Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
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 Chimney Cap Installation: The Annapolis Owner’s Guide
We stock and install Olympia Chimney-compatible chimney caps throughout Annapolis, with most cap replacements running $285 to $640 installed depending on flue size and roof access. The work is usually done in one visit, and we carry the common Olympia sizes on the truck. Most Annapolis homeowners discover the cap has failed the same way: a rust stain on the chimney crown after a storm, or a missing cap lying in the yard after February winds off the Severn.

A chimney cap is not decorative. It keeps rain out of the flue, blocks birds and squirrels from nesting, and stops embers from landing on cedar-shake roofs that are everywhere in the older Annapolis neighborhoods. When an Olympia cap rusts through or blows off, the flue is open to everything Maryland weather can throw at it.
Which Olympia Chimney Models This Applies To
Olympia Chimney builds stainless steel caps across three main lines we see in Annapolis homes: the standard round caps for single-flue masonry chimneys, the multi-flue caps that span larger rectangular crowns, and the bolt-on mesh caps for prefab chimneys. The single-flue round caps are the most common on the brick chimneys in Murray Hill and Admiral Heights. The multi-flue versions show up on older colonials and split-levels in Hillsmere and Cape St. Claire where two or three flues share one chimney.
The compatibility gotcha is the flue tile measurement. An Olympia cap sized for a 13″ x 13″ flue will not seat properly on a 13″ x 9″ flue, and the difference is enough that the cap rocks in the slip section and loosens within a season. When we arrive, we measure the outside dimension of the flue tile with a tape, not the inside. That outside dimension, plus the number of flues and whether the crown is poured concrete or precast, determines the exact Olympia model that fits. We stock the standard sizes and order odd ones with a two-to-three-day turnaround.
We are an independent service provider, not affiliated with Olympia Chimney. When an OEM Olympia cap is the right call, that’s what we install. When a homeowner’s old cap is an odd size or they want a heavier-gauge option, we also carry equivalent caps from DuraFlex and Gelco and will tell you the price difference in writing before anything is ordered.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing

- Water in the firebox after rain. If you see a puddle or damp ash after a hard Annapolis rain, the cap’s hood is missing or rusted through and the flue is taking water directly. That water migrates down into the smoke chamber and can soak the firebrick in one good storm.
- Rust staining down the chimney crown. When the galvanized mesh or the stainless hood starts breaking down, iron oxide runs down the brick. In Annapolis’s salt air, that breakdown happens faster near the water in Eastport and along the Severn than it does inland.
- Animal noise in the chimney. Birds, squirrels, and raccoons don’t need much. A cap with a torn mesh panel or a missing corner brace is an invitation. We have pulled live animals out of chimneys in Annapolis that had caps, but the mesh had failed where it was riveted to the frame.
- Water leaking through the ceiling near the fireplace. This is the late-stage symptom, and by the time you see it, the water has already been running down the inside of the flue for months. The cap failing is often the first link in that chain.
- Visible rust-through or missing sections. You should be able to see this from a ladder. If the mesh is gone in patches or the hood has pinholes, it is past the point of repair and needs replacing.

AfterReplacement Cost & What’s Included
In Annapolis, replacing a single-flue Olympia chimney cap typically runs $285 to $440 installed. Multi-flue caps start around $420 and go up to about $640 depending on flue count and crown size. The cap itself is $90 to $230 of that total depending on the model. The rest is the site visit, roof access, removal of the old cap, measuring and setting the new one, and sealing the mounting hardware.
What drives the higher end of the range is roof pitch and access. A cap on a one-story rancher in Annapolis Roads costs less to swap than a cap on a three-story colonial on a steep lot where we need a roof ladder and a spotter. If the old cap’s mounting legs are rust-welded to the crown, removal takes longer. We write the price before work starts, per Haven Standard Clause 1, and that number is what you pay. Every cap installation includes a photo record of the old cap, the measured flue, and the finished install, per Clause 4. Work is covered by our 365-Day Done Right Promise.

DIY or Call Us?

You can safely check your cap from the ground with binoculars: rust color, tears in the mesh, missing sections, or a cap leaning off-center. If you have a safe way to get eyes on the crown from a ladder that never goes past your gut, you can look at the mounting legs and the seal around the slip section. What we do not recommend is doing the replacement yourself if it means walking a roof, especially a damp Annapolis morning roof with a pitch steep enough that the ladder has to be tied off.
The failure we see most from DIY cap work is the cap not being sized right or the legs not being sealed, which means the new cap is loose by the first big storm. The second failure is dropping the old cap down the flue while pulling it, which turns a $300 job into a liner inspection and a fishing expedition. If you want to talk through what you’re seeing, call (443) 274-4231 and we’ll walk through it with you before anyone gets on a ladder.
FAQs
A stainless Olympia cap in Annapolis typically lasts 8 to 12 years before it needs replacing, but homes within a mile of the water in Eastport or along the Severn can see rust-through in as little as 5 to 7 years because of salt air. Galvanized caps and the galvanized mesh used in some older Olympia models go sooner. Call (443) 274-4231 and we’ll give you a straight answer on whether what you’re seeing is age or sea air.
If the only issue is a torn mesh panel or a loose mounting leg, we can usually repair it for $120 to $180 and you’ll get more years out of it. If the hood itself is rusted through or the frame is bent, repair does not make sense and we’ll tell you that plainly before you spend a dollar. Call (443) 274-4231 and we’ll tell you which camp your cap falls into.
Most single-flue cap replacements take 45 minutes to an hour on site. A multi-flue cap or a steep roof adds time, but the job is still done in one visit. We send a text when the truck is on the way and you get a photo record of the finished work before we leave the driveway.
We stock the standard single-flue Olympia sizes on every truck, so most Annapolis cap replacements happen the same visit. Odd sizes and multi-flue caps are ordered and installed within a few days. If you know your flue tile’s outside dimension when you call, we can tell you before we arrive whether we have the right cap loaded.
If your Olympia chimney cap has failed or you want a straightforward answer on whether it’s still doing its job, call (443) 274-4231 for a free estimate. We will measure, show you what we found, and put the price in writing before any work starts.
