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 Plainview: What to Know First
We provide independent Gelco fireplace services in Plainview, 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 work on older Gelco wood-burning units typically range from $340-$890 depending on parts. This page is for homeowners in Plainview who already own a Gelco fireplace or insert and need a technician who knows the difference between a Series 500 damper assembly and a Series 800 - not a generalist who orders parts and hopes.
We’ve worked on Gelco units from the split-levels near Manetto Hill Road to the ranch homes off Old Country Road, and we’ve learned which parts fail first in Plainview’s freeze-thaw cycles. If your Gelco fireplace is smoking, not drafting, or refusing to light, call us at (934) 348-4832. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them
- Series 500 gas inserts: pilot assembly failure. The OEM pilot bracket on early-2000s Series 500 units fatigues at the mounting flange after roughly 12-15 years of Plainview heating seasons. The pilot stays lit but drifts out of flame-sensor range, causing intermittent shutdowns. We replace with the updated bracket or a quality aftermarket equivalent, then verify millivolt output at the valve before we leave.
- Series 800 wood-burning fireplaces: refractory panel cracking. Gelco’s refractory panels in the Series 800 line are rated for thermal shock, but rapid temperature swings - common when Plainview homeowners burn on mild autumn nights, then let the fire die - cause hairline fractures that widen across seasons. We measure crack depth against NFPA 211 standards; shallow surface cracks get high-temp repair, deep fractures get factory-matched replacement panels.
- Pre-fab chimney systems: chase cover rust-through. Gelco’s galvanized chase covers from the 1990s and early 2000s develop pinhole leaks where the salt air from Long Island’s south shore meets freeze-thaw cycling. Water enters the chase, rusts the termination collar, and stains the firebox ceiling. We fabricate custom stainless chase covers in-house or source Gelco-compatible replacements, then inspect the flue liner with a camera before closing up.
- Series 600 fireplace inserts: blower motor bearing failure. The OEM blower on Series 600 inserts runs at a fixed speed and accumulates dust from Plainview’s pollen-heavy springs. Bearing noise starts as a whine, progresses to vibration, then seizes. We clean the housing, test amperage draw, and install either a Gelco-spec replacement or a sealed-bearing aftermarket unit with a 10-year motor warranty.
- Damper assemblies across all wood-burning lines: throat plate warping. Gelco’s cast-iron throat dampers warp when homeowners burn unseasoned wood, which is common in Plainview where oak and maple are abundant but improperly stored. A warped damper doesn’t seat fully, bleeding heat up the flue and letting cold air down. We lap-fit the plate, replace the frame if it’s out of square, or convert to a top-sealing damper when the throat is too damaged for reliable repair.
Our Gelco Fireplace Services Process
- 1
Call intake. A live person answers, notes your Gelco model and symptoms, and schedules a window. We ask for the serial number if you have it - saves twenty minutes on site.
- 2
Level-2 camera inspection. Our technician arrives uniformed and background-checked, sets drop cloths, and runs a camera through the flue or inspects the gas train. You see the footage on a tablet; we explain what we’re seeing in plain English.
- 3
Parts decision. For discontinued Gelco components, we source OEM remaining stock when available or specify quality aftermarket from our trusted brands - HeatShield for refractory, DuraFlex for liner sections - and tell you which we’re using and why.
- 4
Repair with test. We complete the work, pressure-test gas connections, or run a combustion analysis on wood units. The firebox gets vacuumed, glass gets cleaned, and we verify draft with a manometer.
- 5
Documentation and guarantee. You receive photos from the inspection, a written verdict, and our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.

Why Plainview Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering calls with a live person for over 42 years, and we’ve learned that Gelco owners in Plainview don’t want a sales pitch - they want someone who recognizes their unit from the serial number prefix and knows whether the part is still made. Russell Haines learned the trade at Los Angeles Trade-Technical College before spending the better part of two decades running a brush down chimneys across Long Island, including plenty of homes near the Old Country Road corridor. He’s built a reputation for finding the thing the last guy missed.
Our technicians carry Gelco-compatible inventory and the backup of professional-grade brands: DuraFlex for liner work, HeatShield for refractory repair, Olympia Chimney for termination components. Most jobs finish in one visit. Our 90-Day Done Right Promise means if it’s not right, we make it right - in writing, no arguing. If the chimney is doing its job, you won’t think about it once all winter - that’s exactly the point.
FAQs
No - as an independent Gelco service provider, our work does not void any remaining manufacturer warranty on the appliance itself, provided we use compatible parts and follow installation standards. Gelco’s warranty on original components expires after the stated term regardless of who services the unit. We document every part source and procedure so your coverage remains intact where it applies. Call (934) 348-4832 if you’d like us to review your warranty status before booking.
Yes, for most lines through the early 2000s, though some Series 500 and 800 components are discontinued by the manufacturer. We maintain relationships with regional distributors who hold remaining OEM stock, and we specify quality aftermarket alternatives - from HeatShield, DuraFlex, or Olympia Chimney - when factory parts are exhausted. We never install a substitute without explaining the trade-off and getting your approval. For a parts check on your specific model, call (934) 348-4832 with your serial number.
Replacement becomes necessary when the firebox or heat exchanger is structurally compromised beyond safe repair, or when repair costs exceed 60% of a new installed unit. Most Gelco issues we see in Plainview - damper failure, refractory cracking, gas valve problems - are repairable. We make this call only after camera inspection and photos you can see, never from a cursory look. If replacement is the honest recommendation, we’ll say so and explain why. Call (934) 348-4832 for an inspection - estimates are free.
Once per year, per NFPA 211, regardless of how little you think you burned. Plainview’s oak and maple produce more creosote than western softwoods, and Gelco’s refractory panels develop stress cracks that are invisible until a camera finds them. Annual service catches both. We also check the termination cap for bee and bird nests, which are common in Nassau County’s mature tree canopy. Call (934) 348-4832 to schedule before burning season.
Deferred maintenance leads to three predictable problems: delayed ignition from dirty burners, which can damage the firebox; failed safety components like the thermocouple or spill switch; and venting degradation from corroded terminations, raising carbon monoxide risk. Gelco gas units don’t warn you - they just fail, usually on the coldest night. A $180 tune-up prevents the $600 emergency call. Call (934) 348-4832 to book.
Ready to get your Gelco fireplace working right? Call (934) 348-4832 - a live person answers, 24 hours a day, 7 days a week - and we’ll schedule your free estimate in Plainview.
