This is for Alpharetta homeowners with Gelco-brand chimney components: caps, dampers, chase covers, and related hardware. We’re not affiliated with Gelco, which means we won’t pretend a repair is “factory authorized” and we won’t mark up parts for the label. We’ll tell you what the part does, what failed, and whether the fix is a repair or a replacement. Call (762) 600-1468 and a live person answers. Tell me what’s in the flue, and I’ll tell you what it takes to fix it.

How Gelco Products Fail – and How We Fix Them

Gelco makes solid chimney hardware. But Alpharetta’s weather, hard water, and a decade of Georgia humidity find the weak points in any metal component. Here are the five failures we see most often with Gelco parts in this area, and how we address each one.

• Gelco chase cover rust-through at the corners. Gelco chase covers are typically galvanized or stainless. The galvanized ones fail first at the corners, where water pools. We see it in homes off Kimball Bridge Road and Windward Parkway that catch consistent afternoon sun and evening condensation. Fix: replace with a stainless cover sized to the chase, sealed at the seams. If flue penetration points are involved, we repair the collar rather than patch around it.
• Gelco multi-flue cap screen clogging. Gelco caps with wire mesh screens do their job keeping animals out, but Alpharetta’s oak pollen and creosote dust pack the screen fast. A clogged screen restricts draft, and the fireplace smokes back into the room. Homeowners often assume the flue is blocked when it’s just the cap. Fix: we pull the cap, clean the screen, inspect the mesh for warping, and remount or replace. If the screen is torn, we quote a replacement panel rather than a whole new cap when the frame is sound.
• Gelco top-sealing damper cable failure. Gelco top-mount dampers use a cable that runs down the flue to a handle or wall lever. The cable rusts or kinks after years of heat cycles. Symptom an owner would notice: the handle spins or feels loose, and the damper won’t stay closed. Fix: we replace the cable assembly, not just the handle. A cable that’s stretched beyond adjustment needs a full damper swap. We quote that honestly before touching anything.
• Gelco cap flashing joint separation. Where a Gelco cap meets the flue or chase, the flashing adhesive or sealant fails after years of expansion and contraction. Water gets in around the edges and runs down the chimney structure. This is the most misdiagnosed issue in Alpharetta, because it looks like a roof leak. Fix: we strip the old sealant, inspect the metal for corrosion, and re-flash the joint properly. If the cap itself is warped, no amount of sealant holds long, and we say so.
• Gelco stainless steel pitting from alkaline water. Alpharetta’s water is hard and slightly alkaline. Over years, stainless Gelco hardware exposed to sprinkler overspray develops pitting, and those pits eventually become pinhole leaks. We see this on Gatsby-style chimneys and chase covers on larger homes near the Manor and the Country Club of the South. Fix: if pitting is surface-level, we repack and seal. If pinholes have formed, the part has failed and we recommend replacement with a thicker-gauge stainless product.

Our Gelco Chimney Repair Process

A Gelco job from Flint Chimney Co Alpharetta runs like this:

1. 1
   Call and talk to a person. We answer, we ask what’s happening with the chimney, and we schedule a time window.
2. 2
   On-site diagnosis. Our technician inspects the Gelco component, documents what he sees with photos, and explains it in plain words.
3. 3
   Written price before work. You approve a dollar figure. It’s the number you pay, no matter what we find inside the chase or flue.
4. 4

5. 5
   The repair. We complete the fix, clean the work area, and do a quick visual confirmation that water and draft move the right way.
6. 6
   Guarantee in writing. Every repair carries our 365-Day Done Right Promise. If it fails within one year, we return at no charge. No argument, no second invoice.

Why Alpharetta Homeowners Call Flint Chimney Co Alpharetta for Gelco Work

Because we operate under The Garrison Standard, the same code every Garrison Partners location follows. Every Gelco repair gets a written price before work starts, every repair carries a one-year written guarantee, and every technician who walks through your door is background-checked and uniformed. That’s the whole promise.

We’ve been at this since 2002 as part of the Garrison Partners family. We know Gelco hardware, but we also work daily with DuraFlex liners and HeatShield systems, so when a Gelco failure traces back to a flue or liner issue, we’re not guessing at the next step. We fix the cap and we fix the flue it’s mounted to. That’s the difference between a patch job and a chimney that’s right for years.
