Local Conditions

Chimney problems we see in Sammamish

The plateau sits above Lake Sammamish under heavy fir cover, and its chimneys get the wet season the NOAA normals show for Sea-Tac: about 73% of the 40.34-inch annual total falls between October and March, with November the wettest month. The region records about 60 days a year at or below freezing but only about 4 that stay frozen all day, so water pooled on a chase cover or in a crown freezes overnight and thaws by noon, again and again. That cycle cracks saturated brick and keeps chase covers wet long enough to rust through.

Moss flourishes in the PNW's wet winters and springs and spreads fastest October through April on shaded, slow-drying surfaces. Sammamish's tree canopy means the shaded side of a chase stays green and damp for most of that stretch, and rot in the siding follows.

Sammamish is mostly single-family subdivisions built from the 1970s through the 2010s, with the oldest homes near Pine Lake and Inglewood and the newest in Trossachs and along the plateau's north end. The 1980s-and-later homes typically have factory-built fireplaces: a metal flue in a wood-framed, sided chase with a sheet-metal cover. The 1970s homes near the lakes typically have brick masonry chimneys, and many of those now carry an insert.

So most plateau jobs are chase covers, chase rot and cracked refractory panels, with crowns and caps on the older lake-side brick and liner checks where an insert was added.
