Seward Park, King County
A new chimney cap in Seward Park costs between $235 and $850, installed. The low end is a stainless cap with mesh over one round or square flue. Two or three flues sharing one lid, a custom-bent cap for an irregular crown, or a cap with its own top damper cost more. We measure the flue tile on the roof first; a cap ordered from a photo seldom fits.

Seward Park was named after the park on its peninsula, which the city bought in 1911 and dedicated to William H. Seward, per HistoryLink and Wikipedia. More than a century on, that ground still holds a large stand of old forest, and its canopy reaches the streets around it. For a chimney top, trees mean three things: needles and cones dropping into an open flue, birds and squirrels looking for a sheltered hollow, and embers rising toward branches. A capped flue with a proper screen deals with all three at once.
Wikipedia gives the neighborhood the lake for its eastern and northern boundary. In WeatherSpark's Seattle record a southerly wind prevails for roughly nine and a half months, giving way to a northerly one only from early July into late September. We know of no measurement of how that wind behaves on this particular shore, so we will not claim one.
Citywide numbers are enough to shape the job. The city's emergency managers say wind starts damaging structures at about 32 miles an hour. A cap that is only pressed onto the tile can be lifted at far less than that, and an open flue in a driving southerly rain takes water straight onto the damper. Every cap we set is mechanically fastened.
Every chimney cap installation we do in Seward Park includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowSeattle does not leave caps optional. The city's house code, at R1003.9.1, calls for a top of stone, metal or concrete on any masonry chimney; it has to pitch so rain runs off, overhang with a drip edge, and float free of the liner tiles on a sealed joint. With a spark arrestor, R1003.9.2 requires mesh whose open area is four times the flue outlet or more, made of wire no lighter than galvanized 19-gage or stainless 24-gage. We follow those numbers, so the cap that keeps sparks in does not also choke the draft.
Each flue is measured across the tile, and the crown is checked for cracks that would undercut a crown-mounted cap.
Single-flue or multi-flue, standard or custom, with the screen area worked out against the flue size.
The cap is secured with stainless hardware so a gust cannot lift it off the tile.
Where the fireplace can be lit, we confirm smoke still leaves cleanly with the screen in place.

A spark screen under a big canopy collects everything the trees let go of. On roofs bordering the park's 120 acres of old growth, moss can also climb the crown and anchor itself around the cap's legs. Oregon State University Extension's roof guidance applies to that crown as well: clean first, then treat, and expect the moss back unless shade and damp are reduced.
When we fit a cap we scrape the crown clean before fastening, so the cap does not sit on a sponge. Afterward the screen is easy to brush from the roof; under heavy trees it makes sense to clear it at the yearly check rather than wait for smoke to back up.
Seward Park is a Seattle neighborhood named for the 300-acre park on its peninsula, on the lakeshore, with homes in a ZIP code area (98118) where about six in ten housing units are detached houses and the median build year is 1968.

Four steps, each one on paper — so you always know what happens next.
Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
Too fine a screen clogs and starves the fire of draft. The code sets a minimum open area, and we size to it; a cap screen still needs clearing every so often under heavy trees.
No. Gas vents usually carry a cap listed with the appliance. We fit masonry flue caps and tell you if a gas termination looks wrong.
Not for a simple cap. If we see crown or flue damage while measuring, we recommend the $99-plus-tax inspection, which is deducted from whatever repair you agree to.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
