Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Alexandria Owner’s Guide

If you have a Famco flue liner that’s cracked, rusted through, or delaminating, we stock and install Famco-compatible replacement liners throughout Alexandria, and the installed cost typically runs $1,850 to $3,400 depending on liner diameter, length, and whether you have a straight run or offsets. We can usually have your liner swapped within five to seven business days of the inspection. Most Alexandria homeowners discover the problem the hard way: they see flaking metal in the firebox, notice a rust stain on the ceiling near the chimney chase, or a home inspector flags the liner during a pre-sale check. If you’re seeing any of that, you’re in the right place.

Here’s what you need to know about Famco flue liner replacement in Alexandria, written by someone who has pulled more of these out than he cares to count.

Which Famco Models This Applies To

Famco has been building venting products for decades, and the liner line most Alexandria homes have is their stainless steel flex liner, commonly sold in 4-inch through 8-inch diameters. The Famco part number usually tells the story: if you can still read the label on the liner or the box it came in, you’ll see something like the diameter followed by the length and a UL listing. If you can’t read the label, we measure it. The outside diameter tells us what we’re working with, and the condition of the corrugations tells us whether we’re matching an OEM Famco liner or dropping in a quality equivalent.

One thing worth knowing: Famco liners were often sold as part of a complete kit, so the liner itself may not have a separate Famco stamp. It might be the cap, the top plate, or the connector that says Famco. We match the liner to the existing appliance connector size and the flue tile ID. We are an independent chimney company in Alexandria, not a Famco dealer, so we’ll tell you straight when a genuine Famco part matters and when a UL-listed 316L stainless equivalent does the same job for less money. In our experience, if your Famco liner ran for fifteen or twenty years, an equivalent 316L liner will do the same.

Signs Your Famco Flue Liner Replacement Is Failing

Liners don’t usually fail all at once. They fail in stages, and the signs are there if you know what to look for. The flue doesn’t care how the fire looks. It cares how it breathes.

• Flaking metal in the firebox or cleanout. That’s the inner wall of the liner shedding. Once the stainless starts to flake, the protective layer is gone and the pitting accelerates. We see this most often in liners that have been running damp wood or venting a gas appliance with no rain cap.
• Rust stains on the ceiling or wall near the chimney chase. Condensation inside a failing liner finds its way out. By the time you see the stain, the liner has been leaking flue gases into the chase for a while. In Alexandria’s humid summers, this shows up faster because the temperature swing between the hot liner and the cool chase creates more condensate.
• A smell you can’t place, like wet ash or sulfur, even when there’s no fire going. That’s creosote or combustion byproduct wicking back through a perforated liner. It gets worse in the shoulder seasons when the house is sealed up and the chimney isn’t drawing.
• Your CO detector nudges or reads low levels near the fireplace or mechanical room. A liner with pinholes can’t hold the draft, so combustion gases linger instead of venting. If you’re getting intermittent low-level CO readings and the furnace or fireplace shares that flue path, the liner is the first thing we check.
• The liner visibly sags, separates, or you can see light through it with a flashlight. In older Famco installations around Alexandria, particularly in rowhouses with an offset, the liner can pull apart at a seam. Once it separates, you’re venting into the chase. That’s a stop-using-it-now situation.

If any of this sounds familiar, call (571) 521-4837 and we’ll put a camera up there. The camera footage and a plain-English verdict, every time, no exceptions.

Replacement Cost & What’s Included

In Alexandria, a full Famco flue liner replacement on a standard one-story or two-story chimney runs between $1,850 and $3,400 installed. That’s the range because no two chimneys are the same: the diameter, the length, whether there’s an offset in the flue, and whether we’re also replacing the cap, top plate, or connector all move the number. A straight 25-foot 6-inch liner is on the lower end. A 35-foot 8-inch liner with an offset and a deteriorated cap is on the higher end.

Every quote includes the liner, the top plate, the cap, the connector, full installation, and a camera inspection before and after so you can see exactly what went in. We price the job before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice. And like every job we do in Alexandria, it’s backed by our 90-Day Done Right Promise: if it’s not done right, one call brings Wendell and his crew back at no charge.

We also run standing offers that apply to liner work: $40 off any repair over $200, a free second opinion on any written estimate, and 10% off for seniors and veterans, always. No fine print, no gimmicks.

DIY or Call Us?

You can check a few things yourself: look for flaking metal in the firebox, check for rust stains around the chase, and shine a flashlight up from the cleanout to see if the liner is visibly separated. That’s a smart homeowner diagnostic, and it tells us what we’re walking into before we arrive.

But pulling and replacing a flue liner is not a Saturday project. It means working on a roof, handling a multi-section stainless assembly, and knowing how to secure and seal the top plate so it holds through an Alexandria winter. A liner that’s installed wrong doesn’t just leak, it can separate at a seam inside the flue where you can’t see it, and that’s how carbon monoxide ends up in the house. This is one of those jobs where the cost of the professional isn’t the expensive part, the cost of the mistake is. Wendell Pike has been doing this work in the Alexandria area for going on two decades, and he’d rather tell you a liner can wait than sell you one that doesn’t need replacing. If it doesn’t need doing, he’ll tell you.

If the liner is done, get it done right. Call (571) 521-4837 and we’ll get you on the schedule.
