Make the right decision for your French drain direction
Perforated drain pipes in French drains should face down when half-perforated to let water enter from below and flow toward your exit point.
Expect to pay $500 to $18,000 for professional French drain installation, with average costs around $9,250 depending on your yard and drainage needs.
Your French drain system works best with river rock or granite chips underneath the pipe to prevent clogging and maintain proper water flow.
Hiring a local French drain professional provides reliable help with trench digging and pipe connections, keeping your foundation protected from excess water and flooding.
Excess water surrounding your home’s foundation is a cause for concern, which is where a French drain system can save the day. But should French drain holes face up or down?
This type of drainage system uses a perforated pipe that allows extra water to move from one point to the next so that it doesn’t pool. Our guide can help you figure out which positioning works best and when to hire a French drain installer.
A french drain provides a sunken channel for water to disperse into the soil surrounding your home. Installing this type of system requires digging a trench and hooking up pipe connections, among other tasks, so it's best to hire a professional french drain installation company for this project.
For French drains, the direction the pipe perforations face depends on the use and type of system. No one direction is wrong unless it's being used in a way that would prevent your French drain from working properly.
If you have a more intricate French system that incorporates downspouts and a perimeter drain inside the basement, the perforations in your drain pipe should face up. This direction allows the downspouts to work with streaming water to keep debris and silt from collecting inside the pipe and clogging it.
The drain holes on your pipe should face down if the pipe is half perforated. As water moves through the ground from the top of the slope, the holes allow water to come in from the bottom and flow down to the exit point. Your French drain would still technically work if the holes were facing up, but the water wouldn’t travel as fast so it wouldn’t be as effective.
A French drain is an outdoor system used to direct water away from your home and down toward an exit point to prevent water damage or flooding. Most French drain systems include a trench filled with rock or gravel, with a perforated pipe for excess water to flow through. Your French drain dimensions depend on the needs of your property, but most systems range from 8 to 24 inches deep, with a four-inch diameter pipe running five to 10 feet.
A French drain provides a sunken channel for water to disperse into the soil surrounding your home.

It’s best to get quotes from at least three companies before you lock one down so you have a good idea of the scope of work and the average cost. The cost of installing a French drain system ranges from $500 to $18,000, or $9,250 on average. The total cost depends on yard size, drain size and type, and labor costs.
