Split your basement into rooms that each stay warm in winter and cool in summer. We work in Burr Ridge every week.
Our crew treats water as step one in any basement. We check the walls and slab, test the sump, and get drainage or sump work done before anything is covered. Framing follows on treated bottom plates, laid out to keep service space at the furnace, water heater and panel, then insulation, electrical and plumbing rough-in for a bath or wet bar. Once inspections pass, we finish drywall, ceilings, flooring, doors, trim and paint. Full design-and-build basements run under our ONIT Restoration brand, same company, with a crew that does basements all day, and repairs to a finished basement, partial finishes and single trades like framing or drywall are ONIT Solutions jobs.
We cover Burr Ridge off I-55 and Route 83, along County Line Road, and the village straddles DuPage and Cook counties. If your basement is large enough to split into a family room, a bedroom and a gym, each closed room needs its own supply air and a path for return air, or the doors stay shut on a stuffy space. We look at the duct trunk at the estimate and plan where the new runs and returns go before the walls are drawn. The same planning covers lighting circuits, so one breaker does not carry the whole floor.

We test walls and slab, run the sump and finish drainage work before any wall is framed.
We lay out rooms on pressure-treated bottom plates and keep service space around the mechanicals.
We plan supply and return air for every closed room and frame the chases the duct runs need.
Foundation walls and rim joists get insulated, with sound batts available between rooms.
We split lighting and outlets across circuits and rough in any bath or wet bar plumbing.
Drywall, ceilings, flooring, doors, trim and paint go in room by room.
A free visit lets us see the whole basement and the duct trunk, and your written estimate breaks the job into rooms and phases. If something turns up, like a wall crack behind stored boxes, we price it in writing and wait for your approval. Permits go through the village, the crew is booked around inspections, and we protect the stairs and the floors above. At the end we walk each room with you and fix anything that is not right.
