Give guests a real bedroom downstairs in Willowbrook, with the egress window code requires and a well that drains. We cover Willowbrook.
We open every basement job by looking for water. Walls and slab get checked, the sump gets run, and any drainage repair is finished before framing starts. Then come walls on treated bottom plates, clearances for the mechanicals, insulation, electrical, and plumbing rough-in for a bath or wet bar when you want one. Drywall, ceilings, flooring, doors, trim and paint go in after inspections, and we pull the permit.
We work in Willowbrook off I-55 and Route 83, along 63rd Street in DuPage County. A basement bedroom needs an egress window by code, which means an opening big enough to climb out of and a well outside that lets you do it. The well needs a drain at the bottom tied into the drain tile or a gravel base, or it fills with rain and becomes the newest leak in the house. If your yard has a fence, a patio or a gas meter close to the foundation, we pick the window spot around them at the estimate.

We test walls and slab, run the sump and fix drainage before any wall goes up.
We plan the opening to code size, with a well, a drain at the bottom and a cover if you want one.
Walls go up on pressure-treated plates, with a closet if you want one and clearance kept at the mechanicals.
Walls and rim joists get insulated, and we plan supply and return air so the bedroom heats and cools.
We wire outlets, lighting, and the smoke and carbon monoxide alarms code calls for near a bedroom.
Drywall, ceiling, flooring, door, trim and paint finish the room.
We visit for free and send a written estimate with the egress window location and size spelled out. If the dig or the cut turns up something nobody could see, like a buried line or a crack, we price it in writing and wait for your yes. We pull the permit through the village and set the crew's days around the inspections. Once the room is finished, we walk it with you, open the egress window together, and fix anything left on the list.
Call or text (815) 585-1750 and we will price the room at a free visit. We will mark the egress window spot with you, inside and out.
