Your Willow Springs basement gets finished only after the sump, the discharge and the drainage are right, so the new rooms stay dry.
Every basement we finish begins with a moisture check and whatever drainage or sump work the house needs. After that the crew frames on treated bottom plates, insulates the outside walls, and runs electrical and any plumbing rough-in for a bath or wet bar. Drywall, ceilings, flooring, doors, trim and paint finish it, and we handle the permit and inspections along the way. Full design-and-build basements go through our ONIT Restoration brand, the same company with a crew that does basements all day, and ONIT Solutions handles repairs to finished basements, partial finishes and single trades like framing or drywall.
We cover Willow Springs from I-294, Archer Avenue and Willow Springs Road. The village sits in Cook County along the Des Plaines River, with forest preserves along the river and Burr Ridge next door. If your lot slopes toward low ground or your sump runs hard every spring, we want a backup pump, a clear discharge line pointed away from the foundation, and downspouts carried out before any finished wall goes in. A finished basement turns a sump failure from a mopping job into a tear-out, so that work comes first.

We check the pump, the pit and the check valve, and add a backup pump if you want one before the walls close.
Water the sump pushes out and water off the roof both need to land well away from the foundation, and we fix the lines that do not.
Treated bottom plates, a gap off the foundation, and insulation that will not hold water against the wall.
The pit stays reachable inside a framed closet with a door, so servicing it never means cutting drywall.
Circuits, lighting and outlets to code, and drain and water lines if a bath or bar is in the plan.
An egress window for any bedroom, then drywall, ceilings, flooring, doors, trim and paint, with permits and inspections handled.
Our free estimate includes a look at the sump, the discharge and the grading, and the written scope lists any water work separately from the finish work. If we open a wall and find something nobody could see, we price it in writing and wait for your approval. Work is scheduled around the inspections, and we book around the days we said. When it is done, we walk the basement with you, open the sump closet and show you where every shutoff is.
