Gain finished rooms downstairs that stay dry, because we check the foundation and the sump before a single stud goes up. We work in Homer Glen every week.
Every basement we finish starts with water, because nothing we build down there survives a damp wall. We test the walls and slab, look at the sump and its discharge, and fix drainage before any framing goes in. From there it runs in order: framing on treated bottom plates, insulation, electrical and any plumbing rough-in, then drywall, ceilings, flooring, doors, trim and paint. Full design-and-build basements run under our ONIT Restoration brand, which is the same company with a crew that does basements all day, while ONIT Solutions takes repairs to a finished basement, partial finishes and single trades like framing or drywall.
We reach Homer Glen up I-355 and work along Bell Road, 143rd Street, 159th Street and Route 7 in Will County. Where a house sits on a large lot, the sump line can run a good length across the yard, and a frozen or crushed line sends water right back to the pit. We trace that line to where it lets out before we frame a wall near the pump. The pit itself stays open, with an access panel or a removable section, so the pump can be swapped without cutting drywall.

We test the pump, check the check valve and follow the discharge line outside before any wall closes in.
Bottom plates are pressure-treated lumber on the slab, and walls stand off the foundation so insulation fits behind them.
We leave the clearance your furnace, water heater and panel need, and frame a door wide enough to service them.
Foundation walls and rim joists get insulated to what the code and the inspector call for.
Outlets, lighting and circuits go in before drywall, along with drain and supply lines if you want a bath or wet bar.
We hang and finish drywall, build the ceiling, lay the floor, hang doors, run trim and paint the rooms.
We come out for free, look at the space and the mechanicals, and give you a written estimate that lists each phase. Anything we find once work begins, like a cracked wall that needs sealing, gets priced in writing and waits for your yes. We pull the permit and book the work around the inspection dates, so you know which days the crew is in the house. When the last coat of paint is dry, we walk every room with you and fix what is not right.
