This page is for Elmhurst homeowners who installed a Gelco chimney cap, Gelco top-sealing damper, or Gelco liner system between 2015 and 2023 and need cleaning, inspection, or maintenance from a technician who knows the product line. We are not affiliated with or authorized by Gelco; we are an independent service provider with sixteen years of documented Gelco fieldwork across DuPage County.

How Gelco Products Fail - and How We Fix Them

• Gelco Model C chimney caps: mesh screen corrosion from freeze-thaw cycling. The Model C’s 18/8 stainless mesh is rated for general use, but Elmhurst’s 35-40 annual freeze-thaw days with road salt aerosol from North Avenue and York Road traffic accelerate pitting at the weld points. We see this most often on homes south of the Metra tracks where cap orientation catches prevailing westerlies. Our fix: remove the cap, document mesh integrity with the camera, replace with Gelco OEM mesh or a heavier 304-grade aftermarket equivalent sourced through our Haven buying network, and reseal the base flange.
• Gelco Lyemance top-sealing dampers: silicone gasket hardening and incomplete seal. The Lyemance uses a silicone rubber gasket against a cast-aluminum throat plate. After 6-10 Elmhurst winters, the gasket loses pliability and the damper seats with a 1/8-inch gap, enough to pull conditioned air up the flue year-round. During sweep appointments we test the seal with a smoke pencil and measure the gap. Replacement gaskets are available; if the throat plate is warped from over-tightening, we document it and quote a Lyemance rebuild or a Lock-Top conversion.
• Gelco stainless flexible liners: creosote bridging at corrugated valleys. Gelco’s corrugated flex liner increases surface area 15-20% over smooth-wall, which traps Class II and III creosote in the valleys, especially with improperly seasoned oak or elm, the two most common firewood species we see delivered to Elmhurst homes. Our rotary cleaning with polypropylene whips reaches into those corrugations; for heavy glaze we apply a Poultice Creosote Remover and return for a second pass, documented with before-and-after camera footage.
• Gelco chase covers: corner seam separation on prefab chimneys. The Gelco chase cover is a galvanized or stainless pan with cross-breaks and drip edges. On Elmhurst’s 1990s-era prefab installations, especially in the York Woods and Wild Meadows areas, we find the factory corners opening after 12-15 years of thermal expansion. Water stains on the firebox ceiling are the symptom. We pull the cover, show the owner the seam separation on camera, and fabricate a replacement with soldered corners or a single-piece break, depending on chase dimensions.
• Gelco wind-directional exhaust caps: flap hinge seizure. The wind-directional cap uses a hinged flap that opens under draft pressure and closes when the fire dies. The hinge pin is unsealed 410 stainless; Elmhurst’s summer humidity and winter freeze cycles cause corrosion that locks the flap open or shut. A stuck-open flap admits rain and wildlife; stuck-shut, it blocks draft and smokes out the room. We disassemble the hinge, clean and lubricate with high-temp graphite, or replace the cap assembly if the pin is scored.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Schedule and confirm. You call (708) 498-3199, a live person answers, and we book a two-hour arrival window. You receive a text when your technician is en route with a photo and name.
2. 2
   Arrival and site review. The technician lays protective runners, reviews your Gelco product model from prior documentation or on-site identification, and confirms the scope before touching equipment. Written price, written scope, written warranty - Haven Standard Clause 1.
3. 3
   Camera-scan inspection (NFPA 211 Level 2). We run a 360-degree camera from the firebox to the cap, recording flue liner condition, creosote class and thickness, and any Gelco-specific wear points. The camera doesn’t editorialize. Neither do I. You watch the live feed or receive the recording link.
4. 4
   Cleaning and maintenance. Rotary sweeping with brush selection matched to your Gelco liner type (corrugated flex, smooth-wall, or rigid). Damper gasket test, cap mesh inspection, chase cover seam check. Parts decisions are discussed: Gelco OEM when available, quality aftermarket from our DuraFlex, HeatShield, or Olympia Chimney supply when equivalent or superior.
5. 5
   Documentation and closeout. Photos, camera footage, and a written condition report are uploaded to your record. The technician reviews findings, delivers the final price if additional work is needed, and stamps the 365-Day Done Right Promise on every document. Cleanup is complete; nothing is recommended without camera evidence you can see for yourself.

Why Elmhurst Homeowners Call Level Two Chimney Elmhurst for Gelco Work

We’ve cleaned and inspected more than 38,000 chimneys since 2009, every one with a written price first and a photo record after. Corrine Halstead built this crew on the principle that documentation settles arguments before they start. When we find a Gelco liner with creosote bridging or a chase cover with corner separation, we show you the footage, name the part, and give you the price. The 365-Day Done Right Promise means if the gasket we replaced leaks or the mesh we installed pulls at the weld, we return and make it right. Our materials come from Gelco, DuraFlex, HeatShield, and Olympia Chimney through the Haven buying network, so we’re not locked into a single manufacturer’s inventory when a better-fit part exists. Background-checked, uniformed technicians. License on the page. Text when we’re on the way. That’s the standard.
