Add a quiet office, a guest room or a play space downstairs in Woodridge, built on a basement we checked for water first. Woodridge is on our regular route.
Before we talk layout, we talk water. Our crew checks the foundation walls and slab, runs the sump and fixes any drainage issue, and nothing gets covered until that is done. Framing goes up on pressure-treated bottom plates with the clearance your mechanicals require, followed by insulation, electrical, and plumbing rough-in if you want a bath or wet bar. Then we hang drywall, build ceilings, lay floors, set doors and trim, and paint. Full design-and-build basement projects are handled by 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 Woodridge off I-355 and I-55, on 75th Street, Route 53 and Woodridge Drive in DuPage County. Townhomes and single-family homes sit side by side here, and the paperwork differs between them. If you own a townhome, the association may need to sign off before work starts, and a wall shared with a neighbor has fire and sound rules a detached house does not. In either kind of home, we can add sound insulation between the joists over an office or a bedroom so footsteps upstairs carry less.

We test walls and slab, run the sump and correct drainage before any wall is framed.
For a townhome, we provide the scope, drawings and certificate of insurance your association asks for.
Bottom plates are pressure-treated, and the furnace, water heater and panel keep their service space.
Walls and rim joists get thermal insulation, and ceilings over quiet rooms can get sound batts.
Circuits, outlets, lighting and plumbing for a bath or bar go in before drywall.
We hang and finish drywall, build the ceiling, install flooring, doors and trim, and paint.
We look at the basement for free and send a written estimate, and for a townhome we include what the association will want to see. Any added work, like sealing a crack we uncover, comes to you as a written price first. We pull the permit through the village, set the inspections, and book the crew around them. A final walk with you closes the job, and we fix every item on your list.
