Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Hempstead Owner’s Guide

A Famco flue liner replacement in Hempstead typically runs $1,800 to $3,400 installed, depending on liner length, diameter, and whether we’re also replacing the connector pipe or rain cap. We keep common Famco-compatible liner sizes on the truck, so most Hempstead jobs go from inspection to finished install in a single visit. The way most owners find out a liner has failed: a chimney sweep flags it during an inspection, usually after a decade or more of Nassau County winters eating away at the stainless from the inside out, or when rust flakes start showing up on the fireplace floor.

Which Famco Models This Applies To

Famco built their name on furnace and boiler flue components before expanding into chimney liners, and their liner systems show up most often in Hempstead homes with mid-century oil-to-gas conversions or standalone furnace flues. The liner part number is usually stamped on the original cap or readable on a tag near the appliance connection. What matters for replacement: interior diameter (common sizes run 5, 6, 7, and 8 inch), wall thickness, and whether the original was a single-wall or double-wall insulated liner. If your old liner is a bare single-wall running through an exterior chimney, that’s often the root cause of the failure in the first place.

We’re an independent Hempstead contractor; we’re not affiliated with Famco. When we replace a Famco liner, we typically install a UL-listed 316L or better stainless flex liner from DuraFlex or Olympia Chimney, sized to match your existing appliance output. OEM Famco liner is available for some older models, but in most cases a quality aftermarket liner outperforms it because current 316L alloys hold up better against acidic condensate than the original materials did. We’ll show you the spec sheet either way.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or metallic dust collecting on the fireplace floor or around the furnace base. This is liner material breaking down, not just surface rust on the damper. When the inner wall of a liner starts shedding, exhaust is already seeping through pinholes.
• A sour, acrid smell near the chimney even when the appliance hasn’t run for days. Condensate from flue gases soaks into the liner wall and masonry, and that smell doesn’t air out on its own. It gets worse in humid Hempstead summers, because the masonry holds moisture longer.
• Visible cracking, bulging, or separation at the liner seams. Famco liners were often joined with mechanical locks at the seam; when those fail, the liner sections pull apart. A flashlight and a mirror will show it if you know what you’re looking at.
• Your CO detector has gone off more than once, or the appliance flame burns yellow and lazy instead of blue. That’s not a liner diagnosis by itself, but combined with any of the above it means you stop using the appliance and call us at (516) 559-6922.
• Water staining on the ceiling near the chimney chase or on the wall behind the appliance. A compromised liner lets flue gas condense inside the chase, and that moisture migrates through drywall. By the time you see the stain, the liner has been leaking for a while.

Replacement Cost & What’s Included

In Hempstead, a single-appliance Famco liner replacement generally runs $1,800 to $2,800, and a two-appliance or taller chimney runs $2,500 to $3,400. What drives the range: liner diameter and length, whether we need to install a new cap or top plate, whether insulation wrap is required for safety code, and how much access we have from the roof. Every quote is a line-item written price you approve before we touch a tool, parts and labor separated, so there’s no mystery number at the end.

Every liner replacement we do carries our 365-Day Done Right Promise: a written guarantee valid for a full year from the service date. If a covered repair fails during that window, we return at no charge. That’s the Garrison Standard. No asterisk, no prorated fine print, no “we’ll get back to you.” If it’s not done right, we make it right.

DIY or Call Us?

You can check a few things safely from the ground: look for rust staining around the appliance connection, listen for a rattling sound inside the chimney on windy days, and check whether the liner cap is still seated on top of the flue tile. That’s inspection. The replacement itself is not a homeowner job. Removing a failed liner from a Hempstead chimney requires working from the roof, pulling a stainless tube through a tight flue, and making a sealed connection that won’t leak exhaust. If the connection isn’t right, you’ve traded a failed liner for a carbon monoxide risk behind a wall. That’s the cleanest way we can say it.

An honest conversation costs you nothing. Call us at (516) 559-6922, tell us what you think the liner is doing, and we’ll give you a straight answer about whether it’s worth a service visit or can wait until your next sweep. Hank Delano has spent the better part of two decades reading liner condition across Nassau County, including steady work in the Fulton neighborhood right here in Hempstead. The flue tells the truth. You just have to know how to read it.
