Olympia Chimney Chimney Cap Installation Nationwide

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

We stock and install Olympia Chimney-compatible chimney caps across Kirkland, typically running $340-$620 installed depending on flue size and whether your crown needs resealing. Most replacements are completed in under two hours, and we carry common Olympia Chimney cap sizes on every truck. You’ll usually discover the cap has failed when water starts dripping down the flue during a November storm, or when a neighbor spots rust stains on your chimney chase that weren’t there last season.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures caps for their stainless steel liner systems, primarily the 304 and 316 alloy flue lines, plus their direct-vent and B-vent gas appliance caps. The critical match point is your flue diameter, not the cap’s outer dimension. A 6-inch inner-diameter Olympia flue takes a 6-inch cap collar; the overhang beyond that varies by series. Check the stamped rating plate on your flue liner, usually visible at the top of the chimney or inside the firebox throat. If the plate’s corroded, measure the flue opening directly with a tape measure across the inside edge.

We source Olympia Chimney caps through Haven’s buying network, but we also stock Gelco and Famco equivalents when the OEM lead time stretches past what Kirkland’s rainy season allows. The aftermarket caps we use match 304 or 316 spec and carry the same mesh spark-arrestor rating. One compatibility gotcha: Olympia’s older pre-2015 caps used a slightly narrower mesh gauge that some current municipal codes in King County no longer pass. We check that against your jurisdiction before quoting.

Signs Your Olympia Chimney Chimney Cap Is Failing

• Rust streaks running down the chimney exterior. Olympia Chimney caps are stainless, but the spot-welded seams and the mesh screen are where salt-laden Kirkland air first attacks. Once the weld point corrodes, the cap tilts and channels water directly onto the crown instead of shedding it.
• Water in the firebox or rust on the damper. A cap that has shifted even half an inch off-center creates a direct funnel. In homes near Juanita Beach where we work regularly, the wind-driven rain finds that gap faster than you’d expect.
• Birds or squirrels audible in the flue. The mesh on an Olympia Chimney cap is finer than standard hardware-store versions. When it separates at the seam or a corner pops, small animals push through. We pulled a nest from a Bridle Trails home last March where the cap mesh had fatigued at exactly the weld point.
• Sparks visible from the roof during a fire. The spark-arrestor mesh degrades before the cap body does. In Kirkland’s wooded neighborhoods, this is the failure mode that matters most for wildfire season compliance.
• The cap is visibly tilted or missing after a windstorm. Olympia Chimney caps secure with stainless straps or a compression fit depending on the series. The strap-style mounts fatigue in our wet-freeze cycles; we’ve replaced caps on Finn Hill homes where the strap snapped clean after three winters.

Replacement Cost & What’s Included

The range depends on three things: flue diameter, whether we need to fabricate a custom mount for an older Olympia series, and crown condition. Every quote is written before work starts, Clause 1 of the Haven Standard. The cap carries a 10-year material warranty; our installation is covered by the 365-Day Done Right Promise. We photograph the finished mount and add it to your documented record under Clause 4.

DIY or Call Us?

You can safely check whether your cap is tilted or missing from the ground with binoculars, and you can measure your flue diameter from inside the firebox if you’re comfortable on a step stool. What you cannot safely do is work at chimney height on a Kirkland roof. Our crews carry fall-arrest gear and ladder stabilization as standard; the slope on many Juanita and Kingsgate roofs is steeper than it looks from the driveway.

More importantly, a cap that has leaked for even one season often hides crown damage or flue liner deterioration that only a camera inspection reveals. We’ve had homeowners in Kirkland install a new cap themselves, then call us six months later when water was still getting in. The cap was fine; the crown beneath it had cracked. The camera doesn’t lie, and neither does the invoice. If you want to know what you’re actually dealing with before spending money, call us at (425) 642-3485. The inspection and written quote are free.
