Grading and Drainage Fix Where Water Goes

Grading and drainage work controls where water travels on your property. We reshape the slope so runoff leaves your yard, add drains where water collects underground, and pipe roof water away from the foundation. The right fix depends on whether the water comes over the surface, up from the soil or off your roof.

Green Acres has been working in the Wilmington area since 1998. As a grading and drainage contractor in Wilmington, DE we start with a site walk, explain what is causing the water, and quote the repair that fits.

Signs You Need It

Signs Your Yard Has a Drainage Problem

Most drainage problems announce themselves after a storm. Call us if you see any of these:

  • Water standing in the lawn for a day or more after rain
  • A wet basement, damp crawl space or water lines on the foundation
  • Mulch, soil or gravel washing out of beds, or bare channels in the lawn
  • Soft, spongy ground, moss, or grass that yellows in wet spots
  • Gutters or downspouts that empty right at the house
  • Soil that slopes toward the home instead of away from it

Cost Drivers

What Affects the Cost of Grading and Drainage

No two yards cost the same, so we quote after a site visit. These factors move the price most:

  • Area and length. Regrading a small corner differs from reshaping a full back yard, and a drain run of 30 feet differs from 150.
  • Excavation depth and soil. Clay, rock and roots slow digging and raise labor.
  • Where the water exits. A nearby daylight outlet is simpler than a long pipe run or a dry well.
  • Access. Narrow gates and slopes can keep equipment out and mean hand work.
  • Materials. Pipe, stone, fabric, catch basins and fill dirt vary with the design.
  • Restoration. Re-seeding or sod, plantings, and any patio, walkway or driveway we must cut through.
  • Permits and approvals. Some jobs need town, county or HOA sign-off.

Ask about financing for larger projects.

Permits & Local Rules

Permits, Utilities and Drainage Rules in New Castle County

Rules differ by municipality, subdivision and lot. Small corrections to your own yard often need nothing. Larger land-disturbing projects can come under sediment and stormwater requirements, and some towns and HOAs review changes that affect runoff. Water must also not be redirected onto a neighbor’s property.

We confirm what applies to your address before work starts, and we call 811 so buried utilities are marked before anyone digs.

FAQ

Grading and Drainage Questions Wilmington Homeowners Ask

Drainage trench with gravel and perforated pipe on a Delaware property
How do I know if my yard needs regrading or a French drain?

Water that sits on the surface after rain usually points to a grading problem, so the fix is reshaping the slope. Soil that stays soggy for days, or water that seeps out of a hillside, points to underground water, which a French drain handles. Many yards need both, and a site walk tells us which.

How much does yard drainage work cost?

Price depends on the length of the run, how deep we dig, the pipe and stone required, how far the water must travel to a safe outlet, and what we have to cut through or restore, such as lawn, patios or driveways. We write up a fixed scope after seeing the property, so you can compare it line by line.

Will regrading or a French drain stop water in my basement?

It often helps, because most basement water starts as surface or roof runoff sitting against the foundation. Moving that water away addresses the cause. Water that comes through cracks or a failed wall membrane is a waterproofing problem, and we will tell you plainly if that is what you have.

Do I need a permit to regrade my yard in New Castle County?

Small corrections to your own yard often need no permit. Larger earth-moving jobs can trigger sediment and stormwater rules, and some towns and HOAs review drainage changes. We confirm what applies to your address before we dig, and we call 811 so buried utilities are marked.

What is the difference between a French drain and a swale?

A French drain is a buried, gravel-filled perforated pipe that collects water under the surface and carries it to an outlet. A swale is a shallow planted channel on the surface that guides runoff along a chosen path. Drains suit soggy ground, and swales suit sloped yards where runoff moves in sheets.

When is the best time to fix a drainage problem?

Right after a heavy rain is the best time to diagnose, because the water shows us exactly where it goes. We can build most of the year, but frozen ground slows excavation. Fixing drainage before you build a patio, wall or fence also saves tearing finished work back out later.
