Frequently Asked Questions
How much does a French drain cost?
French drain installation costs $25-$100 per linear foot. Yard drains (30 LF) run $1,000-$2,500. Foundation perimeter drains (75 LF) cost $2,500-$5,500. Deep exterior drains cost $50-$100/LF. Interior basement drains run $40-$85/LF.
Is a French drain worth it?
Yes, French drains cost $2,000-$5,000 and prevent water damage costing $5,000-$50,000+. They're essential for wet basements, soggy yards, and foundation protection. Proper drainage also prevents mold and structural damage.
How long does a French drain last?
French drains last 30-50 years when properly installed with quality materials. PVC pipe lasts indefinitely. Gravel eventually silts up. Clean-out access points allow maintenance. Annual checks prevent clogs from roots or debris.
Can I install a French drain myself?
Yes, for shallow yard drains. Rent a trencher ($150-$300/day) for easier digging. Use perforated pipe, landscape fabric, and clean gravel. Maintain 1% slope (1 inch drop per 10 feet). Deep foundation drains are best left to pros.
