Window well maintenance

Know when to install and how to maintain window wells to keep water and dirt from entering your home.

Window wells have a job to do

Window wells protect basement windows from dirt and water and direct stormwater into the weeping tile system for your home. A window well is a U-shaped, ribbed, light metal product that surrounds the window and is tight against the basement wall. A window well should be at least a foot below the bottom of the basement window.

Proper construction of a window well

A window well should extend at least 12" below the bottom of the basement window.
12" of washed rock should be placed in the window well. The top of the rock layer should be 6" from the bottom of the window.
The top of the well should be at least 3-4" above your grade.

When to install a window well

You need to consider installing a window well if the bottom of the basement window frame is at or near ground level. Measure before you buy. Window wells come in different sizes.
If your existing window well is too low, you need to install a window well extension to achieve proper grade away from your house.
You may also want to install window well covers to prevent precipitation and debris from entering the window well.

Ensure your window wells function properly

Clean the inside area of all dirt and debris in the spring and fall and after major weather events.
Do not use your window wells as a storage space. This may disrupt the drainage function of the window well and compromise your foundation or windows and lead to basement flooding.
Check to make sure the loose gravel or rock at the bottom of the well is 3 to 6" below the bottom of the window. This will allow water to drain and filter to the weeping tile reducing the impact of water on your foundation.
Grade the sod outside the window well in the same way as the rest of the house.

Always consider proper grading when installing or maintaining window wells.

For further information, contact a landscape or foundation professional to assess your property or existing window wells.
