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 Liner & Rebuild in Arlington Heights: What to Know First
We provide independent DuraFlex chimney liner and rebuild service in Arlington Heights, with most liner replacements completed in one day and full rebuilds typically finished inside three days. Every job starts with a written price before any work begins - no exceptions, no surprises. If you own a DuraFlex liner that’s showing gaps, corrosion, or draft failure, or you’re facing a partial or full chimney rebuild, call (331) 202-2419. We answer live, 24/7.
Corrine Halstead and our crew have been running camera inspections and DuraFlex liner jobs across Arlington Heights for years, including plenty of calls near the shops and older colonials along Campbell Street. The camera doesn’t guess. Neither do we.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless flexible) liner: crevice corrosion at the flex points. The SW’s 316Ti alloy handles most flue gases well, but in Arlington Heights we see accelerated corrosion where the liner flexes to navigate offset flues in 1960s ranch and split-level construction. The gap between liner and masonry traps acidic condensation. We pull the damaged section, verify wall thickness with a micrometer, and replace with matching DuraFlex SW or upgrade to DuraFlex Pro if the appliance has shifted to a higher-efficiency unit.
- DuraFlex Pro (heavy-wall flexible): thermal fatigue at the top collar. The Pro’s thicker wall resists abrasion, but the factory top collar is a stress concentrator. After 10-15 years of Arlington Heights freeze-thaw cycling, we see circumferential cracking just below the collar. We don’t patch this - we cut back to sound metal, install a field-fabricated transition, and document the repair with photos under Haven Standard Clause 4.
- DuraFlex AL (aluminum) liner: premature failure in gas-to-oil conversions. Arlington Heights has plenty of homes that started gas and converted back to oil or added a solid-fuel insert. DuraFlex AL is rated for gas only; when an oil appliance gets connected, the liner sulfidizes from the inside. We find this on camera as a white, flaky scale. The fix is full replacement with DuraFlex SW or Pro, never a sleeve-over, and we note the fuel mismatch in the written report for the homeowner’s records.
- DuraFlex rigid liner: joint separation in tall runs. The rigid system seals with compression gaskets that degrade above 1,200°F. In Arlington Heights, we see this where homeowners burn unseasoned hardwood (common with the local ash and maple stock) and run the appliance hot. We inspect every joint with a borescope, replace compromised gaskets with OEM or high-temp aftermarket equivalents from our Haven buying network, and pressure-test the assembly.
- DuraFlex tee and wye fittings: condensate pooling in the dead leg. The tee fitting’s side branch creates a low spot where acidic condensate collects, especially in exterior chimneys on north-facing walls - a frequent layout in Arlington Heights neighborhoods like Scarsdale and Hasbrook. We see wall thinning at the 6 o’clock position. Our fix is fitting replacement with a condensate drain if the appliance allows, or reconfiguration to eliminate the dead leg entirely.
Our DuraFlex Chimney Liner & Rebuild Process

- 1
Call and schedule. A live person answers. We book a Level 2 inspection with camera scan. You get a text when your tech is en route.
- 2
Inspection and documentation. We run the camera the full flue length, record liner condition, creosote stage, and any gaps or spalling. You see the footage in real time. Corrine’s crew writes up exactly what the camera found - liner condition, creosote stage, cap gaps - before a single repair dollar gets discussed.
- 3
Written price and scope. We deliver a written price, written scope, and written warranty before work starts. Haven Standard Clause 1: have it in writing. No verbal quotes, no “we’ll figure it out when we get in there.”
- 4
Parts decision. We source DuraFlex OEM or equivalent quality through our Haven buying network - also HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield if the job calls for hybrid repair. We explain the trade-off and let you choose.
- 5
Repair and test. Liner replacement or rebuild proceeds. We smoke-test or pressure-test per NFPA 211. The 365-Day Done Right Promise applies from completion.
- 6
Photo record and closeout. Haven Standard Clause 4 requires a documented photo record on every job. You get the file before we leave. We clean up. You pay what was quoted.

Why Arlington Heights Homeowners Call Level Two Chimney Arlington Heights for DuraFlex Work

We don’t sell liners. We document what you have, name the failure, and quote the fix in writing. The 365-Day Done Right Promise means if it’s not done right, we make it right. Our techs are background-checked, uniformed, and carry license information on every page of their paperwork. We’ve been camera-scanning chimneys since 2009 - years before insurers asked for it - and that practice became Haven Standard Clause 4. When DuraFlex parts are back-ordered, our Haven buying network gives us same-day access to HeatShield, Gelco, and Olympia Chimney equivalents so your job doesn’t stall. Free second opinion on any competitor’s written estimate. Live phone, 24/7.
FAQs
No, proper repair by a qualified technician does not void the warranty, but using non-OEM parts or improper installation methods can. We document every repair with photos and part numbers so you have a record if warranty questions arise later. As an independent DuraFlex service provider, we follow manufacturer specs for clearance, overlap, and fastening - we don’t cut corners that would compromise your coverage.
The camera decides. Localized corrosion or a single bad joint often repairs cleanly. If we find wall thinning exceeding 25% of original thickness, multiple perforations, or liner collapse, replacement is the honest call. We show you the footage and the micrometer readings, then quote both options if both are viable. Call (331) 202-2419 for a free inspection.
Yes. We stock common DuraFlex SW and Pro diameters and source through our Haven buying network. For uncommon sizes, typical lead time is 2-4 business days. If your heat is down and DuraFlex is back-ordered, we can often substitute HeatShield or Gelco equivalents that meet the same UL 1777 listing - we’ll explain the trade-off and price difference before you decide.
Most flexible liner replacements are completed in one day. Rigid systems or jobs with multiple offsets may run into a second day. Full chimney rebuilds with new liner typically take 2-3 days, weather permitting. We give you a written schedule with the price, not a vague “we’ll see how it goes.”
A compromised liner allows flue gases, including carbon monoxide, to leak into wall cavities and living spaces. In Arlington Heights, we also see accelerated masonry damage when acidic condensate reaches the brick instead of staying contained. The risk is real and specific to your chimney’s condition - which is why we start with a camera inspection, not a scare pitch. Call (331) 202-2419 for a free estimate and see what you’re dealing with.
