Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Sherman Oaks Owner’s Guide

Famco flue liner replacement in Sherman Oaks typically runs $2,800-$4,200 installed, depending on diameter, height, and whether the chimney chase needs reframing. We stock Famco-compatible liners and connectors in our Haven warehouse, and most Sherman Oaks replacements are scheduled within 48 hours of inspection. Most homeowners discover the problem during a routine sweep or when they spot rust flakes in the firebox, water stains on the ceiling near the chimney breast, or a persistent smoky smell even with the damper open.

Which Famco Models This Applies To

Famco manufactured flue liners under several product lines, and the identifying marks matter. Look for a stamped metal tag near the top of the chimney chase or embossed lettering on the liner collar itself: series numbers typically read FL-6, FL-8, or FL-10 for residential wood-burning applications, with the number indicating nominal diameter in inches. The FL-6 and FL-8 lines were most common in Sherman Oaks homes built between 1965 and 1995, especially the split-levels and ranch-style houses south of Ventura Boulevard where Famco had strong distributor relationships with local masons.

Here’s the compatibility gotcha: Famco used a proprietary twist-lock collar on liners manufactured before 1992. Post-1992 units switched to a standard three-bolt flange. If your collar is seized or corroded, you can’t eyeball the difference from the firebox. We drop the camera first, document the collar type under Haven Standard Clause 4, and match the replacement to the existing anchor pattern so your chase cap seals properly. The OEM Famco liner is no longer in production, but we source equivalent 316Ti stainless through our Haven buying network, rated for the same 2,100°F peak and carrying the same 20-year thermal warranty. We also stock DuraFlex and Gelco equivalents when the chase geometry demands a more flexible pull.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or orange staining in the firebox. This means moisture is getting past the liner joints, usually at a failed seam or corroded collar. In Sherman Oaks, the morning marine layer accelerates this: condensation forms in the cool flue, sits in low spots, and eats the steel from the inside out.
• Smoke backing up into the room on startup. A liner with internal scaling or a detached section creates turbulence that prevents proper draft. The smoke should rise; when it doesn’t, the liner’s interior surface is no longer smooth enough to maintain laminar flow.
• Water stains on drywall or ceiling near the chimney. The liner’s job is to contain combustion gases and shed any infiltrating water back out the top. A cracked or separated liner lets water track down the chase, past the smoke shelf, and into your framing.
• Chunks of clay tile or liner material in the cleanout. If your original system had a clay liner with a Famco stainless insert, the clay is now spalling from freeze-thaw stress or age. Those chunks mean the structural liner is compromised, and the Famco insert is working alone.
• Acrid, persistent odor even when the fireplace is cold. Creosote has penetrated porous spots in the liner or accumulated behind a detached section. Class III creosote, the hardened, tar-like stuff, bonds to damaged steel and off-gasses even at room temperature.

Replacement Cost & What’s Included

What drives the range: diameter, total liner length from firebox to cap, roof pitch and access, and whether the existing chase cap can be reused. Every quote we write in Sherman Oaks includes the liner material, NFPA 211 Level 2 camera inspection before and after, a written scope with line-item pricing, and the 365-Day Done Right Promise stamped on the work order. No surprises. We don’t start until you have the price in writing, Haven Standard Clause 1.

DIY or Call Us?

There’s a safe middle ground, and then there’s the part that’ll cost you more to fix than the original job.

What you can check safely: verify the model stamp if it’s legible, measure the firebox opening and existing collar diameter with a tape measure, and photograph any rust or water stains for reference. That information speeds our quote and confirms we’re matching the right part.

What goes wrong with DIY liner replacement: the liner arrives coiled and spring-tensioned. Uncoiling it improperly kinks the stainless, and a kinked liner is scrap. The pull requires a rope, a weighted cone, and usually a second body on the roof to guide the liner down without snagging on framing or existing clay tile shards. Most importantly, the liner must be continuously supported and the top seal verified with a smoke test. A liner that settles or gaps at the collar leaks carbon monoxide into the chase cavity. In Sherman Oaks, we’ve been called to three homes in the past two years where a homeowner-installed liner separated at the collar within the first season. The camera doesn’t lie, and neither does the written quote. Call (424) 414-6048 and we’ll scope it, price it, and do it once.
