Snoqualmie, King County
Waterproofing a chimney in Snoqualmie costs $320 to $795, and surface area sets the figure: a short stack on a single-story roof is the low figure, a tall or wide chimney with difficult access the high one. We use a water repellent that breathes. It soaks into brick and mortar and makes rain bead and run off, yet vapor from inside the wall can still get out.

The case for sealing masonry is stronger here than anywhere else we work. In WeatherSpark's model, November brings about 8.0 inches of rain to Renton and 9.8 to Snoqualmie, and the wetter season ends on May 2 at the lake but not until May 31 in the foothills. Four extra weeks of rain on bare brick, every year, add up. A repellent does not replace a sound crown or tight flashing. It protects the vertical faces those parts cannot cover.
A water repellent has two requirements: masonry that is dry on application day and fair weather for the cure. Winter rarely offers either. In western Washington's wettest months, the Western Regional Climate Center finds, it rains or snows on 20 to 25 days and sometimes more, while a winter month offers no more than four to eight days without full overcast.
The opening comes in summer. WeatherSpark places Snoqualmie's clearer part of the year from about June 21 to about October 4, some 3.5 months. That is when we schedule waterproofing in town. A stack treated in August meets the October rains already protected, and the repellent has had weeks to bond.
Every chimney waterproofing we do in Snoqualmie includes:

Book nowShade slows drying. Roughly 77 percent of the ground in a two-mile circle around town is under trees, WeatherSpark's summary shows, and Oregon State University Extension describes roof moss as inevitable in the moist Northwest, adding that moss needs shade and keeps the surface under it wet. A chimney face that stays green and damp is a face that never fully dries between storms. We clean growth off before treating, and we do not pressure-wash brick, which can damage the surface.
Water is applied to a few spots to see how fast the masonry drinks it, which tells us how much product the wall will take.
Open joints and crown cracks are fixed beforehand, since a repellent cannot bridge a gap.
Growth and dirt come off, and the stack is left to dry so the treatment can penetrate.
Working upward from the lowest course, we flood the masonry until it takes no more, then photograph the job.

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.
We advise planning for a new application every three to five years. Exposure decides which end of that span applies: a tall stack facing the weather wears faster than a sheltered one.
A film-forming coating traps moisture inside the brick. When that trapped water freezes it pushes the face off. A breathable repellent keeps liquid water out and lets vapor leave.
The stack is inspected first for $99 plus tax, to confirm it is fit to treat. Approve the waterproofing quote and the fee is credited to it.
