Arbor Heights, King County
Waterproofing a chimney in Arbor Heights runs $320 to $795. The work is a vapor-permeable water repellent soaked into the brick and mortar of the stack, so rain beads off the outside while moisture inside the masonry can still escape. Size sets the price: a short single-flue stack sits near $320, a tall, wide one with a large crown nears $795. We only treat sound masonry, so any open joints or cracked crown are dealt with first and quoted separately.

A chimney here rarely gets a chance to dry. In January, by WeatherSpark's Seattle figures, overcast or mostly cloudy weather fills some 71 percent of hours; the same profile counts November as the wettest month, with roughly 16.7 wet days. Brick that is rained on twice a week and seldom sees sun stays saturated through the season. A repellent does not stop the rain, it stops the brick from drinking it, which is what keeps the masonry from cycling between soaked and frozen.
Every chimney waterproofing we do in Arbor Heights includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe usual mistake we undo is a glossy sealer brushed on years ago. Such film seals dampness inside the wall, so eventually the brick surface blisters, then peels. The other common case is a crown that was never sealed at all, letting water straight into the core of the stack whatever is applied to the sides. A proper job treats the crown, the brick and the joints as one system.
A repellent cannot bridge a crack. We look for open joints and a damaged crown first and quote those repairs on their own.
Moss, dirt and loose grit are brushed off so the product soaks into clean pores instead of sitting on grime.
We spray on a day forecast to stay dry long enough for the repellent to penetrate, flooding the surface until it stops absorbing.
The top gets a flexible coating that bridges hairline cracks and moves with the masonry as temperatures change.
Census estimates say 49.6 percent of dwellings in Arbor Heights' ZIP area date from 1940 to 1969, and 37.1 percent from 1950 to 1969 alone; only 9.5 percent predate 1940. If your chimney is masonry and came with a house of that era, its brick and mortar have been weathering for sixty years or more.
Weathering opens the surface. Mortar loses its fine particles, brick faces erode, and the masonry absorbs more water each decade. Seattle's wetter season, which WeatherSpark sets at about six and a half months beginning October 10, is a long time for a porous stack to stay wet. That is why a repellent pays off more on a stack of this age than on a new one, provided the joints have been repaired first.

A breathable repellent dries clear and leaves the brick its natural color. Glossy sealers are what change the look, and we do not use them.
Several years, depending on exposure. The face that takes the southerly rain usually wears first, and we can retreat that side alone.
Then waterproofing may not be the answer, or not the whole answer. An inspection for $99 plus tax tells us where the water enters, and when you approve the fix we quote, those $99 are deducted.
