Olympia Chimney Chimney Cap Installation Nationwide

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

An Olympia Chimney chimney cap installed by Hearthstone Chimney Co. in Huntington typically runs $280-$520 for standard single-flue models and $480-$890 for custom multi-flue or chase cover replacements, with most jobs completed in one visit. We stock Olympia Chimney-compatible caps in common sizes and can measure, match, and install without a second trip for most Huntington homes. You’ll usually know the cap is failing when you spot rust streaks on the masonry, hear water dripping in the flue during rain, or find debris, nests, or downspraw in the firebox.

We’ve replaced more chimney caps on West Neck Road and Southdown Road homes than we can count, and the pattern is always the same: a cap that looked fine from the ground has been letting salt air and nor’easter rain work underneath for years. Russell Haines, our owner, has been reading these failures for over twenty years. He’ll tell you straight whether you need a full replacement or if the existing mounting points can be salvaged.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures caps across several product lines, and the right match depends on whether you have a single-flue terra cotta pot, a multi-flue chimney crown, or a factory-built chase top. The most common we see in Huntington are the Olympia single-flue galvanized or stainless caps (typically 8″×8″ to 13″×13″ flue openings) and the Olympia chase cover replacements for pre-fab chimneys, which run 24″×24″ up to 48″×48″ and require precise corner measurements to the quarter-inch.

To identify your cap, look for the Olympia stamp on the mesh screen frame or the underside of the lid. If the stamp’s rusted away, measure the flue tile’s outside dimensions and note whether your chimney has a crown-mounted or flue-top installation. Here’s where DIY ordering goes wrong: Olympia’s “universal” fit caps have a 1.5-inch overhang tolerance that works fine in dry climates, but Huntington’s freeze-thaw cycles and coastal wind exposure demand a tighter fit. We typically source OEM Olympia caps for exact-match jobs, or we can fabricate a heavier-gauge equivalent from Gelco or Copperfield when the original spec is undersized for Long Island conditions.

One compatibility gotcha we’ve learned the hard way: Olympia’s pre-2015 galvanized caps share bolt patterns with their stainless line, but the gauge differs. A stainless cap dropped onto galvanized mounting brackets will flex in high wind and eventually crack the corner welds. We check this every time.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains running down the chimney face. Olympia’s factory galvanized caps carry a 10-15 year coating warranty, but Huntington’s salt air accelerates edge corrosion. Once rust bleeds through, the metal underneath is thinning fast. Water follows those same channels into the mortar joints.
• Water dripping or puddling in the firebox after rain. This means the cap’s lid is cracked, the mesh has separated from the frame, or the mounting flange has pulled away from the flue tile. Even a gap the width of a pencil lets in surprising volume during a Long Island downpour.
• Bird nests, squirrel debris, or leaves in the flue. A properly seated Olympia cap has 5/8-inch mesh that blocks animals while letting smoke escape. If you’re finding material above the damper, the mesh is torn, corroded, or missing entirely. This is also a carbon monoxide risk if the blockage is partial.
• The cap is visibly tilted, shifted, or missing after a storm. Huntington’s coastal gusts hit 50+ mph several times each winter. Olympia caps use stainless steel tension screws or a base-mount flange; if either loosens, the cap becomes a wind sail. We’ve retrieved caps from neighboring yards after nor’easters.
• White efflorescence or spalling brick on the chimney exterior. This indicates chronic moisture intrusion, often from a cap that was never properly flashed or counter-flashed. The cap itself may look intact, but water is getting behind it and saturating the masonry. Left alone, this leads to freeze-thaw damage and costly repointing.

Replacement Cost & What’s Included

What drives the range: accessibility (steep roof pitch, height, Huntington village setback requirements), whether the existing flue tile is cracked and needs repair before mounting, and whether we find hidden water damage once the old cap is off. We photograph everything and show you before we proceed. No surprises on the bill. Every cap installation carries our 90-Day Done Right Promise - in writing, no arguing. If it leaks, shifts, or fails, we come back.

Hearthstone Chimney Co. is an independent service provider; we are not affiliated with Olympia Chimney. We source their caps through authorized distribution and also stock quality equivalents from Gelco, Famco, and Copperfield when the job calls for it.

DIY or Call Us?

There’s a short list of things a homeowner can safely check from inside the house: shine a flashlight up the flue to spot debris, look for daylight where the cap should block it, and note any water in the firebox after rain. That’s it. Everything else happens on the roof.

Chimney cap replacement involves working at height on a pitched surface, often with Huntington’s clay tile roofs that are slick even when dry. The fasteners are typically seized with rust. The flue tile itself is brittle; torque a screw wrong and you’ve turned a $300 cap job into a $1,400 flue repair. We’ve also seen homeowners install caps with insufficient clearance from the flue opening, which can restrict draft and push carbon monoxide into the house. A clean chimney isn’t a luxury - it’s just the job done right.

If you’re comfortable on a ladder and have solid footing, you can measure your flue opening and call us with the dimensions. We’ll tell you whether it’s a stock item or needs fabrication. For everything else, our background-checked, uniformed technicians carry the tools, the fall protection, and the experience to do it once. Most jobs are completed in a single visit.
