Olympia Chimney damper repair in Sherman Oaks typically runs $340-$580 installed, and we stock the common pivot plates, springs, and throat assemblies for same-day replacement on most models. Corrine Halstead and our crew carry Olympia Chimney-compatible parts on every truck, so you’re not waiting on a warehouse shipment while smoke backs into your living room. Most Sherman Oaks homeowners figure out their damper’s failed the first cold night they light a fire and the room fills with smoke, or they spot rust flakes in the firebox come October.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures throat dampers in three standard throat sizes: 8×8, 8×13, and 13×13, with pivot-pin spacing that changed slightly after 2018. If your damper plate is stamped “OC” or “Olympia” on the handle side, you’re in the right place. The model number is usually on a metal tag riveted to the frame, visible with a flashlight looking up from the firebox. Pre-2018 units used a 5/16-inch pivot pin; current production runs 3/8-inch, and the bushings are not interchangeable without reaming the frame ears, which we don’t recommend.

We source OEM Olympia Chimney parts through Haven’s buying network, but we also stock Gelco and Famco equivalents where the spec matches. The aftermarket pivot assemblies are galvanized rather than stainless, so in Sherman Oaks’ occasional marine-influenced humidity, we lean toward OEM stainless for anything within five miles of Ventura Boulevard’s elevation dip. We’ll show you both options on the written quote, with the part number, so you know exactly what you’re paying for. That’s Clause 1 of the Haven Standard: have it in writing before work starts.

Signs Your Olympia Chimney Damper Repair Is Failing

• The handle spins freely or drops. The pivot pin has sheared or the bushing has wallowed out. On Olympia Chimney units, the cast-iron bushing seizes before the pin breaks, so by the time you feel slop, the frame ear is often egg-shaped.
• Smoke rolls into the room on startup. The damper plate isn’t seating fully, usually because creosote has built up on the seat ledge or the plate itself has warped from over-firing. In Sherman Oaks, we see this most in the older wood-framed homes along Ventura Boulevard where fireplaces get heavy winter use.
• You feel cold air dropping down the flue when the fireplace is off. The plate gasket is compressed or missing, or the plate has corroded through at the edge. A flashlight inspection from below will show daylight around the perimeter.
• Rust stains on the firebox floor. The damper frame is galvanized steel, but the weld seam at the rear corner is the first place moisture collects. Once rust flakes appear, the frame is typically thinning from the inside out.
• The plate jams half-open or half-closed. Debris in the throat, a bent operating handle, or, more commonly, a cracked pivot plate that binds as it rotates. Olympia Chimney’s pivot plate is a stamped steel piece that fatigues after roughly 15-20 years of seasonal cycling.

Replacement Cost & What’s Included

What drives the range: throat size, whether the frame ears are still square, and whether we need to remove firebrick to access the frame. We don’t quote until we’ve looked. Every Sherman Oaks damper job includes NFPA 211 Level 2 camera inspection up the flue, a written scope with part numbers, and the documented photo record under Haven Standard Clause 4. The 365-Day Done Right Promise covers the installation and the part. If you have a competitor’s written estimate, we’ll beat it or explain why the scope differs, free.

DIY or Call Us?

You can safely check whether the handle operates and whether the plate seats by looking up from the firebox with a flashlight. Don’t stick your head up the throat. What you cannot safely do is remove the damper plate or frame yourself. The assembly sits at the smoke chamber throat, often above head height, and the frame is wedged between masonry courses that can shift if you lever against them wrong. We’ve seen cracked lintels from homeowners who thought they’d just “pop the old one out.” The camera doesn’t lie, and neither does the written quote. If the frame is rusted or the ears are wallowed, this is a trained-technician job. Call (424) 414-6048 and we’ll get you a written price before anyone picks up a tool.
