Kenmore, King County
Chimney waterproofing in Kenmore costs $285 to $795. A short stack with one flue prices near the bottom; a tall chimney with several exposed faces above the roofline prices near the top. The treatment is a vapor-permeable water repellent: liquid water beads off the face, yet vapor already inside the brick is free to escape.

Kenmore's brick chimneys spend most of the year damp. From October to spring, rain arrives on more days than not, and a stack standing above the roofline catches it on every face. Brick and mortar are porous; left bare, they soak up water all season and dry out only in summer.
The King County survey of Kenmore describes Uplake Terrace, platted in 1953 on a hillside above the lake, as mostly Ranch and Split Level houses of the 1950s and early 1960s. Citywide, the Census dates 2,741 homes to the two decades from 1960 through 1979.
Brick of that era has already absorbed decades of rain. Where the stack has been repointed and the crown repaired, a repellent is a sensible last step to protect that investment.
Every chimney waterproofing we do in Kenmore includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWater held in the masonry is what drives most chimney decay here: spalling faces, crumbling joints, white mineral bloom, rusted steel at the damper and stains on the ceiling beside the chimney. Waterproofing slows that cycle down, but only on masonry that is already sound. On a cracked crown or open joints, it is money spent in the wrong order.
WeatherSpark counts about 17.1 wet days in an average Kenmore November, the wettest month, with December skies mostly or fully clouded over for roughly 72 percent of the month. In the state's inland lowland valleys, the regional climate center measures January humidity near 87 percent at 4 a.m., easing only to about 78 percent by 4 p.m.
Rain on most days and little sun or dry air to evaporate it: that is why unprotected brick here stays wet so long, and why a repellent earns its place on a sound chimney.
Cracks and open joints are repaired first; treating over them would seal water in rather than out.
We clear the surface and wait for a dry window, since the repellent has to go onto dry brick to soak in.
The product is applied until each face is saturated, from the crown down to the flashing.
Water sprayed on the finished brick should bead and run off; we photograph that for your records.

The 2021 Washington State Residential Code sets how a chimney meets the roof and the weather: 3 feet or more clear of the roof where it exits, 2 feet above anything within 10 feet, and a cricket, flashed and counterflashed, on a stack wider than 30 inches that does not reach the ridge.
A repellent does not replace any of that. If the height, the crown or the cricket is wrong, water will find its way in regardless, so we flag those issues before quoting a treatment. Since March 15, 2024, King County has applied the 2021 codes to complete applications.
Kenmore is a city on the northernmost shore of Lake Washington, where the Sammamish River meets the lake, on Lake Washington, with Ranch and Split Level houses from the 1950s and early 1960s beside newer homes, for a median build year of 1985. We work every part of it — Uplake Terrace included.

$285 to $795. Where you fall depends on the stack's height, how many sides stand clear of the roof, and the prep work the surface needs.
Several years, depending on the product and how exposed the chimney is. The south and southwest faces usually weather first, and we note when to check again.
Only in a real dry spell, because the brick must be dry for the repellent to penetrate. Late spring through early fall is the easier window in Kenmore.
