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.

AfterOlympia Chimney Chimney Cap & Crown in Astoria: What to Know First
We repair and replace Olympia Chimney caps and crowns all over Astoria, usually within one visit. Most cap jobs run $275-$700 installed, and crown work lands between $450 and $1,400 depending on what we find once we’re up there. The honest answer is that we’ll tell you if it can wait, and we’ll show you camera footage before we recommend anything.
If you own a home in Astoria with an Olympia Chimney system, this page walks through how their caps and crowns wear in our climate, what repair actually costs around here, and the specific things we check on every Olympia job. Call (929) 822-6306 and you’ll get a live person, not a phone tree.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia makes solid equipment. But around Astoria, with snow building up on flat rooftops and salt drifting off the East River, their caps and crowns fail in ways you only learn from watching roofs for a few decades. Here’s what we actually see.
- Galvanized cap bases rusting from the inside out on flat-roof installs. Astoria’s old rowhouses collect standing water, and if a cap base sits even a half-inch too low, that moisture wicks up into the seams. We pull the old cap, clean the flue tile down to sound material, and set the replacement on a raised stainless base with a proper drip edge so water sheds before it thinks about rusting.
- Olympia masonry crowns cracking along the outside edge from freeze-thaw. The flush-mount crowns on older Olympia systems crack after enough Astoria winters because the crown edge sits flush with the brick, and water pools right where the two meet. We build the new crown with an overhang, a drip groove cut into the underside, and a flexible bond breaker so the crown moves without cracking the flue tile beneath it.
- Spark arrestor mesh clogging faster than it should on Olympic multi-flue caps. We pull enough pigeon nesting and balloon debris out of Astoria flues to know that standard 5/8-inch mesh lets too much through. When an Olympia cap’s mesh has plugged and you have a smoky draft, we’ll recommend a quarter-inch mesh upgrade. It keeps the birds out without choking the draft.
- Hinge and handle failures on Olympia top-sealing dampers. Many Astoria homes with Olympia systems have top-sealing dampers instead of traditional throat dampers. The cast handle arms fatigue, the cable stretches, and the damper either won’t stay open or won’t seal. We replace the arm and cable as a set, lube the pivot, and check the tension so it opens with one hand and closes tight enough to hold back a winter draft.
- Cap-to-flue fit mismatch from mismatched brick repairs over the years. Half the Olympia caps we replace in Astoria were the wrong size to begin with. A roofer patched a chase, a previous owner added a cap from the hardware store, and now the flue has a cap sliding around on top like a loose lid. We measure the actual flue opening, not the old cap, and order the correct Olympia-specific size or a proper custom fit.
Our Olympia Chimney Chimney Cap & Crown Process
Here’s how a typical Olympia cap or crown job goes once you call us in Astoria.
- 1
You call and talk to a person. Wendell or one of the crew takes the call, asks what’s going on, and tells you upfront what a diagnostic visit costs and whether you’ll pay a trip charge. Inside Queens, you don’t.
- 2
We get on the roof and document everything. Before anything is recommended, we run a camera down the flue and take photos of the cap, crown, chase, and flashing. You see everything we see.
- 3
We tell you what needs doing and what doesn’t. If the crown can be sealed rather than rebuilt, we’ll say so and give you the cost difference. If a cap can be cleaned and reattached, we’ll tell you that before we suggest replacement. No guesswork, no scare talk.
- 4
Parts decision. When we do replace a cap, we order the correct Olympia size or an aftermarket stainless equivalent. If the aftermarket is better for your specific flue configuration, we explain why, and it’s your call, not ours.
- 5
The work. Cap installs usually take under an hour. Crown rebuilds take three to six hours depending on how much prep the flue tile needs. We never leave a job with open mortar joints or loose flashing.
- 6
The test and the walkthrough. We fire the system when appropriate, camera-check the final result, and walk you through what was done. If anything isn’t right within 90 days, one call brings us back at no charge. That’s the 90-Day Done Right Promise, and it’s in writing on every ticket.

FAQs
No. Replacing a worn cap or crown with a properly sized part does not void your Olympia warranty, as long as the flue system itself isn’t altered. We keep the flue configuration intact and document every step, so if you ever need a warranty claim on the liner or fireplace, you have before-and-after photos showing nothing else changed.
If the cracks are hairline and the crown still slopes away from the flue, you can usually seal it for a few hundred dollars. If the crown has crumbled along the edges, separated from the flue tile, or pools water, you need a rebuild. We show you the camera footage and give you a straight opinion, even when the cheaper option is the honest one.
Standard Olympia caps and common multi-flue sizes are usually available within three to five business days through our local suppliers. Custom stainless caps take up to two weeks. If your cap is gone and the flue is exposed, we’ll cover it with a temporary aluminum cap same-day so no rain or pigeons get in while the right part comes in.
In most cases, yes. If the cap body is sound and only the mesh or spark arrestor has torn or clogged, we can replace just that section. When the base is rusted or the cap has pulled loose from the flue, replacement is the smarter money. We’ll show you which situation you’re in before any work gets approved.
Water keeps getting into the masonry. In Astoria’s freeze-thaw cycle, those hairline cracks widen, and eventually moisture reaches the flue liner and the smoke chamber. That’s the point where a $400 seal job becomes a $4,000 liner job. Some crowns can wait a season. Some can’t. One call to (929) 822-6306 tells you which one you have.
