Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Sylmar Residents Choose Us for DuraFlex Service
We’ve pulled bird nests, palm fronds, and wind-blown brush out of chimneys in Pacoima and across Sylmar more times than we can count, and that matters when you’re picking a chimney company. Our crew knows how DuraFlex SS flexible liners hold up under the valley’s dry heat, how they glaze with creosote after heavy winter use, and what to look for where moisture collects at the tee. Noel Braddock, our owner, grew up in the West Valley and trained in HVAC and building systems at Los Angeles Pierce College before spending well over a decade working chimneys and dryer vents across the northeast Valley. That background shows up in how we diagnose problems, not in a sales pitch.
We use genuine DuraFlex components where they’re available and quality aftermarket stainless parts that meet the same spec where that makes more sense. The goal is always a correct match to your liner’s diameter, grade, and connection style. You won’t get a universal adapter and a shrug. For DuraFlex sales & service, we’re the crew Sylmar calls when a sweep-only company finds something they can’t fix.

Common DuraFlex Chimney Cleaning Problems We Solve in Sylmar
- Off-season nesting in unscreened or damaged caps. Sylmar’s hot, dry summers mean chimneys sit idle for months, and birds and rodents move into any flue with a torn screen or missing cap. We regularly clear nests packed into the top section of DuraFlex liners before the first winter fire, then fit a new stainless cap with an intact spark-arresting screen.
- Creosote glazing on flexible liner walls. When you burn short, hot fires off-season and then run the fireplace heavily from December through January, the inner wall of a DuraFlex flexible liner builds a hard, shiny creosote layer. It’s stubborn stuff and a plain brush won’t remove it. We use rotary cleaning tools sized to the liner to get the flue back to bare stainless.
- Corrosion and pitting at the bottom section and tee. In underused flues, condensation collects at the bottom of the liner and sits there. Over time that moisture eats at the stainless, especially near the tee connection. We see this on Sylmar homes where the fireplace only gets used a few times a season. A camera inspection tells us whether it’s surface rust or structural pitting that calls for a section replacement.
- Cap distortion and screen separation after Santa Ana events. High wind episodes drive branches and debris into chimney terminations across the 91342 foothills. We’ve found DuraFlex cap screens pushed inward, bent, or separated at the seam, which opens the flue to embers and animals. If the screen is compromised, the ember-intrusion risk is real, not theoretical.
- Draft blockages from wind-blown brush and palm fronds. Sylmar sits right at the mouth of the I-5 corridor where wind funnels straight into the northeast Valley. Palm fronds and dry brush debris land on roofs and drop into chimney caps. A clogged DuraFlex flue smokes back into the house on first use, and in canyon-adjacent neighborhoods, that’s a sign the whole termination needs a screen upgrade.
DuraFlex Service in Sylmar: What Local Conditions Mean for Your Equipment
Here’s something a generic chimney page won’t tell you. Many 91342 homes back directly onto brushy foothill and canyon terrain, which makes a screened, debris-free DuraFlex cap a fire-hardening item homeowners and their insurers care about, not just a draft fix. When Santa Ana winds push embers across those canyon edges, a compromised spark arrestor on a DuraFlex termination becomes an entry point for fire into the flue. We’ve worked homes along the foothill streets off Foothill Boulevard where the brush is close enough to throw shadows on the roof, and the difference between a clean cap and a packed one is the difference between safe burning and an insurance conversation you don’t want to have. We also provide DuraFlex service in Mission Hills with the same fire-hardening focus. Our Level 2 camera inspections document cap and liner condition so Sylmar homeowners have evidence for their insurer that the chimney is maintained. That’s the work we do here that wouldn’t be the same in Winnetka or Calabasas.
DuraFlex Models & Products We Service in Sylmar
We service the full DuraFlex flexible liner range, including the round SS series in 316L and 316Ti stainless, the DuraFlex Pro and SW smooth-wall systems, rigid stainless sections and tees, and stainless caps with multi-flue assemblies. For Sylmar turnaround, we keep common 6-inch and 5.5-inch flex liner components and stainless caps stocked, which means cap replacements don’t sit on backorder while your flue stays unscreened. Our DuraFlex repair in Arleta uses the same stocked inventory for faster service there too. When we quote a repair, we match the existing system’s diameter, grade, and connection style with genuine DuraFlex parts where they’re available and equivalent-spec aftermarket stainless where they aren’t. We never install a mismatched adapter to force a sale.

FAQs – DuraFlex Chimney Cleaning in Sylmar
Smoking after a Santa Ana stretch usually means the flue or cap screen is packed with wind-blown debris – palm fronds, dry brush, or a bird nest that moved in during the off-season. Your DuraFlex liner is likely sound; the blockage is at the top or in the first few feet of the flue. We clear it the same day and inspect the cap for damage. Call (877) 939-1446 and we’ll get it sorted before the next cold snap.
Yes, it does. Homes that back onto brushy foothill terrain need a spark-arresting screen on the chimney termination to meet basic defensible-space logic, and a torn or missing screen is an ember entry point. A clean, intact stainless cap keeps wind-driven embers out of the flue. If you need documentation for your insurer, a Level 2 inspection with camera photos covers it. Call (877) 939-1446 to schedule a cap check.
Once a year, before the winter burning season, but homes that burn frequently from December through February may need a second sweep mid-season. Sylmar’s off-season humidity swings let creosote settle and harden in flexible liner walls, so the annual sweep does more than clear soot; it removes glazing before it becomes a chimney fire risk. Call (877) 939-1446 to get on the schedule before cold nights arrive.
We usually can. If the liner is stainless, structurally sound, and the damage is limited to a section or the tee, we replace that section with a matched component rather than quoting a full reline. We’ll show you the camera footage so you can see the damage yourself. If the liner is past saving, we’ll tell you that plainly. Call (877) 939-1446 to talk through what your camera inspection showed.
No. A nest packed into a DuraFlex liner is a chimney fire starter and can damage the liner when it burns hot and fast. It also blocks oxygen flow and pushes smoke back into the house. We’ll pull it out, sweep the liner clean, and check the cap screen so it doesn’t happen again. Call (877) 939-1446 and we’ll have it out same visit.
