Keep Your Property Dry with Professional French Drain Installation
New York battles with frequent flooding episodes that are getting worse every year. A French drain system is one of the most effective ways to direct water away from your home’s foundation and landscaping when one hits. Whether you’re battling basement flooding or soggy yards, Zavza Seal has the expertise to design and install the right drainage solution.
We proudly serve Long Island, Brooklyn, Queens, and The Bronx, providing homeowners and property managers with long-lasting drainage systems.
Benefits of French Drains
Improper drainage is a leading cause of:
- Foundation cracks
- Basement flooding
- Mold and mildew
- Erosion and yard damage
- Structural instability
Installing a French drain helps:
- Redirect groundwater away from structures
- Prevent water pooling around your home
- Protect landscaping and hardscaping
- Reduce hydrostatic pressure on foundation walls
Types of French Drain Solutions We Offer
At Zavza Seal, we customize each system based on your property’s layout, soil type, and drainage issue. Our French drain options include:
Interior French Drains
Ideal for wet basements and crawl spaces. Installed along interior walls, these systems collect and channel water to a sump pump for removal.
Exterior French Drains
Placed along the perimeter of your home to intercept surface and groundwater before it reaches your foundation.
Curtain Drains
Used in yards and landscapes to divert surface water away from problem areas.
Deep French Drains
Installed at a greater depth to manage high water tables or severe drainage issues.
French Drain Installation Costs: What to Expect
The cost of installing a French drain depends on several factors. The total linear footage needed plays a major role, as longer systems require more materials and labor. The type of drain—whether it’s an interior or exterior system—also impacts cost, with exterior installations typically involving more complex work. Soil conditions and trench depth are important too; rocky or compacted soil and deeper digs increase labor time and expense. Additionally, if the area is difficult to access, specialized equipment or extra labor may be necessary. In the New York area, most French drain projects generally range from $2,000 to $7,500.
