Fremont, King County
A chimney cap installed in Fremont costs $265 to $850. One stainless cap on one standard flue tile, reached from a roof of moderate pitch, is the $265 job. The high end is a cap made to measure for an odd-sized or tile-less flue, or a single large cover spanning two or three flues on the same crown. Height and pitch matter as well, since reaching the top of a high chimney above a sharp pitch is slow, roped work. We measure on the roof first and order or build the cap to that measurement.

Fremont climbs north from the Ship Canal, and its houses are stacked up that slope on lots laid out in 1888. The house types recorded by the city's survey range from late-Victorian cottages and American Foursquares to Craftsman bungalows, Tudor Revival houses and, later, Minimal Traditional and Ranch houses. With that many building periods on one hillside, we take nothing about the top of a stack for granted. A flue may end in a clay tile standing proud of the crown or sit flush with it, and a cap bought by nominal size at a hardware store only fits the first kind.
Seattle's windier months run from about October 15 to April 24 on WeatherSpark's calendar, with December the windiest. The city's emergency management office adds the upper bound: the big Puget Sound storms blow at a sustained 60-70 mph, gusting to 90. Fremont's southern edge is open water: Lake Union and the Fremont Cut.
A cap that merely grips the top flue tile by friction is the one found in the yard in January. We fasten into the tile's sides with stainless screws, or into the crown with masonry anchors when the tile is cracked or absent, and we check the tile first: a clamp is only as firm as the clay it squeezes. Snow counts too: the Portage Bay gauge on the lake side measured 22.5 inches in December 1996, a load a flat lid has to carry without folding.
Every chimney cap installation we do in Fremont includes:

Book nowA missing cap leaves the flue open to three things: rain, animals and downdrafts. Seattle's residential code does not oblige every chimney to carry a spark arrestor, but where one is fitted, R1003.9.2 sets the mesh. It has to stop a half-inch sphere and let a three-eighths-inch one through, and the screen's clear openings must total four flue-outlet areas or more. Undersize the cap, or set its lid too close to the tile, and the draft is throttled until the fireplace smokes. The State Fire Marshal's Office, writing on home heating in September 2026, names the cap in one breath with a hearth screen, glass doors and alarms that work.
On the roof we write down how many flues there are, each tile's outer size and how far it stands proud of the crown.
Stock stainless where it fits; a made-to-measure cover where the opening is irregular or shared.
Screws through the cap's clamp or anchors into sound crown, never adhesive alone.
A draft check follows the last screw, then the photographs.

A stainless cap, by one Seattle sweep company's published estimate, is good for 15-20 years and beyond; galvanized, for 5-10. That is their figure, not a guarantee from us, but it is the reason the caps we fit are stainless.
A cap can be fitted without one. Should the crown or tile prove too damaged to hold a cap, we stop and offer an inspection instead ($99 plus tax); hire us for the repair it identifies and the repair bill swallows that fee.
Yes. A multi-flue cap sits on the crown and shelters all the openings under one lid. It costs more than a single cap and protects the crown itself from standing water.
