Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The San Diego Owner’s Guide

A Famco flue liner replacement in San Diego typically runs between $1,800 and $3,400 installed, depending on the liner diameter, length of the run, and whether the existing liner needs to be extracted first. We stock Famco-compatible stainless steel liners on our trucks for most common sizes, so the swap is usually done in a single visit. Most homeowners discover the problem the same way: a Level 2 chimney inspection flags a crack, or they notice flaky rust-colored bits collecting at the base of the fireplace after a winter of steady use.

If you’re reading this, you probably already know the Famco liner in your chimney has seen better days. Maybe a technician told you it’s failing. Maybe you saw water in the firebox. Either way, we’ll walk through exactly what replacement looks like for a Famco product, what it should cost in San Diego, and how to know whether it truly needs to come out or can wait another season.

Which Famco Models This Applies To

Famco has been manufacturing venting and flue components for decades, and here’s the compatibility gotcha most people run into: Famco liners are sized by inner diameter, not outer, and their wall thicknesses run light compared to some aftermarket equivalents. If you’re replacing a Famco liner with a generic that measures the same on the outside, you might unknowingly choke your flue by a quarter inch. “That matters more than you’d think,” Nathan Corliss says. “A quarter inch of diameter loss changes your draft velocity, especially on shorter San Diego chimneys where we don’t get much vertical rise to work with.”

Common sizes we see on Famco installations across San Diego are 6″, 7″, and 8″ inner-diameter liners in 304 or 316 stainless. You can identify yours by looking at the stamped tag on the liner cap or the first section extending above the chimney crown. If the tag is corroded, a cross-liner measurement at the top gives us what we need. For most homeowners, an OEM Famco replacement in 316 stainless makes sense only if the chimney is within three miles of the coast – “the marine layer is merciless on 304,” Nathan notes. “Inland, 304 holds up fine and saves you real money.”

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or discoloration at the cleanout or firebox base. The liner’s interior is breaking down, usually from condensation carrying acidic combustion byproducts. On coastal San Diego homes, salt-laden moisture accelerates this. If the flakes are dark and oily, that’s creosote, not rust – a sweep may be all you need.
• Faint smoke smell in the house hours after a fire. Gaps in a failing liner let combustion gases seep into the chase or wall cavity instead of venting upward. The smell tends to come and go, which is exactly why it’s easy to dismiss. It shouldn’t be dismissed.
• Water in the firebox after rain. Cracked liner sections let water travel down the flue path instead of being carried out by the cap. “We see this a lot in Del Cerro and La Mesa homes from the 1980s,” Nathan says. “The original Famco liners were solid, but once one seam failure starts, they all follow.”
• Visible cracks or gaps during an inspection. We see this constantly during Level 2 inspections. Not every hairline crack means replacement, but the inspector’s camera report will show the difference. If you’ve been told there’s a crack and you haven’t seen the camera image, call us for a second look before committing.
• Pieces of liner material in the firebox or on the smoke shelf. This is late-stage failure. The liner has lost enough structural continuity that pieces are sloughing loose – “the chimney equivalent of a tire losing tread,” as Nathan puts it. Replacement is no longer optional at this point, because there’s a real possibility of flue gases entering the home.

Replacement Cost & What’s Included

For a straight replacement in San Diego with reasonable access, here’s what we quote:

• Standard 6″ Famco-compatible liner replacement, single-story, 15-25 ft run: $1,800 – $2,400 installed.
• 7″ or 8″ liner, longer run, or second-story roof access: $2,300 – $3,100 installed.
• Existing liner extraction that’s corroded in place: add $250 – $450 depending on obstructions and how much of the old liner comes out in one piece.

The price includes removal and disposal of the old liner, the new stainless liner cut and fitted to your exact run, a new top plate and rain cap, the locking clamp and connector, and a foam or refractory insulation pour if your clearance-to-combustibles requires it. You get the number in writing before we touch the chimney – we follow the Kingswell Way. Say the price first, explain the work, put the promise in writing. Every liner replacement carries our 365-Day Done Right Promise: if the repair fails within the guarantee period, we come back and correct it at no charge.

DIY or Call Us?

Replacing a flue liner isn’t a candle or a filter swap – it’s structural venting work, and it involves working off a roof, often near a live flue, and fitting stainless sections through masonry that may have shifted over the years. The liner itself is under no tension, but the stakes are high: a poorly seated liner joint can vent carbon monoxide back into the living space. This is a job for a trained chimney technician with the right tools, and honestly, the third or fourth homeowner who tries this themselves ends up calling us anyway, usually after a Sunday afternoon spent on the roof with a liner that’s now wedged halfway down a flue.

What you can safely do: visual inspection of the cap and top section from the ground, checking the cleanout for debris, and shutting down the fireplace until the liner is assessed. If you think your Famco liner might be failing, call (619) 693-1499 and we’ll schedule an inspection with camera footage you can see with your own eyes. A written price comes before any work, and the estimate costs you nothing.
