Medina, King County
Medina chimney waterproofing is priced at $285–$795, set mostly by how tall the chimney is and how many brick faces stand in the weather. We use a breathable repellent, meaning water is kept out but moisture already in the brick can still escape. It only goes on masonry that is sound, so we check first.

Medina sits on Lake Washington with nothing but single-family homes, many of them large houses with tall, exposed chimneys. A repellent is one of the least visible jobs we do on those stacks, which is part of its appeal: done properly, the brick looks the same afterward and simply stops soaking up rain.
Washington OFM lists all of Medina's housing units as single-unit homes, and the city is known for large houses on big lots. A chimney that serves more than one flue is often wider and taller, with more brick exposed to rain on more faces.
We treat the whole chimney, not just the side you can see from the garden. CSIA's Level 2 standard also includes every flue in the chimney, so before we seal we confirm each flue is capped: a repellent on the outside does nothing for rain falling straight into an open flue.
Medina hugs the Lake Washington shore, and the city reports that water makes up about 3.39 of its 4.83 square miles. The lake is fresh water, so the enemy is plain rain, pushed sideways into the brick by wind rather than falling straight down.
The Western Regional Climate Center notes that this side of the state takes its heaviest gusts mostly on a south or southwest heading, and mostly once autumn turns to winter. Those faces absorb the most water, and they are where a missing or worn-out repellent shows first.
Every chimney waterproofing we do in Medina includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe mistakes we undo are usually well meant. Brick sealed with a glossy coating that traps moisture and makes faces flake. Repellent sprayed over open joints that should have been repointed first. A treatment applied years ago and never renewed. Each one leaves the owner thinking the chimney is protected when it is not.
We look at every face and joint; anything cracked or open is repaired before sealing, or the repellent would lock damage in.
The brick is brushed and cleaned so the repellent reaches the masonry rather than surface grime.
A breathable repellent is applied in dry weather, saturating each face evenly.
We photograph the finished stack and note when it is worth reviewing again.

Against water damage, CSIA points to four inexpensive defenses: cap the chimney, keep the crown in shape, keep the flashing tight, and treat the masonry with a repellent. Waterproofing is only the last of those, and it works best when the other three are in order.
Brick here has a lot to repel. Rain is frequently recorded on 20 or more days a month in December and January, and a crown built without its roughly two-inch overhang sends that water down the face. We check the crown before sealing so the repellent is not left doing the crown's job.
Medina is an exclusive lakefront enclave with some of the region's most valuable estates, on Lake Washington, with large waterfront and estate homes.

$285–$795. Expect the bottom of that range for a short chimney showing little brick, and the top for a tall stack with several faces on show.
The brick needs to be dry enough to take the product, so we schedule around the weather. Late summer and early fall are the easiest windows.
