FAQ

Basement Finishing in Willowbrook: Questions

What does a basement wellness suite involve?

A cedar sauna, a cold plunge with its own dedicated circuit and drainage, often a steam shower and heated floors. Below grade, the engineering matters as much as the finishes, so we build in proper ventilation and vapor control from the start. Wellness suites pair naturally with a gym on the same level.

Can we fit a bar and a theater in the same lower level?

In most upscale Willowbrook homes, yes. We zone the floor so the theater gets sound isolation and controlled lighting while the bar stays open and social, with sight lines and traffic flow worked out during design. The itemized quote breaks each zone into its own pricing so you can adjust scope room by room.

How quickly can you get out to look at our basement?

Fast. ONIT Restoration is based in Willow Springs, minutes from Willowbrook, so scheduling a free in-home design consultation is simple. We walk the space, measure, talk through what you want the level to do, and follow up with an itemized quote. From signed contract, most builds run 6 to 12 weeks.
