Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Liner & Rebuild in Alpharetta: What to Know First
We provide independent Gelco chimney liner and rebuild service in Alpharetta, with most Gelco liner replacements and partial rebuilds completed in one to two days after inspection. Every job starts with a written price, a written scope, and a written warranty before any work begins - no exceptions. This page is for Gelco owners in Alpharetta who need straight information on what fails, what it costs, and who can fix it without the sales theater. Call (678) 679-0171 for a free estimate or a free second opinion on any written quote you’ve already received.
How Gelco Products Fail - and How We Fix Them
- Gelco stainless liners (3003 and 316Ti series) with crevice corrosion at the collar weld. Alpharetta’s clay-heavy soil and seasonal humidity swings accelerate electrolytic action where the collar meets the flue tile. We cut back to sound metal, sleeve with a DuraFlex 316Ti corrugated section, and document the weld with photos under Haven Standard Clause 4.
- Gelco flexible liners (ProFlex and UltraFlex) that have lost wall tension after 12-15 years. The corrugations flatten in the offset section, creating a trap for condensation and acidic creosote. We don’t try to re-tension - we pull a new liner, sized to the appliance’s BTU output, and show you the collapsed section on camera before we quote.
- Gelco rigid liner systems with spalled refractory panels in the smoke chamber. The panels were never designed to take direct flame impingement from an overfiring insert. We replace with HeatShield Cerfractory foam or source OEM Gelco panels if the series is still supported, and we tell you which option costs what before we order.
- Gelco top-mount dampers (TD series) seized open or shut due to cable corrosion. The stainless cable runs through a cast-aluminum frame that galvanically corrodes in Alpharetta’s pollen-acid rain cycle. We can rebuild the frame with a Famco stainless replacement or convert to a lock-top damper - your call, priced both ways in writing.
- Gelco chimney caps with failed mesh-to-frame welds after ice events. Alpharetta’s freeze-thaw in January and February builds ice in the mesh, and the cheap MIG welds on older Gelco caps pop. We fabricate a replacement in copper or stainless through Copperfield, or source a current Gelco cap if you want to stay OEM. Either way, the new cap gets a lifetime warranty on craftsmanship.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book your NFPA 211 Level 2 inspection with camera scan.
- 2
Inspection and documentation. Corrine or one of our techs runs the camera down the flue, records the footage, and notes the Gelco series, model, and condition. The camera doesn’t soften anything, and neither do I.
- 3
Written quote with parts specified. We list OEM Gelco parts and quality aftermarket alternatives (DuraFlex, HeatShield) with the real price difference. You choose before we order.
- 4
Repair or rebuild. Background-checked, uniformed technicians arrive on schedule with license numbers visible. Work proceeds per the written scope - no additions without a second written approval.
- 5
Testing and photo record. We pressure-test or smoke-test the liner, document the completed work with photos, and upload to your record under Haven Standard Clause 4.
- 6
Warranty and follow-up. The 365-Day Done Right Promise is stamped on your invoice. If it’s not right, we make it right.

| Service | Typical Range |

What moves the price: flue height, accessibility (steep Alpharetta roofs off Webb Bridge Road add time), whether the existing liner is extractable or has to be demolished in place, and if the smoke chamber needs parging. We don’t guess - we camera-inspect, then write the number. Call (678) 679-0171 for your exact quote; estimates are free.
Why Alpharetta Homeowners Call Emberly Chimney Cleaners Alpharetta for Gelco Work
We’ve worked Gelco systems across Alpharetta long enough to know which builder installed which series in which subdivision, and what that means for your repair. Corrine Halstead learned this trade in New York and has spent the better part of two decades running chimneys across the Atlanta metro, including steady jobs off Webb Bridge Road near Wills Park. Our techs don’t sell - they show you the camera footage, name the finding, and write the price. If another company has already given you a quote, we’ll review it free and tell you straight if it’s fair. The 365-Day Done Right Promise, background-checked crews, and live phone support 24/7 are standard, not upgrades.
FAQs
No - Gelco’s warranty covers manufacturing defects, not who installs or services the product. As an independent Gelco service provider, we document our work to manufacturer specs so any legitimate defect claim stays valid. If you have a concern, call us at (678) 679-0171 and we’ll walk you through the documentation you’ll need.
Yes, for most series made after 2005. For discontinued lines, we source compatible DuraFlex or HeatShield components that meet or exceed Gelco’s original spec, and we price both options in writing before ordering. Call (678) 679-0171 to confirm availability for your specific model.
We camera-scan to find the answer - anything else is guessing. If the damage is isolated to a collar, offset, or short section, we repair. If the wall has thinned below 24 gauge equivalent, or if multiple seams are failing, we recommend replacement and show you the footage that proves it. Call (678) 679-0171 to schedule the inspection; estimates are free.
Most Gelco liner replacements in Alpharetta are completed in one day, with a second half-day for inspection and testing. Full rebuilds with masonry work typically run three to five days, depending on weather and scaffold needs. We give you a written timeline with the price before we start.
Not necessarily - gas inserts often require a smaller, properly sized liner rather than your existing wood-burning Gelco system. We measure the appliance output, camera the existing flue, and specify exactly what the conversion requires. Call (678) 679-0171 for a written scope and price before you buy the insert.
