We’re not affiliated with or authorized by Gelco. We’re an independent service provider who has built deep expertise on Gelco equipment through thousands of field hours across Naperville’s subdivisions, from Hobson West to White Eagle to the Riverwalk corridor. That independence matters because it means we source parts based on what your chimney actually needs, not what a manufacturer wants to sell you.

Naperville’s housing stock shapes our Gelco work in specific ways. The 1980s-1990s subdivision boom filled this city with prefabricated zero-clearance fireplaces, many topped with Gelco multi-flue caps and chase covers that are now 25-40 years old. Those caps sit through brutal DuPage County freeze-thaw cycles every winter, temperatures swinging from below 0°F through 32°F repeatedly. By April, we’re documenting the damage: corroded mesh, lifted bases, and water stains down chase walls. Meanwhile, older homes near downtown Naperville still run Gelco single-flue stainless caps on original clay-tile flues, and those present an entirely different maintenance profile. We know both.

Corrine Halstead, our owner, grew up in Queens and learned this trade at New York City College of Technology before bringing her work west to the Chicago suburbs. She and our crew have been servicing Naperville for several years now, including jobs out near the Riverwalk where older homes tend to hide the most interesting flue conditions. The camera doesn’t guess. Neither do we.

Why Trust Level Two Chimney Naperville for Your Gelco Chimney Cleaning?

We’ve freed stuck Gelco dampers, rebuilt Gelco fireboxes, and swept more Gelco flues than any other manufacturer’s in Naperville. Our independent Gelco expertise comes from thousands of hours on this exact equipment, not from any affiliation with the brand.

Our technicians arrive uniformed, background-checked, and named on your appointment text. License information is displayed on every page we publish. We don’t send anonymous crews. Under the Haven Standard, Clause 1 requires a written price, written scope, and written warranty before anyone touches your chimney. That means you’ll see exactly what your Gelco service costs, what it covers, and what we guarantee, all in writing, before we unload a ladder.

We’ve completed more than 38,000 our Chimney Cleaning & Sweep services since 2009. Every single one had a written price before work started and a documented record when finished. For Gelco systems specifically, we stock genuine replacement dampers, cap components, and crown materials whenever available, and we use equivalent high-grade stainless or cast-iron aftermarket parts when Gelco OEM supply is backordered. We source materials through Haven’s buying network, which includes DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, specifically to keep customer prices honest.

Corrine is known for showing up with a camera and leaving with written findings. No verbal estimates, no follow-up guesswork. When she’s not on a roof, she’s probably overcaffeinated and rereading the same inspection report twice before she’ll sign off on it. That temperament runs through our entire Naperville operation.

Common Gelco Chimney Cleaning Problems We Fix in Naperville

• Rusted or seized damper plates in Gelco fireboxes that prevent proper flue closure. Naperville’s humidity swings from summer highs to winter furnace-dry indoor air, and that cycling corrodes steel damper plates faster than in coastal climates. A stuck-open damper bleeds heated air 24 hours a day. A stuck-closed damper traps smoke and carbon monoxide in your living space. We inspect Gelco damper operation with a camera down the flue and replace the plate or full assembly based on what we find, not on a parts quota.
• Cracked or spalling brick at the crown-to-flue transition due to freeze-thaw cycles. This isn’t a Gelco-exclusive problem, but Gelco crown coatings are specifically formulated to bridge small cracks before water penetrates. We apply Gelco Crown Coat or equivalent where the substrate is sound, and we recommend full rebuild when the brick below has lost structural integrity. Naperville’s hard winters make this distinction critical. A coating over crumbling brick is wasted money.
• Corroded Gelco multi-flue caps where the mesh or base has deteriorated, allowing water entry and animal nesting. The 304 stainless mesh on Gelco multi-flue caps can pit through after 15-20 years of acid rain and salt-laden suburban air. Once the mesh fails, squirrels and starlings move into the chase, and their nesting material becomes a fire hazard. We stock replacement mesh panels and full cap assemblies for common Gelco multi-flue sizes, and we can fabricate custom fits for non-standard chase dimensions.
• Warped or detached Gelco top-mount damper assemblies that no longer seal, causing energy loss and smoke spillage. Naperville’s spring storms with 60+ mph gusts have shifted many a top-mount damper off its seat. The silicone gasket compresses permanently after years of heat cycling, and the plate warps slightly each time. Eventually the damper leaks even when fully closed. We test seal integrity with a smoke pencil and replace the assembly when leakage exceeds acceptable limits under NFPA 211.
• Failed refractory panels in Gelco-compatible prefab fireboxes that have exceeded their UL-listed service life. This is the Naperville-specific wave we mentioned. Homes built in Hobson West, Cress Creek, and White Eagle during the 1990s often have Heatilator, Superior, or Majestic units with Gelco caps and dampers. When the refractory panels crack or the firebox walls warp, NFPA 211 requires the fireplace be taken out of service immediately. We document the condition with photos, explain replacement options, and never pressure for a repair that won’t meet code.

Gelco Parts & Our Repair-vs-Replace Approach

We stock genuine Gelco replacement dampers, cap components, and crown materials whenever available, and use equivalent high-grade stainless or cast-iron aftermarket parts when Gelco OEM supply is backordered. Our Naperville warehouse carries common Gelco single-flue and multi-flue cap sizes, top-mount damper assemblies for 8″-13″ flues, and Crown Coat material for crack bridging up to 1/8 inch.

If a Gelco firebox or damper is too far gone, we’ll tell you straight and walk you through replacement options. No upselling on repairs that won’t hold. We’ve seen competitors patch a rusted-through damper plate with sheet metal screws and caulk, only to have the homeowner call us six months later when the patch failed. We don’t do that. Under the Haven Standard, our 365-Day Done Right Promise means if it’s not done right, we make it right. That promise is stamped on every job.

We recently serviced a Gelco top-mount damper in a 1990s Naperville two-story where the handle had snapped off and the plate was rusted open, letting cold air pour in all winter. After sweeping the flue, we replaced the damper assembly with a Gelco-compatible stainless unit and re-seated the cap that had shifted during a spring storm. The homeowner said the fireplace finally held heat instead of bleeding it.

Our Gelco Service Process - Step by Step

1. 1
   Diagnosis with camera-scan inspection. We run a chimney camera down your Gelco flue to document creosote buildup, liner condition, and damper operation. For top-mount dampers, we photograph the plate, gasket, and frame from above. For multi-flue caps, we document mesh integrity and base sealing. You see what we see. Clause 4 of the Haven Standard requires this photo record on every job.
2. 2
   Written scope and price before work. We deliver a written price, written scope, and written warranty before anyone starts. No exceptions. You’ll know exactly what Gelco parts we’re using, whether they’re OEM or equivalent aftermarket, and what the warranty covers.
3. 3
   Repair or install with documented technique. Our technicians perform the agreed Gelco service: sweep, damper replacement, cap installation, or crown repair. We photograph completed work for your record. Background-checked, uniformed crews. License number on the page. A text when we’re on the way.
4. 4
   Operational test and safety verification. We test damper operation through full open and close cycles. We verify cap stability and mesh security. For crown repairs, we check coating adhesion and coverage. We run a final camera pass to confirm flue cleanliness.
5. 5
   Warranty documentation and archive. You receive a completed Haven Standard job record with photos, scope, and warranty terms. Our archive preserves this documentation for future reference. The 365-Day Done Right Promise applies from this date.

Gelco Products We Service & Install in Naperville

We work on the full Gelco residential line: Top-Mount Multi-Flue Caps in galvanized and stainless finishes; Single-Flue Stainless Caps for standard and oversized flues; Chimney Crowns and Crown Coatings for crack repair and waterproofing; and Custom Fabricated Caps for non-standard chase dimensions or architectural matching. We stock the most common sizes for Naperville’s 1980s-2000s housing stock, including 9″×13″ and 13″×13″ multi-flue bases and 8″-12″ single-flue models. Custom fabrication typically ships within 5-7 business days through our Haven network supplier.

We Also Service These Brands

Our multi-brand capability means we don’t depend on Gelco alone. We service and install DuraFlex liner systems, HeatShield cerfractory flue resurfacing, Olympia Chimney stainless liners, and caps and hardware from Famco and Copperfield. This breadth matters because many Naperville chimneys have mixed-component histories, a Gelco cap on a HeatShield-lined flue, or a DuraFlex liner needing a new Gelco top-mount damper. We handle the full stack.

FAQs - Gelco Chimney Cleaning Service in Naperville

Is Level Two Chimney Naperville authorized by Gelco?

No. We are an independent Gelco service provider, not affiliated with or authorized by the manufacturer. Our expertise comes from thousands of field hours on Gelco equipment across Naperville, not from factory certification. We source genuine Gelco parts when available and equivalent high-grade alternatives when needed.

My Gelco top-mount damper handle snapped off-can you fix just the handle or do I need a whole new assembly?

Usually the whole assembly. The handle snaps because the damper plate has rusted in place and excessive force was applied. By the time the handle fails, the plate, hinge, and frame are typically corroded too. We inspect with a camera to confirm, but partial handle replacement alone rarely lasts. Call (331) 265-1700 and we’ll give you a written price for the full repair.

How do I know if my Gelco multi-flue cap is letting water in?

Check the chase interior after rain for dampness or rust streaks on the metal firebox wrapper. From outside, look for missing mesh sections, lifted base corners, or gaps between cap and chase top. Naperville’s freeze-thaw cycles accelerate base seal failure. We document cap integrity during every camera inspection and can show you exactly where water is entering. Call (331) 265-1700 for a free inspection.

Can you repair a cracked Gelco chimney crown without rebuilding the whole top?

Yes, if the crack is 1/8 inch or less and the brick below is sound. We apply Gelco Crown Coat or equivalent flexible coating after cleaning and priming the crack. If the brick is spalling or the crack is through to the flue liner, partial rebuild is necessary. We photograph the crown from above and below so you can see which category you’re in. Call (331) 265-1700 for a written assessment.

Do you carry Gelco OEM parts, or will you use generic replacements?

We stock genuine Gelco replacement dampers, cap components, and crown materials whenever available. When Gelco OEM is backordered, we use equivalent high-grade stainless or cast-iron aftermarket parts that meet or exceed original specifications. We tell you which we’re using before we start, and both are covered under our 365-Day Done Right Promise.

My Gelco fireplace insert smells like smoke even when the damper is open-what’s wrong?

Likely a negative pressure issue, blocked flue, or failed smoke chamber. Even with the damper open, smoke will spill into the room if the chimney can’t draft properly. We check for bird nests, heavy creosote buildup, and smoke chamber deterioration with our camera scan. In Naperville’s tight 1990s homes, kitchen exhaust fans and HVAC returns often compete for makeup air. We diagnose the actual cause and give you a written fix with price. Call (331) 265-1700.
