Why Westmont Residents Choose Us for DuraFlex Service
Most of the DuraFlex work we do in Westmont starts with a simple fact: these chimneys are old, and they were built for wood fires that stopped being a daily habit decades ago. We also provide DuraFlex service in View Park-Windsor Hills. Our owner, Norm Castillo, has been working South LA County chimneys for close to two decades, and he’ll tell you the same thing he tells every Westmont homeowner. The liner might be fine. The cap is probably not. We see it on block after block of 90047 bungalows.
Ashwood Chimney Sweep works with DuraFlex sales & service because these are professional-trade liner, cap, and damper systems, not big-box substitutes. We keep genuine DuraFlex OEM parts on hand for caps, liner connectors, and damper gaskets, which means a Westmont repair doesn’t stall while we wait on a shipment. When a part is discontinued or backordered, we tell you before installing an aftermarket equivalent. That’s the difference between a contractor who stocks the brand and one who just names it.
We’re also the same crew that handles the rest of the chimney. Clean, inspect, repair in one call. If your uncapped flue needs a DuraFlex cap before we can sweep it, we install the cap that day. If the mortar crown is spalled, we repoint it. You don’t get handed off to a masonry crew you’ve never met.

Common DuraFlex Chimney Cleaning Problems We Solve in Westmont
- Pigeon and starling nests blocking uncapped flues. Westmont’s dense bungalow blocks are full of uncapped masonry chimneys, and birds find them faster than homeowners do. We routinely pull nests, twigs, and years of dry leaf litter before a DuraFlex liner can even be inspected. This isn’t a once-in-a-while thing here. It’s most jobs.
- Corroded liner connectors where dampness meets old masonry. When a Westmont chimney goes uncapped through a rain season, water gets into the clay tile and sits against the DuraFlex stainless connector at the appliance. We see corrosion at those joints on converted fireplace inserts and legacy wall heaters, and it’s usually caught during a cleaning or Level 2 inspection.
- Dry-rotted damper gaskets and top-sealing assemblies. Westmont’s low-humidity, dusty air does a number on rubber and fiber gaskets in DuraFlex top-sealing dampers. They stick, crack, and let debris fall into the firebox. We replace gaskets with OEM parts when available and adjust the assembly so it seals tight.
- Loose or rusted cap screens and mounting hardware. Years of bird activity and dry-season dust put real stress on DuraFlex cap screens on Westmont rooftops. We tighten, reseat, or replace mounting brackets and screens before they fail and drop into the flue.
- Spalled mortar crowns and cracked flue tiles found during cleaning. The bigger local issue in Westmont isn’t creosote. It’s deteriorated masonry. We inspect the crown and upper flue tile during every DuraFlex cleaning, because if the crown is gone, a new cap won’t save the chimney by itself.
DuraFlex Service in Westmont: What Local Conditions Mean for Your Equipment
In the older bungalow blocks of 90047, uncapped masonry chimneys are a magnet for pigeons and starlings. That’s not a line we use on every city page. It’s the Westmont reality. On a block of small Spanish-style stucco bungalows, our tech recently pulled a dense pigeon nest and years of dry leaf litter from an uncapped clay flue before the DuraFlex liner could even be inspected. We offer similar DuraFlex service in Inglewood. The original cap was gone, the crown had spalled, and the liner connector at the insert showed early corrosion. We installed a DuraFlex multi-flue cap, repointed the crown, swept the flue, and checked the liner. No authorization by DuraFlex is claimed, simply our own independent work.
That sequence, cap first, then masonry, then liner, is the standard order of operations in Westmont. The mild, dry climate means creosote buildup stays moderate. The damage comes from open flues, nesting birds, and decades of deferred maintenance on original clay tile. A generic DuraFlex service page won’t tell you that. It matters here.
DuraFlex Models & Products We Service in Westmont
We service the full range of DuraFlex product lines installed in Westmont homes, including DuraFlex stainless-steel flexible chimney liner kits, multi-flue and single-flue caps, top-sealing damper assemblies, and fireplace insert liner components. We work on liners that vent wood-burning fireplaces, gas inserts, and converted wall heaters, all common in this housing stock.
When a DuraFlex part fails, we always tell you whether we’re installing genuine OEM or a quality aftermarket equivalent, and why. Repair comes before replacement when the liner or cap is structurally sound. If corrosion, joint separation, or cracked components make repair unsafe, we recommend full replacement and show you the evidence before any work is done.
Ashwood handles the whole flue, not just the easy parts, including DuraFlex in West Athens. We stock common DuraFlex cap hardware, damper gaskets, and liner connectors locally for fast turnaround in Westmont. Less common parts we source through professional-trade supply houses, the same channels that feed certified chimney contractors nationwide.

AfterDuraFlex Service Pricing in Westmont
Chimney cleaning and inspection on a DuraFlex-equipped fireplace in Westmont typically runs $180 to $340, depending on flue condition, cap type, and access. Adding a DuraFlex cap installation or top-sealing damper replacement pushes the job higher, usually $250 to $600 for the part and labor combined. Full liner replacement with DuraFlex stainless runs $1,800 to $3,500 depending on length, diameter, and whether we’re relining a single flue or a multi-flue masonry chimney.
What drives cost here is masonry condition, not creosote. If your crown needs repointing or the clay tile is cracked, that work gets priced before any DuraFlex component goes in. Our free estimate includes a camera inspection report with photos, so you see exactly what we see. Call (833) 805-3229 for an exact quote on DuraFlex service in Westmont.

FAQs – DuraFlex Chimney Cleaning in Westmont
Because the original caps on 1920s through 1950s masonry chimneys are often missing entirely, and without a cap the flue fills with pigeon nests, starling debris, and dry leaf litter. We cannot properly clean or inspect a chimney in that condition until the flue is capped. The cap installation and the cleaning happen on the same visit.
Yes, in most cases. The original clay tile liners in Westmont’s older bungalows are often cracked, spalled, or offset, and a DuraFlex stainless liner is a proven solution for relining without full demolition. We also handle DuraFlex repair in Lennox. The liner runs through the existing flue, and we inspect the surrounding masonry and crown before installation to ensure the structure is sound enough to support it.
The low humidity and constant dust dry out rubber and fiber gaskets faster than you’d see in a coastal city with more moisture. Gaskets crack, dampers stick, and debris falls through. We inspect damper gaskets on every DuraFlex-equipped chimney we clean in Westmont, and we replace them with OEM components when they’ve failed. Call (833) 805-3229 for a free estimate.
A Level 2 inspection is a video scan of the entire flue interior plus a visual check of the appliance connection, cap, crown, and exposed masonry. On a DuraFlex system, we’re looking for joint separation, corrosion at the liner connectors, gasket failures, and any debris blockages. It’s the inspection we recommend whenever a Westmont home has changed appliances, had a chimney fire, or gone years without service.
Yes. Installing a DuraFlex cap or liner on a chimney with a spalled crown or crumbling brick is a waste of your money, and we won’t do it. We repoint mortar joints and repair crowns first, then install the cap or liner. The masonry work and the DuraFlex installation are handled by the same crew, so the job doesn’t stall between contractors.
