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 Annapolis Owner’s Guide
Olympia Chimney damper repair in Annapolis typically runs $340-$580 installed, and we stock the most common repair components on the truck so the work is usually done in a single visit. Most homeowners discover the problem the first cold night of the season: they reach for the damper lever and it swings free, or they smell fireplace air backing into the room and realize the damper hasn’t sealed in years. The part fails gradually in tidewater air, then all at once when the cast-iron frame warps or the pivot pin lets go.

We’re an independent chimney service company in Annapolis, not an Olympia Chimney affiliate, and we repair these dampers regardless of where the original was purchased. Here’s what actually goes wrong, what it costs to make right, and how to tell which situation you’re in.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures top-sealing dampers (the cast-aluminum cap that sits on the flue tile at the chimney crown) and throat dampers (the traditional cast-iron plate just above the firebox). Both appear across their Ventinox and Olympia branded product lines, but the failure patterns are completely different.
The top-sealing damper fails at the silicone gasket edge first. Salt air off the Severn and the constant thermal cycling on Annapolis rooftops degrades that seal faster than the manufacturer’s inland projections. A 10-year-old top damper in Eastport or Murray Hill with a cracked gasket lets a steady draft pull heated air out of the house year-round. On throat dampers, the weak point is the pivot pin and the cast frame ears that hold it. We see the same failure in Cape St. Claire and Arnold homes built in the 1980s and 1990s: the lever still moves but the plate no longer seats, because one of the cast ears has cracked.
Identifying what you have is straightforward. Climb up and look at the chimney crown. If there’s a cast-aluminum cap with a cable running down the flue, it’s a top damper. If you only see a metal plate inside above the firebox, it’s a throat damper. Take a photo of the existing unit and the make tag if there is one. For top dampers without a tag, measure the inside dimension of the flue tile. The most common Annapolis sizing we stock is 13×13, but homes with original clay tile often run 9×13 or irregular custom sizes that require a different mounting kit.
We recommend OEM Olympia Chimney replacement parts when the frame and cable assembly are intact and we’re matching a gasket or spring kit. When the whole unit is shot, quality aftermarket equivalents from Copperfield often cost 20-30% less with the same cast-aluminum construction and a matching manufacturer warranty. We’ll show you both prices in writing before you decide.
Signs Your Olympia Chimney Damper Repair Is Failing

- You can feel a constant draft from the fireplace even with the damper closed. The seal is gone. On a top damper, the gasket has stiffened or cracked. On a throat damper, the plate has warped or the frame has shifted. Either way, conditioned air is leaving your house.
- The damper lever or cable moves but nothing happens. On a top damper, this means the cable has detached from the pulley assembly. On a throat damper, a cast ear has snapped. Both are repairable, but the diagnoser matters: we see what’s broken with a camera before recommending anything.
- Rainwater or rust stains around the firebox. A top damper that won’t fully close lets rain straight down the flue. In Annapolis, this shows up as rust on the damper plate itself and water staining in the firebox.
- You hear a rattle or clank at the chimney top when the wind picks up. That’s the damper plate banging against the frame. It means the spring or cable tension has failed and you’re one good nor’easter from losing the plate altogether.
- Animals in the flue. The damper is the first line of defense. A stuck-open top damper is an invitation to chimney swifts, starlings, and squirrels. We’ve pulled nests out of Olympia Chimney dampers more than once in Shady Side and Riva.

AfterReplacement Cost & What’s Included
Here’s what Olympia Chimney damper repair costs in Annapolis, written out before any work begins:

- Top damper gasket or cable repair: $340-$420 installed. Includes gasket, cable adjustment, and re-seating the plate.
- Full top damper replacement (13×13 standard): $480-$580 installed. Includes the new cast-aluminum damper, mounting, and cable run.

- Custom flue sizing or significant mortar repair: add $80-$150. We’ll quote it on the spot, in writing, based on what the camera shows.
Every quote includes the part, labor, the camera inspection, and a written warranty on our work. You get the photo record before we leave. That’s Haven Standard Clause 4 and it’s been our default since 2009, not an add-on. If a competitor has given you a written quote for the same Olympia Chimney repair, bring it. We’ll give you a free second opinion.
DIY or Call Us?

You can safely do two things before calling us: identify the damper type using the photo method above, and feel for an obvious draft with the damper closed. That’s useful information and it costs nothing. What you shouldn’t do is climb onto an Annapolis roof in the wet months to disassemble a top damper. The cable tension on these units is significant, the cast plates are heavier than they look, and a fall from a chimney crown is a life-changing event. The same caution applies to throat dampers: the cast-iron frame is brittle, and a misaligned plate doesn’t just fail to seal, it can block flue gases from exiting, which is how carbon monoxide ends up where it shouldn’t. This is one of those repairs where the professional’s camera and experience genuinely change the outcome. If you want to know what’s actually broken before you spend a dollar, call (443) 274-4231 and we’ll schedule the inspection. You’ll get the photos whether the repair is simple or not, because you paid for the look.
FAQs
Ten to fifteen years is realistic for a top-sealing damper in this climate, and closer to twenty for a throat damper that’s been maintained. Salt air, rain cycles, and the temperature swings on exposed chimney crowns accelerate gasket aging. Corrine Halstead has seen top dampers fail in as little as seven years on waterfront homes where the original installation wasn’t properly sealed.
Yes, and we’ll tell you honestly when it can’t. Gasket swaps, cable adjustments, and pivot pin replacements fix the majority of what we see. When the cast frame itself is cracked or the plate is warped beyond seating, replacement costs less than the repair would. We show you the camera footage before you choose.
Most damper repairs take 60 to 90 minutes on site. Full top damper replacement can run two hours. We come with the parts loaded, so we’re not making a second trip to a supply house.
We stock the common gaskets, cables, springs, pivot pins, and standard 13×13 replacement dampers. For custom flue sizes, we quote the part and have it in hand before scheduling the install. We also work with DuraFlex, HeatShield, Gelco, Famco, and Copperfield when the job requires a different manufacturer’s component.
If your Olympia Chimney damper isn’t sealing and you want to know exactly what’s wrong before spending anything, call (443) 274-4231. We’ll put a price on the page of the report, send you the photos, and get it done the way the Haven Standard says it should be done. The camera doesn’t guess. Neither do I.
