Olympia Chimney Chimney Cap Installation Nationwide

Olympia Chimney Chimney Cap Installation: The Rockville Centre Owner’s Guide

Olympia Chimney chimney cap installation in Rockville Centre typically runs $280-$520 for most residential flues, with standard stainless steel caps installed in a single visit. We stock Olympia Chimney-compatible caps on our trucks, including the 13-by-13 through 17-by-21 inch range that covers most pre-fab and masonry setups in this area. Most Rockville Centre homeowners realize their cap has failed after finding rust streaks on the chimney breast, hearing animals in the flue, or noticing water spots on the ceiling near the fireplace after a nor’easter blows through.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps are not one-size-fits-all, and the compatibility gotcha most owners miss is the difference between their round and oval termination lines. The Olympia 316Ti stainless series uses a proprietary collar depth, roughly 2.5 inches, that sits deeper into the flue tile than standard aftermarket caps. If you’ve got an Olympia factory-built system from the 1990s or 2000s, check the stamped model tag on the chase cover or the metal data plate inside the firebox. The prefix matters: OL-round caps won’t seat properly on OV-oval flues, and forcing it leaves a gap that funnels water straight onto the smoke shelf.

We carry both OEM Olympia caps and equivalent-grade aftermarket from Gelco and Copperfield. For most Rockville Centre homes, the aftermarket equivalent matches the 316Ti spec and carries the same lifetime warranty against rust-through. The only time we push OEM is when the original cap was part of an engineered system with a specific UL listing, which matters for insurance compliance on newer construction near the Long Beach border.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains bleeding down the chimney face. Olympia’s 316Ti is corrosion-resistant, not corrosion-proof. Once the salt air from Long Island Sound gets past a dent or loose seam, the cap corrodes from the inside out. We see this most on south-facing caps that take the full brunt of winter storms.
• Water in the firebox or damp odors after rain. A cap with a cracked hood or separated mesh screen lets water track down the flue liner. In Rockville Centre’s older homes near Hempstead Avenue, that water hits the smoke shelf and soaks into the back wall of the firebox.
• Bird or squirrel noise in the flue. The mesh sides on an Olympia cap are 5/8-inch weave, fine enough to stop starlings but not wasps. When the mesh pulls away from the frame, anything larger gets in. We pulled a nest out of a Merrick Road home last spring that had been building since October.
• The cap is visibly tilted or missing entirely. High wind gusts off the Atlantic can shear off a poorly secured cap. If yours is hanging by one corner, the mounting brackets have fatigued. That cap is coming off in the next storm, and it may take flue tile with it.
• Spalling brick or deteriorated mortar on the chimney top. This is the delayed symptom. Water that gets past a failed cap freezes in the crown and brick joints. In Rockville Centre’s freeze-thaw cycles, that damage compounds every winter. The cap was the cheap fix; now you’re looking at crown work too.

Replacement Cost & What’s Included

The range depends on three things: cap size, whether we need to fabricate a custom adapter for an older Olympia collar, and what the crown looks like underneath. We photograph everything before we quote. No surprises on the bill. The 90-Day Done Right Promise covers the installation, and the cap itself carries a lifetime rust-through warranty from the manufacturer.

Current standing offer: $50 off any repair over $250, which most cap replacements qualify for. Seniors and veterans receive a permanent 5% discount.

DIY or Call Us?

Here’s what you can safely check from the ground: look for visible tilt, missing mesh, or rust streaks. Use binoculars. Do not climb the roof. Chimney cap work involves working at height on a surface that may be slick with algae or dew, and the mounting brackets often require a hammer drill or rotary tool to seat properly in masonry. A cap that is not square to the flue and torqued evenly on all corners will leak, rattle, and eventually fail again.

We bring the right cap, the right fasteners, and the right sealant for your specific Olympia setup. Most jobs take under 90 minutes. Call (631) 498-8835 and a live person will pick up, 24 hours a day.
