Olympia Chimney Flue Liner Replacement: The Yonkers Owner’s Guide
If your Olympia Chimney flue liner has failed, you’re looking at a replacement that typically runs $2,400 to $4,800 installed in Yonkers, depending on the liner diameter, length, and whether the old liner needs extraction before the new one goes in. We stock Olympia Chimney-compatible liner kits on the truck and can usually perform the full swap in a single day once we’ve confirmed your flue dimensions. Most Yonkers homeowners discover the liner has failed in one of two ways: either a chimney sweep finds cracking during an annual inspection, or they notice flue tile fragments collecting at the bottom of the firebox after a winter of heavy burning.
Which Olympia Chimney Models This Applies To
Olympia Chimney builds stainless steel chimney systems for both masonry and factory-built applications, and their liner replacement needs differ depending on which product line you’re working with. The most common Yonkers installs we see are the Olympia Ventis and Olympia Excel series, though we also service the slightly older Olympia Galaxy and Olympia Supreme lines. If you’re not sure which you have, look for the UL listing plate on the firebox face or inside the firebox door frame. That plate gives us the exact model number and lets us confirm whether we’re matching a standard 6-inch, 7-inch, or 8-inch stainless liner, or working with an ovalized or custom profile.
A note on OEM versus aftermarket parts, specifically for Olympia Chimney: Hadley Chimney Yonkers is an independent service provider, not affiliated with Olympia Chimney, and in our experience the best replacement liner for an Olympia system is not always an Olympia-branded liner. They make a good product, but the wall thickness and alloy grade matter more than the logo. A 316Ti stainless liner from any reputable manufacturer will outlast a standard 304 in a wood-burning application, because the titanium-stabilized alloy resists the chlorides created when creosote combusts. We carry DuraFlex and Gelco liners that meet or exceed Olympia’s specs, and we’ll show you the gauge and alloy on the invoice so you know exactly what you’re paying for.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- Flue tile fragments in the firebox. When a clay liner cracks, pieces fall down inside the chimney and land where you can see them. This is the one symptom that means stop burning immediately. The crack creates a direct path for heat and embers to reach combustible framing.
- White or gray staining on the exterior chimney brick, especially after rain. Condensation inside a failing liner pushes moisture through the masonry, and those mineral deposits are the tell. In Yonkers, with our freeze-thaw cycles, this moisture also accelerates brick spalling, so it compounds.
- Rust flakes or scaling on the interior liner walls visible during an inspection. If we can see the stainless liner is pitting or peeling, the metal has lost its protective chromium oxide layer and will continue thinning until it perforates.
- Smoke odors in rooms adjacent to the chimney, even when there is no active fire. A compromised liner lets gasses migrate into wall cavities instead of drafting up and out. This is also how carbon monoxide enters living space, so it is not a wait-and-see situation.
- Hard brown or black glazed creosote deposits that scrape off in shiny sheets. That is stage-three creosote, and it burns hot enough to crack clay liners. If you have this, the liner likely already has damage you cannot see without a camera.

AfterReplacement Cost & What’s Included
In Yonkers, a full Olympia Chimney flue liner replacement typically runs between $2,400 and $4,800 installed. The spread comes from three factors: the diameter and length of the liner run, whether we are relining a straight vertical flue or working around an offset or smoke shelf, and whether the existing liner needs to be broken out and extracted before the new one drops in. A straight 6-inch by 25-foot stainless liner install on a single-story Yonkers home with an accessible roofline will land near the bottom of that range. A two-story with an offset and a deteriorated clay liner that has to be removed first lands near the top.
Every quote from Hadley Chimney Yonkers includes the liner kit, the insulation wrap when the manufacturer specifies it, the cap, the appliance connector, and the labor to install and document the whole thing. We hand you a written price before any work starts, and that price is the price. If the liner fails within 365 days, our Done Right Promise means we come back and make it right, free. You will also get before-and-after photos from inside the flue so you can see the old liner out and the new liner seated, not just take our word for it.
DIY or Call Us?
Flue liner replacement on an Olympia Chimney system is not a reasonable DIY project, and we say that as a company that fully supports homeowners who want to understand and even handle smaller chimney maintenance themselves. The problem is the liner has to be sized to the appliance, sealed correctly at the top and bottom, and insulated where it passes through unconditioned attic space, and getting any of those three wrong creates a fire hazard or a draft problem you will not know about until you light a fire on a cold Yonkers night. This is not like swapping a rain cap.
What you can safely do is shine a flashlight up from the firebox to look for obvious flue tile damage, and check the cap for corrosion. If you see anything concerning, Cory Mitchell and the crew will take a camera the rest of the way up and show you exactly what we find. If I wouldn’t leave it on my own fireplace, I’m not leaving it on yours. Call (914) 233-3156 and we’ll get you scheduled.
FAQs
A properly installed 316Ti stainless liner in a wood-burning Yonkers chimney typically lasts 15 to 25 years, while a 304 stainless liner under the same use usually gives you 10 to 15. The killer here is burn frequency and creosote management. We see liners from the 1990s in Yonkers homes that are still intact, and we see 8-year-old liners that have perforated because the homeowner never swept and burned wet wood. Annual sweeps extend liner life more than any product choice you make.
In most cases, no. Small vertical cracks in a clay liner can sometimes be addressed with a HeatShield resurfacing treatment, and we do offer that service, but once a stainless liner has perforated or the clay tile has separated and shifted, the only correct fix is replacement. A patch over a perforated liner will fail within a season or two because the thermal cycling keeps working the damaged area. Call (914) 233-3156 and we will camera your flue so you can see exactly what is repairable and what is not.
Most Olympia Chimney flue liner replacements in Yonkers are done in one visit, typically 4 to 7 hours from setup to final photo documentation. If the old clay liner needs to be broken out and extracted, add a few hours. We will give you a written time estimate along with the written price before we start, and you’ll get live arrival tracking through The Relay Visibility Guarantee so you know when we’re pulling up, not just a vague window.
We do. We keep common 6-inch and 8-inch stainless liner kits, tees, caps, and connectors on the truck, along with DuraFlex, HeatShield, and Gelco components for Olympia Chimney applications. If your setup requires a nonstandard size, we order it and typically have it in hand within two to three business days. The call is free and so is the assessment: (914) 233-3156.
