Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Ellicott City Owner’s Guide

We stock Famco-compatible flue liners on our trucks and install them throughout Ellicott City, with most single-story replacements running $2,400 to $3,800 installed and two-story jobs typically landing between $3,200 and $4,900. We can usually complete the swap in a single day once the old liner is out and measured. Most Ellicott City homeowners discover the problem the same way: a sweep or camera inspection finds a crack, a gap at a joint, or a liner section that has separated after years of heating-season expansion and contraction specific to Maryland’s freeze-thaw cycles.

Level Two Chimney Ellicott City is an independent service provider, not a Famco dealer or affiliate. We install and service Famco products because they’re well-built, but we’re not bound to any manufacturer’s sales targets, which means we tell you when a liner genuinely needs replacement and when it doesn’t.

Which Famco Models This Applies To

Famco manufactures flexible stainless steel chimney liners in several grades and diameters, and the replacement path depends on which product line you have. The most common liners we encounter in Ellicott City homes are Famco’s 316L stainless steel flexible liners, typically 5.5-inch or 6-inch diameter for masonry fireplaces and wood stoves, and their 316Ti alloy for higher-temperature applications. Famco also produces rigid stainless sections used in some retrofit jobs.

The compatibility gotcha is the wall thickness and alloy, not the brand name stamped on the label. A 6-inch Famco liner won’t match a 6-inch liner from another manufacturer if the gauge differs, because the connector fittings and termination caps are sized to the specific wall thickness. When we inspect a failing Famco liner, we check the original gauge (usually .005 or .006 for flexible liners) against what we’ll install so the top plate, rain cap, and appliance connector all seat properly. If the original label is gone, we measure the inner diameter and inspect the seam pattern to identify the exact product.

For Famco owners, the OEM-versus-aftermarket decision is straightforward: we install genuine Famco replacements when the chimney originally had a Famco system and nothing has changed. When conditions have changed (a new appliance, a different fuel type, or altered flue dimensions), we’ll recommend a different brand like DuraFlex, HeatShield, or Gelco if it’s a better match, and we’ll tell you why. We don’t upcharge parts as a revenue line. The liner cost is on the written estimate, separated from the labor, and it’s the same price we pay through the Haven buying network.

Signs Your Famco Flue Liner Replacement Is Failing

• Flakes of shiny metal in the firebox or cleanout. This is pieces of the liner’s inner wall delaminating, common after 12 to 18 years in Maryland homes where humid summers cause condensation inside the flue that corrodes stainless from the inside out.
• A visible gap or separation at a liner joint seen on camera. Flexible liners are joined in sections, and thermal cycling in Ellicott City (hot fires followed by cold nights) eventually loosens those joints. A separated joint lets flue gases escape into the chimney cavity and sends carbon monoxide into wall voids.
• Water staining on the ceiling or walls near the chimney chase. A cracked liner lets moisture through, and the chase becomes a slow drip system. We see this in Ellicott City after wet winters, especially in the older stone-foundation homes near Historic Main Street where the chimney chase was never insulated.
• A smell of smoke in rooms adjacent to the chimney, even when the fireplace isn’t in use. Flue gases are finding a path through the liner wall or a failed joint into the house, not up the flue.
• Your sweep reports Class III creosote buildup despite regular cleanings. A damaged liner’s rough, corroded surface holds creosote that a good liner would shed. Class III is the hard, glossy glaze that’s the most difficult to remove and the most likely to ignite.

Here’s the part most homeowners don’t hear until it’s their chimney: a failed flue liner is not a maintenance issue, it’s a containment failure. The liner exists so that heat, sparks, and combustion gases stay inside a sealed channel. When it fails, the fire is now using the chimney structure itself as its flue, and that structure is not built for it.

Replacement Cost & What’s Included

Installed Famco-compatible flue liner replacement in Ellicott City runs from $2,700 to $4,900 for most homes, and the gap comes down to three things: how many stories the chimney runs, whether the old liner comes out in one piece or has to be cut out in sections, and whether the existing top plate and cap can be reused or need replacement. We write the exact number before any work begins. No ‘call for a quote.’ The written estimate lists the liner cost, the labor, and any additional parts (top plate, cap, connector) as separate lines.

Every replacement includes a camera inspection before and after, a full photo record of the new liner in place, and our written warranty on the work. Under Clause 4 of the Haven Standard, you get the camera footage, the still photos, and the written scope. If you want to see the old liner after we pull it, we’ll leave it in the driveway and point to the exact crack or joint failure that made replacement necessary. We’ve operated this way since 2009 and it’s never once made a bad liner look better than it was.

DIY or Call Us?

There is no safe version of this as a weekend job. A flue liner replacement involves working at height, cutting stainless steel, and handling sections of liner that must be connected and sealed correctly or you’ve made the chimney more dangerous than when you started. We recommend against any homeowner attempting it, full stop.

What you can safely do is look at the liner from the bottom with a flashlight and take a phone photo. Look for obvious gaps at joints, rust trails, or shiny flakes in the cleanout. Then call (443) 363-5262. One of our background-checked technicians will camera-scan the liner, show you the footage on the spot, and give you a written price before leaving. Corrine Halstead has run crews across Howard County for the better part of a decade, and her rule is the same on every job: the camera comes back up before a single number gets written down. The camera doesn’t soften what it finds, and neither do we.
