Diamond Grading, Inc.

Diamond Grading, Inc. is an excavating contractor serving the Fontana, CA area, handling site prep, grading, trenching, and drainage for residential and commercial projects. For a smooth start, request an on-site assessment with a written scope, timeline, and line-item pricing that includes soil export/import and compaction requirements. Ask them to coordinate underground utility locates, clarify permit needs and erosion-control measures, and map equipment access and haul routes to minimize disruptions. Before booking, confirm licensing/insurance, start date, and change-order policy, then schedule your grading window to align with your foundation, concrete, or landscaping trades.
