Greenwood, King County
Waterproofing a chimney in Greenwood falls between $320 and $795. Size is the first factor, since product and time both scale with the brick to be covered. Condition is the second: a stack with moss or heavy staining has to be cleaned and dried before treatment, which can mean a second trip. A chimney that rises from the eave of a low roof is cheaper to treat than one reached only by a long ladder set on uneven ground.

Water is part of Greenwood's identity. Under the middle of the neighborhood there is peat, and HistoryLink traces its origins to a bog beside a cemetery laid out in 1891. Drainage lagged behind the houses for generations; the same essay has the storm drains unimproved as late as the 1970s. A chimney does not stand in the bog, but it lives in the same air and under the same sky, and old brick takes up water readily. The aim of a repellent is narrow and useful: stop liquid water from soaking into the brick face while leaving the pores open.
Every chimney waterproofing we do in Greenwood includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowTwo mistakes cause most of the failed treatments we are called to redo. One is the wrong product. Paint, clear acrylic sealers and anything else that forms a skin hold moisture inside the masonry, and the brick face eventually pops off behind the film. The other is the wrong order. Repellent does not bridge an open joint or a cracked crown, so those are repaired first and left to cure. When we find either problem on a Greenwood chimney we explain it with photos and quote the repair separately, so you are never paying to waterproof a leak.
A peat deposit lies beneath Greenwood's center, Wikipedia records, and in 2008 Seattle made peat bog an Environmentally Critical Area. Storm drains, by HistoryLink's account, were unfinished business in the 1970s still. For rainfall we have only regional and citywide figures: the Western Regional Climate Center's 32 to 35 inches a year for the lowlands as far north as Seattle, near the edge of the Olympic Mountains' rain shadow.
Those totals are moderate. What wears on masonry here is duration: the brick is wetted again before it has dried from the last rain. That is the argument for a vapor-permeable product in Greenwood. Moisture already in the chimney, whether it came through the crown, up from a damp base or from indoor air, must be able to leave through the brick face. A breathable repellent allows that and still turns away the next shower. How long such a treatment holds is, on one Seattle company's website, 5 to 10 years, and the same page proposes renewing at 5 to 7.
We confirm the stack is sound enough to treat and identify any previous coating.
Open joints and crown cracks are repaired under a separate quote and allowed to cure.
Cleaning comes first, then a wait for dry weather so the brick is not holding water.
The repellent goes on wet-on-wet from the base of the exposed stack to the top.

$320 to $795. Stack size, the cleaning required beforehand and the way up to it account for the difference.
A Seattle chimney company's website reckons a masonry repellent good for 5 to 10 years, and on Seattle-area chimneys advises a fresh coat at 5 to 7. A simple splash test each fall shows whether water still beads.
Rarely well. The brick must be dry when treated and stay dry for a while afterward. WeatherSpark's Seattle data shows July as the driest month, at 0.7 inch of rain, so summer bookings are the reliable ones.
It pays for the inspection that precedes any treatment: $99 plus tax. Approve the waterproofing quote and that sum is taken off what you owe for the work.
