Olympia Chimney Flue Liner Replacement Nationwide

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

We stock and install Olympia Chimney-compatible flue liner replacement in Towson, with most jobs running $2,800-$4,500 installed depending on height, diameter, and whether the chase needs reworking. Our trucks carry Olympia Chimney liner inventory in common Towson sizes, so we can often measure and begin work the same week you call. Most Towson homeowners discover the problem during a routine sweep, or when they notice a hot smell in the wall or water staining near the fireplace after one of our wet Maryland winters.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures stainless steel flexible liners in 316Ti and AL29-4C alloys, and the alloy grade matters for what you’re burning. The 316Ti handles dry wood and standard venting. The AL29-4C is what you need for oil or gas condensing appliances, and mixing these up is a compatibility gotcha we see in Towson’s older homes near Rodgers Forge, where a furnace was swapped to high-efficiency gas but the liner never got upgraded.

Check the collar tag on your existing liner, usually visible at the top of the flue or just inside the thimble. You’re looking for the diameter (typically 5″, 6″, or 8″ in this market), the alloy stamp, and whether it’s a smooth-wall or corrugated construction. Olympia Chimney’s smooth-wall series carries roughly 20% better draft efficiency, but it won’t compress into a chase designed for corrugated. We’ve measured enough Towson chimneys to know the difference before we unload the truck.

On OEM versus aftermarket: Olympia Chimney builds to UL 1777 and UL 263 standards, and we source direct or through authorized distribution. For some Towson jobs, a DuraFlex or Gelco equivalent meets the same spec at lower cost. We’ll show you both options and the test documentation, then you decide.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Hot or smoky odors when the fireplace or furnace runs. This usually means gaps or separations in the liner joints, letting combustion gases leak into the chimney cavity. In Towson’s humidity, those gases condense and the smell lingers even after the fire is out.
• Water stains on the ceiling near the chimney breast. A compromised liner allows acidic condensate to reach the masonry instead of venting properly. We’ve traced this pattern in ranch-style homes off Joppa Road where the liner had pinholed at the offset.
• Flaking rust or orange staining at the cleanout door. This signals the liner has corroded through, often where it sits in the lowest, coolest section. AL29-4C liners resist this; 316Ti liners in oil service do not, and Towson still has plenty of pre-conversion oil heat.
• Difficulty starting or maintaining a draft, especially on mild days. A liner that’s collapsed, settled, or lost its insulation can create cold spots that stall the flue. Olympia Chimney’s smooth-wall helps here, but only if the original installation allowed for proper support spacing.
• Your sweep found gaps or holes during camera inspection. The camera doesn’t lie. We document what we see, show you the footage, and mark the timestamp. If the liner’s failed at multiple points, patching is usually throwing good money after bad.

Replacement Cost & What’s Included

What drives the range: chimney height above the roofline, whether we need to rebuild the top of the chase to accommodate a new cap configuration, and if the existing liner is cemented in place from a previous installer. We price this upfront, in writing, before any work begins. The number on the estimate is the number on the invoice. Every liner replacement carries our 90-Day Done Right Promise, in writing, no arguing.

DIY or Call Us?

There’s a safe middle ground and a hard stop. You can verify your liner diameter with a tape measure at the thimble, check the collar tag for alloy type, and photograph any rust or staining for us to review before we arrive. What you should not do: climb the roof to drop a liner, work with the appliance connected, or attempt to break loose a liner that’s been cemented in. The weight of a 25-foot stainless liner is significant, and a dropped section damages the liner, the roof, or you. We’ve retrieved enough homeowner attempts to say plainly: this is a two-technician job with proper rigging. Call (443) 785-3816 and we’ll measure, spec, and install it correctly.
