Basement Finishing in Clarendon Hills, IL

A bookshelf that swings open on commercial pivot hardware. Behind it, a wine room, a cigar lounge, or a quiet bar. Clarendon Hills homes from the teardown era sit on tall, dry foundations that were made for this kind of lower level, and finish expectations in the village run just as high as they do next door in Hinsdale.

ONIT Restoration designs and builds to that standard, with millwork and materials matched to the main floor. We manage permits, provide itemized quotes, and complete most projects in 6 to 12 weeks. Consultations are free and in home, and financing is available on larger builds.

FAQ

Basement Finishing in Clarendon Hills: Questions

What does a hidden speakeasy door actually cost?

Concealed bookshelf and panel doors on commercial pivot hardware typically run 8 to 20 thousand dollars per door inside a larger project, depending on size, millwork, and what sits behind it. The rooms they conceal, wine storage, cigar lounges, whiskey rooms, are built fully code compliant. Your itemized quote prices the door as its own line.

Can the basement finish really match our main floor?

Yes, and in Clarendon Hills it should. We carry your trim profiles, door styles, flooring tones, and lighting temperature downstairs so the lower level reads as part of the house rather than an addition to it. Material selections happen during design, and every choice appears in the itemized quote before work begins.

Our home is one of the older village houses. Does that change the project?

It changes the starting point, not the care. Older Clarendon Hills homes get an honest evaluation of ceiling height, moisture, and structure before we design anything, and the plan follows what the foundation supports. Teardown-era homes usually build straight away. Either way, permits, itemized pricing, and a 6 to 12 week build are standard.
