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 Fireplace Services in Elmhurst: What to Know First

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall) liners crack at the flex-to-rigid transition in Elmhurst’s freeze-thaw cycle. The SW’s corrugated wall is built for straight runs, but when installers in older Elmhurst bungalows near York Woods force a tight offset to clear a chimney breast, the repeated expansion from winter lows near zero and summer humidity above 80% work-hardens the stainless at the clamp point. We cut back to sound metal, install a DuraFlex-approved rigid transition with a factory expansion joint, and document the repair with camera footage showing the full circumference.
- DuraFlex Pro series develops creosote bridging in the valleys between corrugations. The Pro’s deeper corrugations improve flexibility for offset installations, but they also create low-velocity zones where Class II and III creosote (the tarry, hardened stuff) builds faster than on smooth-wall liners. We use a rotary poly chain whip sized to the Pro’s exact inner diameter - not a generic brush - and follow with a camera scan to prove the valleys are clean before we sign off.
- DuraFlex aluminum liners corrode at the rain cap when gas fireplaces vent condensate backward. Aluminum DuraFlex is rated for certain gas fireplace insert installations, but if the cap gets plugged with Elmhurst’s cottonwood seed in June or the slope is wrong, condensate pools at the top. The aluminum pits from the outside in. We replace with a stainless DuraFlex cap or, if the liner’s remaining wall thickness checks out, transition to stainless at the exposed section. We measure with a pit gauge and show you the reading.
- DuraFlex relining collars loosen where they meet terra cotta in pre-1950 Elmhurst chimneys. The collar’s compression seal depends on a round, stable flue. Terra cotta in bungalows near Salt Creek tends to shift as the freeze-thaw cycle attacks the mortar. We pull the collar, repoint with refractory mortar where the flue is sound, or recommend a full DuraFlex Pro reline if the terra cotta is spalling (flaking off in layers - we show you the camera footage). Either way, you get a written price and a photo record.
- DuraFlex fireplace inserts suffer baffle warping when homeowners burn wet oak or run gas logs at excessive input. The baffle in DuraFlex-compatible inserts directs flame pattern; when it sags, combustion efficiency drops and CO risk rises. We don’t guess - we pull the baffle, lay it on a flat surface, and measure deflection with a straightedge. Under 3/16 inch, we reset and reseal. Over that, we source OEM or quality aftermarket through our Haven buying network and install with a new gasket kit. Written warranty, Clause 1 of the Haven Standard.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers, 24/7. We ask for your DuraFlex model or series if you know it, the fireplace type (gas, wood, insert), and what you’re seeing - odd smell, draft reversal, visible rust, failed inspection.
- 2
NFPA 211 Level 2 inspection on arrival. Camera down the flue, photo record started. We document liner condition, creosote class, crown integrity, and any DuraFlex-specific wear patterns before touching a tool.
- 3
Written price, written scope, written warranty. Clause 1 of the Haven Standard - delivered before work starts. If we find something unexpected mid-job, we stop, show you the camera footage, and write a revised price. No surprises.
- 4
Parts decision: OEM or quality aftermarket. For DuraFlex, we source through our Haven buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. We explain the trade-off - OEM warranty coverage versus availability and price - and let you choose. We don’t markup parts; our labor rate covers the work.
- 5
Repair, test, and document. We complete the fireplace service, run a smoke or combustion test as appropriate, and finish the photo record. You get a copy; we keep one on file. Clause 4 of the Haven Standard, our practice since 2009.
- 6
Cleanup and 365-Day Done Right Promise. If it’s not done right, we make it right. The promise is stamped on every job.

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 our Elmhurst work involves DuraFlex products installed during the 2015-2020 relining boom. Corrine Halstead and our crew know the Pro from the SW from the aluminum gas-rated line, and we know which failures repeat in Elmhurst’s older housing stock.
Our technicians are background-checked, uniformed, and named before they arrive - you’ll get a text when they’re on the way. We also service HeatShield and Gelco systems, so if your DuraFlex installation has hybrid components or a previous owner mixed brands, we don’t need to call in another contractor.
The 365-Day Done Right Promise applies to every DuraFlex job. The Free Second Opinion applies to any competitor’s written estimate. And the photo record from your inspection stays on file as long as you own the home.
FAQs
No, routine service by an independent provider does not void a DuraFlex warranty, provided the work is done to manufacturer specifications and documented. We are an independent DuraFlex service provider, not affiliated with or authorized by DuraFlex, and we follow their installation and service manuals for warranty-safe practices. We keep photos and written scope on file if you ever need to make a claim. Call (708) 498-3199 for a free estimate.
Most DuraFlex OEM parts arrive in 3-5 business days through our Haven buying network; common items like caps, collars, and transition pieces we often stock. If your Elmhurst job can’t wait, we source quality aftermarket from Olympia Chimney or Famco with equivalent specs and explain the trade-off before you decide. Call (708) 498-3199 for a free estimate.
We repair DuraFlex-compatible fireboxes when the refractory panels are cracked but structurally intact and the steel wrapper isn’t compromised. If the wrapper is rusted through or the panels are spalling (flaking in layers), replacement is the safe choice - we show you the camera footage and give a written price for both options. Call (708) 498-3199 for a free estimate.
NFPA 211 recommends annual inspection for all chimney systems; for wood-burning DuraFlex installations in Elmhurst, we typically see enough creosote accumulation to warrant cleaning every 12-18 months depending on burn habits. Gas DuraFlex systems need annual service for valve, pilot, and venting checks, though they produce no creosote. We write a recommended interval on every report based on what the camera shows. Call (708) 498-3199 for a free estimate.
Skipped maintenance on a DuraFlex wood-burning system leads to creosote buildup that can ignite in the liner’s corrugation valleys, and corrosion at the cap or transition that admits water and damages the surrounding structure. On gas systems, deferred service risks incomplete combustion and elevated carbon monoxide. Neither failure mode announces itself - we find them with the camera during routine inspection. Call (708) 498-3199 for a free estimate.
