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 | Corona Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Claremont, and the short version is this: a DuraFlex system here usually fails at the top plate or the insulation wrap long before the stainless liner itself gives out. That’s why our DuraFlex work in Claremont starts with a Level 2 inspection of the crown, cap, and what the liner is actually enclosed by, not just a brush-and-go sweep. Call (855) 382-6159 and we’ll tell you what you’re actually dealing with.
We’re not the manufacturer. We’re not an authorized dealer. We’re technicians who have pulled apart enough DuraFlex installations in Claremont homes to know exactly how this brand ages in inland heat and Santa Ana cycles. DuraFlex sales & service is what we do because the brand shows up constantly in the older chimneys around here. When you need a sweep, a cap replacement, or an honest assessment of whether your liner still has years left in it, we’re the crew that fixes what we find.
Why Claremont Residents Choose Us for DuraFlex Service
While we also handle DuraFlex service in La Verne, most chimney companies in Claremont can run a brush through a flue. Far fewer can tell you whether the DuraFlex joints at your adapter plate are loosening, whether the insulation wrap has degraded to the point of heat transfer, or whether the crown failure above your liner means the whole system needs attention now or can wait a season. We can, because we’ve done it across Claremont’s Village, the College area, and the 1960s-80s tracts on the north and east edges.
Nolan Ferris, our owner, grew up in South Corona and spent over a decade inspecting and cleaning flues across the Inland Empire before narrowing his focus entirely to chimneys. He learned HVAC fundamentals and combustion systems through Norco College’s vocational program, and that mechanical background is why our DuraFlex inspections here—and our DuraFlex repair in Upland—read more like a diagnostic than a checklist. We document what we find, show you the photos, and give you a straight answer on repair versus replace. As an independent provider, we buy genuine DuraFlex components when a liner, top plate, or cap needs replacement, and we keep the common wear items stocked so Claremont jobs don’t stall waiting on parts.

Common DuraFlex Chimney Cleaning Problems We Solve in Claremont
- Loosened joints and adapter plates. DuraFlex stainless flexible liners hold up well, but the connector joints and adapter plates take the thermal expansion. After enough hard-wood fires during Claremont’s November-February burning season followed by long hot idle months, those connections loosen. We catch this during sweeping and re-secure before it becomes a leak path or draft killer.
- Degraded insulation wrap. On College-adjacent Craftsman homes with unlined brick flues, we regularly find the insulation around a DuraFlex liner crumbling or missing entirely. That matters because without the wrap, heat transfers into brick that was never meant to handle it alone. Creosote accumulation climbs faster, and your draft gets inconsistent.
- Rusted top plates and caps. Claremont’s long rainless stretch through summer and fall bakes every cap and plate. Then winter storms hit. We replace rusted DuraFlex top plates and caps regularly, and we almost always catch it before water has damaged the firebox below.
- Sound liner, failing masonry surround. A 1920s single-wythe chimney in Claremont may have a solid DuraFlex liner, but the original brick around it is spalling or the mortar crown is shot. We’ll tell you the liner is fine and fix the masonry instead of selling you a reline nobody needs.
- Creosote from hardwood fires. Claremont’s dry air means firewood seasons fast, and many residents here burn oak and eucalyptus. That combination produces creosote quickly, especially when a liner is undersized or the draft is marginal. Our creosote removal service treats the stage of buildup seriously, and we classify what we find so you know what it means for fire risk.
DuraFlex Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s the thing about Claremont that changes how we approach every DuraFlex job: in the College-adjacent Craftsman homes built between 1910 and 1930, many chimneys are single-wythe brick with no clay tile liner at all. No flue tile. Just brick. A DuraFlex flexible liner may be installed, but what surrounds it is original masonry that was never designed for modern open-door fireplaces or inserts. So before any sweep, we confirm what the liner is actually enclosed by. We pull the boot, inspect the wrap, check the top plate seating, and document what’s above and below the stainless section. If you own one of these homes and the company that installed the liner twenty years ago never mentioned the missing clay tile, that’s the conversation you should have had. We’ll give it to you now. Between the dry rot in mortar crowns from Claremont’s rainless season and the fast creosote accumulation from Santa Ana-dried wood, these old chimneys demand methodical inspection, not a quick brush. That’s the work we do.
DuraFlex Models & Products We Service in Claremont
We service the full DuraFlex lineup as it appears in Claremont homes: the Stainless Steel Flexible Chimney Liner in round and oval, the Insulated Flexible Liner Kit, the Pro Flexible Relining System, and the Top Plate and Multi-Flue Cap assemblies. Where the existing system is DuraFlex, we use genuine DuraFlex components for replacement liners, top plates, and caps. For wear items like clamps and minor hardware, we use quality aftermarket where safety is unaffected. Our trucks carry the common DuraFlex replacement parts so Claremont jobs move fast once we confirm what needs doing. You won’t wait a week for a cap or a joint kit to ship.

FAQs – DuraFlex Chimney Cleaning in Claremont
Yes, with a proper inspection first. The DuraFlex liner itself is not the problem; the missing clay tile means the brick surround is absorbing heat it wasn’t built to handle. We sweep it carefully, inspect the insulation wrap and top plate, and document what the liner is enclosed by. If the brick surround is spalling or the crown is deteriorating, we flag it and fix what’s needed. Call (855) 382-6159 and we’ll schedule the Level 2 so you know exactly what you have.
Every year if you burn regularly. Claremont’s dry climate and hardwood usage build creosote faster than coastal areas, and a DuraFlex liner doesn’t change that. Burn a cord or more a season and annual sweeping is the minimum. If your fires are occasional, every two years may work, but we’ll tell you after inspecting whether your burn pattern shortens that interval. Call (855) 382-6159 for a free estimate and we’ll assess your schedule.
Usually no. A crumbling mortar crown is a masonry problem, not a liner failure. The DuraFlex liner can be perfectly sound while the crown above it lets water and debris into the flue. We repair crowns and keep the liner you already have, because the liner isn’t the failure point. We’ll inspect both and tell you exactly which one needs work. Call (855) 382-6159 and we’ll give you an honest read without pushing a reline.
Yes. We keep genuine DuraFlex replacement caps and top plates in stock, including multi-flue assemblies. Rusted caps are one of the most common failures we see in Claremont, and the fix is straightforward when caught early. If water has already gotten past the cap, we’ll inspect the firebox and crown for damage and quote that repair separately. Call (855) 382-6159 for a free estimate and we’ll check your cap before the next burn season.
It depends on the condition of the brick. If the single-wythe brick is structurally sound, a DuraFlex flexible liner with proper insulation is often the right fix and avoids a tear-out. If the masonry is spalling or the surround is failing, a rebuild may be the honest answer. We’ll show you the photos and the measurements so you make that call with eyes open. We’re not preservation-minded by accident; we know Claremont owners want to keep original chimneys. Call (855) 382-6159 and we’ll assess what your chimney actually needs.
