Regrading, reshaping the slope of your yard, is the most direct fix for surface water. If rain sheets toward your foundation, or a low area turns into a pond after every storm, the ground itself is sending water the wrong way. Regrading sends it back.

Yard regrading slope away from a house foundation The ground next to the house is shaped so it slopes downward away from the foundation, so surface water runs away from the home instead of pooling against it. water flows away ground slopes away from the foundation foundation
Regrading shapes the ground so it slopes away from the foundation and water runs off instead of pooling.

How regrading works

The goal is simple: the ground should fall away from your house and toward a place water can safely go. A regrade adds, removes, and re-shapes soil to create that consistent slope, a bit steeper right next to the foundation, then easing out across the yard. Done well it's invisible; the yard just looks like a yard, and the water quietly leaves. Often it's paired with a swale, a shallow, planted channel, to guide water along a deliberate path instead of wherever gravity last left it.

When regrading is the right fix, and when it's not

It's the right call for:

  • water pooling against the foundation;
  • a low spot that collects surface water every storm;
  • ground that visibly slopes toward the house;
  • a patio or addition that changed how water runs.

It's not enough on its own when:

  • the water is subsurface (springs, a high water table), which needs a French drain;
  • there's no room to establish slope (tight side yards between houses), so a drain may be the only option;
  • the source is roof runoff, so start with downspouts.

Regrading moves surface water. It can't fix water that's already underground. That's a drain's job.

Regrading, Delco's slopes, and clay

Two things make grading matter more in Delaware County. First, the rolling terrain: on a sloped Delco lot, even a small reverse-grade near the house gathers a lot of water, and a good regrade has to work with the larger slope, not against it. Second, the clay: because water doesn't soak in, getting the surface slope right is often the whole difference between a dry yard and a wet one; there's no forgiving sandy soil to absorb a grading mistake. On older lots, decades of settling are a common culprit; ground that drained fine in the 1980s may now tilt the wrong way.

What regrading costs

Cost tracks the area being reshaped and how much soil has to move. A small fix at one corner of the house is modest; re-sloping a whole back yard, trucking in fill, and re-establishing the lawn is a bigger project.

Yard regrading FAQs

How much slope does a yard need to drain?
The ground should fall away from the house over the first several feet, then keep draining across the yard. The exact grade depends on your soil and layout, with practical limits before a slope looks or feels too steep. The point is a consistent fall away from the foundation. A contractor sets it to your site.
Will regrading ruin my lawn?
There is disruption, since reshaping ground means disturbing grass, but a good regrade finishes with fresh topsoil and seed or sod, and the lawn comes back. The trade is a few weeks of recovery for a yard that finally drains.
Regrading or a French drain, which do I need?
Rule of thumb: regrading for water on the surface (pooling, or sheeting toward the house); a French drain for water in the soil (a wet line, or a spot that stays soggy in dry weather). Plenty of yards need both: regrade the surface, drain the subsurface.
Can I just add soil against the foundation myself?
Adding a little soil to improve slope is a reasonable DIY start, with two cautions: keep soil well below the siding and any wood, and never cover weep holes or vents. If it takes more than a few bags, or the grade needs to change across the whole yard, hire a pro, and call PA 811 before any real digging.
