503 Excavation

503 Excavation is a Portland-area Excavating contractor that handles core earthwork needs such as site preparation, grading, trenching, and drainage for residential and small commercial projects. Schedule a site walk to review access constraints, soil conditions, and utility locates (call 811), then request a written, line-item estimate that includes haul-off, backfill, and final grading. Clarify timeline, daily start times, equipment to be used, and who handles permits and inspections (e.g., septic, utility tie-ins, or street cuts). Ask for recent project photos and references, and confirm licensing, insurance, and erosion-control plans so you can compare bids confidently and avoid surprises.
