Most Pottstown homeowners realize their damper has failed when they feel a cold downdraft even with the fireplace “closed,” or when smoke backs into the room on the first fire of the season.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures throat dampers in several series, and the part you need depends on when your fireplace was built and the flue opening dimensions. The most common we see in Pottstown are the 24-inch, 30-inch, and 36-inch galvanized throat assemblies, plus the stainless retrofit dampers Olympia produces for pre-fab metal chimneys. Check the stamped model number on the damper frame itself - it’s usually visible from the firebox with a flashlight, often reading “OLY-” followed by a four-digit code. If the tag is rusted away, we measure the throat opening width, depth, and lintel height on-site.

We are an independent service provider - not affiliated with Olympia Chimney - so we source both OEM replacement dampers and quality aftermarket equivalents from Famco and Copperfield when the original part is back-ordered or discontinued. For most Pottstown homes built between 1985 and 2010 with masonry fireplaces, the aftermarket stainless pivot damper from Famco outlasts the original galvanized unit in our wet freeze-thaw winters. The exception: pre-fab chimney systems where the damper is integrated into the chimney cap assembly. Those require exact OEM matching or the draft dynamics go wrong.

Signs Your Olympia Chimney Damper Is Failing

• Cold air pours down the flue even when the damper is “closed.” The plate has warped or the seal gasket has degraded, leaving a gap that lets outside air bypass. In Pottstown’s older homes near Manatawny Street, we see this constantly after decades of heating-season expansion and summer humidity contraction.
• You smell damp fireplace odor in summer. A damper that won’t seal tight allows humid air to settle in the firebox and breed musty smells. The gasket material Olympia used in the 1990s hardens to plastic after fifteen to twenty Pennsylvania winters.
• The handle is stuck, wobbles, or has fallen off entirely. The pivot pin corrodes or the linkage cable frays. Once the handle mechanism fails, the damper plate often hangs crooked and never seats properly again.
• Smoke spills into the room when you light a fire. The plate may be rusted open, jammed by debris, or misaligned from a chimney shift. This is the symptom that gets Pottstown homeowners calling fastest - and it’s the one that tells you the repair can’t wait.
• You see rust flakes or water staining on the damper plate from below. Surface rust advances to pitting, and pitted metal never seals. Our camera inspection shows how far the corrosion has reached into the frame rails.

Replacement Cost & What’s Included

What drives the range: accessibility (how much of the smoke chamber we need to reach), whether the frame is rusted into the masonry, and whether you want a basic galvanized replacement or a stainless unit rated for twenty-plus years. Every estimate includes the Level-2 camera inspection and photo report - you see what we see before any work starts. Our 90-Day Done Right Promise covers the installation in writing, no arguing. The number on the estimate is the number on the invoice.

DIY or Call Us?

You can safely check whether the handle moves freely and whether daylight shows around the plate when it’s supposedly closed. What you should not do: try to force a rusted pivot pin with penetrating oil and a hammer, or attempt to remove a damper plate seated in high-temperature masonry cement without knowing what’s above it. The plate can drop into the flue. The smoke chamber above it is not designed to hold your weight if you climb up to retrieve it.
