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 Des Plaines, IL | Duke Chimney Sweep
We provide independent Gelco chimney cleaning, inspection, and repair across Des Plaines, IL, including all four ZIP codes: 60016, 60017, 60018, and 60019. The one thing that makes our Gelco work here different is simple: most Gelco inserts in Des Plaines sit inside chimneys built in the 1950s and 60s that were never sized for an insert. We know what that means for creosote buildup, cracked clay tiles, and airflow, and we address it honestly. Call (844) 660-6510 for a free estimate.
Why Des Plaines Residents Choose Us for Gelco Service
We’ve worked on Gelco fireplace inserts and factory-built units across Des Plaines’ post-war ranches, split-levels, and brick Cape Cods for years, so we understand how these units age in this specific climate. Our approach comes from Rob Szymanowski, who grew up in Wheeling and spent enough winters near the Chevy Chase Country Club area to develop a healthy respect for what a poorly maintained chimney can do to a house. He learned the mechanical and safety fundamentals of the trade through the HVAC and building systems program at Harper College in Palatine, then spent years working chimneys and dryer vents across Cook and Lake counties before founding Duke Chimney Sweep. As an independent provider, we service Gelco equipment on its own merits, with no manufacturer authorization or warranty claim implied. We stock OEM Gelco parts where they’re still available for firebox panels, baffles, dampers, and venting components. When a discontinued piece needs replacing, we switch to quality aftermarket parts and tell you exactly what we’re using and why. That’s how we’ve built our reputation in Des Plaines: showing up on time, explaining what we found in plain English, and not inventing problems that don’t exist.

Common Gelco Chimney Cleaning Problems We Solve in Des Plaines
- Cracked clay-tile flues behind Gelco inserts. The repeated freeze-thaw cycles of Chicago-area winters stress the original clay tile joints in Des Plaines’ 1950s-60s chimneys. What starts as a routine Gelco insert sweeping turns into a Level 2 inspection when we spot cracked tiles, and then an honest conversation about whether a reline is needed before the next burning season.
- Creosote and soot packed behind 1990s gas conversions. Des Plaines saw a wave of wood-to-gas fireplace conversions in the 1990s. Many of those Gelco gas inserts were never re-sized or properly cleaned, which means the old wood flue behind the unit still holds heavy creosote and soot pockets. We pull the insert when needed, sweep what’s actually back there, and tell you if the flue is undersized for the gas venting.
- Warped baffles and cracked refractory panels. Homes near the Des Plaines River deal with dampness that accelerates wear on Gelco fireboxes. Units that have seen mixed wood and gas use over decades show warping and cracked refractory panels more often here than in drier neighboring towns. We inspect those components during every cleaning and report what we see.
- Seized damper and venting linkage. On older Gelco units, the damper linkage corrodes or misaligns, letting flue gases and moisture attack the smoke chamber and crown above. We free up what’s repairable and replace the OEM linkage where it’s gone too far, so the unit vents properly and the chimney structure stops taking on moisture.
- Undersized flues from original open-fireplace designs. Many Gelco inserts in Des Plaines were installed into chimneys whose original clay tiles were sized for an open wood fire, not a later insert. That puts extra strain on the venting and accelerates creosote accumulation in the flue behind the unit. We flag this during cleaning and walk you through your options, which may include relining with a DuraFlex flexible liner system to match the insert.
Gelco Service in Des Plaines: What Local Conditions Mean for Your Equipment
Des Plaines sits directly under O’Hare’s flight path and along the Des Plaines River corridor, and its housing stock tells a specific story: a large share of the city’s homes were built for returning GIs in the 1950s and 1960s. Those brick and frame ranches and split-levels, especially in the 60016 and 60018 neighborhoods, still run their original clay-tile flues and masonry fireplaces. In many of them, a Gelco insert was added later, usually in the 1990s, without any re-sizing of the flue. The result is a persistent local pattern we see on calls near downtown and off the river side: an insert that functions fine at the face but vents into a flue that’s undersized, uncleaned, and cracking at the tile joints. The humid summers and river-adjacent dampness encourage creosote to cling inside those old flues, while cold snaps crack the clay tiles a little more each year. When we clean a Gelco insert in Des Plaines, we’re never just brushing out the firebox. We’re checking what’s behind the unit and inside the flue, because this city’s chimneys tell you more about the house than the fireplace face ever will. That’s why our Level 2 inspections are a routine part of the conversation here, not an upsell.
Gelco Models & Products We Service in Des Plaines
We service the full range of Gelco residential equipment you’re likely to find in Gelco service in Mount Prospect and Des Plaines homes: Gelco wood-burning fireplace inserts, Gelco factory-built (zero-clearance) fireplace units, Gelco gas fireplace inserts, and Gelco direct-vent and B-vent gas fireplace models. The factory-built zero-clearance units show up in the newer infill construction and condo conversions near the Metra downtown, while the older ranches and split-levels in 60016 and 60018 typically house wood or gas inserts set into original masonry chimneys. Every cleaning includes a visual inspection of the firebox, baffle, refractory panels, damper linkage, and venting path. When we find a component that needs replacing, we start with OEM Gelco parts where they’re still available, then move to quality aftermarket for discontinued pieces. We carry common Gelco-compatible cleaning rods, brushes, and inspection tools on the truck, which keeps turnaround in Des Plaines quick without sacrificing thoroughness.

AfterGelco Service Pricing in Des Plaines
Gelco chimney cleaning in Des Plaines typically runs between $180 and $340, depending on the unit type, accessibility, and whether we’re pulling an insert to inspect the flue behind it. A Level 2 inspection, which we recommend whenever we’re working on a 60-year-old chimney or a unit that’s been converted, adds $150 to $350. If we find cracked clay tiles or an undersized flue, a reline with a DuraFlex flexible liner system typically falls between $2,500 and $4,500, though many Des Plaines homes qualify for a HeatShield resurfacing instead, which runs $1,500 to $3,000 and avoids a full teardown. Nothing gets recommended without camera evidence you can see yourself. Call (844) 660-6510 for an exact quote. Estimates are free.

FAQs – Gelco Chimney Cleaning in Des Plaines
Yes, and this is one of the most common issues we find in Des Plaines’ 1950s-60s ranches. When a gas insert was installed into a chimney originally built for an open wood fire, the flue behind the unit often kept its old creosote and soot lining. Gas inserts vent differently than open fires, but the old deposits inside the flue don’t just disappear, and in a river-adjacent climate like Des Plaines, humidity makes them cling and harden. We pull the insert, sweep what’s actually back there, and run a camera inspection to check the tile condition. If you’re not sure when the flue behind your Gelco unit was last cleaned, call (844) 660-6510 and we’ll tell you what to expect before we start.
Yes, that’s exactly what a Level 2 inspection is for. We run a camera through the flue after sweeping your Gelco fireplace, and the footage shows us whether the clay tiles are cracked at the joints, spalling from moisture, or both. In Des Plaines, freeze-thaw cracking along tile joints is common enough that we see it on a regular basis in homes in 60016 and 60018. If the cracks are superficial and the flue is still structurally sound, we’ll tell you plainly that it can wait. If they’re allowing flue gases or moisture into the surrounding masonry, we’ll recommend a reline with a DuraFlex liner or a HeatShield resurfacing, depending on the condition. You see the camera footage before we make any recommendation. For an honest assessment after your next sweep, call (844) 660-6510.
Usually it is. A seized damper on an older Gelco insert in Des Plaines is typically caused by corrosion or misaligned linkage, which isn’t surprising given the humidity near the river and the temperature swings this area sees. We start by freeing the mechanism and lubricating the linkage, then test the full range of movement. If the OEM linkage has worn past the point of safe operation, we replace it with a new component rather than forcing it. The repair is usually done the same visit as the cleaning. Tell me what you’re seeing, and I’ll tell you what it actually means. Call (844) 660-6510 and describe the symptom, and we’ll give you an honest read before we even schedule.
Not necessarily, and we’d rather you find out before your first fire of the season. A factory-built Gelco fireplace can look completely fine from the front while the venting behind it is packed with creosote or soot, especially in Des Plaines homes where the unit has run for years without service. The firebox itself may have warped baffles or cracked refractory panels that you can’t see without pulling the face off. If the unit has been sitting for a season or more, we recommend a cleaning and Level 2 inspection before you light it. Skip the guesswork and call (844) 660-6510 to schedule before burning season.
Yes, we service Gelco gas and wood inserts in the condo buildings and converted spaces near the Metra downtown and throughout 60018, as well as the rest of Des Plaines. Condo and conversion jobs sometimes need building access coordination or fire marshal inspection scheduling, which we handle as part of the service. The venting challenges in those buildings often differ from the single-family ranches, but the Gelco equipment inside is the same, and our approach doesn’t change. We clean, inspect, and report with the same camera evidence and plain language. Call (844) 660-6510 and tell us the building type, and we’ll walk you through how the visit works.
