What drives where your project lands
- Scope — one room vs. multiple rooms vs. whole-home is the largest single factor.
- Finish level — stock vs. semi-custom vs. custom cabinetry, tile, and fixtures.
- Structural & systems work — moving walls, plumbing, or electrical adds cost.
- Home age & condition — older King County homes can hide surprises behind the walls.
- Permits & timeline — jurisdiction, inspections, and scheduling all factor in.
