Typical Florida installed cost for french drain / yard drainage: $1,500–$9,000 — a curated 2026 planning range, not a bid. The most accurate figure for your home comes from a verified local pro (free, below).
French drain cost in Florida is priced by linear foot and depth — a gravel-and-pipe trench that routes water away — with a shallow yard drain far cheaper per foot than a deep foundation drain.
Plan it — not an emergency.
Common causes:
• Length in linear feet and how deep the trench goes
• A yard drain versus a deep foundation drain
• Digging conditions, roots, and obstacles
• Where the water is routed and any outlet work
• Installing a drain without confirming where the water should go
• Too shallow or short a drain for the actual water problem
• No outlet, so the drain just relocates standing water
• No proof of insurance or a track record — Florida doesn't license this trade, so those are what protect you
How does a French drain fix yard drainage?
It's a gravel-filled trench with a perforated pipe that intercepts water and carries it to a lower outlet — away from the house or the soggy spot. In Florida's heavy rain and flat lots, it gives water a path it doesn't otherwise have. The key is a real outlet so the water actually leaves, not just moves a few feet.
What makes a French drain more or less expensive?
Length and depth, mostly. A shallow yard drain across a soggy patch is far cheaper per foot than a deep drain along the foundation. Digging through roots, rock, or tight access adds to it, as does the outlet — where the water goes. A drain sized and routed for the actual problem is what's worth paying for.
French drain / yard drainage: $1,500–$9,000 (typical ~$4,000)
By linear foot and depth; a yard drain is cheaper per foot than a deep foundation drain. Routing water away is the goal.

Florida does NOT issue a state license for this trade (local licensing was preempted for most non-structural trades). What protects you instead: general-liability insurance, workers’ comp, and a real track record — exactly what our verification checks.
Whether a permit applies depends on scope — when in doubt, ask the county building department before work starts.
Basis: HB 735 (2021) local-license preemption.
