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 Cap & Crown in Puyallup: What to Know First
We provide independent DuraFlex chimney cap and crown service in Puyallup, from cap replacement on a DuraFlex Pro liner system to crown coating over a DuraFlex DW flue termination. Most DuraFlex cap and crown jobs we book in Puyallup are completed within one to two business days of inspection, and every repair starts with a written price before any work begins. If you own a DuraFlex liner and the cap is rusting through, the crown is cracked, or water is getting past the termination, call (253) 323-5667. We’ll run the camera, show you what we found, and write down what it costs to fix.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex Pro series: cap skirt separation at the flue collar. The Pro’s stainless cap uses a spot-welded skirt joint that holds up well in dry climates but fatigues faster in Puyallup’s wet winters, especially on south-facing exposures where thermal cycling is sharpest. We see the skirt pull away from the collar after 6-10 years, not the 15+ the material suggests. We replace with a DuraFlex-compatible Pro cap or, when the homeowner prefers, a Gelco multi-flue cap with a heavier-gauge skirt and a longer weld seam.
- DuraFlex DW (double-wall): inner wall corrosion at the rain cap. The DW’s inner wall is 316Ti stainless, but the rain cap’s underside collects acidic condensation if the cap mesh clogs with cottonwood seed - common along the Puyallup River valley in May and June. The inner wall pits from the inside out, and the cap eventually drops into the flue. We pull the cap, camera-scan the inner wall for breach, and fit a replacement DW cap with a wider mesh spacing or a bird-screen upgrade that sheds seed better.
- DuraFlex SW (single-wall): crown wash failure over the termination. SW terminations sit lower in the chimney crown than DW or Pro systems, so the crown wash (the sloped concrete that sheds water) takes more direct splash. In Puyallup’s clay-heavy soils, chimney settlement is common in 1970s-1990s construction, and that movement cracks the crown wash. Water hits the SW collar directly, rusts the clamp band, and the liner drops. We re-pour or coat the crown with HeatShield CrownCoat, reset the SW termination to proper height, and band it with a stainless clamp rated for the collar OD.
- DuraFlex Pro: storm collar gasket hardening. The Pro’s storm collar uses a neoprene gasket that stiffens after 8-12 years of UV and freeze-thaw. Once it hardens, wind-driven rain on Puyallup’s South Hill corridor runs straight down the flue. We don’t just swap the gasket; we pull the collar, inspect the flue wall for creosote wash (which tells us how long the leak has run), and replace with a collar that uses silicone-impregnated EPDM, which we source through our Haven buying network.
- DuraFlex termination plate: fastener corrosion on multi-flue caps. When a DuraFlex liner terminates in a multi-flue chimney with a shared cap, the termination plate is held by lag screws into the crown. Those screws are often mild steel, not stainless, and they rust flat in Puyallup’s wet climate. The plate loosens, the cap shifts, and one flue ends up partially covered. We extract the old fasteners with a reverse drill, tap new holes, and set 316 stainless lags with butyl tape under the plate. If the crown is too spalled to hold a screw, we pour a new fastening pad with CrownCoat and embed threaded inserts.
Our DuraFlex Chimney Cap & Crown Process

- 1
Camera goes in first. Price gets written down second. Work starts third. Corrine Halstead runs every DuraFlex job to this sequence. We drop the camera through the flue to the termination, record the cap or crown condition, and identify the DuraFlex series from the collar stamp or termination profile.
- 2
Parts decision: OEM or quality aftermarket. We stock DuraFlex Pro, DW, and SW caps through our Haven buying network, but we’ll also spec Gelco or Famco when the chimney geometry demands it. We explain the trade-off in writing: OEM preserves any remaining warranty on the liner, aftermarket often gives better mesh or gauge for the same money.
- 3
Written scope and price delivered before work. Clause 1 of the Haven Standard requires it. You get the part numbers, labor line items, and warranty terms in writing. No verbal estimates, no “we’ll see what we find.”
- 4
The repair: cap swap, crown coat, or full crown rebuild. We match the DuraFlex collar OD exactly, band to spec torque, and seal the storm collar with high-temp silicone. For crown work, we prep with a wire wheel, apply HeatShield CrownCoat to manufacturer thickness, or form and pour a new crown if the structural concrete is compromised.
- 5
Post-repair camera verification and photo record. Clause 4 of the Haven Standard requires a documented photo record on every job. We re-run the camera to confirm the cap seats square, the mesh is clear, and no debris dropped during the repair. You get the photos and a written completion record.
- 6
365-Day Done Right Promise. If the cap leaks, the crown cracks, or the band loosens within a year, we make it right. No charge for our labor, no argument about whose fault it was.

Why Puyallup Homeowners Call Level Two Chimney Puyallup for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Puyallup’s inventory runs DuraFlex liners installed in the 2010s wood-stove boom. Corrine Halstead and our techs know the difference between a Pro collar and a DW collar by sight, and we stock the parts rather than ordering blind and making you wait. Our Haven Standard buying network keeps DuraFlex, HeatShield, Gelco, and Famco prices honest - no single-source markup. Background-checked, uniformed technicians carry license information on every page of their paperwork. Calls are answered live, 24 hours a day. And if you have a competitor’s written estimate, we’ll give you a free second opinion with our own camera evidence.
FAQs
No, if the replacement cap is DuraFlex OEM or a manufacturer-approved equivalent installed to spec. As an independent DuraFlex service provider, we source OEM caps through our Haven network and document the part number on your written record. Using a non-listed aftermarket cap or modifying the collar can void coverage. We explain the trade-off before you choose.
Most single-flue DuraFlex cap replacements in Puyallup take 90 minutes to two hours from ladder set to final photo. Multi-flue caps or jobs requiring crown repair add time. We book by the job, not the hour, so the price is the price even if we hit a seized fastener.
Yes. Crown repair and liner replacement are separate systems. We camera-scan the liner to confirm it’s sound, then address the crown with HeatShield CrownCoat or a full rebuild. If the liner also needs work, we quote it separately and you decide. Nothing is bundled or assumed.
A failing cap shows rust streaks on the flue tile, mesh corrosion visible from the ground, or water in the firebox after rain. A dirty cap just has soot buildup. We camera-scan from the top down to tell the difference and show you the footage. Call (253) 323-5667 and we’ll check - estimates are free.
We stock DuraFlex Pro, DW, and SW caps, collars, and storm collars in our Puyallup warehouse. Unusual sizes or custom mesh ship in two to three business days through our Haven buying network. We never start a job with parts on order unless you’ve agreed to the timeline in writing.
