Olympia Chimney Chimney Cap Installation Nationwide

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

An Olympia Chimney chimney cap installation in Ewing typically runs between $280 and $520 installed, depending on flue size and whether your crown needs patching before the cap goes on. We stock Olympia Chimney-compatible caps in common sizes for New Jersey masonry chimneys and can usually install within a few days of your call, with camera documentation of the flue condition before we start. Most Ewing homeowners discover their cap has failed when water starts dripping down the flue during heavy rain, or when a neighbor spots rust stains running down the brick from the roofline.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures caps across several product lines, and matching the right series matters for both fit and venting performance. The Olympia Chimney Draft King and Weatherbeater series are the two we encounter most often in Ewing homes built between 1960 and 1995, particularly the DK-13 through DK-17 round-base models and the WB-series multi-flue caps found on larger colonials near Mountain View Road. The label is usually stamped on the underside of the existing cap’s lid, though after twenty New Jersey winters that stamp can rust to illegibility.

When the label is gone, we measure the flue tile outer diameter to the sixteenth of an inch and check the crown overhang. Olympia Chimney’s round-base caps require a minimum 1-inch crown lip for proper mounting; without it, we need a slip-in model with set screws or a crown build-up first. We are an independent service provider, not affiliated with Olympia Chimney, and we carry both OEM-spec caps and professional-grade equivalents from Gelco and Copperfield that match Olympia’s 304 stainless and galvanized specs. For coastal-exposed Ewing homes near the Delaware, we typically recommend the heavier-gauge 304 stainless over galvanized, since the salt air accelerates rust-through by roughly half the expected lifespan.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust-colored staining on the brickwork below the crown. Olympia Chimney galvanized caps begin showing surface rust at the lid seams after 8-12 years in Mercer County’s freeze-thaw cycles. Once the rust reaches the interior, it drips onto the crown and runs down the brick, leaving tracks that darken with each season.
• Water in the firebox after rain, even with the damper closed. A warped or missing lid on an Olympia Chimney Draft King allows direct water entry. The Draft King’s hinge pin is the failure point; when it seizes or snaps, the lid hangs crooked or falls off entirely, and driving rain enters the flue unimpeded.
• Bird or squirrel noise in the flue during daylight hours. The mesh screen on Olympia Chimney caps is 5/8-inch weave, which blocks most animals when intact. A single bent wire from storm damage or ice loading creates an entry point. In Ewing, we see this most often after March ice storms, when freeze-thaw opens gaps at the mesh-to-frame joint.
• Spalling brick or deteriorated mortar at the chimney top. A missing or leaking cap lets water soak the crown and saturate the top course of brick. In older Ewing homes with soft historic brick, this accelerates dramatically; we’ve repointed crowns where the cap failed three years prior and the owner hadn’t noticed until pieces of brick started landing in the yard.
• Downdraft smoke spillage on windy days. The Olympia Chimney Weatherbeater’s design relies on its directional lid to deflect wind. When the lid is dented or the cap sits too low after settling, the wind can force straight down the flue. This is especially pronounced on Ewing’s east-facing exposures toward Scotch Road, where prevailing winter winds hit the chimney full-on.

Replacement Cost & What’s Included

What drives the range: flue diameter (13-inch costs less than 17-inch), material grade, and whether we need to fabricate a mounting adapter for an irregular crown. Every cap installation includes a Level-2 camera inspection of the flue, photos you can see, and a plain-English verdict on whether anything else needs attention. The price we quote is the price on the invoice. Work is covered by our 90-Day Done Right Promise, in writing, no arguing.

DIY or Call Us?

An owner can safely check three things from the ground with binoculars: whether the cap lid is present and level, whether the mesh is intact without visible gaps, and whether rust stains are running down the brick. Do not climb the roof to confirm. Chimney work at height on a pitched roof is genuinely dangerous, and a cap that has been loose for any length of time may have compromised the crown surface beneath it, creating a false step.

Where DIY goes wrong: the cap that looks like a simple swap often isn’t. Crown deterioration hidden beneath the old base, improperly sized flue tiles, and stripped mounting holes in the crown all require on-the-spot decisions about repair sequencing. We’ve retrieved more than one homeowner’s dropped cap from the gutter, and we’ve reinstalled caps that were mounted with the wrong hardware, which then worked loose and rattled for two winters before the owner called. If the flue is right, the fire takes care of itself. Getting up there to verify that is our job, not yours.
