8 Ways to Increase Natural Light in Your Basement

Add Windows

Every basement needs at least one egress window to satisfy the fire code, and every basement bedroom requires an additional one, but there’s no limit. The more you add, the brighter things will be down there.

It’s best to install windows during new construction, but you can do it anytime. It costs from $2,500 to $5,000 to dig a window well and install an egress window in the foundation wall. A half window placed above the foundation — which requires no well — costs $1,000 to $2,000 to install.
