Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Bellevue Owner’s Guide

Famco flue liner replacement in Bellevue typically runs $1,800-$3,400 installed, depending on diameter, height, and whether the existing liner pulls clean or needs cutting out. We stock Famco-compatible stainless steel liners and connectors for same-day installation on most Bellevue homes with standard 6″ or 8″ systems. The camera doesn’t guess. Neither do I.

Most Bellevue owners discover the problem during a routine sweep or after a chimney fire scare. You smell smoke in the upstairs bedroom, or the sweep’s camera shows gaps between liner sections, or the metal itself has corroded through where condensation pools. In Bellevue’s wet climate, that last one is more common than people expect. We see it regularly in Lakemont and Somerset homes where the fireplace gets heavy winter use and the liner was original equipment from the 1980s or 90s.

Which Famco Models This Applies To

Famco manufactured several liner series over the decades, and the replacement approach differs by what you actually have in the flue. The most common in Bellevue are the Famco smooth-wall stainless series (typically 304 or 316 grade, marked on the collar) and the earlier corrugated flex lines that Famco sourced before bringing production in-house. The smooth-wall units carry a part number stamped on the top collar; if that collar has corroded off, we measure inner diameter and wall thickness with a caliper to match.

Here’s the compatibility gotcha: Famco’s 6″ smooth-wall will mate with some Olympia Chimney and Gelco adapters, but the collar depth and crimp direction vary by production year. A 2008 Famco collar is deeper than the 2015 revision, which means an aftermarket adapter can seat poorly and leak combustion gases. We carry both OEM Famco connectors and matched aftermarket equivalents from our Haven buying network, and we test-fit before the truck leaves the warehouse.

If your original liner is corrugated flex, we almost always recommend upgrading to smooth-wall 316 stainless. The corrugated profile traps acidic condensation in Bellevue’s marine climate, accelerating failure. We’ve documented this pattern across dozens of Bellevue inspections since 2009.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke odor in upstairs rooms or attic space. This means combustion gases are escaping through a gap or hole in the liner, often where two sections meet or where the liner passes the smoke chamber. In Bellevue’s tight, energy-efficient homes, negative pressure pulls that leakage into living space instead of up the flue.
• White or orange powder on the liner surface (camera view). That’s chloride corrosion from moist, acidic flue gases eating the metal. Once you see pitting, the wall thickness is compromised. We’ve measured Famco 304 liners in Bellevue homes at 40% of original thickness after 15 years of wet-season burning.
• Flaking or tile pieces in the fireplace. If your chimney was originally clay tile and a Famco liner was retrofitted, falling debris means the liner has shifted or collapsed, exposing the old tile. The liner is no longer protecting the masonry from heat and acid.
• Damp or stained chimney breast inside the house. Condensation leaking through liner defects soaks the surrounding brick. In Bellevue’s rainy season, this can look like a roof leak. The camera tells the difference in about 30 seconds.
• Difficulty starting or maintaining a fire despite dry wood. A compromised liner alters draft dynamics. If the liner has partially collapsed or separated, you’re fighting against restricted airflow and possible downdraft from the pressure imbalance.

Replacement Cost & What’s Included

What drives the range: height of the flue, diameter, condition of the existing liner, and whether the chimney has offsets that require sectional rather than continuous liner. Every quote is written before work starts, with the scope, the price, and the warranty on one page. Clause 1 of the Haven Standard. The 365-Day Done Right Promise applies to every installation.

What’s included: NFPA 211 Level 2 camera inspection before and after, the liner and all connectors pulled from our Famco-compatible inventory, proper insulation wrap where required by code, new top plate and cap, and a documented photo record uploaded to your file. Materials come through our Haven buying network from Famco, DuraFlex, HeatShield, Gelco, Olympia Chimney, and Copperfield. We don’t markup mystery parts.

DIY or Call Us?

There’s a safe middle ground here. You can check the collar marking with a flashlight and mirror, measure your flue’s inner diameter with a tape, and confirm whether your fireplace is factory-built or masonry. That information saves us time on the phone.

What you should not do: climb the roof to drop a liner, work inside the flue without proper respiratory protection, or attempt to cut out a stuck liner with power tools. The old liner can be under tension, sharp as a razor where it tore, and surrounded by fragile terra cotta that collapses without warning. Carbon monoxide doesn’t announce itself. We’ve been called to finish jobs where the homeowner got the old liner halfway out and realized the new one wouldn’t navigate the offset.

Corrine Halstead and our crew handle the full replacement with documented procedures, background-checked technicians, and license numbers on every page. Call (425) 696-0387 for a written estimate. Estimates are free. Second opinions on any competitor’s written quote are free too.
