Chimney Chase Repair in Sammamish, WA
Chimney chase rot repair: framing, sheathing, siding, flashing and a new chase cover. It is a tall box exposed to weather on every side, and a rusted cover or missing roof flashing can let water run inside it for years. We strip the chase, rebuild the framing and sheathing, and finish it with new siding, flashing and a sloped cover that sheds water. We serve homeowners across Sammamish and nearby Redmond and Bellevue.

Why chimney chase repair comes up so often in Sammamish
Wood-framed chimney chases rising above steep roofs are a familiar sight in Sammamish neighborhoods built in the 1980s and 90s. Their flat steel caps rust, pool water and leak into the chase, and in shaded areas like Pine Lake, the chase framing and siding rot from the inside out. Snow sitting on the cap adds to the problem. A pitched cover that sheds both rain and snow replaces the old cap. Underneath, we rebuild the decayed framing and plywood, re-side the chase to match, and re-flash its base where it meets the roof.
Sammamish is largely a 1980s through 2000s city, built out across the plateau above Lake Sammamish. Pine Lake, Klahanie and Beaver Lake neighborhoods are full of large two-story homes with tall walls, steep roofs and big attached decks, usually sided in cedar, hardboard or early fiber cement. Sahalee homes around the golf course tend to be larger and more custom. Along the East Lake Sammamish slope and in Inglewood you find older lake cabins next to newer view homes. Many lots are generous and heavily treed, with decks stepping down toward wooded backyards and greenbelts.
The plateau sits several hundred feet above Lake Sammamish, so Sammamish often gets colder winter nights and more snow than the lowlands nearby. That means more freeze-thaw cycles on decks, stairs and siding. Dense evergreens shade many homes for much of the day, and with long stretches of rain, wood stays damp from fall through spring. Moss grows quickly on roofs and deck boards. On the lake-facing slope, homes also catch wind coming up from the water, which drives rain into west walls.

Neighborhoods and permits in Sammamish
Pine Lake and Beaver Lake homes sit under thick tree cover, so fascia, deck boards and north walls take most of the damage. Klahanie’s 1980s and 90s homes often have hardboard siding nearing the end of its life. Around Sahalee, larger custom homes have more complex rooflines and more flashing joints to fail. On the East Lake Sammamish slope, view decks and west walls get direct wind and rain off the lake.
Minor matching repairs to boards or trim are usually handled without paperwork. Bigger decks, framing work and whole-wall siding jobs tend to need approval first. We reach out to the City of Sammamish during the estimate stage, so you know what to expect, and our team handles applications and inspection visits if a permit applies.
