Famco Damper Repair: The Plano Owner’s Guide

Famco damper repair in Plano 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 most replacements are finished in under two hours once the inspection confirms the fit. Most Plano homeowners realize their damper has failed when they feel a cold downdraft even with the fireplace “closed,” or when smoke pushes back into the room on the first fire of the season.

The damper sits directly above the firebox and seals the flue when the fireplace isn’t in use. In Plano’s clay-heavy soils and our wide temperature swings from August 105-degree days to January freezes below 20, that steel plate expands, contracts, and warps more than owners expect. A warped Famco damper plate won’t seat flat against the frame, and the conditioned air you’ve already paid for heads straight up the chimney year-round.

Corrine Halstead and our crew have replaced Famco dampers in Plano homes from the older ranch-style builds near Prestonwood to newer construction around Legacy West. The camera doesn’t guess. Neither do we.

Which Famco Models This Applies To

Famco manufactures throat dampers in several series, and the part you need depends on the width of your flue opening and how the original was mounted. The most common units we see in Plano are the Famco 8-inch through 13-inch galvanized throat dampers and the larger 30-inch to 42-inch masonry-frame assemblies found in pre-1990s homes. Check the stamped model number on the damper frame itself, usually visible from the firebox with a flashlight; if rust has eaten the stamp, measure the throat opening width and depth instead.

Here’s where compatibility gets specific: Famco’s older galvanized units used a 3/16-inch pivot rod, while current production runs 1/4-inch. A new plate ordered on Amazon that doesn’t match your pivot diameter will hang crooked and leak worse than the old one. We carry both pivot sizes on the truck, plus the aftermarket stainless equivalent from our Haven buying network that outlasts the original galvanized spec in Texas humidity.

We are an independent service provider, not affiliated with Famco. We source Famco-compatible parts through our Haven materials network alongside DuraFlex, HeatShield, and Gelco components, which keeps our pricing honest and our lead times short.

Signs Your Famco Damper Repair Is Failing

• Cold air falls down the chimney even when the damper is “closed.” The plate has warped or the frame has rusted out along the seat, creating gaps that let outside air bypass the seal. In Plano, this is most noticeable on north-facing chimneys after a cold front drops temperatures 30 degrees overnight.
• You smell smoke or burnt odor from the fireplace when it’s not in use. A damper that won’t fully close allows downdrafts to carry outside air, leaf debris, and occasional animal odor into your living space. The smell intensifies during our spring storm season when pressure changes are sharpest.
• The handle or chain moves, but the plate doesn’t pivot. The pivot rod has corroded through at the frame joint, or the plate has detached entirely and is sitting cockeyed in the throat. This is common on Famco units installed before 2005 that used the thinner 3/16-inch rod.
• Visible rust flakes or orange staining on the firebox floor. The galvanized coating has failed, usually at the weld points where water condenses during humid Plano summers. Once rust starts scaling, the plate thickness drops and the seal degrades faster.
• Smoke spills into the room when you light a fire. The damper may be stuck partially closed, or the plate may have dropped out of position entirely. This is the symptom that drives most calls, and it’s the one that tells you the failure is complete, not gradual.

Replacement Cost & What’s Included

The range depends on three things: whether we can reuse the existing frame, how accessible the throat is through your firebox opening, and whether the flue liner shows damage that needs documentation. We deliver a written price before any work starts, Clause 1 of the Haven Standard, and that price includes the 365-Day Done Right Promise. Every job gets a documented photo record under Clause 4, running continuously since 2009. Materials come through our Haven buying network, procured from Famco, Olympia Chimney, and Copperfield suppliers specifically to keep customer prices honest.

DIY or Call Us?

There’s a safe middle ground here, and then there’s a hard stop. You can check whether the handle or chain operates freely, shine a flashlight up the flue to spot obvious rust or a detached plate, and confirm the model stamp if it’s legible. What you should not do is climb into the firebox or attempt to remove a stuck plate yourself.

The damper frame is anchored into masonry with wedge bolts or set in the original construction mortar. Removing it without supporting the flue throat risks dropping debris into the liner or destabilizing the smoke chamber above. More directly: you’re working overhead, in a tight space, with rusted metal that can shear suddenly. We’ve retrieved plates that homeowners partially removed and then couldn’t reinstall, leaving the flue fully open until we arrived.

If you’ve confirmed the symptoms and want the exact part matched to your Famco model, call (469) 240-3101. We’ll quote a written price before we schedule, and we’ll bring both pivot sizes.
