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 Cap & Crown in West Chester: What to Know First
We provide independent DuraFlex chimney cap and crown service in West Chester, with most jobs scheduled within a week and completed in a single visit. A written price lands before any work starts, and every job includes a camera-scan inspection with a documented photo record. Typical DuraFlex cap and crown work runs $340-$890 depending on flue count, crown condition, and whether we’re matching an existing DuraFlex part or upgrading to a compatible aftermarket solution.
This page is for West Chester homeowners who already have a DuraFlex liner or cap and need repair, replacement, or an honest assessment of whether the crown beneath it is worth saving. We are not affiliated with or authorized by DuraFlex. We are an independent DuraFlex service provider with no manufacturer restrictions on what we can recommend.
Questions? Call us at (610) 321-4570. Estimates are free, and we answer live 24/7.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (Stainless Wall) multi-flue caps: The 304-grade mesh on early SW-series caps can sag after 8-12 winters in West Chester’s freeze-thaw cycle, especially on south-facing exposures where daytime heating and overnight icing stress the welds. We see this most often in the Gay Street corridor and near Marshall Square Park where the older housing stock runs tall chimneys with minimal cricket protection. We replace with either an OEM DuraFlex SW cap or a Gelco equivalent with 316-grade mesh if the flue configuration allows - the upgrade costs roughly $60 more and doubles the expected mesh life.
- DuraFlex Pro liner top collars: The Pro series uses a stamped collar that seals the liner to the cap. After repeated thermal cycling, the collar can work-harden and crack at the bend radius - a failure that’s invisible from the ground and often misdiagnosed as a cap leak. We pull the cap, camera the collar joint, and replace with either a DuraFlex Pro collar or a HeatShield-compatible transition if the liner top needs resealing. The camera doesn’t negotiate - it just shows you what’s there.
- DuraFlex AL (Aluminum) caps on oil flues: The AL line was marketed for lower-temperature applications, but West Chester’s older converted-oil systems can spike higher than the AL rating during a delayed ignition event. We find AL caps with heat-damaged mesh and distorted base pans in homes near Everhart Park and the West Chester University rental stock. We upgrade to stainless or document that the cap is within spec if the burner service records check out.
- Crown wash failure beneath DuraFlex caps: DuraFlex caps seal well when new, but a tight seal on a deteriorating crown accelerates freeze-thaw damage underneath. Water gets in at the crown edge, can’t evaporate under the cap, and the concrete spalls from below. We see this pattern in West Chester’s pre-1940 brick colonials where the original crown was a thin wash over common brick. Our fix: remove the cap, assess the crown with a hammer test and camera, then either coat with HeatShield CrownCoat or pour a new cast-in-place crown before reinstalling the cap.
- DuraFlex telescoping caps on tall flues: The telescoping feature on some DuraFlex cap models is useful for uneven flue heights, but the slip joint collects condensation in West Chester’s humid summers and can seize solid by fall. We’ve snapped two trying to adjust them in October. We now treat seized telescoping caps as replace-only, and we stock fixed-height alternatives from our Haven buying network to avoid the delay of a special order.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers. We ask for the DuraFlex model if you know it, the fuel type, and whether you’re seeing water, drafts, or animal intrusion. We book a window and text when the tech is en route.
- 2
NFPA 211 Level 2 inspection on arrival. Camera down the flue, photos of the cap and crown from the roof, and a moisture reading on the crown surface. Corrine Halstead started this practice in 2009, and it’s now Clause 4 of the Haven Standard: documented photo record on every job, no exceptions.
- 3
Written price before work. We show you the photos, name the part (OEM DuraFlex or compatible aftermarket from our Haven network), and hand you a written scope, written price, and written warranty. Haven Standard Clause 1 - have it in writing. No verbal quotes, no surprises after the ladder is up.
- 4
The repair. Cap off, crown prepped, new part installed with proper clearances and fasteners rated for the exposure. We verify mesh-to-flue spacing with a gauge, not by eye.
- 5
Post-work camera verification. We run the camera again to confirm no debris fell, no liner joint was disturbed, and the draft reading is within spec. Photos go to your record.
- 6
Cleanup and documentation. You get a written completion summary, the photo archive, and the 365-Day Done Right Promise. If it’s not done right, we make it right.

Why West Chester Homeowners Call Level Two Chimney West Chester for DuraFlex Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our West Chester work involves DuraFlex products installed during the 2015-2020 liner replacement boom. We know the Pro collar crack pattern, the AL cap temperature limits, and which Gelco or HeatShield parts cross over when DuraFlex lead times stretch out.
Our techs are background-checked, uniformed, and licensed - license number on every page, name assigned at booking, text when they’re on the way. The 365-Day Done Right Promise covers every job. And because we’re independently owned and operated, not a franchise, Corrine Halstead sets the standard and answers for it directly.
We also service HeatShield and Gelco systems, so if your DuraFlex cap sits on a HeatShield-coated crown or a Gelco multi-flue assembly, one crew handles the whole stack. No subcontractor handoffs, no blame-shifting if the interface fails.
FAQs
No - the DuraFlex liner warranty covers defects in the liner itself, not the cap, and using an independent service provider for cap or crown work does not affect that coverage. We document the liner condition before and after any cap work so there’s a clear record if a liner claim ever arises. If you have questions about your specific DuraFlex warranty terms, call us at (610) 321-4570 and we’ll review them with you.
Most single-flue replacements are done in 90 minutes to two hours; multi-flue SW caps or jobs requiring crown work take half a day. We book a morning or afternoon window, not a vague “sometime Tuesday,” and we text when the tech is 30 minutes out. Schedule your free estimate at (610) 321-4570.
We can match most DuraFlex cap models through our Haven buying network, and we’ll tell you honestly when an aftermarket equivalent from Gelco or Olympia Chimney offers better value. If your existing cap failed prematurely, we’ll explain why - mesh grade, clearance issue, crown condition - before you decide. Call (610) 321-4570 to discuss options.
Sometimes. Hairline cracks in a crown with good slope and intact flashing can be monitored; cracks that channel water toward the flue or show spalling underneath need attention. We camera the flue and photo the crown, then tell you which category you’re in and what the timeline looks like. No work is recommended without camera evidence you can see yourself. For a free assessment, call (610) 321-4570.
We stock common DuraFlex cap sizes and Pro collars for West Chester’s typical flue dimensions - 6″, 7″, and 8″ round, plus standard multi-flue widths. Uncommon sizes or custom finishes ship from our Haven network in 3-5 business days. We’ll tell you at scheduling whether your part is on the truck or on order. Call (610) 321-4570 to check availability for your model.
