Olympia Chimney Chimney Cap Installation Nationwide

Olympia Chimney Chimney Cap Installation: The Brentwood Owner’s Guide

We stock and install Olympia Chimney-compatible chimney caps throughout Brentwood, and a complete cap replacement with installation typically runs $220 to $460 depending on the flue size and cap style. Most swaps take under an hour once we’re on the roof, and we keep the most common Olympia Chimney sizes on the truck so we’re not making you wait on a parts order. The usual way people find out their cap has failed is a rust stain bleeding down the chimney chase, or water pooling in the firebox after a heavy Long Island rain. Sometimes it’s a cap that’s simply gone, blown clean off in a nor’easter and never noticed until the first cold snap.

Which Olympia Chimney Models This Applies To

Olympia Chimney has been making stainless steel and copper caps for decades, and the good news is their sizing is straightforward once you know what to measure. Their standard line covers flue tile sizes from 6-inch round up through 13-by-18-inch rectangular, with the most common Brentwood installations being the 8-inch and 13-by-13 sizes on older masonry chimneys. The key compatibility gotcha is the base style: Olympia makes slip-in caps that seat inside the flue tile and bolt-on caps that fasten to the outside of the tile or a pre-existing crown mount. You cannot freely swap one for the other without modifying the crown or adding an adapter, and on chimneys where the flue tile has spalled or cracked at the top, a slip-in style often won’t seat squarely no matter how carefully you measure.

When it comes to OEM versus aftermarket for Olympia Chimney specifically, we’ll be straight with you: Olympia’s own stainless caps are well built and carry a solid warranty, but there are quality aftermarket equivalents from Gelco and Copperfield that match their dimensions precisely and often outlast the OEM mesh in coastal air. We’ll quote you the Olympia part and a comparable aftermarket option when one makes sense, and tell you honestly when it doesn’t. Top Hat Chimney is an independent local company, not affiliated with Olympia Chimney, and we’re just as happy installing the cap you bought yourself if it’s the right size and condition.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Water in the firebox or a damp smell after rain. This is the classic first sign. The cap’s job is keeping rain out of the flue, and once the hood rusts through or the screen tears, water gets a straight shot down into your fireplace.
• Rust stains running down the chimney chase or crown. That orange streaking means the cap’s steel is actively corroding. On Long Island, salt air accelerates this faster than inland areas, and once it starts, the cap has maybe two more seasons before it’s structurally gone.
• Debris and leaves inside the firebox or on the smoke shelf. A torn or missing screen mesh lets everything from maple leaves to acorns fall straight down the flue. We’ve pulled nests out of chimneys in Brentwood where the cap screen had a hole no bigger than a quarter.
• You hear birds or scratching from inside the chimney. A failed cap screen is an open invitation for starlings and squirrels, and once they nest, you’re either waiting out the season or paying for a removal plus a deep clean before the cap can be replaced.
• Visible rust-through or missing pieces on the cap itself. If you can see daylight through the hood from the ground, or the mesh is peeling away from the frame, it’s done. Don’t wait until it decides to leave on its own in the next storm.

Replacement Cost & What’s Included

For Brentwood homeowners, a full Olympia Chimney chimney cap installation generally falls between $220 and $460 depending on three things: the flue size, whether it’s a standard stainless cap or a custom-fit copper unit, and whether the existing crown is in good enough shape to accept the new base without additional work. A standard stainless cap for a single 8-inch flue usually lands around $220 to $280 installed. Larger custom caps and copper lids can push toward $400 or more. Every quote includes the cap, the proper mounting hardware, fastening, sealing, and cleanup, plus our 90-Day Done Right Promise on the labor. If the crown under the old cap is cracked or spalling, we’ll show you the camera footage and give you the crown repair quote separately. Nothing gets recommended that you can’t verify yourself.

DIY or Call Us?

There is a real safety line here, and we’ll be plain about it. Working on a chimney cap means getting on the roof with the flue right there, and on Long Island’s pitch, that means being comfortable on a ladder and on asphalt shingles. If you’re steady on your feet and the chimney is easily accessible, you can absolutely measure the flue yourself and even do a visual inspection from the ground or a safe ladder position. But the actual swap involves being up at the flue with both hands on the cap, often in wind, and we’ve seen enough near-misses to say this: if you’re not completely sure on a sloped roof, call us. The cost of a professional install is a lot less than a hospital visit, and we’ll do it right the first time.

If you’re handy but unsure, we’ll also install a cap you already bought. Call (934) 935-3847 and we’ll quote the labor alone.
