Famco Damper Repair Nationwide

Famco Damper Repair: The Long Beach Owner’s Guide

If your Famco damper won’t close, won’t stay open, or has come loose from its mounting bracket, we repair and replace them in Long Beach every week. A typical Famco damper repair or replacement runs $275 to $550 installed, and in most cases we can complete the swap in a single visit. The part alone is rarely the issue. What fails first is almost always the cast-iron frame cracking at a stress point, or the pivot pin shearing from years of heat cycling plus salt air from the Long Beach harbor.

You usually find out the hard way: a cold draft in February, ash smell in the living room after a fire, or a damper that freezes in the half-open position and won’t respond to the handle. That’s the moment to get it fixed, not just for comfort but because a damper that won’t close is a standing chimney leak.

Which Famco Models This Applies To

Flint Chimney Co Long Beach repairs and replaces the two Famco damper lines most common in Southern California homes: the cast-iron throat damper (rectangular, installed just above the firebox) and the top-sealing damper (round or square, mounted at the flue crown). Within those two families, the part you need depends on the width of your throat opening or the inside diameter of your flue tile. We carry 24″, 30″, and 36″ throat plates on the truck, plus top-seal adapters for 6″ through 13″ round flues and 8×8″ through 13×13″ square flues.

Here’s the gotcha most owners hit when they buy a Famco damper online: the mounting tabs on older cast-iron frames from the 1990s don’t match the hole spacing on current production. It’s a quarter-inch difference on some models, and if you don’t drill new anchor holes in the throat lintel, the frame will rock and fail within a season. We check that before we order anything. OEM Famco parts are good, but for top-sealing dampers we often specify aftermarket stainless equivalents from Gelco or Copperfield when the customer wants better corrosion resistance near the coast. Cast-iron throat dampers, we stick with Famco or an identical-pattern replacement.

Flint Chimney Co Long Beach is an independent service provider. We are not affiliated with Famco, but we stock and install Famco-compatible parts every week and know which versions work in Long Beach’s specific chimney configurations, from Belmont Heights Craftsmans to Shannon Park ranches.

Signs Your Famco Damper Repair Is Failing

• The handle spins freely with no resistance. This means the pivot pin or the linkage bar has broken. On top-sealing dampers, it’s usually the cable snapping inside the conduit. The damper is stuck open and heated air is escaping 24/7.
• The damper plate won’t seat flat when closed. You can see a quarter-inch gap even with the handle locked. This is typically a warped cast-iron plate or a frame that’s shifted out of square. The gap is a direct chimney draft path.
• You hear metal-on-metal scraping when operating the handle. The plate is dragging against the frame, which means the pivot bushings have worn oval. Continuing to force it will snap the pivot clean off.
• Ash and soot fall into the firebox on windy days. That’s the damper not seating, but the root cause is often a cracked frame corner that opens wider when wind pushes against the flue.
• Rust flakes collect under the damper plate. In Long Beach, the salt air accelerates frame corrosion on cast-iron units within 10 to 15 years. Once the frame legs rust through, the damper cannot be repaired; it has to be replaced.

Replacement Cost & What’s Included

In Long Beach, expect $275 to $550 installed for a Famco damper repair or replacement, depending on which of the two paths your chimney needs:

The spread comes down to access: a first-floor fireplace with a standard throat gives us under an hour of labor, while a second-story top-seal replacement means ladder work plus crown weatherproofing. Every quote is written down before we touch the chimney, and the number we quote is the number on the invoice. We include the removal of the failed part, replacement of any questionable anchor hardware, and a smoke test to confirm the damper actually seals. Every repair carries our 365-Day Done Right Promise in writing, and if a covered repair fails within that year, we return at no charge.

DIY or Call Us?

Here’s the honest split. You can safely diagnose the problem from inside your home: open and close the handle, look for visible cracks in the frame, check if the plate seats flat. That tells you whether you’re dealing with a broken pivot or a failed frame. What you shouldn’t do is attempt a repair on a cast-iron throat damper yourself. The frame is anchored overhead with expansion bolts, the plate is heavy, and a spring-assisted or counterweighted linkage under tension can snap fingers when released incorrectly. It’s not worth a trip to urgent care.

The easiest move is to call (562) 317-7262 and describe what you’re seeing. We’ll give you a ballpark over the phone, then set a visit window that works. Hank Delano or one of the crew will show up, confirm the diagnosis in person, and put the price in writing before any work begins. “Clean flue, honest report – that’s the whole job.”
