Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We clean and service DuraFlex chimney systems across Fontana, covering 92334, 92335, 92336, and 92337. The difference with our DuraFlex work here comes down to one thing we see every week: Fontana’s long dry spells and Santa Ana winds put specific stress on caps, flashing, and idle prefab fireboxes. Nelson Quijada leads our crew, and we handle everything from routine creosote removal to Level 2 inspections and liner repairs. Call (866) 520-4943 for a free estimate.
Why Fontana Residents Choose Us for DuraFlex Service
We’re an independent chimney service company, not a DuraFlex dealer or manufacturer affiliate. That matters because our recommendations come from what we actually find inside flues and fireboxes, not from moving product. Over nearly twenty years working on Southern California chimneys, our crew has pulled apart thousands of DuraFlex systems in the same kinds of homes that fill Fontana’s tracts and older blocks. We know which parts fail and why. We stock genuine DuraFlex OEM components for caps, liners, and top plates, and we use UL-listed aftermarket parts only where it genuinely makes sense, like clamps and sealants. DuraFlex sales & service is our bread and butter across the Inland Empire.
Nelson Quijada grew up off Cahuenga Boulevard and spent two decades working on hillside homes and mid-century bungalows before building Firebrick around flue systems, firebox masonry, and draft diagnostics. That same eye gets applied to every Fontana chimney we open, whether it’s a 1958 masonry stack in 92335 or a 1990s prefab in 92337, and the same care goes into our DuraFlex service in Bloomington. We sweep it, we repair it. One company, no referrals.

Common DuraFlex Chimney Cleaning Problems We Solve in Fontana
- Creosote migration behind the liner in Kaiser-era masonry homes. Fontana’s 1950s and 1960s stucco ranches in 92335 have masonry fireboxes with mortar joints that crack and spall after decades of heat cycling. Soot and creosote work their way behind the DuraFlex liner and sit against the original flue wall. That’s a Level 2 inspection before any sweep, because you can’t safely brush what you can’t see.
- Loose DuraFlex caps and pulled flashing from Santa Ana winds. The seasonal winds that rip through the Cajon Pass and into Fontana shake cap assemblies loose year after year. We routinely find multi-flue caps shifted off their top plate, with flashing screws pulled clean. The result is downdrafts, debris in the firebox, and water staining at the crown.
- Warped or corroded damper blades in idle 1980s-90s prefab fireplaces. Fontana’s newer two-story tract homes in 92336 and 92337 run factory-built DuraFlex fireboxes that sit unused for ten or eleven months a year. The long dry heat bakes damper blades until they bind open or shut. Homeowners report smoky smells in summer, even with no fire, because the damper never fully seats.
- Improper liner clearance from hasty previous installations. We see DuraFlex liners that were dropped in quickly, with insufficient clearance to the masonry wall or a top plate that was never sealed correctly. Smoke spillage follows, and birds and rodents build nests in the gap between the liner and the original flue. Fontana’s uncapped flues are an open invitation.
- Pest and debris intrusion during the long idle season. A fireplace that gets used maybe twelve nights a year accumulates more than creosote. Desert dust, dried vegetation, and bird nests settle in. In Fontana the cleaning call often starts with unsealing wildlife, not sweeping soot.
DuraFlex Service in Fontana: What Local Conditions Mean for Your Equipment
In Fontana’s 92335 ZIP code, the original masonry chimneys on 1950s Kaiser Steel-era homes were frequently built with shallow footings and single-wythe walls. Nelson’s crew has opened enough of them to know the pattern. After repeated Santa Ana wind events, the caps are loose and the flashing is pulled back from the roof line. A DuraFlex liner install on one of these older Fontana homes often requires crown and flashing repair first. If we try to seal a new top plate onto a crumbling crown, the whole assembly fails within a season or two. That’s the kind of thing you only learn by working these specific blocks again and again. On a 1958 stucco ranch near the old Kaiser mill, we pulled a dislodged DuraFlex multi-flue cap off the roof after a windstorm and found the firebox packed with soot, desert dust, and a starling nest—similar to what we handle with our Rialto DuraFlex service. We swept the flue, replaced the warped damper, installed a new cap with fresh flashing, and handed the out-of-state buyer a pre-sale inspection certificate. That’s what a real Fontana DuraFlex cleaning looks like.
DuraFlex Models & Products We Service in Fontana
We work on DuraFlex Pro, DuraFlex Flex, DuraFlex Insulated Liner Kits, and DuraFlex 316L stainless liner systems, including for our Glen Avon DuraFlex service customers. The Pro line typically shows up in Fontana’s factory-built tract homes, while the Insulated Liner Kits are the common retrofit for older masonry fireplaces in 92335. When a DuraFlex component fails, we stock the OEM replacement rather than improvising with whatever’s on a shelf. Caps, top plates, and liner sections come from DuraFlex. Non-critical accessories such as clamps and sealants come from UL-listed aftermarket suppliers when they hold up equally well. We repair when the liner’s integrity is verifiable and replace when corrosion, joint separation, or poor clearance makes repair unsafe.

AfterDuraFlex Service Pricing in Fontana
A standard DuraFlex chimney cleaning in Fontana runs between $189 and $329, varying with roofline access and how much creosote has hardened inside the flue. If the fireplace is a 1950s masonry build with a multi-flue cap that hasn’t been touched in years, the job leans higher because of inspection time and possible cap reseating. A Level 2 camera inspection adds $150 to $300 and is worth every dollar when a home is changing hands or a damper has seized. We give you a written flat-price quote before any tool comes off the truck. Call (866) 520-4943 to schedule something, and the estimate is free.

FAQs – DuraFlex Chimney Cleaning in Fontana
The damper blade has probably warped or corroded from Fontana’s long dry heat and no longer seats fully. That lets air from the flue drift back into the room, carrying old smoke odor. We see this constantly in 92336 and 92337 prefab fireboxes that sit idle most of the year. The fix is a damper replacement, and it’s a repair we handle in the same visit as the sweep. Call (866) 520-4943 and we’ll confirm it on site.
Creosote bakes and hardens during Fontana’s long hot stretches, which means it doesn’t brush out as easily as the softer residue you’d find in a humid coastal chimney. Hardened creosote in a DuraFlex liner often requires rotary cleaning heads and longer dwell time. That’s why a quick sweep skipped for a few years turns into a much bigger job here than in a climate where fires burn more often and keep the creosote soft. Call (866) 520-4943 for an exact quote based on your liner’s condition.
If the separation is at a joint and the surrounding liner sections still show solid 316L stainless wall thickness, we can often repair it with OEM joining bands and reseal the joint properly. A dent that restricts draft or a liner that has rusted through from condensation is a replacement. We make that call with a camera inspection, and we’ll show you the footage. Nothing gets recommended without evidence you can see yourself.
Not by state law, but most Inland Empire inspectors and escrow companies ask for one before closing, especially on the older Kaiser-era Fontana homes where chimneys have been untouched for decades. A Level 2 inspection is the only way to verify liner condition, clearances, and the state of the crown before the title transfers. We provide the inspection and the written report the buyer’s agent wants. Call (866) 520-4943 if you’re in escrow and need it scheduled quickly.
After a Santa Ana event in Fontana, look for water staining on the ceiling near the chimney chase, a cap that seems shifted or missing, or downdraft gusts that push smoke back into the room. You might also hear the cap rattling. Any of these means the assembly has loosened, and in Fontana’s dry season a loose cap also invites birds and rodents. Call us and we’ll get on the roof to check it properly, just as we do for Pedley DuraFlex service calls.
