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 Burbank, CA | Ashwood Chimney Sweep
We provide independent DuraFlex specialists for chimney cleaning, inspection, and repair across Burbank’s 91523, 91526, 91501, and 91502 ZIP codes. The thing that makes our DuraFlex work different here is simple: Burbank’s 1920s-1950s bungalows were relined in waves during the 1990s and 2000s, and those liners are now hitting the age where top plates loosen, caps clog, and creosote hardens in flues nobody has looked at in years. We’re not manufacturer-affiliated, but we work on these systems weekly and know exactly what fails on them in this city. Call (833) 805-3229 for a free estimate.
Why Burbank Residents Choose Us for DuraFlex Service
Ashwood Chimney Sweep has been working Burbank’s older housing stock long enough to recognize the patterns. When we show up to a Spanish Colonial Revival in the Rancho district or a bungalow off Magnolia, we already know what we’re likely to find: a DuraFlex liner dropped into cracked clay tile, a top plate that’s shifted, and a cap that’s been collecting palm debris since the last Santa Ana. Norm Castillo, our owner, built his trade fundamentals in HVAC and building systems before narrowing to chimneys and venting exclusively, and he’s spent close to two decades in Southern California’s older neighborhoods, including providing North Hollywood DuraFlex service. That means we don’t just sweep the flue and leave. We check the liner, the terminations, the cap, and the draft, because a clean flue connected to a failing top plate is still a problem.
We stock DuraFlex-compatible stainless components and top plates locally so Burbank callbacks don’t stall waiting on parts. When an OEM part is discontinued, we match aftermarket hardware to the existing liner spec rather than improvising. And we’re a full-service shop: chimney sweep, chimney repair, and dryer vent cleaning under one call. If your flue needs more than a cleaning, you’re already talking to the crew that does the repair.

Common DuraFlex Chimney Cleaning Problems We Solve in Burbank
- Loose top plates on 1990s relines. Burbank’s dry-season heat expansion and the occasional winter rain work on old crowns and mortar, and a top plate that was sealed twenty-five years ago is often no longer sealed at all. Santa Ana winds push debris under the gap and into the flue.
- Hard-cured creosote in gas-converted flues. Many Burbank bungalows switched from wood to gas log sets, but the DuraFlex liner stayed. Soot and creosote that built up during the wood-burning years cure hard in the dry heat, and it doesn’t just burn off. It needs mechanical removal.
- Kinked or crimped liner sections at offsets. Older Burbank chimneys have tight offsets, and installers sometimes dropped the flexible liner too fast. A kink creates a soot trap and a draft restriction, and it shows up as smoke backing into the room on windy days.
- Wildlife and debris-clogged caps. Uncapped or poorly capped flues in Burbank collect bird and squirrel nests during the dry months, along with palm fronds and windblown debris. A clogged cap forces combustion gases back into the house.
- Deteriorated insulation wrap on older relines. Some 1990s-2000s DuraFlex installations used insulation wrap that’s now sagging or gone. Without it, condensation builds in the flue, especially on cool winter mornings, and that moisture accelerates corrosion.
DuraFlex Service in Burbank: What Local Conditions Mean for Your Equipment
There’s a detail about Burbank that most chimney companies from outside the Valley miss: the lot lines are tight, and the rooflines are crowded. Magnolia Park and the Rancho district were built with narrow lots, then second-story additions went up over the decades, and mature trees filled in. When a DuraFlex reline was installed in the 1990s or 2000s, the installer sometimes chose a short, low-profile top plate just to get it to fit under an overhang or squeeze past a tree branch. That low-profile cap now catches palm debris and gives squirrels a place to nest. Roofline access across these cramped quarters is a significant part of the job in Burbank, not an afterthought. We carry extension ladders and equipment sized to get up there safely without trampling your neighbor’s tile roof or hanging off a second-story gutter.
A field example from our own work: on a Magnolia Park bungalow off West Clark Avenue, our tech found a 1990s DuraFlex single-wall liner whose top plate had pulled loose from a cracked crown. A squirrel nest was packed against the cap, and soot was falling into the firebox of a gas-converted fireplace. We cleared the flue, reset and sealed the top plate, and installed a multi-flue cap sized to the chimney, then confirmed draft on a Level 2 follow-up.
DuraFlex Models & Products We Service in Burbank
We service the full range of DuraFlex flexible liner systems, including single-wall (SW) stainless relining kits, double-wall insulated Pro liners, ovalized liners for tight masonry flues, and the round-to-oval adapters, top plates, and caps used in reline retrofits. If your Burbank home still has the original paperwork, we’ll match the liner spec to the job. If the paperwork’s long gone, we identify the liner by size, profile, and connection type on site. Our parts approach is straightforward: where DuraFlex OEM components are still available, we use them. Where they’re discontinued, we use quality aftermarket stainless hardware matched to the existing spec, never a mismatched part forced to fit.

AfterDuraFlex Service Pricing in Burbank
A DuraFlex chimney cleaning in Burbank typically falls between $189 and $349, depending on flue condition, access difficulty, and whether we’re also addressing the cap and top plate. A Level 2 inspection, which we recommend for any liner that hasn’t been seen in years, adds cost but gives us camera evidence of what’s actually happening inside the flue, not a guess. Cap installation or replacement runs $95 to $325 depending on size and roofline access. Creosote removal for heavily built-up wood-burning flues lands between $150 and $400. We give you a flat-price quote before any work starts, and the estimate is free. Call (833) 805-3229 and we’ll walk through what your Burbank chimney actually needs.

FAQs – DuraFlex Chimney Cleaning in Burbank
Yes, and here’s why. A liner that’s twenty to thirty years old has been through hundreds of heat cycles, several earthquake seasons, and years of Santa Ana winds prying at the top plate. We run a camera through the flue before we put brushes in it, because if the liner has separated from the top plate or kinked at an offset, cleaning it without knowing can hide a problem rather than fix one. The Level 2 inspection shows us exactly what we’re working with, and we’ll show you the footage. Call (833) 805-3229 to book one.
Gas fireplaces don’t produce soot the way wood fires do, so if you’re seeing black buildup or smelling something stale, the most likely culprit is old creosote from the wood-burning years that’s hardened inside the DuraFlex liner. Gas exhaust doesn’t burn it off; it just sits there and gets sticky in the dry heat. The other common cause is a clogged cap or a nest in the flue pushing combustion gases back into the house. We remove the creosote, clear the obstruction, and confirm draft so the smell doesn’t come back. Call to schedule a cleaning and inspection.
In Burbank, yes. The Valley’s dry season creates ideal nesting conditions for squirrels and birds, and uncapped or under-capped flues get packed with debris. A multi-flue cap covers the entire crown, protects the top plate, and keeps wildlife out regardless of which flue is active. If your roof is crowded with overhangs or tree canopy, a low-profile cap may be a better fit, but either way, an exposed top plate on an older reline is asking for trouble. We’ll show you what we find and recommend what fits your chimney. Call (833) 805-3229 for a free estimate.
A kink in a flexible liner cannot be straightened back to full function. The stainless has creased, the internal profile is deformed, and the restriction to draft is permanent. What we can sometimes do is re-terminate the liner if the damage is at the top connection, or replace a section if the rest of the liner is sound. When the liner is kinked mid-run or corroded through, we’ll tell you plainly that a replacement is the honest fix, not patchwork. You’ll see the camera footage before deciding.
Once a year if you burn wood regularly, and before burning season if you only light the fireplace a few times each winter. Burbank’s long dry season cures creosote until it’s hard and highly flammable, so even light use can build up material that shouldn’t be there. If you’ve converted to gas, the sweep interval can stretch, but an annual inspection still catches cap and top-plate problems before they become water or wildlife issues. Call (833) 805-3229 and we’ll get you on the schedule.
