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 Lincoln Park, IL | Sandstone Chimney Sweep
We provide independent DuraFlex chimney cleaning and relining service across Lincoln Park, including 60614, and also offer our Chimney Sweep in Lincoln Park. The work here is different from most neighborhoods: in Lincoln Park’s 1880s – 1920s greystones and brownstones, a single chimney often carries multiple flues serving different appliances, sometimes different condo units entirely. Before a brush goes in, we camera-map and identify each flue so the right liner gets cleaned and the right owner gets the report. Call (833) 589-7835 to book a DuraFlex inspection and sweep.
We’re Sandstone Chimney Sweep, and we’ve spent years working on DuraFlex sales & service systems inside converted century-old masonry throughout Lincoln Park. We stock genuine DuraFlex components locally, which means less waiting when a top plate, tee, or liner section needs replacing. Norm Sobieski, our owner, learned building systems at Truman College and still lives on the North Side, so he knows what these old chimneys put a liner through.
Why Lincoln Park Residents Choose Us for DuraFlex Service
Most sweep companies in DuraFlex repair in Chicago Loop and elsewhere can run a brush up a flue. Far fewer can tell you whether the DuraFlex liner inside that flue is still doing its job. In Lincoln Park, where so many fireplaces were converted to gas and the original masonry chimneys were relined piecemeal over decades, that distinction matters. We’re OEM-fluent: we know how DuraFlex SW single-wall sections behave inside a tight greystone flue, how ProFit pre-insulated runs hold up against cracked tile and old mortar, and where terminations fail when Lake Michigan moisture works on them every winter. We use genuine DuraFlex components for repairs because mixing liner brands is how connections fail.
We also do something most contractors won’t: we tell you when your liner doesn’t need replacing. A clean flue isn’t a luxury – it’s just what a working fireplace requires. If the liner is sound, we clean it, re-terminate it properly, and tell you to call us again next year. If it’s crushed, corroded, or undersized, we’ll show you the camera footage before we quote anything.

Common DuraFlex Chimney Cleaning Problems We Solve in Lincoln Park
DuraFlex liners are built well. The problems we see in Lincoln Park usually aren’t material defects. They’re what happens when a good product gets installed wrong, or when a century of Chicago weather works on the chimney around it. Here’s what we deal with most:
- Crushed or kinked flexible liner sections inside tight offset flues. Lincoln Park’s greystone chimneys weren’t built for stainless liners. They were built for coal smoke, with narrow throats and offset passages. When a retrofit gets forced through, the DuraFlex section can crush to an oval, which chokes draft for whatever appliance vents through it. That alone can justify a camera inspection.
- Liner-to-cap and liner-to-appliance connections that were never sealed correctly. Lake moisture and freeze-thaw condensation sit on those joints. We’ve pulled top sections with rust blooms at the connection and clean stainless twenty feet below. It’s always the joint. OEM top plates and proper termination fix it.
- Torn insulation wrap on pre-insulated DuraFlex runs. Inside a rebuilt chimney, the wrap can shred against cracked flue tile or old mortar. Once the insulation gap opens, the liner overheats against the masonry. It still looks fine from the top down, which is why we camera the full run.
- Liners cut short at the crown after a conversion. A lot of Lincoln Park flues that once served coal fireplaces now vent gas furnaces. When the original crown was rebuilt and the liner was cut short, spalling brick and mortar grit drop onto the liner and water wicks down the annulus. A proper multi-flue cap and termination solves most of it.
- Shared chimneys with mixed liner types and no flue map. In two- and three-flat greystones, one chimney stack may have a DuraFlex liner serving a furnace, a clay tile flue serving a fireplace, and a water heater vent sharing the space. We map each flue before any brushing so the correct liner gets cleaned and the correct unit owner gets the report.
DuraFlex Service in Lincoln Park: What Local Conditions Mean for Your Equipment
Here’s the thing about Lincoln Park that a generic DuraFlex page never tells you. In the greystone and brownstone blocks off Fullerton and Armitage, a single chimney often carries more than one DuraFlex or legacy liner serving different appliances and sometimes different condo units. We’ve been inside three-flats where two owners shared one stack and neither could say which flue belonged to whom. So before a brush goes in, we map and camera each flue. That’s not a upsell. It’s the only way to know which liner is yours, which one has the furnace exhaust, and which one needs the work. On a two-flat off Fullerton, a homeowner’s “annual cleaning” turned into discovering a gas furnace tied into an old fireplace chimney with a DuraFlex liner crushed to an oval by a cramped offset. We camera-mapped the stack, confirmed the liner was shot, and set the owner up with a correctly sized, insulated run plus a proper top plate and multi-flue cap so each appliance vented cleanly. The sweep became a reline, but it was the right call. That liner wasn’t going to survive another Chicago winter.
DuraFlex Models & Products We Service in Lincoln Park
We work on the full DuraFlex stainless relining range you’ll find inside Lincoln Park’s converted masonry chimneys: DuraFlex SW single-wall kits, DuraFlex Pro and ProFit pre-insulated flexible liner systems, DuraFlex Direct Vent and appliance venting components, and the oval and round rigid-and-flex hybrid runs used in masonry fireplaces. When a repair is needed, we use genuine DuraFlex OEM liner sections, tees, top plates, and caps. Aftermarket sections may look interchangeable, but the fit tolerances on flexible stainless are tight. A brand-mixed connection is where leaks start. Since we’re independent and not authorized by DuraFlex, our parts sourcing is our own decision, and we choose OEM because we’ve seen what knocks-off joints do inside a wet greystone flue.

FAQs – DuraFlex Chimney Cleaning in Lincoln Park
It depends on the liner’s condition and whether it’s the right size and type for the furnace’s exhaust. Gas furnace exhaust is cooler and wetter than wood smoke, which means condensation sits on the liner longer. If the DuraFlex section is intact, properly sized, and terminated correctly at the crown, it’s generally safe. If it’s crushed, corroded at the joints, or cut short, it isn’t. The only way to know is a camera inspection. Call (833) 589-7835 and we’ll map the flue and show you the footage.
Without a flue map, nobody’s. We camera each flue from the roof down and from the appliance connection up, then mark which liner serves which unit and which appliance. That report becomes the reference for both owners. It also prevents us from cleaning the wrong flue, which happens more often in Lincoln Park three-flats than anyone wants to admit. Call (833) 589-7835 to schedule a mapping and Level 2 inspection for your shared stack.
Yes, if it’s installed correctly and terminated properly. The liner itself is stainless and handles moisture. What fails is the system around it: connections that weren’t sealed, insulation wrap that tore, crowns that shed brick grit onto the top plate. Lincoln Park’s lake-driven humidity and hard freezes accelerate those failures. Annual cleaning gives us a chance to inspect the full run before small issues become liner replacement. Call (833) 589-7835 to book a sweep and condition check.
A routine sweep removes creosote and soot. A Level 2 inspection cameras the entire flue from the crown to the appliance connection, checks the liner’s structural condition, confirms proper termination, and documents any gaps, crushed sections, or corrosion with photos and video you can review. For a DuraFlex liner inside a converted greystone, that camera pass is what tells us whether the liner is still doing its job or whether it’s time to talk replacement. Call (833) 589-7835 to schedule both.
Sometimes. If the rest of the liner is sound and the damage is limited to the top section at the crown, we can cut and splice a new OEM section with a proper liner coupling and re-terminate it. We’ll show you the camera footage on both sides of that decision. If the lower sections show corrosion or crush damage, a partial patch just moves the failure point down. We’ll tell you straight which it is. Call (833) 589-7835 for a camera assessment.
