Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Southampton Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Southampton, with most jobs completed in a single visit and upfront pricing agreed before we start. Installed cost typically runs $1,800 to $3,400 depending on liner diameter, flue height, and whether the existing liner pulls clean or has to be cut out. Homeowners usually discover the problem mid-season, when a smoky fireplace, water in the firebox, or a failed Level-2 inspection reveals cracks, gaps, or corrosion they couldn’t see from below.

Which Famco Models This Applies To

Famco built several liner series over the years, and the replacement part you need depends on which one is in your chimney now. The Famco 316Ti stainless flexible liner, common in installations from the 1990s through the early 2010s, carries a part number stamped on the top collar or termination cap. If that label has weathered off, we measure inner diameter to the sixteenth and check wall thickness with a caliper at the cleanout. Famco also produced a 304-grade economy line with thinner walls, usually 0.005″ to 0.010″ lighter than the 316Ti, and those fail faster in Southampton’s salt-air environment.

We carry both OEM Famco replacement sections and compatible aftermarket from Olympia Chimney and DuraFlex in 5.5″, 6″, 7″, and 8″ diameters. The aftermarket equivalents match Famco’s corrugation pitch and coupling geometry, so they sleeve together without adapters. One compatibility gotcha: early Famco rigid liners used a proprietary top plate bolt pattern that does not mate with current universal caps. We stock both patterns on the truck, but it is worth knowing before we climb. We are an independent service provider, not affiliated with Famco.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke backing up into the room. A liner with separated seams or corrosion holes loses draft capacity. The flue can no longer establish the negative pressure that pulls combustion gases upward, so smoke finds the path of least resistance, which is often your living room.
• Water staining or puddling in the firebox. Cracks in the liner let rainwater run down the flue wall instead of shedding to the crown. In Southampton, where nor’easters drive rain sideways, even a hairline gap at a joint will find water.
• White or green powder on the liner walls. That is chloride salt corrosion, accelerated by coastal air. The 304-grade Famco liners are especially prone to it after fifteen to twenty years near the salt marsh areas of Shinnecock and Tuckahoe.
• Spalling brick or deteriorated mortar in the firebox. When exhaust gases leak through liner gaps, they condense on cooler masonry below. The acid in that condensation eats mortar from the inside out, a problem we see often in the older colonials along Jobs Lane where original construction predates liner installation.
• Failed inspection with visible gaps on camera. Our Level-2 inspection sends a camera up the flue and documents what we find. If the liner has shifted, buckled, or developed holes, the photo report shows exactly where and how large.

Replacement Cost & What’s Included

What drives the range: flue height, accessibility of the chimney top, whether the existing liner is intact enough to pull out as one piece or must be sectioned and removed, and whether the chimney needs refractory repair before the new liner drops. Our estimate includes the liner, top plate or termination cap, bottom connector, insulation if code requires it, labor, and disposal. The number on the estimate is the number on the invoice. Every Famco flue liner replacement we install carries our 90-Day Done Right Promise in writing. If it is not right, we come back. No paperwork, no arguing.

DIY or Call Us?

There is honest work a homeowner can do and honest work that belongs to a trained sweep. You can check the cleanout door for debris, shine a flashlight up the flue to spot obvious gaps or daylight, and verify your damper opens fully. What you cannot safely do is climb the roof, work at height with a liner that wants to kink or drop, or properly seat a termination cap with the correct storm collar and seal. The liner is heavy, the flue is a blind conduit, and a misaligned installation creates the exact carbon monoxide and chimney fire risks you are trying to eliminate. We have pulled more than one homeowner’s partial installation to do it correctly. Call (516) 619-2915 and we will price it upfront, show up when we say, and get it done in one visit.
