Gelco Chimney Cleaning in Arlington Heights, IL | Duke Chimney Sweep
We provide independent Gelco chimney cleaning and inspection across Arlington Heights, including all three ZIP codes: 60004, 60005, and 60006. The one thing that makes our Gelco work here different: we know that most Arlington Heights chimneys built between 1950 and 1975 house a shared stack serving both a fireplace and a vented furnace. A routine Gelco sweep in this town is rarely just a sweep. It’s an inspection of multiple flue tiles, a check on the Gelco damper assembly, and a straight conversation about what actually needs fixing before the first hard freeze. Call (844) 660-6510 to book a Gelco service visit.
We work on Gelco-lined fireplaces and Gelco chimney components throughout Chimney Sweep – Arlington Heights every week. These systems age in a particular way here. That’s what this page is about: what we see in your chimney, why it happens in this town, and what’s actually worth fixing.
Why Arlington Heights Residents Choose Us for Gelco Service
Duke Chimney Sweep has worked on Gelco-equipped fireplaces across Arlington Heights’ older housing stock for years. We know how Gelco flexible liners, caps, and damper assemblies behave after two or three decades of Chicagoland freeze-thaw cycling. That familiarity matters more than a manufacturer logo on a truck. We are an independent service crew, not a Gelco-authorized outlet. Our Gelco sales & service work is grounded in what we actually find in the flue, not a script from a brand rep.
Rob Szymanowski, our owner, spent years working chimneys and dryer vents across Cook and Lake counties before building Duke Chimney Sweep. He learned the mechanical and safety fundamentals through the HVAC and building systems program at Harper College in Gelco repair in Palatine, ten minutes from Arlington Heights. When we fit a Gelco-compatible liner or replace a Gelco damper, we’re working with specification-grade materials from DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. The same brands chimney engineers specify. Not hardware-store substitutes.
We’re not the cheapest bid in Gelco repair in Rolling Meadows or Arlington Heights, and we don’t try to be. We’re the crew that tells you plainly when a Gelco component can be repaired and when a reline or rebuild is the better spend. Tell me what you’re seeing, and I’ll tell you what it actually means.

Common Gelco Chimney Cleaning Problems We Solve in Arlington Heights
- Separated or crushed Gelco flexible liners. Many mid-century ranches and split-levels in the 60004 and 60005 ZIP codes got Gelco stainless liners installed in the 1980s or early 1990s. After 30-plus winters of hard freezes, the corrugated stainless flex can separate at joints or crush inward, especially where the liner bends at a smoke shelf. During a sweep, we check for this. If the liner is sound, we clean it. If it’s compromised, we tell you before recommending a DuraFlex reline.
- Cracked or rusted Gelco caps and top-sealing assemblies. Arlington Heights sits in a cold continental climate with repeated freeze-thaw cycles from late fall through early spring. Gelco caps from the 1970s and 1980s develop hairline cracks in the housing that widen over time. Spring rain and summer humidity then seep into an uncapped or poorly capped flue. We see the damage downstream: spalling brick, failed mortar crowns, and rust-stained damper housings.
- Seized Gelco damper assemblies. A rusted damper that’s stuck open in a 1950s brick colonial isn’t an inconvenience. It’s a heat leak. In January, a wide-open damper moves conditioned air up the flue and cold air down into the living room. We free, repair, or replace Gelco dampers depending on the condition of the linkage and the damper plate.
- Cracked Gelco flue tile sections at shared-stack mortar joints. In older Arlington Heights neighborhoods near downtown, many homes share a chimney stack between the fireplace and a vented furnace. That’s two flues running through one masonry structure. When one clay tile cracks at a mortar joint, we often find the adjacent Gelco liner or damper showing moisture damage too. Sweeping one flue without inspecting the other misses the actual problem.
- Creosote buildup in Gelco liners serving wood-burning fireplaces. Even a properly installed Gelco liner accumulates creosote. Arlington Heights’ cold winters push homeowners toward longer burn seasons, which means heavier glazing and more fire risk. Our sweep includes full creosote removal from the Gelco liner, with photo documentation so you can see the condition before and after.
Gelco Service in Arlington Heights: What Local Conditions Mean for Your Equipment
Here’s the piece most generic chimney pages won’t tell you: in the older neighborhoods around downtown Arlington Heights and the 60004/60005 split, it’s common to find chimney stacks shared between adjacent fireplaces or vented furnaces. A brick colonial near the Metra station doesn’t have one flue. It has two, sometimes three, running through the same masonry. That changes the math on a Gelco cleaning. Sweeping the fireplace flue is straightforward. But if the adjacent furnace flue tile has cracked at the joint, the Gelco damper below it can rust out within a season. We’ve pulled failed tile sections and documented shared-stack conditions with photos more times than we can count. In this town, a “simple” Gelco sweep becomes a multi-flue inspection before the first hard freeze. That’s not upselling. That’s knowing what these older Arlington Heights stacks are hiding.
On a brick colonial near downtown Arlington Heights, our tech swept a Gelco-lined fireplace flue and found the adjacent furnace flue tile cracked at the joint, with rust staining the Gelco damper below. We pulled the failed tile section, documented the shared-stack condition with photos, and scheduled crown repair and a reline recommendation before the freeze set in.
Gelco Models & Products We Service in Arlington Heights
We service the Gelco product lines most common in Arlington Heights homes. That includes Gelco stainless steel flexible chimney liner kits, Gelco terra-cotta flue tile replacement sections, Gelco top-sealing and multi-flue caps, and Gelco fireplace dampers and damper assemblies. These are the components we see in 1950s ranches, 1960s split-levels, and two-story brick colonials across the 60004, 60005, and 60006 ZIP codes.
Our parts approach is repair-first. When a Gelco liner is sound and only the cap needs attention, we fit a Gelco-compatible OEM-spec cap and extend the system’s life. When a Gelco damper assembly is discontinued or priced beyond reason, we switch to quality aftermarket stainless or cast components. We tell you which is which. No guessing.
We also perform Level 2 inspections, creosote removal, and crown repair as standalone Gelco services. If your Gelco crown is cracked but the chimney structure is otherwise solid, HeatShield resurfacing can restore the flue without a full teardown. That’s a meaningful cost difference in Arlington Heights, where full chimney rebuilds run high on 70-year-old stacks.

FAQs – Gelco Chimney Cleaning in Arlington Heights
Any Gelco liner that’s been in service since the 1990s should get a Level 2 camera inspection before we run a brush through it. Freeze-thaw cycling in Arlington Heights can separate flex liner joints or crush corrugation without showing symptoms from the hearth. The inspection confirms the liner is sound enough to sweep safely. If it’s compromised, sweeping alone won’t fix it. Call (844) 660-6510 and we’ll schedule the sweep and inspection together.
That’s almost always rust on the damper hinge or linkage, caused by moisture migrating down the flue during freeze-thaw cycles. Split-levels in the 60004 ZIP often have exterior chimney walls on three sides, which makes condensation worse. We free the linkage if it’s salvageable, or replace the Gelco damper assembly with a stainless-compatible part if the original has rusted through.
Yes. Shared stacks are standard in the older homes near downtown Arlington Heights, and we inspect every flue in the stack, not just the one attached to the fireplace. That’s how we catch cracked furnace flue tiles before they compromise the Gelco components below. We’ll document each flue with photos and show you exactly what we found.
Often, yes. If the crown wash has cracked but the underlying masonry is structurally sound, HeatShield resurfacing can seal and protect the flue without a full crown rebuild. We restore before we replace, but we’ll also tell you straight when a repair won’t hold and a rebuild is the honest recommendation.
A properly fitted Gelco cap will stop most of the water that would otherwise enter the flue, which is the biggest driver of cracked tiles in Arlington Heights’ freeze-thaw climate. But if tiles have already cracked, a cap alone won’t fix them. We’ll inspect, cap if it’s the right first step, and tell you what the tiles actually need. Call (844) 660-6510 for a free estimate.
