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 South Pasadena, CA | Sherwood Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and repair in Alhambra and across South Pasadena, including both 91030 and 91031. What makes our DuraFlex work different here is simple: we understand how these liner systems behave inside the city’s 1900s-1920s brick chimneys, many of which were never designed for modern stainless liners. If you need a sweep, a liner assessment, or cap work on a DuraFlex system, call (833) 589-8498 for a free estimate.
Sherwood Chimney Sweep is not a DuraFlex distributor and we’re not authorized by the manufacturer. We’re an independent service company that works on these systems every week. That independence means we tell you what your liner actually needs, not what a brand rep would prefer to sell you. We stock DuraFlex-compatible fittings and components, read the product literature front to back, and adapt every installation to the realities of South Pasadena service area construction rather than assuming a showroom-new chase. Noel Carver, our owner, grew up not far from Garfield Park and has spent over twenty years looking up at flues and dampers across the San Gabriel Valley. He’s the one who set our rule: nothing gets recommended without camera evidence the homeowner can see for themselves.
Why South Pasadena Residents Choose Us for DuraFlex Service
Most chimney companies in the San Gabriel Valley clean a flue, hand you a bill, and leave. We work differently because South Pasadena’s housing stock demands it. The Craftsman bungalows and Spanish Colonial Revival homes built between 1900 and 1930 often have original brick chimneys with no modern flue liner at all, or with a DuraFlex liner that was retrofitted into a space never meant for it. You need a technician who can read that situation accurately.
Our crews work with DuraFlex sales & service systems regularly enough to know the failure patterns: torn insulation wrap, separated joints, corrosion on smooth-wall interiors. We use DuraFlex OEM liner components, top plates, and caps where the existing system matches, and we specify quality aftermarket stainless fittings only when an OEM part is unavailable for a discontinued profile. That’s the straight answer on parts, and it’s the same answer we give on every job. We’ll repair a sound liner with new components and re-insulation before recommending replacement, because replacing a liner in a preserved South Pasadena home is harder and more expensive than in a modern house. Restore before you replace, whenever the liner is structurally sound.

Common DuraFlex Chimney Cleaning Problems We Solve in South Pasadena
- Insulation wrap failures in tight original flues. DuraFlex flexible liners rely on an insulation wrap to maintain clearance protection. In South Pasadena’s 1900s brick chimneys, that wrap often gets nicked or compressed during installation because the flue passage is narrow and irregular. The result is hot spots and reduced protection. We inspect for this during every Level 2 inspection.
- Joint separation in short, offset flues. Many of the 1920s bungalows in South Pasadena have flues that were originally sized for coal, then converted to wood. When a flexible DuraFlex liner gets pushed through that undersized, offset passage, joints can separate or fasteners can back out over time, especially behind original plaster walls in attic spaces where nobody sees the damage until a smell or draft gives it away.
- Creosote buildup from sporadic burning. South Pasadena’s hot, dry summers and mild winters mean most residents burn fires only a few weeks in December and January. Without the self-cleaning effect of regular hot burns, creosote accumulates slowly over years. A chimney that hasn’t been swept in five seasons may look fine from the hearth but be carrying a heavy coating on the liner walls.
- Smooth-wall corrosion and pitting. DuraFlex SW (smooth-wall) liners are efficient, but they’re not immune to the effects of creosote and moisture sitting on the interior between short burn seasons. If your fireplace gets used a handful of times each winter and then sits damp from coastal air creeping into the San Gabriel Valley, the liner interior can pit and corrode faster than it would in a colder climate with more regular use.
- Top-plate and cap failures from Santa Ana winds. The dry Santa Ana winds that sweep through South Pasadena carry grit and debris. Cap terminations and top plates take the brunt of that, and we regularly see them pulled loose or rusted out where wind-driven material blasts the cap and the liner’s top connection. A cap that’s shifted even a quarter inch is an opening for water and animals.
DuraFlex Service in South Pasadena: What Local Conditions Mean for Your Equipment
South Pasadena’s preservation ordinance is the single biggest factor shaping how DuraFlex service works here, and it’s something no generic chimney page will tell you. The city restricts exterior modifications on its historic 1900s-1920s homes, which means you can’t just bolt on a modern multi-flue cap or replace a crown with a bigger footprint without running into permit scrutiny. For DuraFlex owners, that changes how liner terminations and cap work get done. We often have to reuse or match the existing exterior crown and cap footprint, selecting a low-profile cap that fits the original dimensions rather than adding a visible new assembly. Walking the Orange Grove Avenue corridor, you see this in practice: chimneys that look original from the street but have been relined and recapped on the inside. On one 1920s bungalow off that corridor, our tech found a DuraFlex flexible liner that had been pushed through a coal-era flue and hidden behind original plaster in the attic. The insulation wrap was torn and the joint fasteners were backing out. We pulled and re-seated that liner with fresh wrap and OEM fittings, cleaned heavy creosote off the smooth wall, and finished with a low-profile cap that fit the existing crown without changing the exterior look. That’s the job done the South Pasadena way.
A clean chimney doesn’t announce itself. That’s the point.

AfterDuraFlex Service Pricing in South Pasadena
DuraFlex chimney cleaning and inspection in South Pasadena typically falls between $180 and $340, depending on liner type, access, and how much creosote has accumulated. Several factors drive the cost: whether your liner runs through a straight modern flue or a short, offset coal-era passage; whether the cap or top plate needs attention; and whether we’re doing a standard sweep or a Level 2 inspection with camera documentation. Every quote is flat-price and agreed before we book, and the camera inspection with photo report is included. We never quote repair work without showing you the footage. Call (833) 589-8498 for an exact price on your specific setup.

FAQs – DuraFlex Chimney Cleaning in South Pasadena
Yes, in most cases. The key is avoiding exterior modifications. If the liner work can be done from the inside, through the existing flue opening, and the cap or crown footprint stays unchanged, it typically falls outside the preservation review trigger. We assess this early in the job because it shapes everything downstream. Call (833) 589-8498 and we’ll tell you which route applies to your home.
Often yes, but only with the right installation approach. The undersized coal-era flue means a flexible liner has to navigate offsets that a rigid liner can’t. DuraFlex Pro flexible systems are designed for that kind of retrofit, but the insulation wrap and joint fasteners need extra attention because they’re the components most likely to fail in a tight, uneven passage. We’ve done this exact job on multiple Orange Grove Avenue homes.
That odor usually comes from creosote that has saturated the liner wall and is releasing volatiles when the flue warms slightly or when air pressure changes. A visual check from the hearth won’t catch it. You need a camera inspection to see the actual liner surface, and in South Pasadena’s sporadic burn pattern, this is one of the most common complaints we hear. Book a sweep and camera look and we’ll show you exactly what’s going on. Estimates are free at (833) 589-8498.
Yes, when the liner wall is structurally sound. We repair torn insulation wrap, re-seat separated joints, replace failed fasteners, and install new top plates and caps. Replacement only comes up if the liner itself has corroded through, split, or lost its structural integrity. We’ll always show you the camera evidence before recommending either path.
We do. Those ranch homes, mostly on the south side of the city, often have original clay-tile flues that are prone to spalling, and some have had DuraFlex liners added as a retrofit. Whether it’s a clay tile that’s deteriorating or a DuraFlex liner that’s underperforming, the same service applies: inspect, document, and repair before replacing. Call (833) 589-8498 for a free estimate.
