Famco Damper Repair Nationwide

Famco Damper Repair: The Pasadena Owner’s Guide

Famco damper repair in Pasadena typically runs $110 – $280 installed, depending on whether we’re replacing a damper blade, the control cable, or the full frame assembly. We stock Famco-compatible replacement parts on our trucks, and most repairs are done the same visit. The way Pasadena owners usually find out their Famco damper has failed is simple: a chimney that won’t draw when a fire’s lit, a damp, cool draft in summer, or a damper handle that spins without catching. You’ll hear the wind through the flue or smell last night’s ash in the living room. That’s your damper telling you it isn’t sealing anymore.

The good news is most Famco damper failures are repairable and the fix is quick. The real issue is knowing exactly which Famco part you have and whether the failure is in the plate, the linkage, or the frame. That’s what this page covers.

Key Takeaways:

• Famco dampers in Pasadena typically fail at the blade edge seal or the control rod linkage, not the frame.
• We bring Famco-compatible parts on the truck, so most repairs happen in one visit.
• Every repair gets a written price before work starts and a one-year written guarantee.
• If you’re not sure whether you have a Famco damper, the model stamp on the frame tells you in thirty seconds.

We’re an independent service provider in Pasadena. We’re not affiliated with Famco, but we work with their dampers every week and stock replacement parts compatible with all their common residential series.

Which Famco Models This Applies To

Famco makes two damper lines that show up regularly in Pasadena fireplaces: the TD series (top-sealing dampers, mounted at the flue top) and the UD/AD series (throat dampers, mounted just above the firebox, the cast-iron original-style unit). The distinction matters because the repair path is completely different. A TD-series failure usually means the cable snapped at the mounting point or the silicone gasket has flattened. A UD-series failure is typically the cast blade warping, the pivot pins seizing, or the ratchet handle losing teeth.

To identify your model, look for the raised lettering on the damper frame. On a throat damper, you’ll see it on the edge of the frame when you look up from the firebox with a flashlight. On a top-sealing damper, the stamp is on the chimney cap assembly at the flue tile. If the stamp is worn off, you can measure the flue opening: Famco throat dampers for residential use generally run 6″, 8″, and 12″ blade widths. Top-sealing models are built to your specific flue tile size.

One compatibility gotcha we see constantly in Pasadena: aftermarket blades often don’t match the original frame’s pivot and landing geometry. Famco frames are sized to their own blade casting, and a generic “universal” blade from a box store can bind on the landing edge or leave a smoke path at the firebox front. That’s why our trucks carry OEM Famco-compatible parts, not universal substitutes. The parts-cost difference is often just $30 – $60, and the OEM part seals correctly the first time. If your frame is too worn to take a blade replacement reliably, we’ll tell you and show you the slop in the pivot pin before we quote anything.

Hank Delano, who owns Flint Chimney Co Pasadena, has been working on Famco dampers since before the TD series was widely adopted in the San Gabriel Valley. His rule is simple: if the part number doesn’t match what came off, it doesn’t go on.

Signs Your Famco Damper Repair Is Failing

• The handle spins or doesn’t hold position. On UD-series throat dampers, the ratchet teeth in the handle wear down from twenty years of opening and closing. Once the teeth are rounded, the handle won’t stay set and the damper drops shut. That’s a ratchet and control-rod replacement, not a full damper replacement.
• A cold draft comes down the chimney in summer. This points to the blade seal failing. The sealing surface on Famco dampers is a machined edge that meets the frame when closed. Over time, soot builds on the landing, the blade warps slightly, and you get an air gap. A cleaning and blade re-alignment often fixes it.
• Smoke backs up into the room when the damper’s open. Usually this isn’t the damper itself but the flue obstruction above it. We see this in Pasadena homes near mature oak and sycamore canopies, where leaf and twig accumulation blocks the flue and pushes smoke back down. A full inspection tells you whether it’s the damper or the flue. Call it in before burning season, not after.
• You can hear wind whistling through the flue. This is the same seal gap, just audible. On top-sealing TD models, the culprit is usually the rubber gasket at the cap assembly that’s compressed and lost its spring. Replacing the gasket is a simple, low-cost fix on the roof.
• The damper is stuck open or stuck closed and won’t budge. Seized pivot pins from moisture and combustion residue are the cause. In Pasadena’s dry climate, we see fewer rust-seized dampers than coastal LA, but homes close to the Arroyo Seco get more early-morning condensation than you’d expect. If the frame is intact, we free the pin, re-lube the bearing with a high-temp graphite lubricant, and get it moving again.

Replacement Cost & What’s Included

For Pasadena homeowners, here’s what a Famco damper repair costs. A replacement damper blade installed typically runs $110 – $190. A control rod and ratchet handle replacement runs $120 – $210. A full throat damper frame replacement runs $230 – $280. A top-sealing TD-series cap assembly with new gasket and cable runs $180 – $300, depending on flue size. These are installed prices, parts and labor included.

What drives the range is flue size and access. A 6″ throat damper on a single-story Pasadena bungalow is a twenty-minute job. A 12″ blade in a second-floor fireplace with a steep roof line adds ladder time and roof safety requirements. You’ll know your exact price before any work starts because we write it down and hand it to you. That’s how we’ve operated since 2002, and it’s part of what we call the Garrison Standard: written price, written guarantee, no exceptions.

Every repair carries the 365-Day Done Right Promise. If the repair fails inside one full year from the service date, we come back and make it right at no charge. That’s a written guarantee, not a verbal assurance, and it applies to every Famco part we install.

DIY or Call Us?

Here’s the honest version. You can safely handle the inspection part: take a flashlight, look up from the firebox, check if the damper blade is warped, if the handle ratchets cleanly, and if the frame is cracked. Take photos. That information is genuinely useful when you call us. But the repair itself involves reaching into a firebox with old creosote above you, sometimes pulling a spring-loaded control assembly, and on top-sealing models you’re on the roof working with a cable under tension. If the cable snaps at the roof mount while you’re pulling it, you’re buying a new cap assembly anyway.

We don’t recommend DIY repair on Famco dampers beyond the inspection. The parts aren’t expensive, but the failure modes are precise, and getting the blade seating and seal geometry wrong is the difference between a damper that seals and a damper that leaks smoke into the room. The flue either draws or it doesn’t. Let’s find out which. Call us at (626) 657-5513 and we’ll get you on the schedule while the weather’s still mild.
