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 Northridge, CA | Firebrick Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Northridge, covering every ZIP from 91324 to 91330. Most companies will sweep the flue and call it done. What makes our DuraFlex work different here is that we’re also looking for the earthquake damage hiding behind the liner, because in Northridge, that’s not a rare find. It’s the norm. Call us at (866) 520-4943 and we’ll tell you exactly what’s going on inside your chimney before we touch a brush to it.
We’re Firebrick Chimney Sweep, and we’ve spent years working on DuraFlex sales & service systems in the San Fernando Valley. Northridge homes, in particular, have a way of testing these liners harder than most. Nelson Quijada, our owner, grew up off Cahuenga Boulevard in Hollywood and has spent two decades on chimneys in the same hillside homes and mid-century bungalows he passed every day as a kid. He’ll tell you straight what needs fixing and what can wait. Nothing more.
Why Northridge Residents Choose Us for DuraFlex Service
DuraFlex liners are good equipment, but only if they’re installed right and inspected by someone who understands what they’re looking at. We do. The homes across Northridge and nearby North Hills DuraFlex service areas, especially the postwar ranchers built between 1950 and 1975, often have original clay tile flues that were never designed for a stainless liner. When we open one up, we know what proper fit looks like versus a liner that was jammed in and called good.
We stock genuine DuraFlex caps, top plates, and liner components when available. For older or discontinued systems, we use aftermarket parts that meet or exceed original specs, and we’ll tell you which one you’re getting and why. We never push a full reline when a crown repair or cap replacement will safely solve the problem. Chimney work is all we do, and that depth shows in every inspection.

Common DuraFlex Chimney Cleaning Problems We Solve in Northridge
- Flue tile offsets from the 1994 earthquake. The epicenter was directly under this district. We routinely find shifted clay tiles behind DuraFlex liners in ranch homes near the old Northridge Mall and along Reseda Boulevard. Those offsets create gaps where creosote and moisture collect, even when the liner itself looks fine from the top.
- Cracked crowns letting water past the top plate. Northridge’s dry summers preserve mortar, but winter rains and Santa Ana wind events find every weakness. A failed crown lets water run down around the DuraFlex cap and top plate, and by the time you see staining inside, the damage is already done.
- Condensate corrosion in early stainless liners. Many Northridge homes have under-height flues that draft poorly on still valley nights. Gas and wood appliances push moist exhaust through, and cheaper alloy liners from early DuraFlex installs corrode at the seams. We see joint separation in these regularly.
- Improperly sized or uninsulated liners. Original clay tile flues in Northridge ranchers are often irregular. A liner that’s too narrow or installed without an insulation wrap will cause smoke-back and creosote buildup that looks like a blockage. It’s actually a fit issue, and cleaning alone won’t fix it.
- Debris intrusion through failed DuraFlex caps. Santa Ana winds in late fall drive leaves, twigs, and bird nests into chimneys with damaged or missing caps. We find this constantly in Northridge, especially after the first big wind event of the season.
DuraFlex Service in Northridge: What Local Conditions Mean for Your Equipment
Here’s the thing most Northridge homeowners don’t connect: the 1994 earthquake didn’t just crack driveways and topple chimneys. It shifted flue tiles inside thousands of chimneys that are still standing. Inspectors in 91324 and 91325 find tile offsets and hairline fractures that homeowners never associated with quake damage, especially in the single-story ranchers near the old Northridge Mall and the Reseda Boulevard corridor. Those shifts misalign liner sections, open gaps, and let creosote build up in places a standard sweep can’t reach. If your DuraFlex liner was installed before 1994 and you still get smoke-back on cold winter evenings, there’s a good chance the liner shifted with the tile behind it. Draft problems in Northridge are often structural, not just a dirty flue. That’s why we don’t just sweep DuraFlex systems here. We check alignment, verify the top plate seal, and look for the signs that quake settling left behind.
DuraFlex Models & Products We Service in Northridge
We work on the full range of DuraFlex equipment found in Northridge homes and provide Encino DuraFlex service as well. That includes DuraFlex 316L stainless flexible relining kits, the kind commonly installed to reline original masonry flues in 1950s to 70s ranch houses. We also service DuraFlex Pro Series direct-vent and B-vent prefab fireplace components, DuraFlex Sure-Tite adjustable chimney caps and multi-flue caps, and flexible liner insulation wraps used in retrofit installations.
When we stock DuraFlex replacement caps, top plates, and liner components for Northridge jobs, turnaround is faster because we’re not waiting on a shipment from out of state. For discontinued or older systems, we source aftermarket parts that meet or exceed the original specs. The goal is always the same: fix what’s broken, replace only what’s failed.

AfterDuraFlex Service Pricing in Northridge
Chimney cleaning with a DuraFlex system in Northridge typically runs between $180 and $340, depending on flue condition, liner age, and whether we’re dealing with debris or creosote stages that require more than a basic sweep. If we’re adding a Level 2 inspection, which we recommend for any home in 91324 or 91325 that hasn’t had one since the 1994 quake, expect the total to land between $250 and $450.
Crown repair or cap replacement on a DuraFlex-equipped chimney adds cost, but those are repairs, not upsells. We’ll show you the damage on camera before we quote anything. Call (866) 520-4943 for an exact quote. Estimates are free, and you’ll get a straight answer on what needs doing now versus what can wait until spring.

FAQs – DuraFlex Chimney Cleaning in Northridge
Yes, and we see the evidence on nearly every older chimney we open in 91324 and 91325. The quake shifted flue tiles and cracked crowns in ways that were never repaired because homeowners didn’t know to look. Those offsets create gaps behind DuraFlex liners where creosote accumulates and moisture gets in. If you haven’t had a Level 2 inspection since the quake, schedule one before you use the fireplace again. Call (866) 520-4943 and we’ll check it properly.
In Northridge and Valley Glen DuraFlex service areas, the most common cause we find is a liner that shifted out of alignment due to an older flue tile offset behind it. The liner itself may be fine, but the gap lets smoke and creosote collect where they shouldn’t. It could also be an uninsulated liner in an irregular original flue, which causes condensation and poor draft. Either way, a sweep alone won’t fix it. We’ll inspect the alignment and tell you exactly what’s going on.
Look for rust streaks on the flue or cap, water staining on the ceiling near the chimney, or debris inside the firebox. Santa Ana winds in late fall are particularly hard on older DuraFlex caps in Northridge, especially on single-story ranchers with no tree cover. Rain then finds the gaps and accelerates rust. If you see any of these signs, call (866) 520-4943 for a cap inspection before the next storm.
We repair crowns whenever the structure is sound. A cracked crown on a DuraFlex-equipped chimney in Northridge is often earthquake damage, and repointing plus sealing will fix it in most cases. We only replace a crown when the mortar has failed to the point that repair won’t hold. You’ll see the damage on camera before we recommend anything.
A Level 1 inspection is visual, checking the accessible parts of the chimney and liner from the top and bottom. A Level 2 inspection goes further, using camera equipment to inspect the full flue interior, which is critical in Northridge because quake damage hides behind the liner. We recommend Level 2 for any home in 91324 or 91325 that hasn’t had one since the 1994 earthquake. Call (866) 520-4943 to book either inspection.

Book Your DuraFlex Service in Northridge Today
Last fall we were called to a 1962 ranch home off Reseda Boulevard where the homeowner had a DuraFlex flexible liner installed years ago but kept getting smoke-back on still evenings. Our tech found the liner had shifted slightly due to a separated flue tile joint, likely from old earthquake settling, and the top plate seal had failed, letting in wind-blown debris. We realigned the liner, replaced the cap with a DuraFlex multi-flue model, and repointed the crown. Solved both the draft and the moisture issue. That’s the kind of repair Northridge chimneys need, and we do it every week.
