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 Claremont, CA
We provide independent DuraFlex chimney cleaning, inspection, and repair across Claremont, CA (91711 and 91767). What sets our DuraFlex work here apart is simple: Claremont has an unusually high density of true masonry chimneys with clay tile flues, and we see how DuraFlex stainless liners behave inside those older flues when deodar needles clog the caps and Santa Ana winds cycle the top plates. Call (866) 285-4905 for a free estimate.
Why Claremont Residents Choose Us for DuraFlex Service
Gil Trevino, our owner, grew up off Mission Boulevard near the old Jurupa Hills area and has spent the better part of two decades working on chimneys across the Inland Empire. He picked up building systems and ventilation fundamentals through coursework at Riverside City College before narrowing his focus entirely to fireplace and chimney work. These days he is the guy neighbors call when a damper plate is corroded through or a clay flue tile has cracked after one of those rare hard-freeze nights the valley still gets in January.
We are strictly an independent DuraFlex sales & service provider, not manufacturer-affiliated or authorized. That independence means we give you straight answers about what your liner actually needs. We use DuraFlex OEM components because aftermarket stainless parts often mismatch the liner’s alloy and wall thickness, and that mismatch is exactly where rust and gasket failures start. Most Claremont sweeps will brush your flue and leave. We name the materials we use, and we fix what the inspection turns up.

Common DuraFlex Chimney Cleaning Problems We Solve in Claremont
- Glaze-stage creosote on smooth-wall liner seams. DuraFlex SW smooth-wall liners collect creosote differently than the rough clay tile they sit inside. Homeowners in Claremont’s 91711 core who burn wood heavily in original Craftsman fireplaces get hard, shiny deposits on the liner wall, especially at the seam overlaps. That constricts draft and causes smoke-back on cold San Gabriel evenings. Standard brushing will not remove glaze-stage creosote; it takes mechanical removal and the right training.
- Cracked top-plate and cap gaskets from Santa Ana wind cycling. Claremont sits at the foot of the San Gabriels, where periodic Santa Ana events push dry, abrasive wind through the city. DuraFlex SW top-plate gaskets dry out and crack under that wind cycling and the dry-season UV. When the gasket fails, rain works down the annulus between liner and clay tile, rusting the plate and staining the damper area.
- Liner flex and rubbing against original clay tile. Improper liner support or missing insulation wrap at the damper area causes the liner to flex and rub against the original clay tile in 1900s-1950s flues. We see this constantly in the Village and tree-street homes. The stainless surface wears thin at the rub points, and a pitted liner section is a reline, not a patch job.
- Deodar needle and oak leaf packing in multi-flue caps. Village streets and college campuses are lined with mature deodar cedars and oaks. Needles drop straight onto chimney caps, and Claremont screens and caps clog far faster than in the open tract grids east toward Pomona. The result is downdraft that pushes smoke past the DuraFlex top plate and into the living room.
- Surface rust versus pitted-through liner sections. We inspect every DuraFlex liner for the difference. Surface rust on a smooth-wall section with a failed gasket usually means replacing the fitting and keeping the liner. Pitting that goes through the stainless wall means that section cannot be saved, and we will tell you plainly rather than chase a repair that will not hold.
DuraFlex Service in Claremont: What Local Conditions Mean for Your Equipment
Claremont is a small college town at the base of the San Gabriel Mountains, and unlike the prefab-heavy stock in neighboring Pomona or Rancho Cucamonga, many homes here were built as permanent residences by East Coast transplants who insisted on real masonry fireplaces. That gives Claremont an unusually high density of true brick-and-mortar chimneys in a small city, dominated by older masonry flues with clay tile liners. The 91711 core, the Village and tree streets, is mostly 1900s-1950s Craftsman, Spanish Colonial Revival, and ranch homes with original brick fireplaces and clay-tile flues. The 91767 edge includes mid-century tract housing with more prefab or insert conversions. For DuraFlex owners, this means your liner lives inside a clay tile flue that may have been swept and maintained for decades, and the way the liner interacts with that old flue is the whole story. Clay tile expands and contracts at a different rate than the stainless liner inside it. Add Claremont’s cool winter evenings and Santa Ana wind events, and the liner moves. That movement is what wears gaskets, loosens top plates, and eventually rubs through liner walls against the original tile. A generic DuraFlex page will never tell you that.
On a 1920s Spanish Colonial Revival off Harvard Avenue near the Village, our tech found a DuraFlex SW liner under a clogged multi-flue cap packed with deodar needles and a cracked top-plate gasket. We cleared the cap and flue, replaced the gasket and cap screen, removed glaze-stage creosote from the smooth-wall liner, and the fireplace drafted cleanly again on a cold evening test burn with no smoke-back. That is what DuraFlex repair in Upland and Claremont actually looks like.
DuraFlex Models & Products We Service in Claremont
We clean, inspect, and repair the full DuraFlex stainless liner line: DuraFlex SW smooth-wall stainless flexible liner, DuraFlex Pro stainless flexible liner, DuraFlex Duraliner pre-insulated liner kit, and DuraFlex direct-vent and insert connection kits. When a fitting fails, we source OEM DuraFlex top plates, caps, support brackets, and connector kits, not hardware-store substitutes. For Claremont turnaround, we keep common top-plate gaskets, cap screens, and connector components stocked so a typical fitting replacement does not wait on a parts order. If the inspection shows a liner section pitted through or glaze-damaged past saving, we recommend relining and we will show you the camera footage that backs up the recommendation.

AfterDuraFlex Service Pricing in Claremont
DuraFlex chimney cleaning and inspection in Claremont typically runs between $180 and $340 depending on flue height, liner condition, and whether we are clearing a clogged multi-flue cap at the same time. A cracked top-plate gasket replacement usually adds $60 to $140, again depending on the cap size and access. Full relining jobs are quoted per job after a camera inspection, because liner length, insulation wrap, and connector kit needs vary from chimney to chimney. Our free estimate includes a visual inspection of the liner from the firebox and a written scope of what we found. Call (866) 285-4905 for an exact quote. Cleaning is step one; when we find something, we will show you the photo of it before we ever hand you a repair number.

FAQs – DuraFlex Chimney Cleaning in Claremont
Not necessarily, and in Claremont the first thing we check is the cap. Deodar needles and oak leaves from Village street trees pack the multi-flue caps common on these original brick chimneys, and a clogged cap creates downdraft that pushes smoke past the top plate regardless of liner condition. If the cap is clear, we look next at glaze-stage creosote on the smooth-wall seams and a cracked top-plate gasket. We diagnose in that order because in Claremont it is almost always the cap or the gasket before it is the liner itself. Call us and we will do the same inspection on yours.
Smooth-wall stainless collects creosote differently than rough clay tile because the surface does not give deposits the same grip. Instead of building up evenly like it does on tile, creosote on a DuraFlex SW liner concentrates at the seam overlaps and any place the liner changes direction. In 91711 homes with original Craftsman fireplaces that burn wood heavily, those seam deposits can reach glaze stage faster than the old tile ever did. That is why we check the seams specifically during every DuraFlex cleaning in Claremont.
Yes, and that is exactly what we do whenever the liner wall itself is still sound. A cracked top-plate gasket or a corroded cap screen is a fitting failure, not a liner failure. We use DuraFlex OEM top plates, caps, and support brackets so the replacement matches the liner’s alloy and wall thickness. We only recommend relining when the smooth-wall section is pitted through or has glaze-stage creosote damage that mechanical removal cannot safely clear. If your liner is still good, we keep it and replace the fitting. Call (866) 285-4905 and we will tell you which situation you have.
They do, and mostly through the top plate gasket. Santa Ana events bring dry, gusting wind down from the San Gabriels, and that wind cycling flexes the stainless top plate against the gasket. Over several seasons the gasket dries out, cracks, and lets rain down the annulus between the liner and the original clay tile. That water is what rusts the plate and stains the damper area. Claremont’s dry-season UV does the same thing to exposed rubber. We check the top-plate gasket on every DuraFlex inspection here.
A Level 2 inspection on a DuraFlex-lined chimney means we run a camera from the firebox to the cap and document the liner wall, the seam condition, the top plate, the gasket, and the cap screen. In Claremont’s older 1900s-1950s homes we are specifically looking for liner rub against the original clay tile, glaze-stage seam deposits, and any debris that has worked past the cap. You get the camera footage, not a verbal summary. If we find something, we show you the image and explain what it means before we quote any repair.
