Olympia Chimney Damper Repair: The Los Angeles Owner’s Guide
If your Olympia Chimney damper won’t open, won’t seal, or has come loose from its frame, we keep the common Olympia-compatible damper parts on the truck and can typically have the repair done the same visit. In Los Angeles, an Olympia damper repair or replacement usually lands between $240 and $560 installed, depending on whether we’re rebuilding the existing assembly or swapping in a new blade and frame. Most owners find out the hard way: the lever suddenly spins with no resistance, or smoke rolls back into the living room on the first cold night in November.
We’ve been doing this long enough to know that a damper failure never announces itself politely. It happens when you’re standing there with a match in one hand and a sense of dread in the other because the last fire of the season worked fine. Here’s what you need to know about fixing it right in Los Angeles, without getting sold a new fireplace you don’t need.
Which Olympia Chimney Models This Applies To
Olympia Chimney builds dampers for a few different setups, and the part number matters. You’re most likely working with either their cast-iron throat damper series (the classic bar-style damper that sits in the firebox, just above the lintel) or one of their top-sealing damper units that mount at the flue opening and seal with a silicone gasket. The throat dampers are model-marked on the edge of the blade or the frame; if the stamping has worn off, the quickest match is measuring the inside frame width. Most Los Angeles fireboxes run 30 to 42 inches wide, but we’ve pulled 1940s damper assemblies in Highland Park that measure 26 inches exactly and have no modern equivalent, so we rebuild those rather than force a wrong-sized blade in.
Olympia’s OEM blades are solid cast iron and hold up well, but the operating linkage is the weak point. We typically use genuine Olympia replacement parts when the blade itself is cracked or warped, and high-quality aftermarket linkage kits from Famco when the problem is a stripped lever or a broken spring clip. There’s no reason to pay OEM markup on a steel rod that does the same job the same way. Ashby Chimney Los Angeles is an independent service provider, so we’re free to choose the part that actually fits your setup and your budget, not whatever the factory tells us to push.
Styles & brands we work with





Signs Your Olympia Chimney Damper Is Failing
- The handle spins without biting. The linkage arm has stripped or the cotter pin let go. The blade isn’t moving even though you’re turning the handle. This is a mechanical failure, not a dirty damper.
- Smoke backs into the room on startup. A cold flue needs a damper that opens fully and a blade that seats correctly. If it only opens halfway or the blade has shifted, the draft can’t establish and the smoke has nowhere to go but your couch.
- The damper won’t fully close in summer. A chunk of mortar or built-up creosote is blocking the blade. The gap lets cooled air escape up the flue all summer, and your AC bill quietly climbs every month in Los Angeles.
- You hear a rattle in the firebox when it’s windy. The damper blade has come loose from the frame, and Santa Ana gusts are moving it around. That’s not just noisy; it’s erosion wear that will only get worse.
- Water streaks or rust inside the firebox. A top-sealing Olympia damper should keep rain out when closed. If the gasket has hardened or cracked, moisture gets in and drips down the flue. In Los Angeles, where we get sudden dumps between long dry spells, that rust cycle accelerates fast.
Replacement Cost & What’s Included
Here’s the straight answer we give on the phone: most Olympia damper repairs in the Los Angeles area run between $240 and $560. A linkage rebuild or new lever assembly is on the lower end and takes about an hour. A full blade and frame replacement, especially on a wider or older firebox, runs higher because of the fitting work. Top-sealing damper replacements with new silicone gaskets center around $480 to $560 for the standard sizes.
Every job gets a written price before we start. That price includes the part, the labor, the cleanup, and a written guarantee on the repair through the Kingswell Guarantee. If the repair fails inside the guarantee period, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s not a line we sell separately: it’s part of every damper repair we do.

You can safely check a few things: is the handle physically connected to the linkage? Is the blade blocked by a loose chunk of mortar? Can you see an obvious broken spring clip? Those are fine to look at from the firebox opening. Where DIY goes wrong is anything involving removing the damper assembly from the frame. Cast iron blades are heavy, and if one drops on a hand or foot, you’re making an ER visit part of your weekend. If the rod operates but the blade doesn’t move, or if the corners look warped, call us at (213) 652-7061 and we’ll diagnose it properly. We don’t charge for an estimate, and we won’t sell you a liner or a masonry rebuild unless a camera inspection proves it’s needed.
FAQs
Thirty to fifty years is a fair range in Los Angeles weather, but that assumes the flue cap is doing its job and the firebox stays dry. Chimney dampers fail early when water gets in, and the gasket on top-sealing models typically needs replacement every seven to ten years – just like a door gasket on a stove, it hardens from heat cycling and stops sealing. If yours is pushing fifteen and you’ve never touched it, call (213) 652-7061 and we can check the gasket during a routine sweep.
We repair more dampers than we replace. Stripped linkage, broken spring clips, loose handles, and seized pivot points are all repairable on-site, and we keep the common repair parts on the truck. Replacement only makes sense when the blade has warped or cracked to the point that it won’t seat square against the frame. If we can rebuild it for $240, we’ll tell you that instead of pushing a $500 replacement.
Most linkage and gasket repairs are done in about an hour from setup to cleanup. A full blade replacement might run 90 minutes on a standard firebox, and wider or out-of-square openings add fitting time. We book a real arrival window, not a four-hour maybe, and we leave the firebox and hearth cleaner than we found it. Call (213) 652-7061 and we’ll give you a written price and a time window that holds.
We keep the common Olympia blade sizes, linkage rods, spring clips, and top-sealing gaskets on the van because they cover about 85 percent of the dampers we see across Los Angeles, from Atwater Village to Silver Lake to the Valley. We also stock compatible parts from DuraFlex, HeatShield, Gelco, and Famco when the OEM part isn’t the right call. If we don’t have your exact part on the truck, we can usually have it within two business days and will tell you that plainly before you’re stuck waiting.
