Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Los Angeles Owner’s Guide

We stock and install Famco-compatible stainless steel flue liner replacements throughout Los Angeles, with most jobs running between $2,400 and $4,800 installed depending on liner length and roof access. We carry common Famco sizes on the truck, so a single-story home in the Valley can often be done same-day. Most owners discover they need this part after a chimney inspection flags cracks or separation, or after water starts streaking down the firebox after a good rain.

Famco makes a solid liner. But like any stainless component exposed to Los Angeles combustion byproducts and coastal air, it eventually corrodes at the seams or separates at a joint. When that happens, the fix is almost always replacement, not patching. Here’s what you need to know before you spend a dime.

Key Takeaways

• Famco flue liner replacement in Los Angeles typically costs $2,400 to $4,800 installed.
• We stock common Famco diameters (6″, 7″, 8″) on the truck, so most single-story jobs are a one-visit fix.
• Famco liners generally last 12 to 18 years in LA; coastal homes trend toward the lower end from salt air.
• You cannot safely patch a separated stainless liner; it must be replaced. We’ll explain why below.
• Every job gets a written price before work starts and a written guarantee when it’s done.

Which Famco Models This Applies To

This page covers Famco’s stainless steel chimney liner systems, including their 6-inch through 8-inch diameter flexible and rigid sections common in Los Angeles gas furnace and water heater venting applications. If you’re not sure what you have, look for a small metal tag on the liner cap at the top of the chimney, or check the inspection report from your last sweep. The tag will show the diameter and often the series number.

The compatibility gotcha with Famco specifically is the connector style. Famco liners use a crimped-end connection system, meaning the male end of one section slides into the female end of the next. If you buy a generic liner from a big-box store, the crimp depth is often shallower than Famco’s, which creates a loose joint that can separate under thermal expansion, which is exactly what a fireplace or furnace in Los Angeles does every winter morning when the heat kicks on. So we match crimp depth to the existing Famco sections, and if the original liner is too far gone to match, we replace the entire run so every joint is from the same system.

For most Los Angeles single-family homes, we recommend replacing with genuine Famco when the remaining liner sections are still sound and you’re only patching a failed segment. But if corrosion is widespread, we’ll quote a full replacement with either Famco or an equivalent from DuraFlex, which we also stock. The honest truth: for full replacements, DuraFlex and Famco are both quality 316L stainless systems, and we’ll give you pricing for both before you decide.

One more spec worth knowing: Famco liners are rated for continuous flue gas temperatures up to 570°F on the flexible models. That matters because some Los Angeles homes built in the 1960s and 70s have oversized furnaces that run hotter than modern units. If your home has an original furnace from that era, we’ll flag the temperature concern during inspection before recommending a liner swap.

Signs Your Famco Flue Liner Replacement Is Failing

• Water streaks or rust stains in the firebox after rain: This is the most common Los Angeles-specific failure, especially in hillside neighborhoods like Mount Washington and Silver Lake where chimneys take direct wind-driven rain. The stainless has corroded through or a joint has opened, allowing water down the flue. The liner needs replacement before the moisture rots the surrounding masonry.
• Flakes of metal or debris in the cleanout: When stainless liner sections start to break down, you’ll find small metallic flakes or thin rust-colored slivers in the cleanout at the base of the chimney. That’s delamination, and it means the liner wall is failing from the inside out.
• A sulfur or exhaust smell in the house when the furnace fires: This indicates flue gases are escaping at a failed joint and finding their way into the living space. This is a carbon monoxide risk, not just a nuisance. If you smell this, stop using the appliance and call us.
• Soot around the draft hood or burner area: When a liner separates, draft weakens, and the appliance can’t pull combustion gases up the flue efficiently. The result is soot backing up around the draft hood, the water heater, or the furnace connections.
• A chimney inspection report noting Stage 2 or Stage 3 cracking on an original clay liner that was sleeved with a Famco liner: When the original clay crack widens, the Famco liner can shift at its joints. We see this regularly in Brentwood and Westwood where older homes were built with clay tile that’s now spalling from decades of thermal cycling.

Replacement Cost & What’s Included

In Los Angeles, expect to pay between $2,400 and $4,800 for a Famco flue liner replacement, including the liner sections, connectors, top plate, cap, and installation labor. The spread is driven by roof pitch and chimney height: a single-story ranch in the San Fernando Valley with easy roof access runs the lower end; a two-story Spanish Revival in Los Feliz with a steep tile roof runs the higher end.

If it’s a partial replacement where we’re matching to existing sound Famco sections, the price drops accordingly, usually $900 to $1,600 depending on how many sections need to come out. We’ll write the price before we order or cut anything, and the number on your invoice will match the quote, no exceptions.

Every liner replacement includes a full camera inspection before and after, so you see exactly what came out and what went in. You get the written Kingswell Guarantee covering the repair for 365 days; if the liner fails in that window, we return and fix it at no charge under our 365-Day Done Right Promise.

DIY or Call Us?

You can safely do the diagnostic work yourself with a flashlight: look up the firebox for rust streaks, check the cleanout for metal flakes, and note any exhaust smell when the furnace cycles. Those observations help us quote accurately over the phone.

The replacement itself is not a DIY job. Cutting and crimping stainless liner sections on a Los Angeles roof, often a steep one, while pulling the old liner through the flue requires two people, proper roof anchoring, and a gas furnace that’s been correctly shut down and restarted. We’ve seen DIY liner installs where the sections separated at the joints within a year because the crimps weren’t seated, which is precisely the original problem. Call (213) 652-7061; we’ll look at your texted photos or do an on-site inspection and give you a written price before any work happens.
