Famco Flue Liner Replacement in Los Angeles, CA

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

We stock and install Famco-compatible flue liner replacement in Los Angeles, with most jobs running $1,800-$3,400 installed depending on height, diameter, and whether the chase needs reworking. Same-day service is available when you call before noon, and we carry the common Famco diameters on every truck. Most Los Angeles homeowners discover the problem during a cold snap when smoke backs into the living room, or when a Level-2 inspection turns up spalling, gaps, or corrosion they never saw coming.

Which Famco Models This Applies To

Famco flue liners fall into several product lines, and matching the right replacement means reading the collar stamp or the data plate on the chase cover before we order anything. The stainless-steel Famco Wind Directional Cap series typically mates to 6-inch, 7-inch, or 8-inch round liners, while older galvanized chase covers from the 1980s and 1990s often conceal an oval or rectangular flue that needs custom transition work. We see this mismatch constantly in original-build homes from Sherman Oaks to Highland Park, where a standard round liner gets forced into an oval chase and fails at the joint within three seasons.

OEM Famco liner sections are still manufactured, but we also source quality aftermarket equivalents from Olympia Chimney and Copperfield when the original spec is discontinued or when the homeowner wants a heavier-gauge upgrade. The decision hinges on wall thickness: OEM Famco runs .005-inch to .007-inch in most residential lines, while we typically spec .010-inch or .012-inch 316Ti stainless for Los Angeles installations where salt air and thermal cycling from frequent small fires chew through thinner metal. If your chase cover still has a readable model number (usually stamped on the skirt or inside the collar), photograph it before you call. That one picture saves us a trip to confirm fitment.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke seepage into rooms or attic spaces. A compromised Famco liner loses its airtight seal at the joints or develops pinholes from condensation corrosion. In Los Angeles, where many homeowners burn only on December nights, that acidic moisture sits in the flue for weeks and eats stainless from the inside out.
• White or orange staining on exterior masonry. This is efflorescence and rust, respectively, and it means exhaust gases are escaping through gaps in the liner and condensing in the chimney structure. We see this pattern often in mid-century homes around the Foothills where clay tile was never lined at all and a later Famco retrofit is now deteriorating.
• Strong odor even when the fireplace is cold. A intact liner draws properly and contains combustion byproducts. When the Famco liner separates from the collar or cracks at a joint, those byproducts leak into the home’s air pressure envelope, and you smell them on warm afternoons when the stack effect reverses.
• Visible gaps or flaking metal when viewed from the top. If you can safely look down the flue with a flashlight, you may see the telltale curling or “alligator skin” of overheated stainless, or a gap where two liner sections no longer overlap correctly. Do not attempt to probe this; a damaged liner can have sharp edges and unstable sections.
• Deterioration accelerating after Santa Ana wind events. The sudden pressure changes and dry heat of a Santa Ana cycle stress expansion joints in metal liners. We have documented cases in Pasadena and Altadena where a Famco liner that passed inspection in March showed new separation lines by November after a particularly harsh wind season.

Replacement Cost & What’s Included

What drives the range: height of the chase (two-story homes in Los Feliz or Silver Lake run longer material), diameter and wall thickness selected, and whether the existing top plate or termination collar can be reused. Every estimate we provide is itemized before work begins. The number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers the installation in writing, no arguing, and the liner itself carries the manufacturer’s warranty against defects.

DIY or Call Us?

There is a short list of things a careful homeowner can check without risk: confirming the model number on the chase cover, photographing any visible rust or staining from ground level with a zoom lens, and noting whether the problem correlates with wind direction or specific weather. What you should not do is climb the roof, enter the attic to inspect the flue from below, or attempt to extract a damaged liner section yourself. Metal flue liners under tension can release suddenly, and the edges of failed stainless are razor-sharp. More critically, an improper liner installation creates carbon monoxide pathways that do not announce themselves until they cause harm.
