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.

AfterWhy Tacoma Homeowners Choose DuraFlex Chimney Cleaning
Level Two Chimney Tacoma provides independent Tacoma Duraflex service - chimney cleaning, inspection, and repair - across Tacoma’s older neighborhoods, with camera-scan diagnosis and a written price before any work begins. We are not affiliated with, endorsed by, or authorized by DuraFlex - we diagnose each stainless liner on its actual condition and recommend only what the inspection evidence supports. Call (253) 447-5982 for a free estimate.
DuraFlex stainless steel flexible liners are common in Tacoma’s pre-WWII housing stock, especially in the North End, Stadium District, and Hilltop where original unlined brick chimneys built for coal were retrofitted for wood or gas. We’ve cleaned and inspected thousands of these relining systems since 2009, and we’ve learned how DuraFlex’s 316L and 304 alloys, insulation wraps, and termination components hold up against Puget Sound’s persistent moisture. The camera doesn’t guess. Neither do we. Every DuraFlex service includes NFPA 211 Level 2 camera inspection, a documented photo record under Haven Standard Clause 4, and your written scope and price before anyone touches a tool - the same thoroughness you’d expect from any professional Chimney Cleaning & Sweep.
Why Trust Level Two Chimney Tacoma for Your DuraFlex Chimney Cleaning?
Corrine Halstead and our crew have been working chimneys across Tacoma for several years, including jobs in the Proctor District where older craftsman homes tend to surprise you with flue conditions nobody’s looked at in decades. Corrine picked up the fundamentals of this trade at Apex Technical School in Queens before relocating to the Pacific Northwest, and she built Level Two Chimney Co. on the principle that evidence comes before sales pressure.
We know DuraFlex products specifically. We understand how the 316L alloy resists acid condensate better than 304, but neither grade survives indefinite pooling of corrosive flue moisture in a poorly vented gas setup. We’ve seen insulation wrap degrade and hold water like a sponge in Tacoma’s marine climate, accelerating exterior pitting that the homeowner can’t see from the hearth. Our techs carry DuraFlex-compatible liner sections, tees, caps, and replacement insulation in the van - not because we default to replacement, but because we can complete honest repairs same-visit when the inspection shows they’re warranted.
We’re independently owned and operated under the Haven Standard. Every technician is background-checked and uniformed, with license information displayed on every page. You get a named tech assigned, a text when they’re on the way, and a written warranty stamped with our 365-Day Done Right Promise before they leave.
Common DuraFlex Chimney Cleaning Problems We Fix in Tacoma
- Condensate corrosion in lower liner sections on gas and high-efficiency appliance venting. DuraFlex 304 alloy liners connected to gas inserts or furnaces in Tacoma’s damp climate produce acidic flue moisture that pools in the bottom section and pits the stainless wall from the inside out. We catch this with camera inspection - the pitting shows as orange-brown freckling on the 316L or 304 wall - and we tell you honestly whether the wall thickness still meets safe spec or replacement is necessary.
- Glazed creosote and hard carbon buildup on wood-burning DuraFlex liners. This happens when a DuraFlex 316L liner was sized or insulated for a different appliance than the one now connected, or when the homeowner burns unseasoned wood. The creosote bakes into a glassy, tar-like layer that standard wire brushes won’t touch. We use poly brushes and controlled mechanical action to remove it without scoring the stainless surface, then document the clean wall with camera footage.
- Insulation wrap degradation and moisture saturation. In unlined or poorly flashed Tacoma chimneys, DuraFlex’s pre-insulated wrap absorbs groundwater and humid air that wicks down from the crown. The wrap compacts, loses its thermal rating, and holds moisture against the liner exterior. We’ve pulled saturated wraps in Stadium District homes where the liner looked fine from inside but was pocked with exterior corrosion hidden by the wet blanket. We replace the wrap and address the water source - usually crown cracks or missing flashing - so it doesn’t repeat.
- Mechanical damage at the top termination and tee. Crushed or kinked flex at the cap connection comes from improper original install, debris impact, or a cap that was forced onto an oversized collar. A kinked DuraFlex liner restricts draft, traps condensate, and creates a creosote collection point. We cut back to sound metal, re-terminate with proper support, and fit a cap that matches the liner diameter and flue load.
- Smoky backdraft and odor on damp days. We were called to a 1920s Tacoma bungalow where a DuraFlex 316L liner had been installed years earlier in a wood-burning fireplace, and the owner reported exactly this. Our tech pulled the cap and found heavy glazed creosote in the upper third plus a kinked section where the flex met the tee. We swept the liner with poly brushes, removed the creosote, corrected the tee connection, and fitted a new multi-flue cap to stop rain intrusion. Draft tested clean. Written price before we started; photo record after.

AfterDuraFlex Parts & Our Repair-vs-Replace Approach
We stock DuraFlex-compatible OEM-spec components - liner sections, tees, caps, and insulation wraps - for repair work that preserves an otherwise sound system. Where quality aftermarket stainless hardware meets the same alloy and gauge standards at lower cost, we’ll quote both options with the spec sheet so you can choose.
Our rule is simple: if corrosion has compromised the wall thickness or pitting exceeds safe depth, we say replacement. If the liner wall is sound but the termination, wrap, or connection needs attention, we repair. You’ll see the camera footage that supports either call before we discuss next steps. No defaulting to the bigger ticket.
Materials come through Haven’s buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - sourced specifically to keep customer prices honest. Call (253) 447-5982 and we’ll bring the right parts to your Tacoma home.
Our DuraFlex Service Process - Step by Step
- 1
Diagnosis with NFPA 211 Level 2 camera inspection. We run a high-resolution camera the full length of your DuraFlex liner, documenting wall condition, creosote class, joint integrity, and any corrosion, kinking, or wrap saturation. You see the footage in real time. We note the alloy grade if it’s visible on the collar stamp.
- 2
Written scope and price before work starts. Haven Standard Clause 1: have it in writing. We deliver a written price, written scope, and written warranty before anyone picks up a tool. No exceptions.
- 3
Repair or install with DuraFlex-compatible components. Sweeping, creosote removal, re-termination, wrap replacement, or full relining - done with the alloy and gauge matched to your system and appliance type.
- 4
Draft and flow testing. We verify proper draw and document the readings. A DuraFlex liner that doesn’t vent correctly is a carbon monoxide risk, regardless of how clean the wall looks.
- 5
Documented photo record and warranty. Haven Standard Clause 4 requires a photo record on every job. You get the archive, plus our 365-Day Done Right Promise in writing. If it’s not done right, we make it right.

FAQs - DuraFlex Chimney Cleaning Service in Tacoma
No. We are an independent chimney contractor, not affiliated with, endorsed by, or authorized by DuraFlex. We service DuraFlex products based on hands-on field experience and NFPA 211 standards, not manufacturer certification. Our independence means we diagnose your liner on condition, not on a script to sell replacement.
We use DuraFlex-compatible OEM-spec components when they offer the best match for alloy, gauge, and fit. We also use quality aftermarket stainless hardware that meets the same material standards where it saves you money without compromise. We show you the spec and let you decide.
A standard DuraFlex sweep and Level 2 inspection takes 60-90 minutes in most Milton Duraflex service areas and Tacoma homes. If we find glazed creosote requiring mechanical removal, or if re-termination or wrap replacement is needed, plan on 2-3 hours. We book by the job, not the clock - the written price doesn’t change if it runs long.
We service DuraFlex 316L and 304 flexible liner kits, DuraFlex Insulated Flex Liner systems, and DuraFlex Pro systems with tee and cap components. If you have a DuraFlex product not on this list, call (253) 447-5982 - we’ve likely seen it, and if not, we’ll tell you straight.
Manufacturer warranties typically require installation by a qualified professional and may specify OEM parts for covered repairs. As an independent provider, we cannot guarantee warranty preservation - we document our work with photos and written scope so you have evidence of proper service if a warranty claim arises. Ask us to review your warranty terms before we begin if this is a concern.
DuraFlex chimney cleaning and Level 2 inspection in Tacoma typically runs $275-$425 for a standard sweep, depending on creosote class and accessibility. Glazed creosote removal adds $150-$300. Re-termination, cap replacement, or insulation wrap work is quoted item by item after inspection. We deliver a written price before any work starts - no exceptions. Call (253) 447-5982 for an exact quote; estimates are free.
Yes, in most cases. We use poly brushes and controlled mechanical action designed for stainless liners to remove glazed creosote without scoring the 316L wall. Severe buildup that has narrowed the flue beyond safe dimension may require section replacement - we’ll show you the camera measurement before recommending it.
The smell usually means moisture is entering the chimney and reactivating creosote residue on the liner wall or in the smoke chamber. In Tacoma’s wet climate, missing or damaged caps, cracked crowns, or failed flashing let rain and humid air down the flue. We find the entry point with camera inspection and fix it - cap, crown, or flashing - then sweep the residue so the odor doesn’t return.
A properly sized and terminated DuraFlex 316L liner is suitable for gas inserts, but Tacoma’s damp climate makes condensate management critical. Gas flue moisture is acidic and pools in low spots if the liner isn’t pitched correctly or if draft is inadequate. We inspect for condensate drainage, verify proper liner sizing to the appliance BTU rating, and check that the termination prevents rain entry while allowing moisture escape.
Replacement is necessary when camera inspection shows wall pitting that exceeds safe depth, through-wall corrosion, or mechanical damage that can’t be re-terminated without compromising draft. We measure pitting against the original gauge, show you the footage, and explain the safety margin. If the wall is sound, we sweep and document - no pressure to replace what still works.
Yes - the cap must match the liner diameter, allow proper draft for the appliance type, and exclude rain without trapping condensate. In Tacoma’s wet climate, we see too many generic caps forced onto DuraFlex collars, causing kinks, rust, and draft problems. We fit caps spec’d to your liner and flue load, with proper support to prevent flex damage at the termination.
