Arlington Heights, Cook County

Basement Finishing in Arlington Heights

Finish your Arlington Heights basement from the stairs down, with safe, well-lit steps, a dry foundation and every inspection passed.

Basement finishing for Arlington Heights homes

Our basement finishes follow one rule: nothing gets covered until we know the space is dry. We check the walls and floor and fix any drainage or sump issue first, then frame on treated bottom plates with clearance around the mechanicals, insulate, and run electrical and any plumbing rough-in for a bath or wet bar. Bedrooms get the egress window code requires, and the finish covers drywall, ceilings, flooring, doors, trim and paint. Full design-and-build basements are handled by ONIT Restoration, a brand of our same company with a crew that does basements all day, and ONIT Solutions takes repairs to a finished basement, partial finishes and single trades like framing or drywall.

We work in Arlington Heights every week, coming up Route 53 and using Arlington Heights Road and Northwest Highway to get around town and past downtown. The stairs are the part of a basement finish people forget. Once the basement becomes living space, the stairway needs a solid handrail, enough headroom, and light switches at the top and bottom, and an open side needs a guard. If your stairs were built for a storage basement, we bring them up to what the inspector will look for.

FAQ

Basement Finishing in Arlington Heights: questions

Do the basement stairs need to change when I finish the basement?
Often they do. Living space below means a proper handrail, a guard on open sides, enough headroom and switched lighting, and the inspector will check all of it.
Does Arlington Heights require a permit for finishing a basement?
A basement finish that adds walls, wiring or plumbing generally needs a village permit. We check what Arlington Heights requires, file the permit and schedule each inspection.
Do you work in towns near Arlington Heights?
Yes. We finish basements in Palatine, Rolling Meadows and Schaumburg too.
How long does a basement finish take?
Size, plumbing and inspection dates all move it, so there is no single answer. You get a written schedule with your estimate.
How do I set up an estimate?
Call or text (815) 585-1750. We will come look at the basement and the stairs and write it all up.
