Gelco Chimney Repair Nationwide

Gelco Chimney Repair in Evanston: What to Know First

We provide independent Gelco chimney repair in Evanston, IL, with most jobs quoted in writing within 24 hours and completed within a week of booking. A typical Gelco mortar repointing or spalling brick repair runs $850-$2,400 depending on stack height and access, and we never start work without a written price, scope, and warranty on the table. This page is for Evanston homeowners who own a Gelco chimney cap, Gelco liner system, or Gelco-mounted appliance and need repair work done by a technician who knows the product line, not a general mason who’ll figure it out on site.

How Gelco Products Fail - and How We Fix Them

• Gelco Model C chimney caps - lid separation at the weld seam. The Model C’s stamped-steel lid is spot-welded to the skirt, and after 8-12 winters of Evanston’s freeze-thaw cycling (we see this especially on homes within a mile of the lakefront), that seam cracks and lets water run straight down the flue. We remove the cap, assess the flue for water damage, and either re-weld and re-coat the existing lid or source a replacement through Haven’s buying network if the metal’s too thin. We always check the mesh screen for corrosion while it’s off; a separated lid usually means the screen is close behind.
• Gelco pre-fab chase covers - corner pooling and rust-through. Gelco’s galvanized chase covers are common on 1990s-2010s construction in Evanston’s northwest neighborhoods, and the factory corners are flat-seamed. Snow sits in those corners, melts slowly, and the galvanizing fails from the inside out. We replace with a custom-fabricated chase cover in copper or stainless, pitched to shed water, with cross-breaks welded in. The Gelco original was a mass-produced fit; ours is measured to your chase.
• Gelco stainless flex liners - seam separation at the collar. On Gelco flex liners installed in the 2000s, the collar-to-liner seam can work loose where it meets the appliance adapter, especially if the original installer didn’t support the liner properly. We camera-scan to locate the separation, then either re-terminate with a new Gelco-compatible collar or transition to a DuraFlex or HeatShield component if Gelco’s current collar geometry doesn’t match the existing liner diameter. We document the before-and-after with photos per Haven Standard Clause 4.
• Gelco cast-in-place crown coatings - spider cracking and spalling. Gelco’s crown repair product is a cementitious coating, and in Evanston it tends to crack where the crown overhangs the brick by more than two inches. Water gets behind the coating, freezes, and pushes it off in sheets. We grind off the failed coating, assess the structural crown, and either re-pour with proper expansion joints or apply a HeatShield CrownCoat system if the substrate is sound. The fix depends on what the camera and hammer test show, not what we hope.
• Gelco top-sealing dampers - cable fraying and frame rust. The Gelco Lyemance and Lock-Top damper lines use a stainless cable that runs down the flue to a handle assembly. In Evanston’s older masonry stacks, especially the tall Victorian flues near the lakefront historic district, that cable rubs on mortar protrusions and frays at the 12-15 foot mark. We replace the cable, smooth the flue interior if needed, and lubricate the frame pivot. If the frame itself is rusted solid, we quote a new damper assembly in writing before ordering parts.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, checks availability, and books a Level 2 camera inspection. You’ll get a text when your technician is en route.
2. 2
   NFPA 211 Level 2 inspection on arrival. We run the camera down the flue, photograph the Gelco component and surrounding masonry, and take moisture readings where water damage is suspected. Corrine Halstead and her crew have been inspecting stacks across Evanston for several years, including the older masonry near the lakefront historic district.
3. 3
   Written diagnosis and price. We show you the camera footage first and the invoice second. Nothing gets approved without both on the table. The written scope names OEM Gelco parts, quality aftermarket alternatives, or multi-brand solutions from DuraFlex or HeatShield, with the trade-off explained for each.
4. 4
   Repair with documented photo record. We perform the work, photograph completed joints, welds, or installations, and note any conditions we found that weren’t visible on the initial scan.
5. 5
   Final test and walkthrough. For dampers, we cycle the assembly and verify seal. For liners, we video the full length post-repair. For masonry, we mist-test if conditions allow.
6. 6
   Written warranty and 365-Day Done Right Promise. You leave with photos, a written scope, and a warranty document. If it’s not done right, we make it right.
