Most Cambridge homeowners discover their Famco liner has failed during a routine sweep or when they notice drafting problems the first cold week of October. The liner has been deteriorating for years, but the symptoms only become unmistakable when the heating season demands full performance. We’ve replaced Famco liners in homes from Harvard Square to East Cambridge, and the pattern is consistent: the liner does not fail dramatically, it fails gradually, and that gradual failure costs more in fuel and risk than an honest replacement.

Which Famco Models This Applies To

Famco manufactures several liner series, and matching the right replacement requires reading the collar label or measuring the existing run. The two most common in Cambridge are the Famco FAS series (flexible aluminum, typically 5- to 8-inch diameter) and the FSS stainless series (flexible 316Ti or 304, 5- to 10-inch). The FAS aluminum line was popular in 1980s and 1990s installations and has a realistic service life of 15 to 20 years in New England’s freeze-thaw cycle. We see these failing now in the triple-deckers and converted Victorians around Inman Square and Porter Square.

To identify your model, check the top termination collar for a stamped code, or measure the liner diameter with a tape measure across the inner wall. Do not measure the outer mesh. The FSS stainless series will have a .006-inch or .005-inch wall thickness marking. If your existing liner is FAS aluminum and shows any corrosion, we recommend upgrading to FSS stainless or an equivalent professional-grade stainless from our stocked DuraFlex or Olympia Chimney inventory. We are an independent service provider, not affiliated with Famco, and we source both OEM Famco replacements and certified-compatible alternatives based on what your chimney actually needs.

Signs Your Famco Flue Liner Replacement Is Failing

• Draft reversal or smoke spillage into the room. A compromised Famco liner loses its smooth interior surface, and creosote buildup or corrosion creates turbulence that prevents proper updraft. In Cambridge’s tight, older homes, this is often the first symptom a homeowner notices, especially on windy days when the house is under negative pressure.
• Visible rust flakes or aluminum oxide debris in the firebox. If you sweep out granular material that looks like dark sand or metallic flakes, your Famco aluminum liner is oxidizing from the inside. This material is corrosive and indicates the liner wall is thinning.
• Hot exterior masonry or discolored surrounding brick. The liner’s job is to contain heat and corrosive gases. When it fails, heat transfers to the chimney structure itself. We’ve found this in Cambridge’s 1890s brick stacks where the liner was original to a 1980s insert installation.
• Water staining on the ceiling near the chimney breast. A separated or perforated Famco liner allows combustion moisture to condense in the flue and leak through mortar joints. This is often misdiagnosed as a roof leak.
• Carbon monoxide detector alerts during appliance operation. This is the most serious sign. A breached liner can allow CO to escape into wall cavities or living spaces. If your detector alarms and your Famco liner is over 15 years old, stop using the appliance and call us.

Replacement Cost & What’s Included

Total installed cost in Cambridge typically falls between $1,800 and $3,400. The range depends on chimney height (a three-story Brattle Street run costs more than a single-flue ranch in North Cambridge), diameter, and whether we find deteriorated mortar joints that need tuckpointing before the new liner drops. We provide no-hassle upfront pricing before any work begins. The number on the estimate is the number on the invoice. Every Famco liner replacement is covered by our 90-Day Done Right Promise in writing, no arguing.

DIY or Call Us?

There is one thing a Cambridge homeowner can safely check: the termination collar at the chimney top for visible corrosion or separation. Use binoculars from the ground. Do not climb the roof.

Everything else requires a professional. Dropping a flexible liner through a chimney without damaging the new material or the masonry takes experience and the right pull rope setup. More critically, a liner that is not properly sized to the appliance, not connected with the correct adapter, or not terminated with proper clearance to combustibles creates a fire hazard and can void your homeowner’s insurance. The stainless steel itself is unforgiving; kink it during installation and you’ve compromised the wall. We complete most Famco liner replacements in a single visit because we bring the inventory, the camera, and the pull equipment on every truck. If it needs doing, we will tell you. If it does not, we will tell you that too.
