Drainage & Grading

French drains typically cost $20–$60 per linear foot installed in Georgia (average $30–$45), depending on depth, pipe type, gravel, fabric, discharge method, and site access. A 50–100 ft system often runs $1,500–$6,000. Red clay requires careful excavation and backfill for best performance—we provide exact quotes on-site.

Minor surface grading or small French drains usually do not. However, extensive regrading, large retaining walls (4+ ft), or systems altering major runoff may need permits/inspections for stormwater compliance. We check local codes and handle permitting if required.

Yes—regrading to create positive slope away from the house (1 inch per foot minimum) is one of the most effective ways to reduce hydrostatic pressure and prevent foundation/basement leaks from pooling water. We combine it with French drains or downspout extensions for comprehensive protection.

We use regrading for better runoff, French drains/catch basins for subsurface water, erosion-control blankets or vegetation on slopes, and retaining walls if needed—preventing soil loss and stabilizing red clay hillsides common in Cumming properties.

We use topdressing, soil amendments, and precise grading (often with skid steer) to fill low spots, improve surface flow, and aerate compacted clay—creating a smooth, well-draining lawn that resists puddling and supports healthy grass growth.

If the exact location of your septic tank (or drain field) is unknown, we always prioritize safety and compliance before starting any excavation, grading, regrading, French drain installation, or hardscape project in Cumming or Forsyth County.

Many older homes or properties don’t have clear records or visible markers, but here’s how we handle it:

• First step: We ask you to check with the Forsyth County Environmental Health Department (770-781-6909) for any existing septic permits, as-built drawings, or records (they’ve kept files since the 1970s and can often provide layouts or approvals tied to your address/parcel).
• Common DIY clues (while we assess): Look for the sewer line exit from your home (usually in the basement or crawl space), follow it outward 10–25 feet for the tank lid, or note greener/lusher grass strips in the yard that might indicate the drain field.
• Professional locating: If records aren’t available or clear, we recommend (and can coordinate) a professional septic locator using tools like ground-penetrating radar, probe rods, or camera scoping—often through a licensed septic contractor or specialist. This avoids accidental damage.
• What if we hit it? Accidental damage during work (e.g., cracking the tank or crushing lines) can lead to costly repairs, backups, or system failure—plus potential health/environmental issues. We carry full insurance and take every precaution (hand-digging in suspect areas, marking utilities via 811 call first). If damage occurs despite care, we work with you and pros to repair quickly, but prevention is always our goal.

Before any digging begins, we’ll discuss your property history, walk the site carefully, and flag potential septic zones. If needed, we’ll pause and recommend a locate service to protect your system and avoid expensive surprises. This keeps your project safe, legal, and smooth—especially important with our clay soil and sloped yards.
