Dallas sits in a humid subtropical climate where sudden downpours and poor drainage quickly saturate clay soils around foundations. When the ground slopes toward the house or downspouts empty next to the wall, water pools against the footing and triggers settlement cracks that widen during the hot, dry summers. We evaluate slope at multiple points around the perimeter, identify low spots near patios or driveways, and install new swales or extend downspouts far enough to carry water into the street or approved drainage areas. Local code requires positive drainage away from the structure within the first ten feet; we document grades before and after so homeowners can verify compliance.
Edge cases we see daily include tight lots in Uptown Dallas and Oak Lawn where neighboring driveways block natural flow, and older homes in East Dallas with buried downspouts that collapse under tree roots. In these situations we often combine regrading with French drains placed below the grade beam or surface channels tied to a pop-up emitter. We use perforated pipe wrapped in filter fabric, clean washed gravel, and a minimum one-percent slope to avoid standing water that breeds mosquitoes. Before any excavation we locate irrigation lines and cable utilities so the repair does not create new problems.
Mild winters mean crews can work year-round, yet we still schedule around the brief cold snaps that can freeze shallow trenches. Every job includes a final walk-through with the homeowner so they understand how to maintain the new slope and where to watch for future erosion near the Bishop Arts District or Lake Highlands properties we commonly service. Proper drainage corrections reduce the chance of future foundation movement far more effectively than simply patching cracks after the fact.
Exterior Grading & Drainage Corrections Services We Offer
✓French Drain Installation
Installs perforated pipe and gravel trenches that intercept groundwater before it reaches the foundation, protecting homes in low-lying areas like Deep Ellum and North Dallas.
✓Yard Regrading and Swale Creation
Reshapes soil to create positive slope away from the house and adds shallow swales that direct runoff to the street or approved outlets.
✓Downspout Extension and Redirect
Extends downspouts and adds elbows or pop-up emitters so roof water exits at least six feet from the foundation instead of pooling at the wall.
✓Surface Drainage Channel Installation
Places grated or open channels across patios and driveways to capture sheet flow before it enters the home or saturates the soil.
✓Sump Pump and Discharge Line Setup
Adds a sump basin and exterior discharge line that pumps collected water well away from the structure during heavy rain events.

How it works
- 1
Site Assessment
We measure existing grades at multiple points, note downspout locations, and check for signs of standing water near the foundation.
- 2
Plan And Permit Review
We create a drainage plan that meets Dallas code for positive slope and submit any required paperwork for work in historic districts.
- 3
Excavation And Installation
Trenches are dug, pipe or channels are placed with proper slope, and backfill is compacted to prevent future settling.
- 4
Final Grade And Walk-Through
Soil is raked to final slope, turf or mulch is replaced, and we demonstrate how the system works during a rain event.
Pricing
Cost depends on lot size, soil conditions, and whether underground utilities must be relocated. We provide written estimates after the site visit.
