Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in New City, IL | Sandstone Chimney Sweep
We provide independent Gelco chimney cleaning and insert service across New City and nearby areas like Gelco repair in Grand Boulevard, and the work here is different from what you’d get in a newer subdivision. Most Gelco units in ZIP 60609 vent into flues built for coal stoves between 1890 and 1930, so a cleaning call often turns into a diagnostic: what’s behind that insert collar, and has the original flue ever been lined? If your Gelco insert is smoking, drafting poorly, or you’ve never seen the inside of the chimney behind it, call Norm and the team at (833) 589-7835 for a straight answer.
Why New City Residents Choose Us for Gelco Service
We’ve opened hundreds of flues in New City’s brick two-flats and worker cottages, and we know how Gelco fireplaces and inserts were installed here, often retrofitted into chimneys that were built for something else entirely. That means we don’t show up to a Gelco insert call expecting a modern, lined, code-built flue. We expect original unlined brick, mortar joints softened by a century of freeze-thaw, and occasionally a sealed-off chase that hasn’t seen daylight since the Reagan administration.
Our owner, Norm Sobieski, learned the mechanical side of this trade through the building systems program at Truman College, then spent years working on residential chimneys across Chicago’s northwest neighborhoods before starting Sandstone. He still lives in Albany Park, where he grew up watching his grandfather tend a coal-converted fireplace every winter. That background matters when a New City homeowner asks us to make sense of a chimney their grandparents fed coal into. We fit OEM Gelco sales & service components where the damper, glass, or gasket is model-specific, and we keep common caps, dampers, and liner components stocked for faster New City turnaround.

Common Gelco Chimney Cleaning Problems We Solve in New City
- Dead-end chases from mid-century gas conversions. Homes all over New City had their original coal flues bricked off or mortar-capped when gas service came in. A Gelco insert retrofitted later often vents into that sealed section. Our camera finds it, and we solve it.
- Smoke backing into the room with the damper open. This usually isn’t the Gelco appliance failing. It’s the unlined coal-era flue behind it, spalled mortar packing the smoke shelf, or a liner that was never installed. We diagnose what’s actually blocking the draft.
- Rusted dampers and pitted firebox brick. Lake-effect freeze-thaw cracks the crowns above New City’s two-flats, and water runs down into the firebox area. We see Gelco dampers seized with rust every season.
- Grit and creosote dropping onto the Gelco insert. Summer humidity soaks unlined flues, spalling brick faces. That grit lands on the smoke shelf and damper seat, restricting airflow and making creosote buildup worse.
- Failed parging behind the insert collar. The appliance itself is often fine. The mortar behind it isn’t. Combustion gases and moisture attack the parging, and the homeowner smells flue gases or sees staining around the surround.
Gelco Service in New City: What Local Conditions Mean for Your Equipment
New City’s ZIP 60609 has a dense concentration of long-term owner-occupants and rental conversions, which means a Gelco insert service call here is often the first time anyone has opened the flue since the 1980s. Owners call us because the insert smokes or the damper won’t move, and our camera inspection becomes the first documentation of what’s actually behind the wall. Sometimes it’s a dead-end chase the homeowner never knew existed. Sometimes it’s original unlined brick with mortar joints that look like crumbled sand. This isn’t a cleaning job first; it’s forensic work. We map the flue, identify what was sealed when, and then we clean and repair what the camera shows us. That’s the difference between a Gelco service in McKinley Park or New City and one in a 1990s subdivision with a factory-built chase. A clean flue isn’t a luxury, it’s just what a working fireplace requires, and in New City the flue was built before your Gelco insert was ever imagined.
Gelco Models & Products We Service in New City
We work on Gelco wood-burning fireplace inserts, Gelco gas fireplace inserts, Gelco vented gas log sets, and Gelco fireplace glass door and screen assemblies. Where a damper, glass panel, or gasket is model-specific, we fit OEM Gelco parts so the tolerances match what the factory designed. Where a chimney cap, damper assembly, or liner component has an equivalent aftermarket fit and the cost difference is significant, we’ll tell you what’s genuinely equivalent and what isn’t. We stock common components for faster turnaround in New City, and every repair starts with a camera inspection so you see exactly what we see. No part gets replaced without evidence.

FAQs – Gelco Chimney Cleaning in New City
A Gelco insert that smokes with the damper open is almost never a problem with the insert itself. It’s a flue problem behind it, typically a blocked smoke shelf packed with spalled mortar, a dead-end chase from a mid-century gas conversion, or an unlined flue that can’t draft. The insert is just the venting point; the flue is what moves the smoke. Call (833) 589-7835 and we’ll run a camera before we quote anything.
We can clean and inspect it, and we’ll tell you plainly whether it’s safe to use without a liner. Many New City chimneys are original unlined brick that has softened and spalled after a century of weather. If the camera shows structural loss or gas leakage risk, we’ll quote a DuraFlex liner system and explain what it does and what it costs. We won’t clean it and pretend the liner question away.
You usually can’t know without a camera inspection. New City’s older homes often have original coal flues that were bricked off or mortar-capped during gas conversions, then forgotten. A Gelco insert retrofitted later may vent into a chase the current owner has never seen. Our level 2 camera inspection documents what’s there, what was sealed, and what it would take to bring it back into use.
Yes, and specifically from freeze-thaw cycling on exposed crowns above New City’s two-flats. Water gets into the crown, runs down into the firebox area, and rusts the damper assembly. We’ve pulled Gelco dampers in ZIP 60609 that looked like they’d been soaked for years. The fix is usually a damper replacement or repair paired with a crown seal to stop the water at the source.
Yes, creosote removal is part of the cleaning when we see glaze buildup. We inspect, remove what’s safe to remove, and document what’s left. Stage 2 or 3 creosote glaze in an unlined New City flue is a fire hazard, and we’ll tell you exactly what the camera shows before we recommend any next step. Call (833) 589-7835 if your insert hasn’t been swept in years.
