Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Hoffman Estates Owner’s Guide

We stock and install Famco-compatible flue liner replacements in Hoffman Estates, typically ranging from $1,850 to $3,400 installed depending on liner diameter, flue height, and whether the existing liner is stainless or aluminum. Most Famco liner swaps we book in Hoffman Estates are completed in a single day, with the new liner sized from our on-truck inventory of 6″, 7″, and 8″ diameters. Homeowners usually discover the problem during a sweep when our camera shows cracked tiles, corroded aluminum, or a liner that’s pulled away from the top collar, leaving bare masonry exposed to flue gases.

Which Famco Models This Applies To

Famco manufactured two distinct liner product lines that remain in Hoffman Estates homes: the FL-Series flexible stainless liners (2005-2018) and the earlier AL-Series rigid aluminum systems (1998-2007). The FL-Series carries a part number stamped on the top termination collar, format FL-XX-YY where XX is diameter and YY is length in feet. The AL-Series used a riveted tag on the first section above the smoke chamber, now often corroded illegible after fifteen-plus winters of freeze-thaw cycling.

Here’s the compatibility gotcha we run into regularly in Hoffman Estates: Famco’s FL-Series used a proprietary 7.25″ outer diameter on its 6″ inner liner, slightly oversized compared to the 7″ OD standard that DuraFlex and Olympia Chimney adopted. Drop a standard 7″ OD replacement into a Famco FL-6-25 chase and you’ll have a half-inch gap that defeats the purpose. We carry both the true Famco-spec replacement and the HeatShield sleeve system that can adapt a standard liner to that chase without a full rebuild.

For the AL-Series, we do not recommend OEM-equivalent aluminum replacements. The material failed predictably in our climate, where temperature swings from -15°F to 105°F stress thin-wall aluminum at the joints. We upgrade these to 316Ti stainless, sourced through our Haven buying network, which carries a lifetime warranty against corrosion perforation.

Signs Your Famco Flue Liner Replacement Is Failing

• White or orange staining on exterior brick below the roofline. This is efflorescence and rust from condensing flue gases escaping through liner cracks. In Hoffman Estates, we see this most often on north-facing walls where the chimney stays cold and wet longer.
• Bits of clay tile in the firebox after burning. Famco systems installed over original clay liners sometimes concealed spalling tile underneath. The pieces fall when the stainless or aluminum liner shifts or corrodes through, no longer supporting the debris.
• Smoke smell in upstairs bedrooms when the fireplace is not in use. A separated top collar or split flexible liner allows reverse draft on cold days. Hoffman Estates’ flat terrain and tree-lined lots create negative pressure zones that pull air down the flue.
• Water in the cleanout or rusted damper. Famco’s AL-Series used a simple slip-fit top plate that loosened as aluminum expanded and contracted. Once the seal fails, every driving rain runs straight down the flue.
• Carbon monoxide detector alerts near the chimney breast. This is the one that gets our immediate attention. Any liner failure that allows exhaust into wall cavities or floor joist bays creates a genuine hazard, not a maintenance item.

Replacement Cost & What’s Included

What drives the range: liner diameter, total linear feet from appliance to termination, whether we need to remove a damaged existing liner or it has already collapsed, and access (steep roof pitch, enclosed chase that needs siding removed). Every quote we deliver in Hoffman Estates includes the liner material, new top plate and rain cap, bottom connector, insulation wrap where required by NFPA 211, and disposal of the old liner.

Before any work starts, you’ll receive a written price, written scope, and written warranty under Haven Standard Clause 1. The 365-Day Done Right Promise applies to every liner installation. We also provide a documented photo record per Clause 4, showing the full camera scan of the new liner in place, not just the before pictures.

DIY or Call Us?

There’s a safe middle ground and a hard stop. You can verify your Famco model from the collar stamp or tag, measure your flue length with a weight and string, and inspect the cleanout for debris or water. What you cannot safely do is remove a failed liner from a two-story flue, work on a steep roof to replace the top termination, or properly torque the bottom connector to a factory-built fireplace without risking a gap that leaks carbon monoxide into the wall.

We’ve retrieved more than one homeowner’s stuck DIY liner attempt from Hoffman Estates chimneys. The cost to extract and reinstall correctly usually exceeds our original installed quote. Camera first, price second, pen third - in that order every time. If you’re unsure whether your Famco liner is salvageable, call (331) 200-4445 and we’ll schedule a Level 2 inspection with no obligation.
