No. NailIt is DIY-only and shows materials costs only. You are the installer, so labor is free—you only pay for pipe, gravel, fabric, and supplies.
Typical residential french drains are 50–200 linear feet. Measure your drainage area and slope requirements. Deeper or longer drains use more pipe and materials, raising your total cost.
Larger projects need more pipe, gravel, and fabric. Heavy clay or soggy soil may require extra gravel layers or longer drainage lines. Use NailIt to adjust project size and get an updated materials estimate.
