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 Deer Park Owner’s Guide
We stock and install Olympia Chimney chimney caps across Deer Park, with most installations running between $285 and $520 depending on cap size and liner fit. We carry the common sizes on the truck, so most Deer Park jobs are done in a single visit. The typical call starts the same way: someone notices rust flakes on the roof, hears rain in the flue during a storm, or finds a bird in the fireplace. The cap was the quiet part on top of the house, right up until it wasn’t.
What makes the Olympia Chimney cap worth getting matched correctly is the brand’s own sizing system. Olympia builds around their liner diameters, not generic flue tile measurements, so a cap that fits a competitor’s flue won’t necessarily seat right on an Olympia liner. Get it wrong and you’re buying the same fix twice. Wendell Pike has been up on enough Deer Park rooftops over the last two decades to tell you which caps fit their liners the first time, because he’s already made the mistake of trusting the tape measure the guy at the counter handed him. That’s a lesson he gives away free.
Key takeaways:
- Olympia Chimney caps are sized to their liner diameters, not universal flue dimensions.
- Most Deer Park cap replacements cost $285 to $520 installed, parts and labor included.
- We carry the most common Olympia-compatible cap sizes on the truck.
- The 90-Day Done Right Promise covers the installation, in writing, on every job.
Which Olympia Chimney Models This Applies To
Olympia Chimney makes a range of liner systems and venting products, and their caps follow that product family logic. The most common ones we handle in Deer Park are the caps that ride on their stainless steel chimney liners, including the standard round cap assemblies meant for gas, oil, and wood venting. Some Olympia caps come pre-installed as part of a liner kit, which matters because a failure there means you’re replacing the cap component, not the whole liner assembly. We’ll tell you which one you need after putting eyes on what’s actually up there.
The compatibility gotcha with Olympia is this: their caps are engineered for their specific liner collar diameters. Measure a section of liner and order a cap based on that number alone, and you may end up with a cap whose base collar sits too loose or too tight, especially if the liner has ovaled over time or wasn’t to spec to begin with. We match by taking the actual liner measurement from the rooftop, not from the manufacturer’s catalog photo. Aftermarket caps often work fine on Olympia liners, but only if the collar tolerance is right. We stock trusted alternatives like DuraFlex, Gelco, HeatShield, and Copperfield, and we’ll tell you when a less expensive aftermarket cap will outlast the OEM part in Long Island weather.
Top Hat Chimney is an independent chimney service company, not affiliated with Olympia Chimney. We install and service their products because we’ve seen which ones hold up and which don’t. That’s the honest starting point: we’re not pushing a brand, we’re fixing a chimney.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- You hear rain or dripping inside the flue. The cap’s rain guard has corroded through or separated from the collar. On an Olympia cap, the seam between the mesh body and the top plate is usually the first place water gets in.
- Birds, squirrels, or nesting material show up in the fireplace or at the clean-out door. The mesh screening has torn or pulled away from the frame. Once the mesh fails, the cap is no longer excluded - it’s an open doorway. Olympia’s older mesh was stainless, but even stainless gives out eventually, and when it does, the whole cap needs replacing, not patching.
- Rust stains running down the flue tiles or the chase top. The cap base or collar has rusted and the rust is now bleeding down onto the surrounding brick or siding. This is the sign we see most often in Deer Park after the salt air and winter freeze cycles do their work. A rusted collar also means the cap is no longer seated tight, which means it’s rocking in the wind and making the next problem worse.
- The cap is loose or tilting. Walk outside and look up. If the cap leans or you can see a gap between the collar and the liner, the clamping bolts have backed off or the collar has stretched. That’s not a re-tighten job. The seal is compromised, and a tilted cap lets rain run down the inside of the liner, which is where the real damage starts.
- You notice a metallic rattling sound coming from the chimney during high wind. That’s a cap that’s rusted enough to lose its structural tension. The top and base are vibrating against each other. Eventually the wind will take the whole assembly off, and a tossed cap is a surprise nobody wants.
Replacement Cost & What’s Included
Plan on $285 to $520 installed for an Olympia Chimney-compatible cap replacement in Deer Park. The spread comes down to three things: cap size (larger liners need bigger, pricier caps), the condition of the liner or chimney crown you’re mounting to, and whether we’re matching OEM specs or switching you to a better aftermarket fit. You’ll know the exact number before a single tool comes off the truck, because our pricing is set up front and the figure we quote is the figure on the invoice.
Every cap installation includes removal of the failed cap, a close inspection of the liner top for hidden rust or ovaling, correct alignment and clamping of the new cap, and a water-tightness check. The work is backed by the 90-Day Done Right Promise, which is a written guarantee: if the cap isn’t right, one call brings Wendell or his crew back at no charge. No fine print, no round-robin with a phone tree.

DIY or Call Us?
Here’s the straight version. Working on a chimney cap means being on a roof, and that’s the reality most weekends don’t prepare you for. A steep pitch over a two-story colonial in Deer Park is not a ladder job for a Tuesday evening. The back edge of the cap, the tension in the clamping bolts, and the way the liner gives underfoot are all unknowns until you’re already up there. That’s how people end up with a twisted knee or worse and a half-finished cap job. If you’re going to check anything yourself, check from the ground with binoculars: look for rust, tilt, missing mesh, or daylight between the cap and liner.
What we’d rather you do is call us. We’ll come out, get on the roof safely, show you what’s what, and tell you honestly if the cap needs replacing or if it has another year in it. If it doesn’t need doing, we’ll tell you that too. Photo and camera evidence come with every inspection, so you’re never asked to trust a verdict you can’t see. Call (631) 214-2108 and we’ll get you a free estimate.
FAQs
Realistically, ten to fifteen years in this climate, and often less if the cap takes direct morning sun and salt air off the coast. The stainless mesh fails first, then the collar. A cap that gets inspected once a year with the rest of the chimney will give you full warning before it goes all at once. If yours is past year ten and you’re seeing rust, start planning the replacement now rather than waiting for the leak. Call (631) 214-2108 for an exact look at your cap, free.
Not usually, and we won’t pretend otherwise. Once the mesh tears or the collar rusts, the cap’s structural job is done. Patching a rusted collar is a temporary bandage that fails again, often within a season, and the labor cost to do it twice exceeds the cost of doing it right once. We’ll tell you if a minor issue, like loose bolts, is fixable without replacement, and we’ll show you the rust or fatigue on camera so the call is yours to make. Call (631) 214-2108 for a plain-English verdict.
About 60 to 90 minutes on site for a standard Olympia-style cap on a straightforward chimney. That includes removing the old cap, checking the liner top, fitting and clamping the new cap, and confirming the seal. If the chase cover or crown needs minor patching, add a little time. Most Deer Park jobs are done in one visit because we stock the common cap sizes on the truck. Call (631) 214-2108 and we’ll give you a real arrival window.
We stock the most common Olympia-compatible cap sizes and aftermarket alternatives from DuraFlex, Gelco, HeatShield, and Copperfield. That means most replacements aren’t a two-week waiting game for a part to ship. If your liner calls for a size we don’t have on the shelf, we’ll have it in hand within a few days and let you know the timeline before you commit. Call (631) 214-2108 and we’ll confirm what fits your chimney.
