Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Arlington Heights Owner’s Guide

We stock and install Famco-compatible flue liner replacements for Arlington Heights homeowners, with typical installed pricing running $2,400-$4,800 depending on liner diameter, height, and whether the existing liner is fully extracted or collapsed in place. Most Famco stainless steel liner jobs in Arlington Heights are completed in a single day, and we carry common diameters from 5″ to 8″ on our trucks. You’ll usually discover the failure during a sweep when the camera shows gaps, corrosion scaling, or complete separation at the collar joint, or when you spot water staining on the firebox wall after a hard Arlington Heights rain.

Which Famco Models This Applies To

Famco manufactured several liner series over the years, and identifying the right replacement starts with what’s left of the label. The Famco FLS series, common in Arlington Heights homes built between 1985 and 2005, used 316Ti stainless steel with a distinct rolled collar at the top termination; the FLS-II upgraded to 304 alloy with a welded seam and slightly heavier gauge. Check the collar plate near the flue top, or what we can reach of it, for a stamped model prefix. If the label’s gone to corrosion, we measure inner diameter at three points and check wall thickness with a caliper, since Famco’s 6″ nominal often measures 5.875″ actual, a tolerance that matters when mating to a new appliance adapter.

We source replacement Famco-compatible liners through Haven’s buying network, same as our DuraFlex, HeatShield, and Gelco materials, which keeps customer prices honest. For most Arlington Heights installations, we use a 316Ti alloy equivalent that meets or exceeds the original Famco spec; OEM Famco stock is no longer manufactured, so “genuine” claims in this market are worth questioning. The compatibility gotcha we see most often: Famco’s FLS series used a proprietary top plate bolt pattern that doesn’t mate cleanly with standard DuraFlex or Olympia Chimney termination caps without a fabricated adapter. We build those adapters in-house rather than forcing a universal fit that gaps in winter.

Signs Your Famco Flue Liner Replacement Is Failing

• Water staining on the firebox ceiling or side walls. Famco liners in Arlington Heights fail at the collar joint first, where freeze-thaw cycling opens a gap that lets combustion gases condense and run back down the flue. The stain pattern is usually a broad, light brown fan shape, not a single drip point.
• Flaking metallic debris in the cleanout or hearth. This is 316Ti or 304 alloy shedding its oxide layer after the protective chromium surface has been compromised, typically by sustained moisture exposure from a missing or degraded chimney cap. The flakes are magnetic, thin as paper, and a sign the liner wall is thinning structurally.
• Smoke odor in upstairs rooms during shoulder season. A separated Famco liner leaks combustion gases into the chimney cavity, and those gases find paths through balloon framing common in Arlington Heights colonials and split-levels along Campbell Street and the neighborhoods near Recreation Park. The smell is sharp, acrid, and often worse on humid days.
• Visible gaps or daylight through the liner wall on camera inspection. Our Level 2 inspection puts a camera down the flue, and a failed Famco liner shows either circumferential cracking at joint sections or longitudinal splits where the alloy work-hardened around a tight bend. Either condition is a carbon monoxide pathway into the living space.
• Appliance performance drop after years of normal operation. If your furnace or water heater suddenly struggles to draft and the Famco liner is original to a 1990s installation, the liner may have collapsed internally, creating a partial blockage that chokes the flue without fully obstructing it. We’ve pulled collapsed Famco liners in Arlington Heights that reduced effective flue diameter by 40% before the homeowner noticed anything wrong.

Replacement Cost & What’s Included

What drives the range: liner diameter and length, whether we’re extracting a fully separated liner or cutting and collapsing a seized one, and whether the flue has offsets that require flexible liner rather than rigid. Every quote is delivered in writing before work starts, per Haven Standard Clause 1, with the written scope, written price, and written warranty on one page. The 365-Day Done Right Promise applies to every installation, and our photo record, Clause 4 of the Haven Standard, documents liner condition before and after. Materials are sourced through Haven’s buying network from Famco-compatible, DuraFlex, HeatShield, Gelco, Olympia Chimney, and Copperfield suppliers.

DIY or Call Us?

There’s exactly one thing an Arlington Heights homeowner can safely check without training: look up the flue from the firebox or cleanout with a flashlight for obvious gaps, heavy staining, or debris accumulation. Do not attempt to measure, extract, or replace a flue liner yourself. The risks are specific and serious. A failed Famco liner may be partially collapsed and under tension; pulling it without proper anchoring can release stored energy unpredictably. More critically, an improperly sized or sealed replacement creates a carbon monoxide pathway into occupied space, and the consequences don’t announce themselves until they’re severe. Arlington Heights requires a permit for liner replacement, and the village inspector will verify UL listing and proper termination height. We’re licensed for this work, we pull the permit as part of the job, and we coordinate the inspection. Call (331) 202-2419 when you’re ready for a written price.
