Platinum Earthworks.

The state insures Platinum Earthworks under an excavation risk class, which matches the bulk of what it advertises: clearing lots, grading, soil stabilization, trenching for utilities and digging foundations. It also lists road building and site development. The business first held a Washington registration under this name in 2022, and the state lists David Guga as a principal since 2024. Washington registers contractors through the Department of Labor & Industries, and this one holds a general contractor registration. The work suits a homeowner who wants one small crew to dig, shape and finish a yard: excavating for a retaining wall, setting pavers, laying sod and running irrigation. It also fits trenching or foundation digging ahead of a home addition, or grading and base work for a new driveway. Large commercial development is outside its focus, and electrical and plumbing aren't trades it lists, so those pieces of a project go to other contractors. Around Spokane, season drives dirt work. Winter frost and spring thaw leave soil soft and saturated, which makes grading and compaction harder to get right, so heavy excavation and base prep usually go better once the ground dries out. Freeze-thaw cycles are also hard on pavers and retaining walls built on a thin or poorly drained base, so ask how deep the base goes and where water will go. Dry summers favor concrete and hardscape but stress new sod, so plan irrigation before planting.
