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 Sunland, CA | Ashwood Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Sunland’s 91040 and 91041 ZIP codes. What makes our DuraFlex work different here is simple: we have been pulling creosote out of these liner systems in Sunland’s earthquake-prone ranch homes since 2008. The 1950s and 60s masonry fireplaces in this foothill community stress DuraFlex liners in ways flatter parts of Los Angeles never see. Call (833) 805-3229 to schedule a DuraFlex inspection or cleaning.
Why Sunland Residents Choose Us for DuraFlex Service
DuraFlex liners are not sold at hardware stores. You cannot walk into a big box retailer and buy an OEM coupling for a DURA-THERM 2000. That means the person servicing your liner needs to know the system, not just carry a brush. We stock OEM DuraFlex components for the repairs Sunland homes actually need: couplings, caps, and connector sections. Norm Castillo, who runs Ashwood Chimney Sweep, has been working these foothill homes for close to two decades. He knows what happens to a stainless liner when the ground shakes and a clay tile flue has already cracked behind it. Our DuraFlex sales & service work is grounded in that local repair history, not a manufacturer training manual.
We are an independent company. DuraFlex does not own us, pay us, or authorize us. What we have is years of hands-on repair data from Sunland’s ranch tracts, where original masonry fireplaces meet modern stainless liners and the combination fails in predictable, fixable ways.

Common DuraFlex Chimney Cleaning Problems We Solve in Sunland
These are the five DuraFlex issues we see most often in Sunland. Each one has a local cause, and each one has a fix that does not require guessing.
- Creosote accumulation in the liner. Sunland’s dry summers bake creosote onto liner walls until it hardens into a glaze. When Santa Ana winds push air down an uncapped flue, that creosote odor comes straight back into the house. We remove it with methods rated for stainless steel, not the wire-wheel approach that scores older liners.
- Liner joint separation after seismic activity. The foothill homes near the 210 freeway sit on ground that shifts. A magnitude 4.0 tremor can open a gap at a DuraFlex coupling joint. We inspect these connections specifically because we know what a shifted joint looks like before it becomes a venting failure.
- Pitting on stainless steel from missing caps. A cap that blew off in a windstorm leaves the liner open to rain and seasonal debris from the Verdugo Mountains. Moisture sitting against stainless steel is how pitting starts, and pitting shortens liner life. We inspect and replace caps as part of every DuraFlex cleaning.
- Damper damage from wind-borne debris. Mid-century fireplaces in Sunland often have original dampers. A good Santa Ana gust can slam debris against the damper plate, leaving it warped or stuck. We repair or replace dampers with parts that meet or exceed OEM specs.
- Obstruction from nesting and ash. The dry brush environment around Sunland pushes birds and rodents into flues for shelter. Combined with ash from frequent winter fires, that is a blocked liner. We clear it and check the liner walls for scratches or damage left behind.
DuraFlex Service in Sunland: What Local Conditions Mean for Your Equipment
There is a pattern we see in Sunland that you will not hear about from a generic chimney company. After any significant earthquake, homeowners in the foothill areas near the 210 freeway notice new cracks in their fireboxes or exterior brick. Then the calls start, because those cracks are usually a sign that the original clay tile flue behind the DuraFlex liner has shifted. A stainless liner can flex, but it cannot stretch. When the surrounding masonry moves, the liner takes the stress at its joints. We have pulled separated DuraFlex sections out of homes in the Sunland area and our DuraFlex service in Tujunga where the homeowner had no idea the chimney had moved at all. That is why we recommend a Level 2 inspection after any tremor strong enough to rattle windows. The chimney might look fine from the outside, but the connection points tell a different story.
Last month, a homeowner in the Sunland-Tujunga foothills near our DuraFlex repair in La Crescenta-Montrose coverage area called us after a tremor to inspect a DuraFlex DURA-THERM 2000 liner in a 1960s ranch home. We found the earthquake had separated a joint in the liner, and creosote had built up heavily because the DuraFlex cap was missing. We replaced the damaged section with an OEM DuraFlex coupling and installed a new multi-flue cap. The system was safe and functional again before the cold nights arrived.
DuraFlex Models & Products We Service in Sunland
We work on the DuraFlex systems installed in Sunland homes over the past two decades. That includes the DuraFlex DURA-THERM 2000 insulated stainless liner, the standard DuraFlex Stainless Steel Flexible Liner, the DURA-TOP multi-flue cap, and the DuraFlex Deluxe Chimney Cap. For critical liner connections and caps, we use OEM DuraFlex components. Compatibility matters at a coupling joint, and a generic part that does not seat properly is a risk we will not take. For standard maintenance items like dampers, we use quality aftermarket parts when they meet or exceed OEM specifications. We stock the common connectors and caps locally, which means most Sunland DuraFlex repairs do not wait on a shipment.

AfterDuraFlex Service Pricing in Sunland
A standard DuraFlex chimney cleaning in Sunland, including a visual inspection and creosote removal, runs between $180 and $340 depending on the liner length and buildup level. A Level 2 inspection, which we recommend after earthquakes or when liner damage is suspected, adds camera work and runs higher. Cap replacement typically falls between $150 and $450 depending on whether you need a standard DuraFlex cap or a DURA-TOP multi-flue cap sized for your chimney. Liner section repairs are quoted after we see the damage, because until a camera is in the flue, any number is a guess. We provide a free estimate before any work begins. Call (833) 805-3229 and we will set a time to look.

FAQs – DuraFlex Chimney Cleaning in Sunland
Look for new cracks in your firebox or exterior brick, which are the most common signs that the surrounding masonry shifted during a tremor. You might also hear a rattle when wind hits the chimney, or smell smoke in the house during your next fire. The fastest way to know is a Level 2 camera inspection, which shows whether a DuraFlex joint has separated. Call (833) 805-3229 to schedule one.
Stop using the fireplace until the cap is replaced. An open flue lets debris, rain, and animals inside, and the next Santa Ana event will push ash and creosote odor straight into the house. We keep DuraFlex caps and DURA-TOP multi-flue caps in stock for Sunland homes, so replacement usually happens within a few days of your call.
Stainless steel liners require brushes and tools rated for metal flues, not the aggressive wire-wheel or chemical treatments that can scratch older liners or void warranties. We match the method to the creosote stage: rotary brushes for glaze, standard brushes for soot. The goal is clean stainless, not scratched steel.
Annually, with a bit of extra urgency if you live in the foothill tracts near the 210 freeway. Sunland’s earthquake activity and Santa Ana winds add stress to liners that homes in flat parts of LA and our Burbank DuraFlex service area do not experience. An annual cleaning plus a visual inspection catches joint separation and cap damage before they become venting failures. Call (833) 805-3229 for a free estimate.
Small dents that do not affect the cap’s fit or airflow can often stay, but anything that changes how the cap seats or blocks the spark arrestor needs replacement. We will tell you plainly which category your cap falls into. We stock replacements for the most common DuraFlex cap sizes in Sunland, so if you do need a new one, you will not wait long.
