Famco Flue Liner Replacement: The Clifton Owner’s Guide
A Famco flue liner replacement in Clifton typically runs $1,450 to $2,800 installed, depending on the liner diameter, length of the run, and whether the old liner needs to be extracted through a tight damper housing. We stock Famco-compatible stainless liners on the truck and can complete most swaps same day or next day once we’ve measured the flue. Most Clifton homeowners discover the problem the way you probably did: a Level 2 camera inspection showed a rust-through, a cracked seam, or a liner that’s delaminated so badly the exhaust gases are finding the masonry instead of the sky.
This page tells you exactly how we match the replacement to your Famco model, what it costs in Clifton, what fails first, and what the swap actually involves. The camera doesn’t guess. Neither do we.
Which Famco Models This Applies To
If your home was built or relined between roughly 1998 and today, chances are the flue liner running up your chimney is either Famco or a Famco-pattern equivalent. Famco liners are sold under a handful of product lines, including the FlexKing and SureFlex series, which cover both gas and oil applications. The gas liners are typically AL29-4C stainless, thin-walled, and engine-designed for a gas appliance’s lower flue temperature. The oil and wood liners are heavier 316L stainless, built to handle hotter, dirtier exhaust.
The fastest way to identify yours is to look at the tag attached where the liner exits the appliance at the thimble, or check the original installation paperwork from whenever the liner was dropped. No tag? The liner wall thickness and rib pattern usually tell us what we’re dealing with before we even step off the ladder. The compatibility gotcha in Clifton matters: replacing a gas-rated Famco with an off-brand liner built for an oil furnace is a mistake we see on older flips in the Botany Village and Delawanna sections. That’s not a direct swap. The liner must be rated for the fuel type and BTU load of the appliance already in your basement.
Level Two Chimney Clifton is an independent service provider, not affiliated with Famco. We stock Famco-compatible replacements and genuine Famco where the original spec calls for it. We also work with DuraFlex, HeatShield, and Gelco liners when a better match exists for the specific chimney.
Key Takeaways: Famco Flue Liner Replacement in Clifton
- Typical installed cost in Clifton: $1,450 to $2,800, with exact pricing written before work starts.
- Not all stainless is the same: a gas-rated liner is not a furnace or wood liner. The wrong rating is a real safety and code issue.
- What takes a liner out, in order: condensation corrosion, blocked flue overheating, then mechanical damage from a misaligned install.
- We stock replacements on the truck. Most jobs get done same day or next day, depending on length and diameter needed.
Signs Your Famco Flue Liner Replacement Is Failing

- Rust flakes falling into the cleanout at the base of the chimney. This is the classic tell on gas liners in Clifton. The acidic condensate produced by a high-efficiency gas appliance eats through AL29-4C alloy over ten to fifteen years. The flakes collect in the breaching and the cleanout. We see this most often in older Homes in the Richfield section where the original clay tile was never intended to handle a gas appliance’s moisture load.
- A sulfur smell in the basement, or a CO detector that goes off without an obvious source. Both mean exhaust is not fully exiting the flue. A delaminated liner seam or a rusted-through section lets flue gases bleed into the masonry and then into the living space. We treat this as urgent.
- Visible cracking or a separated seam on the liner section near the appliance connection. Thermal cycling on a liner clamped too tight or misaligned at the thimble causes fatigue right at the connection point. The failure is almost always visible there first.
- Water damage on the drywall chroming the chimney chase. A liner that’s failed lets moisture migrate through the masonry instead of out the top. You’ll smell the damp before you see it, and then the paint starts to bubble.
- The camera scan shows what you were told not to worry about. Most Clifton homeowners with a failed Famco liner were told by another company that “the liner looks fine” based on a flashlight look from the top. A camera pushed to the smoke chamber tells a different story. If we can see light through the liner wall or a seam that’s parted, the liner is done.

AfterReplacement Cost & What’s Included
Here’s the straight price range for a Famco flue liner replacement in Clifton. We quote in writing before any work starts, so these numbers won’t shift after a tech is already in your driveway.
| Liner Type | Clifton Installed Price Range | When It Applies |
|---|---|---|
| AL29-4C gas liner (single story) | $1,450 - $1,900 | Gas furnaces and water heaters, shorter flue runs |
| AL29-4C gas liner (two story) | $1,900 - $2,400 | Gas appliances with longer runs or offset flues |
| 316L liner for oil or wood (single story) | $1,750 - $2,300 | Oil furnaces, wood stoves, fireplaces |
| 316L liner for oil or wood (two story) | $2,300 - $2,800 | Longer runs, steeper offsets, or difficult access |
What drives the spread: the liner diameter (4″, 5″, or 6″ are the common Clifton sizes), whether the old liner has to be cut out in sections due to a narrow damper throat, and whether the chimney sits on the garage side or requires staging. Every quote includes the liner, connectors, termination cap, and top plate. Labor is included. The warranty is written on the quote: parts warranty from the liner manufacturer, and our 365-Day Done Right Promise stamped on every job under the Haven Standard.
DIY or Call Us?

You can safely check a few things yourself. At the cleanout, look for rust flakes. At the appliance, look at the liner connection for a cracked or slipped seam. Open the damper and shine a flashlight up the flue; if light shows through the liner wall, write down where. None of that is dangerous. What is dangerous is climbing onto a Clifton roof in January and attempting to extract a liner without a second person on the ground, a ladder rated for the load, and experience with how a liner binds inside a clay tile flue. Liners pinch at the offset. They tear at the top plate. They lose their shape the minute you’re halfway out, and now you’re on a steep pitch with a snake of stainless steel fighting you and no helper in sight.
Beyond the physical risk, most DIY liner replacements fail inspection because the liner wasn’t sized for the appliance BTU rating, or the termination cap wasn’t sealed correctly, or the clearance to combustibles was wrong. We run a camera down the finished flue before we call the job done. If it’s not right, we fix it now, not after six months of exhaust leakage. Call us at (551) 282-9640 and we’ll give you a written price before anyone picks up a tool.
FAQs
A gas-rated Famco liner in Clifton typically lasts 12 to 18 years, depending on the moisture load from the appliance and whether the liner was correctly sized. Clifton’s humid summers and cold winters accelerate the acidic condensation cycle that eats AL29-4C alloy, which is why we see more corrosion here than in drier climates. Oil and wood liners last longer, often 20 to 25 years, because the exhaust is hotter and drier.
Small pinhole pitting near the top can sometimes be addressed with a sealant patch, but we won’t recommend it on a liner older than ten years. The issue is that liner corrosion is almost never isolated; if you found one pinhole, the alloy is thin everywhere and another hole is already forming. We’ll tell you plainly when a liner can wait. When we say replace, we’ll show you the camera footage so you see what we see.
Most Famco liner replacements in Clifton take three to five hours from setup to final camera verification. That includes removing the old liner, dropping the new one, reconnecting at the appliance, sealing the top, and running a full camera scan to confirm the liner is seated correctly from top to bottom. If we’re also replacing the termination cap or adding a top plate, budget another 30 minutes.
We stock the common diameters and lengths on the truck, including 4-inch, 5-inch, and 6-inch for gas and oil applications. If your run needs an unusual length or a custom offset, we’ll have the liner in by the next morning. Either way, you’ll get a written price and a written scope before the liner leaves the truck. Call (551) 282-9640 and we’ll size it up over the phone, then confirm in person with the camera.
