This page is for Long Island homeowners who have a Gelco chimney system and want straight answers about what’s wrong, what it costs, and whether it even needs fixing. We’re an independent Gelco service provider, not a manufacturer-authorized shop, which means we’ll tell you when a problem can wait and when it can’t.

How Gelco Products Fail - and How We Fix Them

Gelco makes solid chimney products, but every brand has its failure points. On Long Island, with freeze-thaw cycles pushing water into brick and mortar all winter, we see the same issues repeat. Here’s what shows up on Gelco systems and what we do about it.

• Gelco stainless steel liners (the single-wall and flexible series) get pinhole corrosion at the seams. This happens when flue gases condense at the top of the liner, especially in uninsulated chimneys on the north side of a house. The fix is usually a liner section replacement, not a full rebuild. We’ll show you the corrosion on camera before we quote a dollar.
• Gelco chimney caps and chase covers in coastal Long Island towns rust faster than anywhere else. Salt air from the Atlantic gets into the hardware and works on the seams. We replace cap assemblies with marine-grade stainless fasteners and seal the chase cover with a bead that actually holds up in salt spray.
• Gelco prefabricated fireplace chimneys - the air-cooled and insulated models - develop cracks in the refractory panels. The panels are sacrificial by design, but when they crack, heat reaches the chimney wall. We replace panels with OEM-spec ceramic refractory and air-gap the replacement so it expands without binding.
• The Gelco offset elbows and coupling bands loosen over time, especially after rough winters. The bands slip, the joints separate slightly, and exhaust gases leak into the chase. We re-seat the joints, torque the bands to spec, and inspect the full run with a camera to confirm there’s no gap anywhere.
• Gelco chimney terminations - the rain caps and spark arrestors - clog with creosote or debris faster on Long Island than drier climates. The mesh screen catches everything. We clean the termination, and if the mesh is beginning to rot, we replace it before it falls into the flue.

Our Gelco Chimney Repair Process

1. 1
   You call, a person answers. That’s Wendell Pike or someone on the crew, not a call center. We ask what you’re seeing, and we give you a real arrival window.
2. 2
   We arrive and inspect the full system. We run a camera from the firebox to the termination. You see every frame. If your Gelco chimney only needs a sweep, Wendell will tell you that first.
3. 3
   We show you the problem and the parts decision. If a part needs replacing, we walk you through OEM vs. quality aftermarket. OEM parts keep warranties intact where that still applies; aftermarket parts from brands like DuraFlex or HeatShield sometimes fit better and cost less. You choose, with Wendell’s honest recommendation.
4. 4
   We quote the full price before work begins. No surprises at the invoice. The number you hear on the phone is the number you pay.
5. 5
   We do the repair and test it. We fire the system if it’s safe to test, run the camera again, and make sure the draft is working like it should.
6. 6
   We clean up, then we stamp the guarantee. Every job gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back at no additional cost.

What Gelco Chimney Repair Costs in Long Island

Here’s what Gelco chimney work typically runs on Long Island. These are honest ranges, not bait numbers.

• Repointing mortar joints on a Gelco masonry chimney - $450 to $1,200 depending on how much of the brick face is involved and how high the chimney is.
• Replacing a Gelco rain cap or spark arrestor - $175 to $450 installed, depending on the model and roof pitch.
• Replacing refractory panels in a Gelco prefab fireplace - $600 to $1,400 for a standard two-panel set, more if the firebox is large or the panels are uncommon.
• Liner section repair on a Gelco stainless steel flue - $800 to $2,000 depending on access and how much liner needs replacing.
• Chase cover or flashing repair on a Gelco unit - $350 to $900, more if the chase is tall or the flashing is embedded in roofing.

The price moves based on roof access, chimney height, and whether we’re matching an unusual Gelco part or switching to a better-fit aftermarket option. Every estimate is free, and we’ll give you the number in writing before work starts. Call (516) 968-5380 and we’ll get you an exact quote.
