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 & Crown in New York: What to Know First
Olympia Chimney caps and crowns in New York typically cost between $425 and $1,800 installed, depending on whether you need a standard stainless cap, a multi-flue cap, or a poured crown rebuild. Most jobs are completed the same day we see the chimney, with a written price before any work starts. If you own an Olympia Chimney product anywhere in New York and the cap is rusted, dented, or missing, or the crown is spalling, call (551) 213-5548 for a straight answer and a free estimate.

We’re an independent Olympia Chimney service provider. We are not affiliated with or authorized by Olympia Chimney, and we don’t pretend to be. What we are is a New York chimney company that has worked on enough Olympia caps and crowns to know exactly what fails, why it fails, and what’s worth fixing versus replacing.
Key Takeaways
- Olympia Chimney caps in New York fail most often from galvanic corrosion at the collar, not from impact damage.
- OEM Olympia caps fit correctly, but many quality aftermarket caps outperform the original in coastal-adjacent New York conditions.
- Crown repair or replacement should happen before water gets into the flue and the brick structure below.
- Every job includes a written price, written scope, and camera documentation before and after.
How Olympia Chimney Products Fail - and How We Fix Them

Olympia Chimney builds a solid product, but New York weather has a way of finding the weak points. Here’s what we see on roofs across the city and what we do about it.
- Galvanic corrosion at the cap collar on standard Olympia stainless caps. The stainless mesh and body hold up, but the collar where the cap meets the flue tile often sits in water after heavy rain or snow melt. When the metal reacts with minerals in the mortar, the collar rusts and loosens. We cut the old cap off cleanly, wire-brush the flue tile, and set the new cap with a high-heat silicone bead and mechanical fasteners, never just friction pressure.
- Warped screening on Olympia’s Vacu-Stack and WindBond series caps after nor’easters. Those caps are designed for wind, but the mesh on older units gets brittle after years of thermal cycling. Once the mesh warps, birds can push through and nest in the flue. We replace the mesh or the entire cap and check the flue with a camera before we call the job done.
- Concrete crowns installed over Olympia liners that never got a proper drip edge. This is a New York classic. The original crown was poured flat or with a thin edge, and water runs straight down the brick face. The mortar erodes, the brick spalls, and the liner eventually takes water. We rebuild the crown with a 2-inch overhang and a cut drip edge so water sheds away from the chimney structure.
- Olympia’s multipurpose caps with undersized screens clogging in city air. Around busier New York corridors, the fine stainless mesh on some Olympia caps loads up with soot, pollen, and airborne grit faster than manufacturers anticipate. A partially clogged screen restricts draft and pushes smoke back into the house. We document the restriction on camera, then recommend either a larger-mesh replacement or more frequent sweep intervals depending on the neighborhood.
- Crown cracks from freeze-thaw cycles on Olympia’s cast-in-place crown forms. Hairline cracks in a crown may not look urgent, but in a New York winter, water gets in those cracks, freezes, and pries them wider every season. We seal hairline cracks with an elastomeric crown coat when the structure is sound, or tear out and repour when it isn’t. The camera tells us which one applies.

Here’s how a typical Olympia cap or crown job runs from first call to final photo.
- 1
You call (551) 213-5548. A live person answers, day or night. We listen, ask about the chimney’s age and condition, and schedule a time that works.
- 2
We inspect with a camera. Every visit includes an NFPA 211 Level 2 camera scan of the flue. We look at the cap, the crown, the liner, and the smoke chamber. You see the footage with us.
- 3
We name the part and state the condition. If it’s a warped Olympia WindBond mesh, we say so. If it’s a spalling crown, we show you the photo. Then we tell you the fix in plain terms.
- 4
We price it in writing before any work starts. No exceptions. The written scope includes the exact part or material, the labor, and the warranty. Clause 1 of the Haven Standard requires it.
- 5
We do the work with the right part. We use OEM Olympia components where the fit and warranty make sense, and quality aftermarket parts where they outperform. We explain the choice before we make it.
- 6
We document the result and back it. Every job ends with a photo record of the completed work under Clause 4 of the Haven Standard, and it’s covered by our 365-Day Done Right Promise. If it’s not done right, we make it right.
What Olympia Chimney Chimney Cap & Crown Costs in New York

- Full crown tear-out and repour with drip edge: $1,200 to $1,800, depending on crown width and chimney height.

Why New York Homeowners Call Level Two Chimney New York for Olympia Chimney Work
We’re not a manufacturer’s service line. We’re a New York chimney company that’s been up on New York roofs since 2009, and we’ve completed more than 38,000 chimney inspections and cleanings in that time. Corrine Halstead, our owner, learned the trade through the building trades program at Bronx Community College and has spent the better part of two decades reading flue liners and writing repair estimates across the city, including years of work on older brownstones near Prospect Park in Brooklyn.
When an Olympia cap or crown fails, we document exactly what we see with a camera, price the fix in writing before we start, and back the work with our 365-Day Done Right Promise. We also stock and source materials beyond Olympia, including DuraFlex liners, HeatShield resurfacing, and Gelco products, so if an Olympia crown repair reveals liner trouble further down, we can address it that day rather than rescheduling. The camera doesn’t argue with you, and neither does the price sheet.
FAQs

It shouldn’t, as long as the work doesn’t alter the underlying listed appliance or liner system. As an independent Olympia Chimney service provider, we’re careful to work within the original design. When a failure is a known manufacturing issue, we’ll tell you to pursue a warranty claim first, and we’ll document the condition with photos you can send to Olympia.
In most cases, yes. We keep the common Olympia cap sizes in stock and can usually source specific model replacements within a few days. If your cap is an older discontinued Olympia series, we’ll show you a quality aftermarket equivalent and explain the difference in fit and warranty before we order it.
It depends on what the camera shows. Hairline surface cracks in a structurally sound crown can be sealed and coated. Cracks wider than a quarter inch, or any cracking that follows the flue tile, usually mean moisture has been working into the chimney structure, and that’s when we recommend a full tear-out and repour. We’ll show you the footage and let you decide with the price in hand.
Most cap and crown work is scheduled within a few days of the camera inspection, and the work itself is usually done in one visit. Weather, roof access, and parts availability can shift a schedule, but we’ll give you a written confirmation and a named tech before anyone shows up. Call (551) 213-5548 to get on the calendar.
Water gets into the chimney system. From there it’s a slow, predictable sequence: eroded mortar joints, spalled brick, a rusted damper, and eventually a damaged flue liner and a chimney fire or carbon monoxide risk. The cap and crown are your first line of defense against all of it. If a camera inspection shows the problem is still contained, we’ll say so plainly and tell you honestly how long you can safely wait. Call (551) 213-5548 for an exact assessment, estimates are free.
