Red Diamond Construction

Red Diamond Construction is a Spokane, WA excavating contractor offering site prep, grading, trenching, and foundation digs for new builds and renovations. Ask for an on-site walk to assess soil conditions, drainage, access, and equipment needs, and request a line-item estimate that breaks out excavation, haul-off/import, compaction, and erosion control. Before work begins, confirm permits and 811 utility locates, a written schedule with weather contingencies, and who is responsible for inspections and compaction testing. For a build-ready finish, ask about laser grading tolerances, driveway or base prep, and final cleanup and stabilization.
