The damper is the metal plate that seals your flue when the fireplace is not in use and opens it when you burn. On Olympia Chimney systems, it sits at the top of the firebox throat, and after fifteen to twenty years of Long Island heat cycles and salt air exposure, the mechanism that should glide open starts to grind, stick, or seize entirely. We see this most often in the older colonials near Caleb Smith State Park Preserve, where the original Olympia Chimney dampers are simply reaching end of life.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactured several damper series over the years, and the part you need depends on the vintage of your system. The cast-iron throat dampers from the 1980s and 1990s carry a 13-inch by 13-inch or 16-inch by 16-inch plate size, while later stainless steel pivot dampers use a different frame geometry altogether. The model number is usually stamped on the damper frame itself, visible when the plate is fully open and you shine a light up the flue.

Here is the compatibility gotcha we run into regularly in Smithtown: some Olympia Chimney systems installed in the early 2000s used a proprietary pivot pin spacing that does not match generic aftermarket dampers. A standard 16-inch replacement will bolt in and look correct, but the pivot geometry is off by three-eighths of an inch, and the plate will not seat fully closed. We carry both OEM-spec Olympia Chimney dampers and precision-matched aftermarket equivalents from Gelco and Copperfield, and we measure the pin centers before ordering so you do not pay for a part that leaks smoke.

OEM versus aftermarket for Olympia Chimney is not a quality question so much as a fit question. The OEM casting is heavier and carries the original part number, but the Gelco and Copperfield equivalents we use meet the same ASTM standards and often ship faster. For most Smithtown homeowners, the aftermarket route saves forty to sixty dollars without sacrificing function, provided the measurements are right.

Signs Your Olympia Chimney Damper Repair Is Failing

• Cold air pours down the chimney even when the damper is closed. The plate has warped or the frame has corroded at the seal edge, leaving a gap that lets outside air straight into your living room. In Smithtown, this is most noticeable on the north-facing exposures off Jericho Turnpike, where winter wind finds every crack.
• The handle or chain moves, but the plate does not open or close fully. The pivot pin has sheared, or the linkage inside the throat has separated from corrosion. This is common on Olympia Chimney systems where the original steel linkage was never upgraded to stainless.
• You smell smoke in the room shortly after lighting a fire. The damper is stuck partially closed, restricting draft and forcing exhaust into the house. This is not a nuisance; it is a carbon monoxide risk, and the fire should be extinguished until the damper is repaired.
• The handle requires force or makes a grinding noise. Creosote has built up on the pivot points, or the frame has rusted enough that the plate binds in its track. Forcing it usually bends the plate and turns a repair into a full replacement.
• Water stains appear on the firebox walls below the damper. The plate is not seating flush, allowing rain and melting snow to leak past and pool in the firebox. In Smithtown’s freeze-thaw cycles, that water accelerates deterioration of the firebrick and smoke shelf.

Replacement Cost & What’s Included

For Smithtown homeowners, Olympia Chimney damper replacement breaks down as follows:

The range depends on three factors: whether we can reuse the existing frame or need to replace it, whether the smoke shelf below the damper has deteriorated and needs refractory patching, and whether the original linkage runs through the masonry side wall or is accessible from the firebox. We price the job before we start, and the number on the estimate is the number on the invoice. Every damper repair includes a Level-2 camera inspection of the flue above, photos you can see, and our 90-Day Done Right Promise in writing.

We are not affiliated with Olympia Chimney; we are an independent service provider that stocks their compatible parts because they are common in Suffolk County homes built from the 1970s through the early 2000s.

DIY or Call Us?

There is one safe check a homeowner can make: with the fireplace cold and no ash present, open the damper fully and shine a flashlight up the flue to see if the plate is intact and seated squarely in its frame. If you see a cracked plate, a missing chunk of cast iron, or daylight showing around the edges when it should be closed, the repair is beyond hand tools.

The danger is not the damper itself but what surrounds it. The plate sits at the top of a narrow throat, often above a smoke shelf that is not designed to bear weight. Reaching it requires working at height inside the firebox, and the pivot pins are under spring tension on some Olympia Chimney models. A slipped wrench can send a cast-iron plate down onto your face or hands, and the creosote dust you disturb is a respiratory hazard. We have the camera gear to inspect without dismantling, and the right wrenches to extract the old pivot pins without damaging the frame. For most Smithtown homeowners, the risk and the mess are not worth saving a service call.
