Rainier Valley, King County
Waterproofing a chimney in the Rainier Valley costs $285 to $795. A short single-flue stack with sound joints is near the low end; a tall stack, several faces exposed above a two-story roof, or masonry that needs cleaning first moves it up. What we apply sheds liquid water but stays open to vapor, so damp already trapped in the brick can still dry outward.

HistoryLink describes the Rainier Valley not as a river valley but as low land between two ridges, running some seven miles southeast from the center of Seattle down to the lake. Rain does not skip the low ground. Lowland Puget Sound gets 32 to 35 inches of precipitation yearly; winter months bring 4 to 8 days with any real sun and summer months 15 to 20, by the Western Regional Climate Center's count. Masonry here gets soaked repeatedly and has few dry days in between to give the water back.
In the 98118 ZIP area, the Census Bureau's table B25024 finds 59.2 percent of the housing stock in detached single-family houses; the citywide figure is 36.8 percent. In HistoryLink's telling, a postwar construction boom in the valley did much to give that ZIP area its present form.
A chimney on a detached house is open to weather on every face above the roof, not sheltered by a neighbor's wall. On a postwar stack that has since taken an insert, the joint where a stainless liner leaves the crown also needs sealing before any repellent goes on, or water simply runs down beside the liner. We treat that joint with a sealant made for metal-to-masonry gaps and keep repellent off the liner itself.
Every chimney waterproofing we do in Rainier Valley includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowA repellent is the last step, not the first. Applied over open joints or a cracked crown it does nothing for the water entering through the gap, and a film-forming sealer that traps vapor can make brick spall faster. So we start by looking at the joints, crown and flashing, fix what is open, let repairs cure, and only then apply. Expect to reapply after three to five years here; the invoice records the date so the next coat is easy to plan.
Joints, crown and flashing are examined; anything open is repaired first and left to cure.
Biological growth and salt deposits are removed so the repellent can soak into bare masonry.
Application waits for masonry that has dried out over a few days and a forecast with no rain until evening.
Repellent goes on top to bottom until the masonry stops absorbing, then the crown is treated.

Four steps, each one on paper — so you always know what happens next.
Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
Only when the brick has had a few dry days and none are forecast wet for the next few hours. Late spring through early fall is easier to schedule.
Not if the leak comes from flashing, a cracked crown or a missing cap. We find the source first; repellent is for water soaking through the brick itself.
Start with an inspection at $99 plus tax; if you then sign for the work it points to, that charge is netted out of your quote.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
