Gelco Chimney Cleaning in Uptown, IL | Sandstone Chimney Sweep
We clean, inspect, and repair Gelco fireplace inserts throughout Uptown, and we do it as an independent service provider, not a manufacturer-authorized shop. What makes our Gelco work different here is the flue tracing: in Uptown’s courtyard buildings, a Gelco insert in one unit usually shares a masonry stack with furnace flues from four or five other units, and you can’t clean anything responsibly until you know exactly which clay flue belongs to which fireplace. Norm Sobieski and our crew handle that mapping on every multi-flue job. If your Gelco insert needs a sweep or a level 2 inspection in the 60640 zip code, call (833) 589-7835.
Why Uptown Residents Choose Us for Gelco Service
Most chimney companies in Chicago treat a Gelco insert like any other wood-burning unit. We don’t, because we’ve spent years pulling these inserts out of Uptown’s greystones and brick two-flats and seeing what a century-old shared clay flue does to them. The damper that seizes, the firebox panel that cracks, the gasket that rots away, those failures usually trace back to condensate from furnace exhaust running up the same stack, not to anything the insert did wrong. That’s the kind of diagnosis you only get from a sweep who works this housing stock week after week.
We’re an independent Gelco service provider. We say that plainly because it matters: we’re not pushing a manufacturer’s line, and we’re not going to tell you a repair makes sense when it doesn’t. We fit OEM Gelco parts when the model still has factory support, and we move to solid aftermarket equivalents only when OEM is gone. If the firebox is gone or the flue connection has opened up, we’ll tell you straight whether that insert should be repaired or pulled before it compromises the shared stack.
Norm grew up in Albany Park and learned the mechanical side of this trade at Truman College before doing residential chimney work across Chicago’s northwest neighborhoods. He still lives in a 1920s bungalow himself, so he knows what these old buildings do to fireplaces. When we trace a flue bank in a courtyard building off Lawrence, we’re not guessing, we’re mapping.

Common Gelco Chimney Cleaning Problems We Solve in Uptown
- Seized or warped insert dampers. Uptown’s lakefront winters mean furnaces run hard from October through April, and the acidic condensate from that furnace exhaust attacks damper assemblies in shared stacks. We free or replace seized Gelco dampers and, where the flue itself is spalling, we document what caused the failure so the fix isn’t just a temporary one.
- Insert-to-flue connections that have opened up. When the original clay tile in a 1920s greystone starts shedding pieces, the connection between a Gelco insert and the flue pulls apart. You may not see it from the firebox, but a level 2 camera inspection finds it. We inspect the connection, not just the firebox, on every Gelco job in Uptown.
- Cracked firebox refractory panels. Gelco inserts tied into original clay flues that were resized, or shared across units without a proper liner, run hotter and uneven on the refractory. Cracks show up sooner than they should. We replace refractory panels with materials matched to the unit.
- Glass door gaskets and hinges degraded from years of neglect. Rear-porch access is the norm in Uptown’s courtyard buildings, which means some Gelco inserts sit unserviced for years. Gaskets go flat, hinges corrode, and air leaks into the firebox. We rebuild door assemblies so the insert actually drafts the way Gelco designed it to.
- Multi-flue caps missing or undersized on shared stacks. Rain and Chicago wind get into an uncapped bank of clay flues fast, and the unit that suffers first is the one with a fireplace. We install multi-flue caps sized correctly for the whole stack, not just one opening.
Gelco Service in Uptown: What Local Conditions Mean for Your Equipment
Here’s the thing most sweep companies miss in Uptown: in the courtyard buildings off Lawrence and Argyle, the chimney is not one flue. It’s a bank of several clay tiles, often three to six, all sharing one masonry stack and serving different units in the building. Before we touch a Gelco insert in one of these buildings, we trace and label which flue serves which unit, and we map the entire stack. Most of these buildings have never had a flue map done, so when a furnace tech or a previous sweep worked on one flue, they were working blind on the others. We’re not going to clean a Gelco insert until we know exactly where its flue runs and what else it’s sharing stack space with, because cleaning a flue that’s been mislabeled, or worse, opening a damper on the wrong unit, creates a hazard no one in that building should have to live with. That flue map also tells us if the Gelco insert is venting through spalled tile or an unlined flue, which changes whether a basic cleaning is safe or whether we need to have a straight conversation about relining before anyone burns another fire.
Gelco Models & Products We Service in Uptown
We work on Gelco wood-burning fireplace inserts, Gelco glass-door fireplace units, Gelco damper assemblies, and Gelco fireplace grates and accessory lines. When a part still has OEM factory support, we use the Gelco part. When it doesn’t, we’re careful about what we substitute, because a damper or gasket that isn’t matched to the unit will fail early in Uptown’s condensate-heavy stacks. We keep common gasket sizes and damper components on the truck for the Gelco units we see most often in 60640, which means fewer return trips when a repair can’t wait. For larger jobs, a level 2 inspection, a refractory replacement, or a multi-flue cap install on a courtyard stack, we quote the full scope before we start and you see the camera footage with us.

AfterGelco Service Pricing in Uptown
| Service | Typical Range in Uptown |
|---|---|
| Gelco insert sweep (single flue, confirmed access) | $180 – $300 |
| Level 2 camera inspection (multi-flue, courtyard stack mapping) | $350 – $750 |
| Damper repair or replacement (OEM or matched aftermarket) | $140 – $500 |
| Firebox refractory panel replacement | $300 – $900 |
| Multi-flue cap supply and install | $250 – $800 |
Several Uptown factors push pricing toward the upper end: rear-porch roof access instead of a ground ladder, flue tracing across multiple units, and the condition of a century-old stack that has never had a flue map. A basic sweep on a confirmed single flue stays modest. A level 2 inspection on a six-flue courtyard stack takes time and earns its cost. Your free estimate includes the access assessment and an honest read on what actually needs doing versus what can safely wait. Call (833) 589-7835 to schedule.

FAQs – Gelco Chimney Cleaning in Uptown
Because in these buildings, your Gelco insert rarely vents through its own dedicated flue. It shares a masonry stack with furnace flues from other units, and if we don’t trace and label which clay flue serves your fireplace, we risk cleaning the wrong flue or, worse, opening a damper on a unit we weren’t hired to touch. The mapping is the safety step on every multi-flue job. Call (833) 589-7835 and we’ll walk you through what the tracing looks like on your building’s stack.
Condensate is the culprit. Your furnace runs constantly through a Chicago lakeside winter, and the acidic exhaust it pushes up the shared stack condenses inside the flue and works its way into damper assemblies. It’s not creosote, it’s corrosion, and it happens even on inserts that never burn a log. We clean and free the damper where possible, and if it’s warped, we replace it with an OEM Gelco part or a matched equivalent. A free estimate gets you a straight answer: call (833) 589-7835.
It can, but it shouldn’t long-term. Clay tile in these greystones is often spalling from decades of furnace condensate, and a Gas or wood fire exhaust moving through a cracked, unlined flue is a known fire and carbon monoxide risk. We won’t quote a relining on a scare, but we will show you the camera footage and let you decide with your own eyes. If the tile is sound, a sweep and proper cap get you through the season. Call (833) 589-7835 for a level 2 inspection.
A multi-flue cap covers the entire masonry crown and all the flues in the bank, not just the one serving your Gelco insert. We measure the full stack, fabricate or source the cap to fit, and install it so rain and debris stay out of every flue in the building. This is one of those jobs where the whole building benefits from one repair, so we often coordinate with the property owner or association. Call (833) 589-7835 and we’ll assess the stack and quote the job.
Yes. Rear-porch access is how we reach most of the courtyard buildings in Uptown, and we’re set up for it. We inspect the insert and its flue connection from the firebox side and the stack side, and we’ll camera the flue to see what years of neglect have done inside. On a recent job off Argyle, we pulled a Gelco insert that hadn’t been touched in years, repaired the seized damper and cracked refractory, then documented the spalled shared flue and flagged it for relining instead of just sweeping and leaving — the same careful approach we bring to Gelco repair in Edgewater. That’s the same level of honesty you’ll get on your building. Call (833) 589-7835.
