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 Logan Square, IL | Wexford Chimney Sweep
We provide independent DuraFlex chimney cleaning and service across Logan Square, and the one thing that makes our work here different is that we understand shared stacks. Most DuraFlex liners in this neighborhood run through brick chimneys that serve two or three flats, which means the cap, top plate, and liner connections have to be checked as a system, not as a single flue. We’re Norm Sulecki’s crew at Wexford Chimney Sweep, and we’ve been working on these greystones and workers’ cottages since well before flex liners became the standard retrofit. Call (866) 361-2607 when you want a sweep who actually knows Logan Square’s chimneys.
Why Logan Square Residents Choose Us for DuraFlex Service
We work on DuraFlex sales & service every week, so the product line isn’t a sideline for us. DuraFlex SW, DuraFlex Pro, their caps and tees, the appliance connectors: our techs handle them daily. What that means for you in Logan Square is that when we clean a DuraFlex liner, we’re also checking the hardware the way someone who installs and repairs it would. Norm grew up a few blocks from the Hawthorne Race Course in Cicero and picked up heating systems and venting at Triton College before going out on his own. Two decades later, he still runs every inspection by the same rule: tell the homeowner what’s actually there, not what pads the ticket.
You can find generic sweep services that’ll run a brush through your flue. Fewer of them will notice a loose top plate on a shared greystone stack before it becomes a carbon monoxide problem for the unit above you.

Common DuraFlex Chimney Cleaning Problems We Solve in Logan Square
- Flex liner installed in an oversized coal-era flue without insulation or a secure top plate. This is the big one in Logan Square. Those 1890s-to-1920s brick flues were built for coal furnaces, and they’re wider than what a modern gas boiler needs. We regularly find DuraFlex liners that were dropped in without proper insulation or a sealed top plate, which lets the liner shift. Flue gas then bypasses into adjacent unlined channels in the shared stack. We pull the liner, inspect it, and reset it correctly when it’s still sound.
- Cap and top-plate hardware loosened by freeze-thaw on exposed greystone crowns. Logan Square winters are hard on masonry. Water gets into crown cracks, freezes, expands, and pries cap hardware loose. By spring, you’ve got rain and snowmelt running down the outside of the liner into your flue. We replace the cap, seal the top plate, and coat the crown when needed.
- Tee and appliance connector joints corroding at the boiler or fireplace. We see this especially where a DuraFlex liner sized for a coal-era flue now vents a modern gas boiler. The connector joints take the brunt of condensation and acidic exhaust. If they’re loose or corroded, exhaust isn’t leaving your house the way it should.
- Liner bottoms crushed or distorted during installation in tight, irregular brick flues. Logan Square’s original chimneys are rarely straight. A flex liner forced through an offset or tight bend can crush at the bottom, creating a creosote and soot trap that no brush can reach. We find these with cameras, not guesswork.
- Missing or failed multi-flue caps on shared stacks. When one stack serves three flats, every channel needs to be sealed, not just the one with a liner. A missing cap over an open channel lets rain, birds, and debris in. We install multi-flue caps sized to the whole stack.
DuraFlex Service in Logan Square: What Local Conditions Mean for Your Equipment
Walk down any block near the Logan Square monument and you’ll see the same thing: a single brick stack rising from a three-flat greystone, with mortar that hasn’t been pointed since the Eisenhower administration. The telltale Logan Square chimney is one stack serving two or three units, and each unit often has its own separate, unlined flue channel. Here’s the problem that a generic DuraFlex page will never tell you: a DuraFlex liner properly connected in one flat can still leave the neighboring channels open. So when we clean your liner, we’re also checking whether the cap and top plate actually seal every channel in that stack. If they don’t, the flat next door is pulling air through a flue that’s not sealed at the top, and your liner is only doing half its job. We inspect from the roof because that’s where the answer is. The density of these older buildings also means furnace run times are long from November through March, which accelerates creosote build-up in wood-burning flues and corrosion in gas venting. A DuraFlex liner in Logan Square works harder than the same liner in a suburban single-family house.
DuraFlex Models & Products We Service in Logan Square
We clean, inspect, and repair DuraFlex SW single-wall stainless flex liner kits, DuraFlex Pro flexible chimney liners, the DuraFlex Rain Cap and Deluxe Cap line, and DuraFlex appliance connectors and tee assemblies for both gas and wood appliances. We fit OEM DuraFlex components when a top plate, cap, or tee needs a matched replacement, and we’ll use quality aftermarket stainless hardware when the OEM part isn’t the right fit for an odd flue. We don’t carry hardware-store substitutes. We stock the common DuraFlex parts, which means most Logan Square repairs go in a single visit instead of waiting on a parts order.

FAQs – DuraFlex Chimney Cleaning in Logan Square
Yes, one unit’s flue can be lined with DuraFlex while the other channels remain unlined, but the cap and top plate have to seal every channel in the stack. We’ve seen too many jobs where a liner went in without a proper multi-flue cap, and the open channels became a path for water and exhaust. Call (866) 361-2607 and we’ll inspect the whole stack, not just your unit’s opening.
We replace it and address whatever caused it to fail. In Logan Square that’s usually freeze-thaw on an exposed greystone crown, so we’ll check the crown and top plate at the same time. If the cap is an OEM DuraFlex unit, we’ll match it. Call (866) 361-2607 for a free estimate.
You don’t, not without a camera. The signs of a bad install are exactly what we look for during a Level 2 inspection: liner shifting in an oversized flue, a missing or poorly sealed top plate, crushed sections at tight bends. In Logan Square’s 1890s-to-1920s chimneys, these issues are common enough that we recommend a camera inspection whenever you buy a building with an existing liner.
It can be. Coal-era flues are wider than what a modern gas boiler needs, and if the liner wasn’t properly sized and insulated, condensation and corrosion follow. The tee and connector joints are usually the first things to fail. We’ll camera the full run and tell you what’s actually going on before recommending any repair.
We repair a sound liner and its connections before quoting a full reline. But if the liner bottom is crushed, corroded through, or distorted beyond what hardware can fix, we’ll tell you plainly that it’s past saving. A clean flue isn’t a luxury – it’s just how the thing is supposed to work. So if it can’t work, we’ll say so. Call (866) 361-2607 if you want an honest read on your liner.
