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 | Mayflower Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Fontana, and the work here is different from what a generic sweep truck handles. Most Fontana DuraFlex units are 20 to 40-year-old prefab boxes in tract homes, so a standard “brush the flue” call usually turns into a cap replacement, a Level 2 inspection, or a cracked refractory panel fix once we actually look. Call (877) 819-0285 to book a sweep, and we’ll tell you what your chimney needs in plain language before we touch anything.
We know DuraFlex factory-built fireplaces and venting from the air-cooled wood boxes to direct-vent gas systems. We’re not affiliated with or authorized by the manufacturer. We’re an independent chimney company that stocks and installs named-brand components including DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. For DuraFlex service and the repair side of what a sweep uncovers, see our DuraFlex sales & service page.
Why Fontana Residents Choose Us for DuraFlex Service
Nolan Crisp, our owner, has been working chimneys for going on eighteen years. He came up through the construction and building technology program at Palomar College, where an instructor walked him through draft dynamics and combustion fundamentals before he ever touched a flue. That matters in Fontana because most of the chimneys here aren’t traditional masonry. They’re factory-built metal systems, and diagnosing them takes a different eye than sweeping a brick stack. We’ve worked on enough DuraFlex units across Fontana’s 1980s to 2000s subdivisions, plus Rialto DuraFlex service calls, to know what fails, why it fails, and whether it’s worth fixing.
We also name what we use. When we install a cap or a storm collar on your DuraFlex system, you get a paper trail of exactly what went on your roof. No generic parts from a bottom shelf. If the original DuraFlex component is still available, we match it. If the aftermarket version holds up better to Fontana’s wind, we’ll tell you that too.

Common DuraFlex Chimney Cleaning Problems We Solve in Fontana
- Cracked refractory panels in DuraFlex air-cooled wood fireplaces. Fontana’s long, dry summers leave these fireplaces idle for months. Then winter hits and the box gets short, hot burns. The refractory liner bakes, pops, and cracks. We pull the old panel, match the replacement, and get the firebox sound again.
- Glazed creosote that won’t brush out easily. Creosote forms through the winter, then sits all summer in 90-plus-degree heat. By fall it’s baked hard onto the flue walls. This isn’t the fluffy stuff a standard sweep clears in ten minutes. We use mechanical removal and the right rods for factory-built flues.
- Missing or bent flue caps and rain guards. The Santa Ana winds through the Cajon Pass rip lightweight prefab caps off Fontana roofs regularly. We see it every wind season. A missing cap means dust, debris, and rain get straight into the chase.
- Rusted chase covers with no storm collar. On 1990s subdivision homes in 92336 and 92337, a capped chase without a storm collar is a dead giveaway. Water runs down the flue, rusts the cover, and eventually leaks into the ceiling below.
- Direct-vent gas systems that haven’t been checked in years. DuraTech and DirectVent Pro units still accumulate dust, spider nests, and debris in the venting. The firebox may look fine while the vent above is partially blocked. That’s a carbon monoxide risk, not a cosmetic one.
DuraFlex Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s fireplace stock is dominated by tract homes built during the city’s explosive 1980s to 2000s growth in ZIPs 92335, 92336, and 92337. That means most chimneys here are prefab metal boxes, not masonry. A typical DuraFlex air-cooled unit sitting on a stucco roof off Sierra Avenue is now 25 to 35 years old and has often never had a Level 2 inspection. The dry Santa Ana winds that funnel out of the Cajon Pass work on those lightweight caps and rain guards season after season until something lets go. So when we get a call for “chimney cleaning” in Fontana, the real job is frequently a cap replacement and a chase inspection with the sweep included. That’s not true in Temecula, Glen Avon DuraFlex service areas, or Murrieta the same way. It’s a Fontana pattern, driven by the age of the housing stock and the wind off the pass. If you own a DuraFlex wood fireplace in a north Fontana tract home, the cap may have been gone for two wind seasons before you noticed. By then, the chase is full of baked dust and the rain guard underneath is rusted through.

DuraFlex Models & Products We Service in Fontana
We work on the full range of DuraFlex factory-built systems common in Fontana homes. That includes the DuraTech Direct-Vent Gas Fireplace, the DuraPlus Factory-Built Wood Fireplace, the DuraFlex Air-Cooled Prefab Chimney, and the DirectVent Pro Venting System. Each has its own failure patterns. Air-cooled wood boxes crack refractory panels. Direct-vent gas systems clog at the termination cap. We stock the common parts for these models locally so a cap replacement or panel swap doesn’t mean waiting two weeks on a backorder. If the OEM part is discontinued, we’ll tell you what aftermarket option we’d use and why we trust it.

AfterDuraFlex Service Pricing in Fontana
A DuraFlex chimney sweep in Fontana typically runs $169 to $229 for a standard clean on a factory-built wood fireplace. Adding a Level 2 inspection which we recommend on any prefab unit that hasn’t been looked at in years brings it to $279 to $349. Cap replacement, depending on the size and whether we’re matching an OEM DuraFlex component or a heavier aftermarket cap, runs $185 to $395 installed. Refractory panel replacement falls in the $300 to $600 range depending on the panel. Those numbers shift with access, condition, and what we actually find once the chase is open.

FAQs – DuraFlex Chimney Cleaning in Fontana
Yes. A never-swept prefab is actually the most common call we get in Fontana’s 92336 and 92337 subdivisions. The first visit is a sweep plus a Level 2 inspection, because a 25-year-old factory-built firebox that’s never been opened needs more than a brush through the flue. If anything’s cracked or rusted, we’ll show you photos and explain what can wait and what can’t. Call (877) 819-0285 to schedule the first look.
The Santa Ana winds through the Cajon Pass hit lightweight factory caps harder than they’d ever hit a masonry chimney. If your cap has blown off once, the replacement needs to be sized and secured correctly or it’ll happen again next wind season. We use heavier aftermarket caps when the original DuraFlex part keeps failing, a pattern we also see on Pedley DuraFlex service visits. If it needs doing, we’ll tell you. If it doesn’t, we’ll tell you that too.
You may not know until someone looks. Hairline cracks in refractory panels are often invisible from the living room. Signs include a fireplace that suddenly draws differently, a metallic smell when burning, or visible gaps around the panel edges once the fire’s out. The only way to be certain is a visual inspection with the firebox opened and the flue scoped from above. We do that as part of our Level 2 work.
The venting above the unit. Gas fireplaces that sit idle for years still collect dust, spider webs, and sometimes bird nesting at the termination cap. A blocked direct-vent system can push carbon monoxide back into the house. Before you fire it up again, get the vent run inspected. It’s a quick check and it’s the difference between safe heat and a problem you won’t see coming.
No. Factory-built systems use thinner metal flue walls and specific brush types, so the tools and pressure are different. A masonry chimney can handle aggressive mechanical cleaning. A DuraFlex air-cooled flue can’t. We use the right rods, the right brushes, and a gentler hand on prefab metal. Then we check the panel condition and the cap, because those are where the real problems live in Fontana’s climate.
