Olympia Chimney Damper Repair: The Hempstead Owner’s Guide
Olympia Chimney damper repair in Hempstead typically runs $340 – $620 installed, and most jobs are done within two hours of arrival. We stock the common Olympia Chimney replacement damper plates, frames, and hardware kits on our trucks so there’s no second visit for parts. The way most homeowners find out their damper has failed is a draft that won’t quit, a damper handle that spins without resistance, or a heating bill that jumps in December with no other explanation.
In Hempstead, where winter winds come off the Atlantic and push hard against older chimneys, a failing damper is a real problem. It’s the part that sits just above the firebox and closes off the flue when there’s no fire. When it won’t seal, your heated air goes straight up the chimney. When it won’t open, you get smoke rolling back into the living room. Both failure modes are common on Olympia Chimney units after about 12 to 18 years of use in Nassau County’s damp, salt-tinged air.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes two main damper lines we see in Hempstead homes: the Olympia Top-Mount Damper series (installed at the flue opening on the chimney crown) and the Olympia Throat Damper series (the traditional cast plate just above the firebox). Both use specific hardware that does not interchange between series. A throat damper plate from an Olympia unit will not fit the frame of a Famco or Copperfield unit, even when the firebox dimensions look close.
The compatibility gotcha we see most is the clamp-style mounting bracket on Olympia throat dampers. Older Olympia units used a 3/8-inch hex-head clamp bolt; newer production switched to a 7/16-inch bolt. If you order a replacement bracket online and match it only by eye, you’ll get the wrong one about half the time. That’s why we always pull the old part, check the bolt size and plate thickness with a caliper, and match it before we quote. Flint Chimney Co Hempstead is an independent service provider, not affiliated with Olympia Chimney, but we install a lot of their hardware and keep the correct components on hand.
Styles & brands we work with





Signs Your Olympia Chimney Damper Repair Is Failing
- The handle spins free or flops loose. This usually means the internal linkage pin between the handle rod and the damper plate has sheared. The fix is a replacement linkage kit, not a full damper assembly.
- Cold air pours into the fireplace when it’s closed. The damper plate has warped or the seating edge has corroded. In Hempstead homes near Fulton, we see this accelerated by years of humid summer air condensing in the flue.
- Smoke rolls back even with a hot fire going. The damper isn’t opening fully. Grease and creosote can bind the pivot points over time. A cleaning sometimes restores travel; a bent plate needs replacement.
- You hear a rattle or clank from the fireplace on windy days. This is usually the damper plate pivoting because the spring tension that holds it in position has failed. Left alone, the plate can crack at the hinge.
- You see rust trails or a visible crack in the damper plate when you shine a light up. Cast plates on Olympia throat dampers aren’t meant to be repaired by welding; the metallurgy doesn’t take a reliable repair. Replacement is the right call.
Replacement Cost & What’s Included
Olympia Chimney damper repair in Hempstead:

- Full throat damper assembly (plate plus frame): $420 – $620 installed

What you can safely check yourself: pull the damper handle and watch whether the plate moves, shine a flashlight up and look for visible rust or cracks, and listen for the rattle on a windy day. That tells you the symptom, and you’re welcome to call us and describe it so we can give you the likely repair cost over the phone.
Where DIY goes wrong: dropping a damper plate down the flue when you unbolt the wrong side, stripping a linkage pin that’s been heat-seized for a decade, or worse, working on a ladder at the chimney crown to reach a top-mount unit. That’s a two-story fall with no second chance. The damper itself isn’t dangerous to handle, but working at the flue opening on a Hempstead roofline absolutely is. Call (516) 559-6922 and we’ll do the whole job from the roof or the firebox with the right hardware and a written warranty.
FAQs
An Olympia throat damper plate in Hempstead weather lasts 12 to 18 years on average. Top-mount dampers last a bit longer, closer to 15 to 20 years, because they sit above the heat and are less exposed to the wet, salty air that accelerates corrosion at the firebox level. A linkage kit commonly fails first, and replacing that early can add years to the plate’s life.
Yes, for linkage and bracket failures, we repair. For a cracked, warped, or rusted-through damper plate, replacement is the only fix that actually works. Call (516) 559-6922 for an honest assessment and the written price either way. We won’t sell you a full assembly when a $120 linkage kit solves it.
Most Olympia damper plate replacements in Hempstead are done within two hours. Full frame swaps take closer to three when we need to grind out the old mounting angle and set the new frame. Top-mount damper replacements usually take about two and a half hours from setup to cleanup.
Yes. We keep common Olympia throat damper plates, linkage kits, and top-mount damper units on the truck, along with compatible hardware from DuraFlex, HeatShield, and Gelco for other chimney repairs. If we quote your repair and find a part we don’t have, we’ll get it ordered and have it installed before the week is out.
