High Point, King County
Waterproofing a chimney in High Point costs $320 to $795, with the spread set by the height of the stack and the square footage of masonry to treat. The product is a breathable water repellent: it stops rain soaking in from outside while letting vapor from inside the brick escape. It is meant for brick, block or stone. A sided chase relies on paint, caulk and a metal chase cover instead, so we look before we sell.

Two kinds of High Point owners ask for this. The first live in the older houses bordering the redevelopment, where a brick stack has absorbed many winters of rain. The second own a recent home whose fireplace wall is faced in brick or manufactured stone; a veneer soaks up water just as full-depth brick does, and the sheathing behind it is less forgiving. In both cases the repellent goes on only after cracks and open joints are closed, because a sealer bridges pores, not gaps.
HistoryLink dates the beginning of High Point's reconstruction to 2004, and the neighborhood site reports buildings completed as late as 2020. Masonry of that age has not had time to become porous through wear; if it takes on water, the usual culprit is a detail at the top or at the flashing.
The surrounding ZIP code area tells another story. Census estimates there give the 1940s alone 15.7 percent of all housing units. Brick laid in that decade has been wetted and dried thousands of times, and it drinks water readily. For those stacks a repellent is ordinary maintenance, applied after the joints have been made good.
Every chimney waterproofing we do in High Point includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowTiming matters more than product. November is the wettest month in WeatherSpark's Seattle profile, with roughly 7.5 inches arriving on some 17 separate days, whereas July brings less than one inch. Repellent needs a dry surface and a dry day or two afterward, which makes late spring through early fall the working window. A booking made in winter is usually an inspection now and an application once the masonry has dried out.
Solid brick, veneer or siding: the material decides whether a repellent is even the right answer.
Open joints, a split crown or loose flashing are flagged and quoted, because repellent will not stop water entering through a hole.
We clean the masonry, let it dry, then spray it from the bottom up until it stops absorbing.
You receive the product name and the application date so the next coat can be planned.
The Seattle Housing Authority built a natural drainage system here: more than four miles of grassy and planted swales to handle stormwater. It is a careful answer to rain once it reaches the ground. Nothing equivalent protects a masonry surface standing above the roofline.
Planting brings shade, and shade brings moss. Oregon State University Extension warns against one common moss killer in a specific case: zinc sulfate should stay off a roof that has copper flashing, gutters or downspouts, because zinc attacks copper. We clean masonry before sealing with products chosen for the metals around it, and we never seal over living growth.

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.
Count on a fresh coat somewhere between the third and the fifth year under Seattle rain. A stack in full shade, which dries slowly, sits at the short end of that range.
No, and you should be wary of anyone who offers to. Siding needs sound paint and caulk, and the leak on a chase is nearly always at the metal cover on top.
Always. The $99 plus tax we charge to inspect a chimney is not an extra in the end: once the waterproofing quote is accepted, that same $99 is removed from what you owe.
