The damper is the metal plate that seals your flue when the fireplace is not in use. When it fails, you’re losing heated air up the chimney all winter, or you’re fighting smoke rollback into the living room. In Queens, where many Famco dampers were installed in 1960s and 1970s brick two-families and pre-war co-ops, we see the same failure patterns every season. The plate corrodes where it meets the frame, the pivot pins seize from creosote hardening, or the handle linkage snaps from decades of cold-start cycling. Russell Haines and our crew have replaced hundreds of these across Astoria, Forest Hills, and the Woodhaven Boulevard corridor. If it’s wrong, we’ll say so. If we fix it, it stays fixed.

Which Famco Models This Applies To

Famco manufactured throat dampers in several series, and the part you need depends on the width of your flue opening and the handle style. The most common in Queens are the 8-inch, 10-inch, and 12-inch cast-iron throat plates with either a right-hand or left-hand pivot. The handle may be a simple poker-style lever or a rotary knob with a threaded rod.

To identify your model, look for a stamped part number on the damper frame, visible from the firebox with a flashlight. If the plate is rusted over the stamp, measure the throat opening width and the plate thickness. Famco OEM plates are 3/16-inch cast iron. Aftermarket equivalents from Gelco match this spec and carry the same 10-year warranty, at roughly 15% less cost. We stock both. The critical compatibility gotcha: Famco frames from the 1970s used a 5/8-inch pivot pin, while 1980s production switched to 1/2-inch. A mismatched pin diameter will seat poorly and jam within a season. We measure on-site before ordering.

Signs Your Famco Damper Repair Is Failing

• The handle moves but the plate does not. The pivot pins have seized inside the frame brackets, usually from creosote glazing or rust. In Queens, this accelerates when homeowners burn unseasoned softwood, which deposits acidic moisture on the iron.
• You feel a cold downdraft even with the damper “closed.” The plate has warped or the frame has corroded at the seat, leaving a gap. Heated air escapes continuously. We document this with a smoke pencil during our Level-2 inspection.
• The plate is visibly cracked or perforated. Cast iron fatigues after 40+ years of thermal cycling. A cracked plate cannot seal and may drop pieces into the firebox, a hazard you cannot see from below.
• Smoke spills into the room on startup. The damper is not opening fully, or it is stuck partially closed. This is not always the damper’s fault, but a seized Famco plate is the first thing we rule out.
• Rust flakes or grit fall when you operate the handle. The frame is deteriorating from the inside. In Queens basements and first-floor hearths with exterior exposure, we’ve seen frames so corroded that the plate drops free entirely.

Replacement Cost & What’s Included

What drives the range: accessibility of the firebox (some Queens row houses have shallow hearths that complicate extraction), whether the frame bolts have sheared off and need drilling out, and whether we use Famco-spec OEM or Gelco aftermarket. Labor includes removal, precise fitting of the new assembly, and operational testing. Every damper replacement includes our Level-2 camera inspection of the flue above, with photos you can see and a plain-English verdict on what else needs attention. The work is covered by our 90-Day Done Right Promise, in writing, no arguing. A square deal: no surprises on the bill.

DIY or Call Us?

There is one safe check a homeowner can make: with the firebox cold, open the damper fully and shine a flashlight upward to confirm the plate moves and seats. If you see daylight around the edges when closed, or if the handle spins freely, the repair is beyond hand tools.

We do not recommend DIY damper replacement. The plate and frame are heavy cast iron, positioned above your head in a confined space. Sheared frame bolts require drilling and extractor bits, often at awkward angles. More critically, disturbing the smoke shelf and firebox lining without knowing what you’re looking at can crack refractory panels or dislodge mortar, creating a fire path into the wall structure. We’ve been called to fix homeowner attempts that turned a $350 repair into a $1,400 rebuild. Our background-checked, uniformed technicians complete most jobs in a single visit, with no-hassle upfront pricing. Call (516) 531-6315 for a free estimate.
