Olympia Chimney Damper Repair: The Kennesaw Owner’s Guide

Olympia Chimney damper repair in Kennesaw typically runs $280-$450 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock common Olympia Chimney damper configurations on our trucks and can usually complete the repair on the first visit. Most Kennesaw homeowners notice the problem when smoke rolls back into the living room or they feel a cold downdraft even with the damper supposedly closed.

We see this call spike every October in neighborhoods around Kennesaw Mountain. The temperature drops, someone lights the first fire of the season, and the damper that stuck slightly open all summer suddenly won’t seal at all. Or it won’t open. Either way, the fireplace isn’t usable until it’s fixed.

Level Two Chimney Kennesaw is an independent service provider, not affiliated with Olympia Chimney. We source parts through Haven’s buying network, which includes Olympia Chimney, DuraFlex, HeatShield, and Gelco, specifically to keep customer prices honest.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures several damper series, and the right match depends on your flue size and installation era. The most common in Kennesaw homes are the 13″ x 13″ and 17″ x 17″ cast-iron throat dampers found on masonry fireplaces built between 1990 and 2015, and the smaller 8″ x 8″ and 10″ x 10″ units paired with their prefabricated chimney systems. The model number is stamped on the damper frame, visible from the firebox with a flashlight when the plate is fully open.

Here’s where owners get tripped up: Olympia Chimney changed their frame rail depth in 2008. A post-2008 damper plate dropped into a pre-2008 frame won’t seat properly, and you’ll still have a draft leak after replacement. We measure rail depth with a small gauge before ordering, because the difference is 3/16″ and it’s not visible to the eye.

For OEM versus aftermarket on Olympia Chimney dampers, we generally recommend OEM for the frame assembly, since the pivot pin placement is proprietary. The plate itself can often be sourced as a quality aftermarket equivalent from Gelco or Famco at lower cost, provided the dimensions and curvature match exactly. We stock both options on our trucks for the common sizes.

Signs Your Olympia Chimney Damper Repair Is Failing

• Cold air pours down the flue even when the damper is “closed.” The plate has warped or the frame has corroded at the seat, leaving a gap that widens as the metal heats and cools through Georgia’s humid seasons. We measure the leak with a smoke pencil during inspection.
• The handle moves but the plate doesn’t. The linkage between the rotary control and the pivot arm has separated, or the pivot pin has seized in its bracket. In older Olympia Chimney units, the cotter pin corrodes through and the arm drops free inside the frame.
• Smoke spills into the room when the fire is lit. The damper plate is stuck partially closed, restricting draft. This often happens after a season of disuse when rust or creosote has bonded the plate to the frame. Forcing the handle can snap the linkage.
• You hear metal grinding or scraping when operating the handle. The plate has shifted off-center in its frame, usually because the frame rails have spread from thermal cycling or because the mounting mortar has deteriorated. Continued operation will destroy the plate edges.
• Visible rust flakes or orange staining on the firebox floor. The damper frame is corroding from condensation that forms when warm, humid Kennesaw air meets the cooler flue surface. Once pitting reaches 1/16″ depth, the seat won’t seal regardless of plate condition.

Replacement Cost & What’s Included

What drives the range: accessibility of the damper frame through the smoke chamber, whether the frame is mortared into place or bolted (bolted units come out faster), and whether we find secondary issues like a deteriorated smoke shelf or Class III creosote that needs addressing. We write the full scope and price before any work starts, Clause 1 of the Haven Standard. Every repair carries our 365-Day Done Right Promise.

DIY or Call Us?

There’s a safe middle ground and a hard stop. What you can check: verify the handle isn’t just disconnected from the linkage (look up past the damper with a flashlight), confirm the plate isn’t blocked by a fallen chunk of refractory or a bird nest, and note the exact dimensions stamped on the frame if you can read them. That’s it.

What goes wrong with DIY damper replacement: the frame is mortared into the throat of the chimney, working overhead on a ladder inside a firebox, with your arms above your head and your face in the flue. The frame weighs 15-25 pounds of cast iron. Dropping it damages the smoke chamber lining or your skull. More commonly, owners install a plate that almost fits, don’t seat it fully, and spend a winter with a slow carbon monoxide leak into the home every time the fireplace operates. The damper is a combustion safety device, not a cabinet hinge. Call (678) 535-2204 and we’ll scope it with the camera first, show you what we found, and write down the price before you decide anything.
