French Drain Installation in Mt. Juliet, TN

When a French drain is the right fix

A French drain intercepts water moving through or across the soil and redirects it before it causes damage. In Wilson County, that usually means one of three situations: water pooling in a low spot of the yard, runoff collecting against the foundation, or a hillside pushing water toward the house every time it storms.

Our red clay subsoil is the reason this area needs them more than most. Clay is nearly impermeable — rain that would soak in elsewhere runs sideways here until it finds the lowest point. If that low point is your crawl space, no amount of surface landscaping will fix it.

What a correctly built system includes

• Filter fabric lining the trench — the number one thing skipped by cut-rate installs. Without it, clay silt clogs the gravel within a few seasons.
• Washed gravel, not crusher run — limestone fines compact into a solid mass and stop draining.
• Perforated pipe sloped at least 1% — checked with a laser level, not eyeballed.
• A legal discharge point — daylight, pop-up emitter, or dry well. Water has to have somewhere to go.
• A water test before we leave — we run water through the system and show you it working.

French drain cost in Mt. Juliet, TN

Most residential systems here run $2,500–$12,000. The drivers are trench length, depth, how hard the discharge point is to reach, and whether equipment can access the work area or the dig is by hand. A single 40-foot downspout-relief run is at the bottom of that range; a full perimeter system with catch basins is at the top.

We quote fixed prices after a free site walk. If someone quotes you a per-foot price over the phone without seeing where the water goes, be suspicious — the discharge is usually the hard part.

Interior vs. exterior drains

We install exterior systems: the goal is stopping water before it reaches the structure. If water is already entering a basement from below the footing, an interior perimeter drain with a sump may be the right tool — and we'll tell you that at the evaluation rather than sell you an exterior system that won't solve it.
