A Emberly company - serving Alpharetta, GA

Gelco Fireplace Services 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 Fireplace Services in Alpharetta: What to Know First

We provide independent Gelco fireplace services in Alpharetta, from gas valve troubleshooting on the GL-550 series to firebox refractory replacement on older wood-burning units. Most Gelco jobs book within a week, and every one starts with a written price before any work begins - no exceptions. If you’re seeing delayed ignition on a Gelco insert, a stuck damper on a prefab wood unit, or you’re not sure whether your model is worth repairing, call us at (678) 679-0171 and we’ll schedule a camera inspection with a documented photo record under Haven Standard Clause 4.

How Gelco Products Fail - and How We Fix Them

  • GL-550 and GL-750 gas inserts: delayed ignition and “popping” on startup. The SIT 820 valve and pilot assembly on these mid-2000s units collect oxidation on the thermocouple connection, especially in Alpharetta’s humidity swings between March and October. The symptom sounds like a small explosion on startup. We pull the burner tray, clean the pilot orifice with a numbered drill bit (never a wire brush, which ovalizes it), and test millivolt output at the valve. If the thermopile reads below 325 mV under load, we replace it with an OEM SIT component - aftermarket thermopiles in this series tend to read high when cold and drop under sustained fire.
  • Prefabricated wood-burning fireplaces (Gelco FV-36, FV-42): cracked refractory panels. These factory-built units use 1-inch refractory cement panels that spider-web from thermal shock, usually after a chimney fire the owner didn’t know happened. The panels are no longer manufactured by Gelco, so we source HeatShield-compatible refractory or custom-cut panels through our Haven buying network. We photograph every crack under Clause 4 - hairline surface crazing is normal, but a crack you can fit a nickel into means replacement.
  • Gelco fireplace inserts in tight Alpharetta flues: smoke rollout on startup. Many Alpharetta homes off Webb Bridge Road and near Wills Park were built with 8×12 clay flue tiles that are technically oversized for a Gelco insert but functionally restricted by offset bends. The insert’s fan-assisted draft can’t overcome a cold, sluggish flue. We run a camera to map the flue’s actual path, then recommend a direct-connect liner (usually DuraFlex 316Ti) or a top-sealing damper to establish proper draft before the fan kicks on.
  • GL-100 and early gas log sets: deteriorating ember beds and sand pan corrosion. These 1990s units used steel sand pans that rust through where condensation collects - common in Alpharetta’s crawl spaces and basements with seasonal humidity above 70%. We replace the pan with a stainless equivalent, verify the gas orifice is still sized for the listed BTU input, and reset the ember bed with vermiculite and rock wool positioned to the manufacturer’s pattern. An incorrect ember bed causes sooting and CO risk.
  • Gelco chimney-top dampers: cable seizure and cap rust-through. The top-mount damper on Gelco wood units uses a 3/16-inch stainless cable that binds in the conduit after 10-15 years of pollen and creosote buildup - a real problem in Alpharetta’s oak-and-pine canopy. We free the cable with solvent and mechanical cleaning, or replace the entire damper assembly with a Lyemance or Lock-Top unit if the cast-aluminum frame has warped. The cap itself is often galvanized steel on older Gelco units; we upgrade to stainless or copper through our Copperfield supply line.

Our Gelco Fireplace Services Process

Our Gelco Fireplace Services Process
  1. 1
    Call and schedule. A live person answers, 24/7. We ask for the Gelco model number (usually on a metal tag inside the firebox or behind the lower louver) and the symptom. No model number? We work with photos.
  2. 2
    NFPA 211 Level 2 inspection with camera. Our tech runs a chimney camera down the flue and photographs the firebox, smoke chamber, and exterior termination. Corrine Halstead reviews the footage with you on-site or sends it by text - “The camera doesn’t soften anything, and neither do I.” You see what we see.
  3. 3
    Written price, written scope, written warranty. Before any tool touches your unit, you get a flat price with line items, the scope in plain language, and the 365-Day Done Right Promise stamped on the page. Haven Standard Clause 1 - have it in writing.
  4. 4
    Parts decision: OEM or quality aftermarket. For active Gelco lines, we quote OEM first. For discontinued series, we source through our Haven buying network (DuraFlex, HeatShield, Olympia Chimney, Famco, Copperfield) and tell you exactly what’s being installed and why.
  5. 5
    Repair, test, and document. We complete the work, run a combustion analysis on gas units or a smoke-pencil draft test on wood units, and add the photo record to your file under Clause 4.
  6. 6
    Cleanup and follow-up. Uniformed crew, floor protection, vacuum. You get the final invoice matching the written price, and we check in at 30 days.
