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.
DuraFlex Chimney Repair in Tacoma: What to Know First
We provide independent DuraFlex chimney repair in Tacoma, with most jobs inspected, quoted, and completed within a week of your call. Our written price arrives before any work starts, and every repair includes a camera-scan photo record under Haven Standard Clause 4. If you own a DuraFlex liner, cap, or chase cover and you’re seeing water intrusion, draft issues, or visible deterioration, this page covers what we find and what it costs. Call (253) 447-5982 for a free estimate, or read on for the specifics.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall-flex) liner: crevice corrosion at the collar weld. In Tacoma’s marine climate, salt-laden air accelerates pitting where the flex sections meet the termination collar, especially on west-facing chimneys in neighborhoods like Ruston and North Slope. We cut back to sound metal, install a DuraFlex OEM replacement collar or a compatible 316Ti collar from our Haven network, and pressure-test the joint before we leave.
- DuraFlex AL (aluminum) liner: thermal fatigue cracking above the smoke chamber. This series wasn’t built for sustained wood-stove temperatures, yet we see it retrofitted into older Tacoma fireplaces in the Proctor District and Hilltop. The aluminum work-hardens and cracks at the first bend above the damper. We document the crack with camera footage, quote a 316 stainless DuraFlex SW upgrade if the flue run permits, or a HeatShield cerfractory resurfacing of the smoke chamber if the liner itself is still sound.
- DuraFlex chase covers: corner-seam separation after 8-12 years. The stamped galvanized covers sold in the 2015-2019 period trap condensation at the cross-break corners. We’ve replaced seventeen in Tacoma’s North End alone since 2022. We measure in place, fabricate a replacement from heavier-gauge steel or copper through our Olympia Chimney supply line, and seal with a silicone bead rated for 400°F - not the hardware-store caulk that caused the original failure.
- DuraFlex DW (double-wall) venting: joint loosening from freeze-thaw cycling. The snap-lock joints on exterior runs lose tension after repeated Tacoma winter cycles, particularly where the vent passes through an unconditioned soffit. We disassemble, inspect for inner-wall damage, reseat with fresh locking tabs or transition to a Gelco rigid section if the run geometry allows better support.
- DuraFlex termination caps: spark-arrestor mesh burnout. The factory 5/8-inch mesh on DuraFlex caps clogs with creosote in heavy-use Tacoma installations, then the cleaning fire or overheated flue burns through the screen. We source OEM replacement caps or, if the flue sizing is non-standard, fabricate a custom cap with 304 stainless mesh and a cleanout door - easier to maintain, same draft performance.
Our DuraFlex Chimney Repair Process

- 1
Schedule and arrive. You call (253) 447-5982, a live person answers, and we book a window. Corrine Halstead or a named, background-checked tech texts when we’re en route.
- 2
NFPA 211 Level 2 inspection with camera. We run the camera down the flue, record the full length, and note DuraFlex model markings where visible. The camera doesn’t guess. Neither do we.
- 3
Written price, written scope. Before any tool touches your chimney, you get a single-page quote with line-item parts: DuraFlex OEM, quality aftermarket from our Haven buying network, or a hybrid if that’s the honest fix. No surprises.
- 4
Repair with documented steps. We photo each stage: the removed part, the condition we found, the installed replacement. If we’re switching from DuraFlex AL to SW, we note the warranty implications and the code compliance in writing.
- 5
Pressure test or draft test, photo record, cleanup. Every repair gets a functional check. You receive the photo folder and the completed Haven Standard Clause 4 documentation before we pack up.
- 6
365-Day Done Right Promise. If the repair fails or the draft doesn’t perform, we return and make it right. The promise is stamped on every invoice.

Why Tacoma Homeowners Call Level Two Chimney Tacoma for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and we’ve learned that DuraFlex products fail in predictable ways - but only if you’ve seen enough of them in Tacoma’s specific climate. Our techs carry DuraFlex, HeatShield, and Gelco parts on the truck, so we’re not ordering blind and billing you for return trips. The Haven Standard requires a written price before work starts (Clause 1), a verified crew (Clause 2), on-schedule arrival (Clause 3), and that photo record on every visit (Clause 4). Corrine Halstead grew up in New York City, trained at Apex Technical School in Queens, and has spent several years working Tacoma chimneys - including the surprises that older craftsman homes in the Proctor District tend to hide. When you need DuraFlex repair done with the documentation to back it up, that’s who answers the phone.
FAQs
No, if the repair uses DuraFlex OEM parts and follows their installation manual. As an independent DuraFlex service provider, we source OEM components through our Haven buying network and document the part numbers and installation method in your photo record. If you use non-OEM parts or modify the flue geometry, warranty coverage may be affected. Call (253) 447-5982 and we’ll review what’s on your system.
Most cap, collar, or chase cover replacements are completed in two to four hours. Liner upgrades or smoke chamber resurfacing typically require a full day. We quote the time estimate in writing alongside the price, and we don’t start until you approve both. Call (253) 447-5982 to schedule.
Yes. DuraFlex has consolidated some product lines since 2018, but we maintain cross-reference documentation and source compatible fittings through Olympia Chimney and Copperfield. If no exact replacement exists, we quote a transition to current DuraFlex or an equivalent Gelco component, with the pros and cons written out. Call (253) 447-5982 for a free assessment.
The camera tells us. We look for wall thinning exceeding 25 percent, multiple cracks in a single flex section, or corrosion within 12 inches of the termination - any of these usually means replacement. Surface pitting or a single collar weld failure typically means repair. You’ll see the footage yourself before we recommend either. Call (253) 447-5982 for an inspection.
A failed liner or chase cover admits water, which damages the surrounding masonry and can reach the framing. A cracked AL liner can leak combustion gases, including carbon monoxide, into wall cavities. The risk increases with use, not time alone. We don’t pressure you with scare tactics; we show you the camera footage and let you decide. Call (253) 447-5982 for a free estimate - estimates are free.
Ready to see what’s actually going on in your flue? Call (253) 447-5982 for a free estimate. We’ll put the camera down, show you what we find, and give you a written price before any work starts. That’s Haven Standard Clause 1, and it’s how we’ve worked since 2009.
