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 Pomona, CA | Ashwood Chimney Sweep
We clean, inspect, and repair DuraFlex chimney systems across Pomona, including our Chimney Sweep in Pomona. Our work covers DuraFlex Pro, SS, and Flex liners, caps, and components, and we’re an independent service provider, not a manufacturer-authorized agent. What makes our DuraFlex work here different is that we know exactly what Pomona’s older housing stock and Santa Ana wind season do to these systems, because we’ve seen it in hundreds of local homes. Call (833) 805-3229 for a free estimate.
Ashwood Chimney Sweep has worked with DuraFlex products across the Pomona Valley for years, from 1920s bungalows near Lincoln Park to 1960s tract ranches on the east side. We know these liner systems from the inside out. More importantly, we know how Pomona’s specific conditions, the summer heat, the dry winds, the sporadic fireplace use, affect them. DuraFlex sales & service is the kind of work we do every week.
Why Pomona Residents Choose Us for DuraFlex Service
We repair with the same materials professional contractors specify, and DuraFlex is at the top of that list. When you call us for a cleaning in Pomona, you’re not just getting a sweep. You’re getting someone who understands the entire flue system, the liner, the crown, the cap, and how they work together in your specific house.
Norm Castillo, our owner, grew up off Sierra Avenue in Fontana, not far from where the old Kaiser Steel mill used to run. He picked up his trade fundamentals at Chaffey College in Rancho Cucamonga, where he went through their HVAC and building systems program before narrowing his focus entirely to chimneys, flues, and venting systems. He has been working Pomona and the surrounding Inland Empire for close to two decades. When a Pomona homeowner calls about a fireplace that hasn’t been touched in years, or a gas insert venting wrong, Norm is the guy who figures out why.
Clean, inspect, repair, in one call. That’s the whole point. You don’t need three contractors. You need one who can handle the flue, the liner, the crown, and the cap.

Common DuraFlex Chimney Cleaning Problems We Solve in Pomona
- Creosote glazing and third-degree buildup in stainless liners. Pomona’s mild winters mean people light fires sporadically. That’s actually worse for creosote than consistent burning, because each fire partially warms the flue and leaves a new glaze layer. Santa Ana winds pull in dry debris, and before long, a DuraFlex liner that’s structurally sound is carrying a real fire load. We remove it.
- Deteriorating mortar crowns and spalling brick on 1920s and 1930s chimneys. Lincoln Park and downtown Pomona are full of original brick chimneys. Summer heat cycles crack the crown, and once that seal fails, water gets into the liner top and the flue. We inspect the crown every time we clean, because in this part of Pomona service area, crown failure is often the first sign of a bigger problem.
- Liner corrosion at the flue collar and damper area from animal nests and moisture. Pre-1950 Pomona homes commonly have unlined or clay-tile flues. Birds, squirrels, and rats build nests that trap moisture against the liner. Corrosion follows. We find this constantly in homes where a fireplace sat unused for a season or two.
- Failed cap seams and loose flashing on multi-flue caps. Earthquake tremors and thermal expansion work cap seams loose over time. We see DuraFlex multi-flue caps in Pomona with seams that have opened just enough to let rain and animals in. This is a simple fix if caught early, and a liner replacement if ignored.
- Soot accumulation in gas-converted fireplaces venting through unlined flues. Many older Pomona homes converted to gas logs decades ago but never addressed the original flue. Soot and nest debris accumulate, and the first time the system is tested in the fall, it vents poorly. We clean and inspect these before first use.
DuraFlex Service in Pomona: What Local Conditions Mean for Your Equipment
In Pomona’s Lincoln Park historic district, many original 1920s brick chimneys have mortar crowns that crack from summer heat. We often find gas-converted fireplaces still venting through unlined flues that accumulate soot and nest debris. That combination, a cracked crown and a dirty unlined flue, is the single most common red flag we document on pre-1950 Pomona homes. It means the system has been leaking water and exhaust gases for years without anyone noticing. The DuraFlex liner, if one was added at some point, is often doing the structural work while the surrounding masonry crumbles. Pre-fall cleaning and crown sealing here isn’t a recommendation. It’s the difference between a fireplace you can actually use and one that fails inspection. For DuraFlex owners in this district, DuraFlex repair in Claremont follows similar patterns: the liner might be fine, but if the crown isn’t sealed and the cap is compromised, the liner is the only thing standing between the flue and the weather. We treat it that way.
DuraFlex Models & Products We Service in Pomona
We service DuraFlex Pro, DuraFlex SS, DuraFlex Flex, and DuraFlex Cap systems across Pomona and nearby cities, including Covina DuraFlex service. The Pro line is the heavy stainless liner we see most often in full relining jobs, and the SS is common in mid-range installations. Flex is the lighter material we occasionally find in shorter runs and gas-only setups. On the parts side, we use OEM DuraFlex components when available for critical seals and caps. When OEM is discontinued or cost-prohibitive, we recommend quality aftermarket liners and dampers from suppliers like Copperfield and Olympia Chimney, the same trade-only sources certified contractors use. Keeping common components stocked locally means faster turnaround for Pomona homeowners.

AfterDuraFlex Service Pricing in Pomona
Chimney cleaning in Pomona typically runs $195 to $350 depending on the flue condition, liner type, and whether we’re dealing with creosote glaze or just routine soot. Crown repair work, repointing, and sealing usually varies based on the extent of the masonry damage, and cap installation ranges depending on the cap model and whether the flue is single or multi. Your dryer vent is a fire-risk system, not an afterthought, and we quote that work the same way, honestly and specifically. Every estimate starts with a camera inspection, so you see what we see before you approve anything. Call (833) 805-3229 for a free estimate on your Pomona chimney.

FAQs – DuraFlex Chimney Cleaning in Pomona
Annually, no matter how often you use the fireplace. Pomona’s sporadic burn patterns and Santa Ana winds deposit creosote and debris at a rate that builds up surprisingly fast, even with light use. Call (833) 805-3229 to schedule your fall cleaning before the wind season.
Visible corrosion at the flue collar or damper area, holes or separations in the liner walls, or a creosote glaze so thick it has compromised the stainless surface all point to replacement. We show you the camera footage. If the liner is sound, we clean and restore it. If the liner is failing, HeatShield lets us restore it, not just document the problem. Call (833) 805-3229 for an inspection.
Yes. We repoint and seal mortar crowns on historic Pomona chimneys regularly, especially in the Lincoln Park district where summer heat cycles crack the original crown every few years. The repair involves removing loose mortar, rebuilding the crown edge, and sealing against water intrusion. Call (833) 805-3229 to have your crown assessed.
Yes. We install DuraFlex multi-flue and single-flue caps, and we replace failed cap seams on existing units. A proper cap keeps nesting animals and rain out of the flue, which is a bigger deal in Pomona than people realize, given the valley’s squirrel and bird population. Call (833) 805-3229 to get a cap fitted before the next storm.
No. Cleaning addresses fire safety, but seismic compliance requires a structural inspection of the masonry, crown, and liner attachment. Pomona’s older brick chimneys, especially in the 1920s to 1940s stock, often need crown repair, repointing, or partial rebuilds to pass earthquake safety inspections. Ashwood handles the whole flue, not just the easy parts. Call (833) 805-3229 to schedule a full assessment.
