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 Chimney Liner & Rebuild in Newark: What to Know First
We repair and rebuild Gelco chimney liners across Newark, and most jobs are done in one to three days depending on whether we’re replacing a section or rebuilding the flue entirely. A straightforward Gelco liner replacement in Newark typically runs $2,200 to $4,800, while a full rebuild with new liner, crown work, and masonry repair can reach $7,000 to $12,000. You won’t get a factory line or a franchise price book here. You’ll get Wendell Pike and his crew, a camera inspection before anyone touches a brick, and a written quote that doesn’t change at the door. If you own a Gelco chimney liner and something’s off, call (848) 331-2638. If it needs doing, we’ll do it. If it doesn’t, we’ll tell you that instead.
This page is for Newark homeowners who already have a Gelco liner or are weighing one, and need straight answers on repair costs, failure signs, and whether a rebuild is really necessary. We’re an independent Gelco service provider, which means we fix what’s failing without a manufacturer’s script telling us to sell you a replacement.
Key Takeaways
- Gelco liners fail at the seams and the tee connection more often than the pipe itself.
- We don’t recommend a liner replacement until you’ve seen the camera footage yourself.
- A partial rebuild is often enough. We won’t sell you a full rebuild if the bottom courses are still solid.
- Every Gelco job in Newark gets our 90-Day Done Right Promise in writing.
How Gelco Products Fail - and How We Fix Them
Gelco makes a solid liner, but no liner survives Newark’s freeze-thaw cycles and salt air without some wear. Here’s what we actually find when we get up on Newark roofs and drop a camera down a Gelco flue.
- Gelco flexible liner seam separation at the furnace flue. The Gelco flexible liner runs through chimneys originally built for oil or wood, and the constant expansion-contraction from an 80% furnace cycling on and off in a Newark winter works the seam lock loose over time. We see separation most often in the lower third of the flue, near the appliance connector. The fix is a section splice with a Gelco-compatible connector and a full pull test, not a patch job that’ll fail next January.
- Tee-body pitting on Gelco stainless liners in older Newark rowhouses. In the Ironbound and the North Ward, the chimneys are short and the flue gases stay hot until they hit the tee, where they cool fast and sit. That’s where condensation eats at the tee body. A rusted Gelco tee will pass a visual from outside and fail a camera inspection from inside. We replace the tee with a stainless unit and check the liner above it for thinning before we call the job done.
- Kinked flex from a DIY drop or a cut-rate install. Flex liner doesn’t forgive a rushed install. If the liner was dropped from the top without a pulling cone and a guide at the bottom, it kinks where it passes the smoke shelf. A kinked Gelco liner drafts poorly, holds creosote, and can’t be cleaned properly. We pull the liner, assess whether the kink is compressible (rare) or structural (most), and replace the damaged run. No one should ever charge you to “straighten” a kinked liner.
- Cracked clay tile behind an intact Gelco liner. Newark’s old clay-tile chimneys are the real problem in half the Gelco rebuilds we do. The liner looks fine, but the tile behind it has cracked and spalled from decades of water and freeze damage. You can’t see it without pulling the liner. When we rebuild, we remove the damaged tile sections, repair the masonry, and drop the Gelco liner back into a sound flue. Skip the masonry fix and you’ll be back in three years with a lean.
- Crown and cap failure above a Gelco liner. The crown is the flat concrete slab on top of the chimney, and in Newark it cracks from freeze-thaw every few years. Water gets in, runs down between the clay tile and the Gelco liner, and rusts the liner from the outside in. A stainless liner will still rust if water sits against it. We rebuild the crown with a proper overhang and drip edge, then re-flash and re-cap. The Gelco liner usually doesn’t need replacing once the water stops.
Our Gelco Chimney Liner & Rebuild Process
Every Gelco job starts the same way: with eyes on the actual flue, not a guess from the ground.
- 1
You call (848) 331-2638. A live person answers. We schedule a time that works, and we’re there when we say we’ll be.
- 2
Camera inspection first. Wendell or one of his crew runs a camera down the flue before anything else. You see the footage. No exceptions.
- 3
A plain-English verdict. We tell you what’s failing, what can wait, and what it costs. The quote is written and it doesn’t change.
- 4
Parts decision together. If we’re replacing liner, we talk through Gelco OEM sections versus quality aftermarket that matches the diameter and alloy. If the aftermarket gets you the same service life for less, we say so.
- 5
The work. Liner pull, tile removal if needed, masonry repair, new liner dropped and connected, crown and cap rebuilt if that’s in the scope. We work clean and we tarp.
- 6
The test and the promise. Draft test, camera re-check, photos to you. Then the 90-Day Done Right Promise in writing: if it’s not right, one call brings us back at no charge.
What Gelco Chimney Liner & Rebuild Costs in Newark
Here are honest ranges for the Gelco work we do most often in Newark. These cover the common scenarios. Your house, your chimney, and your flue will set the final number, and you’ll know it before we start.
| Job Type | Typical Cost in Newark |
|---|---|
| Gelco liner section repair (splice or tee replacement) | $600 – $1,400 |
| Flexible liner replacement, single story | $2,200 – $3,800 |
| Flexible liner replacement, two to three story rowhouse | $3,500 – $4,800 |

| Full chimney rebuild with Gelco liner and new crown | $7,000 – $12,000 |
What moves the price: roof access and staging, how many flue tile sections need to come out, whether the crown and cap are part of the job, and the liner diameter your appliance needs. We don’t add a “Newark fee” and we don’t round up at the door. Call (848) 331-2638 for a free estimate, and bring us any written estimate from another shop for a second opinion at no charge.
Why Newark Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike founded Top Hat Chimney in 1999 and has been on Newark roofs since before half the liner trucks in town were franchises. He publishes his name and license number. He answers the phone himself half the time. And when we finish a Gelco job, the 90-Day Done Right Promise is stamped on the invoice in writing. One call brings us back.
We work with Gelco, DuraFlex, and HeatShield because flue problems don’t always stay in one brand’s lane. If your Gelco liner is shot and a DuraFlex section is the right call for the appliance run, we’ll tell you. If HeatShield resurfacing will save a chimney a full rebuild would cost twice as much to fix, that’s what we’ll quote. Background-checked crew, uniformed, with a real arrival window that we actually honor. And every job, every time: the camera footage and a plain-English verdict, no exceptions.
FAQs
We can’t process Gelco’s manufacturer warranty directly since we’re an independent Gelco service provider, but we’ll give you the documentation and photos you need to file a claim. Most Gelco liner warranties are pro-rated and require proof of annual cleaning, which is another reason to keep your sweep records straight. Call (848) 331-2638 and we’ll walk you through what your warranty actually covers.
We repair what’s repairable and replace what isn’t, and you’ll see the camera footage that justifies the call either way. A failed tee, a separated seam, or a short damaged section is usually a repair. If the liner is rusted through in multiple places or kinked beyond straightening, replacement is the honest answer. Nobody at Top Hat Chimney gets paid to sell you a liner you don’t need.
Common Gelco flex diameters and connectors are usually available within a few days from our supply chain. Custom lengths or odd sizes can take a week. But since we’re not tied to one manufacturer, we can often use a quality aftermarket liner with the same diameter and alloy spec and finish the job days sooner. Call (848) 331-2638 and we’ll give you a real timeline, not a phone promise.
Once a year, burn or no burn. Chimneys break in the off-season too. Newark’s freeze-thaw cycles crack crowns and let water in, and salt air from the port accelerates rust on anything metal. An annual camera inspection catches seam wear and tee pitting before they become a carbon monoxide problem. The inspection costs less than the liner that would follow if you skip it.
Three things, and none of them are cheap. First, the liner keeps degrading until it can’t contain the flue gases, which means carbon monoxide can seep into the house instead of up the flue. Second, moisture between the liner and the clay tile accelerates masonry damage, so a small repair becomes a partial rebuild. Third, your furnace or water heater starts drafting poorly, which shows up as higher gas bills and burner issues. The repair cost doesn’t go down by waiting. Call (848) 331-2638 for an estimate and we’ll tell you honestly whether it can wait a season or shouldn’t.
