Famco Damper Repair: The Hempstead Owner’s Guide

Famco damper repair in Hempstead typically runs $240 – $420 installed, depending on whether we’re replacing the damper plate, the cable assembly, or the full frame. We keep the most common Famco replacement parts on the truck, so most repairs are finished in a single visit. The way homeowners usually find us is by noticing the damper won’t close all the way, or the handle spins without resistance, or there’s a draft that wasn’t there last winter. Famco dampers are solid pieces of equipment, but the moving parts wear out. Here’s what that looks like and what it costs to fix it right.

Which Famco Models This Applies To

Famco makes a few distinct damper lines, and the repair path depends on which one you have. The most common units we see in Hempstead homes are the LD (Lyemance-style top-sealing), the SD (standard throat-mount with a cast frame), and the HD series for larger masonry fireplaces. The model number is usually stamped on the frame or on a small metal tag riveted near the hinge point. If the tag is gone, we identify it by measuring the throat opening width and the mounting hole pattern. Famco plates are measured in even-inch increments, so a 24-inch plate is actually 24 inches of blade, not the rough opening. That’s a common gotcha when homeowners order the wrong size online.

On the OEM-versus-aftermarket question: for Famco specifically, we use OEM components whenever the frame is still sound. The hinge geometry and cable lengths are exact, and a mismatched aftermarket plate will either bind or leave gaps. When the original part is discontinued or backordered, we’ll use a quality aftermarket match and tell you before we install it, with the price adjusted accordingly. No surprises.

Signs Your Famco Damper Repair Is Failing

• The handle spins freely or feels loose. This usually means the cable has snapped at the pulley or the set screw on the handle hub backed off. Either way, the damper plate is no longer connected to the control.
• The damper won’t seat fully closed. Over years of heating and cooling, the plate warps slightly or the hinge ears wear oval. You’ll feel cold air dropping down the flue even when the handle is in the closed position.
• Rust flakes or debris on the smoke shelf. Famco plates and frames are steel, and Hempstead humidity plus flue condensation accelerates corrosion. Surface rust is cosmetic. Pitting or flaking through the metal is structural.
• A grinding or scraping sound when opening or closing. That’s the blade edge dragging against scale buildup or a bent frame corner. Forcing it only bends the mechanism further.
• Visible light or daylight around the plate edges when closed. Put a flashlight in the fireplace at night and look up from outside or from below. Gaps around a closed damper mean the seal is gone and heated air is escaping continuously.

Replacement Cost & What’s Included

We price Famco damper repair by the part and the labor, and we put that price in writing before any work starts. In Hempstead, a simple cable replacement runs about $240 – $290. A new damper plate with existing frame typically lands in the $300 – $360 range. A full frame-and-plate replacement, which means removing and resetting the old frame in the throat, runs $380 – $420 or slightly more for oversized openings. That includes removal of the failed component, cleaning the mounting surface, installing the new part, and a full operational test to confirm the seal closes tight. Every repair carries our 365-Day Done Right Promise in writing: if the damper fails within one year of service, we return at no charge to make it right. That’s part of The Garrison Standard every Flint Chimney Sweep job follows.

DIY or Call Us?

You can safely check a few things on your own. Look for a loose set screw at the handle hub, check that the cable hasn’t simply slipped off a pulley, and shine a light to see if the plate is seating flat. That tells you whether it’s a mechanical failure or a wear problem. What you should not do is try to remove or replace the damper frame yourself. The frame sits in the throat of the chimney, and if it lets go while you’re working on it, you’re dealing with a heavy steel plate and sharp edges in a confined space. We’ve also repaired more than a few DIY jobs where the new plate was torqued down against warped framing and bound up within a month. Call (516) 559-6922 and we’ll diagnose it properly.
