Most Kirkland homeowners discover their Famco damper has failed on the first cold morning when smoke rolls back into the living room, or they notice the handle spins freely without catching. In older homes near Juanita Beach and the Finn Hill ridge, we’ve found dampers frozen shut after decades of disuse, often hiding Class III glazed creosote behind them.

Which Famco Models This Applies To

Famco manufactured throat dampers in several series common to Kirkland homes built between 1965 and 1995. The most frequent are the cast-iron C-series with a 5/16-inch spindle shaft, and the lighter stamped-steel S-series used in prefab fireplace systems. The critical compatibility check is the throat opening width: C-series plates come in 30-inch, 32-inch, and 36-inch widths, while S-series plates max out at 30 inches. Measure the inside width of the damper frame, not the fireplace opening.

The model stamp is usually visible on the handle bracket or the frame edge if corrosion hasn’t eaten it away. If the stamp is gone, we match by spindle diameter and frame depth. For the C-series, we stock OEM-style cast plates from Famco’s current production line. For discontinued S-series units, we use a quality aftermarket equivalent from Gelco with a stainless steel frame that outlasts the original stamped steel in Kirkland’s wet winters. We are an independent service provider with no affiliation to Famco.

Signs Your Famco Damper Repair Is Failing

• The handle turns but the plate doesn’t move. The spindle-to-plate connection has sheared, usually from corrosion at the pivot pin. This is the most common failure we see in Kirkland’s marine climate, where decades of moist air rust the internal mechanism while the exterior handle still looks fine.
• The plate is stuck fully open or fully closed. Creosote buildup has cemented the edges, or the frame has warped from heat cycling. In homes near Lake Washington with south-facing chimneys, thermal expansion from summer sun on dark flue tiles accelerates this warping.
• Smoke spills into the room on light wind days. The plate no longer seats flush against the frame, creating a gap that reverse airflow exploits. This often means the plate edge has eroded or the frame has cracked at the corners.
• You feel cold drafts even when the fireplace is not in use. The damper seal has failed completely, and you’re heating the outdoors. In Kirkland’s older homes with original Famco dampers, this can add $150-$300 to annual heating bills.
• The handle is missing or the bracket is broken off. Someone forced it. The remaining stub is often seized inside the frame, making extraction a job for proper tools rather than pliers and hope.

Replacement Cost & What’s Included

What drives the range: accessibility (how much of the smoke chamber we need to work through), whether the frame bolts are seized, and whether creosote removal is required before the new plate will seat. Every quote is itemized in writing before work starts, per Haven Standard Clause 1. The installed price includes the NFPA 211 Level 2 camera inspection, a documented photo record under Haven Standard Clause 4, and our 365-Day Done Right Promise. Parts are sourced through Haven’s buying network to keep customer prices honest.

DIY or Call Us?

There’s a safe middle ground. You can verify the model stamp, measure the throat opening, and check whether the handle turns freely. What you should not do: reach up past the damper into the flue without proper PPE, attempt to force a seized spindle with power tools, or work on the smoke chamber without a stable platform. The plate sits directly below the flue liner; disturbing accumulated creosote can release respirable particles, and a slip from an improvised ladder in a firebox sends people to EvergreenHealth more often than you’d think.

We carry Famco-compatible dampers, Gelco stainless frames, and the extraction tools for seized spindles on every Kirkland truck. Call (425) 642-3485 for a written estimate with no dispatch fee.
