Famco Damper Repair: The Marietta Owner’s Guide

Famco damper repair in Marietta typically runs $280-$520 installed, depending on whether the throat plate, frame, or full assembly needs replacement. We stock Famco-compatible parts on our trucks and can usually match your model same-day. Most Marietta homeowners discover the failure on the first cold snap in October or November, when they open the damper and it sticks, drops halfway, or the chain pulls free.

Corrine Halstead has spent the better part of two decades inspecting chimneys across Marietta, including plenty of afternoons working older homes along Whitlock Avenue where the masonry tells its own story. She’s seen enough Famco dampers to know which serial ranges have the welded-frame issue and which don’t. Camera first, quote second, work third - in that order, every time.

Which Famco Models This Applies To

Famco throat dampers break down into two main series you’ll find in Marietta homes: the older cast-iron C-series (roughly 1985-2008) and the lighter stamped-steel S-series that followed. The C-series carries a part number stamped on the right-side frame ear; the S-series hides its number under a riveted tag on the handle bracket. Both measure throat opening width and depth to the quarter-inch, not the nominal fireplace opening.

Here’s the compatibility gotcha: Famco changed their handle geometry in 2012. A post-2012 S-series damper plate will seat crooked in a pre-2012 frame because the pivot pin moved 3/8 inch. We’ve found this mismatch three times in East Cobb ranch homes where a previous owner swapped the plate alone. We carry both pin configurations and verify with a test fit before quoting.

OEM Famco parts are still produced through Copperfield’s distribution network, which is how we source them. Quality aftermarket equivalents from Gelco match the spec at roughly 15% less, though we default to OEM when the existing frame is cast iron - the thermal expansion rates differ enough to matter over a decade of Marietta freeze-thaw cycles.

Signs Your Famco Damper Repair Is Failing

• The handle pulls but the plate doesn’t lift. The linkage pin has sheared or the cotter clip has corroded. In Marietta’s humid summers, we’ve seen this on C-series dampers as young as twelve years old if the firebox sees frequent use.
• The plate drops open on its own after you close it. The counterweight has slipped or the torsion spring has lost tension. S-series springs fatigue faster than C-series weights, especially in homes that burn pine from North Georgia suppliers where creosote buildup adds load.
• You feel cold air dropping even when the damper is closed. The plate is warped or the frame seat has eroded. Cast-iron C-series frames crack at the rear corner from thermal shock; once the seat is no longer flat, no adjustment fixes it.
• The chain or handle is loose with no resistance. The connection to the linkage has broken. This is the one failure an owner can spot from the hearth without tools, but the repair still requires accessing the throat assembly.
• The damper binds and requires force to move. Creosote has glazed the pivot points or the frame has rust-swollen. Marietta’s pollen season deposits organic material that accelerates corrosion when mixed with condensation.

Replacement Cost & What’s Included

What drives the range: throat depth over 16 inches requires a custom-order plate (adds 3-5 days), cast-iron frame removal in tight fireboxes takes longer, and some Marietta homes built 1960-1985 have non-standard throat angles that need field modification. We quote in writing before work starts, per Haven Standard Clause 1. The 365-Day Done Right Promise covers labor and materials.

DIY or Call Us?

What you can safely check: verify the handle connection at the hearth, look for obvious debris on the plate from below, and confirm the chain isn’t simply detached. Use a flashlight, not your hand - the plate edge is sharp and the throat is dark.

Where DIY goes wrong: the counterweight on C-series dampers runs 8-12 pounds and sits in a narrow frame channel. Dropping it damages the firebox liner or your fingers. The pivot pins are under spring tension on S-series units. We’ve been called to three Marietta homes this year where a homeowner dislodged the pin and the plate jammed sideways in the throat, turning a $320 repair into a $680 frame replacement plus liner inspection.

We carry Famco-compatible plates, frames, and hardware on our trucks. Call (470) 288-2763 and we’ll confirm your model over the phone, or text a photo of the part number tag.
