Gelco Flue Liner Replacement Nationwide

Gelco Flue Liner Replacement: The Henderson Owner’s Guide

Gelco flue liner replacement in Henderson typically runs $1,800 to $3,400 installed, depending on liner length, diameter, and what we find during the chimney camera inspection. We stock Gelco-compatible stainless steel liner sections on our trucks, so most replacements go in the same day we diagnose the failure. The way most Henderson homeowners discover the problem is through an annual sweep: the brush pulls back a chunk of rusted liner, or the camera shows a seam that has separated and is venting into the chimney chase instead of up and out.

If your Gelco liner has failed, the fix is not a patch job. A compromised liner is the single most important barrier between combustion gases and the framing of your house. We replace it with new rigid or flexible stainless sections sized to your exact flue dimensions, and every job carries our 365-Day Done Right Promise in writing before the first tool comes off the truck.

Which Gelco Models This Applies To

Gelco liners are specified by diameter and length, not by a particular fireplace brand. The two most common sizes we replace in Henderson are 5.5-inch and 6-inch round liners, usually in lengths between 15 and 35 feet. If you still have the original paperwork, the model number starts with the liner diameter; if not, we measure the existing flue opening during the inspection. That measurement, not the model number, is what determines the correct replacement.

One compatibility gotcha that catches Henderson homeowners off guard: Gelco liners installed before roughly 2010 were often single-wall stainless, while newer installs are typically double-wall or insulated. You cannot simply swap a single-wall section for whatever is on the shelf at a big-box store. The wall thickness, insulation wrap, and connector type all have to match the existing setup or you create a new failure point. We also carry DuraFlex and HeatShield liner components for homes where the Gelco system was paired with a different brand’s top plate or cap, since those connection points are where we see the most corrosion in Henderson’s dry, hot summers and occasional hard rain.

Flint Chimney Co Henderson is an independent service provider. We are not affiliated with Gelco, but we have installed and replaced enough of their liner systems across Henderson to know exactly which sections interchange and which do not.

Signs Your Gelco Flue Liner Replacement Is Failing

• Rust flakes in the firebox or on the smoke shelf. This is the most common first sign. The liner’s inner wall is oxidizing, which means the stainless has been exposed to sustained heat and moisture cycles. In Henderson, the swing between daytime heat and cold desert nights accelerates this corrosion on older single-wall liners.
• A persistent smell of smoke even when there is no fire. That odor means combustion residue is sitting somewhere it should not be. A failing Gelco liner seam allows creosote and soot to collect between the liner and the chimney structure, and that smell drifts back into the house.
• Visible gaps or separation at the liner seams. If you have access to the top of the chimney, you may see sections pulling apart. Do not attempt to climb onto a Henderson roof to check this yourself. We use a camera system that goes up from inside, so you stay on the ground.
• Water or dark staining on the ceiling near the chase. A liner failure plus a compromised chimney cap can let moisture into the chase, and that water shows up as staining on drywall long before you see any other symptom. This is one we see regularly in Green Valley Ranch homes from the late 1990s and early 2000s.
• Your last sweep report noted “liner deterioration” or “recommend liner replacement.” That is not a suggestion to think about next year. A liner that is shedding rust is past the point of cleaning and into replacement territory. We put that finding in writing with camera images so you can see exactly what we see.

Replacement Cost & What’s Included

A Glenco flue liner replacement in Henderson, done correctly, runs $1,800 to $3,400. The low end covers a straightforward 15-foot, 5.5-inch liner with a standard top plate and cap. The high end covers longer runs, 6-inch or larger diameters, insulated double-wall systems, or a chase that needs a repair before the new liner goes in. The single biggest cost driver is liner length, followed by whether the existing top plate and cap can be reused.

What that price includes: the liner sections, the connector hardware, the top plate, the cap if it needs replacing, the install labor, and a full camera inspection after the swap so you can see the finished job for yourself. We hand you a written price before any work starts, and that number is the number on the invoice. No add-ons at the door. The entire replacement carries our 365-Day Done Right Promise: if a covered repair fails within a year, we return and fix it at no charge.

DIY or Call Us?

You can do one thing safely: look inside the firebox with a flashlight from the floor. Rust flakes, visible seams separating, or a dark, crusty buildup are indicators that something is wrong. What you should not do is get on a Henderson roof with a ladder and attempt to remove or repair a flue liner. A liner runs the full height of the chimney, and pulling a section out without the right tools can drop debris into the firebox, damage the chase, or leave you on a roof with a section of sharp stainless in your hands and no way to secure it. The liner is also the only thing keeping exhaust gases inside the flue, so a half-finished DIY job is a carbon monoxide risk, not just a cosmetic one.

If you suspect the liner has failed, call (775) 375-4267. We will inspect it with a camera, show you the footage, and give you a written price for a replacement. Tell me what the flue looks like, and I’ll tell you what it costs, no guessing, no padding.
