Hiring grading contractors in Washington

Grading is the shaping of ground to a designed elevation and slope. Rough grading moves the bulk of the earth to bring a site close to plan; finish grading dials in the last few inches so a pad is level and a yard sheds water. The number that matters is fall: building codes call for the ground to drop at least six inches in the first ten feet away from a foundation, and a lawn or gravel area needs roughly a two percent slope to drain. Crews do this with a dozer, a skid steer with a grading bar, or a motor grader on larger lots, checked against a laser or GPS grade stake rather than by eye.

What grading work costs

Rough grading is typically quoted by the hour for the machine, $100 to $200 for a dozer or skid steer with operator, or by the acre at roughly $1,000 to $5,000 depending on how much earth moves. Regrading a residential yard to fix drainage usually falls between $1,000 and $6,000. Finish grading a pad or lawn area is often priced per square foot, in the $0.50 to $2.50 range.

Ranges are national and approximate; regional labor rates, material prices and site conditions move them in both directions.

Common projects

  • Building pads cut and filled to engineered elevation with compaction testing
  • Regrading yards that hold water or slope toward the house
  • Subgrade for driveways, gravel roads, sports fields and landscape beds

What affects a quote

  • Cut and fill balance: whether dirt can be moved on site or has to be hauled in or out
  • Compaction requirements, which decide whether a roller and density testing are on the job
  • Access, the number of grade stakes or survey control points, and topsoil to strip and replace

Grading FAQ

What does grading work cost?

Rough grading is typically quoted by the hour for the machine, $100 to $200 for a dozer or skid steer with operator, or by the acre at roughly $1,000 to $5,000 depending on how much earth moves. Regrading a residential yard to fix drainage usually falls between $1,000 and $6,000. Finish grading a pad or lawn area is often priced per square foot, in the $0.50 to $2.50 range.

What should I share when requesting a grading estimate?

A grading plan or a simple sketch showing where water should end up is the most useful thing you can send. Point out low spots, existing drains, septic fields, tree roots and anything the machine needs to steer around.

What can change the cost of grading work in Washington?

The main cost items are cut and fill balance: whether dirt can be moved on site or has to be hauled in or out; compaction requirements, which decide whether a roller and density testing are on the job; access, the number of grade stakes or survey control points, and topsoil to strip and replace. A site visit helps the crew see which ones apply.

Do grading projects in Washington need permits?

Many cities and counties require a grading permit once the job moves more than a set volume, often 50 cubic yards, or changes drainage toward a neighbor. Disturbing an acre or more triggers a stormwater permit and an erosion control plan in most states.
