Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Why Elmhurst Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco repair in Elmhurst, including chimney cleaning and inspection, with camera-scan documentation on every visit and a written price before any work starts. Our technicians have serviced Gelco G Series and H Series factory-built fireplaces across DuPage County for over a decade, and we stock the OEM dampers, firebox panels, and multi-flue caps these units actually need. We’re not affiliated with or authorized by Gelco; we’re an independent service provider who knows these systems from fieldwork, not from a dealer manual. Call (708) 498-3199 for a free estimate.
Why Trust Level Two Chimney Elmhurst for Your Gelco Chimney Cleaning?
Corrine Halstead, our owner, learned the trade at BOCES Vocational Technical Center in Queens and has spent more than two decades inspecting chimneys. She built this crew specifically to work the older housing stock of Elmhurst, where Gelco factory-built fireplaces were installed in bungalows and brick Colonials from the 1970s through the 1990s. The camera doesn’t editorialize. Neither do I. That phrase ended up on our vans because it’s how Corrine runs every job: pull the camera first, show the homeowner what the flue actually looks like, then discuss price.
Our technicians carry OEM Gelco dampers, refractory panels, and gaskets on every truck. We don’t guess at clearances on factory-built units; we measure them against the original Gelco specifications. When a Gelco part has been discontinued, we source UL-listed aftermarket equivalents rated for the same temperature and clearance, and we document the substitution in writing. Every Gelco job we perform includes a Level 2 camera inspection under NFPA 211, a written scope, a written price, and a documented photo record - Clause 4 of the Haven Standard, which we’ve followed since 2009. The 365-Day Done Right Promise applies to every Gelco repair and installation we complete, including Gelco in Westchester.
Common Gelco Chimney Cleaning Problems We Fix in Elmhurst

- Cracked or spalled refractory firebox panels in Gelco G Series units. After 15 or more seasons of burn cycles, the ceramic panels lining the firebox develop hairline fractures or surface spalling - flaking caused by repeated thermal shock. In Elmhurst’s 1920s-1940s homes, these fireplaces were often retrofitted into existing chimney structures with limited clearance to combustibles, which concentrates heat stress on the panels. We replace with OEM Gelco panels when available, or with UL-listed equivalents that match the original thickness and insulation value.
- Rusted or seized Gelco damper assemblies. The cast iron or steel damper blades in Gelco prefab fireplaces corrode when condensation accumulates in the flue during shoulder seasons. Once the damper won’t close fully, heated air escapes continuously and the fireplace becomes a net heat loser. We stock OEM Gelco dampers for common 36-inch and 42-inch units and can replace the assembly without disturbing the firebox surround.
- Deteriorated Gelco multi-flue caps with corroded spark screens. The mesh spark arrestor on Gelco multi-flue caps traps moisture against the metal frame, particularly in Elmhurst where northwest winds drive rain directly into exposed chimney crowns. When the screen rusts through, squirrels and raccoons enter, and water pools on the smoke shelf below. We install replacement Gelco caps or equivalent stainless-steel assemblies with proper overhang and screen tension.
- Shaling creosote accumulation in Gelco prefab flues. Factory-built fireplaces run cooler than masonry systems, which means incomplete combustion and heavier creosote deposits. The creosote flakes off in thin, brittle sheets - “shaling” - and can block the narrow flue collar on Gelco units. We sweep with poly brushes sized to the Gelco flue diameter and inspect with a camera to confirm the flue is clear to the termination cap.
- Draft failure in Gelco H Series high-efficiency units. The H Series is designed for tighter homes with sealed combustion, but in Elmhurst’s older stock with original windows and minimal weatherstripping, the fireplace can be too tight for the available makeup air. We test draft pressure with a manometer, check the Gelco air intake for obstruction, and advise on combustion air solutions if the unit is starved.

AfterGelco Parts & Our Repair-vs-Replace Approach
We use OEM Gelco dampers, firebox panels, and caps whenever they’re available because fit and clearance are critical on factory-built units; a quarter-inch tolerance error can create a combustion hazard. When Gelco has discontinued a part - common for G Series units manufactured before 2005 - we source UL-listed aftermarket equivalents rated for the same temperature and clearance, and we note the substitution on your written invoice.
We’ll always tell you when a Gelco fireplace is at the end of its service life rather than sell a repair that won’t hold. Factory-built fireplaces have a finite lifespan, typically 20-30 years depending on use and maintenance. If the firebox wrapper is warped, the heat exchanger is cracked, or the unit has been recalled, we say so plainly and provide a written replacement estimate. No repair is booked without camera evidence you can see for yourself. Call (708) 498-3199 for a free second opinion on any written estimate you’ve already received.
Our Gelco Service Process - Step by Step

- 1
Diagnosis with camera inspection. We remove the Gelco baffle and access panel, run a chimney camera the full length of the factory-built flue, and photograph the firebox panels, damper assembly, and smoke shelf. For Elmhurst homes with original clay-tile-lined chimneys housing a Gelco insert, we inspect the surrounding flue for condensation damage from the unlined furnace flue common in these properties.
- 2
Written scope and price. Before any work begins, you receive a written price, written scope, and written warranty - Haven Standard Clause 1. If we find a cracked firebox panel or seized damper, we show you the camera footage and quote the repair. No work starts until you approve in writing.
- 3
Repair or installation with OEM or equivalent parts. We perform the sweep, replace the failed component with Gelco OEM or UL-listed equivalent, and re-seal all firebox joints with high-temp refractory caulk. For cap replacements, we verify proper screen mesh size and termination height per Gelco specifications.
- 4
Post-service testing and documentation. We run a draft test, verify damper operation, and provide a documented photo record of the completed work - Haven Standard Clause 4. Your warranty and invoice are in writing before we leave.
