Huntsville, AL · French drains
The water is still here on Wednesday.
That's Madison County clay. It holds water like a closed fist. Alabama puts about 55 inches of rain on it in a year. This soil sends it sideways, into the crawl, against the slab, into the same low spot your mower sinks into a week later.
- Why it's still wet. Clay. About 55 inches of rain a year. The soil will not take it down.
- The sock-pipe. Usually not for long. Fines load the sock. Trench smears. No outlet, no drain.
- What we dig. French drains wrapped for clay. Daylight downhill, or a legal storm path. Not a soak pit.
That's Madison County clay. Huntsville and the rest of the county sit on red clay that holds water like a closed fist. Alabama puts about 55 inches of rain on it in a year, and there isn't a real dry season. December and March are often as wet as summer. Sand would swallow that. This soil sends it sideways, into the crawl, against the slab, into the same low spot your mower sinks into a week later.

What we actually do
- French drains that are dug and wrapped for clay, not a corrugated sock from the big-box aisle
- Yard drains at 18 to 24 inches when the problem is the lawn
- Footing-depth perimeter drains when the problem is the crawl or the slab
- Discharge that daylights downhill, or a legal path to the storm system, not a hole in clay we pretend is a dry well
What a job usually costs
Typical national ranges, clay makes the high end more likely. Not a bid. We'll quote after we see slope and where the water is allowed to go.

- Deep clay or footing-depth trench: about $50 to $90 per foot
- Typical 60 to 80 ft run: about $1,800 to $5,000

When to request a quote
Water standing more than a day after rain. Water at the foundation. A crawl that smells like a pond. A DIY pipe that silted shut. A neighbor downhill from you on Green Mountain. Do not wait for the next 2-inch storm if the last one was in the house.

If your lot is red clay in Madison County, the sock-pipe story, the mountain discharge story, and the city storm-drain story are why. How long a clay French drain lasts, French drain versus a surface drain, and French drain cost in Huntsville, are the next questions.
Questions people ask first
Why is my Huntsville yard still wet two days later?+-
Clay. About 55 inches of rain a year. The soil will not take it down. Grade and a real outlet do the work.
Will a big-box sock-pipe work in Madison County?+-
Usually not for long. Fines load the sock. Trench smears. No outlet, no drain.
Can I just dig a dry well / soak pit?+-
In this clay it fills and stays. That is not a storm system. The storm-drain page is the long version.
How much does a French drain cost in Huntsville?+-
For planning, about $30 to $50 per foot for a shallow yard drain and about $50 to $90 per foot for a deep clay trench. Common 60 to 80 foot jobs often come in at $1,800 to $5,000. Not a bid. Clay and outlet complexity push cost up. Call for a site quote. Length, depth, clay digging, and where water is allowed to go change the number. Published market figures, not our bid. The cost page is the long version.

Use the clay-soil designer, then the form. Not a guessed bid.
Can you hook my French drain to the city's storm inlet?+-
Only if Engineering allows it and any permit is real. Not a stealth pipe. Huntsville Utilities is not that office. City Engineering: 256-427-5300.
French drain vs surface drain. What's the difference?+-
Surface drain for water still on the lawn or pavement. French drain for water in the soil, at the foundation, or in the crawl. Clay lots often need both. A surface, channel, or catch-basin system grabs water on top of the ground. A French drain is a gravel trench with perforated pipe that intercepts water moving in the soil. The comparison page is the long version.
Yard drain or footing drain?+-
Wet lawn, dry house: 18 to 24 inches. Wet crawl or water at the slab: footing-depth. The tool asks this.
How long does a French drain last in clay?+-
Often 15 to 25 years when gravel, fabric, grade, and outlet are right. Sock pipe in clay can fail in a few seasons. Build quality dominates: washed open-graded stone, fabric suited to fines, real slope, and a working outlet. The lifespan page is the long version.
Hampton Cove vs Green Mountain vs Jones Valley?+-
Same clay. Different slope and neighbors. Daylight on a mountain lot is how you pick a fight downhill. Jones Valley is often the catch. Hampton Cove bowls need a path out, not a hole in the middle.
Do I need a permit?+-
Small private trench on your lot often does not. Land disturbance, a new outfall, or a public-system tie-in can. City Storm Water Management Manual is the book. We'll flag it.
How do I get a quote?+-
Call (256) 900-1970 or use the form. Say standing water, wet crawl, or both, and the neighborhood. We'll follow up.
