Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Olympia Chimney Flue Liner Replacement: The Greenwich Owner’s Guide
An Olympia Chimney flue liner replacement in Greenwich typically runs $2,400 to $4,800 installed, depending on liner diameter, flue height, and whether we’re pulling the old liner in one piece or breaking it out in sections. We stock Olympia-compatible stainless liners in 4″, 5″, 5.5″, 6″, 7″, and 8″ diameters on our trucks and can usually complete the swap same-day once we’ve confirmed measurements. Most Greenwich homeowners discover the liner has failed during a routine sweep when the camera shows a split seam, rust-through, or glazed creosote that won’t come off. The liner is the part that contains heat and combustion gases inside the flue, and when it goes, it goes quietly until someone looks.

Which Olympia Chimney Models This Applies To
Olympia Chimney built liners and venting components for a wide range of residential fireplaces, furnaces, boilers, and water heaters, sold through supply houses across the Northeast. The liner itself is matched by inside diameter and flue height, not by the fireplace’s model badge. Look at the metal tag on the appliance or the collar where the liner connects, and you’ll usually find a diameter stamped or printed. We measure the flue ourselves during the Level 2 camera inspection because the old liner’s ID is often distorted from years of heat cycling.
OEM Olympia Chimney liners are still available in some sizes, but much of what we install now is a quality aftermarket equivalent, a 316L or 316Ti stainless liner that meets the same UL 1777 listing and the same diameter spec. The fit matters more than the badge. That said, Olympia Chimney’s older 5.5″ liners can be an oddball. If the flue is straight and the height is typical for a Greenwich colonial, a 5.5″ liner will usually match cleanly to a 6″ appliance collar with a proper adapter. We stock that adapter on the truck because it catches people out. Level Two Chimney Co. is an independent service provider, not affiliated with Olympia Chimney.
Signs Your Olympia Chimney Flue Liner Is Failing

- Flaking rust or metallic debris at the cleanout door. Stainless liners don’t rust through quickly, but older Olympia Chimney aluminum liners do. Aluminum was common in the 1990s for gas appliances, and it does not hold up to years of acidic condensate. If you see silvery flakes, the liner is shedding material and needs replacement.
- Visible soot staining or moisture on walls adjacent to the chimney. Combustion gases are finding a path through a gap in the liner and condensing inside the masonry. This usually points to a cracked seam or a failed joint, not a cleaning issue.
- A sharp, acrid smell indoors when the fireplace or furnace runs. Exhaust is leaking into the chase or wall cavity. The liner’s job is to carry that gas out, and if you smell it, the liner has already lost containment.
- White powdery deposits on the liner surface during inspection. That’s creosote that has glazed and chemically attacked the metal. On stainless this often appears as pitting under the deposit; on aluminum it can corrode straight through.
- Water in the firebox after rain. Rain comes down the flue when the liner and cap connection has failed. Older Olympia Chimney liners without a properly sealed top plate let water run between the liner and the masonry, which accelerates rust from the outside in.

AfterReplacement Cost & What’s Included
A full Olympia Chimney-compatible flue liner replacement in Greenwich starts around $2,400 for a single-story straight run with easy roof access. Most jobs land between $3,000 and $4,100. The range is driven by three things: flue height, liner diameter, and how much of the old liner has to be cut out. If the old liner is seized in place with glazed creosote or rust-welded at the joints, we’re cutting it out in sections, which adds labor. If the crown needs rebuilding at the same time, that’s additional, and we’ll quote it separately in writing.
Our written price includes the liner, top plate, connector, mortar lock at the crown, the old liner removal, and the full camera-scan before and after. You get a written scope, a written warranty, and the photo record, all before work starts. That’s Haven Standard Clause 1 and Clause 4. Materials are sourced from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield through our buying network to keep pricing honest. Call (516) 399-5497 and we’ll measure the flue and hand you a written number, no obligation.
DIY or Call Us?

What you can safely check yourself: flaking debris at the cleanout, visible water staining around the chimney chase, and whether the cap is still attached. That’s evidence gathering, not repair. What you shouldn’t do is pull a liner yourself. A flue liner carries hot exhaust and creosote, and a liner job done wrong doesn’t just leak smoke, it can create a chimney fire or carbon monoxide hazard. This is not a parts-swap project. The old liner has to be extracted without damaging the flue tiles behind it, the new liner measured and cut to the exact height, and the top plate sealed so water stays out.
We’ve had Greenwich homeowners bring us photos of DIY liner kits that didn’t seat, gaps around the collar, and stainless liners kinked from being forced around an offset. A kinked liner is a contained fire starter. If you want the measurements, we’ll tell you the diameter and height, in writing. If you want it done, call (516) 399-5497 and we’ll quote it before touching a tool.
FAQs
A stainless 316L liner installed in a Greenwich home typically lasts 20 to 30 years, while older aluminum liners often fail in 10 to 15 because of acidic condensate from gas appliances and coastal humidity. The camera scan shows exactly where your liner falls on that range.
Small pinholes and minor seam separations can sometimes be addressed with a liner patch or a resurfacing product, but if the liner is rusted through in multiple spots or the seams have opened along a length of the flue, replacement is the only repair that holds. We’ll show you the camera images and you’ll see why.
Most Olympia Chimney-compatible liner replacements in Greenwich take 4 to 6 hours on site, including old liner removal, new liner installation, crown sealing, and the post-install camera scan. Same-day completion is typical unless the crown also needs repair.
We stock stainless liners in 4″, 5″, 5.5″, 6″, 7″, and 8″ diameters on our trucks, along with Olympia Chimney-compatible adapters and top plates, so we can usually measure and replace the same day. Call (516) 399-5497 and we’ll confirm the size over the phone before we arrive.
Bring us any written estimate and we’ll second-opinion it for free. We’re the chimney company that put the camera record on paper in 2009, and we haven’t changed the standard since. The camera doesn’t guess. Neither do we.
