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 New City: What to Know First
We provide independent Gelco fireplace services in New City, with most repairs completed in a single visit and upfront pricing that matches the final invoice. A standard Gelco gas fireplace service runs $180-$280, while firebox or damper repairs on Gelco wood-burning units typically fall between $320-$650 depending on parts. We’re Hearthstone Chimney Co., and we’ve been working on Gelco products in Rockland County homes for years, including regular calls from neighborhoods near New City’s Veterans Memorial Park and up toward the Tappan Zee corridor. If you own a Gelco fireplace, insert, or gas unit that isn’t drafting right, won’t stay lit, or has developed an odor, call us at (845) 599-0930. A live person answers, and estimates are free.

How Gelco Products Fail - and How We Fix Them
- Gelco gas fireplace inserts (GI-series): The pilot assembly on GI-series inserts is prone to sooting in New City’s hard-water zone, where mineral content accelerates thermocouple degradation. We see this every fall in homes near Lake DeForest. We clean the pilot orifice with proper airflow gauges, replace the thermocouple with an OEM-spec part rated for 250,000 cycles, and test flame rectification before we leave.
- Gelco prefab wood-burning fireplaces (Presto series): The refractory panels in Presto fireboxes develop hairline cracks from thermal cycling, especially when homeowners burn green or unseasoned wood, which is common in New City where seasoned hardwood delivery runs thin by February. We source Gelco-spec refractory or upgrade to HeatShield cerfractory foam when the panel substrate is too far gone, always documenting with photos.
- Gelco top-sealing dampers: The stainless cable on Gelco top dampers seizes after 8-12 years of Rockland County freeze-thaw, particularly on north-facing chimneys that never fully dry. We don’t just lubricate and hope. We drop the damper, inspect the frame for galvanic corrosion at the Gelco-aluminum junction, and replace with a matched Gelco assembly or a Famco equivalent when the flue profile demands it.
- Gelco direct-vent gas fireplaces: The pressure switch on older Gelco direct-vent units misreads when the intake/exhaust termination gets spider-webbed or was installed too close to shrubbery, a frequent issue in New City’s mature neighborhoods with heavy landscaping. We pull the termination, measure actual draft with a digital manometer, and reset the switch to factory spec rather than bypassing it.
- Gelco fireplace doors and enclosures: The tempered glass on Gelco enclosures shatters from over-tightening during homeowner cleaning or from thermal shock when a cold gust hits a hot fire. We measure the exact Gelco glass spec, including the etched part number most owners miss, and install with proper gasket compression so the door seals without stressing the pane.
Our Gelco Fireplace Services Process
- 1
Call intake: A live person answers, notes your Gelco model or series if you know it, and schedules a window. We don’t do voicemail queues.
- 2
Level-2 camera inspection: Our tech arrives in uniform, runs a visual and camera inspection of the firebox, flue, and damper, and photographs every finding. You see the images on a tablet while we explain what they mean in plain English.
- 3
Parts diagnosis: We identify whether your repair needs an OEM Gelco part, a quality aftermarket equivalent from our DuraFlex or Famco inventory, or a HeatShield application. We explain the trade-off and price each option before you decide.
- 4
Repair and testing: Most Gelco repairs finish in one visit. Gas units get combustion analysis. Wood units get a draft test. Dampers get cycle-counted. If it’s not right, we don’t leave until it is.
- 5
Documentation and guarantee: You receive photos, a written verdict, and the 90-Day Done Right Promise in writing. If something isn’t right, we make it right. No paperwork to dig up, no arguing.
- 6
Cleanup and close: We tarp the work area, haul debris, and leave the hearth as we found it. The price matches the estimate.

Why New City Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been serving New City and Rockland County for over 42 years, and we’ve worked on Gelco products since they were a dominant line in the 1990s builds around here. Our techs know the difference between a Presto and a GI-series without reading the tag twice. We carry DuraFlex liner material, HeatShield refractory, and Famco dampers on our trucks, so we’re not ordering parts and making you wait. Every job gets the 90-Day Done Right Promise in writing, and our phones are answered by a live person 24 hours a day. Russell Haines built this company on the idea that a chimney sweep should explain what he found the way he’d want it explained to his own father: direct, complete, and without a sales pitch hiding in it.
FAQs
No. As an independent Gelco service provider, we perform warranty-safe work using OEM-spec or equivalent parts, and we document everything. Gelco’s warranty covers manufacturing defects, not service provider choice. If your unit is still under original warranty, we note that in our report so any valid claim stays clean. Call (845) 599-0930 if you’re unsure about your warranty status.
Most common Gelco parts, pilot assemblies, thermocouples, and refractory panels, are in our regional supply chain and arrive within 2-3 business days if we don’t stock them. We carry DuraFlex, HeatShield, and Famco equivalents on our trucks for same-day completion when the application allows. We’ll tell you before we start whether your repair needs a special order.
Repair makes sense when the firebox and flue are structurally sound and the repair cost is under half the price of a quality new insert. We replace Gelco units when the refractory is failing on multiple planes, the flue liner is compromised, or parts are obsolete. Our camera inspection gives you the data to decide. Estimates are free.
Once yearly, before the burning season starts. New City’s cold snaps come early some years, and a gas fireplace that sat idle all summer can develop spider webs in the orifice, valve stiffness, or venting issues. Annual service catches these before they become no-heat calls in January.
creosote accumulates, the draft degrades, and the risk of chimney fire or carbon monoxide spillage rises. In New City’s climate, freeze-thaw cycles also accelerate crown and flue damage when water mixes with acidic creosote. We find most neglected Gelco Presto units need refractory work by year 15. A seasonal sweep and inspection costs far less. Call (845) 599-0930 for an exact quote.
