DuraFlex Chimney Cleaning in Chicago Loop, IL | Wexford Chimney Sweep
We provide independent DuraFlex chimney cleaning and repair across Chicago Loop, from 60695 and the surrounding commercial towers, and also offer DuraFlex service in Near South Side. What makes our DuraFlex work different here is practical: we know how to get equipment to a rooftop penthouse when the building has no exterior ladder access. If you own or manage a building with a DuraFlex liner in the Chicago Loop, call (866) 361-2607 and we’ll tell you exactly what the job involves before we book anything.
Wexford Chimney Sweep has spent years pulling, inspecting, and repairing DuraFlex prefab stainless chimney systems in the Loop’s commercial towers and landmark buildings. We know how their twist-lock joints, support brackets, and termination caps actually behave when installed in downtown mechanical shafts. Because we’re independent, not manufacturer-affiliated or authorized, we diagnose the actual DuraFlex components on your roof rather than steering you toward a single manufacturer’s replacement. For all DuraFlex sales & service, we start with what’s there, not what’s easiest to sell.
Why Chicago Loop Residents Choose Us for DuraFlex Service
Most chimney companies in this area see a stainless liner and treat it like any other pipe. DuraFlex systems in Chicago Loop buildings have their own failure patterns, and Norm Sulecki, our owner, has been reading them for going on two decades. He grew up near the Hawthorne Race Course in Cicero, picked up the fundamentals of heating and venting at Triton College, and built Wexford around honest inspections: the technician tells you what’s actually wrong with the flue, not just what generates a bigger bill.
We serve Chicago Loop service area buildings with a simple approach: sweep it, inspect it, and if something’s wrong, we fix it. We stock genuine DuraFlex components for common Loop repairs so we’re not waiting on a parts shipment while a shared commercial flue sits out of service. One company for your chimney and your dryer vent, both of which are fire risks in dense masonry buildings. Both deserve a specialist who knows the difference between a liner that needs cleaning and one that’s actually failed.

Common DuraFlex Chimney Cleaning Problems We Solve in Chicago Loop
- Twist-lock joint separation inside tall mechanical shafts. In Loop high-rises, liner runs can be eighty feet or more, threaded through interior shafts that shift slightly with the building. That movement works twist-lock and band-clamp joints loose over time. When a joint separates, flue gas and soot escape between liner sections, and you smell it in tenant spaces. We pull, resecure, and sweep the full run.
- Corrosion pitting at the top section under the termination cap. Lake-effect moisture and freeze-thaw cycles in Chicago hit the top few feet of a DuraFlex liner hardest. We find pinhole corrosion there more often in Loop buildings than anywhere else we work, because the rooftop exposure is relentless and the cap seals don’t always drain snowmelt away from the liner mouth.
- Kinked or compressed liner sections from tight historic light-well offsets. Older Loop towers, especially pre-1930s ones, have chimney stacks threaded through interior light wells with some awkward offsets. A flexible DuraFlex liner that was pulled through those offsets years ago can develop compression points that trap creosote. We spot them with a Level 2 inspection and clean the traps without forcing the liner further.
- Loose or degraded top plate and cap seals after ice damming. Chicago Loop’s flat and low-slope roofs hold snowmelt, and when it refreezes, ice dams drive water into chimney tops. The top plate seal is usually the first thing to go. Water tracks down the outside of the liner, soaking flue insulation and causing hidden corrosion. We reseal the cap and top plate before the heating season gets going.
- Soot and grease buildup in shared commercial cooking flues. Most DuraFlex liners we service in the Loop vent restaurant or hotel kitchen equipment, not residential fireplaces. That flue has to be cleaned on an aggressive schedule to meet city fire codes. We handle scheduled commercial sweeps and the paper trail that building engineers and fire marshals want to see.
DuraFlex Service in Chicago Loop: What Local Conditions Mean for Your Equipment
The single biggest factor in Loop DuraFlex work isn’t the liner itself. It’s access. Many of the historic towers along the Wabash Avenue corridor and elsewhere in the district have no exterior ladder route to their chimney stacks, so the job starts by booking freight-elevator time with the building engineer, then hauling cleaning equipment through a mechanical penthouse to the roof. A flexible DuraFlex liner in one of those towers can only be inspected and swept after that vertical access is arranged. It shapes how we sequence everything: we coordinate the elevator, then the roof, then the actual flue work, because arriving at a Loop building without access sorted just means a technician standing in the lobby with a brush and a schedule that’s already slipping.
That’s the difference between a company that occasionally works downtown and one that knows the rhythm of it. On a pre-1930s terra-cotta-clad tower near the Wabash Avenue corridor, we booked freight-elevator time with the building engineer to reach a rooftop penthouse serving a shared commercial cooking flue. The DuraFlex flexible liner had a separated band-clamp joint two sections down, trapping soot and letting smoke drift between tenants, so we pulled the liner, cleaned the run, resecured the joint, and resealed the top plate and cap before the heating season. The physical cleaning took a couple hours. The access coordination took half a day. That’s Loop chimney work in a sentence.

AfterDuraFlex Service Pricing in Chicago Loop
What drives the cost of a DuraFlex cleaning or repair in the Chicago Loop isn’t usually the liner work itself. It’s access. Freight-elevator coordination, building engineer time, and rooftop penthouse logistics all add labor hours before we touch the flue. A basic sweep on an accessible roof runs on the lower end; a sweep that requires freight-elevator scheduling and coordination across tenants runs higher. When we give a free estimate, we break that access cost out separately so you see exactly what’s chimney work and what’s logistics. A Level 2 Inspection, cap replacement, or soot removal all get quoted the same way, before any work is booked. Call (866) 361-2607 for a free estimate. We’ll tell you what the job needs and what it’s going to cost.

FAQs – DuraFlex Chimney Cleaning in Chicago Loop
Yes, in most Loop buildings that’s exactly what we need. Where there’s no exterior ladder access to the chimney stack, we schedule freight-elevator time with building management and coordinate with the building engineer to get our equipment to the rooftop penthouse. The flue cleaning itself is straightforward; getting to it is the part that has to be planned. Call (866) 361-2607 and we’ll walk through what your building requires.
Tall mechanical shafts move slightly with building settlement and thermal expansion, and those forces concentrate at the twist-lock and band-clamp joints between liner sections. Over years, that movement loosens clamps until a joint separates. The separation lets flue gas and soot escape between sections, which is what you smell in tenant spaces. We fix it by pulling the liner, cleaning the run, and resecuring the joints.
Yes. Most of the DuraFlex liners we clean in the Chicago Loop serve hotel and restaurant kitchen exhaust, and those flues run on strict city fire-code schedules. We handle recurring commercial sweeps, document each cleaning for building engineers and fire marshals, and flag any grease or creosote buildup that would put the next inspection at risk. Call (866) 361-2607 to set a schedule that matches your building’s requirements.
We start at the top plate and cap. Ice damming on flat Loop roofs forces snowmelt into the chimney top, and the top plate seal is usually the first thing to degrade. We check the seal, the cap’s drip edge, and the top few feet of the liner for corrosion pitting caused by trapped moisture. If the cap is damaged, we replace it; if the seal is the problem, we re-seat and reseal it. Call (866) 361-2607 and we’ll inspect it properly.
We repair what’s repairable and replace what isn’t. Localized joint separation, cap corrosion, or top plate failure gets repaired with genuine DuraFlex components where they match. We don’t push a full reline when the liner itself is still sound. A full replacement only makes sense when the liner walls are thinned by corrosion or the structural integrity is compromised, and we’ll show you the camera evidence before we recommend that. Call (866) 361-2607 for an honest read on what your liner actually needs.
