What Affects Crawl Space Costs in Oregon?
Oregon's wet marine climate, particularly in the Willamette Valley, makes crawl space moisture control essential. Portland and the surrounding metro area receive 35-45 inches of rain annually, with persistent drizzle from October through May keeping crawl spaces damp. The volcanic soils in the Cascades region drain well but can shift over time. Labor costs in the Portland metro are above the national average and have risen with the city's growth. Eastern Oregon is much drier and has fewer crawl space moisture issues. Oregon's strict energy code requirements for crawl space insulation add to project costs but improve long-term efficiency.
