Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Chesterbrook Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Chesterbrook, typically running $1,800-$3,400 installed depending on liner diameter and flue height. Most Famco jobs we book are completed in a single day once the scope is confirmed. Chesterbrook homeowners usually discover the issue during a routine sweep when our camera finds spalling tile, gaps at the mortar joints, or corrosion pinholes in a stainless Famco liner that has aged past its service window.

Which Famco Models This Applies To

Famco manufactured several liner series over the years, and the replacement strategy depends on which system is in your flue. The Famco 316Ti flexible stainless liners, common in Chesterbrook homes built between 1985 and 2005, carry a part number stamped on the top collar or termination cap. The Famco rigid 304 stainless systems, more often found in commercial or multi-flue setups near the Chesterbrook Corporate Center, use a different coupling method and require matching rigid sections rather than flexible pulls.

To identify yours: look for a metal tag at the top of the liner with a series prefix (FL-316, FL-304, or RL-rigid). If the tag is missing, we measure the inner diameter with a flue gauge and check the wall thickness with a caliper. A 316Ti flexible liner measures 0.006 to 0.010 inch wall thickness; rigid 304 runs 0.018 to 0.024 inch. Getting this wrong means ordering a liner that either will not fit the existing tee and termination or will sag in a tall flue.

We source replacement Famco-compatible liners through Haven’s buying network, which also stocks DuraFlex, HeatShield, and Gelco equivalents. In most Chesterbrook residential jobs, a quality aftermarket 316Ti liner from our network matches or exceeds the original Famco spec at a lower procurement cost. We pass that difference through and show you both options in writing before work starts.

Signs Your Famco Flue Liner Replacement Is Failing

• White or orange staining on the exterior masonry. This is efflorescence or rust bleed, and it means exhaust gases are migrating through gaps in the liner and condensing in the brick. In Chesterbrook’s freeze-thaw climate, that moisture expands every winter and accelerates spalling.
• Flakes of clay tile in the firebox or cleanout. If your original system had a clay liner that was sleeved with a Famco stainless insert, the clay is now deteriorating underneath. The Famco liner may still look intact from below while the clay collapses around it, constricting the flue.
• Smoke rollout when opening the firebox door. This points to a liner that has separated at a joint, creating a reverse-flow path. The draft pulls room air down the gap instead of exhausting up the flue.
• A sulfur or rotten-egg smell near the hearth. Corrosion pinholes in a 304 stainless liner, especially in homes that burn softwood or have run unseasoned cordwood, let combustion byproducts leak into the living space. Carbon monoxide risk is real here.
• The camera shows a “shiner” - light visible through the liner wall. This is the definitive finding. Any pinhole or crack that passes light fails the NFPA 211 Level 2 standard and requires replacement before the next burning season.

Replacement Cost & What’s Included

What drives the range: liner diameter (5.5-inch vs. 6-inch vs. 8-inch), flue height, whether we need to remove a damaged existing liner first, and if the smoke chamber or firebox needs parging before the new liner seats properly. Every quote in Chesterbrook is delivered in writing before work starts, with the scope, materials list, and warranty spelled out. That is Haven Standard Clause 1. The 365-Day Done Right Promise applies to every liner installation.

Your documented photo record, captured during the pre-work camera scan and post-install verification, is archived under Haven Standard Clause 4. You get a copy; we keep the master. This has been our practice since 2009.

DIY or Call Us?

There is exactly one safe check a homeowner can make: shine a flashlight up the flue from the firebox and look for obvious gaps, tile debris, or daylight where the damper frame should seal. Do not attempt to disassemble a Famco termination cap or pull a liner yourself. The top of a Chesterbrook colonial or center-hall is 25 to 35 feet up, often with a steep-pitch roof and no safe anchor point. Liner replacement requires proper fall protection, combustion-clearance knowledge, and a post-install pressure test or camera verification that the system is gas-tight.
