The cost to install a french drain in Fort Worth ranges from $1,840 to $9,210, with most homeowners paying around $4,600. Your actual cost depends on several factors specific to your home and the Dallas-Fort Worth market.
French drain projects are priced per linear foot; longer drains mean more trenching, gravel, and pipe, scaling costs linearly.
Deeper drains (18–24 inches) handle more water but require more excavation labor and gravel fill than shallow 12-inch drains.
Washed drainage gravel is essential for proper function but costs more than standard fill. Skimping on gravel quality leads to clogging.
4-inch perforated pipe is standard for residential French drains. Larger diameters handle more water but cost more per foot.
Trenching through landscaped areas requires restoring sod, mulch beds, or plantings after the drain is installed.
The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
French drain installation in Fort Worth generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.
Hiring a pro? Make sure they're properly licensed: see Texas plumber license rules.
UV-resistant PEX and proper insulation for hot water lines are important. Tankless water heaters perform exceptionally well in warm climates due to higher incoming water temperatures.
While possible for experienced homeowners, French drain installation involves significant complexity. In Fort Worth, you may still need a licensed pro for permits and inspections. DIY could save $2,093–$2,691 in labor.

Most French drain installation projects in Fort Worth take 2–5 days to complete. The timeline depends on project scope, contractor availability in the Dallas-Fort Worth metro area, and seasonal demand. Scheduling during Fort Worth's off-peak season (typically late fall through early spring) can reduce wait times and may lower costs.
A properly installed French drain with filter fabric and quality gravel lasts 20–30+ years. Without filter fabric, fine sediment clogs the gravel and pipe much sooner. Using perforated PVC pipe (not corrugated) also extends lifespan significantly.
A simple exterior French drain is a feasible DIY project if you're comfortable with heavy digging. You'll need to rent a trencher, buy drainage gravel and perforated pipe, and maintain proper slope (1% grade). Interior basement drains are best left to professionals.
