Wallingford, King County
In Wallingford our waterproofing fee for one chimney is $320 at the low end and $795 at the high end. Area decides most of it. An interior chimney shows only a few feet of brick above the shingles and takes little product; an exterior one, exposed from the ground to the cap on the side of a two-story box house, has four or five times the surface. Brick texture counts too, since rough, open-faced brick absorbs more repellent per square foot than smooth pressed brick. Preparation is included in the price. Repairs that must come first are not, and are quoted apart.

Nearly half of Wallingford's housing structures, 45.9 percent in the figure Wikipedia's article carries, were built before 1939. Its early landmarks date from the same years: the Valencia Apartments of 1909, which a city survey of business districts singles out among early Wallingford buildings, and the Latona and Interlake school buildings, designated in 1981. Chimney brick of that generation may never have been treated with anything, and that helps. A modern penetrating repellent bonds inside clean, uncoated pores; it cannot do so on brick that a past owner painted or sealed with a film.
The two long weather records for this side of Seattle disagree by about four inches. The University of Washington station, read from 1909 to 1983, averaged 34.11 inches of precipitation a year. Portage Bay's, kept near Lake Union for the 26 years to 1998, averaged 37.92. WRCC's narrative for the state brackets both: 32 to 35 inches along the lowlands up to Seattle, which it places close to where the rain shadow cast by the Olympics runs out.
Whichever figure fits a given Wallingford block, the pattern is the same: a wet season WeatherSpark dates from October 10 to April 30, when the odds that a particular day turns out wet exceed 33 percent. Untreated brick takes on water in each of those spells and gives it back slowly. A repellent does not make the chimney dry; it makes each wetting shallower, so the brick is back to dry before the next front instead of staying saturated from November to March.
Every chimney waterproofing we do in Wallingford includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowAsk three questions before paying anyone to waterproof a chimney. Is water entering through the brick at all, or by way of the cap, the crown, the roof flashing? A repellent fixes only the first. Are the joints sound? Product sprayed over hollow joints is wasted. And what was put on the chimney before? A previous film coating has to be identified, because a breathable repellent applied over it will sit on the surface and peel. We answer all three on the roof, with a hose and a moisture meter when the leak is not obvious, and we decline the job when the answer is no.
Top, joints and roof joint are checked so the repellent is not blamed for a leak it could never stop.
The masonry is cleaned, left to dry, and everything below it is masked.
Low-pressure spray, face by face, with a second pass before the first has dried.
Once cured, water is sprayed on and filmed beading; you keep the clip.

One Seattle chimney company publishes a service life of 5 to 10 years for water repellent on masonry and recommends a new application every 5 to 7 years locally. Exposure matters: a face that takes the southwest weather wears out first.
Not usefully. Paint blocks the pores the repellent needs. We tell you that before any money changes hands.
The assessment. It is an inspection, and each chimney is $99 plus tax. Once you approve waterproofing on that basis, the $99 counts as part payment.
