Mount Baker, King County
A Mount Baker cap runs $235 to $850 fitted, the low number being stock stainless on one flue within easy reach. A cap that covers two or three flues on one crown, a made-to-measure size, or a tall stack that needs more ladder work moves toward the top. We measure first and order second, so the cap fits the tile it sits on.

Most of Mount Baker's older houses went up between 1905 and 1929, according to the city's context statement. On a house that old, one stack sometimes holds more than one flue, and what each flue serves may have changed since it was built. Before choosing a cap we find out what each one serves today. ZIP 98144 reaches beyond Mount Baker into north Beacon Hill and further north; there, utility gas is the primary heat for 32.7 percent of homes and oil in 2.2 percent, by the 2020 to 2024 census survey. A flue serving a gas or oil furnace needs a cap that does not restrict its exhaust, and that rules out some fine-mesh screens meant for wood fires.
Between the Canadian border and Seattle, lowland rain totals 32 to 35 inches yearly, the Western Regional Climate Center says, delivered mostly on south and southwest winds in the wet months. WeatherSpark's reading of Seattle's records points the same way, and notes that south-facing chimney faces in neighborhoods like Mount Baker take most of the wind-driven rain.
For a cap, that means the lid has to overhang far enough to stop rain coming in at an angle, not just falling straight down. On a stack that stands clear of the roof on the slope toward the water, we choose a lid with a wider skirt and fasten it on all four sides, because a cap that rattles loose in October stays loose all winter.
Every chimney cap installation we do in Mount Baker includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowSeattle's code (R1003.9.1) calls the slab on top of the brick a cap too: stone, metal or poured concrete, pitched so rain runs off, with a drip edge, kept apart from the liner tiles by a sealed break joint. Masons call that piece the crown. The metal rain cap mounts above that, and where it carries a spark arrestor, R1003.9.2 requires a screen whose net open area is at least four times the flue outlet. We check both before we leave: a crown that holds water will rot the best cap's fasteners, and a screen that is too small chokes the draft.
We note how many flues the crown carries, what each one serves now, and their outside dimensions.
Single or multi-flue, standard or made to measure, with a screen size that suits the fuel.
Stainless screws into the flue tile, or anchors set into the crown for a cap that spans several flues.
With a smoke test or the appliance running, we confirm the cap does not slow the exhaust, then send the photos.

Oregon State University Extension's plant pathologist makes a point that fits Mount Baker's wooded ravines: cleaning does not keep moss away unless the surroundings change. Under a canopy, a cap screen collects needles and seeds, and the mat stays damp. Seattle stays in its wet season from October 10 until April 30, per WeatherSpark, which leaves that mat damp most of the time.
A blocked screen slows the draft and can push smoke back into the room. Where trees hang over the roof, we fit a cap with a larger screen area than the minimum, and we suggest a look at it each autumn once the leaves are down.
Mount Baker is a Seattle neighborhood laid out in 1907 as the Mount Baker Park Addition, on the lakeshore, with houses built mostly in two waves, 1905 to about 1920 and then 1920 to 1929, a good share of them designed by Seattle architects. We work every part of it — the Mount Baker Park Addition, the York Addition included.

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.
Not necessarily. A multi-flue cap fastens to the crown and covers both, and it shelters the crown too. It costs more than one single cap, so we price both options.
It can help when rain wetting the soot is the cause. If the smell continues, the flue probably needs sweeping, which is a separate job.
We show you the photo and quote the crown repair separately. A full inspection is not required for a cap, but if you want one it is $99 plus tax, credited to any quote you then approve.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
