Gelco Chimney Cleaning in North Lawndale, IL | Brightway Chimney Sweep
We provide independent Gelco chimney cleaning and repair service across North Lawndale, Gelco in South Lawndale, and nearby neighborhoods, and the thing that separates our work here from a generic sweep is simple: we know these early-1900s brick two-flats and greystones were mostly built for coal, then converted to gas without proper relining. That means a Gelco cleaning in North Lawndale is rarely just about creosote, it’s about confirming the flue is actually safe for what’s burning in it now. If you own a Gelco system, call (833) 365-6591 for a free estimate from a team that sees these blocks every week.
Why North Lawndale Residents Choose Us for Gelco Service
Plenty of companies will sweep a chimney. Fewer can tell you, honestly, whether your Gelco liner is still doing its job or whether the freeze-thaw damage to your 1920s masonry means a sweep should wait until repointing happens first. We work on Gelco stainless flexible relining kits, multi-flue caps, and top-sealing dampers across North Lawndale’s courtyard apartments and two-flat rows, so we’ve learned how these components age in buildings with shared stacks and decades of deferred maintenance. Neil Borowski, our owner, grew up near Eckhart Park in West Town and spent the better part of three decades working the same kinds of chimneys he now services for our North Lawndale customers. That background matters when a Gelco cap has seized shut or a liner shows joint separation. We’re not the cheapest option on a deal site, and we don’t try to be. We’re the crew that tells you what’s actually wrong, using trade-grade parts, and fixes it without a handoff to some subcontractor. For Gelco chimney work in North Lawndale, that’s the reason people call us back. Gelco sales & service is what we do, and we do it with the same diagnostic discipline whether it’s a simple sweep or a full relining job.

Common Gelco Chimney Cleaning Problems We Solve in North Lawndale
- Joint separation in older Gelco flexible liners. Many Gelco stainless liners were installed in North Lawndale two-flats back when the surrounding brick was still relatively stable. Thirty or forty years of Chicago freeze-thaw movement later, we regularly find crushed sections or joints that have pulled apart inside the flue. A cleaning reveals it; the fix is often a replacement liner, not just a sweep.
- Seized Gelco top-sealing dampers. Humid summers followed by hard winters cause corrosion you don’t always see from the ground. A Gelco damper that won’t open or close properly sends exhaust and creosote odor back into the living space, which in a dense two-flat block becomes a neighbor problem fast, not just a nuisance in one unit.
- Cross-connected flues in converted coal chimneys. This is the one we lose sleep over. Many gas fireplace flues in North Lawndale were never relined for gas, and in early-1900s buildings they often share a chimney with the adjacent unit. A Gelco cleaning here sometimes turns into finding that your flue and your neighbor’s are not actually separated the way they should be.
- Undersized Gelco liners on coal-era flues. Some older installations used a liner sized for a much smaller appliance, or they skipped sizing entirely. When the gas fireplace runs, the draft suffers, and what should be a clean Gelco system starts spilling combustion byproducts back into the room.
- Gelco cap corrosion and crown damage. The caps on North Lawndale rooftops take direct hits from freeze-thaw spalling. We’ve pulled Gelco caps that were corroded completely shut, with the mortar around them crumbling, which means the cap has to come off before the flue can even be assessed.
Gelco Service in North Lawndale: What Local Conditions Mean for Your Equipment
Here’s the thing about North Lawndale that a generic Gelco page won’t tell you: on the 60623 blocks, many gas fireplace flues in those early-1900s two-flats were never relined for gas, and a surprising number still share a chimney with the adjacent unit. We’ve seen it enough times to treat every Gelco cleaning in North Lawndale as an unspoken Level 2 inspection. On a two-flat off South Kedzie, our tech pulled a Gelco cap that had corroded shut and found the gas fireplace flue sharing a chimney with the neighboring unit’s flue, with no liner separating them. We ran a Level 2 Inspection, swept the creosote out of the shared stack, documented the cross-connection for both owners, and fitted a proper Gelco multi-flue cap so each flue vented on its own. The freeze-thaw damage to the crown and mortar joints got flagged alongside the sweep so the repointing could be scheduled before winter hit. That’s the difference between a company that just sweeps chimneys and a chimney and dryer-venting specialist that understands how North Lawndale’s housing stock actually behaves.
Gelco Models & Products We Service in North Lawndale
We service Gelco stainless steel flexible relining kits, multi-flue and single-flue chimney caps, top-sealing damper assemblies, and fireplace inserts with their gas venting components. When we’re working on a Gelco system in North Lawndale, we fit genuine Gelco parts when the existing liner, cap, or damper can be matched. But we also know that some Gelco sizes have been discontinued, and no homeowner should face a full teardown because a manufacturer stopped making a specific component. In those cases we use quality aftermarket stainless and masonry parts that meet the same trade standards, and we explain that choice plainly before any work begins. Our parts stock for North Lawndale covers the common Gelco cap profiles and damper assemblies we see most often on 60623 rooflines, which means less waiting when the fix is straightforward.

AfterGelco Service Pricing in North Lawndale
What you’ll pay depends on what we find, and we don’t guess at that before we look. A standard Gelco chimney cleaning in North Lawndale generally runs between $189 and $259 when the flue is in serviceable shape. If we’re dealing with heavy creosote buildup, which is common in converted coal chimneys that haven’t been swept in years, expect the higher end of that range. A Level 2 camera inspection, which we recommend whenever a cross-connection is suspected or the home hasn’t been inspected in over a decade, adds $150 to $300. A Gelco top-sealing damper replacement is typically $275 to $450. Multi-flue Gelco cap installation runs $390 to $650. When a liner replacement is needed, costs start around $1 per vertical foot for a basic stainless reline but climb quickly if the masonry has to be rebuilt first. Nothing gets recommended without camera evidence you can see for yourself. Call (833) 365-6591 for a free estimate and we’ll put exact numbers on your specific flue.

FAQs – Gelco Chimney Cleaning in North Lawndale
It depends on why it’s seized. In many North Lawndale two-flats, what looks like a mechanical failure is actually corrosion from years of humid summers and cold downdrafts. We can sometimes free a Gelco cap with cleaning and adjustment. When the mechanism is corroded through or the cap has structural damage, replacement with a proper Gelco or trade-equivalent multi-flue cap is the honest fix. We’ll show you the condition on camera before you spend a dollar. Call (833) 365-6591 and we’ll take a look.
Sometimes, but not as often as people hope. A simple Gelco sweep in a 60623 greystone that has been maintained regularly can be done in about an hour and a half, start to finish. What we find more often in North Lawndale is a chimney that hasn’t been opened in years, sometimes decades, with creosote buildup, a seized cap, and brick that’s moving. We’ll tell you if yours is the quick kind, and if it’s not, you’ll see exactly why in the photos we show you. A clean chimney doesn’t announce itself, and neither does the problem you avoided by having one.
Almost always, yes. The flues in North Lawndale’s coal-era two-flats were built for a different fuel, different temperatures, and different moisture levels than a modern Gelco gas or wood insert produces. If the original flue was never relined, your Gelco insert is venting into an oversized, deteriorating passage that was never sized for it. The only way to know for sure is a camera inspection of the actual flue, not a guess from the roof.
This is the signature sign of a cross-connected flue, and it’s more common in North Lawndale than most chimney companies will admit. In dense early-1900s two-flat rows, adjacent units often share a single masonry chimney with flues that were never properly separated. When your neighbor’s fireplace runs, the pressure difference pushes their exhaust into your unit. This isn’t something to live with, and it isn’t fixed by just sweeping your side. It requires documenting the cross-connection and capping or relining so each flue vents independently.
Yes, and we’ll tell you before we start. If the brick and mortar around your Gelco cap in North Lawndale is spalling, which is accelerated by Chicago’s freeze-thaw cycles, removing the cap can loosen more material. We also handle Gelco service in West Garfield Park with the same careful approach. We may need to do targeted repointing or at least stabilize the crown before we can safely sweep and reinstall the cap. We’ll show you photos of the condition and give you a straight answer about what can wait and what can’t. For any of these situations, call (833) 365-6591 and we’ll give you a free, camera-backed estimate for your North Lawndale home.
