We provide independent DuraFlex chimney cleaning, inspection, and repair across Mount Greenwood’s 60655 ZIP code.

Why Mount Greenwood Residents Choose Us for DuraFlex Service
Mount Greenwood is a neighborhood of owner-occupied bungalows and two-flats, and most of the chimneys we work on have been in the same family for decades. That changes how a sweep gets done. Homeowners here want someone who can explain creosote buildup without making it sound like the house is about to burn down, and they want a straight answer on whether a liner repair can wait or needs attention before the next burn. Norm Sobieski, owner of Mount Greenwood Chimney Sweep, grew up on Chicago’s North Side watching his grandfather tend a coal-converted fireplace every winter, and he learned the mechanical side of this trade through the HVAC and building systems program at Truman College. He brings that same plain-spoken approach to every chimney in Mount Greenwood.
Our independent crew relies on DuraFlex sales & service knowledge built from hundreds of systems across Chicago’s southwest side. We aren’t authorized or affiliated with DuraFlex, and we don’t claim to be. We simply work with their components often enough to know what holds up and what doesn’t when a Chicago winter gets serious.

Common DuraFlex Chimney Cleaning Problems We Solve in Mount Greenwood
DuraFlex liners are built well, but no liner is immune to what an original 1920s chimney in Mount Greenwood throws at it, which is why we also provide DuraFlex repair in Merrionette Park. These are the issues we handle most often, and each one is tied to something specific about this neighborhood’s housing stock and weather.
- Spalled terra cotta tiles cracking the liner. On many blocks near 111th and Kedzie, the original flue tiles have been crumbling for decades. When those tiles shift during freeze-thaw cycles, they put pressure on the DuraFlex stainless liner inside. We see cracked insulation and dented liner walls that homeowners mistake for “just an old fireplace.”
- Missing rain caps letting southwest-side weather in. A surprising number of Mount Greenwood chimneys are missing their rain cap entirely, or the cap is corroded through. Lake-effect snow and rain pour straight down the flue, rusting the DuraFlex liner from the inside and eating away at the crown mortar.
- Improperly sized liners causing draft and creosote problems. We’ve cleaned DuraFlex systems in Mount Greenwood that were installed with the wrong diameter for the fireplace they serve. The result is weak draft, smoke backing into the living room, and creosote that builds up twice as fast as it should. Homeowners blame the wood. It’s usually the liner sizing.
- Damaged crowns and caps from winter storms. Mount Greenwood sits far enough southwest that freeze-thaw cycles hit hard from December through March. Storm-damaged DuraFlex caps and cracked crowns let water seep behind the liner, rust the stainless, and erode mortar joints that then leak into the attic.
- Corrosion at connection points. Where the DuraFlex liner connects to the appliance or the cap, we routinely find rust developing faster than anywhere else on the system. This isn’t a DuraFlex defect. It’s moisture collecting at the joints in chimneys that don’t get inspected often enough.
DuraFlex Service in Mount Greenwood: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic DuraFlex page: Mount Greenwood’s chimneys have a specific problem that changes how we approach every DuraFlex cleaning here. The housing stock near 111th and Kedzie is dominated by original 1920s brick bungalows with terra cotta flue tiles that have been spalling for decades. Freeze-thaw cycles from December through March push moisture into those old tiles, they crack and shift, and the shifting tiles put direct pressure on whatever liner is inside them. If that liner is a DuraFlex stainless system, the damage often shows up first as insulation tears and small dents that don’t look serious during a visual check. But water gets in through those tears, and water is what turns a five-year-old liner into a venting hazard. That’s why we treat every Mount Greenwood DuraFlex cleaning as an opportunity to check the liner’s condition against the condition of the chimney surrounding it. A sweep that ignores spalling tiles is missing the actual problem. We don’t miss it, because around here it’s the rule rather than the exception.

AfterDuraFlex Service Pricing in Mount Greenwood
Our DuraFlex chimney cleaning in Mount Greenwood typically runs between $180 and $340, and most of that work is completed the same day. A Level 2 inspection, which we recommend for any DuraFlex system that hasn’t been checked in a few years or that sits in one of those original 1920s chimneys near 111th and Kedzie, adds a camera scope so you can see the liner condition yourself. What drives the final cost is the liner’s length, how much creosote has accumulated, and whether we find damage during the sweep that needs repair. Nothing gets recommended unless we can show you the camera evidence. Call (833) 589-7835 for an exact quote. Estimates are free, and we won’t push a repair you can safely postpone.

FAQs – DuraFlex Chimney Cleaning in Mount Greenwood
Usually not. Spalled tiles are common in original 1920s chimneys around Mount Greenwood, and in many cases the liner is still structurally sound. What matters is whether the shifting tiles have actually cracked the DuraFlex liner or torn its insulation. We inspect with a camera before recommending anything. If the liner is intact, we may repair the crown, install a proper cap, and seal the mortar joints to stop further water damage. A full rebuild is a last resort, not a first recommendation. Call (833) 589-7835 to schedule a camera inspection and find out where your chimney actually stands.
At least once a year, and fall is the right time in Mount Greenwood. The freeze-thaw cycles from December through March are what stress the liner and the chimney around it, so you want an inspection before that cycle begins. If your chimney is older brick with terra cotta tiles, we may suggest a Level 2 inspection every other year to monitor what the shifting tiles are doing to your DuraFlex liner.
Almost every prematurely rusted DuraFlex cap we’ve replaced in Mount Greenwood traces back to one thing: standing water. A cap that’s dented from storm debris holds water against the stainless, and lake-effect snow sitting on the cap accelerates corrosion. Add Mount Greenwood’s freeze-thaw swings, and a cap that should last a decade can fail in three. The fix is replacing it with the right cap for your flue and making sure the crown slopes water away. We can tell you whether your current cap is worth salvaging.
Yes, and we do it regularly in Mount Greenwood and offer DuraFlex service in Hometown too. The DuraFlex insert liner gets swept from the top down using brushes sized to the liner’s diameter, so the creosote comes out without scraping the stainless. The important thing is that the brush matches the liner. If a sweep uses a brush sized for clay tile, it can damage the DuraFlex walls. We carry the right sizes for every DuraFlex system we service.
A Level 1 inspection is a visual check of the accessible parts of the chimney: the cap, the crown, the liner’s top section, and the firebox. A Level 2 inspection adds a camera run through the full flue length so we can see the liner’s interior condition, connection points, and any damage behind the walls. For a DuraFlex system in an older Mount Greenwood chimney, we recommend Level 2 at least every other year, because the flue is doing more work than a Level 1 can verify.
