Olympia Chimney Flue Liner Replacement: The Hempstead Owner’s Guide

Olympia Chimney flue liner replacement in Hempstead typically runs $1,950 to $3,400 installed, depending on the liner height, diameter, and whether the old liner comes out clean or fights on the way out. We stock Olympia Chimney-compatible stainless liners on the truck for the most common sizes, so most Hempstead jobs get done in one visit. You usually find out the liner has failed during a Level 2 inspection, or when a sweep pulls out a section of liner that looks like burnt lasagna and shows it to you in the driveway.

Here’s the reality: Olympia Chimney builds solid appliance connectors and liners, but time, creosote acid, and Long Island’s freeze-thaw cycle eat at any liner eventually. Hempstead winters push moisture into masonry, spring leaks into the flue, and that mix accelerates corrosion on the inner wall. We replace the liner, not the whole chimney, in most cases.

Which Olympia Chimney Models This Applies To

This page covers replacement liners compatible with Olympia Chimney’s standard round stainless relining systems, including the Olympia 6-inch and 5.5-inch flex liners used in masonry chimneys serving oil burners, gas furnaces, and wood stoves. Olympia positions most of its liner products for relining existing masonry flues rather than new construction, so the replacement conversation usually starts with measuring the old liner’s diameter and the flue’s total run from appliance collar to chimney crown.

The compatibility gotcha: Olympia liners run slightly thinner wall than some trade equivalents, which means the original install often includes a specific top plate and rain cap sized to the liner’s exact OD. When owners swap in a different brand, they sometimes discover the old top plate no longer seats correctly. We spec the Olympia-compatible liner and matching components together so the top end seals like it should. If your liner’s label is gone or crumbled, we measure the flue with a camera and confirm diameter before quoting anything. OEM Olympia liners and quality aftermarket stainless equivalents are both options we carry; the difference comes down to your chimney’s specific dimensions and what Olympia part number, if any, is still legible on the collar.

Worth naming plainly: Flint Chimney Co Hempstead is an independent chimney service company. We are not affiliated with Olympia Chimney as a manufacturer. We buy, stock, and install their products because they hold up when installed correctly.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Rust stains or flaking metal on the smoke shelf or in the cleanout. Stainless liners do not rust gently. When you see reddish scale or metal flakes in the cleanout, the liner wall has started to lose its integrity, usually from acidic condensation on the flue gas side.
• A dry, hard creosote glaze that scrapes off in black sheets. This means the liner is not carrying heat the way it should. A failing liner with pinholes or separation lets flue gas cool too fast, which turns creosote from sooty powder into a hard, glassy deposit that is harder to remove and burns hotter if it catches.
• You smell soot or oil exhaust indoors, especially on windy days. A breach or disconnected seam in the liner lets flue gas press into the masonry cavity and leak through mortar joints into finished rooms. This is not a nuisance smell. It is a carbon monoxide pathway.
• White or gray staining on the chimney exterior brick near the top. That is moisture wicking out of the flue through the masonry. It means the liner is no longer containing the flue gas and condensation is migrating through the chimney walls, which also accelerates brick spalling in Hempstead’s freeze cycles.
• The water heater or furnace flue feels warm when it should be cool to the touch. A double-wall connector that runs hotter than normal on its exterior often means flue gas is backing up or the liner no longer drafts cleanly. It is a sign to stop running the appliance and get a camera in there.

Replacement Cost & What’s Included

For Hempstead homes, an Olympia Chimney-compatible flue liner replacement installed typically runs:

• Single-story reline, 15 to 20 feet: $1,950 to $2,600
• Two-story reline, 25 to 35 feet: $2,400 to $3,100
• Two-story reline plus top plate, rain cap, and connector: $2,900 to $3,400

What moves the number: liner height, whether the chimney crown needs a new top plate poured or patched, and what we find on the camera before the old liner comes out. If a section of the old liner is collapsed or fused to the flue wall, removal takes longer. We give you a written price before the job starts, and that price includes the liner, the labor to pull the old one, the new top plate, the rain cap, the connector at the appliance, and the full-year repair guarantee in writing. The number on the invoice is the number you approved. Not a dollar more.

DIY or Call Us?

You can do the diagnosis part without leaving the ground. Check the cleanout for metal flakes, look for rust trails on the exterior brick, and pay attention to indoor smells when the furnace kicks on. That tells you something is wrong, not what or where.

Replacing a flue liner is not a homeowner job. It involves lifting a section of flexible stainless up to the crown, dropping it down a masonry flue with bends, securing it at the top plate, and connecting it at the appliance collar with the right fittings. If a liner is dropped, kinked, or misaligned, it can block draft and push flue gas into the house. Carbon monoxide does not care how handy you are. And as Hank Delano puts it, The flue tells the truth. You just have to know how to read it. That reading happens with a camera, on a roof, with the right ladder and harness. If you are in Hempstead and suspect the liner is done, call (516) 559-6922 and we’ll put a camera in the flue before anything else happens. If the liner can wait, we’ll tell you that in plain English.
