Mount Baker, King County
Chimney flashing repair in Mount Baker runs $325 to $1,500. Near the bottom: metal that is still good, just needing its failed sealant cut out and redone. Cutting new reglets into the brick, replacing the step and counter pieces all round, or adding a cricket behind a wide stack sits high. Before quoting, we trace the leak: water that shows up near the chimney does not always come from the flashing.

Volunteers who prepared the 2017 historic nomination for the Mount Baker Park Addition profiled more than 800 houses, Friends of Mount Baker Town Center reported, and the list of styles runs from American Foursquare and Craftsman through Tudor Revival, Swiss Chalet, Mission Revival and Spanish Eclectic. Roof shapes and roofing vary just as much. That is why we do not keep one stock flashing detail for this neighborhood: the metal has to be bent and lapped to suit the pitch, the roofing and the brick of the house in front of us, and color-matched where the chimney faces the street.
WeatherSpark shows Seattle's winds swinging round to the north for a short summer stretch, July 3 to September 20; the rest of the year they come mostly from the south, driving rain at whichever chimney face looks south or upslope. Seattle's emergency managers add that damage to structures begins at around 32 miles an hour, and recall that the 2006 storm left nearly half of City Light's customers without power.
For a house on the slope above the lake, that means two things. We book flashing work in the drier northerly stretch whenever the leak allows it, so new sealant cures before the south wind returns. And after a big storm we check the flashing on the south and west sides first, because that is where lifted metal lets rain in.
Every chimney flashing repair we do in Mount Baker includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe 2021 Seattle Residential Code asks for a cricket, a small peaked saddle on the uphill side, wherever a chimney runs wider than 30 inches along the ridge direction without meeting the ridge itself. The joint between that cricket and the chimney is to be flashed and counterflashed exactly like the rest of the roof intersection (section R1003.20). An older house that never had one tends to collect water and debris in a pocket behind the stack, and that pocket is a classic leak point. Where the rule applies, we include the cricket in the quote.
Attic first, roof second; if neither shows the entry point, a hose wets one side of the stack at a time while someone watches below.
Roofing is lifted around the chimney, and old metal and sealant come off down to clean brick and decking.
Underlayment, step flashing, counterflashing and, where required, a cricket go back in the right order.
We wet the area again, check the attic, and send photos of every side.

Moss itself does not destroy roofing, Oregon State University Extension explains, but its cushion pries asphalt tabs upward and rain then finds the gap. Around a chimney, that is exactly where step flashing sits. On a shaded Mount Baker lot, a ring of moss at the base of the stack often marks the leak before any stain appears inside.
OSU also advises cleaning the roof before any moss treatment and notes the work is not for everyone. We remove the moss from the area we are flashing and leave the wider roof to you or your roofer. WeatherSpark gives Seattle's clear season as June 13 to October 8, which is also the best time to let a cleaned roof dry before new metal goes on.
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.
Sometimes, for a small gap on metal that is otherwise sound, and we quote it that way. Caulk alone over failed or rusted flashing usually lasts one winter.
Only the shingles or roofing we lift around the chimney. Should the rest of the roof look worn out, we tell you and leave that decision to you and your roofer.
Then the flashing quote does not go ahead. A chimney inspection, at $99 plus tax, can find whether water is entering through the crown, the brick or the flue, with that charge credited to the quote you approve.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
