Famco Damper Repair: The Long Beach Owner’s Guide

Famco damper repair in Long Beach typically runs $280-$520 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock Famco-compatible parts on our trucks and can usually complete the swap in a single visit. Most Long Beach homeowners discover the problem when smoke rolls back into the living room or they feel a cold downdraft even with the damper supposedly closed.

Which Famco Models This Applies To

Famco has produced several damper lines over the years, and the part you need depends on when your fireplace was built and what throat configuration you’re working with. The Famco SD series (single-blade, rectangular throat) and the older FD line (double-blade, found in many 1960s-1980s Long Beach tract homes) are the two we see most often. The SD-8 through SD-12 cover throat widths from 8 to 12 inches; the FD-30 and FD-36 handle the wider openings common in the ranch-style homes near Bixby Knolls.

Here’s the compatibility gotcha: Famco changed the pivot pin diameter on SD-series dampers manufactured after 2004. The post-2004 pins are 3/8-inch; pre-2004 pins are 5/16-inch. Drop the wrong replacement plate into an older frame and the pin holes wallow out in two seasons. We measure throat width, pin diameter, and frame depth before ordering anything. That’s why we carry both OEM Famco plates and quality aftermarket equivalents from Copperfield on the truck - the aftermarket pins are hardened 4130 steel, which holds up better against the salt-air corrosion we see in Long Beach homes within a mile of the water.

Check the stamped model number on the damper frame, usually visible from the firebox with a flashlight. If it’s rusted over, we can pull it during the camera inspection and read it clean.

Signs Your Famco Damper Repair Is Failing

• Smoke back-puffing on startup. The plate isn’t seating squarely in the frame, usually because the hinge pin has corroded or the frame itself has warped from heat cycling. In Long Beach, salt air accelerates this - we’ve replaced dampers in oceanfront homes that were only eight years old.
• Cold downdraft when the fireplace isn’t in use. The plate gasket has compressed or the metal has cracked at the weld seam. A damper that won’t seal is essentially an 8-inch hole in your roof dumping conditioned air.
• Rattling or grinding when you operate the handle. The linkage has slipped out of true or the worm gear in the rotary control has stripped. Famco rotary controls use a 5/16-inch square drive; if the socket rounds off, the handle spins free without moving the plate.
• The handle moves but the plate doesn’t. The cotter pin connecting the linkage to the plate has sheared, or the plate itself has dropped a pivot pin. This is the failure that sends homeowners scrambling because the fireplace becomes unusable.
• Visible rust flakes or orange staining on the firebrick. The damper frame is shedding oxidation from the underside. In humid months near the Long Beach shore, this can progress from surface rust to through-hole corrosion in a single season.

Replacement Cost & What’s Included

The range depends on three things: whether we can reuse the existing frame, whether the smoke chamber needs refractory patching to seat a new frame properly, and whether the fireplace is on an exterior wall with limited access. Every quote is written before work starts - Clause 1 of the Haven Standard. The price includes the NFPA 211 Level 2 camera inspection, the documented photo record under Clause 4, and a 365-Day Done Right Promise on the installation. We source Famco and Famco-compatible parts through Haven’s buying network; we don’t markup hardware separately from labor.

DIY or Call Us?

There’s one thing you can safely check yourself: whether the handle linkage has simply slipped its cotter pin. Shine a flashlight up the throat and look for the pin at the junction where the control arm meets the plate. If it’s missing, a replacement pin costs about $2 at any hardware store. That’s the end of the safe DIY list.

Everything else involves working at height over the firebox, handling a steel plate that can weigh 15-25 pounds in an awkward overhead position, and setting the frame square in mortar so the plate seals properly. A misaligned frame leaks smoke and carbon monoxide. We’ve been called to Long Beach homes where a homeowner’s self-installed damper plate dropped six months later because the frame wasn’t bedded in refractory cement. The camera doesn’t lie, and neither does the price sheet - call (424) 401-5585 and we’ll show you exactly what failed before you decide.
