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 Lennox, CA | San Bernardino Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and repair across Lennox, ZIP 90304. The thing that makes our DuraFlex work here different is simple: most “creosote” calls in this unincorporated pocket turn out to be LAX and 405 particulate caked on the cap and arrestor mesh, not a chimney fire risk. We clean the top termination first, scope the liner after, and tell you plainly what needs work and what can wait. Call (877) 516-7159 for a free estimate.
Why Lennox Residents Choose Us for DuraFlex Service
DuraFlex liners, top plates, and terminations are in hundreds of homes across Lennox, and we work on them weekly. Allen Prescott, our owner, has spent the better part of three decades on Inland Empire chimneys, and he’ll tell you the same thing he tells every homeowner: a clean flue isn’t a luxury – it’s just how you keep the fire where it belongs. We know how DuraFlex SW smooth-wall liners behave after years of low-burn use, how Pro double-wall sections hold up in a 1950s chase, and what happens when a cap screen sits under a flight path for three winters. That hands-on familiarity matters more than any brochure claim.
We’re also local to the LA Basin’s grit belt, not some dispatch service sending whoever’s available. When we arrive at a Lennox house, we already know what the 405 does to a chimney cap and what settling has done to the original clay flue tiles under your liner. For more on our full DuraFlex lineup, see our DuraFlex sales & service page.

Common DuraFlex Chimney Cleaning Problems We Solve in Lennox
- Cap and spark-arrestor mesh fouling with LAX and 405 grit. The fine black diesel and jet particulate that drifts over Lennox darkens and cakes on DuraFlex caps exactly like creosote. Homeowners call us in a panic, sure their chimney’s about to ignite. We clear the mesh, show them the difference on camera, and usually find light soot underneath.
- Cracked original clay flue tiles under the liner. Lennox’s post-WWII stucco homes have settled and shifted through decades of earthquake movement, and the original clay tiles inside the chase crack and break. That lets a DuraFlex liner run unseated or rub against broken tile edges instead of a smooth round path. We catch this with a scope, not a guess.
- Hardened soot and creosote in liner seams. Lennox chimneys get lit a handful of times a year, so soot sits for months and bakes into the seams of flexible stainless liners. It doesn’t burn off the way it does in a daily-use fireplace. It hardens into a scale that reduces draft and needs mechanical brushing, not just a chemical treatment.
- Missing or torn cap screens on rental stock. A large share of Lennox homes are rentals, and cap screens go missing for years. Birds and rodents nest in the annular space around the liner top. We’ve pulled nests, carcasses, and enough nesting debris to completely starve the draft on the first cold-evening fire.
- Marine-layer damp and Santa Ana cycling on cap seams and top plates. Lennox sits in the coastal basin where damp marine air alternates with dry Santa Ana wind. That cycle works on the cap seams and top plate fasteners, loosening them and letting water wick into the liner top. We reseat and reseal as part of a standard sweep when the camera shows it’s needed.
DuraFlex Service in Lennox: What Local Conditions Mean for Your Equipment
Lennox sits directly under LAX approach and departure paths and alongside the 405, and that shapes every DuraFlex service call we do here. The black film on most DuraFlex caps and arrestor screens in this unincorporated pocket is largely jet and diesel particulate, not creosote. Homeowners see it and assume a chimney fire is brewing. We don’t blame them. But the first move isn’t a liner scope. We inspect and clean the top termination first, because that grit layer can mask a hairline crack in the cap or top plate. Only after the top is clear do we run the camera down the liner. On a small single-story stucco rental off Lennox Boulevard in 90304, our crew pulled a DuraFlex cap whose mesh was packed solid with a greasy black film the tenant was sure was creosote from a chimney fire. A camera run after clearing it showed only light soot and one hairline crack in the original clay tile at the top of the chase. We set a new DuraFlex-compatible stainless cap with fresh arrestor mesh, documented the tile crack with photos for the landlord, and flagged the liner seating for a follow-up Level 2 inspection before the next heating season. That’s the Lennox pattern: the grit gets blamed, the clay tile underneath is the actual issue.
DuraFlex Models & Products We Service in Lennox
We service the DuraFlex product families most common in Lennox homes: SW smooth-wall flexible stainless liner kits, Pro double-wall flexible liner systems, and rigid stainless pipe sections used for exterior runs and stove tie-ins. We also handle multi-flue top plates and stainless rain caps with spark-arrestor mesh. When the existing install is a genuine DuraFlex system, we fit genuine DuraFlex liner components and top plates. Where the OEM profile has been discontinued, we use quality aftermarket caps and arrestor mesh that match the flue dimensions. But we won’t sell a liner into a chase the camera shows is cracked, misaligned, or undersized. That’s a rebuild or reline decision, not a parts swap.

AfterDuraFlex Service Pricing in Lennox
Chimney sweeping in Lennox generally runs $180 to $340 for a standard cleaning of a DuraFlex-lined flue with a single-story chase access, depending on soot volume, cap condition, and whether we’re clearing arrestor mesh as part of the sweep. A Level 2 camera inspection with a written photo report typically falls in the $250 to $450 range. Cap replacement, top plate resealing, and creosote removal are quoted separately after we see the actual condition. A free estimate gives you the exact number before any work is booked, and we do not recommend liner work without camera evidence you can see with your own eyes. Call (877) 516-7159 to get a line-item quote for your Lennox home.

FAQs – DuraFlex Chimney Cleaning in Lennox
Probably not. In Lennox, that black film is usually jet and diesel particulate from LAX flight paths and the 405, not creosote from your fires. We clear the mesh, run a camera down the flue, and tell you exactly what’s there. If the soot layer inside is thin, there’s no fire-risk story here. Call (877) 516-7159 to book a sweep and see for yourself.
Because the original clay flue tiles in Lennox homes have cracked and shifted from decades of settling and earthquake movement, and a flexible liner running against broken tile edges is a different animal than one seated in a smooth, modern chase. We inspect the top of the chase and the liner seating before we charge you for a cleaning you might not need until the tile issue is documented.
Yes, and in Lennox that sparse usage can actually make things worse. Soot and creosote sit and harden in the liner seams for months instead of baking off, and the cap screen keeps collecting grit from the 405 whether you burn or not. An annual sweep keeps the flue clear and gives us a camera look at the top plate and arrestor before a blocked mesh starves your draft on the first fire of the season.
We can. If the cap has been gone, we expect birds, rodents, or at minimum a packed nest in the annular space around the liner top, and we clear all of it before the sweep. The camera then shows whether the liner itself is still sound. Many landlords get a photo report for their records. Call (877) 516-7159 and we’ll tell you what’s in there.
For a DuraFlex liner in a Lennox home where the original clay tile may be cracked, a Level 1 visual check isn’t enough. We recommend a Level 2 camera inspection on any first-time service call where the home predates the liner or the cap has been missing or damaged. That gives us the liner seating, the tile condition, and the top plate in one run, with photos you keep.
