Othello, King County
Waterproofing a brick chimney in Othello costs $285 to $795. A compact single-flue stack, already sound, needs one visit and sits near the bottom. A tall or wide chimney, several faces to mask around siding, or a crown that also needs a coat moves the job up. We use a vapor-permeable repellent, which turns away rain on the surface yet lets the brick dry out from inside.

Before anything is sprayed, we check that there is masonry to protect. About 28 percent of the housing in the 98118 ZIP area has gone up since 2000, Census figures show, a period that covers both NewHolly's completion in 2005 and the apartment buildings near Othello station. Some of those homes have no brick chimney at all. Others nearby date from before 1940 or from the 1950s and 1960s. A repellent belongs on porous brick and mortar, not on metal chase siding or a factory-built pipe, so the first answer you may get from us is that your house does not need this service.
Utility gas is the main heat for about 40.3 percent of the occupied homes the Census counts in 98118. In a house from the 1950s or 1960s, a gas furnace or water heater may still vent into a masonry chimney, and gas combustion produces a lot of water vapor. When that vapor cools in a wide, cold flue, it condenses on the inside of the brick.
That is why a chimney here can be wet from two sides at once: rain soaking in from outside through Seattle's long, cloudy season, and condensate soaking in from inside. A repellent handles the first. The second is a venting question, usually solved with a liner sized to the appliance. When we waterproof a mid-century stack, we also tell you what is venting through it, since sealing the outer faces of a stack that is wetted from inside is money spent on half the problem.
Every chimney waterproofing we do in Othello includes:

Book nowWeatherSpark dates Seattle's rainy half-year from about October 10 into the last days of April. In January, about 71 percent of the time the sky is overcast or mostly cloudy. Brick takes in that water through the faces and through any hairline joint, and it gets few sunny afternoons to give it back. Wet masonry stains, grows moss and loses mortar faster. A repellent cuts the amount that gets in; it does not close cracks, so open joints are repaired before the coat, never painted over.
Up on the roof, we decide whether a repellent can do anything for this chimney.
Moss and grime are removed, and the job waits for a dry window so the brick can take the product.
Open joints and crown cracks are filled, because a coating cannot bridge them.
The repellent is flooded onto each face from the top down, with surrounding surfaces masked.
Photos show each treated face, and we note the date so you know when to recheck.

$285 to $795 for a sound brick chimney. Size, number of faces and any crown treatment set the figure. Joint repairs, if needed first, are quoted separately.
Mad Hatter Chimney Sweep, among other Seattle companies, publishes $200 to $500 for a water-repellent application. That is their figure, not our quote.
Only if the chimney is masonry. Many newer homes have a framed chase clad in siding or metal, which needs its own checks, not a brick repellent.
Years, not decades. The Seattle company quoted above says its coat lasts five to ten years. Watch the stack after a light shower: once the brick darkens at once instead of beading, a recoat is due.
