Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Lawrence Owner’s Guide

Famco flue liner replacement in Lawrence typically runs $1,850 to $3,400 installed, depending on liner diameter, length, and whether your existing Famco liner sections can be reused at the joints. We stock Famco-compatible liner sections on the truck and can usually complete the swap in a single visit. Most Lawrence homeowners discover they need a liner replacement during an annual inspection, when our camera shows a crack, separation at a seam, or liner sections that have begun to flake into the flue. If you have a Famco liner that is failing, the fix is usually straightforward, but the decision about which sections to replace matters more than most people expect.

Which Famco Models This Applies To

Famco makes rigid stainless steel flue liner sections sold in standard diameters, most commonly 5.5″, 6″, 7″, and 8″, along with matching connectors, caps, and rain collars. The brand is common in older Lawrence homes, particularly in the Five Towns neighborhoods where oil-fired furnaces and older masonry fireplaces were retrofitted with steel liners years ago. The compatibility gotcha with Famco is this: their liner sections use a male-to-female slip joint, so if your liner was installed with the joints oriented the wrong way, condensation runs into the seam instead of past it. We have corrected that orientation on more Lawrence chimneys than we can count, and it is a common cause of early liner failure along the South Shore.

When we arrive, we check the etched label on the existing liner or measure the inside diameter with a caliper if the label is burned off. We treat Famco as an OEM-first job, but we also stock quality aftermarket equivalents from DuraFlex and Gelco for cases where a Famco-specific section is no longer made or would take too long to source. Top Hat Chimney is an independent service provider, and we are not affiliated with Famco. We match the metal grade and wall thickness, not just the diameter.

Signs Your Famco Flue Liner Replacement Is Failing

• Flaking metal or rust-colored dust at the cleanout door. This means the liner’s inner wall is shedding and the flue gas is no longer fully contained. On Famco liners, this often starts at a seam before spreading.
• A sulfur or oil-exhaust smell in the basement when the furnace runs. A cracked liner lets combustion gases seep into the house instead of venting up and out. This is the point where you stop using the appliance and call us.
• Water streaks or staining on the chimney exterior after rain. Condensation inside a failing liner can migrate through masonry. In Lawrence, salt air from the South Shore accelerates this, especially on older brick chimneys that were never sealed.
• Visible separation at a liner joint during an inspection. Famco sections can work apart over years of heating and cooling cycles. A separated joint is a draft killer and a carbon monoxide path.
• The liner has more than two patch repairs already. A patched Famco liner can limp along for a while, but after multiple patches the metal is telling you something. Full section replacement is usually cheaper than a third patch.

Replacement Cost & What’s Included

For Lawrence, expect the installed price for a Famco-compatible liner replacement to land between $1,850 and $3,400. The spread comes down to four things: the liner diameter, the length of the run from appliance to cap, whether any Masonry work around the crown or flue tile is needed, and how hard the access is on your roof. We give the price before any tool comes off the truck, and that number is what appears on your invoice. Here is a straight breakdown:

• Liner sections (Famco OEM or DuraFlex/Gelco equivalent): $28 to $45 per foot, depending on diameter and metal grade
• Labor for removal and installation: $650 to $1,100, including roof work and cleanup
• Connectors, cap, and rain collar: $120 to $260
• Camera inspection included: no charge, before and after

Every replacement carries the 90-Day Done Right Promise in writing. If something is not right, one call brings Wendell and his crew back. No argument, no second invoice. Seniors and veterans always get 10% off, and any repair over $200 takes $40 off right now.

DIY or Call Us?

Here is the honest split. You can safely do this yourself: look at the cleanout door and check for rust dust, note any smell when the furnace first kicks on, and take a photo of the liner label if you can reach it without getting on the roof. What you should not do: get on a Lawrence roof in January with a patch kit and a hope. Liner replacement means working at height on a pitch that is often icy near the coast, pulling sections out of a flue that may be hot or brittle, and sealing joints so condensation never finds a seam. A bad drop down the chimney or a liner section that slips and cracks the flue tile makes the job twice as expensive. This one is not a DIY job, and we would rather say it straight than patch up a Saturday-afternoon attempt later. Call (516) 604-2573 and we will inspect it and give you a real number.
