Famco Damper Repair: The Cherry Hill Owner’s Guide

Famco damper repair in Cherry Hill typically runs $280-$520 installed, and we stock the common Famco throat damper plates, frames, and pivot hardware on our trucks for same-day completion. Most Cherry Hill homeowners discover the problem the first cold snap in late October, when they open the damper and it hangs crooked, rattles in the flue, or will not seat tight enough to stop the downdraft. Russell Haines and our crew have replaced Famco dampers in colonials from Barclay Farm to newer builds off Route 70, and the failure pattern is nearly always the same: decades of heat cycling in South Jersey’s freeze-thaw winters eventually cracks the cast plate or wears the pivot pin slots oval.

Which Famco Models This Applies To

Famco built throat dampers in several widths from 24 inches to 48 inches, with the 30-inch and 36-inch plates showing up most often in Cherry Hill’s 1960s-1980s colonials and split-levels. The critical measurement is the inside width of the flue throat, not the plate itself, because Famco frames were built to tuck into the mortar bed between courses. If your damper still has the original tag, look for a stamped model number starting with FD- or a date code in the 1970s-1990s range.

We are an independent service provider, not affiliated with Famco. For units where the original plate is discontinued, we source professional-grade aftermarket equivalents from Copperfield and Olympia Chimney that match the Famco pivot geometry and stainless specifications. The decision between OEM and aftermarket comes down to frame condition: if the frame ears are cracked or the pivot pin holes are wallowed out, replacing the entire assembly with a new frame and plate is the sound repair. If the frame is solid, a matched plate alone will seat properly and cost less.

One compatibility gotcha we see in Cherry Hill: some Famco units from the 1980s used a left-hand pivot orientation that newer universal plates do not accommodate without shimming. We measure on-site before pulling parts from the truck.

Signs Your Famco Damper Repair Is Failing

• The handle turns but the plate does not move. The linkage between the handle spindle and the plate has separated, or the pivot pin has sheared. This is common after 25-plus years of seasonal use in Cherry Hill’s climate, where summer humidity swells the mechanism and winter contraction stresses the pin.
• You feel cold air dropping down the flue even when the damper is “closed.” The cast plate has warped or cracked along its edge, leaving a gap that draws conditioned air out of the house year-round. In Barclay Farm homes with original Famco units, we regularly see hairline cracks that widen after the first hard freeze.
• The plate chatters or vibrates when the wind blows. The pivot hardware has worn enough to let the plate rock in the frame. Left alone, this wears the frame ears and turns a plate replacement into a full assembly job.
• Rust flakes fall onto the firebox floor. The original mild-steel components have corroded through. Cherry Hill’s position in the pine barrens means slightly acidic soil moisture can accelerate rust in crawl-space and slab-on-grade installations where flue condensation collects.
• The damper sticks fully open and will not close. Creosote buildup has glued the plate to the frame, or the handle mechanism has seized. This is the condition that costs the most in lost heat, and it is also the one most likely to hide cracked frame ears you cannot see from below.

Replacement Cost & What’s Included

For Cherry Hill homeowners, Famco damper replacement breaks down as follows:

The spread depends on flue access (whether we need to remove the smoke shelf to extract the frame), the condition of surrounding firebrick, and whether the original fasteners have corroded in place. Our Level-2 camera inspection is included before we quote: photos you can see, a plain-English verdict. No work proceeds without your approval of the exact number on the estimate, and that number is the number on the invoice. Every damper repair is covered by our 90-Day Done Right Promise, in writing, no arguing.

DIY or Call Us?

A homeowner can safely check three things from the firebox: whether the handle turns freely, whether the plate visibly moves when the handle operates, and whether daylight shows around the plate edge when closed. Use a flashlight and a mirror. Do not reach up into the throat.

What goes wrong with DIY: the plate weighs 15-20 pounds of brittle cast iron, and it sits above your head in a narrow flue. Dropping it damages the smoke shelf or liner. More seriously, many Cherry Hill homes with original Famco dampers also have aging clay flue liners that crack if bumped. The pivot pins are under spring tension on some models, and a slipped wrench can send hardware into the flue where it lodges against the liner wall. We do not recommend homeowner removal.
