Gelco Fireplace Services Nationwide

Gelco Fireplace Services in New Rochelle: What to Know First

We provide independent Gelco fireplace services in New Rochelle, with most repairs completed in a single visit and upfront pricing agreed before we start. A typical Gelco gas fireplace service runs $180-$340, while firebox or damper repairs on older Gelco wood-burning units range from $450-$1,200 depending on parts. We’re not affiliated with Gelco - we’re an independent service provider - which means we source the right part for your model, not whatever a factory rep wants to sell you.

Call (516) 927-2678

This page is for New Rochelle homeowners who already own a Gelco fireplace, insert, or gas log set and need it fixed, tuned, or converted. Maybe the pilot won’t stay lit on your Gelco GL-550. Maybe the damper in your 1990s Gelco wood burner hasn’t sealed since the last century. Or you’re wondering whether that insert in your Shore Road colonial is worth repairing. Call us at (516) 927-2678. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco GL-550 and GL-750 direct-vent gas fireplaces - intermittent pilot failure. The SIT valve on these mid-2000s units is sensitive to voltage fluctuation, and New Rochelle’s older wiring in neighborhoods like Wykagyl can drop below 24 millivolts under winter load. We test millivolt output at the thermopile under operating conditions, not just at rest. If the valve’s the culprit, we install an OEM SIT 820 Nova or a Robertshaw equivalent - both carry the same 1-year part warranty, and we’ll tell you which makes sense for how long you plan to keep the unit.
• Gelco wood-burning fireplace inserts (Pre-EPA models, 1985-1992) - cracked firebox refractory panels. These units were built with 1-inch thick refractory that degrades faster when burned with green or unseasoned wood, common in New Rochelle where homeowners still burn storm-felled oak from city tree removals. We measure panel thickness and crack width against NFPA 211; panels under 3/4 inch or with through-cracks get replaced with HeatShield factory-panel equivalents or genuine Gelco refractory if still available. We photograph everything before we quote.
• Gelco top-sealing dampers (model TD-2000 series) - cable seizure from coastal corrosion. The stainless cable on these dampers is 304-grade, not 316, and the salt air coming off Long Island Sound accelerates crevice corrosion where the cable enters the chimney cap housing. We’ve replaced seized TD-2000 cables in New Rochelle’s Neptune Island and Davenport Neck areas where the wind carries salt half a mile inland. We lubricate with high-temp graphite, replace with 316-grade cable where possible, or convert to a Lyemance or Lock-Top damper if the housing itself is compromised.
• Gelco vented gas log sets (GLV series) - sooting and odor from incomplete combustion. The GLV-24 and GLV-30 sets use a fixed orifice that clogs with spider webs or rust flakes from black iron pipe, especially in summer-dormant systems common in New Rochelle’s seasonal lake houses near Pine Brook. We pull the burner, check orifice diameter with a pin gauge, and clean the ember bed. If the odor persists, we combustion-test with a digital analyzer - CO over 100 ppm in the firebox means the gas pressure or primary air needs adjustment, not just a cleaning.
• Gelco fireplace-to-gas conversions (factory kits from the 1990s) - burner pan rust-through. The original Gelco conversion kits used aluminized steel burner pans that corrode from condensate when the chimney flue is oversized for the new gas input, a frequent issue in New Rochelle’s pre-war homes with 12×12 flue tiles. We inspect with a chimney camera before quoting any conversion repair. If the pan’s gone, we fabricate a replacement from 304 stainless or source a DuraFlex fire-gas insert that fits the existing firebox without the condensate problem.

Our Gelco Fireplace Services Process

1. 1
   You call, we answer. A live person, any hour. We ask for your Gelco model number (usually on a metal tag inside the firebox or behind the lower louver) and what’s happening. If it’s a no-heat call in January, we prioritize.
2. 2
   We arrive when we say. Background-checked, uniformed technician. Shoe covers, drop cloth, the whole thing. We inspect before we quote - always.
3. 3
   Camera inspection and diagnosis. For wood-burning units, we run a Level-2 camera up the flue. For gas units, we combustion-test and check gas pressure at the manifold. You see the photos. We explain what’s wrong, what can wait, and what was never a problem.
4. 4
   Parts decision, with options. OEM Gelco part, quality aftermarket equivalent, or upgrade to a compatible component from DuraFlex, HeatShield, or Famco. We explain the trade-off in writing, with prices. No surprises on the bill.
5. 5
   The repair, the test, the cleanup. We fix it, we fire it, we verify. Gas units get a combustion analysis printout. Wood units get a draft and smoke test. Then we vacuum, wipe, and leave it cleaner than we found it.
6. 6
   The 90-Day Done Right Promise. In writing. If it’s not right, we come back. No paperwork, no arguing. That’s the Keystone Standard.

Why New Rochelle Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been answering the phone with a live person for over 42 years. Russell Haines, our owner, has run his brush through flues across Westchester County for the better part of two decades, including plenty of older Colonial-era stacks in New Rochelle’s Beechmont neighborhood, where the mortar tells stories the owners never knew. He learned the trade hands-on after completing a vocational program at Los Angeles Trade-Technical College, then put in years of real-world work before the soot settled and chimney cleaning became his full-time calling.

We know Gelco products because we’ve repaired them, not because we read a manual. When a Gelco part is obsolete, we don’t shrug - we source from DuraFlex, HeatShield, or fabricate in stainless. Our 90-Day Done Right Promise is in writing, no arguing. Our technicians are background-checked and uniformed. Most jobs finish in one visit. And we document every inspection with photos you can see and a plain-English verdict.
