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.
Gelco Fireplace Services in Southampton: What to Know First
As an independent Gelco service provider, Hearthstone Chimney Co. handles Gelco fireplace repair, gas fireplace service, and insert work throughout Southampton, with most calls scheduled within a few days and repairs typically wrapped in a single visit.

Call us at (516) 619-2915 when you’re ready to talk through what you’re seeing.

How Gelco Products Fail - and How We Fix Them
- Gelco Log Sets (GL- and GLS-Series): The ember bed degrades faster than owners expect, especially in Southampton’s salt-air environment where coastal humidity accelerates ceramic fiber breakdown. We see this in Noyack and North Sea homes where the set looks fine but throws half the radiant heat it used to. We replace with OEM-spec Gelco media or match the density grade precisely - a generic “universal” ember bed never burns right in these trays.
- Gelco Direct-Vent Fireplaces (GDV Series): The pilot assembly gums up with sulfur compounds from propane conversions, common in older Southampton Village homes originally plumbed for oil. The symptom is a pilot that lights but won’t hold, or a delayed main burner ignition that rattles the glass. We clean the orifice with the right gauge wire, never a drill bit, and we check the gas valve dropout with a manometer - not guesswork.
- Gelco Fireplace Inserts (GI-Series): The refractory panels crack from thermal shock when homeowners crank the blower after a cold start, which happens plenty in unheated Southampton cottages used weekends only. Hairline cracks we monitor; through-cracks we replace with Gelco-spec refractory or HeatShield resurfacing where the panel geometry allows. We photograph everything before we recommend either path.
- Gelco Damper Systems (GD-Rotary and GD-Top-Seal): The rotary chain seizes in coastal homes where the firebox cools damp for months, particularly after Southampton’s shoulder seasons. The top-seal gasket also hardens faster than inland specs predict. We free the mechanism with proper penetrating protocol, replace the gasket with high-temp silicone-rated material, and document the seal with a smoke test you can watch.
- Gelco Firebox Weldments (GW-Builder and GW-PreFab): Spot welds at the firebox floor corners fatigue from expansion cycling, worse in homes where the unit’s oversized for the square footage and run short-hot cycles. We find this in converted summer homes now heated year-round. Our repair is firebox replacement or engineered welding with 309 stainless rod, followed by a Level-2 camera inspection to confirm no hidden breach.
Our Gelco Fireplace Services Process
- 1
You call, a live person answers. No voicemail, no callback queue. We ask what you’re seeing, what model you have if you know it, and when you’re home.
- 2
We arrive on time, uniformed, background-checked. Technician boots off, lays runners, and walks the unit with you before touching tools.
- 3
Level-2 camera inspection and combustion test. We run a visual scope up the flue, check gas pressure and CO output, and photograph what we find. You see the images on the spot.
- 4
Plain-English verdict, upfront price. We tell you what’s wrong, what we recommend, what we could defer, and what it costs. OEM Gelco part or quality aftermarket - we explain the trade-off and let you decide.
- 5
The repair, the test, the cleanup. Most Gelco jobs finish in one visit. We fire the unit, verify operation, and leave the hearth cleaner than we found it.
- 6
Written 90-Day Done Right Promise. If it’s not right, we come back. No paperwork to dig up, no argument.
What Gelco Fireplace Services Costs in Southampton
Southampton runs higher than national averages for fireplace service - travel, coastal insurance, and the reality that many homes here aren’t on year-round maintenance schedules.
- Gelco gas fireplace tune-up and safety check: $89 (seasonal special)
- Pilot assembly cleaning or replacement: $180-$290
- Ember bed / log set replacement: $340-$580 depending on series size

- Firebox weld repair or replacement: $1,200-$2,400
- Full insert removal and replacement: $2,800-$4,500
What moves the price: access (crawl space, tight chase, second-story flue), part availability (some older Gelco GI-series panels are special-order), and what we find once we’re inside. We don’t pad estimates. Call (516) 619-2915 for a free, exact quote.
Why Southampton Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been sweeping and repairing chimneys from the South Fork to the North Shore since 1984. Russell Haines and our crew know the difference between a Gelco GDV-33 and a GDV-40 without checking the manual, and we stock the common failure parts so you’re not waiting two weeks for a pilot orifice in burning season.
Our Level-2 inspections end with photos you can see and a verdict you can understand. The 90-Day Done Right Promise is in writing, no arguing. We also work with DuraFlex liner systems and HeatShield resurfacing when a Gelco repair ties into broader chimney needs, so you’re not coordinating multiple contractors. A clean flue does the talking - you just need a warm fire to hear it.
FAQs
No. As an independent Gelco service provider, we follow manufacturer service protocols and use OEM or equivalent-spec parts. Gelco’s warranty covers defects in materials and workmanship, not who performs routine service, provided the work is done to specification. We document our work with photos and serial numbers so you have a record if a warranty claim ever arises. Call (516) 619-2915 if you want us to review your warranty status before we book.
Common items - pilot assemblies, gaskets, ember media - we stock or can have within two to three business days. Older GI-series inserts and discontinued GW firebox panels may run seven to ten days. We tell you before we order, and we don’t charge until the part is in our hands and you’re confirmed for install.
Repair if the firebox is sound, the flue is properly sized, and the repair cost is under half the price of a comparable new unit. Replace if the firebox is cracked through multiple planes, the unit is pre-1990 and parts are obsolete, or you’ve already sunk repair money into it twice in five years. We’ll show you the camera footage and give you both numbers so you decide.
Annually, before the first fire of the season. Gas burns cleaner than wood but produces acidic condensation that corrodes burners and fogs glass. In Southampton’s coastal climate, we’ve seen pilot orifices partially obstructed in a single off-season. The $89 seasonal tune-up catches this before it becomes a no-heat call in January.
Deferred maintenance on a gas unit risks delayed ignition, elevated carbon monoxide, and eventually a failed gas valve or blower motor - repairs that cost five to ten times the tune-up. On wood-burning Gelco inserts, creosote accumulation and cracked refractories can lead to a flue fire or combustion gas leak into living space. Neither is common, both are preventable, and we won’t tell you a cracked panel is an emergency if it isn’t. Call (516) 619-2915 for an honest assessment.
