning is exactly why. Pine produces tarry creosote, and when your flue cools completely between visits, that creosote hardens instead of burning off. A lake cabin that goes from cold to hot in the span of a few hours creates the perfect conditions for glaze. Call (877) 516-7159 to schedule a cleaning if you can’t recall the last one.
Get it replaced before the next rain or snow. A cracked cap lets water into the flue, and water plus creosote makes an acidic paste that eats at stainless liners. We stock DuraFlex-compatible caps and can replace yours during a routine service visit. Call (877) 516-7159 and we’ll take a look.
In most cases, yes. A Level 2 inspection includes camera documentation of the flue interior, which is what insurers and rental platforms typically request after a change in ownership, a chimney fire, or before renting a property. We provide a documented report you can forward. Call (877) 516-7159 to confirm what your insurer specifically requires.
It depends on what the camera shows. If the liner has minor corrosion or a single compromised joint, we can often repair it with OEM DuraFlex components. If the liner is spalled through in multiple places or separated at the joints, replacement is the safe call. You’ll see the footage and make the call with the facts in front of you.
Water gets into tiny cracks in the crown, cap, and masonry, then freezes and expands. Repeat that dozens of times over a winter and you get spalling. In Lake Arrowhead, we see cracked crowns on exterior stacks every spring. The fix is straightforward if caught early. Call (877) 516-7159 for a spring inspection before the rental season starts.
