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 Flushing: What to Know First
We provide independent Gelco fireplace services in Flushing, with most repairs completed in a single visit and upfront pricing agreed before any work begins. A standard Gelco gas fireplace service runs $180-$280; firebox repairs or damper replacements on older Gelco wood-burning units typically fall between $340-$890 depending on parts. This page is for homeowners in Flushing who own a Gelco fireplace, insert, or gas log set and need a technician who knows the difference between a Series 38 damper and a Series 42 - and won’t treat either like a generic part. We’ve been working on Gelco products in Queens for years, including the pre-war brick homes near Kissena Park where these units often outlast everything else in the house except the foundation. Call (516) 206-6672 to speak with a live person, any hour, any day.

How Gelco Products Fail - and How We Fix Them
- Series 38 direct-vent gas fireplaces: pilot assembly carbon buildup. The SIT 820 valve and pilot combination in Series 38 units tends to accumulate carbon flakes from Flushing’s variable gas pressure, especially in homes near the Con Ed mains along Main Street. The pilot lights, then drops out after ten minutes. We disassemble the pilot hood, clean the orifice with a numbered drill bit (never a wire brush, which enlarges the bore), and test flame rectification with a microamp meter. If the thermopile reads below 325 mV, we replace it with an OEM SIT component, not a universal fit.
- Series 42 wood-burning fireplace inserts: refractory panel cracking. The rear and side refractory panels in Series 42 inserts develop hairline cracks from thermal cycling, particularly in Flushing’s older homes where the chimney runs exterior and experiences wider temperature swings. A cracked panel redirects heat toward the steel wrapper, warping it over time. We measure panel thickness with a micrometer - Gelco spec is 1-1/4″ - and source replacement panels through Copperfield’s Gelco-compatible line when OEM backorders stretch past three weeks.
- Gelco gas log sets: failed on/off remote receiver. The early 2010s RPK-2 remote kits use a 433 MHz receiver that loses pairing after power interruptions, common in the overhead transformer neighborhoods of north Flushing. Homeowners press the remote, hear the valve click, get no flame. We test signal strength at the receiver location; if interference from nearby WiFi mesh networks is the culprit, we relocate the receiver or upgrade to a current Skytech 3301-P kit with better shielding.
- Series 50 see-through fireplaces: draft inducer motor bearing failure. The FASCO draft inducer on Series 50 units runs at 3400 RPM and develops bearing noise after roughly eight to ten years of Flushing’s humid summers and dry radiator heat in winter. The motor still spins, but vibration loosens the exhaust collar gasket. We replace with an OEM FASCO or a Regal-Beloit cross-reference of matching RPM and amperage draw, never a generic HVAC blower that overheats in fireplace duty cycles.
- Gelco top-sealing dampers: cable sheath corrosion. The stainless aircraft cable on Gelco top-mount dampers corrodes at the point where it exits the chimney cap, especially on Flushing homes within a half-mile of the LIRR where airborne brake dust accelerates oxidation. The damper won’t open fully, or the handle spins free. We pull the entire cable assembly, inspect the cast-aluminum frame for galvanic corrosion where stainless meets aluminum, and replace with a complete Gelco cable-and-frame kit or a Lock-Top equivalent if the flue tile lip is damaged.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, notes the Gelco model number from the rating plate (usually inside the firebox or behind the lower louver), and books a window. No app, no callback queue.
- 2
Level-2 camera inspection. Our technician arrives in uniform, runs a chimney camera, and photographs the flue, firebox, and damper. You see the images on a tablet while we explain what we’re looking at.
- 3
Diagnosis and parts decision. We identify the failure, check OEM Gelco availability through our Copperfield and Famco distributors, and quote OEM versus quality aftermarket options. You choose before any work starts.
- 4
Repair with test firing. We complete the repair, then run the unit through three full heat cycles - startup, operating temperature, and cooldown - verifying gas pressure, draft, and safety shutoff function.
- 5
Documentation and guarantee. You receive photos, a plain-English verdict, and the 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork to find, no arguing.
- 6
Cleanup and close. We leave the work area as we found it, with the final invoice matching the upfront number.

Flushing’s older housing stock - particularly the brick row houses with exterior chimney chases - can add labor time if we need to access a frozen cleanout door or remove a rusted chimney cap. We tell you before we start. Estimates are free. Call (516) 206-6672 for an exact quote on your Gelco unit.
Why Flushing Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Flushing thirty years from now. That changes how we treat a customer. Our technicians are background-checked, uniformed, and carry the parts to finish most Gelco jobs in one visit - no “we’ll order that and come back.” Every inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, no arguing: if it’s not right, we make it right. We also work with DuraFlex and HeatShield when a Gelco repair crosses into liner or masonry territory, so you’re not handed off to another contractor. A clean flue isn’t a luxury. It’s just the job done right.
FAQs
No - as an independent Gelco service provider, we do not void factory warranties provided we use OEM or manufacturer-approved parts and follow installation guidelines. Gelco’s warranty covers defects in materials and workmanship; it does not require factory-authorized service for routine maintenance or repair. We document every part number and torque spec in case you need warranty support later. Call (516) 206-6672 if you want us to review your warranty paperwork before scheduling.
Common items - thermocouples, pilot assemblies, refractory panels for current Series 38 and 42 units - ship from our Copperfield and Famco distributors within two to three business days. Discontinued Series 20 and 30 components may take five to seven days or require us to fabricate a compatible solution from HeatShield or DuraFlex materials. We tell you the lead time in the upfront estimate, before you commit.
Repair if the firebox wrapper is sound, the flue liner is intact, and parts remain available - most Gelco units built after 1995 qualify. Replace if the steel firebox is warped or rusted through, or if the cost of repair exceeds 60% of a new insert installed. We give you the camera evidence either way, with no pressure to choose replacement. Call (516) 206-6672 for a free second opinion if another contractor has recommended replacement.
Annually, per NFPA 211, even if you use it only for ambiance. Flushing’s gas supply carries trace moisture and particulate that foul burner ports and corrode ignition components. An $89 seasonal tune-up catches pilot drift before it becomes a no-heat call in January. Skipping service risks delayed ignition, sooting, or carbon monoxide spillage from a cracked heat exchanger we could have found with a camera.
Stage 3 glazed creosote builds up, especially on slow-burning overnight fires common in Flushing’s drafty pre-war homes. Glazed creosote ignites at 451°F and burns at 2000°F, cracking flue tiles and threatening the roof structure. We remove it with rotary chains or chemical treatment, but prevention is cheaper. If you burn three or more cords a season, sweep mid-season. Call (516) 206-6672 to book - estimates are free.
