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 Upland, CA | Santa Ana Chimney Sweep
DuraFlex chimney cleaning in Upland is what we do every week from October through February, and we provide DuraFlex in San Antonio Heights and independent DuraFlex service across 91784, 91785, and 91786. The one thing that makes our DuraFlex work here different is what the Santa Ana winds and foothill thermal cycling do to crowns, caps, and top plates before the liner itself ever fails. We’re Santa Ana Chimney Sweep, and we work on DuraFlex flexible stainless liners in Upland’s older masonry fireplaces constantly. If your fireplace is drafting poorly or you haven’t had the liner scoped in years, call (855) 341-9658 for a free estimate.
Why Upland Residents Choose Us for DuraFlex Service
We pull, scope, and repair DuraFlex flexible stainless liners in Upland’s pre-war and mid-century homes all season long. We know how these systems were retrofitted into foothill bungalow flues and where the installs typically fall short. We’re an independent sweep, not affiliated with or authorized by DuraFlex, which means our inspection findings and repair recommendations are ours alone. Allen Becerra grew up around historic masonry fireplaces, trained in construction technology at Santiago Canyon College, and has spent the better part of two decades inspecting and cleaning chimneys across Southern California. When we scope a DuraFlex liner in Upland, we look for the same things every time: seam wear, top plate lift, crown cracking, and glazed creosote baked onto corrugations. We name the materials we use and why they matter.
We handle DuraFlex sales & service as part of our full chimney and vent safety scope. Sweep, repair, reline – handled by the same crew.

Common DuraFlex Chimney Cleaning Problems We Solve in Upland
- Top-plate and cap assemblies wind-worked loose. Santa Ana gusts off the San Gabriel base hammer chimney terminations every fall. We reseat the top plate, replace cap screws with stainless hardware, and add a screen that stays put.
- Hairline seam and corrugation wear from undersized original clay tiles. Upland’s 1920s-1950s foothill bungalows often have original clay flues too narrow for a smooth liner pull. Scoping shows wear points before they become leaks.
- Cracked masonry crowns and failed flashing above the liner termination. Sun and thermal cycling dry out and split the crown, and the DuraFlex top plate then sits in a leaking pocket. We repair the crown before the liner takes water damage.
- Hardened glazed creosote baked onto corrugations. Intermittent cold-night burning in Upland produces slick, glassy creosote that standard poly brushing skips unless the flue is scoped first. We scope first, then brush accordingly.
- Cap screens packed with leaf litter and bird nests. Foothill wind drives debris into open caps. A clogged screen restricts draft and pushes smoke back into the living room.
DuraFlex Service in Upland: What Local Conditions Mean for Your Equipment
Upland’s north-side foothill blocks along Euclid Avenue and north of Foothill Blvd were built with original brick and block chimneys whose mortar crowns are already undersized for the flue. So the crown, not the DuraFlex liner, is often the first failure we find when the Santa Ana winds rake the mountain base each fall. In flat, gas-only Inland Empire tracts to the south, a DuraFlex liner might sit untouched for a decade because nobody burns and the cap never gets stressed. In Upland’s 91784 bungalow belt, the same liner gets real winter use, and the termination above it gets wind-load year round. That’s why our DuraFlex cleaning here almost always includes a Level 2 inspection of the crown and top plate, not just a sweep of the flue walls. A clean flue isn’t a luxury – it’s what separates a working fireplace from a fire hazard.
A homeowner on a 1940s bungalow block off Euclid Avenue called us after smoke drifted back into her living room on the first cold-night fire of the season. Our tech ran a Level 2 camera down the DuraFlex liner, found the top plate lifted and the original crown split from the last Santa Ana wind event, and pulled a wad of leaf litter and a bird nest out of the cap screen before brushing the glazed creosote off the corrugations. We rebuilt the crown, reseated the top plate with a new stainless cap and screen, and the fireplace drafted clean the next evening.
DuraFlex Models & Products We Service in Upland
We service the full DuraFlex flexible liner range in Upland: the SW smooth-wall liner, the Pro flexible stainless relining kit, the Insulated wrap-insulated liner for exterior chases, and the top-plate and cap termination assemblies used on retrofits. Our parts approach is straightforward. We use genuine DuraFlex termination hardware where it’s still available for the installed generation, and quality aftermarket stainless caps and top plates from reputable venting suppliers where OEM parts are discontinued or back-ordered. If the liner itself is sound and only the cap, top plate, or crown above it has failed, we repair rather than replace. A full reline is only our recommendation when the camera shows seam separation, crushing, or heat damage along the run.

AfterDuraFlex Service Pricing in Upland
For a standard DuraFlex chimney cleaning in Upland, most jobs fall between $180 and $340 depending on flue condition and how much glazed creosote has built up. A Level 2 camera inspection adds about $150 to $250. Crown repair with proper resurfacing typically runs $400 to $800, and cap plus top plate replacement lands around $250 to $500 parts and labor. The big variable in Upland is wind damage: if the crown split and the top plate lifted, you’re looking at repair work before the sweep matters. We give flat-price quotes before any work starts, and the camera footage is yours to see. Call (855) 341-9658 for an exact quote – estimates are free.

FAQs – DuraFlex Chimney Cleaning in Upland
Santa Ana winds funnel down the San Gabriel foothills every fall and spring, and they hit chimney terminations with sustained gusting that loosens cap screws over a single season. The fix is stainless hardware with proper washers plus a reseated top plate. If the crown below is cracked, the cap will keep loosening until that’s repaired. Call (855) 341-9658 and we’ll scope the whole termination.
You need both. Upland’s 1930s bungalows were built with original clay flues that are often undersized for the liner pull, and that means seam wear where the liner corrugations rubbed during installation. A sweep cleans what’s visible. A Level 2 camera shows what’s happening along the entire run and at the top plate. In Upland, skipping the scope is how crown cracks and top plate lift go unnoticed until smoke backs up into the house.
No, it’s a masonry problem, and in Upland it’s usually the original crown from a 1920s-1950s build, not the liner. But a cracked crown lets water run down the outside of the liner and into the brick, which eventually damages both. We repair the crown and reseat the DuraFlex top plate in one visit. Waiting on this is how a $600 crown job becomes a $3,000 reline.
Yes, and cold-night burning makes it worse. Short, occasional fires in a cold flue produce condensation that bakes creosote onto the liner corrugations as a hard, glassy glaze. That’s the hardest type to remove, and it won’t come off with a basic poly brush. We scope every Upland DuraFlex system before brushing so we know what’s actually on the walls. Call (855) 341-9658 to book a sweep before the next cold snap.
Yes. We’re an independent chimney and vent safety company, not affiliated with or authorized by DuraFlex, and we service systems installed by other contractors all across Upland. We don’t need the original install records to inspect, clean, or repair the liner and termination. Our camera findings stand on their own.
