Famco Damper Repair: The Easton Owner’s Guide

Famco damper repair in Easton typically runs $240-$420 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock Famco-compatible parts on our trucks and complete most replacements in a single visit. Easton homeowners usually discover the problem on the first cold night in November, when the damper won’t open, won’t stay closed, or drops soot into the firebox.

The damper sits right above the firebox, exposed to acid-laden flue gases and the freeze-thaw cycles that hit hard here along the Lehigh Valley. After fifteen or twenty years, the metal fatigues. Famco built solid hardware, but no steel plate lasts forever in a chimney.

Which Famco Models This Applies To

Famco manufactured throat dampers in several configurations, and the part you need depends on the original installation era. The cast-iron frame dampers common in 1970s and 1980s Easton colonials, especially in the historic districts near the Delaware Canal, used a 30-inch or 36-inch plate with a right-hand control hook. Later galvanized steel assemblies, often found in the ranch homes built during the 1990s off Sullivan Trail, switched to a center-pivot design with a different linkage geometry.

To identify your model, look for a stamped part number on the damper frame, visible from the firebox with a flashlight. If the tag is gone, we measure the throat opening and the plate thickness. OEM Famco parts are no longer manufactured, but we source quality aftermarket equivalents from Copperfield and Olympia Chimney that match the original specs. The critical compatibility gotcha: the control arm length and pivot point must align precisely, or the damper will bind and fail again within a season. We carry both 30-inch and 36-inch assemblies on the truck, along with the shorter 24-inch size occasionally found in pre-war Easton twins near College Hill.

Signs Your Famco Damper Repair Is Failing

• The handle moves but the plate doesn’t budge. The linkage has corroded or the pivot pin has seized, usually from creosote buildup hardening in the joint. This is the most common failure we see in Easton chimneys that haven’t been swept in three or more years.
• The plate falls open on its own. The tension spring has weakened or the notched positioning bracket has worn smooth. A damper that won’t stay closed pulls heated air up the flue all winter and can let downdrafts blow cold air into the room.
• You see rust flakes or metal debris in the firebox. The galvanized coating has failed and the steel is exfoliating. In Easton’s climate, with humid summers and freeze-thaw winters, this accelerates once it starts.
• The plate is visibly warped or cracked. Over-firing the fireplace or a chimney fire has overheated the metal. A warped plate never seals properly, and smoke can leak into the room during a marginal draft condition.
• The frame itself is separating from the masonry. The mortar bed has deteriorated, or the original installation used a thin bed that couldn’t handle thermal cycling. This requires refractory repair in addition to the damper replacement.

Replacement Cost & What’s Included

For Easton homeowners, Famco damper replacement breaks down as follows:

• Damper plate only (if frame is sound): $240-$310
• Full damper assembly with frame: $340-$420
• Refractory mortar repair to seat a new frame: add $80-$150

The range reflects accessibility. Some Easton fireplaces, particularly the deeper Rumford-style throats in Center Square Victorians, require extra time to reach and seal properly. Every replacement includes a Level-2 camera inspection so you see the flue condition above the damper, and we photograph the new installation for your records. The 90-Day Done Right Promise covers the work in writing, no arguing. If the damper doesn’t operate smoothly, we come back.

DIY or Call Us?

You can safely check whether the handle moves freely and whether debris is visible on the plate from below. Do not attempt to remove or adjust the damper assembly yourself. The plate and frame are heavy cast iron or steel, positioned overhead in a confined space, and a dropped plate can crack the firebox liner or injure hands and wrists. More critically, an improperly seated damper leaks carbon monoxide and combustion gases into living space.

We’ve replaced enough Famco dampers in Easton to know the binding points and the mortar mixes that hold. Most jobs take two to three hours. Call (610) 756-1504 and we’ll give you a straight price before we book it.
