Lewis County is a big place. It stretches from the I-5 corridor towns of Centralia, Chehalis, Napavine and Winlock west to Pe Ell and east through Onalaska, Mossyrock and Morton toward the Cascade foothills. Sandrini Construction Inc has served communities across the county since 1976. Ben L. Sandrini founded the company in Chehalis, and Kathy and Ron Sandrini have owned and run it since 1991.

Building for Lewis County Conditions
Construction here means dealing with long, wet winters, rural properties with wells and septic systems, and in some areas the floodplains of the Chehalis River and its tributaries. Lewis County has a history of serious flooding, and that affects how homes and additions should be sited and built. We plan for drainage, moisture control, crawl space ventilation and proper foundations on every project, because that’s what keeps buildings sound in this climate.
Permits in Lewis County
Projects in unincorporated Lewis County go through the county’s permitting office, and projects within city limits go through each city. After nearly 50 years of local work, we know the process well, and we handle the permits for you.
