Phinney Ridge, King County
Budget $320 to $795 to have a Phinney Ridge chimney treated against water. Square footage decides most of it: a short stack that barely clears the roof takes one pass and little product, while a tall exterior chimney exposed on three sides drinks far more. Brick that needs washing first, or a roof that calls for extra safety rigging, accounts for the remainder.

The ridge's east slope was cleared late and built on fast. HistoryLink recounts that the streetcar loop around Green Lake was completed in 1902, opening that slope to builders, and that loggers took off its fir and cedar the following year for Parker's sawmill. By 1903 about 2,000 people were living on the eastern slope. Brick laid in the building wave that came next has been absorbing rain for well over a hundred winters. Old brick of that kind is porous by nature, and it has usually lost the hard outer skin it left the kiln with.
Every chimney waterproofing we do in Phinney Ridge includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWaterproofing is the last step, never the first. Repellent sprayed onto open joints or a cracked crown seals nothing; water still gets in through the gap and then has a harder time getting out. So we look at the masonry before quoting, and if joints have to be redone the repellent waits until the new mortar has cured. Product choice matters as much: a film-forming sealer or paint traps moisture inside the brick, while a breathable siloxane-type repellent lets vapor escape and keeps liquid water from soaking in.
Seattle's dry window is short. According to WeatherSpark, the clearer part of the year lasts only about 3.8 months, starting in mid-June and ending around October 8; July is the driest month with 0.7 inch of rain, and January the cloudiest, when skies are mostly cloudy or fully overcast 71% of the time. A repellent needs dry brick going on and dry hours afterward, so nearly all of this work belongs in that window.
The rest of the year is the test. One Seattle chimney company states that a masonry water repellent holds for 5 to 10 years and recommends reapplying every 5 to 7. On the ridge we lean toward the short end of that range for the faces that meet the weather. The reason is exposure: high ground gets more wind, and wind is what turns ordinary rain into water forced against a wall.
A little water on the brick shows how quickly it soaks in and whether an earlier treatment still works.
Any joint or crown defect is quoted and fixed before treatment, or the treatment is postponed.
The stack is washed where needed and left to dry. The product must go on dry brick.
With the surroundings covered, a gentle spray feeds the brick until it stops absorbing.
Product and date go on file, which gives the next treatment a known starting point.

$320 to $795. The surface to cover and the preparation the brick needs decide where your chimney falls.
One Seattle chimney company says on its website that 5 to 10 years is the life of a masonry repellent, and that on chimneys around Seattle a fresh application is due after 5 to 7. Exposure shortens that, so a windward face is worth testing sooner.
No. A penetrating repellent leaves no gloss or film. Rain beads on the surface where it used to soak in.
We need to see the masonry before treating it, and that visit is the inspection, billed at $99 plus tax. Once you say yes to the waterproofing quote, the fee is counted as part of the payment.
