This page is for you if you own a Gelco fireplace, insert, or gas log set in Shelton and need service that doesn’t require explaining your brand to the technician. We stock common Gelco parts, carry DuraFlex and HeatShield materials for related chimney work, and we document every repair with photos you can see. Call (475) 265-6822 to speak with a live person, or read on for the specifics.

How Gelco Products Fail - and How We Fix Them

• Gelco GDV-series direct-vent gas fireplaces: delayed ignition or “popping” on startup. The GDV-25 and GDV-36 units we see in Huntington Center and White Hills split-levels often develop this symptom after 8-12 seasons. The cause is almost always degradation of the pilot assembly and flame sensor, compounded by Shelton’s swing-cycle winters that stress the ceramic igniter. We replace with OEM-spec pilot kits, test gas pressure at the manifold, and verify flame rectification before we leave. The fix holds because we check the root condition, not just the symptom.
• Gelco wood-burning fireplace inserts: cracked refractory panels and warped doors. The insert line popular in 1990s Shelton colonials near Booth Hill Road uses refractory cement panels that degrade faster when homeowners burn unseasoned hardwood, common in this area due to abundant local oak. We source Gelco-pattern panels or fabricate HeatShield refractory replacements when OEM is back-ordered, always measuring throat clearance to factory spec so the next fire doesn’t overheat the surround.
• Gelco chimney-top dampers: cable seizure and cap corrosion. The Gelco top-sealing damper with integrated cap is a smart design, but the stainless cable can freeze in its housing after years of Connecticut freeze-thaw, especially where pine needle debris accumulates in the Shelton woods. We free or replace the cable, lubricate with high-temp graphite, and inspect the silicone seal. If the cap is pitted, we match Gelco’s 304 stainless spec rather than substituting a lesser grade that won’t survive another decade on Long Island Sound’s corrosive air.
• Gelco gas log sets: sooting and odor complaints. The GL-18 and GL-24 vented sets installed in original Shelton fireplaces often produce carbon tracking when the burner port alignment shifts or the ember bed degrades. We disassemble, clean orifice by orifice, and replace ember material with Copperfield ceramic wool that matches Gelco’s radiant output. We also test draft with a manometer, because a smoking gas log set in a tight modern home usually points to negative pressure, not just a dirty burner.
• Gelco firebox walls: spalling and mortar joint failure. In the pre-1980s Shelton homes near the Housatonic, we’ve found Gelco fireboxes installed with standard Portland mortar instead of refractory mix. The thermal cycling destroys it. We rake and re-point with HeatShield refractory mortar, matching Gelco’s original wall thickness so the repair doesn’t create a cold spot that collects creosote. Russell Haines handles these personally when the firebox geometry is irregular; it’s the kind of job where “tell me what it is, fix what needs fixing, leave the rest alone” applies.

Our Gelco Fireplace Services Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask the model number if you have it, the symptoms, and whether the unit is gas or wood-burning. We give you a arrival window and a ballpark range.
2. 2
   On-site diagnosis with camera documentation. Our technician arrives in uniform, background-checked, with Gelco reference specs on tablet. We run a Level-2 camera inspection of the chimney flue when the fireplace connects to one, and we photograph the firebox, damper, and gas components. You see the images on screen.
3. 3
   Plain-English verdict and upfront pricing. We explain what’s wrong, what needs fixing now, what can wait, and what it costs. The number we quote is the number on the invoice. No surprises.
4. 4
   Parts decision: OEM or quality equivalent. For Gelco-specific components like pilot assemblies, door gaskets, and refractory panels, we prefer OEM when available and reasonably timed. For liner connections and crown work, we use DuraFlex or HeatShield materials that meet or exceed Gelco’s original spec. We note the choice on your invoice for warranty records.
5. 5
   Repair, test, and document. We complete the work, pressure-test gas lines, verify draft on wood units, and run a full burn cycle. Photos of the completed repair go to you by email or text.
6. 6
   Cleanup, guarantee, and next steps. We leave the work area as we found it. Your repair is covered by our 90-Day Done Right Promise, in writing, no arguing. If it’s not right, we come back.

Why Shelton Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been in Shelton long enough to know which Gelco models were installed by which builders, and what shortcuts those builders took. That matters when you’re diagnosing a GDV-36 that won’t stay lit in a White Hills colonial built in 1994.

Our 90-Day Done Right Promise means if we misdiagnose a part or the repair doesn’t hold, we make it right without paperwork or argument. Our technicians are background-checked, uniformed, and trained on Gelco’s specific ignition systems and venting configurations. We carry DuraFlex liner materials and HeatShield refractory products so we’re not waiting on a single supplier when your fireplace is out of commission in January.

A live person answers the phone, every hour of every day. We’ll be there when we say. Photos you can see, a plain-English verdict. That’s the square deal.
