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 Peabody: What to Know First
We handle Gelco chimney liner replacement and partial or full rebuilds in Peabody weekly, and most jobs are wrapped up in a single day once the new liner is on hand. A typical Gelco stainless liner replacement around here runs between $2,800 and $5,400 depending on flue height, roof pitch, and whether the crown or top plate needs work too. We’re an independent Gelco service provider, not a factory shop, so the price you get on the phone is the price on the invoice. This page is for Peabody homeowners with a Gelco liner that’s pitted, separated, leaking, or just old enough to be questionable. Call Wendell and his crew at (978) 637-8560 and we’ll take a look.
How Gelco Products Fail - and How We Fix Them
Gelco makes a solid liner. That doesn’t mean it lasts forever, and in Peabody weather it doesn’t have to. Here’s what we actually see when we open one up:
- Teardrop distortion on the ovalized section. Gelco’s oval-to-round flex liners, particularly the older smooth-wall 316Ti runs installed before 2015, tend to crush slightly where the flue passes through the clay tile offset at the smoke shelf. Homeowners notice it as a whistle when the wind hits a certain way, or a fireplace that drafts fine until a fire gets hot. That kink is a laminar-flow killer. We pull the section, ovalize a new length properly with the hand-crank die, and usually fix the draft for good.
- Pinhole corrosion at the weld seam on flexible Gelco liners. Gelco’s flex liner is welded in a continuous spiral seam. In coastal Peabody air, we see chloride pitting along that seam on liners that vent natural gas or oil appliances, especially if the water heater and furnace share a flue. The fix is section replacement if the pitting is localized, or a full re-line if it’s more than a few feet. We’ll show you the camera footage before we quote anything.
- Separated rivets on the top plate. The Gelco top plate is a good design, but the pop rivets they shipped with in the early 2000s don’t love temperature swings. After enough freeze-thaw cycles in a Peabody winter, the flashing separates from the plate and water starts working its way down. That’s a half-day fix: new plate, stainless rivets, fresh sealant, done.
- Cracked insulation wrap on the outside-mount Gelco liners. If you have an exterior chimney and an older insulated Gelco liner, the wrap tends to wick moisture right at the point where it meets the tee at the cleanout. Once the insulation is waterlogged, the liner underneath runs colder and creosote builds faster. We strip it, inspect the liner itself, and often find the liner is fine. The wrap gets replaced, not the whole system.
- Glazed creosote hiding a scarred liner. A Gelco liner that’s been hot-fired for years can look fine from the top down and be scarred to the metal inside, especially if the homeowner burns a lot of pine or green wood. The glaze holds everything in place until it doesn’t. When we sweep and the brush hangs up on rough spots, that’s usually a liner that’s lost its smoothness. A new Gelco 316Ti or a comparable DuraFlex liner brings it back.
Our Gelco Chimney Liner & Rebuild Process
Here’s how a Gelco liner job goes from the first phone call to the last brush stroke:
- 1
Call and talk to a person. You call (978) 637-8560, Wendell or someone from the crew picks up, and we set a window that works. No call center, no “please hold.”
- 2
Camera first, always. Before we recommend a single dollar of work, we run a camera down the flue and look at the whole path. You see the footage with us. If the liner is fine, we say so and tell you to burn safely. If it’s not, you’ll see exactly why.
- 3
The parts decision. For Gelco liners, we compare OEM Gelco replacement sections against DuraFlex and HeatShield equivalents. If a Gelco part is available and priced reasonably, we use it. If a quality aftermarket section is the better move for your flue and your wallet, we’ll tell you that too, in plain English.
- 4
The work itself. We pull the old section or full liner, prep the flue, install the new liner, and make sure it’s secure from the crown to the cleanout. No shortcuts on the termination, no silicone where stainless and a clamp belong.
- 5
Test and show you. We run the camera again after the install so you can see the new liner from inside, then we light a small test fire or check draft with a smoke pencil. You watch it pull.
- 6
The 90-Day Done Right Promise. Every Gelco liner or rebuild job leaves with our promise in writing: if it’s not right, one call brings the crew back at no charge. That’s the whole point of hiring a chimney company with a name on the truck.
What Gelco Chimney Liner & Rebuild Costs in Peabody
Here’s the straight answer, because you shouldn’t have to guess before you pick up the phone:
- Liner repair (patch, section, seal): $350-$950 depending on access and damage.
- Single-story flexible Gelco liner replacement (gas or oil): $2,200-$3,400.
- Two-story flexible Gelco liner replacement with top plate and cap: $3,200-$5,100.
- Partial rebuild (top 3-5 courses of brick, crown, wash): $1,800-$3,500.
- Full chimney rebuild from the roofline up: $5,500-$12,000 depending on height, access, and masonry condition.
What moves the number is flue height, roof pitch (some Peabody rooflines demand staging and a spotter), whether the existing crown gets saved, and what the camera shows inside. We’ll give you the quote before anything starts, and it won’t change when the truck pulls away. Call (978) 637-8560 for a number that’s tied to your actual flue.
Why Peabody Homeowners Call Top Hat Chimney for Gelco Work
We’ve been working chimneys in Peabody since 1999, and the West End alone has kept Wendell Pike busy for most of that time. Homeowners here have learned there’s a difference between a company that sends a stranger with a clipboard and a sweep who remembers where your flue runs because he’s been in it before. We know Gelco’s quirks because we’ve pulled and rebuilt enough of them to know what holds up and what doesn’t. When a Gelco liner is past saving, we’ll tell you. When a DuraFlex or HeatShield liner is the smarter choice for your appliance and your chimney’s height, we’ll tell you that too. The point isn’t to sell you a brand. It’s to get the smoke out of the house and the water out of the masonry. And if it doesn’t need doing, Wendell will tell you that too.
FAQs
Gelco’s warranty typically covers manufacturing defects in the liner itself, but it generally doesn’t cover labor, insulation, top plates, or damage from creosote, chimney fires, or installation that wasn’t done to spec. We can help you document a warranty claim with photos and camera footage, and we’ll give you a straight read on whether the claim is likely to stick. Call (978) 637-8560 and we’ll walk it through with you.
It depends on what the camera shows. Localized pitting, a bad top plate, or a separated seam can often be repaired. Full-length corrosion, a crushed oval section, or glazed creosote over a scarred liner usually means replacement is the honest call. We won’t recommend a replacement until we can show you the footage that justifies it. Free estimates at (978) 637-8560.
A properly installed 316Ti stainless liner in a well-maintained chimney here typically lasts 20 to 30 years. Coastal air, wet seasons, and frequent hot fires will shorten that. Annual sweeping plus a quick inspection every year is the best way to get the full life out of it. Call us and we’ll put you on a schedule that fits your burn pattern.
That’s more common in Peabody than people expect. The brick and mortar above the roofline take the weather, while the liner inside stays dry and intact. When the masonry is spalling or the crown is cracked, we’ll rebuild what’s necessary from the roofline up and leave the liner alone if it’s sound. That kind of honesty saves you money, and it’s how we’ve kept customers for 29 years.
Yes, and it happens regularly. We’re an independent Gelco service provider, so we don’t have a stake in defending another shop’s work. We’ll document the problem with camera footage, explain what should have been done, and give you a quote to make it right. (978) 637-8560 gets you straight to a live person.
