# How much does a French drain cost in Kansas City? > Premier Gutters KC — NDS Certified Professional Drainage Contractor, Kansas City metro. (816) 469-9563 · https://premiergutterskc.com/answers/french-drain-cost-kansas-city/ ## Short answer A yard French drain (40 to 80 feet) costs $1,500 to $3,800 installed in the Kansas City metro. A full foundation-perimeter French drain runs $4,000 to $10,000+. Single buried downspout extensions — often all a home actually needs — are $300 to $700 each. Price drivers are trench length, depth, KC clay and rock, access for equipment, and the outlet design. ## \1 2026 Kansas City market ranges (what we actually quote): Single buried downspout extension: $300–$700 — Schedule 40 PVC or corrugated pipe, 15–25 ft from the house to a daylight or pop-up outlet. Whole-house downspout system (5–7 downspouts): $1,500–$3,500 — every downspout buried to an engineered outlet. Yard French drain (40–80 ft): $1,500–$3,800 — perforated HDPE pipe, filter fabric, washed rock, daylight outlet. Foundation-perimeter French drain: $4,000–$10,000+ — around the foundation, tied to discharge, grade restored. Dry well: $800–$2,200 — when there's no downhill outlet to daylight. What moves the price in KC specifically: our clay is slow-digging and heavy, rock pockets are common south of the river, tight gate access can force hand-digging, and the outlet matters — a clean daylight exit is cheaper than a dry well. Restoration (seed vs sod) is the most commonly forgotten line on competitor quotes; make sure it's in writing. Beware of quotes that seem too cheap. A French drain without filter fabric, washed rock, and a real outlet is a buried clog that fails in 2–3 years. Ask any bidder: What pipe? What fabric? Where does the water GO?
