Homeowners usually discover the problem during a Level-2 inspection, or when they notice pieces of crumbling liner in the firebox, water staining around the thimble, or a persistent smoky smell even when the fireplace isn’t running. In older homes near New City’s historic districts, we’ve found liners installed in the 1980s and 90s that have simply reached end of life, especially where acidic flue gases from oil conversions accelerated corrosion.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures several liner series, and the replacement protocol differs by what you have. The OL series (round flexible stainless, .006″ wall) and OLY series (heavy-duty .012″ wall for oil and wood) are the most common in Rockland County homes. The OLR rigid line appears less frequently but requires exact matching of section lengths, since rigid liners don’t compress or extend like flex.

To identify your liner, check the top plate or collar for an embossed Olympia part number, or measure the inner diameter at the thimble connection. Most New City installations are 6″ or 8″ round, though we’ve encountered 7″ and oval conversions in pre-1970s masonry. The label matters because Olympia’s collar spacing and top termination geometry are proprietary, and mixing brands at the connection points creates draft problems we see every season.

We install OEM Olympia liners where the full system is being replaced, but for partial failures we also source compatible aftermarket from DuraFlex and Gelco when the connection geometry permits. Russell Haines makes that call during the camera inspection, and we’ll show you exactly why on the screen before you decide.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Flakes or powder in the firebox. Stainless liners corrode from the inside out, often where flue gases condense in the cooler upper sections. What you’re seeing is the liner wall degrading, and once flaking starts, the remaining thickness deteriorates faster.
• Water stains on interior walls near the chimney chase. A breached liner allows exhaust gases to cool prematurely in the masonry cavity, causing condensation that migrates through brick. In New City’s freeze-thaw climate, this also accelerates exterior spalling.
• Smoky odors when the system isn’t running. This usually means the liner has separated at a joint or corroded through, allowing downdrafts to pull creosote odor into living spaces. It’s often mistaken for a damper problem until the camera goes up.
• Visible gaps or sagging at the thimble. Olympia flex liners can settle over decades if the top plate wasn’t properly tensioned during original install. A sagging low spot collects condensation and creosote, speeding corrosion.
• Your oil or gas technician red-tags the venting. This is the definitive sign. When a combustion appliance test shows spillage or inadequate draft, and the liner is original to a 1980s or 90s install, replacement is almost always the fix.

Replacement Cost & What’s Included

What drives the range: chimney height above roofline (two-story colonials in New City average 25-35 feet of liner), whether the existing liner can be extracted without dismantling the top course of brick, and whether the appliance connection needs reworking. We quote the full number before booking, and that’s the number on the invoice. Our 90-Day Done Right Promise covers the installation in writing, no arguing.

Every replacement includes a post-install camera inspection with photos you keep, and we register the warranty with Olympia Chimney on your behalf.

DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY ends.

What you can check: verify your model series from any remaining label, measure the flue diameter with a tape measure at the thimble, and look for obvious damage from the firebox side with a flashlight. Document what you find. That information saves us time and saves you money on the diagnostic.

What you should not attempt: pulling a failed liner, dropping a new one, or making the appliance connection. The old liner may be wedged with creosote buildup or corrosion-welded at joints. The new liner must be sized to the appliance’s BTU output and vented correctly, or you risk carbon monoxide spillage or a chimney fire. We’ve retrieved DIY attempts from chimneys in New City and Nanuet where the homeowner got the liner halfway down and realized the offset was wrong. If it’s not right, we don’t leave until it is, but we’d rather be the ones who do it right the first time.
