Rainier Beach, King County
Waterproofing a chimney in Rainier Beach costs $285 to $795. A short stack of sound brick that we can reach from a low roof sits near $285; a tall chimney, one with several flues, or one that needs staging on a steep pitch moves toward $795. The product is a breathable siloxane-type repellent: water beads off the face while moisture inside the brick can still escape.

Timing is most of this job. In WeatherSpark's long-term record for Seattle, the wet season runs October 10 to April 30, and November alone brings about 7.5 inches over close to 17 rainy days. July, at the other extreme, gets about 0.7 inches. A repellent wants dry masonry when it goes on and a rainless spell after, so this work goes on our calendar between July and September, and we tell owners who call in December that the best we can do then is inspect and plan.
For roughly nine and a half months a year, WeatherSpark reports, Seattle's wind blows mostly out of the south, the exception being a summer stretch, July 3 to September 20, when it swings round to the north. The Western Regional Climate Center describes the same pattern for the whole Puget Sound lowland, where the wet-season wind comes from the south or southwest. Rain arriving on those winds hits the south and southwest faces of a chimney head-on, and in a neighborhood that sits at the southern tip of Seattle's lakeshore those faces are the ones we expect to find darkest.
That is where we put the extra coat. It is also where we press a moisture meter before starting, because a south face can still be wet two days after the rest of the stack has dried. No source we read measures whether the shore itself changes how hard the rain is driven, and we do not need one: we read the brick in front of us.
Every chimney waterproofing we do in Rainier Beach includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowA repellent is not a patch. Put on brick whose joints are open or whose crown has split, it leaves water free to enter through the gaps and then slows its escape through the face. Seattle's chimney rule makes the same point from another angle: unreinforced masonry kept in service during a repair must be looked over for decay and tuckpointed wherever joints have failed. So every waterproofing quote starts with the joints and the crown. If they need work, that is priced on its own line and done first, and the sealer goes on only once the mortar has cured.
We look at mortar, crown and brick first. Waterproofing is only quoted on its own if the masonry is sound.
The stack is brushed down and left to dry. We do not seal over a surface still holding last week's storm.
Two flood coats, worked from the roofline upward, with a moisture meter reading taken first.
Once cured, a spray of water should bead and run off. We photograph the result and note the date for the next application.

A repellent coat is listed at $200 to $500 by Mad Hatter Chimney Sweep, the one name among other Seattle companies we found posting a figure for it (seen October 4, 2026). Not our quote. Repairs to the masonry are extra everywhere.
It varies with exposure, usually several years. The face exposed to wind-driven rain wears first, so that is the one we test at each inspection.
A breathable repellent dries clear. Paint-like coatings that trap moisture are a different product, and we do not use them on brick chimneys.
Yes. Book an inspection first: $99 plus tax for one chimney, and if you then approve our quote, the bill drops by those $99.
