Famco Damper Repair: The Fort Worth Owner’s Guide

Famco damper repair in Fort Worth typically runs $280-$520 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock Famco-compatible damper parts on our trucks and can usually match your model same-day. Most Fort Worth homeowners discover the problem on the first cold snap, when they open the damper and it hangs crooked, won’t seal, or drops rust into the firebox.

Which Famco Models This Applies To

Famco has manufactured throat dampers and top-sealing dampers under several series names over the years. The most common we encounter in Fort Worth homes are the Famco cast-iron throat dampers (typically 30″, 32″, and 36″ widths) and the lighter stamped-steel models found in prefab fireplaces from the 1990s and 2000s. The critical compatibility gotcha: Famco throat dampers built before 2004 used a 5/16″ pivot rod, while post-2004 models switched to 3/8″. Mix the hardware and the plate binds or cracks within a season.

To identify your model, look for a stamped code on the damper frame’s right-hand side, visible from the firebox with a flashlight. If the stamp’s worn off, we measure the throat opening width, the pivot rod diameter, and the frame depth. For OEM Famco parts, we source through Haven’s buying network; for older or discontinued models, we spec equivalent aftermarket dampers from Gelco or Olympia Chimney that match the original dimensions without the OEM markup. Corrine Halstead keeps a cross-reference chart in every truck for the discontinued Famco 400-series - we’ve replaced enough of them in Mistletoe Heights and Berkeley Place to know the equivalents by heart.

Signs Your Famco Damper Repair Is Failing

• The plate won’t open or close fully. Pivot rod corrosion is the usual cause. Fort Worth’s humidity swings, especially in spring and fall, rust the rod where it passes through the frame. Once seized, forcing the handle bends the linkage and turns a $320 repair into a full assembly replacement.
• You feel a draft even when the damper is “closed.” The cast-iron plate warps over years of heat cycling. A warped Famco plate leaves a 1/4″ gap that pulls conditioned air up the flue year-round. In Texas summers, that’s attic-hot air entering your living space; in winter, it’s your heat money climbing the chimney.
• Rust flakes or grit fall into the firebox when you operate the handle. This means the plate edge or frame seat is actively corroding. The debris isn’t just messy - it prevents the plate from seating flat, and sharp rust edges accelerate wear on the frame.
• The handle is loose or the linkage rattles. The Famco linkage system uses a cotter pin and clevis connection that loosens over time. A rattling handle often means the pin is walking out; if it drops free, the plate can fall fully open or closed with no way to control it from the fireplace.
• Smoke spills into the room on startup. A damper that doesn’t open fully restricts draft. With Famco throat dampers, the plate can appear open while still blocking 30% of the throat area. The smoke chamber can’t develop enough negative pressure, and you get a faceful of particulates.

Replacement Cost & What’s Included

What drives the range: access difficulty (firebox depth, smoke chamber shape), whether the frame is rust-welded to the lintel, and whether we need to remove firebrick to extract the old unit. Every quote is written before work starts - Haven Standard Clause 1 - with the part number, labor hours, and warranty term listed. The 365-Day Done Right Promise covers the installation; parts carry manufacturer warranty. We include a camera-scan inspection of the flue above the damper on every job - Clause 4 of the Haven Standard - because a failing damper often hides creosote buildup or liner damage that needs documenting.

DIY or Call Us?

Here’s where honesty matters. A homeowner can safely check whether the damper handle moves freely and whether rust debris is present. You can also verify the stamped model number with a flashlight and a phone photo. What you should not attempt: extracting a rust-seized pivot rod, removing firebrick to access a frame, or operating on a damper assembly while standing on a fireplace tool set. The plate weighs 15-25 pounds of cast iron; if the frame lets go while you’re working, it drops on your hands or into the firebox with enough force to crack brick.

We carry Famco-compatible plates, rods, bushings, and full assemblies on our trucks. Most replacements in Fort Worth take 90 minutes to two hours. Call (682) 499-2712 and we’ll confirm your model match before we dispatch - no diagnostic fee for the phone check, and the written price arrives before anyone enters your home.
