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 Chatsworth, CA
Chimney Sweep Valencia provides independent DuraFlex chimney cleaning and repair across Chatsworth, including hillside neighborhoods off Topanga Canyon Boulevard. We’re not authorized or endorsed by DuraFlex, and that’s the point: our recommendations come from what we see in the flue, not from a manufacturer’s playbook. If your DuraFlex-lined fireplace smokes when the Santa Anas kick up, call (866) 472-5217. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Our techs work on DuraFlex systems every week. Stainless flexible liners, rigid sections, prefab venting, caps. We know how these stacks are put together and where they fail in this climate, because that’s where the calls come from.
Why Chatsworth Residents Choose Us for DuraFlex Service
Chatsworth’s housing stock runs toward mid-century ranch houses and 1960s-70s tract homes. Many still have their original masonry fireplaces with clay tile flues; some of the newer places out west have prefab metal chimneys. When a DuraFlex liner gets installed, whether as a reline on an old masonry stack or as part of a prefab setup, it changes how the whole system needs to be maintained.
That’s where we come in. We’re a full-service chimney and venting company, not a sweep-only outfit. If we find a crack in a liner joint during a cleaning, we can address it. If the cap is crushed, we replace it. If the firebox panels are warped, we tell you plainly and quote the repair. Marcos Maddox, our owner, learned the mechanical and safety fundamentals through the HVAC and building systems programs at College of the Canyons, then spent years working chimneys across the Santa Clarita Valley before starting Chimney Sweep Valencia in 2012. He’s the guy neighbors recommend when they don’t want to be upsold on work they don’t need.
One call covers cleaning, lining, repair, and venting. That matters in Chatsworth, where a windy season can turn a small cap problem into a smoke-filled living room fast.

Common DuraFlex Chimney Cleaning Problems We Solve in Chatsworth
- Liner joint and connector failure. DuraFlex flexible liners are joined at the top plate and the appliance collar. Chatsworth’s hot summers followed by Santa Ana wind cycling work those connections loose. We find cracked joints letting smoke and creosote escape behind the flue, where you can’t see it until it’s a problem.
- Corrosion at the cap and top plate. Wind-driven grit and winter rain off the valley beat on stainless caps. Where the metal is thin or the seal at the fasteners has given out, rust perforation starts. We see it most on older installations that haven’t been re-sealed in years.
- Damper and firebox component wear. The factory damper and firebox panels in DuraFlex-equipped prefab units warp and crack from repeated hot/cold swings. That warping is a common source of smoke rollout, and a sweep alone won’t fix it.
- Blocked or misaligned termination. When wind-blown debris loads onto a DuraFlex cap, the liner’s draft collapses. The appliance soots up far faster than expected, and you smell smoke inside even when the flue is technically open.
- Creosote buildup in the corrugations. Flexible stainless liners have corrugated walls. Creosote collects in those ridges faster than on smooth clay tile, especially with the dry-season wood burning we see across Chatsworth. A Level 2 inspection tells us how much is too much.
DuraFlex Service in Chatsworth: What Local Conditions Mean for Your Equipment
Here’s the thing about Chatsworth hillside lots off Topanga Canyon Boulevard: they sit right in the Santa Ana wind path. That’s not a minor detail. When the winds come through, they snap limbs off the old oaks and eucalyptus. Those limbs land on roof caps. Homeowners call us saying the flue is blocked, and sometimes it is, but just as often the real problem is a crushed or dislodged termination on a DuraFlex cap up top.
We ran a job on a ranch house in those hills last season. Homeowner reported smoke backing into the room from a DuraFlex-lined prefab fireplace after a windy week. Our tech went up first and found a downed limb had crushed the stainless cap and bent the top plate. We pulled the cap, cleared the sooted termination, and set a new multi-flue-rated cap with a fresh gasket and sealed plate. Draft came back immediately, and a Level 2 inspection confirmed the liner itself was sound. The fix was a cap, not a full reline. That’s the difference between knowing what you’re looking at and guessing.
The dry heat does its own work too. Semi-arid summers shrink and crack mortar and flue tiles over time. Then winter rains get into those cracks and you get spalling, blockages, and draft problems. A DuraFlex liner inside a deteriorating masonry chimney still needs the surrounding structure to be sound. We inspect both.
DuraFlex Models & Products We Service in Chatsworth
We service the full range of DuraFlex chimney products common in Chatsworth homes. That includes DuraFlex SS stainless steel flexible relining kits, DuraFlex Pro flexible stainless liner systems, rigid stainless chimney liner sections, and the prefab fireplace venting and cap assemblies found on newer builds in the west end of town.
When a component needs replacement, the decision is straightforward. If the original system is still serviceable, we fit OEM DuraFlex components: caps, top plates, dampers, and liner sections matched to the existing stack. If OEM parts are discontinued or lead times stall a repair, we use quality aftermarket stainless. We don’t stock shelves of parts and we don’t pretend every component has to come from the same factory. What matters is that the part fits the system and seals correctly. If a liner is cracked through or the firebox is compromised, we say so and quote replacement rather than patch it.

FAQs – DuraFlex Chimney Cleaning in Chatsworth
Not necessarily. In Chatsworth, wind-driven smoke backup usually means the cap is compromised: crushed by a limb, clogged with debris, or the top plate seal has failed and the draft is collapsing. We check the termination first, then the liner. Call (866) 472-5217 for an inspection.
For any repair or relining work on a DuraFlex system, yes. A camera inspection shows the condition of the liner joints, the firebox, and the cap. It’s the only way to know whether you need a patch or a full reline. We include photo documentation so you see what we see.
We can. Where the original system is still serviceable, we fit OEM DuraFlex caps, top plates, dampers, and liner sections matched to the existing stack. If a part is discontinued or would take too long to arrive, we use quality aftermarket stainless and tell you why up front. Call (866) 472-5217 with your model details.
It does. Chatsworth summers are hot and semi-arid. Mortar dries out, cracks form, and winter rain gets into those openings. Over time you get spalling and blockages. A DuraFlex liner inside a deteriorating masonry chimney still depends on the structure around it. We inspect both.
At least once a year, and more often if you burn regularly through the dry season. Chatsworth’s climate creates a heavier creosote load, and the corrugated walls of a flexible liner collect it faster. If the Santa Anas have been active, get the cap checked at the same time. Call (866) 472-5217 to schedule.
