If your Palos Park house has a walkout or a sloped lot, we finish the basement so the daylight side and the buried side both stay dry and warm.
Our crew takes a basement from the moisture check through the final coat of paint. We fix drainage or sump problems before anything gets covered, frame on treated bottom plates, insulate, and rough in electrical and any plumbing for a bath or wet bar. Then come drywall, ceilings, flooring, doors, trim and paint, with permits and inspections handled by us. Full design-and-build basement projects run under our ONIT Restoration brand, the same company with a crew that does basements all day, and ONIT Solutions takes repairs, partial finishes and single trades like framing or drywall.
We cover Palos Park off Route 45, 123rd Street and McCarthy Road, with the Palos and Sag Valley forest preserves along its edges. Wooded lots are part of the character in this Cook County village near Orland Park and Palos Heights. If your basement walks out to the yard, one wall stands mostly above grade and the rest are buried, so we frame and insulate them differently. Window wells on a wooded lot fill with leaves, and a clogged well drain lets water in, so we check the wells and their covers before we finish the wall behind them.

We check window wells, well drains, downspouts and grading on the uphill side before framing starts.
The above-grade wall gets framed and insulated like an exterior wall, and the buried walls get basement-rated insulation over the concrete.
Every bottom plate that touches concrete is pressure treated and sealed at the slab.
Code requires an emergency escape opening for a basement bedroom, which on a walkout can be the door to the yard and on a buried wall means an egress window and well.
Circuits, lights and outlets, plus drains and supply lines for a bath or bar, inspected before we close the walls.
Drywall, ceilings, flooring, doors, trim and paint to finish the space.
We look at the basement and walk the outside of the house, because grading and window wells matter as much as the walls. The written estimate covers both, and anything we find later gets priced in writing for your approval before we touch it. Once the permit is issued, we schedule framing, rough-in, inspection, insulation and drywall in that order and book around the days we said. A final walkthrough inside and out closes the job.
