Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Houston Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Houston, with most installs running $1,800 to $3,400 depending on liner diameter, length, and whether the existing masonry needs prep work before the new liner goes in. Most Houston homeowners discover the problem during a Level 2 inspection after a chimney sweep, or when they notice flaking metal, rust stains, or a draft that suddenly got worse. The Famco liner is the inner pipe inside your chimney that channels smoke and gases safely out of the house, and when it fails, the fix is a replacement, not a patch. We carry Famco-spec liners on our trucks alongside DuraFlex, HeatShield, and Gelco equivalents, so most jobs are measured, quoted, and completed in one visit. Give us a call at (325) 750-6259 with your chimney’s measurements and we’ll tell you straight what a Famco flue liner replacement will cost in your part of Houston.

Which Famco Models This Applies To

Famco makes flue liners across several diameter ranges, and the compatibility question that trips up most Houston homeowners is this: the liner size is determined by the appliance it serves, not by the chimney’s outer dimensions. A furnace liner is typically 4 to 6 inches in diameter, a water heater liner runs 3 to 5 inches, and a fireplace or wood stove liner can run 6 to 12 inches. If you’re replacing a Famco liner, the old liner will have a stamped data plate or etched markings near the top or bottom connection point that give the diameter, material gauge, and sometimes the series code. The critical compatibility gotcha we see constantly in Houston’s older homes: Famco liners installed before 2010 were often 316L stainless steel, which is fine for gas, but if you’re switching from gas to a wood-burning insert, you need 316Ti or a heavier-gauge liner rated for solid-fuel temperatures. We’re an independent service provider, not affiliated with Famco, so our recommendation always comes down to what your appliance actually requires, not what’s easiest to source. For most gas appliance replacements, a Famco-compatible aftermarket liner from DuraFlex or Gelco performs identically and meets the same UL 1777 standard at a lower price point. For solid fuel, we spec the heavier material regardless of brand.

Signs Your Famco Flue Liner Replacement Is Failing

• Flaking metal or rust-colored debris at the base of the chimney. When a liner’s inner wall corrodes through, small pieces of oxidized metal drop down into the cleanout or firebox. Houston’s humidity accelerates this, especially in unlined exterior chimneys where condensation sits on the liner surface overnight.
• Visible staining on exterior brick or drywall near the chimney chase. A failing liner lets moisture and combustion byproducts seep through the masonry. In Houston’s climate, this often shows up as a dark, damp-looking patch that doesn’t dry out even in summer.
• A draft that’s weaker than it used to be. As a liner warps, cracks, or pulls away at the seams, the chimney can’t maintain the negative pressure it needs to pull smoke up and out. You might notice the fireplace is harder to light or smoke wafts into the room on windy days.
• A sulfur or gas smell near the fireplace or utility closet. If the liner is compromised, vent gases from a furnace or water heater can backdraft into the living space. This is a carbon monoxide risk and should be checked immediately by a professional.
• You can see gaps, holes, or separated seams with a flashlight. Shine a light up from the cleanout or down from the top and look for any light showing through where it shouldn’t. If you can see it with a flashlight, the liner is done.

If you’re seeing any of these in your Houston home, call us at (325) 750-6259. We’ll do a Level 2 inspection with a camera so you can see exactly what’s happening inside the flue before anyone quotes a dollar.

Replacement Cost & What’s Included

Installed Famco flue liner replacement in Houston typically runs $1,800 to $3,400. The range breaks down like this: a 4-inch by 25-foot gas furnace liner with installation usually lands around $1,800 to $2,200, while a 6-inch by 35-foot wood-burning fireplace liner can push $2,800 to $3,400 because the material is heavier and the install takes longer. What drives the spread in Houston specifically is chimney height (two-story homes in Meyerland and Bellaire need more liner footage than a single-story ranch in Spring Branch), access (roof pitch and whether we need a lift or can work safely from the roof), and whether the existing clay tile flue needs to be broken out to make room for the new liner. Every quote from Flint Chimney Co Houston includes the liner material, the top plate, the rain cap, the connection to the appliance, and the labor to pull the old liner and install the new one. You get a written price before any work starts, and the repair carries our 365-Day Done Right Promise: if a covered repair fails within one full year, we return at no charge. No deduction, no argument.

DIY or Call Us?

There are two things you can safely check yourself. First, look at the cleanout door at the base of the chimney and see if there’s rust debris or flaking metal sitting in there. Second, shine a flashlight up the flue from inside the firebox or from the top if you can get on the roof safely and see if you can spot gaps or holes. That’s where DIY ends. Replacing a flue liner means working on a roof, often with a rope and harness, while manhandling a stainless steel liner that can weigh 80 to 120 pounds. The liner gets pulled through the chimney from the top, which means someone is on the roof and someone is at the appliance connection point, and the whole job has to be coordinated so the liner doesn’t kink or tear on the way down. If it kinks, the liner is scrap. If you’re on a steep Houston roof in August heat and lose your footing, the cost of the liner is the least of your problems. This is a job for a trained crew with the right equipment. We’ve been doing this work in Houston for over a decade, and I’ve sketched more liner diagrams on a notepad for homeowners in Montrose than I can count. Tell me what you’re seeing, I’ll tell you what it costs to fix it. Call (325) 750-6259 and we’ll get you on the schedule.
