Olympia Chimney Damper Repair: The Annapolis Owner’s Guide
If you have an Olympia Chimney damper that won’t open, won’t close, or is rattling in the wind, we stock the common repair parts and can usually get it working again the same visit. Installed repair in Annapolis typically runs $145 to $395 depending on whether it’s the handle assembly, the damper plate, or the frame that’s failed. Most folks discover the problem the first cold night of the year, when the fireplace won’t draw or a draft starts pulling heat up the flue even with the damper shut.

We’ve been into enough Olympia Chimney dampers to know the failure points before we even climb on the roof. The cable or rod mechanism corrodes, the pivot pins wear out, or the plate itself warps from years of heat and Annapolis humidity. Wendell Pike and his crew keep the common Olympia Chimney replacement parts on the truck, so we don’t have to leave you with a tarp over the chimney while we order pieces.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes a range of dampers, but the ones we see most often in Annapolis homes are the cast-iron throat dampers paired with masonry fireplaces and the top-sealing dampers used with their chimney cap systems. The throat dampers are the simple ones, a cast plate on a pivot with a handle or cable. The top-sealing dampers are more involved, a spring-loaded cap that sits at the flue top and seals with a rubber gasket.
The compatibility gotcha with Olympia Chimney is the pivot pin spacing. Throat dampers come in widths from 24 to 48 inches, but the pin-to-pin measurement on the frame is what matters, not the overall plate width. Measure the opening left-to-right and front-to-back, then check the pin spacing before you order anything. Olympia’s top-sealing dampers are sized by flue tile dimensions, and they’re sold in standard square and rectangular sizes. If the flue is an oddball, you’ll need the adjustable frame version.
For most repairs, OEM Olympia parts fit without fuss, and that’s what we prefer when the damper frame itself is in good shape. If the frame is shot, a quality aftermarket cast-iron damper from a brand like Famco or Copperfield will do the same job, and we stock those too. We’re an independent service provider, not tied to Olympia Chimney, so our recommendation is based on what works, not what the catalog pushes.
Signs Your Olympia Chimney Damper Repair Is Failing
- You can’t move the handle, or the cable feels loose. The pivot pin has rusted or the cable end has pulled free from the damper plate. This is the most common failure, especially in older Annapolis homes where the damper hasn’t been touched in years.
- A cold draft comes down the chimney when the damper is closed. The plate is warped or the seat has crumbled, leaving gaps the damper can’t seal. In a Maryland winter, that’s heat going straight out the top.
- The fireplace is smoky even on a normal fire. The damper plate isn’t opening far enough, often because a corroded pivot is binding. The fire can’t breathe, so smoke rolls back into the room.
- You hear rattling or banging when the wind blows. A loose damper plate or worn pivot lets the wind chatter it. Annapolis gets enough wind off the Chesapeake that this is a frequent complaint.
- Water or soot streaks appear on the firebox walls below the damper. A failing top-sealing damper gasket lets rain through, which carries soot down with it. That moisture also accelerates the damage.
Replacement Cost & What’s Included
Damper repair for an Olympia Chimney unit in Annapolis generally runs $145 to $395 installed, depending on what’s actually wrong. A stuck pivot pin with a replacement handle is on the low end. A warped damper plate or a failed top-sealing damper gasket runs higher because the parts cost more and the job takes longer. Replacing the entire frame is the expensive end, and sometimes that’s the only honest fix if the metal has cracked through.

The number we quote on the phone is the number on the invoice. No surprises after the work is done. That’s how we’ve operated since 1999, and it’s why folks around Annapolis keep our number. Every replacement part we install is backed by the 90-Day Done Right Promise: if the fix doesn’t hold, one call brings us back at no charge. We also knock $40 off any repair over $200, and seniors and veterans get 10% off always. If you’ve got a written estimate from anyone else, bring it in and we’ll review it for free before you decide.
DIY or Call Us?
You can safely diagnose a lot from the firebox. Does the handle move? Does the plate look straight from underneath? Does light show around the edges when the damper is closed? Those checks take five minutes and don’t require ladders or tools. Knowing the answer helps us quote the repair over the phone.
The part where DIY goes wrong is the install. Throat damper plates are heavy cast iron, and they sit inside a tight space where a slip can mean cracked tile or a sliced hand. Top-sealing dampers require getting on the roof, cutting away the old cap, sealing the new frame, and adjusting spring tension. That’s not a Saturday project. If it doesn’t need doing, I’ll tell you that too. But if it does, call us at (240) 851-3653 and we’ll handle it right the first time. Wendell and his crew work across Annapolis every week, and we’ve been in some of the oldest flues in the Historic District.
FAQs
A cast-iron throat damper in Annapolis usually lasts 20 to 30 years before the pivot pin or plate gives out, while top-sealing dampers often need a gasket replacement around year 10, because the heat and moisture cycle takes a toll on rubber. Annual cleaning and keeping a chimney cap above it extends the life. Call (240) 851-3653 for an honest assessment instead of guessing.
It depends on what’s failed: a worn pivot pin or cable can usually be repaired with the existing damper plate, but a cracked or heavily warped plate means replacement. We’ll show you the damage before we touch anything, so you’ll know exactly why we’re recommending what we are. Call (240) 851-3653 to schedule a look.
Most Olympia Chimney damper repairs take 45 minutes to two hours, depending on whether it’s a simple pin and handle swap or a full frame replacement. Top-sealing damper installs run a bit longer because of the roof work and sealant cure time. If we have the part on the truck, which we usually do, it’s a single visit.
We keep the common Olympia Chimney damper plates, pins, cables, and gaskets on the truck, along with compatible aftermarket options from Famco, Copperfield, DuraFlex, HeatShield, and Gelco. If you have an unusual size, we can order it and have it installed within a few days. Call (240) 851-3653 and tell us your damper dimensions; we’ll quote it before we leave the shop.
