Get a dry, warm lower level you will actually use, with the water question settled before a single wall goes up. Plainfield is on our regular route.
Every basement we take on starts with a moisture check, because drywall over a damp wall fails from the back. If the walls or floor show water, we sort out the drainage or sump work before anything gets covered. From there the job is framing with treated bottom plates, insulation, electrical, 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 cover Plainfield every week, on Route 59, Route 126, 127th Street and Caton Farm Road, with I-55 on the east side of Will County. If the sump pit in your Plainfield basement sits right where you want the family room, we frame a closet or a hinged panel around it so the lid stays reachable and the pump can be swapped without cutting drywall. The same goes for the cleanouts, the main water shutoff and the electrical panel. A finished basement still has to let a plumber or an electrician get to what they need.

We look at the walls, the floor and the sump before anything else, and any drainage or pump work is done first.
Bottom plates that sit on concrete are pressure treated, and walls stand off the foundation so insulation fits behind them.
Foundation walls get insulated before drywall so the room holds its heat in January.
Outlets, lighting and circuits go in to code, plus supply and drain lines if you want a bath or a wet bar.
Walls and ceilings are hung, taped and finished, with access panels left where valves and cleanouts need them.
The floor goes down, doors get hung, trim gets run and the paint closes it out.
We walk the basement with you, check the walls and floor for moisture, and measure every room you want. The written estimate lists each trade as its own line, so you can see what the water work costs apart from the finish work. If we open a wall and find something nobody could see, we price it in writing and wait for your yes. Inspections set part of the pace, and we book our days around them. At the end we walk every room with you and test every outlet and door.
