Georgetown, King County
Waterproofing a Georgetown chimney runs $285 to $795. A short stack on a one-story cottage, cleaned and treated in a single visit, is the low figure; a taller chimney with more faces to cover, or one that needs moss and old coatings removed first, is the high one. We use a breathable, vapor-permeable repellent, so water stays out of the brick while moisture already inside can still escape.

Sealing brick is a dry-weather job, and Georgetown's dry weather is short. WeatherSpark's model of the Boeing Field station, the closest long record to the neighborhood, finds skies opening up on June 14 and staying fair until October 8, a run of roughly 3.8 months. Outside that window the masonry is rarely dry enough for a repellent to soak in properly. We book waterproofing for summer and early fall, and we would rather move an appointment than coat damp brick.
Every chimney waterproofing we do in Georgetown includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowTwo details shape the work here. One is that the city's survey describes most historic homes here as small houses on narrow, deep lots, so overspray control and drop cloths on the adjoining roof and siding are part of the setup. The other is that a repellent only protects masonry that is sound: eroded mortar, a split crown or flashing pulling loose gets fixed first, or the water simply goes around the treated surface. cloud hangs over the airfield for nearly three-quarters of January, so brick that takes on water in December can stay wet for weeks.
We look at joints, crown and flashing. If repair is needed, it is quoted and done before any sealer, because a repellent cannot bridge a crack.
Faces are brushed and washed free of moss and grime, then left to dry.
On a narrow lot the neighbor's wall may be a few feet away, so adjacent surfaces are covered.
Working downward from the crown, we flood each exposed face with repellent until the brick stops drinking it in.
You get photos and the product used, so the next treatment can match it.

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.
Because a repellent needs dry brick to penetrate. In wet months it sits on the surface and does little. We fix the leak source in winter if needed, and treat in the dry season.
Not a breathable one. Film-forming paints and glossy sealers can, which is why we strip those where they are failing and use a vapor-permeable product instead.
Usually several years, depending on exposure. South-facing faces, which take the most wind-driven rain here, wear first.
Yes, $99 plus tax. If the visit ends in a waterproofing or repair quote that you accept, the $99 is subtracted from that work.
