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.

AfterGelco Chimney Liner & Rebuild in Jamesburg: What to Know First
We provide independent Gelco chimney liner repair and rebuild in Jamesburg, and most jobs are completed within one to three days once we’ve seen the flue on camera. An honest number for liner work in this area runs $850 to $4,200 depending on length, access, and whether the existing Gelco crown and firebox are sound. If you own a Gelco system and the liner is acting up, call (609) 905-5820 and Wendell Pike will give you a straight answer about whether it needs fixing now or can wait another season.
This page is for Jamesburg homeowners with Gelco liners or chimneys showing cracking, spalling, flue gas smells, or liner collapse. We work on these systems every month, and we know what holds up in central Jersey weather and what doesn’t.
How Gelco Products Fail - and How We Fix Them
Gelco builds a decent chimney, but the liners and crowns fail in predictable ways. Here’s what we actually see on Jamesburg roofs:
- Gelco stainless liners with corroded seams. The Gelco rigid stainless liners we pull from older Jamesburg chimneys often show corrosion at the seam welds first, not the pipe body. Condensation from high-efficiency furnaces venting through an oversized flue sits in those seams. The fix is a correctly sized replacement, and when the old Gelco liner is done, we say so instead of patching it.
- Gelco flexible liner kinking at the smoke shelf. Gelco flex liners installed twenty-plus years ago in Jamesburg homes frequently kink right where they enter the smoke chamber. They were often undersized for the appliance, and that kink becomes a creosote trap. We pull them, inspect the smoke shelf, and install a properly sized flex or rigid liner with a clean sweep path.
- Cracked Gelco crown with liner exposure. Gelco crowns poured thin years ago crack in New Jersey freeze-thaw cycles. Once water gets between the crown and liner, the liner’s exterior corrodes even if the interior looks fine. We rebuild the crown with a proper overhang and drip edge, then set the new liner so water can’t find that seam again.
- Gelco liner sections separated at the flue offset. Chimneys that jog through an attic or around a beam put stress on sectional liners at the offset. Gelco liner joints can separate there, especially in older Jamesburg homes with shallow offsets. We sleeve or rebuild that section rather than condemning the whole flue when the rest is solid.
- Gelco chimney with a crumbling brick shoulder supporting the liner. The liner is only as good as the masonry holding it. In neighborhoods like Victory Park, we regularly see brick shoulders that have absorbed decades of moisture and no longer hold the liner plumb. When that’s the case, a liner swap alone won’t fix the problem. We do a partial rebuild, reset the liner, and you get a chimney that actually breathes.
Our Gelco Chimney Liner & Rebuild Process
Here’s how a Gelco liner and rebuild job goes when you call Top Hat Chimney:
- 1
We schedule the visit and show up when we say we will. If we’re running late, you get a call. No call center, no four-hour window.
- 2
Camera inspection first. We run a camera down the flue after a visual check from the roof. You see the footage and get a plain-English verdict. If the Gelco liner doesn’t need replacing, you’ll hear that from us, not a sales pitch.
- 3
Parts decision. When a Gelco liner needs work, we look at OEM against proven aftermarket liners that fit the existing system correctly. Some Gelco parts are worth sourcing. Others, a quality flexible or rigid stainless liner from DuraFlex does the job better and doesn’t fight the existing masonry.
- 4
The repair or rebuild itself. We remove the damaged Gelco liner, address whatever caused the failure (crown, offset, brick shoulder, moisture entry), and install the new liner so it’s plumb, correctly sized, and swept clean.
- 5
Draft test and cleanup. After the liner is in, we test draft with the appliance running when possible. Then we clean up. Drop cloths go down before a single tool comes off the truck, and they come up when we leave.
- 6
90-Day Done Right Promise. If something isn’t right, one call brings Wendell and his crew back. In writing, on every job.
What Gelco Chimney Liner & Rebuild Costs in Jamesburg
Ballpark numbers for Gelco work in Jamesburg, based on what we’ve quoted and completed:
- Gelco liner inspection with camera: $150 to $250, credited toward repair if you proceed.
- Stainless liner replacement, straightforward access: $850 to $1,600 for a typical single-story Jamesburg flue.
- Flexible liner install with crown repair: $1,400 to $2,800 when the crown needs rebuilding at the same time.
- Partial rebuild (smoke chamber or shoulder) plus liner: $2,200 to $4,200 depending on brick access and material matching.
- Full Gelco chimney rebuild from the roofline up: $4,000 to $8,000. That’s the real number when the structure has spalled beyond repair.
What moves the price is access, liner length, how much masonry has to come out, and whether you need a custom crown. We price it before any tool touches brick, and that number is the invoice number. Call (609) 905-5820 for a free estimate.
Why Jamesburg Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike has been working chimneys in this part of New Jersey since 1999, and his name and license number are on the work. When a Jamesburg homeowner gets a Gelco quote from a national outfit, the price tends to change once the technician is on site. That doesn’t happen here. The price is set before the truck door opens, and the 90-Day Done Right Promise is in writing.
We don’t push Gelco parts when a DuraFlex or HeatShield liner is the better fit for the flue and the appliance. We carry and install all three, so the decision is based on your chimney, not our inventory. And when you call at 6 a.m. or 11 p.m., a live person answers. It might be Wendell himself.
Jamesburg homeowners also get the standing offers we’ve never taken down: $40 off any repair over $200, a free second opinion on any competing written estimate, no trip charge inside our service county, and 10% off always for seniors and veterans.
FAQs
We’re an independent Gelco service provider, not an authorized dealer, so any Gelco manufacturer warranty terms stay between you and Gelco. What we stand behind is our own work: the 90-Day Done Right Promise in writing, regardless of whose liner goes in.
Sometimes yes, when the damage is isolated to a joint or a short section and the rest of the liner is sound. We’ll show you the camera footage and tell you if a partial repair is worth doing or if you’re throwing money at a liner that’s near the end anyway.
Most liner replacements in Jamesburg are done one to three days after we’ve inspected and quoted, assuming we don’t find masonry that needs rebuilding first. Seasonal demand in October and November can add a few days. Call (609) 905-5820 and we’ll give you a real date.
A flue gas smell with a visually intact liner usually means a separated joint, a cracked crown letting pressure escape, or a negative-pressure issue in the house. We start with a camera and a draft test, because guessing at that problem is how you waste money. If it’s not the liner, we’ll tell you that too.
Spalling brick at the top of the chimney is often a crown problem, not a full rebuild. If the brick below is solid and the shoulders are holding, we can rebuild the crown and replace the liner. If the spalling runs deep into the stack, a partial or full rebuild is the honest fix. We’ll show you exactly what we’re seeing before you spend a dollar.
