How much to finish a basement in Madison, WI?
Cost per square foot, egress for bedrooms, moisture approach, and planning rough-ins so you don’t pay twice.
“What’s the ballpark per square foot?”
$30–$70/sq ft is a realistic local range depending on bath additions, bedroom (egress), and finish level.
“Do I need an egress window for a bedroom?”
Yes—required for any legal bedroom. It also improves natural light and resale.
“How do you handle moisture?”
We start with a moisture check, use smart subfloors or LVP, insulate properly, and keep drywall off the slab plane.
Pro tip: If you might add a bath later, stub-in plumbing now to save thousands later.
