How much does a French drain cost?
A French drain in Florida costs roughly $10–$50 per linear foot installed, according to industry cost data from sources like HomeGuide and Angi — which puts a typical project around $1,000–$5,000. Length, depth, soil, and the type of drain drive the range. French drains are common here for good reason: Florida's heavy rain, flat lots, and high water table create standing water and poor drainage that can soak your yard and pool against the foundation. A French drain moves that water away — and getting the slope and discharge right is what makes it work.
Key takeaways

- Florida's heavy rain, flat lots, and high water table make drainage a common need.
- Length, depth, soil, and discharge point drive the price.
- Proper slope and a real discharge point are what make it actually work.

What a French drain costs
French drains are priced per linear foot, with the type and conditions as variables. Here's the 2026 picture from HomeGuide's French drain cost data:
| Type | Typical cost | Notes |
|---|---|---|
| Exterior yard drain | ~$10–$35 / linear ft | Surface/shallow drainage |
| Deeper / curtain drain | ~$25–$50 / linear ft | Protects foundation |
| Typical project | ~$1,000–$5,000 | Depends on length/depth |
| Discharge solutions | varies | Dry well, daylight, pop-up emitter |
A worked example: running a French drain along a chronically soggy side yard of an Orlando home to carry water to the street or a dry well lands in the low-to-mid four figures, while a deeper foundation curtain drain or a long run through hard soil costs more. The total scales with how much trench you need and how deep.
What a French drain does
A French drain is, at its core, a gravel-filled trench with a perforated pipe at the bottom. Water seeps into the gravel, enters the pipe through its holes, and is carried by gravity to a safer discharge point — away from wherever it's causing trouble. It's a simple, proven concept: give water an easy path to somewhere it won't harm anything.
Homeowners use them to solve specific problems: a soggy or flooding section of yard, a low spot that won't drain, water pooling against the foundation, or runoff from a slope. The pipe daylights to a lower area, a street, a dry well, or a pop-up emitter. The key is that water needs both a collection point and a destination — a drain to nowhere just moves the puddle.
Why Florida needs drainage
Drainage is a bigger deal in Florida than many states, for several reasons at once. Our heavy, intense rain dumps a lot of water fast in the wet season. Many lots are flat, so water doesn't naturally run off. The soil is often sandy on top but clay underneath, which can perch water near the surface. And the high water table means the ground is already saturated in places. Together, that's a recipe for standing water, soggy yards, and water against the foundation.
Chronic wetness isn't just an annoyance — it kills grass, breeds mosquitoes, and can undermine the foundation and feed moisture problems. Managing where water goes is a recurring Florida theme, the same logic behind sloping a paver patio or driveway away from the house and keeping gutters flowing. A French drain is the dedicated tool when a specific area won't drain on its own.
What drives the price
Several factors move a French drain quote. Length is the base — more trench, more cost. Depth matters: a deeper drain (to protect a foundation, for instance) costs more to dig than a shallow yard drain. Soil and access count — hard digging, roots, or a hard-to-reach area add labor. And the discharge solution factors in: daylighting to a low spot is cheap, while a dry well or tying into storm drainage costs more.
Whether it's a simple exterior yard drain or an interior/foundation perimeter drain changes the scope significantly. Get the quote to specify the length, depth, and especially the discharge plan — where the water actually ends up is what determines whether it works.
Getting it designed right
Here's what separates a French drain that solves the problem from one that doesn't: diagnosis and design. A good installer first figures out where the water is coming from and where it should go, then designs the drain with proper slope (water flows by gravity, so it must run consistently downhill to the discharge) and a real outlet. A drain laid flat, or one that discharges to a spot that also floods, won't fix anything.
So when you get quotes, ask how they'll establish slope and where the water will discharge — not just where they'll dig. Be wary of a quote that just proposes "a drain along the wet area" without addressing the destination. Done right, a French drain reliably dries out a problem area for years; done carelessly, it's an expensive trench that still puddles.
Where to start
Start by identifying exactly where water pools or your yard stays soggy, and note where lower ground or a street is for discharge. Our outdoor living directory and Orlando city page list local drainage and landscaping companies, with more across the full directory. Get the length, depth, and discharge plan itemized, make sure the installer diagnoses the water's source and slope, and pair it with good gutter drainage so roof water isn't adding to the problem.
FAQ
How much does a French drain cost in 2026? Industry cost data puts a French drain around $10–$50 per linear foot installed, so a typical project often runs $1,000–$5,000. Length, depth, soil, and whether it's an interior or exterior drain drive the range.
What does a French drain do? It's a gravel-filled trench with a perforated pipe that collects and redirects water away from a problem area — a soggy yard, a low spot, or water pooling against the foundation — to a safer discharge point.
Why are French drains common in Florida? Florida's heavy rain, flat lots, sandy-then-clay soils, and high water table cause standing water and poor drainage. A French drain moves that water away, protecting the yard and foundation from chronic wetness.
What drives French drain cost? Length and depth of the trench, soil conditions, accessibility, where the water discharges, and whether it's a yard drain or an interior perimeter drain. Longer, deeper runs and hard digging cost more.
Will a French drain fix standing water in my yard? Usually, when designed correctly — it needs proper slope and a real discharge point. A good installer diagnoses where the water comes from and where it should go, not just where it pools.
