Chimney Repair, Sweep & Inspection in Issaquah, WA

Local Conditions

Chimney problems we see in Issaquah

Issaquah sits where the lowland meets the Cascade foothills, and its chimneys carry the Puget Sound wet season measured at Sea-Tac: roughly 29.65 inches from October through March, about 73% of the annual total. The region touches freezing about 60 days a year while winter lows average near 37°F, so water in a crown crack or a mortar joint freezes overnight and thaws by day repeatedly; saturated brick that freezes cracks and spalls. Hillside homes on Squak and Tiger Mountain sit higher and stay in tree shade longer, so their masonry dries more slowly.

Moss spreads fastest October through April on shaded, slow-drying surfaces, and under the fir canopy on Issaquah's wooded lots the shaded side of a chimney rarely dries out between storms.

Issaquah's housing spans from the early-1900s houses around Olde Town to the dense 2000s construction in the Highlands and Talus, with a wide band of 1970s–90s homes on Squak Mountain, in Klahanie and around Providence Point in between. The older valley homes typically have brick masonry chimneys; the Highlands, Talus and most Klahanie homes typically have factory-built fireplaces in sided chases; and the wooded acreage lots toward Mirrormont typically run wood stoves into either a masonry flue or a metal class A chimney.

That means crowns and repointing downtown, chase covers and refractory panels on the plateau plats, and heavy creosote cleaning on the stove-heated lots.
