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 Liner & Rebuild in Tacoma: What to Know First
We provide independent DuraFlex chimney liner & rebuild service in Tacoma, with most liner replacements and partial rebuilds completed in one to two days after inspection. Every job starts with a written price before any work begins - no exceptions, no surprises. If your DuraFlex liner is showing gaps, corrosion at the collar, or draft readings that don’t match the appliance spec, we’ll put the camera footage and the exact cost in front of you before discussing next steps. This page is for Tacoma homeowners who know they’ve got DuraFlex in their flue and need someone who can name the part, source it honestly, and stand behind the install. Call (253) 447-5982 when you’re ready to schedule.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless flexible) - crevice corrosion at the male collar. In Tacoma’s marine climate, the salt-laden air accelerates pitting where the liner sections join, especially on west-facing chimneys in neighborhoods like Proctor District. We section-scan the full length, mark the failure point with the camera timestamp, and replace with either OEM DuraFlex SW or Olympia Chimney’s equivalent flexible liner if the homeowner prefers. The new collar gets a high-temp sealant rated for the appliance class.
- DuraFlex SS (smooth-wall) - thermal fatigue cracking above the smoke chamber. The SS series carries a smoother interior that drafts better but can develop circumferential cracks where the flue transitions through a narrow masonry throat. We find this on 1970s ranches in North Tacoma more often than you’d expect. Our fix is a partial rebuild of the smoke chamber parging plus a new SS drop, with the joint located below the stress zone per the manufacturer’s installation bulletin.
- DuraFlex AL (aluminum) - premature oxidation in gas-venting applications. Tacoma’s older homes in the Hilltop area sometimes have AL liners retrofitted for mid-efficiency furnaces that run cooler than the liner’s design threshold. Condensation pools, the aluminum oxidizes from the inside out, and the venting efficiency drops before the homeowner smells anything wrong. We swap to a properly sized DuraFlex SW or Gelco stainless flexible, sized to the appliance BTU output, not the old liner’s diameter.
- DuraFlex Pro - separation at the locking band in tall runs. The Pro series uses a heavier gauge but the locking bands can back off in chimneys over 25 feet, especially where Tacoma’s clay soil has settled and shifted the masonry shell. We find the separation with a down-flue camera pull, reseat with a fresh band and mechanical lock, and if the chimney structure is compromised, we quote the rebuild separately - no bundling, no pressure.
- DuraFlex rigid-to-flexible transitions - gasket degradation in pellet venting. The factory gasket at the appliance adapter hardens after three to four heating seasons in the Pacific Northwest humidity. Draft readings go flat, combustion efficiency drops, and the homeowner gets a lazy flame. We stock the OEM gasket and the aftermarket equivalent from Famco; we show both, price both, and let the homeowner choose. The camera doesn’t guess. Neither do we.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Schedule and scope. You call (253) 447-5982, a live person answers, and we book a Level 2 inspection. We ask the appliance type, fuel, and whether you know the existing liner brand - if it’s DuraFlex, we note the series if you have it.
- 2
Camera-scan diagnosis. Our tech runs the camera the full flue length, records the footage, and takes stills of every defect. You watch on the tablet if you’re home. We classify creosote, map liner condition, and check collar integrity.
- 3
Written price, written scope. Before any work starts, you get a single-page quote: parts (OEM DuraFlex or quality aftermarket from our Haven buying network), labor, timeline, and warranty terms. Clause 1 of the Haven Standard requires it in writing.
- 4
Parts procurement through Haven network. We source DuraFlex, HeatShield, Gelco, or Olympia Chimney materials depending on what the job actually needs - never a one-brand default. You see the part numbers on the invoice.
- 5
Install, test, document. The crew completes the liner replacement or rebuild, runs a draft test and smoke-pellet verification, and uploads the photo record to your job file. Clause 4 of the Haven Standard requires the documented record.
- 6
Walkthrough and warranty. The lead tech reviews the camera after-shots with you, explains what changed and why, and stamps the 365-Day Done Right Promise on your paperwork.

AfterWhat DuraFlex Chimney Liner & Rebuild Costs in Tacoma
These are the ranges we quote in writing for DuraFlex work in the Tacoma market. Your exact price comes after the camera inspection - never before.
| Service | Typical Range | What Moves the Price |
|---|---|---|
| DuraFlex flexible liner replacement (single appliance, standard height) | $2,800 - $4,200 | Chimney height, number of bends, access to the top (steep roof or limited clearance) |
| DuraFlex smooth-wall (SS) liner with smoke chamber parging | $3,600 - $5,400 | Extent of masonry damage, need for partial rebuild versus liner-only |
| Partial chimney rebuild with new DuraFlex liner | $5,500 - $8,500 | Courses of brick to replace, crown condition, whether the cricket needs reworking |
| Full chimney rebuild with DuraFlex liner system | $9,000 - $14,000 | Height, scaffolding requirements, matching existing masonry, liner diameter and series |
| DuraFlex collar repair or locking band reseat (no liner replacement) | $450 - $850 | Accessibility, need for additional band or sealant, secondary damage found on camera |
Tacoma’s wet winters and marine air mean we see more corrosion-related failures than inland markets. That reality is priced into our material specs, not added as a surprise later. Call (253) 447-5982 for your free estimate - the inspection itself is quoted upfront, and if you have a competitor’s written estimate, we’ll give you a free second opinion.
Why Tacoma Homeowners Call Level Two Chimney Tacoma for DuraFlex Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our liner work in Tacoma involves DuraFlex products installed in the 2010s that are now due for replacement or repair. Corrine Halstead and our crew know the difference between a SW collar that can be reseated and an SS crack that demands full replacement - and we show you the camera footage to prove which one you’ve got.
Our background-checked, uniformed technicians carry license information on every page and every truck. You get a text when your tech is en route. Calls are answered live, 24 hours a day. The 365-Day Done Right Promise covers every DuraFlex job we touch. And because we source through the Haven buying network across DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, we’re not locked into pushing one brand when another fits your system better.
FAQs
No, if the replacement is installed to the appliance manufacturer’s venting specifications and local code. As an independent DuraFlex service provider, we follow NFPA 211 and the appliance manual, not a brand script. We document the install with photos and a written compliance statement you can submit if your HVAC or fireplace warranty ever asks. Call (253) 447-5982 if you want us to review your appliance manual before we quote.
Most are completed in one working day once parts are on hand. If your chimney requires a partial rebuild or we’re matching a custom DuraFlex Pro order, expect two days. We don’t quote timelines until after the camera inspection - guessing at duration before knowing the flue condition violates Clause 1 of the Haven Standard. Call (253) 447-5982 to book your inspection.
Sometimes. A separated locking band, a degraded gasket, or localized collar corrosion can be repaired if the liner wall itself is sound - we verify this with a full camera pull and wall-thickness assessment. If the liner shows multiple cracks, thinning, or any perforation, we quote replacement because a patch on a failing flue liner is a fire hazard we won’t sign off on. The camera footage decides; we don’t. Call (253) 447-5982 and we’ll show you what we found.
We stock common DuraFlex collars, bands, and adapters at our Tacoma shop. Specialty diameters and the Pro series heavy-gauge rolls ship from our Haven network supplier within two to four business days. We never start a job until the correct part is in hand - partial installs create more problems than they solve. Your written quote includes the parts timeline before you approve anything.
The camera inspection tells us. Liner-only jobs happen when the masonry shell is sound - no spalling brick, no shifted courses, no compromised crown. A rebuild becomes necessary when the structure that holds the liner is failing; installing a new DuraFlex liner in crumbling masonry wastes your money and violates our own standard. We separate the two scopes in writing so you see exactly what each costs and why each matters. Call (253) 447-5982 for the inspection - estimates are free.
