Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Cleaning & Sweep in Olympia: What to Know First
We provide independent DuraFlex chimney cleaning and sweep service in Olympia, typically scheduling within 3-5 business days during sweep season and 1-2 weeks in peak fall demand. A standard DuraFlex sweep and Level 2 inspection runs $289-$389 for most Olympia homes, with a written price delivered before any work starts. This page is for homeowners with DuraFlex flue liners, chimney caps, or venting components who need documented cleaning, creosote removal, or condition assessment backed by photo evidence they can see themselves. Call (360) 464-2015 for a free estimate - we’ll ask for your DuraFlex model or series if you know it, and we’ll bring the right fittings either way.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall-flex) liner: creosote bridging at corrugation valleys. The SW’s helical corrugations trap condensed flue gases in Olympia’s long, wet heating season - October through May - accelerating Class II and III creosote buildup in the valley grooves where brushes miss. We run a rotary poly or flat wire brush sized to the exact corrugation pitch, then camera-verify the valleys are clean. If the liner’s pulled away from the top collar, we document it and quote re-attachment with a DuraFlex-compatible top plate or quality aftermarket equivalent.
- DuraFlex 316Ti chimney liner: premature weld-seam corrosion from Pacific Northwest condensation cycling. The 316Ti alloy resists acid well but the longitudinal weld seam is the weak point; Olympia’s freeze-thaw cycles in uninsulated exterior chases push moisture through microscopic weld gaps. During sweep and inspection we magnify-scan the seam at the exposed top and bottom thirds - where thermal shock concentrates - and flag pitting before it breaches. If replacement is needed, we source 316Ti or upgrade to AL29-4C through our Haven buying network.
- DuraFlex Pro cap and collar assemblies: mesh screen collapse from heavy creosote droppings. The Pro series uses a finer spark screen than competitor caps; when creosote sloughs off a neglected liner, the mesh loads up and restricts draft. We remove the cap assembly as part of every sweep, ultrasonic-clean or replace the screen, and check the collar seal to the flue tile. A blocked Pro cap in Olympia’s damp climate can back-puff smoke into the living space within one season.
- DuraFlex DW (double-wall) vent connectors: joint separation at expansion loops. The DW’s built-in expansion compensation loops fatigue at the crimp joints after 8-12 years of daily cycling - common in Olympia’s 1960s-1980s ranch homes where the connector runs long to reach a basement hearth. We inspect each loop joint with borescope and light tension test; if separation exceeds 1/8 inch, we quote replacement with OEM DuraFlex DW or a compatible Gelco double-wall section, your choice, priced both ways in writing.
- DuraFlex relining top plates: gasket hardening from UV exposure on south-facing Olympia roofs. The silicone gasket between top plate and flue tile degrades faster on unshaded Capitol Campus-area and Eastside homes. We check gasket compression and flue gas bypass during every Level 2 inspection; replacement with a DuraFlex-spec or Olympia Chimney top plate takes 30 minutes and prevents the hidden water damage that destroys smoke chambers.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call intake with model identification. We ask for your DuraFlex series, installation year, and any symptoms - draft issues, smoke odor, previous sweep date. Corrine or a live person answers 24/7; no voicemail, no web-form delay.
- 2
Scheduled arrival with text notification. Your assigned, background-checked technician texts when en route, license number included. We arrive in uniform with DuraFlex-compatible tooling and common replacement parts on the truck.
- 3
Camera-first inspection before any cleaning. The camera goes in first. Everything else follows from what it finds. We document liner condition, creosote class, joint integrity, and cap function - photos and video, time-stamped, stored to your job record under Haven Standard Clause 4.
- 4
Written price and scope before work starts. Clause 1 of the Haven Standard: you get the exact cost, the exact work, and the exact warranty in writing. No surprises, no “while we were here” add-ons. You approve or decline; either way, you keep the inspection documentation.
- 5
DuraFlex-specific cleaning and any repair. Rotary or manual sweep matched to your liner corrugation and alloy; cap removal and cleaning; joint and gasket service as quoted. OEM or quality aftermarket parts - we stock both, priced honestly through our Haven materials network.
- 6
Post-work camera verification and documentation. Second camera pass confirms clean flue, intact joints, proper draft. You receive the photo record, written warranty, and 365-Day Done Right Promise before we leave.

Why Olympia Homeowners Call Level Two Chimney Olympia for DuraFlex Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Olympia’s housing stock - the 1990s-2010s builds in Tumwater, Lacey, and the older Eastside neighborhoods - runs DuraFlex. Corrine Halstead and our crew know the difference between SW corrugation pitches and when a 316Ti weld seam is cosmetic versus structural. We don’t guess; we camera-verify and write it down.
The 365-Day Done Right Promise covers every job. Our materials come through the Haven buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no single-source markup, no pushing one brand because it’s all we stock. And because we’re independently owned and operated, not a franchise, the technician who quotes your job is accountable for finishing it right.
FAQs
No - proper chimney cleaning by a qualified professional does not void DuraFlex’s liner warranty, though damage caused by improper tools or technique does. We use brushes and rods matched to your specific DuraFlex corrugation pattern and alloy, and we document our methods in your photo record. If a warranty claim ever arises, you have dated proof of professional maintenance. Call (360) 464-2015 if you need a copy of your inspection archive.
The camera shows the difference. Surface creosote, even heavy buildup, cleans off. Pitting, seam separation, or deformation in the liner wall does not. We separate these findings in your written report - “cleanable” versus “requires repair or replacement” - with photos of each. No work is recommended without camera evidence you can see. Call (360) 464-2015 for a free inspection if you’re unsure.
We stock common DuraFlex caps, collars, top plates, and DW connector sections on our Olympia trucks, and our Haven network sources less common 316Ti and AL29-4C liner sections within 3-5 business days. For urgent safety issues - a separated liner, breached weld seam, or blocked flue - we can often install a temporary safe configuration same visit while OEM parts ship. Call (360) 464-2015 to check current stock for your series.
NFPA 211 recommends annual inspection; sweep frequency depends on use and fuel. In Olympia’s wet, mild winters, we see more condensation-driven creosote than drier climates, so wood-burning DuraFlex liners often need sweeping every cord of wood burned or annually, whichever comes first. Gas and pellet DuraFlex venting typically needs inspection yearly and cleaning every 2-3 years unless debris or animal nesting intervenes. Call (360) 464-2015 and we’ll ask about your fuel, usage, and last service date to recommend a schedule.
Class III glazed creosote ignites at approximately 450°F - well within normal flue operating temperatures - and burns at 2,000°F+, which can damage even stainless DuraFlex liners and ignite adjacent framing. In Olympia’s older homes with balloon framing or uninsulated chases, chimney fire spread is rapid. Carbon monoxide intrusion from a blocked or separated liner is the quieter hazard, with symptoms mistaken for flu season. Neither risk requires alarmism; both require a clean flue and intact liner, verified by camera. Call (360) 464-2015 for a free estimate - estimates are free, and we’ll tell you honestly if your system can wait.
