Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cleaning in Chicago, NY | Emberly Chimney Cleaners
We provide independent Gelco chimney cleaning and Chimney Cap & Crown - Chicago service across Chicago for homeowners whose masonry chimneys predate modern cap design. The reason our Gelco work here is different comes down to one thing: Chicago’s bungalow belt was built for coal, converted to gas, and now punishes an undersized or missing cap harder than any newer home we’ve seen. We’re Emberly Chimney Cleaners, and we’ve inspected and cleaned more than 38,000 chimneys since 2009. Call (980) 580-8641 for a written estimate before any work begins.
Why Chicago Residents Choose Us for Gelco Service
Gelco caps are specific equipment. They’re sized to flue dimensions, engineered for a particular wind load, and built from stainless steel or copper that has to sit against brick that’s been freezing and thawing for a hundred years. That’s not a generic installation, and we don’t treat it like one. We’re an independent Gelco service provider, not manufacturer-affiliated or authorized, which means our recommendations are based on what the camera shows inside your flue and what the cap looks like when we pull it, not on a sales quota.
Corrine Halstead, our owner, grew up in Inwood where chimneys were everywhere and mostly ignored. She spent years working inspection and cleaning across all five boroughs before starting Emberly, and she still shows customers the camera footage herself. In Chicago, she’s seen enough converted coal flues to know that a Gelco cap rarely fails on its own. It fails because the flue under it was sized wrong from the day the appliance was swapped in 1958. We write the price before we start, we document what we find with photos, and we don’t recommend a new cap unless we can show you why the old one is done.
Common Gelco Chimney Cleaning Problems We Solve in Chicago
- Galvanic corrosion at the cap base. We see this constantly on Chicago bungalows where an original copper flashing meets a Gelco cap with an aluminum or galvanized base. Winter road salt carried off Lake Shore Drive and the Kennedy sits in that joint, two dissimilar metals, and the cap base corrodes through in five to eight years. We remove the cap, clean the contact surface, and install the correct Gelco replacement with a barrier that prevents the reaction.
- Cap screen clogged with Stage 2 creosote. Portage Park and Bridgeport wood burners run fires from October through April. Lake Michigan keeps the air damp, the creosote builds thick, and the Gelco screen that’s supposed to keep birds out becomes a draft-killer. We pull the cap, clean the screen properly, and document the creosote classification with the camera.
- Wind-loosened caps on exposed roofs. Beverly and Morgan Park sit on some of the flattest, most open ground in the city. Lake-effect storms hit those roofs without the tree cover or building density you get in Lakeview or Lincoln Park. Gelco caps on those chimneys work loose at the mounting bolts, and we re-seat them before they lift entirely.
- Ice damming around the cap skirt. Chicago’s freeze-thaw cycle is relentless. Temperatures hover near freezing for weeks at a time, water seeps under the cap skirt, freezes, expands, and cracks the crown mortar underneath. We see the pattern in every neighborhood, but it’s worst on bungalows where the chimney runs up an exterior wall with no heat to warm the masonry.
- Multi-flue undersizing from the coal era. A 1922 Chicago bungalow chimney was built for coal smoke, which meant broad tile flues and no cap at all. When the gas conversion happened, the appliance got smaller but the flue didn’t. A Gelco multi-flue cap that covers the old dimensions often leaves gaps, and birds and rain get into the entire chase. We measure each flue independently and size the cap to what’s actually there.
BeforeAfterGelco Service in Chicago: What Local Conditions Mean for Your Equipment
Here’s what a generic Gelco page never tells you about Chicago. The bungalow belt, roughly 80,000 brick homes built between 1910 and 1950 across Portage Park, Bridgeport, Beverly, and the surrounding neighborhoods, has chimneys originally dimensioned for coal combustion. Those chimneys were converted to gas mid-century, often without relining. What this means for your Gelco cap is simple: the flue underneath it is oversized for the appliance venting into it. Gas exhaust cools too quickly in that big tile flue, condenses, and pools acidic water that eats mortar joints from the inside. The cap you bought to keep rain out can’t fix what’s happening below it. We find this on nearly every chimney cleaning in the bungalow belt, and it’s why we always camera-scan the flue when we pull a Gelco cap for cleaning. The cap is often the first clue that the flue itself needs attention.
Gelco Models & Products We Service in Chicago
We service the full Gelco lineup: the Multi-Flue Chimney Cap, Single-Flue Chimney Cap, Copper Chimney Cap, and Stainless Steel Chimney Cap. When a cap needs replacement, we prefer genuine Gelco because their screen gauge and fit are matched to the wind and wildlife conditions we actually see in Chicago. We don’t patch a bent or corroded cap, because a $200 replacement is cheaper than the water and pigeon damage it prevents. We keep common Gelco model dimensions in local stock for faster Chicago turnaround, and when a cap is damaged beyond economical repair, we tell you that plainly and quote the correct replacement. Our materials come through Haven’s buying network, which keeps prices honest without cutting corners on the part itself.
Gelco Service Pricing in Chicago
A chimney cleaning with camera inspection in Chicago typically runs $189 to $329, depending on flue count, creosote classification, and roof access on pre-war brick. Gelco cap inspection is included when we’re already on the roof for the sweep. A new Gelco stainless steel single-flue cap installed in Chicago generally lands between $325 and $575, and a multi-flue cap to cover a converted bungalow chase runs $550 to $900 installed. The variables are flue size, roof pitch, and whether the crown needs repair before the cap can seat properly. We write every one of these numbers down before work starts, no exceptions, and the estimate includes the camera footage we’ll hand you when it’s done. Call (980) 580-8641 and we’ll put the exact price for your chimney in writing.

FAQs - Gelco Chimney Cleaning in Chicago
Because the chimney they sit on was built for coal, converted to gas without relining, and now produces acidic condensate that corrodes the cap base from below while road salt and freeze-thaw cycles attack it from above. A cap on a properly sized, relined flue in a newer home doesn’t face that chemical load. If your Gelco cap is rusting through at the base, the cap is telling you something about the flue underneath it. Call (980) 580-8641 and we’ll show you the camera footage.
Yes, but not every multi-flue cap can. Some Gelco models are built for flues that terminate at roughly the same elevation, which is rare in coal-era Chicago chimneys where one flue may serve an active furnace and another sits abandoned at a different height. We measure both flues before recommending a cap, and if a standard Gelco multi-flue won’t seal properly, we’ll say so rather than install something that leaks. The goal is a cap that covers the chase without creating a new gap.
Most of the time, yes. The cap sits on top of the flue tile, and to run the brush and camera through, we need to lift it off. That’s a normal part of the sweep, not an extra charge, and it gives us a chance to check the cap base, screen, and mounting bolts while we’re up there. If the cap is corroded or the screen is clogged, we’ll show you before it goes back on.
A properly installed Gelco cap holds up well, but the crown underneath it takes the beating. Water that finds its way under the cap skirt freezes, expands, and cracks the mortar. That’s why we check the crown every time we pull a cap for cleaning. In neighborhoods like Beverly and Morgan Park, where the wind drives rain against the chimney, we recommend a crown seal that’s compatible with the Gelco cap base, and we document the crown condition with photos before and after.
It usually means the flue is oversized for the gas appliance venting into it, and the resulting condensation has been pooling at the cap base long enough to eat through the metal. We saw this in Portage Park recently, where a Gelco stainless cap was rusted through at the base while the fireplace flue next to it looked fine. The problem wasn’t the cap, it was the flue sizing underneath it. We replaced the cap and recommended a flue inspection before the next heating season. Call (980) 580-8641 if you suspect your cap is telling the same story.
