This page is for Elmhurst homeowners who know they’ve got a DuraFlex component on their chimney and need to know whether the cap is keeping water out, whether the crown is cracked, and what fixing it will actually cost. We don’t sell you a part you don’t need, and we don’t start work without a written scope and price.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW 304/316 multi-flue caps: The mesh on these caps is 18-8 stainless, but the spot-welded seams at the corner gussets fatigue after 8-12 winters in Elmhurst’s freeze-thaw cycle. We see this most on homes near York Woods where mature oak canopies drop debris that accelerates corrosion at the weld points. We replace with either an OEM DuraFlex cap or a Gelco equivalent with fully seam-welded construction, depending on flue configuration.
• DuraFlex DSA storm collars on crown-mounted caps: The EPDM rubber gasket hardens faster than the metal it seals, especially on south-facing chimneys in Elmhurst that take afternoon sun. Water tracks under the collar and saturates the crown from the inside out. We pull the collar, assess crown integrity with a hammer test, and either reseat with a fresh silicone compression seal or recommend crown coating if the concrete is spalling.
• DuraFlex 7″ and 8″ round caps with internal spark arrestor: The arrestor screen on these caps traps creosote particles that bake into a hard glaze during shoulder-season burns. In Elmhurst, where homeowners often run fireplaces intermittently through April, this buildup restricts draft and can distort the cap skirt. We remove the cap, media-blast the arrestor clean or replace it if the mesh is compromised, and verify draft with a manometer before we leave.
• DuraFlex DFW wind-directional caps: The brass bushing in the pivot mechanism seizes when homeowners skip annual sweeping, which is common on second-home or rental properties near Elmhurst College. A seized cap doesn’t rotate, which means it doesn’t vent properly in crosswinds. We free the mechanism with penetrating oil and bushing replacement, or recommend a fixed-cap conversion if the pivot housing itself is ovalized from wind load.
• DuraFlex crown wash systems (proprietary cementitious coating): DuraFlex’s factory crown coating is a one-part polymer-modified cement that shrinks on cure. In Elmhurst’s climate, with 38 inches of annual precipitation and repeated freeze-thaw, we’ve seen this coating delaminate from the concrete substrate in 4-6 years, trapping moisture underneath. We strip the failed coating, expose the bare crown, and apply HeatShield CrownCoat or a poured concrete rebuild depending on crack depth and rebar exposure.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. Our phone is answered live, 24/7. We ask for your chimney’s approximate age, last sweep date, and what you’re seeing (water in the firebox, rust stains on the brick, cap noise in wind). We book a window and text when your tech is en route.
2. 2
   NFPA 211 Level 2 inspection with camera. We run a camera down the flue before touching the cap or crown. Clause 4 of the Haven Standard requires a photo record on every job, and for DuraFlex systems we want to confirm the flue liner condition before we disturb anything above the roofline. The camera doesn’t editorialize. Neither do I.
3. 3
   Diagnosis and parts decision. We name what we found: cap model, failure mode, crown condition class (sound, spalling, cracked through, or rebar-exposed). For DuraFlex parts, we check OEM availability against our Haven network inventory. If DuraFlex lead time exceeds 10 business days and the customer needs the repair sealed before burning season, we quote a quality aftermarket equivalent with equivalent gauge and warranty terms.
4. 4
   Written price, written scope, written warranty. You get all three before anyone picks up a tool. Haven Standard Clause 1: have it in writing. No exceptions.
5. 5
   Repair and test. Cap or crown work is completed, flue is camera-checked again for debris or disturbance, and draft is verified. We photograph the finished work for your record and ours.
6. 6
   Cleanup and documentation. You receive a printed summary with photos, the written warranty, and our 365-Day Done Right Promise. We keep copies on file. Corrine reviews every photo set personally.

What DuraFlex Chimney Cap & Crown Costs in Elmhurst

These are Elmhurst market ranges based on jobs we’ve completed in the last 24 months. Your exact price depends on what the camera shows and what we measure on site. We don’t estimate over the phone for crown work because “a few cracks” can mean anything from surface crazing to structural failure. Call (708) 498-3199 for a free estimate - we’ll put it in writing before any work starts.

Why Elmhurst Homeowners Call Level Two Chimney Elmhurst for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Elmhurst’s housing stock from the 2005-2015 build wave came with DuraFlex components originally. Corrine Halstead and our crew know the difference between a DuraFlex SW and a DSA cap without climbing down to check the stamp - the skirt profile and fastener spacing are distinct. When DuraFlex parts are backordered, we source equivalent-spec materials from Gelco or Olympia Chimney through our Haven buying network, and we tell you exactly what you’re getting and why.

Every tech is background-checked and uniformed, with license information on the page and a text when they’re on the way. The 365-Day Done Right Promise applies to every job. And if another company handed you a written estimate that doesn’t sit right, our Free Second Opinion is exactly that - free, written, and no obligation.
