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 Addison, IL | Duke Chimney Sweep
We’re an independent Gelco service provider in Addison, and the short version is this: we sweep, inspect, and repair both Gelco prefab fireplaces in the 1980s-90s subdivisions and Gelco inserts retrofitted into older bungalow masonry. What makes our work here different is knowing which failure mode applies to which block. An air-cooled chase off IL-83 ages differently than a short exterior masonry chimney near the village center, and we diagnose accordingly. Call (844) 660-6510 for a free estimate on Gelco chimney cleaning anywhere in Addison’s 60101 zip code.
Why Addison Residents Choose Us for Gelco Service
Gelco factory-built systems are common across Addison, but most of our customers don’t realize their fireplace is a Gelco until we open it up. That’s fine. We know these units by their internal layout: the H Series wood-burning fireboxes, the air-cooled prefab chimney sections, the direct-vent gas inserts that show up in rental units near the Industrial Park. Rob Szymanowski grew up in Wheeling and spent years working chimneys across Cook and Lake counties. His crew knows what a Gelco unit looks like after fifteen Addison winters. We’re not authorized by Gelco, and we don’t pretend to be. We’re independent, which means we diagnose what’s actually in front of us instead of defaulting to a replacement pitch.
Our parts approach matches that. We source OEM Gelco-compatible refractory panels, caps, and dampers when the original component is still available. When it’s discontinued, we use quality aftermarket equivalents and tell you that’s what we’re doing. No mystery parts. Gelco sales & service work at our level means understanding the supply chain, not just owning a brush.

Common Gelco Chimney Cleaning Problems We Solve in Addison
Here’s what we actually find when we open Gelco systems in Addison homes:
- Cracked refractory panels. Air-cooled Gelco prefabs in 1980s-90s two-story subdivisions run hot through Chicagoland winters. Years of that thermal cycling crack the refractory brick, and heat escapes past the firebox wall. We see this constantly on streets off IL-83.
- Corroded termination caps. Gelco caps and spark arrestors take the full brunt of Addison’s snow and freeze-thaw cycles. They corrode at the top plate, loosen, and let rain and ice melt down the chase. The water reaches the damper, then the firebox.
- Sagging direct-vent sections. Gelco gas inserts in Addison rental units often have vent sections that were never properly secured, or have separated over time. A standard visual check won’t catch it. A Level 2 camera inspection will.
- Glazed creosote. Some Gelco fireboxes we open have warped grates and deteriorated refractory brick that create the exact conditions for glazed creosote, which a standard sweeping won’t fully remove. It’s a hard, shiny coating that needs mechanical removal.
- Draft problems in bungalow retrofits. Older Addison bungalows with short exterior masonry chimneys sometimes get a Gelco insert installed without anyone addressing the underlying draft and flue height problem. Then the insert gets blamed for smoking that was already there.
Gelco Service in Addison: What Local Conditions Mean for Your Equipment
Addison’s split housing stock creates two very different Gelco service profiles, and the side of town you live on determines which one applies to you—similar to how we see Gelco in Wood Dale. The two-story subdivisions from the 1980s-90s, dense around the I-355 and IL-83 corridors, dominate our Gelco prefab cleaning calls. These are air-cooled factory-built systems with their own specific failure patterns: cracked refractory panels, corroded caps, and chase leaks. The older brick ranches and bungalows near the village center are a different job entirely. Many of those have short exterior masonry chimneys that draft poorly in Addison’s flat, open DuPage County terrain, especially when winter wind hits. When a Gelco insert goes into one of those bungalows, the insert inherits whatever draft problem the original fireplace had. Tell me what you’re seeing, and we’ll tell you what it actually means. That’s the difference between sweeping a flue and actually solving the problem.
Gelco Models & Products We Service in Addison
We work on the Gelco units actually installed in Addison homes:
- Gelco H Series factory-built wood-burning fireplaces
- Gelco air-cooled prefab chimney systems with termination caps
- Gelco gas fireplace inserts and direct-vent units
- Gelco multi-flue cap assemblies on two-story subdivision chases
When a part needs replacing, we check original availability first. Gelco-compatible OEM parts come from the same specifications the manufacturer used. For discontinued components, we substitute quality aftermarket equivalents and document the choice. We stock common cap sizes, refractory panel templates, and damper assemblies for faster Addison turnaround. If your unit’s structure is sound, we repair it, just as we do for Gelco repair in Bensenville. If the firebox or chase is past safe repair, we’ll tell you that too, with photo evidence.

AfterGelco Service Pricing in Addison
Gelco chimney cleaning in Addison typically runs $160 to $300 for a standard sweep on a factory-built unit. A Level 2 camera inspection with the report adds another $125 to $200. Cap replacements vary widely: simple single-flue caps start around $60 to $150 for the component plus labor, while multi-flue assemblies and custom chase caps run higher. Refractory panel replacement is quoted case by case because panel availability differs by model. What drives the cost is the condition of the unit and whether parts are still manufactured. Our estimates are free, and we’ll walk you through the quote before any work is scheduled. Call (844) 660-6510 for an exact number on your Gelco system.

FAQs – Gelco Chimney Cleaning in Addison
Yes, if the lease renewal requires documented inspection or the landlord is asking about the fireplace’s condition. A Level 2 camera inspection gives you a dated report with photos showing the flue interior, damper, refractory panels, and cap condition. That’s the documentation landlords in Addison’s rental clusters near the Industrial Park typically want. Call (844) 660-6510 and we’ll schedule it before your renewal date.
Once a year if you burn regularly from November through March. Addison’s winters run cold and long, and even modest seasonal use builds creosote inside the air-cooled flue sections. If you only burn occasionally, every two years may suffice, but we recommend at least an inspection each fall. The cost of a sweep is less than the cost of a chase leak.
Because the top plate expands and contracts through Addison’s freeze-thaw cycles, and the screws or brackets holding the cap corrode from road salt in the air and snow sitting on the chase. Once the cap loosens, rain and ice enter the chase and start reaching the damper and firebox. We replace the cap, reseal the top plate, and use stainless fasteners so it holds. Call (844) 660-6510 for an inspection.
In most cases, yes. If the firebox structure is still sound, we replace the cracked refractory panel with an OEM Gelco-compatible panel or a quality aftermarket equivalent for discontinued models. Full fireplace replacement is only warranted when the firebox itself is compromised, a standard we apply equally to Gelco repair in Glendale Heights. We’ll show you the camera footage so you can see the actual condition before deciding.
It depends on why the chimney is smoking. If the flue is too short or drafts poorly in Addison’s flat-terrain winter winds, an insert changes the appliance but not the chimney. Sometimes the fix is extending the flue or addressing the cap and damper. We’ll inspect the whole system and tell you whether an insert is the right solution or whether the draft problem needs to be solved first.
