A French drain installation includes trenching a sloped channel, lining it with filter fabric, laying perforated pipe on a gravel bed, backfilling with clean drain rock, and restoring the surface. French drains redirect subsurface water away from foundations, patios, and low-lying yard areas. This estimate reflects Sacramento-area pricing for 2025-2026.

While Sacramento's summers are dry, heavy winter rains (November-March) can saturate clay soils and cause standing water. French drains are essential for homes with poor natural drainage in the Sacramento Valley.

North Highlands is located in Sacramento County (Sacramento Metro). Working-class suburb with affordable mid-century housing. The local utility provider is SMUD.

French Drain Installation in North Highlands — FAQ

How deep should a French drain be?+

Most residential French drains are 18-24 inches deep. For foundation drainage, the trench bottom should be at or below the footing level. Deeper drains intercept more groundwater but cost more to install.

Will a French drain solve my yard flooding?+

French drains are effective for subsurface water and slow-draining soils. For surface water runoff, you may also need a surface drain or channel drain. A drainage assessment will determine the best solution.

How long does a French drain last?+

With proper filter fabric and clean drain rock, a French drain lasts 20-30+ years. Fabric prevents silt from clogging the gravel and pipe, which is the main cause of premature failure.

Can I install a French drain myself?+

Small, shallow French drains are a feasible DIY project. However, drains near foundations, under hardscape, or requiring utility locates are best handled by a professional to avoid damage and ensure proper slope.
