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 | San Bernardino Chimney Sweep
DuraFlex chimney cleaning in Pomona means servicing stainless liner systems that often fail from disuse and Santa Ana wind exposure, not from heavy creosote buildup. We’re an independent DuraFlex service provider covering all Pomona ZIP codes, and the work here is different because most fireplaces sit idle for years while wind and nesting animals do the damage. If your DuraFlex liner hasn’t been inspected in more than two seasons, call (877) 516-7159 for a free estimate.
We’re San Bernardino Chimney Sweep, and we’ve spent years working on DuraFlex sales & service across the Inland Empire. Our Pomona service area includes the older bungalow core where DuraFlex liners age differently than they do in newer tract housing. Being independent means we repair what’s sound and replace only what’s genuinely failed.
Why Pomona Residents Choose Us for DuraFlex Service
We know how DuraFlex stainless liners, tees, and top plates actually behave in inland Southern California. The thermal cycling here isn’t dramatic, but the wind loading is. Allen Prescott, our owner, grew up near the Kendall Drive corridor in San Bernardino and has spent the better part of three decades working on chimneys and fireplaces across the Inland Empire. He learned HVAC and building systems at San Bernardino Valley College before narrowing his focus to chimney maintenance and venting safety, and he built this company on straight talk: whether you need La Verne DuraFlex service or work in Pomona, we tell you exactly what we found in your flue, why it matters, and what needs doing versus what can wait.
Pomona homeowners call us because we stock OEM DuraFlex components, not generic substitutes. When a top plate has lifted or a tee connection has separated, matching the original liner sections and terminations is what keeps the system from failing again at the joint. We’re a specialist, not a generalist. Chimney sweeping, chimney repair, and dryer vent cleaning are what we do. If we find damage during a sweep, we can fix it on the spot. You won’t need to call a second company.

Common DuraFlex Chimney Cleaning Problems We Solve in Pomona
These are the failure patterns we see most often when servicing DuraFlex systems in Pomona homes:
- Uninsulated liners corroding in citrus-era bungalows: DuraFlex SW and Pro liners installed without an insulated wrap in unlined 1900s-1950s brick or river-rock chimneys across 91766 and 91767 develop corrosion pitting and joint separation at the tee. These flues sit damp and idle for years, and the moisture does the damage creosote never gets a chance to.
- Top plates and caps worked loose by Santa Ana winds: We routinely find DuraFlex stainless cap assemblies lifted or shifted on Pomona chimneys. Wind gets under the cap edge, loosens the fasteners, and lets rain enter the flue. That water then drives the dry-rot and mortar deterioration we find on exterior masonry stacks.
- Tees and elbows packed with nesting material: Desert wood rats, scrub jays, and squirrels plug the tee and elbow connections on DuraFlex liners in bungalow chimneys that haven’t been used in a decade. The nest becomes a moisture trap against the liner and blocks draft when the homeowner finally lights a fire.
- Seized dampers hiding liner shifts: On DuraFlex-equipped wood-burning fireplaces, we find damper and firebox components rusted or seized from disuse. The homeowner never notices the liner has shifted until we run a Level 2 camera and find the joint gap.
- Mixed-brand terminations leaking: Some past installs in Pomona used aftermarket caps or top plates that don’t fit DuraFlex liner dimensions properly. The mismatched termination is where wind-driven rain gets in and where the liner starts to corrode from the top down.
DuraFlex Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the pattern a generic DuraFlex page won’t tell you. Pomona sits in a former citrus-and-agricultural belt where wood-burning fireplaces were nearly universal in the early-20th-century bungalows and craftsman homes. But the inland heat means most are lit only a handful of nights a year. The result is that a DuraFlex liner in Pomona often goes years between fires, and it fails from damp, nesting, and wind intrusion rather than from creosote volume. The chimney isn’t being used enough to stay dry, and the Santa Ana winds do the rest. A technician working the older core near downtown Pomona in 91766 sees a different failure profile than someone working a heating-dependent mountain community fifteen miles north, or a crew handling DuraFlex repair in Walnut. Here, we’re pulling nests out of tees and reseating top plates far more often than we’re removing thick creosote glaze.
This is why we push the Level 2 camera inspection so hard for Pomona DuraFlex owners. The liner looks fine from the firebox, the chimney hasn’t been used, and the homeowner assumes nothing’s wrong. But moisture and wind work on stainless even when there’s no fire. “A clean flue isn’t a luxury – it’s just how you keep the fire where it belongs.” That’s the line Allen uses when a homeowner asks why an unused chimney needs service.
DuraFlex Models & Products We Service in Pomona
We service the full residential DuraFlex line: the SW single-wall flexible stainless relining kit, the DuraFlex Pro flexible stainless chimney liner, the Insulated flexible liner kit, and DuraFlex stainless steel chimney caps and top-plate assemblies. When a liner section, tee, top plate, or cap needs replacement, we match OEM DuraFlex components wherever the original system is still serviceable. Mixing brands at the termination and tee is where leaks and wind failures start, so we keep the common DuraFlex fittings and terminations stocked for fast turnaround across Pomona. Where a liner is sound but a cap, crown, or flashing has failed, we repair rather than push a full reline.

What drives the cost on a Pomona DuraFlex job is access, how much nesting material has to be cleared, and whether the liner itself is sound. A wind-loosened cap on a single-story bungalow is a quick fix; a corroded tee buried under a decade of animal nest is a different job. Every estimate starts with a free phone conversation and, where needed, an on-site look. We don’t recommend work without camera evidence you can see yourself. Call (877) 516-7159 and we’ll give you a straight number.

FAQs – DuraFlex Chimney Cleaning in Pomona
An unused liner still gets attacked by moisture, wind, and animals. In Pomona’s citrus-era bungalows, we find rust tracking down stainless from rain entry at loose top plates, corrosion pitting from damp flues, and nests plugging tees. The Level 2 camera shows you exactly what’s inside before you light the first fire of the season. Call (877) 516-7159 to schedule one.
Yes. We routinely find DuraFlex cap assemblies lifted or loosened after a strong Santa Ana event in Pomona. Wind gets under the cap edge, works the fasteners loose, and lets rain into the flue. An annual visual check of the termination before fire season is the cheap insurance. Call (877) 516-7159 and we’ll take a look.
You need a cap more than most. A rarely used Pomona chimney is an open invitation to desert wood rats, scrub jays, and squirrels, and the nesting material they bring becomes a moisture trap against your DuraFlex liner. A properly fitted stainless cap also keeps Santa Ana wind from working rain into the flue. Call (877) 516-7159 for a cap fit check.
Yes. The Level 2 camera inspection focuses on the liner, but we’re also looking at the masonry condition around it. On Pomona’s post-war stucco chimneys, we check for spalling brick, failing mortar joints, and moisture staining that signals the stucco isn’t shedding water anymore. If the masonry is failing, it’s better to know before it compromises the liner run. Call (877) 516-7159 for a full inspection.
Sometimes, yes. If the stainless is sound except for one failed section or joint, we can replace that run with OEM DuraFlex components and leave the rest in place. If the liner is pitted through in multiple spots or the joints have separated along the full length, a full reline is the honest call, and we’ll show you the camera footage either way. Call (877) 516-7159 for a free estimate.
