This page is for homeowners in Dix Hills and the Half Hollow Hills area who have a Gelco factory-built fireplace or chimney and want an honest cleaning from somebody who works on them regularly. Wendell Pike and his crew have been inside enough Gelco flues around here to know where they fail, what they tolerate, and when they can go another season without being touched.

How Gelco Products Fail - and How We Fix Them

Gelco made a lot of prefab chimneys in the 1980s and 1990s, and a good number of them are still burning in Dix Hills homes. They were built decently for their era, but they’re old now, and age shows up in predictable places. Here’s what we actually find:

• Gelco air-cooled chimney flue warping. Most Gelco systems in Dix Hills use air-cooled stainless flue sections rather than insulated pipe. After 25-plus years of heating and cooling cycles, those inner walls can warp or separate at the seams. You won’t see it from the firebox, but a camera will catch it every time. We flag it, show you the footage, and tell you whether it’s still safe to run. If it’s not, we talk replacement options, often with DuraFlex or HeatShield liners that fit the existing chase.
• Creosote buildup at the offset elbows. Gelco factory-built chimneys frequently have offsets where the flue jogs to get around a floor joist or roofline. Creosote collects in those elbows faster than anywhere else. A straight-brush sweep from a franchise outfit can leave those offsets untouched. We sweep with the right brush for the job and check the elbows with a camera before we call it done.
• Chase top and cap deterioration. The metal chase covers on Dix Hills Gelco installations take a beating from salt air off the Sound and freezing winters. When the chase top rusts through, water gets in, and water ruins the flue liner and the firebrick below. We see it on Gelco systems more than most other prefab brands from that era. A replacement cap is cheap insurance compared to a liner rebuild.
• Firebrick panels cracking behind the grate. Gelco fireplaces used refractory panels that don’t stand up well to years of heat and the occasional log rolled too far back. Cracked panels let heat reach the metal shell, and that’s how you get a warped firebox. We carry replacement refractory panels for common Gelco models and can swap them same day in most Dix Hills homes.
• Damper linkage seizing. The damper mechanisms on older Gelco units weren’t built for thirty years of use. They seize, or the handle gets loose, and then the fireplace drafts poorly or smoke spills into the room. Half the time a homeowner thinks they need a new fireplace when what they need is a $40 damper part and fifteen minutes of work. We’ll tell you the difference.

Our Gelco Chimney Cleaning & Sweep Process

You call, a real person answers, and we set a time. Wendell or one of his crew shows up in a uniform, on time, with a window that doesn’t slip. Then the work:

1. 1
   The look-around. Before anything gets swept, we inspect the firebox, damper, and the visible flue from below. Takes ten minutes. If we spot something that changes the job, you hear about it before we start, not after.
2. 2
   The camera run. We send a camera up the flue to see what’s really there. On a Gelco chimney, this is where we catch seam separation, elbow buildup, or rust that a brush alone would miss. You see the footage.
3. 3
   The sweep. We use brushes sized to your flue, not whatever’s on the truck. Gelco flues run smaller than most masonry chimneys, so the right brush matters. We sweep from the firebox up and from the top down when needed.
4. 4
   The parts call. If the sweep turns up a bad damper, cracked refractory panel, or a rusted cap, we tell you what it costs to fix and whether it can wait. We use OEM Gelco parts when they’re available. When they’re not, we use quality aftermarket pieces from DuraFlex or HeatShield and tell you exactly what we’re putting in and why.
5. 5
   The test and the guarantee. We check the draft, make sure the damper works, and leave the area cleaner than we found it. Every Gelco job gets the 90-Day Done Right Promise in writing. If something’s not right, one call brings us back.

What Gelco Chimney Cleaning & Sweep Costs in Dix Hills

Straight numbers, no games:

• Chimney sweep, no surprises: $189 to $329, depending on flue length and how long it’s been since the last cleaning. Includes camera inspection.
• Sweep plus damper replacement: $60 to $140 for the part, $40 to $80 for labor on top of the sweep. Most Gelco dampers are simple swaps.
• Refractory panel replacement: $90 to $180 per panel plus labor, depending on the Gelco model. Most fireplaces need one to two panels.
• Chase cover replacement: $220 to $380 including install, depending on the dimensions of the chase. We measure, we quote, we stick to it.

What moves the price on a Gelco job is flue height, how much creosote has built up, and whether the unit is original from the 1980s or a later replacement. Call (631) 318-8656 for a free estimate. The number you hear on the phone is the number on the invoice.
