Basement Finishing in Downers Grove

Replace a worn-out basement finish with rooms built right from the concrete up. We cover Downers Grove.

Basement finishing and refinishing in Downers Grove

Some basements come to us bare, and some come with an old finish that needs to come out. Either way, we start at the concrete with moisture readings on the walls and slab, a sump test and any drainage correction before new framing. The rebuild uses treated bottom plates, proper clearances around the mechanicals, insulation, and electrical and plumbing rough-in where you want a bath or wet bar. Drywall, ceilings, flooring, doors, trim and paint finish it, with permits and inspections handled.

We reach Downers Grove off I-88 and I-355 and work across the village, from Ogden Avenue and Butterfield Road to Main Street and the blocks around the Metra station, in DuPage County. If your basement already has paneling or a drop ceiling from an earlier finish, we pull a section before we price the job, because what sits behind it decides the scope. Paneling glued to block can hide damp spots, rotted plates or wiring that never saw an inspector. We would rather find that at the estimate than halfway through the job.

Basement Finishing by ONIT Solutions

What a Downers Grove basement job covers

Tear-out of an old finish

We remove old paneling, carpet and ceiling tile and haul it away so we can see the walls and floor.

Moisture and sump check

Walls and slab get tested, the sump gets run, and any drainage fix happens before new framing.

New framing on treated plates

Replacement walls sit on pressure-treated bottom plates, framed to leave service room around the furnace and panel.

Wiring brought up to code

We inspect old basement wiring and install new circuits, outlets and lighting to code.

Insulation and plumbing

We insulate the walls and rim joists and rough in drain and supply lines for a bath or wet bar.

Drywall and finishes

Drywall, ceiling, flooring, doors, trim and paint go in once inspections pass.

How a refinish runs from start to walkthrough

A free visit gets us into the basement, and if there is an old finish, we open a test spot with your okay. The written estimate covers tear-out through paint, and anything hidden that turns up later gets priced in writing for your approval first. We pull the permit through the village and book the crew around the inspections. The last step is a walkthrough where we test every outlet and switch and fix what you find.

  • Old finish opened up before pricing
  • Tear-out and haul-away included
  • Moisture tested at bare concrete
  • Old wiring inspected and corrected
  • Hidden problems priced before work
  • Every outlet tested at the end
Full basement design and build runs under our ONIT Restoration brand. Same company, a crew that does basements all day.
FAQ

Basement Finishing in Downers Grove: questions

Can you fix part of our finished basement instead of redoing all of it?
Yes. Repairs to an existing finished basement, partial finishes and single trades like drywall or framing are ONIT Solutions work. A full design-and-build basement runs under our ONIT Restoration brand, same company, with a crew that does basements all day.
Is a permit needed to refinish a basement in Downers Grove?
If the work adds walls, wiring or plumbing, yes. The village issues it, and we pull it and handle the inspections. Cosmetic work like paint or new flooring usually does not need one, and we tell you which side your job falls on.
How long does a refinish take?
Tear-out adds a few days at the front. After that, the timeline follows the scope and the inspections. You get a written schedule before we start.
Do you work in towns around Downers Grove?
Yes. We finish basements in Westmont, Lisle, Woodridge and Lombard.
Can I text you photos first?
Yes. Send photos of the walls, ceiling and any water stains to (815) 585-1750 and we will tell you what we need to see in person.
