Famco Damper Repair: The Denton Owner’s Guide

Famco damper repair in Denton 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 Denton homeowners discover the failure when smoke rolls back into the living room on the first cold night, or when they spot daylight through a rust-eaten plate they never could open or close fully.

Which Famco Models This Applies To

Famco manufactures throat dampers in two primary configurations: the traditional cast-iron frame-and-plate assemblies found in masonry fireplaces built from the 1960s through the early 2000s, and the lighter stamped-steel retrofit dampers sold through HVAC and chimney supply houses. The critical compatibility gotcha is throat width: Famco’s standard line tops out at 36 inches, but they produced a limited contractor-series run at 42 inches for larger Rumford-style openings that were popular in Denton’s 1980s ranch builds near Southridge and Nottingham Woods. Measure throat width at the narrowest point, not the firebox opening. The model stamp, when present, sits on the handle bracket or the frame edge facing the firebox.

We source Famco OEM parts through Haven’s buying network, but we also carry quality aftermarket equivalents from Gelco and Olympia Chimney when the original series has been discontinued. The aftermarket route saves roughly $40-$90 on parts without sacrificing fit, though we always show you both options in writing before ordering.

Signs Your Famco Damper Repair Is Failing

• Smoke back-drafting on startup. The plate no longer seats flat against the frame, letting exhaust leak past. In Denton’s clay-heavy soil zone, subtle foundation shift over a decade can torque the frame just enough to break the seal.
• Handle spins freely or won’t grip. The worm-gear or pinion mechanism inside the control assembly has stripped. Famco’s cast gears hold up better than stamped alternatives, but they still wear after 15-20 years of seasonal cycling.
• Visible rust holes or scale on the plate. Condensation from gas logs or humid summer air pools on the plate when it’s left closed. Denton’s humidity swings, 40% in winter to 75% in summer, accelerate this more than drier Texas markets.
• Daylight visible when closed. Warping from overheated fires or corrosion thinning has opened a gap. Even a half-inch channel pulls enough room air to spike your heating bill and invite downdrafts.
• Rattling or clanking during wind. The plate has detached from its hinge pin or the frame has loosened in the mortar bed. Left alone, it can drop fully open or closed without warning.

Replacement Cost & What’s Included

These are installed prices in Denton, including the camera inspection we perform before and after to verify full closure and proper draw. The range moves with access difficulty: a standard masonry throat with no smoke chamber narrowing sits at the low end; a sloped firebox or tight lintel clearance adds labor time. Every quote is written, itemized, and signed before work starts, Clause 1 of the Haven Standard. Parts carry a 5-year defect warranty; our labor is covered by the 365-Day Done Right Promise.

DIY or Call Us?

You can safely confirm the model number, measure throat dimensions, and check for obvious rust or detached hardware from the firebox side. Do not attempt to remove or adjust a seized damper plate from the roof. The assembly sits at throat level, often requiring a chimney sweep’s rod tools and headlamp to reach; more importantly, a dropped plate or slipped tool in the flue can damage the liner or block the chimney entirely. The spring-tension handles on some Famco retrofits store enough torque to snap fingers if disassembled without a vise grip. The camera doesn’t guess, and neither do I - call (940) 373-6912 and we’ll show you exactly what failed before you decide on the fix.
