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 Cleaning in Cicero, IL | Crossroads Chimney Sweep
DuraFlex chimney cleaning in Cicero means more than running a brush up a flue. We’re an independent DuraFlex service provider at Crossroads Chimney Sweep, not manufacturer-affiliated or authorized, and the work here mostly involves assessing liners installed in chimneys that were built for coal around 1920, not for wood. That difference shapes every inspection we do. Call (877) 265-6720 if your DuraFlex liner hasn’t been looked at in a while.
We stock genuine DuraFlex liner sections, top plates, and caps for DuraFlex sales & service work across Cicero. Our crew knows the SureFlex, SW Flex, Insulated Flex, and rigid stainless lines from field use, not from a brochure. If you’re in the 60804 ZIP code, we work your block regularly.
Why Cicero Residents Choose Us for DuraFlex Service
Most DuraFlex liners in Cicero live inside chimneys built between 1910 and 1930. Those flues were sized for coal smoke, then converted for gas furnaces and water heaters, and sometimes re-converted for wood by an owner who never asked whether the liner could take it. Norm Szczepanski, our owner, grew up on the northwest side of Chicago and has been working chimneys in Belmont Cragin, DuraFlex in Berwyn, and the surrounding neighborhoods for going on two decades. He’ll look at a DuraFlex liner the way a mechanic looks at a drivetrain, checking what’s actually there before suggesting anything.
We bring that same approach to every job in Cicero. The right material for the right repair, named brands included. If a liner needs a section replaced, we use genuine DuraFlex components where the original system is still serviceable. If it’s pitted through in multiple runs, we say so plainly. No badge on our truck says “authorized,” and that’s deliberate. Our credibility comes from pulling these liners out and seeing how they fail in this specific housing stock.

Common DuraFlex Chimney Cleaning Problems We Solve in Cicero
- Corrosion pinholes and rust streaks at the cap. Flexible DuraFlex liners installed without insulation in exterior Cicero chimneys condense flue gas during Lake Michigan freeze-thaw cycles. Those cycles are relentless here, and the result is rust streaking down the brick and pinholes near the cap. We see this on SW Flex and SureFlex installs alike.
- Loose top plates and compression joints on shifting crowns. The original 1910s-1930s brick crowns on Cicero two-flats spall and shift every winter. Older DuraFlex installs with compression-fitted joints start to loosen as that crown moves, letting water track down the liner chase. The liner itself may be fine. The termination isn’t.
- Undersized liners carrying wood heat they were never sized for. A DuraFlex liner sized for a gas water heater gets dangerously overloaded when someone starts burning wood in that flue. No insulation, coal-era soot residue, and an undersized diameter combine into a real hazard. We find this pattern constantly in Cicero.
- Liner bottoms terminating short of the appliance collar. Tight shared-party-wall chases leave little room to work, and some installs end up with a gap between liner bottom and firebox or collar. Creosote and soot collect behind the liner in that gap, invisible until a Level 2 camera finds it.
- Shared flues between units with no separation. In a Cicero courtyard building, one chimney often serves two units. A DuraFlex liner dropped for one unit’s appliance may not be separated from the neighbor’s flue. Our camera work maps which flue serves which appliance before anyone touches a cap or top plate.
DuraFlex Service in Cicero: What Local Conditions Mean for Your Equipment
Cicero’s rowhouse-density two-flats and courtyard blocks mean many DuraFlex liners run up a chimney shared between two units. That’s the single biggest difference between servicing liners here versus in a newer suburb with standalone chimneys. Before we remove a cap or top plate, our Level 2 camera has to confirm which flue serves which unit’s appliance. Get that wrong on a shared chimney off Cermak Road and you’re suddenly working on a neighbor’s gas water heater instead of the wood burner you were called for.
This is also why we don’t rush a sweep in Cicero. The chimney wasn’t built for what’s in it now. Wet Lake Michigan winters with repeated freeze-thaw cycles chew at the same aged brick crowns and unlined flues. A DuraFlex liner may be the one component in good shape while the masonry around it crumbles. Cleaning, in that situation, is half the job. Assessment is the other half. A clean flue isn’t a luxury, it’s just how the thing is supposed to work.
DuraFlex Models & Products We Service in Cicero
We work on the full range of DuraFlex stainless liners found in Cicero chimneys. That includes the SW Flex single-wall flexible relining kit, SureFlex flexible stainless liner, Insulated Flex pre-insulated liner for exterior chimneys, and rigid stainless relining sections used in straight coal-flue conversions. For repairs, we use genuine DuraFlex liner sections, top plates, and caps where the original system still makes sense to keep. When a direct OEM match isn’t practical on an old coal-flue chase, we use quality aftermarket stainless and insulation components that fit the job. One call covers it, whether you need a sweep, a repair, or a dryer vent cleaned.
If a liner is pitted through in multiple runs or the tile behind it is cracked along a shared party wall, we tell owners honestly. Relining is the only durable fix at that point. Patching a failing system just means another call next spring, and Cicero springs are busy enough already.

AfterDuraFlex Service Pricing in Cicero
DuraFlex chimney cleaning in Cicero typically starts in the $180 to $340 range for a standard sweep with a Level 1 inspection. Adding a Level 2 camera inspection runs another $200 to $450, depending on how many flues we’re mapping and whether it’s a shared chimney. A cap installation on a DuraFlex liner usually lands between $150 and $350, including the cap itself. Full liner replacement runs $2,500 to $5,000 or more, driven by flue length, insulation needs, and the condition of the existing chase. These are working numbers for the 60804 market, not a quote.

FAQs – DuraFlex Chimney Cleaning in Cicero
Almost never. A DuraFlex liner sized for a gas water heater does not have the diameter, insulation, or temperature rating to handle wood combustion. Burning wood in that flue creates a fire hazard, full stop. You’d need a properly sized insulated liner, and we’d need to check the tile behind it and the smoke chamber first. Call (877) 265-6720 and we’ll tell you exactly what your flue can handle.
Uninsulated flexible liners condense flue gas when they run through cold exterior chimney chases, and Cicero’s wet freeze-thaw winters make that condensation constant. The moisture corrodes the stainless from the inside, then shows up as rust streaks near the cap. Insulated Flex or adding proper insulation usually stops it. Call us for a camera look before the streaks become pinholes.
We map the flues first with a Level 2 camera, confirming which flue serves which unit’s appliance before we remove any cap or top plate. On a shared Cicero chimney, that step is non-negotiable. Then we clean or service only the flue we’re called for, leaving the neighbor’s appliance untouched. Call (877) 265-6720 and we’ll walk you through what your shared setup actually looks like.
Yes. We repoint and rebuild crowns around existing liners regularly, using proper mortar and crown treatment that holds up to Lake Michigan winters. The liner stays in place while we work the masonry. If the crown has shifted badly enough that the top plate is compromised, we’ll address that at the same time. We also offer DuraFlex service in Oak Park. Call (877) 265-6720 for an honest look at what the crown actually needs.
A standard sweep removes creosote and soot from the flue, then we check the liner interior with a camera. On a DuraFlex liner, we’re looking for corrosion pinholes, loose joints, gaps at the termination points, and any sign the liner was oversized, undersized, or improperly installed. The Level 1 inspection comes with the sweep. A Level 2 adds a deeper camera pass and flue mapping, which we recommend on any shared chimney in Cicero. Call (877) 265-6720 for exact pricing on your setup – estimates are free.
