Olympia Chimney Damper Repair: The Easton Owner’s Guide

Olympia Chimney damper repair in Easton typically runs $280-$520 installed, depending on whether the throat plate, frame, or full assembly needs replacement. We stock common Olympia Chimney damper sizes on our trucks and can usually match your model same-day. Most Easton homeowners notice the problem first as a draft they can’t shut off or a handle that spins without catching.

The damper sits right above the firebox, exposed to every temperature swing from zero-degree Easton winters to 500-degree fires. Olympia Chimney builds theirs with stainless steel frames and cast-aluminum plates that hold up well, but the linkage, pivot pins, and tension springs fatigue after years of cycling. When the plate warps or the frame cracks, you’re losing heated air up the flue even when the fireplace is cold. Russell Haines and our crew have replaced these in colonials along the Delaware Canal, in ranch homes near College Hill, and everywhere between. We’ve learned which Olympia Chimney series share parts and which need exact OEM matching.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures several damper lines, and the part you need depends on when your fireplace was built and which throat dimension you’ve got. The most common in Easton homes are the standard throat dampers for 24″, 30″, and 36″ Rumford-style openings, plus the top-sealing damper assemblies used on some newer prefabricated chimney systems. Check the stamped model number on the damper frame itself, usually visible with a flashlight looking up from the firebox. It’s often on a small metal tag near the handle pivot.

Here’s where owners get tripped up: Olympia Chimney’s OD-series throat dampers from the 1990s and early 2000s used a 5/16″ pivot pin, while current production runs 3/8″. The plates look identical from below. Measure the pin diameter before ordering, or you’ll have a part that almost fits. We carry both pin sizes and the corresponding bushings. For aftermarket equivalents, we source from Gelco and Famco, matching the stainless grade and frame gauge to Olympia Chimney spec. We don’t use hardware-store dampers that rust out in two Easton winters. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney.

Signs Your Olympia Chimney Damper Repair Is Failing

• The handle turns but the plate doesn’t move. The linkage between handle and plate has slipped or the pivot pin has sheared. This is the most common failure we see in Easton, especially in homes where the damper hasn’t been lubricated in years of seasonal use.
• You feel cold air falling from the fireplace even when it’s closed. The plate has warped or the frame has cracked, leaving a gap. Heated air escapes constantly. In older Easton homes with original oil heat, this was less noticeable; with today’s tighter construction and forced-air systems, the draft is unmistakable.
• The plate is stuck open and won’t budge. Creosote buildup has glued the plate to the frame, or rust has seized the pivot. This happens when a fireplace sits unused for a season or two, common in Easton’s spring and fall shoulder months.
• You see rust flakes or corrosion on the frame. Easton’s humidity cycles, especially in stone and brick chimneys that breathe, accelerate surface rust. Once pitting starts, the frame weakens and the plate won’t seat squarely.
• Smoke rolls into the room on startup. A partially open or warped plate disrupts the draw. The flue needs full open position to establish draft, then you throttle back. If the plate hangs crooked, you can’t control it precisely.

Replacement Cost & What’s Included

What drives the range: accessibility of the throat (some Easton homes have tight smoke chambers), whether the frame is reusable, and whether we need to remove firebrick to extract the old assembly. Our estimate includes the part, labor, and a Level-2 camera inspection of the flue above, with photos you can see and a plain-English verdict. No surprises on the bill. Everything we install carries our 90-Day Done Right Promise, in writing, no arguing.

DIY or Call Us?

There’s a safe middle ground here. You can verify the model number, measure your throat opening, and check whether the handle linkage is simply disconnected, a five-minute fix with a screwdriver. But the damper frame is seated in masonry, often above a smoke chamber with sloping walls. Removing it without disturbing the surrounding brick takes pry bars, patience, and knowing when to stop. The plate itself is heavy cast aluminum, awkward to maneuver in a tight throat without dropping it down the flue.

More importantly, once the old damper is out, you need to verify the flue liner above is intact before sealing it back up. We’ve found cracked liners in Easton homes where the owner removed the damper themselves, never looked up, and reinstalled over damaged terracotta. Our camera inspection catches what you can’t see from below. If the flue is clear and the mortar is sound, that’s all the good news you need. If it isn’t, we’ll show you the photo and explain what comes next, no upselling work you don’t need. Call (610) 756-1504 when you’re ready.
