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 San Marino, CA | Imperial Chimney
We provide independent DuraFlex chimney cleaning and inspection across San Marino, including both 91108 and 91118, plus DuraFlex repair in Alhambra. The one thing that separates our DuraFlex work here is that we’re almost always servicing a stainless liner inside a chimney that’s been standing since the 1920s, and those original clay tiles rarely survive that long without cracking. Imperial Chimney has the camera gear, the OEM parts, and the patience to show you exactly what’s happening between the liner and the old masonry. Call (866) 253-3809 to schedule a sweep or Level 2 inspection in San Marino.
Why San Marino Residents Choose Us for DuraFlex Service
DuraFlex relines are built to last, but they don’t exist in a vacuum. In San Marino they’re usually installed inside chimneys that were laid before World War II, and the interface between old clay and new stainless is where problems hide. Our techs have spent years working specifically with DuraFlex stainless flexible relining systems, from their multi-fuel and insulated kits to the component connections that tend to fail in older masonry chimneys. We’re an independent shop with deep product familiarity, not a DuraFlex dealer, so our recommendations come from what we actually find in San Marino flues. Noel Carrasco, our owner, trained at Los Angeles Trade-Technical College and has been cleaning and inspecting chimneys across the LA basin for going on two decades. If it’s in the flue, we’ll tell you straight – no upsell, no vague “concerns.”

Common DuraFlex Chimney Cleaning Problems We Solve in San Marino
Most San Marino homes with DuraFlex liners fall into a pattern. The liner was installed well, the fireplace works, and then years of dry-season heat cycling and minor seismic movement start working on the connections. What we find during a routine cleaning:
- Separated top plate connections. A flexible liner installed years ago in a 1920s clay-tile flue often shifts at the top plate, letting creosote and moisture bypass the liner entirely. In San Marino, where chimneys sit unused for eight months a year, that bypassed soot hardens and becomes genuinely difficult to remove.
- Insulation wrap degradation. We regularly see insulation wrap slipping off an insulated DuraFlex liner after long dry-season heat cycling. Once the stainless is exposed, the liner no longer holds the UL rating it was installed for – and in a San Marino estate fireplace that may burn hot for a few weeks straight, that matters.
- Clay tile failure behind the reline. Cracked or separated clay tiles around a DuraFlex reline are common in San Marino after decades of minor seismic activity. Soot lodges behind the liner where a standard sweep can’t reach it, and the homeowner never sees it without a camera inspection.
- Loose connection fittings at dampers and tees. The fittings that should seal a DuraFlex system at the appliance collar loosen over time. Smoke pushes back into the firebox, and the homeowner assumes the chimney is dirty when the real problem is a mechanical connection.
- Wind-damaged caps after Santa Ana events. San Marino’s Santa Ana winds can knock a cap loose or off completely. A missing cap lets debris and birds into the DuraFlex liner, and the damage compounds fast.
DuraFlex Service in San Marino: What Local Conditions Mean for Your Equipment
Here’s what makes San Marino different from Pasadena, Arcadia, or anywhere else we work. In San Marino’s historic estates the DuraFlex reline is often the newest thing in a nearly hundred-year-old chimney. A Level 2 inspection here isn’t really a check on the liner itself – it’s a check on how that stainless liner sits inside original 1920s clay tiles that decades of minor seismic movement have cracked. That combination simply doesn’t exist in neighboring cities with newer tract housing. On a Period Revival estate off Lorain Road in the 91108 ZIP, our crew pulled a Level 2 camera through an older DuraFlex insulated liner and found the wrap had slipped near the top plate, leaving bare stainless while soot packed the gap between liner and a cracked clay tile. We cleaned the flue, re-secured and re-wrapped the DuraFlex liner, fitted a proper top plate and cap, and documented the cracked tile so the homeowner had a clear record. That’s what a San Marino DuraFlex cleaning looks like when it’s done properly. For more on how we approach this brand across the region, see our DuraFlex sales & service page.
DuraFlex Models & Products We Service in San Marino
We work on all the major DuraFlex product lines installed in San Marino homes. That includes the DuraFlex Stainless Steel Flexible Chimney Liner in multi-fuel configuration, the DuraFlex Insulated Flexible Liner Kit, the DuraFlex Pro Flexible Liner, and the full set of DuraFlex Reline Components – tees, caps, and top plates. When we replace a liner, tee, top plate, or cap, we use DuraFlex OEM components so the system keeps its listed configuration. We’ll use quality aftermarket parts only where they meet or exceed the original spec. When a DuraFlex liner is sound we clean and document it rather than push a replacement. When the liner itself is compromised we say so plainly and show you the camera footage.

AfterDuraFlex Service Pricing in San Marino
DuraFlex chimney cleaning in San Marino typically runs between $180 and $340 depending on the condition of the liner and the level of inspection needed. A Level 2 camera inspection adds cost because of the equipment and documentation involved, but it’s the only way to actually see what’s happening behind a DuraFlex reline in an older chimney. What drives the price: whether the liner has been cleaned recently, whether the wrap has degraded, and whether we need to pull and re-secure any components. Our estimates are free, and we’ll always show you the camera findings before recommending any work. Call (866) 253-3809 for an exact quote on your San Marino chimney.

FAQs – DuraFlex Chimney Cleaning in San Marino
Yes and no. The liner doesn’t eliminate creosote buildup – it just contains it better. Given San Marino’s pattern of light seasonal use, we still recommend an annual sweep for wood-burning fireplaces, especially if you burn during the few cold weeks when the whole city lights up at once. Call (866) 253-3809 if it’s been more than a year since your last cleaning.
Because the liner isn’t the only surface in the flue. In San Marino’s older chimneys, cracked original clay tiles behind the reline create pockets where soot accumulates outside the liner itself. A basic sweep won’t reach it. Only a camera inspection will show it, which is why we treat every DuraFlex cleaning in the 91108 and 91118 ZIP codes as an opportunity to check what’s behind the stainless.
Yes. We’re careful with original masonry, firebox surrounds, and decorative elements, which is part of why owners of landmarked and historically reviewed San Marino properties call us. The cleaning itself doesn’t disturb the exterior structure, and if the liner or cap needs work, we document everything clearly for any design-review process.
Yes, DuraFlex relines are listed for wood-burning applications when installed to spec. The issue in San Marino is rarely the liner’s rating – it’s the condition of the original clay tiles around it and the integrity of the connection points. We verify all of that during a cleaning.
Almost certainly not. A loose cap is usually a simple re-securing job with a proper top plate and hardware. We’d only recommend system replacement if the liner itself is compromised. Call (866) 253-3809 and we’ll take a look before recommending anything.
