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 Fontana, CA | Ashwood Chimney Sweep
We provide independent Glen Avon DuraFlex service and repair across Fontana, from the older tracts south of the 210 up through the newer subdivisions north of Summit Avenue. The thing that sets our DuraFlex work here apart is simple: we’ve scoped enough of these fireplaces in Fontana’s 1950s and 1960s ranch homes to know that most have been swept but never actually inspected. A clean surface doesn’t mean a safe flue, and that’s the gap we close. Call (833) 805-3229 for a free estimate on DuraFlex service that actually documents what’s inside your chimney.
Why Fontana Residents Choose Us for DuraFlex Service
Norm Castillo grew up off Sierra Avenue in Fontana, not far from where the old Kaiser Steel mill used to run, and he’s been working these neighborhoods for close to two decades. He went through the HVAC and building systems program at Chaffey College in Rancho Cucamonga before narrowing his focus entirely to chimneys, flues, and venting. That background matters when you’re looking at a DuraFlex factory-built fireplace that hasn’t been touched since the original owner moved out.
We’re an independent DuraFlex service provider, not a manufacturer-authorized shop. That independence means we follow DuraFlex’s published clearances and component specs without being tied to a warranty program that might push replacement over repair. When your DuraFlex SS or 2100 series firebox has a problem, we tell you what’s actually wrong, what’s fixable, and what genuinely needs replacing. We service Fontana with a repair-first mindset and we source OEM parts when they’re still made, plus quality trade equivalents like HeatShield and Gelco liners when the original part is discontinued. For full DuraFlex sales & service coverage across the region, our team handles everything from cleaning to liner work.

Common DuraFlex Chimney Cleaning Problems We Solve in Fontana
Here’s what we find on DuraFlex units in this city, and why Fontana specifically makes these problems more common:
- Cracked or spalled refractory firebox panels. Fontana summers regularly hit 100°F-plus, then winter cold snaps drive heavy fireplace use. That heat cycling takes a toll on the refractory panels inside DuraFlex fireboxes. By the time a homeowner calls us, the panel is often cracked through, and we have to determine whether it’s a panel replacement or something deeper in the firebox shell.
- Corroded draft hoods and flue collars on older SS units. Where a missing or damaged cap let winter rain into the chase, we see rust and corrosion eating at the draft hood and collar. Fontana’s Santa Ana wind events can lift lightweight caps or shift them enough to let water in, and this is a regular find on DuraFlex SS units that predate the current cap designs.
- Binding or rust-through dampers on wood-burning DuraFlex fireboxes. South Coast AQMD no-burn days mean fireplaces sit idle for long stretches during winter inversions. That idle period lets moisture sit on damper hardware, and we open plenty of DuraFlex dampers that have seized or rusted through since last season.
- Glazed creosote from long idle periods. When a DuraFlex fireplace sits unused through repeated no-burn alerts, the creosote left from the last fire doesn’t get burned off or brushed out. It hardens into a glaze that a standard sweep won’t remove. We use rotary whip systems and chemical treatments to break it down, then camera-inspect to confirm the flue is clean to the listed clearances.
- Water intrusion through cracked crowns on masonry chimneys housing DuraFlex inserts. Many Fontana homes have original 1950s brick chimneys with DuraFlex liner kits or inserts installed later. The crowns on those original chimneys are cracking from decades of Inland Empire heat, and every crack is a path for water to reach the DuraFlex stainless liner. We repair crowns and seal the system before the liner takes damage it doesn’t need.
DuraFlex Service in Fontana: What Local Conditions Mean for Your Equipment
South of the 210 near the old Kaiser Steel site, in the tract neighborhoods built for mill workers in the 1950s, we routinely find chimneys that have been swept but never camera-inspected. Not once in sixty-plus years. The sweep comes out, runs a brush, takes the check, and leaves. Nobody ever scoped the flue. That matters in Fontana specifically because many of those original brick chimneys have cracked crowns from decades of heat cycling, and those cracks let winter rain in during the rare but intense storms. Once water gets into a chimney housing a DuraFlex insert or liner kit, it accelerates corrosion on the stainless components and breaks down the mortar joints. A surface sweep never sees any of this. That’s why we push a Level 2 camera inspection as part of our Pedley DuraFlex service here. On a 1956 ranch home near the old Kaiser Steel site south of the 210, we ran a Level 2 camera inspection on a DuraFlex SS fireplace that had never been scoped in sixty years and found glazed third-degree creosote on the flue walls plus a hairline crack in the crown. We removed the creosote with a rotary whip, applied a crown coating to seal the crack, and installed a new multi-flue cap to keep winter rain out. The homeowner now has a documented, safe flue and a clear Spare the Air use plan. That’s the difference between a sweep and an inspection, and it’s why we don’t do one without the other in Fontana.

AfterDuraFlex Service Pricing in Fontana
DuraFlex chimney cleaning in Fontana typically runs between $180 and $340 depending on the unit’s condition, size, and how long it’s been since the last service. A standard sweep and Level 1 inspection sits at the lower end. Adding a Level 2 camera inspection, glaze removal, or cap replacement moves you up. What drives the cost here is mostly how long the fireplace has been neglected, not the square footage. A clean, well-maintained DuraFlex unit is quick work. A unit with glazed creosote from repeated no-burn idle stretches takes more time and more aggressive removal methods. Our estimates are free, we flatten the quote before we book, and you’ll see a photo report when we’re done. Call (833) 805-3229 for a price on your specific unit.

FAQs – DuraFlex Chimney Cleaning in Fontana
Once a year, regardless of how often you burn. Fontana’s climate hardens creosote during idle stretches and stresses refractory panels through heat cycling, so an annual inspection catches the problems that develop even when the fireplace sits unused through winter.
In most cases, a cracked refractory panel can be replaced without replacing the whole firebox. We replace panels as long as the firebox shell and flue are still sound. If the shell has cracked through, that’s a different conversation, and we’ll show you the camera evidence before you spend a dollar. Call (833) 805-3229 for a real answer on your specific unit.
It means someone ran a brush up the flue and left without ever looking inside with a camera. The original brick chimneys in Fontana’s older tracts often have cracked crowns and glazed creosote that a surface sweep can’t find. We run a Level 2 camera inspection on these systems so you know what’s actually in there.
No-burn alerts don’t stop us from cleaning or inspecting your DuraFlex fireplace. What they do is leave creosote sitting in the flue longer when the fireplace can’t be used. We work around those stretches and schedule Fontana Dryer Vent Cleaning and chimney service when the unit is cool. If you’re in Fontana and unsure about the current AQMD status, we can help you plan around it.
If your current cap is damaged or missing and you have a single flue, we can usually replace it with a matching single-flue cap. A full multi-flue cap makes sense when you have adjacent flues or an irregular chase top that needs full coverage. We’ll measure, show you what fits, and quote it flat before the work starts.
