Frequently Asked Questions
Does a window well need a drain?
Yes. If you have a window well that has any kind of rain or melted snow pooling at the bottom, then it needs a drain. Otherwise, major flood damage to your home’s foundation and contents is inevitable if heavy rains come down on top of an improperly drained window well.
Are french drains in window wells complicated to install?
No. In fact, window well french drains are easier to install than a typical french drain in the yard. But you must be careful when digging the trench for your corrugated drain pipe so as not to damage any underground lines such as electrical cables or plumbing pipes.
