How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue Chimney Caps (Model M-8 through M-13 series) - The 304 stainless mesh on these caps fatigues at the weld points after seven to ten years in Kennesaw’s freeze-thaw cycle. We see this most often on homes near Kennesaw Mountain where wind exposure accelerates metal fatigue. Our fix: remove the cap, assess flue wall condition with a camera scan, then install a replacement cap with heli-arc welds and a wider overhang to shed water past the crown. We source through Haven’s buying network to keep the price honest.
• Gelco Single-Flue Caps with Leg Brackets (L- series) - The leg brackets loosen where they bear on the flue tile edge, especially after thermal cycling in a gas-insert fireplace that starts and stops frequently. This creates a gap that funnels water directly onto the smoke shelf. We replace with a Gelco cap using extended leg brackets sized to the flue, or shift to a HeatShield-compatible cap if the flue tile is too eroded for secure seating.
• Gelco Chimney Crowns (pre-formed polymer-concrete units) - These crowns crack at the corner radii when the underlayment shifts, a problem amplified by the clay-heavy soils in Kennesaw’s older neighborhoods like those off Cherokee Street. Water enters, freezes, and spalls the brick below. We remove the crown, repair the wash with a bonded polymer overlay, and reset with a new Gelco crown or a poured-in-place alternative if the chimney is out of square.
• Gelco Lyemance and Lock-Top Top-Sealing Dampers - The cast-aluminum frame corrodes where it meets the flue tile in high-moisture flues, common in Kennesaw homes where the fireplace sits unused through humid summers. The damper plate then jams open or fails to seal. We camera-inspect the frame seat, replace with a new Gelco damper if the seat is sound, or recommend a HeatShield flue resurfacing first if the tile is degraded.
• Gelco Stainless Steel Liners (pre-2016 flex liners) - Early Gelco flex used a lighter-gauge corrugated wall that ovalized during pulls in tight flues, creating low spots where creosote pools. In Kennesaw, we find this in 1980s and 1990s ranch homes with exterior chimneys that have settled slightly off-plumb. Our fix: pull a new DuraFlex or Gelco liner with proper gauge for the appliance, camera-verify the full length, and document the ovality correction.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, asks what Gelco product you have if you know it, and books a Level 2 inspection. You’ll get a text when your tech is en route.
2. 2
   Camera-scan inspection. We run a camera the full flue length, photograph the Gelco component and surrounding masonry, and record creosote class and liner condition. This is Clause 4 of the Haven Standard - no exceptions.
3. 3
   Written price and scope. Before any repair is scheduled, you receive a written price, a written scope of work, and a written warranty. We write it down before we ask you to decide anything.
4. 4
   Parts decision. We use Gelco OEM when it preserves warranty coverage or matches existing components; we use DuraFlex, HeatShield, or quality aftermarket when they perform better for the specific failure mode. We explain the choice in writing.
5. 5
   Repair and test. The work is completed by a background-checked, uniformed technician. We test draft, verify damper function, and run a final camera pass to confirm the fix.
6. 6
   Documentation and follow-up. You receive a photo record of before, during, and after, plus a stamped 365-Day Done Right Promise. If it’s not done right, we make it right.

Why Kennesaw Homeowners Call Level Two Chimney Kennesaw for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those have been in Cobb County - including the older two-story colonials near Kennesaw Mountain where Corrine Halstead and her crew regularly find surprises in the flue. Corrine completed her chimney and heating systems training at Apex Technical School in Manhattan before years on rooftops taught her what textbooks couldn’t. That background shows up in how we handle Gelco repairs: we know the pre-2016 liner gauge issue because we’ve pulled dozens of them, and we know the Kennesaw soil settlement pattern because we’ve measured it on camera.

Our 365-Day Done Right Promise covers every repair. Our Free Second Opinion policy means you can bring us any competitor’s written estimate and we’ll review it against what our camera found. And because we source Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials through Haven’s buying network, we don’t push one brand when another fits the repair better.
