Gelco Flue Liner Replacement: The Henderson Owner’s Guide
A Gelco flue liner replacement in Henderson typically runs between $1,850 and $3,400 installed, depending on liner diameter, length, and whether the old liner fights us on the way out. We stock Gelco-compatible stainless steel liners on the truck for common sizes, so most swaps happen in a single visit. The way Henderson owners usually discover a failed Gelco liner is not dramatic: a home inspection flags it, or they see fine sandy flakes collecting at the base of the firebox, or the fireplace starts drafting oddly in October when the desert nights finally turn cool enough for that first fire.

What matters most is this: a Gelco liner that has separated, corroded, or cracked is the only thing standing between combustion gases and the framing around your chimney chase. We’re going to walk you through what that means, what it costs, and what actually needs to happen so you can make a call without pressure.
Key Takeaways:
- Installed Gelco flue liner replacement in Henderson runs $1,850 to $3,400 for most single-story homes.
- We carry common Gelco-compatible liner diameters (5.5″, 6″, and 8″) on the truck for same-visit replacement.
- The 365-Day Done Right Promise covers the liner work. If it is not right, we make it right.
- We are an independent service provider, not affiliated with Gelco, and we install genuine Gelco parts or quality equivalents matched to your existing setup.
Which Gelco Models This Applies To
Gelco’s residential liner line runs through a few families: the standard Gelco stainless steel flex liners sized to the flue’s interior diameter, the Gelco Pro series with a heavier wall, and the insulated variants used inside exterior chases and manufactured fireplace flues. The single most common fitment mistake we correct on Henderson rooftops is a liner matched to the appliance’s listed flue collar size rather than the actual interior flue diameter the liner must pass through. A fireplace insert rated for a 6″ flue collar often sits inside a masonary or prefab flue that will only accept a 5.5″ liner once you account for corrugation and the bends in the smoke shelf. In Green Valley and Anthem homes with taller two-story chases, we measure the full liner run before quoting, because the add-on footage and the extra clamps at the top plate change the job.
OEM versus aftermarket for Gelco specific: Gelco’s own liners are well-built and we install them when the application calls for a direct match. But for many Henderson homes, a quality 316Ti alloy aftermarket liner of the same diameter and wall thickness performs identically and is often easier to source in the lengths desert two-story chases require. We will show you the tag on the liner we propose, explain the alloy grade, and note whether your existing Gelco liner was the insulated or the plain version. That detail matters in Henderson because uninsulated liners inside exterior chases lose heat fast, which increases creosote deposition in a way Nevada’s dry air already encourages. The desert’s low humidity sounds like a friend to steel, but the truth is Henderson winters swing thirty degrees between afternoon and midnight, and repeated thermal cycling is exactly what fatigues the corrugations on a flex liner faster than steady cold would.
Styles & brands we work with





Signs Your Gelco Flue Liner Replacement Is Failing
- Fine gray flakes or metallic dust in the firebox. Gelco liners delaminate at the inner wall before they visibly split. The flakes are the first warning; by the time you see them, the inner wall has started letting combustion moisture sit against the outer wall.
- Smoke roll-out when the fireplace is cold-starting. A liner with even a small crack changes the pressure balance of the flue. On chilly Henderson mornings, the cold air is heavier, and a compromised liner cannot keep draft consistent.
- A smell you cannot place when the fireplace has been off for days. That is often creosote or soot that settled into a liner seam and is being re-warmed by the afternoon sun against the chase. The smell drifts back into the living room when the damper is open.
- Brittle or pitted sections visible from the top with a flashlight. Henderson’s sun loads bake the exposed top section differently than the middle run. We frequently see Gelco liners that are entirely sound except for the top eighteen inches where UV has punished the protective coating.
- Your sweep report from a previous company noted “staging” or “early corrosion.” If that language appears on an old inspection, ask us to camera the liner before the next burn season. The desert’s dry air does not stop corrosion; it just slows it enough that people forget about it until the flakes show up.

AfterReplacement Cost & What’s Included
The installed price for a Gelco flue liner replacement in Henderson real terms: $1,850 to $3,400 for most single-family homes, and $2,900 to $4,800 when the chase is unusually tall, the liner is insulated, or the top plate and rain cap both need replacement at the same visit. The parts themselves, genuine Gelco or an equivalent 316Ti liner, account for roughly 40% of the quote. The rest is labor: rooftop access, pulling the old liner, prep, the drop, securing the top plate, and sealing everything at the appliance outlet. You will receive a written price before any work starts. That is not an add-on or a verbal ballpark; it is the number we charge, and it does not change after we start pulling liner. The labor and the liner are both covered under our 365-Day Done Right Promise, so if anything in that install is not right, we make it right within a year of the job.

DIY or Call Us?
What you can safely do is look: shine a flashlight up from the firebox and look for flaking, obvious separation, or shiny-edged cracks. You can also check the rooftop cap is still attached and not missing screws. What we strongly advise against is pulling the liner yourself. This is not a spring under tension like a garage door, but it is work on a roof with a thirty-to-forty-pound stainless steel snake involved. Getting a liner off a two-story Henderson chase without the right pulleys, gloves, and a second person on the ground is how people end up in the ER or with a liner in a neighbor’s pool. We carry the common diameter liners on the truck, so the swap is quick. Danny Cortes and the crew drop shoe covers at the door, lay drop cloths in front of the fireplace, and take a photo of the clean-up before we leave. If you are not sure whether the liner is actually gone, call us at (775) 485-5516 for a camera inspection instead of guessing; a camera look costs a lot less than a liner you did not need.
FAQs
In Henderson’s dry climate, a stainless steel Gelco liner will typically last 15 to 25 years, though we have seen top sections fail in under ten when exposed to heavy direct sun and chimney cap leaks that spray rain onto the hot metal. The liners that fail soonest are almost always uninsulated, improperly sized, or installed without a proper top seal. Nevada’s thermal swings shorten the metal’s fatigue life quietly, and by the time it is visible from the ground, the inner wall is already gone.
Small pinhole leaks near the top can sometimes be addressed by resealing the top plate and patching with a 316Ti band clamp, but any separation along the liner length means replacement. Patching a flex liner in the middle does not hold because the corrugated metal keeps working back and forth through every heat cycle. We will always tell you if the liner can safely wait, and we will show you camera footage either way.
Most Gelco flue liner replacements in Henderson take between two and four hours from rooftop setup to final vacuum. That includes pulling the old liner, dropping the new one, securing the top plate, sealing at the appliance outlet, and doing a draft check before we pack up. The camera inspection and photo report are part of the job, not an extra line item.
We stock Gelco-compatible liners and components on the truck in the diameters we see most often in Henderson: 5.5″, 6″, and 8″ flex liners, top plates, and rain caps. If we do need to special-order a specific Gelco part or an uncommon size, we tell you before the visit, and the written price stays fixed once we agree on the liner. We also carry DuraFlex and HeatShield products for applications where an insulation wrap or a specific alloy makes more sense.
If your Gelco liner is flaking, drafting with a mind of its own, or just reaching the end of its desert life, call us at (775) 485-5516 for a free estimate. We will camera the flue, show you exactly what is there, and give you a written price before any work begins. Know what’s in your flue before you light the first fire of the season.
