Carnation, King County
Waterproofing a Carnation chimney runs $285 to $790. Stack height, the number of faces to treat and how much cleaning the brick needs first explain the gap between those two figures. The product is a breathable water repellent, not a paint or a film, and it goes on only after the masonry has been checked and any open joints closed.

Carnation is the wettest of our four towns and the one with the oldest brick, which is the combination waterproofing was invented for. Roughly 30% of its housing predates 1980 by Census estimates, half of that share from before 1960. Old brick is more porous than new, and a stack that has absorbed water for sixty winters will keep absorbing it until something changes at the surface.
Above Carnation, in the Cascade foothills, a weather station at the Tolt South Fork reservoir recorded 95.20 inches of precipitation in an average year between 1962 and 2016, plus 53.4 inches of snowfall. The Tolt River brings that runoff down to town, where the city keeps watch on its gauge 5.5 miles to the northeast.
The valley floor is drier than the foothills, but it sits at the receiving end. Ground stays saturated, mornings stay humid, and brick close to grade dries slowly. On a chimney that starts at ground level we treat the full height, not only the part above the roof, and we check that soil and mulch are not piled against the lowest courses.
Every chimney waterproofing we do in Carnation includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowBrick behaves like a hard sponge. It takes in rain, holds it, and releases it slowly, and a chimney stands above the roofline with all four sides exposed. Repellent changes the first step only: water beads and runs off, while vapor from inside the masonry can still escape. That second point is why we refuse to use sealers that form a skin. A skin traps moisture behind it, and the brick face comes off with the first frosts. Treatment is also not a repair. Cracked crowns, open joints and loose flashing are fixed first, or the repellent simply seals water in.
Repellent needs dry masonry going in and dry weather while it cures. In Carnation, WeatherSpark locates the clearer part of the year between about June 21 and October 6, roughly 3.5 months, with July bringing only about an inch of rain.
Outside that window the odds turn quickly. By WRCC's regional account, December and January commonly log precipitation on 20 to 25 days apiece, and muggy summer heat is absent here all year, so the moisture that matters is cool-season rain and cloud. We book treatments from late June onward and stop when the fall rain sets in.
A water test with a hose, face by face, tells us whether the brick itself is taking water or whether the crown or flashing is to blame.
Growth and dirt come off with brushes and a low-pressure rinse. The stack must then dry out, which is why this job belongs to summer.
Repellent is sprayed from a low-pressure tank until the brick stops absorbing it. Mortar joints get particular attention.
After curing, a splash of water should bead on every face. We photograph that test for your records.
