Olympia Chimney Chimney Cap Installation Nationwide

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

We stock and install Olympia Chimney-compatible chimney caps across the Olympia area, with most residential installations running $285-$495 installed depending on flue size and whether your crown needs prep work. Most jobs we book are completed same visit once the cap is on the truck. Homeowners usually figure out something’s wrong when water starts dripping onto the firebox floor after a hard rain, or when they spot rust streaks running down the brick from a cap that’s lost its galvanizing.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps fit the brand’s factory-built metal chimney systems, not masonry flues, and the critical match is your chimney’s outer diameter and flue count. The common residential lines we see around Olympia are the 6-inch and 8-inch diameter double-wall systems, with model numbers stamped on a metal tag where the chimney exits the chase or attic space. That tag lists the UL listing and nominal diameter; the cap has to match exactly or you’ll get a sloppy fit that leaks at the collar.

We carry both OEM Olympia caps and Gelco equivalents sourced through our Haven buying network. The OEM part guarantees exact collar depth and spark-arrestor mesh spec, but Gelco’s galvanized and stainless options often outlast the factory part in our wet South Sound winters at a lower price point. If your Olympia system is more than 15 years old, check whether the flue has shifted in its chase; a cap that fit loosely when new may need a custom adapter now. Corrine Halstead and our crew have measured enough of these on roofs near the Capitol Campus to spot the chase-settle pattern before the ladder comes down.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains on the chimney chase or siding. Olympia’s factory galvanized caps hold up reasonably well, but once the zinc layer wears through, the steel underneath rusts fast in Olympia’s marine climate. Those orange streaks mean the cap is bleeding metal; replacement is usually months overdue.
• Water dripping into the firebox or on the hearth. A cracked or missing cap collar lets rain run straight down the flue. In Olympia’s wet season, that water pools on the smoke shelf and can wick into surrounding framing.
• Debris or bird nesting material visible from below. The spark-arrestor mesh on Olympia caps clogs with creosote or corrodes open; either way, squirrels and starlings get in. We pulled a nest from a Westside Olympia flue last March that had been blocking the flue for two burning seasons.
• Cap is visibly tilted, loose, or missing entirely. Wind gusts off Puget Sound can torque a poorly secured cap; we’ve found them in shrub beds after January storms. The mounting brackets on older Olympia systems fatigue at the screw holes.
• Downdraft smoke or odd fireplace odor. A cap with a damaged or missing wind-directional hood loses its ability to deflect crosswinds. Your fireplace smokes back into the room on windy days, or you smell damp ash even when the system’s cold.

Replacement Cost & What’s Included

What drives the range: flue diameter, material grade, and whether we need to build up or grind down the crown surface for a clean seat. Every quote is written before work starts, under Haven Standard Clause 1. The cap carries a 10-year material warranty; our labor is covered by the 365-Day Done Right Promise. You’ll get photos of the old cap, the seated new one, and the smoke test - Clause 4 of the Haven Standard requires the photo record.

DIY or Call Us?

You can safely check whether your cap is loose or missing from the ground with binoculars, and you can read the model tag if it’s accessible from the attic. Don’t climb the roof. Olympia chimney systems are lightweight metal and the chase framing can be spongy near the top; combine that with our moss-slick shingles and you’ve got a fall risk that outmatches any savings.

Installation itself is straightforward for us because we carry the adapters and sealants that don’t come with the retail box. Getting the collar sealed with the right high-temp silicone, torqueing the brackets without stripping the chase-mounted threads, and confirming draft with a smoke pellet - that’s the difference between a cap that lasts and one that leaks in the first winter. Call (360) 464-2015 and we’ll get you a written price before anyone sets a ladder.
