Famco Flue Liner Replacement Nationwide

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

We stock and install Famco-compatible flue liner replacement in Jersey City, with most jobs running $1,800-$3,400 installed depending on liner diameter, flue height, and whether the existing liner is stainless or terracotta. Our trucks carry the common Famco diameters - 6-inch, 7-inch, and 8-inch round in both rigid and flexible configurations - so we’re not waiting on a warehouse. Most Jersey City homeowners discover their Famco liner has failed during a Level-2 camera inspection, often after noticing draft problems, water stains near the hearth, or a persistent smoky smell that doesn’t clear even with the damper wide open.

Which Famco Models This Applies To

Famco built flue liners across several product lines over the decades, and the replacement part you need depends on when your system was installed and what fuel it serves. The Famco stainless flexible liners - common in Jersey City row houses from the 1980s and 1990s - typically carry a part number stamped on the top collar or a tag near the thimble. Rigid Famco liners, more often found in pre-war brownstones in Paulus Hook and the Heights, may have no visible marking at all; we identify these by measuring the inner diameter with a caliper and checking wall thickness at the cleanout door.

We match OEM Famco specs where they still exist, but we also install quality aftermarket equivalents from Olympia Chimney and DuraFlex that meet or exceed the original UL 1777 rating. The key compatibility gotcha in Jersey City: Famco liners installed before 1996 were often sized for coal-to-oil conversions, running slightly narrower than modern gas or pellet specs. A 6-inch Famco from that era may not handle the BTU load of a current high-efficiency furnace without drafting problems. We verify appliance output against liner capacity before we quote - no guesswork, no callbacks.

Signs Your Famco Flue Liner Replacement Is Failing

• Draft that reverses or stalls. A Famco liner with separated seams or corrosion pinholes loses the tight draw that pulls combustion gases upward. In Jersey City’s older housing stock, we see this most often where the liner passes through an uninsulated exterior chase - freeze-thaw cycles work the seams open over fifteen to twenty winters.
• White or orange staining on the chimney breast. These salts are creosote and moisture leaching through cracks in the liner wall. The stain means flue gases are reaching the masonry surrounding the flue, and that masonry is absorbing the moisture those gases carry.
• Bits of metal or tile in the cleanout. Flexible Famco liners shed flakes of stainless when the alloy fatigues; rigid terracotta liners chip when the house settles, which Jersey City’s fill-ground construction makes more likely than most owners realize.
• Carbon monoxide detectors triggering near the fireplace. This is not a nuisance alarm. A breached Famco liner can vent combustion gases into wall cavities or floor joist bays. We treat every CO call as urgent and inspect same-day when possible.
• Water in the firebox after rain, even with a cap in place. The liner’s job is to contain combustion gases, but a sound liner also sheds condensate downward to the cleanout. A failed liner lets water migrate through cracks into the firebox or smoke shelf.

Replacement Cost & What’s Included

What drives the range: flue height (a three-story Jersey City brownstone runs more material than a two-story detached), whether we can pull flexible liner or must build rigid sections joint-by-joint, and if the existing liner has collapsed and needs extraction before the new one goes in. We quote the full number before we start - no surprises on the bill. Every Famco liner replacement carries our 90-Day Done Right Promise in writing. If it’s not right, we come back until it is.

DIY or Call Us?

There’s a short list of things a Jersey City homeowner can safely check: verify the damper opens fully, confirm the cap isn’t clogged with debris, and look for obvious water entry from the exterior. Beyond that, flue liner work involves working at height on a roof that may be steep, handling sharp stainless edges, and - most critically - confirming that the replacement liner is sized correctly for the appliance it serves. An undersized liner creates creosote buildup and potential chimney fire conditions. An oversized liner cools flue gases too quickly, causing corrosive condensation that destroys the new liner within seasons.

We don’t recommend DIY liner replacement. The inspection that follows installation is as important as the installation itself, and that requires a camera and training to interpret what the image shows. Call (732) 507-9649 and we’ll walk through what you’re seeing, no charge for the conversation.
