Famco Damper Repair: The Littleton Owner’s Guide

Famco damper repair in Littleton 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 Littleton homeowners discover the problem the first cold night of fall, 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 has manufactured dampers under several series names over the years, and the part you need depends on the throat size and whether your fireplace is factory-built or site-constructed masonry. The most common units we see in Littleton homes are the Famco 8-inch and 13-inch throat dampers, often found in homes built between 1975 and 1995 in neighborhoods like Columbine Knolls and the older sections of Ken Caryl Ranch.

To identify your model, look for a stamped steel tag on the damper frame, usually visible from the firebox with a flashlight. If the tag is gone, measure the throat opening width and depth. The critical gotcha: Famco’s 13-inch damper uses a left-hand pivot pin that isn’t interchangeable with the 12-inch version, even though the frames look identical. We’ve seen homeowners order the wrong part twice before calling us.

We source Famco parts through Haven’s buying network, which also stocks DuraFlex, HeatShield, and Gelco components. For discontinued Famco models, we match with quality aftermarket equivalents that meet the same ASTM A36 steel spec. We’re an independent service provider - not affiliated with Famco - and we’ll tell you straight when an aftermarket part saves money without sacrificing function.

Signs Your Famco Damper Repair Is Failing

• The handle turns but the plate doesn’t move. The linkage between the handle spindle and the damper plate has corroded or the cotter pin has sheared. In Littleton’s dry climate, the pin usually fails before the plate itself rusts through.
• Cold air pours down the chimney even when the damper is “closed.” The plate is warped or the frame has settled out of square, leaving a gap that lets conditioned air escape. We measure the leak with a smoke pencil during our Level 2 inspection.
• The damper won’t stay open on its own. The spring tension has weakened or the notched bracket has worn smooth. This is more common in Famco units that see heavy use through long Front Range burning seasons.
• You hear metal scraping when operating the handle. The plate has dropped off one pivot pin and is dragging against the frame. Continuing to force it will oval out the pin hole and turn a $280 repair into a $520 full assembly replacement.
• Rust flakes or water stains appear in the firebox below the damper. The plate’s galvanized coating has failed, usually at the weld seam. Once rust starts, the plate thins fast - we’ve measured 16-gauge Famco plates down to paper-thin in spots after 20 years of condensation cycling.

Replacement Cost & What’s Included

The price spread depends on three things: whether we can access the damper from the firebox or need to work from the roof, the condition of the surrounding smoke chamber mortar, and whether your Famco model is still in production. We deliver a written price before any work starts - Haven Standard Clause 1 - and that price includes the 365-Day Done Right Promise. Every job gets a documented photo record under Clause 4, running continuously since 2009.

DIY or Call Us?

There’s exactly one thing a homeowner can safely check: whether the handle set screw has simply loosened. Tighten it with a flathead screwdriver while the damper is cool. Beyond that, the risks stack up fast.

The damper sits at the top of a hot, cramped smoke chamber. The pivot pins are under spring tension and can launch into your face if released wrong. More critically, a misaligned damper plate that doesn’t seat fully creates a slow draft leak - you won’t notice it, but it’ll pull heated air up the flue all winter and can allow carbon monoxide backflow if the chimney ever pressurizes. The camera doesn’t have an opinion - it just shows you what’s there. We bring the camera, the right Famco part, and the torque wrench to set the pivot pins to spec. Call (720) 439-4666 and we’ll book a time that works.
