Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Jamaica Owner’s Guide

If your Famco flue liner has cracked, corroded, or delaminated, the replacement itself typically costs between $45 and $140 for the liner section depending on diameter and alloy, with full installed replacement in Jamaica running $1,900 to $4,200 including the liner, insulation, and labor. We stock Famco-compatible liner sections on our trucks and can usually complete a swap in a single visit once we’ve confirmed the diameter and length on camera. Most homeowners discover the failure one of two ways: a sweep flags it during an annual cleaning, or they notice flaky metal debris collecting at the base of the chimney, which is the liner shedding from the inside out.

Either way, you’re in the right place. This page covers exactly what we’ve learned replacing Famco liners across Jamaica over the years, including the row houses near Jamaica Avenue where the original flue work rarely matches the seller’s disclosure.

Which Famco Models This Applies To

Famco makes two product lines that show up regularly in Jamaica homes: their stainless steel chimney liner kits and their standard flue pipe sections for gas and oil appliances. The liner kits come in diameters from 4″ to 8″ and are sold in pre-measured lengths, while the flue pipe is typically 24″ or 36″ per section. The part you need depends on what the camera showed us.

Here’s the compatibility gotcha most people miss: Famco liners are sized by nominal diameter, and the actual outside diameter runs about a quarter inch wider. If your existing liner measures 5.75″ across with a tape measure, that’s a 6″ nominal liner, and you’d order the 6″ replacement. Mixing nominal and actual measurements is the single most common ordering mistake we see. We verify this with a camera measurement during inspection, not a guess from the ground.

On the OEM versus aftermarket question: Famco’s own replacement sections are solid, mid-grade 316 stainless, and they’re what we use when the original liner is less than 15 years old and the rest of the system is intact. But if your liner is older, or if the camera shows pitting and thinning at the lower third where condensation pools, we’ll often recommend a heavier 316L alloy from our other stocked brands like DuraFlex or HeatShield. They cost about 15 to 20 percent more, but in a damp Queens flue, that extra chromium buys real time. We’re an independent service provider, not affiliated with Famco, so we’re free to tell you when a different brand is the better call.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust-colored flakes at the cleanout door or firebox floor. This is delamination, meaning the liner’s inner wall is shedding thin layers of corroded steel. Once it starts, the liner is finished, not fixable.
• A metallic rattle when wind gusts across the chimney cap. Loose liner sections can separate at the seams and vibrate against the masonry. It sounds like a loose gutter bracket, but it’s coming from inside the flue.
• Visible staining or efflorescence on the chimney exterior, especially after rain. When the liner fails, flue gases condense inside the brick and push moisture outward. You’ll see white chalky deposits or dark streaks on the face of the chimney.
• The smell of exhaust or sulfur in the room with the appliance, even with the damper closed. A compromised liner can let flue gases seep back into the house. This is the one symptom you should treat as urgent, not a project for next month.
• Your CO detector reading low-level spikes near the boiler or water heater flue. We’ve seen readings under 10 ppm that the homeowner ignored because they were intermittent. A failing liner is the most common culprit we trace it back to.

In Jamaica’s older housing stock, especially the 1920s and 30s rowhouses, we regularly find liners that were never properly sized for the appliance they serve. An oversized liner cools the flue gases too fast, which accelerates condensation, which rusts the liner from the inside. That’s a design problem, not a Famco defect, and it means the replacement has to be matched to the appliance, not just swapped one-for-one. Corrine Halstead has written up enough of these to know the pattern by heart.

Replacement Cost & What’s Included

Here’s what we quote in Jamaica, in writing, before any work starts:

• Famco-compatible liner section (4″-6″ diameter): $45-$95 per piece, depending on length and alloy
• Famco-compatible liner section (7″-8″ diameter): $85-$140 per piece
• Insulation wrap and mesh: $85-$160 per job
• Labor, standard single-story chimney access: $1,100-$1,700
• Labor, two-story or steep pitch roof in Jamaica: $1,400-$2,100
• Full installed replacement, typical range: $1,900-$4,200

The range comes down to three things: how tall the chimney is, whether the old liner comes out cleanly or fights us, and whether the crown needs any patching while we’re up there. Every quote includes the liner, insulation, removal of the old section, camera verification after install, and a photo record you keep. That’s Clause 4 of the Haven Standard, and it’s been standard on every job since 2009, not an add-on.

Warranty on the work runs through our 365-Day Done Right Promise. If it’s not right, we come back and make it right. The materials themselves carry their manufacturer’s warranty, and we register it for you.

DIY or Call Us?

We’ll be straight with you: this is not a DIY job. Removing and replacing a flue liner means working on a roof, handling a section of steel that can weigh 30 pounds or more, and sometimes using a winch to pull the old liner through a brick flue that hasn’t been touched since the house was built. One bad lift and you’re looking at a damaged crown, a torn liner, or a fall. We train for this and we still respect it every time.

What you can safely do: check the cleanout door for rust flakes, note any new staining on the chimney face, and write down the make and model of your boiler or furnace so we can verify the liner size when we’re there. That’s genuinely helpful, and it saves us a trip. But the swap itself belongs to someone with a roof harness and a winch, not a ladder from the garage.

If you’re in Jamaica and the liner’s failed, call us at (516) 240-9612. We’ll put a camera down the flue, show you what we see, and hand you a written price before anything gets ordered.
