A Level company - serving Pasadena, CA

DuraFlex Chimney Cleaning & Sweep Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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 & Sweep in Pasadena: What to Know First

We provide independent DuraFlex chimney cleaning and sweep services throughout Pasadena, typically scheduling within 3-5 business days during peak season and 1-2 weeks in summer. Every job starts with a camera-scan inspection and a written price before any work begins - no exceptions. If you own a DuraFlex liner, cap, or chimney component and need creosote removal, a Level 2 inspection, or annual sweep maintenance, we’ll document the condition, name the exact scope, and give you a flat price you can hold in your hand before we start. Call (213) 459-6058 to speak with a live person now.

How DuraFlex Products Fail - and How We Fix Them

  • DuraFlex SW (stainless wall) liners with premature seam separation. The SW series uses a corrugated 316Ti stainless body with a smooth inner wall, but we’ve found the longitudinal seam weld can open at stress points where Pasadena’s Santa Ana wind cycles create thermal shock - rapid heating followed by sudden cooling as downdrafts hit. We camera-scan the full length to map separation points, then sleeve with a compatible 316Ti insert or perform a partial reline using DuraFlex-compatible components sourced through our Haven buying network.
  • DuraFlex Pro liner crowns that pool condensation. The Pro series termination caps with lower-profile rain guards were common in 2016-2019 Pasadena installations. Their shallow pitch collects moisture against the flue collar during our wet winters, accelerating creosote glazing into Class III (glassy, tar-like) buildup that standard brushes won’t touch. We remove the cap, rotary-mechanically clean with a chainsaw head at controlled RPM, and upgrade to a Gelco or Famco high-pitch cap with a 4-inch minimum overhang.
  • DuraFlex 30° and 45° elbow sets with creosote bridging. These factory elbows, especially in the 6-inch and 8-inch diameters we see in Bungalow Heaven conversions, create low-velocity zones where creosote spans the inner curve. Homeowners smell a chemical, acrid odor before they see smoke backup. We disassemble the elbow set where accessible, mechanically clean each segment individually, and verify draft with a digital manometer before reassembly.
  • DuraFlex Light (aluminum) liners in exterior chase applications. Aluminum was specified for some 2017-2020 Pasadena townhome installations to cut cost. It doesn’t survive our summer attic temperatures above 140°F; we’ve found warped sections near the top third that trap condensation and accelerate corrosion. We document with photos, quote a 316Ti stainless replacement, and never recommend another aluminum run in a California exterior chase.
  • DuraFlex tee connectors with cleanout door seal failure. The factory EPDM gasket on tee bodies installed 2014-2018 hardens in dry heat. Smoke leaks into the basement or crawl space, often misdiagnosed as a masonry crack. We replace with a high-temp silicone gasket rated to 500°F, verify with a smoke pellet test, and note the repair in your documented photo record under Haven Standard Clause 4.

Our DuraFlex Chimney Cleaning & Sweep Process

Our DuraFlex Chimney Cleaning & Sweep Process
  1. 1
    Call intake with live person. We confirm your DuraFlex model or series if known, your address in Pasadena or nearby, and schedule a Level 2 inspection with camera. You’ll receive a text when your technician is en route.
  2. 2
    NFPA 211 Level 2 camera-scan inspection. Corrine Halstead and our technicians run a 360-degree camera the full flue length. We show you the footage before quoting anything. The camera doesn’t negotiate - it just shows what’s there.
  3. 3
    Written scope, written price, written warranty. Haven Standard Clause 1: you get all three before work starts. For DuraFlex components, we specify OEM versus quality aftermarket parts (HeatShield for refractory repair, Olympia Chimney for compatible stainless components) and explain the trade-off.
  4. 4
    Mechanical cleaning and component service. Rotary or manual cleaning based on creosote class. Elbow disassembly, cap replacement, or tee resealing as scoped. No work outside the written agreement.
  5. 5
    Post-service testing and documentation. Draft test with digital manometer, smoke test on any sealed component, then a photo record uploaded to your job file. Haven Standard Clause 4 requires this archive; we’ve done it on every job since 2009.
  6. 6
    365-Day Done Right Promise activation. Your warranty is stamped and dated. If it’s not done right, we make it right.

Why Pasadena Homeowners Call Level Two Chimney Pasadena for DuraFlex Work

Why Pasadena Homeowners Call Level Two Chimney Pasadena for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our Pasadena calls involve DuraFlex components installed during the 2015-2020 liner boom. Corrine Halstead grew up in Queens, learned the trade through Queensborough Community College’s building maintenance and HVAC programs, and put in years on actual rooftops before establishing our Pasadena operation. She and our crew know the local housing stock - the craftsman properties near Bungalow Heaven with their odd chase dimensions, the postwar ranch conversions with exterior aluminum runs that failed early - and we source materials through our Haven buying network specifically to keep customer prices honest.

Our technicians are background-checked, uniformed, and licensed; their license number appears on every page. You get a named tech, a text when they’re on the way, and a documented photo record when the job is done. We also service HeatShield and Gelco systems, so if your DuraFlex installation needs a compatible component we don’t stock, we know where to get it without marking up through three middlemen.
