Famco Damper Repair: The Denver Owner’s Guide

Famco damper repair in Denver typically runs $280-$520 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock Famco-compatible damper parts on our trucks and can usually match your model same-day. Most Denver homeowners discover the problem on the first cold snap in October or November, when they open the damper and it won’t seal, won’t stay open, or drops rust into the firebox.

Which Famco Models This Applies To

Famco manufactures throat dampers and top-sealing dampers under several product lines, and the repair approach differs by type. The Famco FD series throat dampers, common in Denver homes built between 1985 and 2005, use a 13-by-13-inch or 16-by-16-inch cast-iron plate with a right-hand pivot. The Famco TD series top-sealing dampers, installed on masonry chimneys throughout Capitol Hill and Wash Park, mount to the flue tile with a stainless cable running down to the firebox.

To identify your part, look for the stamped model number on the damper frame edge or the cable housing. If the stamp is rusted away, measure the throat opening width and depth, and note whether the pivot is left or right. We carry both OEM Famco replacement plates and aftermarket equivalents from Gelco and Olympia Chimney through our Haven buying network. For the FD series, we typically recommend the OEM plate; the casting tolerances on aftermarket plates can leave a gap that leaks conditioned air in Denver’s dry winters. For TD series cable assemblies, the aftermarket stainless cables we stock meet the same 1,500-pound test spec as Famco’s and cost 20-30 percent less.

Signs Your Famco Damper Repair Is Failing

• The damper won’t stay fully open. The worm-gear or chain tensioner on Famco throat dampers strips after roughly 15-20 years of heat cycling, especially in Denver’s altitude where combustion temperatures run higher. The plate drifts closed during a fire, forcing smoke into the room.
• You feel cold air dropping even when the damper is “closed.” The cast-iron plate warps or the frame rusts at the seat, creating a gap that pulls heated air up the flue 24 hours a day. In older Denver bungalows near Federal Boulevard, we regularly measure gaps of 3/8 inch or more that the owner never noticed until the gas bill spiked.
• Rust flakes or mortar debris fall into the firebox when you operate the handle. This means the frame is corroding where it embeds in the smoke chamber, or the plate is spalling. Either way, particles are obstructing the seal surface.
• The cable on a top-sealing Famco TD won’t retract or hangs slack. The stainless cable frays at the swivel joint after repeated freeze-thaw cycles on Denver roofs, or the spring housing fills with creosote and jams. A stuck-open top damper is an open flue; a stuck-closed one means no fire until it’s freed.
• You smell smoke or creosote odor from the fireplace when it’s not in use. A failed seal lets downdraft carry odor into the house, common in Denver’s spring wind events along the Front Range. The damper may look closed from below and still leak.

Replacement Cost & What’s Included

These are installed prices in the Denver metro, including the NFPA 211 Level 2 camera inspection we perform before quoting. The range reflects access difficulty: a FD frame replacement in a deep smoke chamber takes longer than a simple plate swap, and a TD unit on a two-story roof in Cherry Creek adds rigging time compared to a single-story in Berkeley. We deliver a written price before work starts, Clause 1 of the Haven Standard, and every damper repair carries our 365-Day Done Right Promise. The photo record of your flue condition, damper seat, and completed installation is archived under Haven Standard Clause 4, same as every job since 2009.

DIY or Call Us?

There’s a short list of things a homeowner can safely check. Verify the handle moves freely. Look up the flue with a flashlight for obvious rust or a detached cable. Check that the plate sits flat when closed. Beyond that, damper repair involves working inside the smoke chamber or on the roof at the flue top, often with compromised footing and always with creosote exposure. The cast-iron plates weigh 15-25 pounds; dropping one into the firebox cracks the refractory panel. We don’t recommend DIY on this part.
