Olympia Chimney Flue Liner Replacement Nationwide

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

We stock and install Olympia Chimney-compatible flue liner replacement in Smithtown, with most jobs running between $2,800 and $5,200 installed depending on length, diameter, and whether the appliance is wood-burning or gas. Our crews carry Olympia Chimney stainless steel liners and connector components on the truck, and we can typically inspect, measure, and begin installation within a few days of your call. Most Smithtown homeowners discover their liner has failed during a routine sweep when our camera catches cracked tiles, gaps at the joints, or corrosion thinning the metal - sometimes after smelling smoke in an upstairs room or finding creosote leaking into the attic space.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures flexible stainless steel liners in 316Ti and AL29-4C alloys, with diameters from three to twelve inches and lengths up to thirty-five feet. The critical match is not just the brand name but the alloy grade paired to your fuel type: 316Ti for wood and standard oil, AL29-4C for high-efficiency gas and pellet appliances that produce condensing flue gases. We’ve replaced Olympia liners in Smithtown homes where the previous installer used 316Ti on a condensing furnace, and the metal rotted through in under eight years.

To identify your liner, check the top termination for an embossed alloy stamp, or have us drop a camera and read the collar tag. We also see homeowners confuse Olympia Chimney’s liner products with their venting accessories - the liner itself is the flexible tube running inside your masonry flue, not the cap or storm collar above. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney, though we source their products through authorized distribution and also stock DuraFlex, HeatShield, and Gelco equivalents when the application calls for them.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Smoke or odor seeping into living spaces. A breached liner allows combustion gases to escape through gaps in the masonry. In Smithtown’s older colonials near Caleb Smith State Park Preserve, we’ve found tile liners collapsed at the offset where the flue turns to miss a stairwell, sending smoke into bedroom walls.
• Visible creosote staining on exterior brick or in the attic. This means gases are cooling and condensing before reaching the top, usually because the liner is too large for the appliance or has separated at a joint. The stain is often the first thing a homeowner notices, and it means the liner has been leaking for some time.
• Chunks of clay tile in the cleanout or hearth. Original terra cotta liners spall and crack from thermal cycling, especially after chimney fires. If you’re sweeping out fragments, the structural liner is gone and combustion gases are contacting bare brick.
• Rust streaks from a stainless liner’s top collar. Even quality 316Ti will corrode if exposed to salt air or if condensate pools at a low spot. Smithtown’s proximity to the Sound accelerates this at coastal properties - we check for collar seal integrity every time.
• Your heating technician red-tags the appliance. A failed liner is a code violation under NFPA 211. The red tag means do not operate until repaired, and in our experience it’s non-negotiable with any reputable fuel company.

Replacement Cost & What’s Included

For a typical Smithtown single-flue chimney, Olympia Chimney liner replacement breaks down as follows:

What drives the range: flue length (a three-story colonial on Landing Avenue runs longer than a ranch near Route 25), diameter (a six-inch wood stove liner costs less than an eight-inch fireplace liner), and whether we need to remove a damaged existing liner first. We agree to a flat price before booking, and that number appears on the invoice. No surprises. The liner carries the manufacturer’s warranty, and our installation is covered by the 90-Day Done Right Promise - in writing, no arguing.

DIY or Call Us?

An owner can safely check three things: whether the cap is intact and screening is clear, whether the cleanout door at the base opens and closes, and whether there’s visible debris or staining in the firebox. Beyond that, flue liner work involves working at height on a pitched roof, handling sharp stainless edges, and properly sizing combustion air for the appliance - get any of it wrong and you’re looking at carbon monoxide intrusion or a chimney fire.

We’ve been called to Smithtown jobs where a homeowner installed a liner too short, leaving a gap at the thimble that dumped exhaust into the basement for two winters before detection. The savings evaporated fast. If your Olympia Chimney liner is showing any of the symptoms above, call us at (631) 814-2057. We’ll camera the flue, show you what we see, and give you a number you can compare.
