Olympia Chimney Damper Repair: The Littleton Owner’s Guide

Olympia Chimney damper repair in Littleton typically runs $280-$520 installed, depending on whether the throat plate, frame, or full assembly needs replacement. We stock common Olympia Chimney damper configurations on our trucks and can usually complete the swap in a single visit once the model is verified. The most frequent call we get is from homeowners who’ve finally noticed the cold draft or smell of old fireplace ash they can’t trace to anything else.

Most owners in Littleton figure out their damper has failed in one of two ways: they light a fire and smoke pushes into the living room, or they feel a persistent downdraft even with the damper “closed.” In older homes around Columbine Knolls and the original Ken Caryl ranch properties, we’ve seen Olympia Chimney dampers that were installed in the 1990s and have simply worn through their pivot points after thousands of open-close cycles through dry Front Range winters.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactured throat dampers under several product lines, and the critical detail is whether your fireplace has a standard rectangular throat or the wider builder-grade opening common in 1980s-2000s Colorado tract homes. The cast-iron throat assemblies marked “Olympia” or “Olympia Chimney” typically carry a model stamp on the frame’s left-hand side, visible from the firebox with a flashlight. If the stamp is corroded, measure the throat opening width and depth - we cross-reference against Olympia’s original spec sheets, which listed standard sizes at 30″, 36″, and 42″ widths with 6″ or 8″ depth frames.

We source replacement dampers through Haven’s buying network from Olympia Chimney, Gelco, and Famco. For most Littleton homes, a quality aftermarket damper from Gelco or Famco matches the original Olympia spec at lower cost and carries the same 10-year warranty. We only recommend OEM Olympia parts when the original frame is intact and the homeowner specifically wants matched components, or when the fireplace has an unusual throat geometry we can’t verify without pulling the existing assembly.

Signs Your Olympia Chimney Damper Repair Is Failing

• Cold air pours down the flue even when the damper is shut. The cast-iron plate has warped or the metal sealing edge has eroded, leaving a gap that lets outside air bypass the closure. In Littleton’s spring wind patterns, this can drop your living room temperature several degrees overnight.
• You smell old ash or creosote between fires. A damper that doesn’t seat fully allows odor-laden air from the smoke chamber to drift back into the house. The smell is usually strongest on humid days or when barometric pressure drops ahead of a Front Range storm.
• The handle or chain moves loosely without engaging the plate. The pivot pin has sheared or the linkage has corroded through. We see this often on Olympia dampers installed before 2005, where the original steel pivot hardware wasn’t stainless and succumbed to condensation cycling.
• Smoke spills into the room when you start a fire. The damper may be stuck partially closed, or the plate has dropped out of alignment and blocks half the flue opening. Either condition chokes draft and pushes combustion gases backward.
• Visible rust flakes or cracking on the damper plate itself. Cast iron fatigues thermally - each heating cycle expands and contracts the metal. After 15-20 years of Colorado’s wide temperature swings, micro-cracks propagate until the plate fractures or the sealing surface degrades.

Replacement Cost & What’s Included

The range depends on three things: whether the existing frame can be reused, how accessible the throat is from the firebox, and whether the smoke chamber needs refractory repair where the old damper frame was anchored. We deliver a written price before any work starts - Haven Standard Clause 1 - and that price includes the part, labor, a new handle or chain assembly, and a camera-scan photo record of the completed installation. Every damper replacement carries our 365-Day Done Right Promise.

DIY or Call Us?

There’s one thing a homeowner can safely check: open the damper fully, shine a flashlight up the flue, and look for obvious cracks in the plate or a detached handle linkage. If you see either, stop there. The rest of the job involves working at height inside the firebox, handling a 15-25 pound cast-iron assembly overhead, and seating a new frame with proper clearances to combustible framing - errors here create chimney fire risk and can void homeowner’s insurance.

We’ve been called to Littleton homes where a DIY damper swap left the throat plate misaligned by half an inch, which doesn’t sound like much until you realize it’s the difference between a sealed flue and a carbon monoxide pathway. The camera doesn’t have an opinion - it just shows you what’s there. Call (720) 439-4666 and we’ll verify the model, quote the repair in writing, and handle the heavy work.
