The cost to install a french drain in Bend ranges from $2,160 to $10,810, with most homeowners paying around $5,400. Your actual cost depends on several factors specific to your home and the Bend 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 Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
French drain installation in Bend generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.
Low humidity reduces pipe condensation issues. Water conservation fixtures may qualify for local rebates. Evaporative cooling systems are a cost-effective alternative to traditional AC.

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 ($200–$300/day), buy drainage gravel and perforated pipe, and maintain proper slope (1% grade). Interior basement drains are best left to professionals.
