Cost to French Drain Installation in New York City, NY (2026)

If you’re budgeting a french drain installation in New York City, most projects run $3,050-$12,200, 22% above the $5,000 national average. What moves that number most is usually one thing: Interior vs Exterior Installation. On its own it can swing the cost by $1,000 - $5,000, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Get quotes for both interior and exterior solutions. Interior drains are often less expensive because they don't require heavy excavation equipment or landscape restoration.

In the Northeast (where New York City sits): High water tables and older homes with stone foundations create strong demand. Rocky soil in New England adds excavation costs.
