Water pooling near a house can lead to foundation damage and soggy yards. One of the best fixes is a French drain. The cost for French drain installation depends on the size of the project and site conditions.
From our experience, these systems are priced by the linear foot. They often include surface drains to handle standing water and allow for upkeep. In this guide, we explain the main cost factors, how long drains last, and what to expect when investing in one.
What is a French Drain System?
A French drain is a trench filled with gravel and a pipe that redirects water away from the house. It lowers the risk of flooding and keeps soil stable.
Learn how French drains work:
- Water flows into the gravel trench.
- A perforated pipe carries water away.
- Discharge lines move it farther from the house.
Pro Tip: Ask if surface drains are part of the setup. They make cleaning easier and prevent clogs.
How Much Does French Drain Installation Cost?
The price is based on the linear foot. Each property is different, so costs vary.
Here are the main cost factors:
- Length of System: Longer drains mean more pipe, gravel, and labor.
- Soil Type: Dense soil may need deeper digging.
- Drain Upgrades: Extra discharge lines can move water 20–30 feet away.
- Site Access: Yards with tight spots or heavy landscaping take more time.
Projects that require more feet of drain or add upgrades will increase the cost.
Life Expectancy of a French Drain
French drains do not last forever. Over time, soil and sediment can clog the pipe. Without upkeep, the drain stops working.
Here’s how to extend the life:
- Flush surface drains each season.
- Check the discharge ends to see if water flows out.
- Install cleanouts for easier checks.
Key Takeaway: With upkeep, a French drain lasts many years. Without it, the system may fail sooner.
Problems That May Happen After Installation
- Sometimes, water discharge creates new issues. Low areas near the outlet can stay soggy year-round.
- Wet ground can make mowing difficult.
- Extensions may be needed to move water farther.
