If you’re a homeowner or property manager dealing with basement flooding, yard drainage issues, or foundation water seepage, you’ve likely heard about French drains as a solution. But how much does it actually cost to install a French drain in New York’s diverse boroughs and Long Island?
In this blog, we’ll break down the French drain installation cost, including the factors that influence pricing, and provide location-specific estimates for Long Island, Brooklyn, Queens, and the Bronx.
What Is a French Drain?
A French drain is a trench filled with gravel or rock containing a perforated pipe that redirects surface water and groundwater away from an area. It’s one of the most effective systems for resolving moisture problems around foundations, basements, or soggy yards.
Average French Drain Installation Cost in NY
The average cost of French drain installation in NY ranges between:
- $30 to $70 per linear foot for exterior drains
- $60 to $100 per linear foot for interior systems
- Total project cost: typically $2,500 to $15,000, depending on size, complexity, and location
Cost Breakdown by Factor
1. Linear Footage
Most French drain systems are priced by the linear foot, meaning the longer the trench, the higher the cost. For instance:
| Length (Feet) | Low-End Estimate | High-End Estimate |
| 20 ft | $600 | $2,000 |
| 50 ft | $1,500 | $5,000 |
| 100 ft | $3,000 | $10,000 |
2. Type of Installation
- Exterior French Drain (yard or foundation perimeter):
- Easier access, lower cost
- $30-$70 per linear foot
- Easier access, lower cost
- Interior French Drain (basement or crawl space):
- Requires breaking concrete floors, sump pump installation
- $60-$100+ per linear foot
- Requires breaking concrete floors, sump pump installation
3. Soil Conditions
Different soil types impact the difficulty of excavation:
| Soil Type | Impact on Cost |
| Sandy or loamy | Easier digging, lower cost |
| Clay-heavy | Harder digging, higher cost |
| Rocky terrain | May require special tools, increases cost |
4. Labor Costs in NY
Labor is a major component of French drain pricing in New York. On average:
- $50-$100 per hour per crew member
- Urban areas like Brooklyn and the Bronx typically have higher labor rates due to limited access and logistical challenges.
- Suburban areas like Long Island may allow faster work and lower per-hour costs.
5. Accessibility
The more obstacles (like fences, landscaping, or pavement), the more time and labor are needed. Hard-to-reach areas can raise the price by 20-30%.
6. Additional Components
French drain systems may require the following extras:
- Sump pump installation – $500 to $1,500
- Drainage basin or dry well – $300 to $1,000
- Downspout tie-ins – $200 to $600
- Landscaping restoration – $500 to $2,000
