Famco damper repair in Trenton typically runs $280-$450 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 repair in a single visit. Most Trenton homeowners discover the problem on the first cold night when smoke won’t draft properly or they feel a cold downdraft even with the damper “closed.”

Which Famco Models This Applies To

Famco manufactures throat dampers in several series, and the repair approach differs by age and construction. The cast-iron plate dampers common in 1970s and 1980s Trenton builds, particularly in the Chambersburg and Mill Hill neighborhoods, carry a 7½-inch or 8-inch plate with a right-hand pivot pin. The stainless pivot-bar assemblies from the 1990s forward use a left-hand thread on the control nut, a detail that trips up owners who try to tighten what they should be loosening.

To identify your model, look for the stamped Famco logo on the damper frame’s front edge, visible from the firebox with a flashlight. If the stamp is worn away, measure the plate width and note the control mechanism: chain pull, rotary knob, or side-mounted lever. We carry both OEM Famco replacement plates and quality aftermarket equivalents from Olympia Chimney that match the original specifications. For older cast-iron frames with hairline cracks, we generally recommend the full assembly replacement, since a new plate in a distorted frame will never seat square and you’ll be chasing smoke for years.

Signs Your Famco Damper Repair Is Failing

• The damper won’t open fully or hangs at an angle. The pivot pin has corroded or the frame has shifted in the throat. In Trenton’s older masonry, freeze-thaw cycles slowly distort the lintel area, and the Famco frame, which relies on a precise rectangular opening, binds against the settled brick. We see this most often in homes north of the Assunpink Creek built before 1960.
• Smoke rolls into the room on light-off. The plate is warped from years of uneven heating, or rust has pitted the sealing edge. A Famco plate that’s even ⅛-inch out of flat will leak enough to kill your draft on a still day.
• Cold air falls down the flue even when “closed.” The plate gasket is gone, or the plate itself has rusted through at the center where condensation pools. Trenton’s humidity swings, especially in spring and fall, accelerate this.
• The control mechanism spins freely or the chain pulls without resistance. The linkage inside the throat has broken or the worm gear has stripped. This is the point where many owners discover they can’t even see the part that’s failed, let alone reach it.
• You hear metal scraping or ticking when operating. The plate has dropped a corner off its pivot, or debris has wedged between plate and frame. Continuing to force it will oval the pin holes and turn a repair into a full replacement.

Replacement Cost & What’s Included

Famco damper repair in Trenton breaks down as follows:

The price spread reflects what we find once we’re looking. A plate swap in a clean throat with good access is straightforward. A frame replacement where the original was mortared into place and the surrounding brick has shifted takes longer and demands more care. We quote the full number before we start, and that number is the number on the invoice. Every Famco damper repair carries our 90-Day Done Right Promise in writing, no arguing. If the chimney’s not right, the fire’s not safe. That’s the whole job.

DIY or Call Us?

There’s a safe middle ground here, and then there’s a hard stop. You can verify the symptoms: shine a flashlight up the flue, check that the plate moves when the control operates, and look for obvious rust or warping from the firebox side. What you cannot safely do is reach into the throat to extract a seized plate or attempt to reset a frame that’s mortared into masonry. The throat sits above the firebox in a space that’s awkward at best, and the metal edges on a corroded Famco plate are razor-thin. More critically, disturbing an old frame without understanding the lintel load above it can shift brickwork you didn’t mean to touch.

We’ve rescued enough DIY attempts in Trenton to say this plainly: if you’ve gotten to the point of needing tools beyond a flashlight, you’ve gotten to the point of needing a trained technician. Call (856) 519-0832 and we’ll give you a straight answer about what you’re looking at, no charge for the conversation.
