Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Olympia Chimney Damper Repair: The White Plains Owner’s Guide
If your Olympia Chimney damper is stuck, warped, or letting cold air pour down the flue, we stock Olympia Chimney-compatible damper parts on our trucks and can typically install them the same visit. Most Olympia damper repairs in White Plains run between $285 and $620 installed, depending on whether we’re replacing the damper plate, the frame assembly, or the full top-sealing unit. Owners usually discover the failure when the fireplace won’t draw correctly, or when the living room smells like a campfire the morning after a fire.
The Olympia Chimney top-sealing dampers we see in White Plains homes fail in ways that are predictable. The cable stretches. The pivot hardware corrodes from rain exposure. The gasket material loses its seal after six or seven Westchester winters. We know which parts from the Olympia Chimney lineup match which fireplace throat profiles, and we’ll confirm the part before we ever quote you a price.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes two damper families we regularly service here: the CI Series (sometimes labeled the “Chimney Inn” line) and the L-Series top-sealing dampers. The CI Series is a cable-operated top mount with a cast aluminum frame and silicone gasket, sized by the flue tile opening: 9″ x 13″, 13″ x 13″, and 13″ x 18″ being the three we see most in White Plains. The L-Series is the economy top-sealer, with a lighter aluminum plate and a simpler cable mechanism.
Identifying what you have takes about two minutes. If there’s a bracket mounted inside the firebox, look for a small stamp on the frame, usually “OLY” followed by the flue dimensions. If the stamp is gone, we measure the flue opening width and depth at the throat, then match to Olympia’s sizing chart. Here’s the gotcha we run into all the time with White Plains homeowners: an aftermarket damper plate will sometimes physically fit the opening but the cable anchor point is positioned differently than an Olympia Chimney OEM plate, which means the replacement cable won’t pull at the right angle. We use OEM Olympia Chimney parts when they’re available and still in production. For discontinued sizes, we fabricate a plate using the original frame dimensions and a matching cable anchor position, not just a plate that happens to fit the hole. The damper’s from Olympia Chimney, but the fabricator is local.
Signs Your Olympia Chimney Damper Repair Is Failing

- The damper handle moves freely but the plate doesn’t budge. That’s a cable that has snapped at the pivot bracket inside the flue, the most common failure we see on CI Series dampers after five or six years.
- Daylight is visible around the damper plate when closed. The silicone gasket has compressed permanently or worn away, letting air bypass the seal. This is a gasket replacement, not a full damper swap, and it’s the cheapest repair at around $180 to $260.
- The damper plate sits tilted even after adjusting the cable tension. One side of the pivot hinge has seized with soot and moisture, so the plate won’t seat level. We sometimes can free it without parts; other times the hinge needs replacement.
- Water streaks on the firebox floor after rain. On top-sealing dampers, the gasket around the flue rim has failed, letting water run down the flue wall. That means the seal face is bad and, left alone, the water will eat at the smoke shelf and fireplace floor.
- A rusted-through damper plate with holes in the aluminum. Once the plate corrodes through, the cable can’t tension properly anymore, and you’re not just losing heat; you’re getting precipitation inside the flue where it accelerates creosote breakdown.

AfterReplacement Cost & What’s Included
In White Plains, Olympia Chimney damper repair is priced by what we actually find. Gasket replacement on a CI Series runs $180 to $260. A full OEM damper plate with new cable and hardware runs $285 to $420, with the labor included in that number. If the frame itself is warped or the pivot arms sheared, you’re looking at a complete damper kit replacement: parts plus installation run $520 to $620.
The part cost depends on which Olympia Chimney size your flue needs and whether the OEM component is currently in distribution or if our fabricator handles it. We’ll write down the part number, the quoted price, the scope of work, and the warranty before anyone touches anything. Every one of these jobs leaves with the photo record of the damper condition before and after, per Clause 4 of the Haven Standard. If it’s not done right, we make it right under our 365-Day Done Right Promise.
DIY or Call Us?

What’s safe for you to check: the handle movement, whether the plate is visibly tilted from the firebox floor, and whether daylight shows around the closed damper. If the damper is the cable-operated CI or L-Series, you don’t need to climb anything. The failure is at the flue top, which means someone has to get on the roof and work a cast aluminum frame around an open flue opening. That’s not a handyman-with-a-screwdriver job. The risk isn’t the damper itself; it’s the work location, the elevated ladder work around the flue, and the decision about whether the flue tile the damper seals against is still sound underneath the soot.
We’d rather you call us for the inspection, because the camera doesn’t guess, and neither do we. When our tech shows up, we’ll run the Level 2 camera inspection first, document the damper and the flue liner condition, and give you the part number and written price before any repair is scheduled. Call (914) 350-5204 and we’ll get a named tech and truck date to your home in White Plains.
FAQs
With the truck already carrying the damper part, the repair takes about an hour in most White Plains homes, including the time to run the camera inspection and confirm the flue condition. If the flue tile itself is deteriorating, we’ll tell you that first, because the damper can’t seal against a crumbling flue opening.
Many Olympia Chimney dampers can be repaired, especially the cable pivot failures and the gasket issues; we replace the components that are actually broken rather than swapping the whole assembly. Full frame replacement is reserved for warped or severely corroded frames. The quote we give you will show which approach matches what we saw on the camera. Call (914) 350-5204 for a free estimate.
In Westchester County the freeze-thaw cycle works the gasket and hardware harder than in milder climates, so we typically see CI Series dampers lasting 6 to 10 years before the gasket or cable needs attention. L-Series models run shorter, around 5 to 7 years, because the lighter plate is more exposed to wind and rain. A chimney cap that’s in good condition extends the damper’s life by cutting the direct water load.
We keep the most common White Plains repair parts on the truck: 9×13, 13×13, and 13×18 cable kits, gaskets, pivot hardware, and several full OEM plates. If you have a size we don’t stock, our fabricator in Westchester can supply a plate that matches the original frame geometry, usually within a few days. You’ll know exactly what we plan before we ever start the job.
Talk to Us

If you’ve got an Olympia Chimney damper that’s stuck, leaking air, or letting water in, call (914) 350-5204. We’ll answer with a live person, get your chimney inspected with the Level 2 camera, and hand you a written price before any work starts. Corrine Halstead has spent the better part of two decades doing chimney inspections and cleanings across Westchester County, from older colonials near the Gedney neighborhood in White Plains out to the surrounding communities. We also stock parts and materials from DuraFlex, HeatShield, and Gelco when a chimney damper repair turns up a liner or firebox issue that needs attention. The camera doesn’t guess. Neither do we.
