Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Fairfax Owner’s Guide

Famco flue liner replacement in Fairfax typically runs $1,800 to $3,400 installed, depending on the liner diameter, length of the run, and whether the old liner fights us on the way out. We stock Famco-compatible stainless steel liners and fittings on the truck, so most replacements in Fairfax can be done in a single visit. The way most Fairfax homeowners discover the liner has failed is not dramatic: rust flakes in the firebox, a faint smoky smell that lingers after a fire, or a chimney sweep showing them camera footage of a seam that has pulled apart. If you are reading this, chances are you already know which part failed. The question now is getting the right replacement matched to your setup, priced honestly, and installed without a second surprise invoice.

We are an independent chimney service in Fairfax, not a Famco dealer or affiliate. That matters because we can be straight with you about when a Famco liner can be saved and when it genuinely needs to come out. Wendell Pike and his crew have been pulling old liners out of Fairfax chimneys long enough to know the difference.

Which Famco Models This Applies To

Famco has made flue liners and venting components for a long time, and the brand shows up in a lot of Fairfax homes built through the 80s, 90s, and early 2000s. The replacement path depends on what you have. Rigid stainless steel Famco liners, usually 316L alloy, were common in new construction. The flexible Famco liners, often a 316Ti alloy, tend to show up in retrofits done when older masonry chimneys were brought up to code. Both fail differently, and the fix is not always identical.

The first thing to look for is the label. Famco stamps product info on the liner itself or on a tag at the connection point near the appliance. You may see a series name like Famco Flex or Famco rigid pipe, plus a diameter callout: 4-inch, 5-inch, 6-inch, 7-inch, or 8-inch are the sizes we see most in Fairfax. If the label is gone, which happens often after years of heat cycling, we measure the inner diameter with a caliper and check the wall thickness. Getting the diameter wrong by even a half inch means the liner will not seat properly at the appliance collar, and you will be back to square one.

On the OEM versus aftermarket question: Famco liners have not always stayed in continuous production across every series, and some sizes are only available today through aftermarket equivalents. The good aftermarket liners, the ones we carry, meet or exceed the UL 1777 listing that Famco liners were originally certified under. That listing matters for your homeowner’s insurance and for any Fairfax County inspection down the road. We will tell you plainly if an aftermarket liner is the only viable option for your diameter and what that means for the install. No jargon, no upsell.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or metal fragments falling into the firebox. This is the one we see most in Fairfax. Condensation and years of combustion acids eat at the liner wall from the inside until it starts shedding. Once you see flakes, the wall is thin enough to worry about.
• A campfire smell that lingers in the room after the fire is out. That smell often means the liner has a crack or separated seam, and smoke is finding its way into the chimney chase instead of going up and out. It can also mean the liner has pulled away at the appliance connection.
• Visible warping or discoloration near the appliance collar. High heat concentrates right at the connection point. Discolored blue or black metal there is a sign the liner has taken more heat than it was built for, and the temper of the steel is compromised.
• Draft problems that were not there before. A liner that has buckled, collapsed slightly, or separated will not pull the way it used to. If your fires are suddenly lazy, smoky on startup, or hard to keep lit, the liner is a prime suspect.
• Water staining on the ceiling or wall near the chimney chase. A failed liner lets flue gases condense inside the chase, and that moisture bleeds into surrounding framing. You may also get a musty smell in the room when the fireplace is not in use.

Any one of these is worth a camera inspection. In Fairfax, where cold winters and humid summers stress chimney systems year-round, a liner that is flaking rust has usually been failing for a while before you notice it.

Replacement Cost & What’s Included

For Famco flue liner replacement in Fairfax, plan on $1,800 to $3,400 installed. The spread comes from three things: liner diameter and length, whether the old liner needs to be cut out in sections or comes out in one pull, and whether we find collateral damage at the crown or appliance connection once we get in there. A short 6-inch flexible liner in a single-story Fairfax rancher sits at the low end. A tall two-story run with an 8-inch rigid Famco liner that has rust-welded itself to the thimble sits at the high end.

Here is the honest price structure:

• Liner material: $800 to $1,700 depending on diameter, length, and flex versus rigid.
• Labor and removal of the old liner: $700 to $1,200. Removal is where the surprises live, and we will show you what we find.
• Connection fittings, top plate, and rain cap: $200 to $400. These are replaced as a set because reusing old fittings on a new liner is how you end up doing the job twice.
• Camera inspection after install: included. We do not charge extra to prove the job was done right.

No-hassle upfront pricing means the number you hear on the phone is the number on the invoice. If the old liner fights us and adds an hour of labor, that is our problem, not a line item on your bill. Every job gets the 90-Day Done Right Promise in writing, plus the standard $40 off any repair over $200, and 10% off for seniors and veterans.

DIY or Call Us?

Let’s be straight about what you can safely check yourself and where this job goes wrong for a homeowner. Standing in your living room, you can look for rust flakes in the firebox, run a flashlight up the first few feet of the liner from the appliance connection, and note any new water staining on the ceiling near the chase. That is useful information and it helps us quote the job over the phone.

What we do not recommend is pulling the liner yourself. A Famco liner runs the full height of the chimney, often through tight offsets and around framing you cannot see. Mid-pull, a corroded section can break apart and drop. If the liner is connected to a gas appliance, you are also dealing with venting that carries carbon monoxide. That is a job for someone with the right equipment and more than a little practice. We have been doing this in Fairfax for over 29 years, and Wendell and his crew still learn something new from the odd chimneys around the Government Center area. If it does not need doing, we will tell you that too. Call (571) 624-2385 for a free estimate, and we will bring the camera.
