The Difference

The Largest Unfinished Room in Your House

Your basement is roughly a third of your home's footprint, already framed, roofed, and paid for. Most contractors treat it as cheap square footage: a drop ceiling, builder-grade carpet, one overhead light. We treat it as the best room in the house waiting to happen, and we design it with the same intention as any kitchen or great room.

FAQ

Basement Finishing Questions

Why does ONIT Restoration only build basements?

Because below-grade work has its own rules. Moisture, ceiling height, soffits, sound, and light all behave differently under the house. Specializing means every project makes us better at exactly the thing you are hiring us for.

What areas do you serve?

Will County and the western DuPage corridor: Joliet, Plainfield, Shorewood, New Lenox, Lockport, Homer Glen, Orland Park, Bolingbrook, Romeoville, Aurora, Naperville, Downers Grove, Oak Brook, Hinsdale, and Burr Ridge.

Do you publish pricing?

Yes. Our cost guide lays out realistic per square foot ranges for the Chicago suburbs, and every project gets a written, itemized quote after a free in-home consultation. No mystery numbers, no expiring discounts.

Do I need a permit to finish my basement?

In nearly every case yes, especially with a bathroom, bedroom, or new electrical circuits. Permits and inspections are handled as part of every project.

Do you offer financing?

Financing options are available for larger builds. We will walk through what fits during your free consultation.

How long does a full basement build take?

Most projects run 6 to 10 weeks of construction after design and permits. We give you a schedule up front and a single point of contact until the final walkthrough.
