Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Newark Owner’s Guide

If your Famco flue liner has cracked, warped, or rusted through, replacement in Newark typically runs $2,200 to $4,800 installed, depending on liner diameter, length, and whether your chimney needs a full teardown or can accept a pull-through liner. We stock Famco-compatible stainless steel liners on the truck and can usually complete the swap in a single visit. Most Newark homeowners discover the problem the hard way: water staining on the ceiling near the chimney, a smoky smell that won’t quit, or the sweep who shows up for an annual cleaning puts a camera up there and shows you exactly where the liner has given out.

Call (848) 331-2638

You’re not alone if you didn’t know your Famco liner was failing. It’s hidden inside the flue, and it doesn’t announce itself until something visible goes wrong. The good news is that a liner replacement is a known job for us, and we can have your chimney venting safely again without drama.

Key Takeaways

• Famco liners most often fail at the seam welds and the first three feet above the appliance connector, where heat stress is highest.
• We carry 316L stainless steel liners in the diameters Famco systems commonly use, plus the connectors and top plates to match.
• Every replacement includes a camera inspection before and after, so you see the old liner’s damage and the new liner in place.
• Our 90-Day Done Right Promise covers the work in writing. If it’s not right, one call brings Wendell and the crew back.

Which Famco Models This Applies To

Famco has manufactured flue liners and venting components for decades, and the liners we replace most often in Newark come from their older 300-series and 400-series stainless steel lines, along with a fair number of the galvanized liners that went into mid-century rowhouses and post-war ranches. If you have a Famco liner, you’ll usually find the model information stamped into the metal near the appliance connection or on a tag attached to the liner where it exits the chimney. Sometimes that tag is long gone, and that’s fine. We measure the inside diameter and overall length on site, and match the replacement accordingly.

Here’s the compatibility gotcha that catches a lot of owners off guard: Famco’s 300-series liners used a different lock seam profile than their 400-series, which means an aftermarket liner that says it’s “universal” doesn’t always seat correctly where the Famco connector meets the appliance collar. We’ve fixed enough of those mismatches to know exactly which aftermarket profiles actually work with Famco connectors and which ones leave a gap that lets carbon monoxide into the chase. For most Newark homes, an OEM Famco liner or a 316L equivalent with the correct seam profile is the right call.

One more thing worth knowing: Famco liners from the 1960s and 1970s were often single-wall galvanized. Galvanized does not hold up to the combustion byproducts of a gas or oil appliance over decades. It rusts from the inside out. When we pull one, it’s not unusual for it to come out in pieces. The replacement should always be stainless, and we’ll tell you that plainly before any work starts.

Signs Your Famco Flue Liner Replacement Is Failing

Here are the symptoms we see most often in Newark homes when a Famco liner needs replacement:

• Water or brown stains on the ceiling or wall near the chimney. A pinhole in a liner lets condensation escape into the surrounding masonry or chase. By the time you see the stain, the liner has been leaking for a while.
• A smell like wet ash or old smoke that gets stronger when the furnace or boiler kicks on. That’s exhaust finding its way back into the house through gaps in the liner. It should be going up and out, not into your living room.
• Visible rust flakes or metal debris at the base of the chimney cleanout. Galvanized Famco liners shed rust as they fail. If you open the cleanout door and see what looks like red cornflakes, the liner is actively deteriorating.
• A chimney inspection report that shows cracks, gaps, or a corroded seam. We photograph everything with a camera, and we’ll show you the footage. If the liner is cracked, patching it is not a repair; it’s a delay.
• The appliance has been struggling to draft properly. A water heater or furnace that has started backdrafting, setting off carbon monoxide detectors, or burning with a lazy yellow flame may be fighting a compromised liner. This is the one that gets our full attention right away.

If you’re seeing any of these, call us before you run the appliance again. A failed liner is how carbon monoxide ends up back inside your house, and that’s a problem that doesn’t announce itself. We’ll schedule a camera inspection and tell you exactly what’s going on up there.

Replacement Cost & What’s Included

For a typical Newark single-family home, here’s what we see for Famco flue liner replacement:

• Straight pull-through stainless liner, single story: $2,200 - $2,800
• Straight pull-through stainless liner, two-story: $2,600 - $3,400
• Replacement with connector, top plate, and cap (common from Newark winters): $3,000 - $4,000
• Full rebuild when the existing liner is too far gone to pull through: $3,800 - $4,800

What drives the difference in Newark specifically: liner diameter (4-inch is common for water heaters, 6- and 7-inch for furnaces), chimney height, whether we can access the flue from the roof or need to work from inside, and whether the surrounding masonry is in good enough shape to accept a new liner without additional repairs. Every quote includes the liner, connectors, top plate, cap where needed, and the labor to install and test it.

You’ll hear one number on the phone, and that’s the number on the invoice. No add-ons after the fact. Every replacement also carries our 90-Day Done Right Promise in writing, and we walk you through the camera footage before and after so you know exactly what you paid for.

DIY or Call Us?

We’re honest about this because it matters: replacing a flue liner is not a weekend project, and it’s not something a homeowner should attempt. You’re working at height, often on a roof in weather that doesn’t forgive mistakes, and a liner that isn’t seated correctly can send exhaust into the house instead of up the chimney. Carbon monoxide is invisible and has no smell. That’s not a risk worth taking to save a few hundred dollars.

What you can do safely is check the cleanout door for rust debris, look for water stains near the chimney, and note any new smells when the furnace or water heater runs. If any of those show up, call us at (848) 331-2638. Wendell and his crew will put a camera up there, show you what we found, and tell you straight if the liner needs replacing or if it can wait. If it needs doing, we’ll do it. If it doesn’t, I’ll tell you that instead.
