A Level company - serving Elmhurst, IL

Gelco Chimney Liner & Rebuild Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

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 Liner & Rebuild in Elmhurst: What to Know First

We provide independent Gelco chimney liner and rebuild service in Elmhurst, with most liner replacements completed in one day and full rebuilds typically scheduled within a week. Every job starts with a camera-scan inspection and a written price before any work begins - no exceptions. If you own a Gelco liner system and you’re seeing rust flakes in the firebox, draft problems, or a sudden creosote buildup that doesn’t match your burning habits, call (708) 498-3199. Corrine Halstead and our crew have worked Gelco systems across Elmhurst, from the older bungalows near York Woods to the brick colonials along the Prairie Path corridor, and we keep both OEM and quality aftermarket Gelco-compatible parts in our buying network.

How Gelco Products Fail - and How We Fix Them

  • Gelco UltraPro flexible liners in Elmhurst’s freeze-thaw climate often develop circumferential cracks at the first joint above the smoke chamber. The 316Ti alloy handles the flue gases fine, but the seam weld sees thermal shock every time a cold chimney meets a hot fire. We cut back to sound metal, install a Gelco-compatible transition section, and pressure-test before we leave.
  • Gelco stainless rigid pipe systems (common in Elmhurst homes with straight, tall flues) suffer offset joint separation after 10-15 years. The locking bands corrode from the outside in, especially where attic insulation traps moisture against the outer wall. We replace with matched-band assemblies or transition to a DuraFlex equivalent when Gelco lead times stretch past two weeks.
  • Gelco smooth-wall liners delaminate at the seam weld when installed with an oversize insulation blanket. The gap lets condensation pool, and the hydrochloric acid from coal soot or modern compressed logs eats the seam from the inside. We pull the liner, verify the flue dimension with a laser measure, and reinstall with the correct pack - or switch to HeatShield cerfractory resurfacing if the flue is structurally sound.
  • Gelco top plates and termination caps on Elmhurst homes with shallow-pitch roofs collect ice in the collar gap. The freeze-thaw pops the seal, and water runs down the outside of the liner, rusting the top course of flue tiles underneath. We replace the cap, seal with high-temp silicone rated to 600°F, and document the flue tile condition with photos - Clause 4 of the Haven Standard.
  • Gelco oval-to-round adapters in fireplace insert installations work harden at the crimp points after repeated heating cycles. The metal thins, the creosote finds the gap, and you get a Class III glazed deposit exactly where you can’t reach it with a standard brush. We pull the insert, replace the adapter, and run a rotary poly chain to bare metal before reassembly.

Our Gelco Chimney Liner & Rebuild Process

Our Gelco Chimney Liner & Rebuild Process
  1. 1
    Camera-scan inspection. We drop a 360° camera from the top and scan up from the firebox. The footage goes to a tablet you can watch in real time. Corrine Halstead reviews every scan before any price is discussed - “The camera doesn’t editorialize. Neither do I.”
  2. 2
    Written scope and price. We deliver a single-page document: what we found, what it costs, what parts we’ll use, and what the warranty covers. Haven Standard Clause 1 - have it in writing. No verbal estimates, no “we’ll see when we get into it.”
  3. 3
    Parts decision. If your job specifies Gelco OEM, we source through our Haven buying network. If Gelco backorders the part (their 6-inch smooth-wall has run 3-4 weeks at times), we quote a DuraFlex or Olympia Chimney equivalent with identical alloy specs and warranty terms. You choose before we order.
  4. 4
    Installation or rebuild. Liner jobs: we pull the old, prep the flue, install the new with proper insulation pack, and lock the termination. Rebuilds: we work course by course, matching existing brick where possible, and install a new crown with proper drip edge and expansion joint.
  5. 5
    Pressure test or smoke test. Liners get a NFPA 211-compliant pressure test at 1.5 times working draft. Rebuilds get a smoke pellet test to verify no leakage at the new-to-old interface. We record both on video.
  6. 6
    Photo record and warranty. You get a USB drive or cloud link with inspection photos, test footage, and your written warranty. We keep a duplicate on file. The 365-Day Done Right Promise applies from day one.
