Sammamish, King County
Brick chimneys in Sammamish are mostly not old. The census finds just 117 homes here built before 1940, about half a percent of the city, and a median construction year of 1994. What wears them is not age but exposure: a crown poured flat thirty years ago, mortar joints facing the south wind, a stack shaded by trees and never fully dry. Crown and repointing work starts at $475 and is quoted from photographs taken on your roof.

Washington's 2021 residential code spells out what the top of a masonry chimney should be: the cap may be stone, metal or concrete; it has to slope so rain drains away, carry a drip edge, and leave a caulked bond break wherever a flue liner comes through. The usual failure is the opposite: a thin mortar wash with no overhang and no joint at the tile. It cracks, water enters at the liner, and the brick below starts to show it. Rebuilding a crown to the code's description is often the single repair that stops the rest.
In the damp Pacific Northwest, roof moss is a certainty, in the view of Oregon State's extension service; its lasting remedy is to change the setting by cutting back nearby trees until sunlight reaches the surface. On the Sammamish plateau, where the city's hazard annex finds trees or woody shrubs covering 48% of the land, plenty of chimneys stand in permanent shade.
Moss and needle litter on a crown or on the stepped shoulders of a chimney hold water against the mortar. We remove growth by hand before repointing, never with a pressure washer on soft joints, and we tell you which overhanging branches are keeping the masonry wet.
Every masonry repair (crown / repointing) we do in Sammamish includes:

WeatherSpark dates it from about November 13 to March 1 in Sammamish, with December lows averaging 37°F, and the Western Regional Climate Center puts average January minimums across the Puget Sound lowlands between 28°F and 32°F. Saturated mortar that freezes overnight loses a little of its face each time. Joints recede, then brick faces flake. Caught at the joint stage it is a repointing job. Left until bricks spall, it becomes a partial rebuild.
Every face of the stack and the whole crown are photographed so you can see which joints and bricks are in the scope.
Loose crown material and soft joints are removed with dust control at the roof and the gutters protected.
The crown is formed and poured, joints are packed and tooled, and replacement bricks are set to the original bond.
Fresh work is protected from rain while it cures. We return photos of the finished crown and joints.
Sammamish's hazard annex notes that the city's wildfire risk, low in the past, is rising as drought stresses the trees, and it recalls the 1939 Beaver Lake Fire that began on the plateau. Sound masonry is part of how a chimney contains heat: open joints and a broken crown are gaps in the one structure built to carry fire through the roof.
Dry months are also when this work is best done. The Puget Sound Clean Air Agency points out that wildfires typically occur in the warmer, drier summer months. If smoke is heavy on a scheduled day, we reschedule roof work instead of running grinders in bad air.

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.
From $475. A crown on a single-flue chimney is near the starting figure. Repointing is priced by the area of wall involved, and replacing spalled brick adds to it. You get one written number before we begin.
Small repairs can, under cover. For a full crown or a large repointing job we aim for the drier stretch, which WeatherSpark places between mid-June and early October, because mortar and crown mix need to cure without being rained on or frozen.
From the roof. Our inspection, $99 plus tax, answers that question, and once you approve the masonry quote the $99 counts toward it.
